Pourquoi les robinets-vannes tombent-ils en panne ?<\/h3>\n\n\n\n
Les causes les plus courantes de d\u00e9faillance des robinets-vannes sont l\u2019usure et la corrosion de la cale et du si\u00e8ge. Les parties int\u00e9rieures d\u2019un robinet-vanne ont tendance \u00e0 s\u2019user avec le temps. Et la corrosion peut faire coincer la cale en position ouverte ou ferm\u00e9e. Lorsque le volant est sollicit\u00e9, la tige allant du volant au coin a tendance \u00e0 se casser, rendant la vanne inutilisable.<\/p>\n\n\n\n
De plus, la garniture de tige et le joint de chapeau du robinet-vanne sont des pi\u00e8ces d'usure et doivent \u00eatre remplac\u00e9s dans le d\u00e9lai recommand\u00e9 par le fabricant, ce qui peut \u00e9galement provoquer des fuites s'ils ne sont pas remplac\u00e9s.<\/p>\n\n\n\n
R\u00c9PARATION DE VANNE-VANNE<\/h3>\n\n\n\nPuis-je r\u00e9parer les robinets-vannes ? <\/h3>\n\n\n\n
Oui, veuillez vous r\u00e9f\u00e9rer aux probl\u00e8mes et solutions suivants<\/p>\n\n\n\n
1. Probl\u00e8me\u00a0:\u00a0fuite entre le robinet-vanne et le raccord de la vanne<\/h4>\n\n\n\n1-1.Action corrective\u00a0:<\/h4>\n\n\n\n
Tout d'abord, v\u00e9rifiez si les boulons reliant la vanne au robinet-vanne sont serr\u00e9s, sinon, sa bague d'\u00e9tanch\u00e9it\u00e9 et la surface de la rainure d'\u00e9tanch\u00e9it\u00e9 de la bride entra\u00eenent souvent des fuites s'ils ne sont pas suffisamment connect\u00e9s. V\u00e9rifiez que les boulons et les \u00e9crous sont en ordre et serrez tous les boulons jusqu'\u00e0 ce que le joint soit enfonc\u00e9. Ensuite, v\u00e9rifiez la taille et la pr\u00e9cision de la surface de la rainure d'\u00e9tanch\u00e9it\u00e9 du joint et de la bride. Si la surface de contact du joint est de mauvaise taille ou trop rugueuse, r\u00e9parez-la ou remplacez-la. V\u00e9rifiez \u00e9galement la surface de contact de la bague d'\u00e9tanch\u00e9it\u00e9 et de la rainure d'\u00e9tanch\u00e9it\u00e9 de la bride pour d\u00e9tecter des d\u00e9fauts tels qu'un peu d'\u00e9rosion, des trous de sable, des trous de sable ou des impuret\u00e9s. Si c'est le cas, soudez, r\u00e9parez ou nettoyez en cons\u00e9quence.<\/p>\n\n\n\n
2.Probl\u00e8me\u00a0:\u00a0fuite du capot<\/h4>\n\n\n\n
Ce ph\u00e9nom\u00e8ne de d\u00e9faillance se produit souvent lors d'une fuite du joint d'\u00e9tanch\u00e9it\u00e9.<\/p>\n\n\n\n
2-1.Action corrective\u00a0:<\/h4>\n\n\n\n
Tout d'abord, v\u00e9rifiez que le joint s'ajuste correctement et est compatible avec la rainure du joint. En cas de probl\u00e8me, le joint doit \u00eatre remplac\u00e9 ou la rainure du joint r\u00e9par\u00e9e. Deuxi\u00e8mement, v\u00e9rifiez si le joint pr\u00e9sente des bavures, des cassures et des torsions. Si tel est le cas, le joint doit \u00eatre remplac\u00e9. Ensuite, v\u00e9rifiez la surface de la rainure du joint pour d\u00e9celer toute rugosit\u00e9 ou autre d\u00e9faut et s'il y a des d\u00e9fauts, \u00e9liminez-les ou remplacez les pi\u00e8ces endommag\u00e9es.<\/p>\n\n\n\n
Lorsque le chapeau ou le support utilise une garniture \u00e0 joint de compression, l'installation de la garniture doit \u00eatre v\u00e9rifi\u00e9e et si la garniture s'av\u00e8re install\u00e9e \u00e0 l'envers, elle doit \u00eatre retir\u00e9e et install\u00e9e selon la m\u00e9thode correcte.<\/p>\n\n\n\n
3. Probl\u00e8me\u00a0:\u00a0Fuite de la cavit\u00e9 du corps de la vanne<\/h4>\n\n\n\n
Pendant le processus de coul\u00e9e, des d\u00e9fauts de coul\u00e9e peuvent parfois appara\u00eetre dans le corps de la vanne, tels que des trous de gravier et des trous de sable. Ils sont difficiles \u00e0 d\u00e9tecter lors de l'usinage sans n\u00e9cessiter de tests non destructifs, mais une fois la pression appliqu\u00e9e sur le corps de la vanne, les d\u00e9fauts de coul\u00e9e cach\u00e9s sont r\u00e9v\u00e9l\u00e9s.<\/p>\n\n\n\n
3-1.Action corrective\u00a0:<\/h4>\n\n\n\n
Si tel est le cas, il peut \u00eatre soud\u00e9, r\u00e9par\u00e9 ou renouvel\u00e9 selon le cas selon la norme.<\/p>\n\n\n\n
4. Probl\u00e8me\u00a0: fuite du si\u00e8ge de soupape et du coin de soupape<\/h4>\n\n\n\n
4.1 Des fuites se produisent sur le si\u00e8ge de vanne et le coin de vanne, ce qui est le ph\u00e9nom\u00e8ne le plus courant lors de l'installation ou de la maintenance des vannes. Il en existe g\u00e9n\u00e9ralement deux types\u00a0: l'un est une fuite sur la surface d'\u00e9tanch\u00e9it\u00e9\u00a0; l'autre est une fuite au niveau de la racine d'\u00e9tanch\u00e9it\u00e9.<\/p>\n\n\n\n
4.1-1.Action corrective\u00a0: La premi\u00e8re chose \u00e0 v\u00e9rifier est la pr\u00e9cision de la surface de contact d'\u00e9tanch\u00e9it\u00e9 du si\u00e8ge de vanne et du coin de vanne. La surface d'\u00e9tanch\u00e9it\u00e9 doit \u00eatre meul\u00e9e et si la surface est rugueuse, retirez-la et rectifiez-la. Ensuite, v\u00e9rifiez la surface d'\u00e9tanch\u00e9it\u00e9 pour d\u00e9celer des d\u00e9fauts tels que des marques, des indentations, des trous de poussi\u00e8re, des fissures, etc. Si tel est le cas, le si\u00e8ge et la cale doivent \u00eatre remplac\u00e9s. Pour les si\u00e8ges de soupape avec ressorts de compression, v\u00e9rifiez que la force du ressort de pression r\u00e9pond aux exigences. Si la force du ressort est faible, le ressort de compression doit \u00eatre remplac\u00e9. De plus, v\u00e9rifiez que l'accouplement en forme de T entre la cale de la vanne et la tige n'est pas trop l\u00e2che et qu'il n'y a pas de pente, si c'est le cas, la cale doit \u00eatre retir\u00e9e et ajust\u00e9e \u00e0 la taille optimale.<\/p>\n\n\n\n
4.2 Lors de l'installation de la vanne, il est facile de laisser tomber des corps \u00e9trangers tels que des ch\u00e8ques de soudure, de la ferraille et des impuret\u00e9s.<\/p>\n\n\n\n
4.2-1.Action corrective\u00a0:\u00a0Nettoyer les d\u00e9bris avant l'installation. Si vous oubliez de nettoyer ou ne nettoyez pas compl\u00e8tement, la cale de la vanne n'atteindra pas la profondeur de fermeture souhait\u00e9e et provoquera une fuite, auquel cas le corps de la vanne devra \u00eatre retir\u00e9 et nettoy\u00e9.<\/p>\n\n\n\n
Le si\u00e8ge de soupape doit \u00eatre install\u00e9 \u00e0 l'aide d'un outil sp\u00e9cial. V\u00e9rifiez que le si\u00e8ge de vanne est correctement install\u00e9. Si les filetages sont moins profonds que pr\u00e9vu, le si\u00e8ge fuira. Dans ce cas, le si\u00e8ge doit \u00eatre install\u00e9 \u00e0 l'aide d'un outil sp\u00e9cial.<\/p>\n\n\n\n
Comment r\u00e9parer un robinet-vanne qui ne s'ouvre ou ne se ferme pas ?<\/h3>\n\n\n\n
La premi\u00e8re possibilit\u00e9 est que le couple de la vanne est trop important et n\u00e9cessite plus de force pour se fermer ou s'ouvrir, remplacez l'actionneur par un actionneur de plus grande taille.<\/p>\n\n\n\n
La deuxi\u00e8me possibilit\u00e9 est que, lorsque la vanne est install\u00e9e dans le pipeline, il y a une accumulation de scories de soudure ou de d\u00e9bris au bas de la vanne bloquant la fermeture de la vanne, et les d\u00e9bris doivent \u00eatre \u00e9limin\u00e9s. La troisi\u00e8me possibilit\u00e9 est que la vanne et le si\u00e8ge de vanne aient \u00e9t\u00e9 endommag\u00e9s et doivent \u00eatre r\u00e9par\u00e9s et remplac\u00e9s \u00e0 temps.<\/p>\n\n\n\n

Comment remplacer un robinet-vanne, Remplacer un robinet-vanne par un robinet \u00e0 tournant sph\u00e9rique<\/h3>\n\n\n\n
Fermez le robinet d'arr\u00eat \u00e0 l'avant pour que le fluide soit dans un \u00e9tat statique et \u00e9vacuez le fluide dans cette section du pipeline. S'il s'agit d'un robinet-vanne \u00e0 bride, vous devez retirer le boulon et l'\u00e9crou du raccordement. , nettoyez la surface d'\u00e9tanch\u00e9it\u00e9, remplacez le joint et rebranchez le nouveau robinet \u00e0 bille. S'il s'agit d'un robinet-vanne \u00e0 raccord filet\u00e9, il suffit de le visser. Dans le cas de connexions SW ou BW, coupez et soudez le nouveau robinet \u00e0 bille en place.<\/p>\n\n\n\n
Vanne \u00e0 eau<\/mark><\/strong><\/a> Probl\u00e8mes<\/h2>\n\n\n\nMon robinet-vanne est bloqu\u00e9 et ouvert, que dois-je faire<\/h3>\n\n\n\n
Si ton vanne \u00e0 opercule<\/strong> est ouvert et vous ne pouvez pas le fermer, la seule option est de le vider. Dans certains cas, les plombiers peuvent remplacer rapidement les vannes, mais cela ne pr\u00e9sente aucun risque. Dans la plupart des cas, lorsque votre robinet-vanne a un probl\u00e8me, si votre robinet-vanne est ouvert, il est pr\u00e9f\u00e9rable de vidanger l'eau.<\/p>\n\n\n\nLe probl\u00e8me que le robinet-vanne ne peut pas \u00eatre ouvert<\/h3>\n\n\n\n
Si vous avez un robinet-vanne qui ne peut pas \u00eatre ouvert, cela est g\u00e9n\u00e9ralement d\u00fb \u00e0 un axe cass\u00e9. La raison en est g\u00e9n\u00e9ralement que lorsque la vanne est ferm\u00e9e en raison d'une construction non sale, de tartre ou autre, le plombier ou le ma\u00eetre resserrera le filetage, provoquant sa rupture. Si la vanne ne peut pas \u00eatre facilement ferm\u00e9e, il est pr\u00e9f\u00e9rable de remplacer le robinet-vanne pendant la vidange de l'eau, afin d'\u00e9viter davantage les probl\u00e8mes de robinet-vanne et d'entra\u00eener des co\u00fbts suppl\u00e9mentaires.<\/p>\n\n\n\n
Comment remplacer le robinet-vanne sans perdre d'eau chaude<\/h3>\n\n\n\n
La meilleure fa\u00e7on de remplacer la vanne est de geler d\u2019abord le tuyau, puis de remplacer la vanne. La seule autre fa\u00e7on est de fermer le robinet-vanne et de d\u00e9brancher le tuyau inf\u00e9rieur. Une fois que vous avez quitt\u00e9 l'\u00e9crou sup\u00e9rieur du tuyau d'alimentation, vous pouvez changer la vanne tr\u00e8s rapidement. Cela doit \u00eatre fait par un plombier d\u2019urgence qualifi\u00e9.<\/p>\n\n\n\n
Mon robinet-vanne ne ferme pas correctement, pourquoi ?<\/h3>\n\n\n\n
La raison pour laquelle la vanne ne peut pas \u00eatre ferm\u00e9e normalement est qu'\u00e0 mesure que le robinet-vanne vieillit, vous constaterez une accumulation de salet\u00e9 ou de tartre, ce qui emp\u00eachera le m\u00e9canisme de fermeture de se fermer normalement. La meilleure fa\u00e7on de r\u00e9soudre ce probl\u00e8me est de nettoyer soigneusement la vanne ou de remplacer le robinet-vanne.<\/p>\n\n\n\n
Lors du remplacement du robinet-vanne, s'il doit \u00eatre vid\u00e9 en premier<\/h3>\n\n\n\n
Comme expliqu\u00e9 dans le paragraphe pr\u00e9c\u00e9dent, pour remplacer une vanne, il n'est pas toujours n\u00e9cessaire de la vider, \u00e0 condition d'avoir l'exp\u00e9rience et les outils pour le faire.<\/p>\n\n\n\n
Qu'est-ce qui cause la rupture du robinet-vanne<\/h3>\n\n\n\n
La raison de la rupture du robinet-vanne est que la vanne est fragile et que la pression est trop \u00e9lev\u00e9e lorsque le robinet-vanne est ferm\u00e9. Le filetage de la broche n'est pas assez profond pour p\u00e9n\u00e9trer dans la vanne, donc si la pression est trop \u00e9lev\u00e9e, il n'y a pas beaucoup de place pour arr\u00eater toute r\u00e9sistance. C'est un peu comme casser une brindille au lieu de casser un b\u00e2ton.<\/p>\n\n\n\n

If you encounter a broken gate valve, it is very likely that removal and replacement will be far cheaper than contacting the original manufacturer for internal parts. There are a number of measures that will probably free up a seized gate valve.\r\n\r\n\r\n\r\n\r\n\r\nGET REPAIR GATE VALVE INFORMATION<\/strong><\/a>\r\n\r\n\r\n\r\n\r\nAdvice on Open a Broken Gate Valve<\/h2>\r\n\r\n\r\n\r\n\r\nThe valve does not open and there are several possibilities\r\n\r\n\r\n\r\n\r\n\r\n1\u3001The pipes have not been used for a long time, causing rust inside the valves and preventing them from opening.\r\n\r\n\r\n\r\n\r\n\r\nClose the shut-off valve in front of the valve, remove the valve, check if the gate, stem, and stem nut are rusted and damaged, and replace them with new parts. If not damaged or jammed, clean up the rust and brush on anti-rust oil.\r\n\r\n\r\n\r\n\r\n\r\n2\u3001The pipeline has been used normally and the gate valve is subject to uncertain resistance during the opening.\r\n\r\n\r\n\r\n\r\n\r\nThere are two situations above, one gate valve is stuck by a foreign object in the pipeline, close the valve before shutting off the valve, remove the valve, clean the foreign object, you can continue to use normally. Second, because the artificial switching force is too large, causing the valve stem to bend due to excessive torque, the same need to remove from the valve and replace with the new stem\u3002\r\n\r\n\r\n\r\n\r\n\r\nOpening a broken gate valve is only a temporary recommendation, if it is used for a long time it is recommended that it is replaced gate valve or repair gate valve, but for less expensive gate valves it is recommended that it is replaced.\r\n\r\n\r\n\r\n\r\n\r\nThe following articles are advice on gate valve repair\r\n\r\n\r\n\r\n\r\nHow to Open a Broken Gate Valve?<\/h2>\r\n\r\n\r\n\r\nBefore Working on the Valve<\/h3>\r\n\r\n\r\n\r\n\r\nFirst check that there is water in the pipe: If the utility or well pump is experiencing an issue or the pipe is frozen, the gate valve is not to blame. If the supply is otherwise fine, isolate the gate valve if possible. Closing other valves, or stop-taps, up and downstream could save mess and irritation later. Position a bowl or bucket beneath the valve if possible; otherwise, stuff towels around the area.\r\n\r\n\r\n\r\n\r\nPenetrating Oil<\/h3>\r\n\r\n\r\n\r\n\r\nPenetrating oil usually works to free gate valves that are seized for no other reason than lack of use. The lubricating oil found in almost every home, garage, and workshop in the U.S. is not -- contrary to popular opinion -- a penetrating oil. Its use will do little more than making the gate valve slippery and more difficult to work on. True penetrating oils can be found in auto parts stores and, occasionally, in the auto aisles of department stores. Clean away any verdigris or atmospheric deposits from the gate valve's visible threads, follow the oil manufacturer's directions for use and wait time, then tap the valve gently but firmly with a lightweight hammer to jar free any foreign matter gluing up the threads and try to open it as normal. Use a non-flammable penetrating oil in case the subsequent application of heat is necessary.\r\n\r\n\r\n\r\n\r\nAdditional Leverage<\/h3>\r\n\r\n\r\n\r\n\r\nIf the gate valve is still stuck after using the penetrating oil at least three times, try extending the leverage you have on the handle. Slip a sturdy screwdriver blade through the tines of the handle or use a pair of vise grips on the stem. Support the valve with your free hand so as to prevent the force you apply with the lever from being transferred to the pipe and very gradually increase the pressure until the seize breaks or you fear continuing will bend the pipes on either side of the valve.\r\n\r\n\r\n\r\n\r\nHeat<\/h3>\r\n\r\n\r\n\r\n\r\nHeat is often used to free up two metal components that have become bonded; nuts locked onto bolts by rust are almost certainly the most common use. The idea is to make one component of the valve heat up much faster than the other so that one expands while the other doesn't, causing the unwanted bond to crack. Heating slowly, therefore, does not work. Only an extremely hot flame will work, such as a soldering blow-torch or a welding or cutting torch. Caution must be used to avoid scorching or setting fire to the gate valve's surroundings. Use the heat source judiciously -- do not leave the flame in contact with the valve for so long that any washers catch fire or liquefy and begin to leak -- then apply leveraged pressure immediately.\r\n\r\n\r\n\r\n\r\nHow to Disassemble a Stuck Gate Valve<\/h2>\r\n\r\n\r\n\r\n\r\nate valves are typically screwed to a wall or between two pieces of piping. Before removing it, you can attempt to unclog the valve using just the water in the system. Turn the water source on as high as possible, then slowly open and close the valve as fully as it will let you. This could loosen some debris and allow you to close the gate valve fully.\r\n\r\n\r\n\r\n\r\n\r\nIf this doesn't do the trick, you should turn off the water source and remove the valve from the pipeline. This is typically done by unscrewing the ends. Once the valve is disconnected, use pliers to loosen the gate valve's bonnet, as shown in the picture. Do not loosen the packing nut, as it is what holds the components together that keep fluid from leaking up the stem.\r\n\r\n\r\n\r\n\r\n\r\nWhen you have unscrewed the bonnet, you will be able to remove the top of the gate valve, with the handle and seating, from the body. This will allow you to clean your valve from the top, using a toothbrush or other cleaning tool.\r\n\r\n\r\n\r\n\r\nHow to Rebuilt A Stuck Gate Valve<\/h2>\r\n\r\n\r\n\r\n\r\nCongratulations! Your gate valve is clean and clear! Now all that's left is to put it together. This is a simple process if you have only disconnected the bonnet. Slide the gate back into the proper position in the valve's body then screw the gate valve bonnet until secure. Test the valve by turning the handle. Ensure that the gate opens and closes fully. Once you are sure it is working properly, put it back into its place in the pipeline, using fresh pipe dope or sealant tape.\r\n\r\n\r\n\r\n\r\n\r\nA malfunctioning gate valve is not difficult to repair, but it is even easier to prevent. These problems are typically caused by mineral buildup, so you should fully close and open your gate valves every few months to clear potential problems. If your gate valve has severe pitting or corrosion, you will need to replace it. Luckily, we supply gate valves at the best prices anywhere.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n","parent":0,"count":1,"filter":"raw"},{"term_id":1841,"name":"How to Open a Stuck Ball Valve","slug":"how-to-open-a-stuck-ball-valve","term_group":0,"term_taxonomy_id":1841,"taxonomy":"post_tag","description":"\r\n\r\n\r\n\r\nHOW TO OPEN A STUCK BALL VALVE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\nWhat Causes Stuck Ball Valve<\/a><\/mark><\/strong>?<\/h2>\r\n\r\n\r\n\r\n\r\nOne of the most common types of ball valve failures involves a buildup of dirt and sediment within the valve, making it difficult to open and close. The use of solvent cement glue can also clog up the ball, causing it to stick to the inside of the valve and resist turning. If this happens, you\u2019ll want to take the valve apart and clean out any grime you see.\r\n\r\n\r\n\r\n\r\n\r\nAnother frequent ball valve failure occurs when the elastic used to seal the valve (often in the form of an O-ring) gets worn down over time due to liquid or gas getting pushed through it. Since this is a natural symptom of use, you\u2019ll want to swap out the elastic when you notice cracks or leakage. Turning down the intensity of liquid flowing through the valve can also help extend the lifespan of the O-ring.\r\n\r\n\r\n\r\n\r\n\r\nAs the elastic starts to go, so too does the inner packing of the valve stem. Any scratching or damage to the valve stem requires someone to either replace the stem or the whole valve before the whole thing falls apart.\r\n\r\n\r\n\r\n\r\n\r\nMake sure to look for leak points at the nuts holding the bolts in as well. This indicates that the nuts are too loose or that the end connector needs realignment. Damage to O-rings around the nuts can also prove a culprit of these leaks.\r\n\r\n\r\n\r\n\r\nHow to Open A Stuck Ball Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nBall valves are commonly used valves for main water and various branch shutoffs. This valve functions as an ON\/OFF valve which means that the valve should be either completely open allowing full flow, or completely closed, stopping the entire water flow. Occasionally, it may be necessary to loosen a ball valve because it is stuck or tight, thereby creating an obstruction to fluid flow. If a ball valve won\u2019t open, perform the following steps to rectify the issue:\r\n\r\n\r\n\r\n\r\n\r\n \t- Manual operation<\/li>\r\n \t
- Turn off the main water supply.<\/li>\r\n \t
- Then, loosen the valve by opening and closing it multiple times by turning its handle.<\/li>\r\n \t
- Gently hammer the valve body multiple times on the valve body to break and free up the particles that are trapped between the ball and the valve body.<\/li>\r\n \t
- Gently wiggle and rock the valve handle to help service the ball element and force it to move. Also, try to remove the valve handle and turn the valve a few times using a plier to help it move freely, and place the handle back on the valve using its screw. If these steps don\u2019t work, move on to step 2.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n","parent":0,"count":7,"filter":"raw"},{"term_id":1838,"name":"how to repair a gate valve","slug":"how-to-repair-a-gate-valve","term_group":0,"term_taxonomy_id":1838,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":1835,"name":"how to repair gate valve","slug":"how-to-repair-gate-valve","term_group":0,"term_taxonomy_id":1835,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":1839,"name":"how to replace a gate valve","slug":"how-to-replace-a-gate-valve","term_group":0,"term_taxonomy_id":1839,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":1836,"name":"repair gate valve","slug":"repair-gate-valve","term_group":0,"term_taxonomy_id":1836,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":1833,"name":"replace gate valve with ball valve","slug":"replace-gate-valve-with-ball-valve","term_group":0,"term_taxonomy_id":1833,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":1840,"name":"replacing gate valve","slug":"replacing-gate-valve","term_group":0,"term_taxonomy_id":1840,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":1834,"name":"Stuck Gate Valve","slug":"stuck-gate-valve","term_group":0,"term_taxonomy_id":1834,"taxonomy":"post_tag","description":"\r\n\r\nA gate valve is also called a sluice valve. These valves are used to control the water supply to a water tank. Using the gate valves, the water supply can be turned on and off. A gate valve will be having a hand wheel or an electric motor, a lever, and so on.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nHOW TO OPEN A STUCK GATE VALVE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n
What Causes Stuck Gate Valve<\/a><\/mark><\/strong>?<\/h2>\r\n\r\n\r\n\r\n\r\nA gate valve not closing completely is typically due to sediment that has built up inside the body of the valve. The sediment becomes lodged between the gate that lowers and the inside of the valve body itself. Ball-type valves do not suffer from this problem, as they operate on a different principle than a gate that raises and lowers inside of the valve body.\r\n\r\n\r\n\r\n\r\nGate Valve Stuck Closed<\/h2>\r\n\r\n\r\n\r\n\r\nA gate valve for a property usually has to be closed if plumbing repairs or maintenance are needed inside the building. In some instances, particularly if the main control valve is a gate type valve, the valve may not close completely. In many cases a gate valve repair may be needed. But many times other remedies are available.\r\n\r\n\r\n\r\n\r\nHow to Open a Stuck Gate Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nThe typical reaction when a gate valve will not close fully is to exert additional force on the handle. Using force to close a valve is absolutely the wrong response. Brute force can cause permanent damage to the valve and a loss of water supply to the building. If sediment or mineral deposits are preventing the gate valve from closing fully, there is a more sensible first step to take than brute force.\r\n\r\n\r\n\r\n\r\n\r\nThe first step if a gate valve will not close completely\r\n\r\n\r\n\r\n\r\n\r\nIf sediment or mineral deposits are preventing a gate from closing completely an attempt should be made to flush out the inside of the valve. The proper way to do this is to open a faucet on a sink inside the house so there is a flow of water. Then gently and repeatedly open and close the valve.\r\n\r\n\r\n\r\n\r\n\r\nIf the handle of the valve does not turn freely then loosen the packing nut just above the valve body and around the stem of the valve. Loosening it just one turn should be fine \u2013 just remember to tighten it back up when you are done. Every time you lower the gate some sediment will break free and be flushed away by the water flow. There is absolutely no harm or danger in how many times you do this as long as no excessive force is used.\r\n\r\n\r\n\r\n\r\nHow to Fix a Stuck Gate Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nIf the gate valve becomes jammed or stuck and remains closed, the gate valve stops operating and blocks the water from entering the water tanks. To open a stuck gate value you need to follow the steps suggested below.\r\n\r\n\r\n\r\n\r\n\r\n \t- Step 1: Finding the Valve\r\n
\r\n \t- First, you need to find the valve. Check whether the problem is with the gate valve. A gate valve has the shape of a wedge. The water flows in a straight line in the gate valves. The flow of water is usually stopped by the valve (this acts like a gate). The gate valve does the following functions. When it opens wide, it leaves an opening for water to flow. The opening is of the same size as the pipe which is entering and leaving the valve.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t
- Step 2: Problem Identification\r\n
\r\n \t- Stop the water supply in the valve which is creating the problem. Isolate the area where you are working. This is done to reduce the chances of further leaks. Check whether there are any external factors that are causing the valve to function inappropriately. Reasons may be due to excess cold or a damaged water line. Keep a bucket under the valve which is causing the problem, if it has to be removed and replaced. Some gate valves will not be opened and closed timely. This may affect the operation of the valve.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t
- Step 3: Fixing the Valve\r\n
\r\n \t- A light coat of penetrating oil or 3-in-one oil is applied to the valve and excess oil is wiped off using a waste cloth or rags. The oil must get to the threads. Using the wrench or a hammer, tap the valve and see if the valve opens. On the valve handle, channel locks or an adjustable wrench may be attached. Additional leverage can be achieved by using a rag or gloves that prevent slipping while working. Work in such a way that the surface remains stable. Use a pipe wrench for support so that it does not damage the neighboring pipes. The handle is then warmed by using a hair drier. You can also use a blowtorch if, extreme cold is the cause of the block.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n","parent":0,"count":4,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":1832,"label":"gate valve repair"},{"value":1837,"label":"How to Open a Broken Gate Valve"},{"value":1841,"label":"How to Open a Stuck Ball Valve"},{"value":1838,"label":"how to repair a gate valve"},{"value":1835,"label":"how to repair gate valve"},{"value":1839,"label":"how to replace a gate valve"},{"value":1836,"label":"repair gate valve"},{"value":1833,"label":"replace gate valve with ball valve"},{"value":1840,"label":"replacing gate valve"},{"value":1834,"label":"Stuck Gate Valve"}]},"yoast_head":"\n

Le probl\u00e8me que le robinet-vanne ne peut pas \u00eatre ouvert<\/h3>\n\n\n\n
Si vous avez un robinet-vanne qui ne peut pas \u00eatre ouvert, cela est g\u00e9n\u00e9ralement d\u00fb \u00e0 un axe cass\u00e9. La raison en est g\u00e9n\u00e9ralement que lorsque la vanne est ferm\u00e9e en raison d'une construction non sale, de tartre ou autre, le plombier ou le ma\u00eetre resserrera le filetage, provoquant sa rupture. Si la vanne ne peut pas \u00eatre facilement ferm\u00e9e, il est pr\u00e9f\u00e9rable de remplacer le robinet-vanne pendant la vidange de l'eau, afin d'\u00e9viter davantage les probl\u00e8mes de robinet-vanne et d'entra\u00eener des co\u00fbts suppl\u00e9mentaires.<\/p>\n\n\n\n
Comment remplacer le robinet-vanne sans perdre d'eau chaude<\/h3>\n\n\n\n
La meilleure fa\u00e7on de remplacer la vanne est de geler d\u2019abord le tuyau, puis de remplacer la vanne. La seule autre fa\u00e7on est de fermer le robinet-vanne et de d\u00e9brancher le tuyau inf\u00e9rieur. Une fois que vous avez quitt\u00e9 l'\u00e9crou sup\u00e9rieur du tuyau d'alimentation, vous pouvez changer la vanne tr\u00e8s rapidement. Cela doit \u00eatre fait par un plombier d\u2019urgence qualifi\u00e9.<\/p>\n\n\n\n
Mon robinet-vanne ne ferme pas correctement, pourquoi ?<\/h3>\n\n\n\n
La raison pour laquelle la vanne ne peut pas \u00eatre ferm\u00e9e normalement est qu'\u00e0 mesure que le robinet-vanne vieillit, vous constaterez une accumulation de salet\u00e9 ou de tartre, ce qui emp\u00eachera le m\u00e9canisme de fermeture de se fermer normalement. La meilleure fa\u00e7on de r\u00e9soudre ce probl\u00e8me est de nettoyer soigneusement la vanne ou de remplacer le robinet-vanne.<\/p>\n\n\n\n
Lors du remplacement du robinet-vanne, s'il doit \u00eatre vid\u00e9 en premier<\/h3>\n\n\n\n
Comme expliqu\u00e9 dans le paragraphe pr\u00e9c\u00e9dent, pour remplacer une vanne, il n'est pas toujours n\u00e9cessaire de la vider, \u00e0 condition d'avoir l'exp\u00e9rience et les outils pour le faire.<\/p>\n\n\n\n
Qu'est-ce qui cause la rupture du robinet-vanne<\/h3>\n\n\n\n
La raison de la rupture du robinet-vanne est que la vanne est fragile et que la pression est trop \u00e9lev\u00e9e lorsque le robinet-vanne est ferm\u00e9. Le filetage de la broche n'est pas assez profond pour p\u00e9n\u00e9trer dans la vanne, donc si la pression est trop \u00e9lev\u00e9e, il n'y a pas beaucoup de place pour arr\u00eater toute r\u00e9sistance. C'est un peu comme casser une brindille au lieu de casser un b\u00e2ton.<\/p>\n\n\n\n

Advice on Open a Broken Gate Valve<\/h2>\r\n\r\n\r\n\r\n\r\nThe valve does not open and there are several possibilities\r\n\r\n\r\n\r\n\r\n\r\n1\u3001The pipes have not been used for a long time, causing rust inside the valves and preventing them from opening.\r\n\r\n\r\n\r\n\r\n\r\nClose the shut-off valve in front of the valve, remove the valve, check if the gate, stem, and stem nut are rusted and damaged, and replace them with new parts. If not damaged or jammed, clean up the rust and brush on anti-rust oil.\r\n\r\n\r\n\r\n\r\n\r\n2\u3001The pipeline has been used normally and the gate valve is subject to uncertain resistance during the opening.\r\n\r\n\r\n\r\n\r\n\r\nThere are two situations above, one gate valve is stuck by a foreign object in the pipeline, close the valve before shutting off the valve, remove the valve, clean the foreign object, you can continue to use normally. Second, because the artificial switching force is too large, causing the valve stem to bend due to excessive torque, the same need to remove from the valve and replace with the new stem\u3002\r\n\r\n\r\n\r\n\r\n\r\nOpening a broken gate valve is only a temporary recommendation, if it is used for a long time it is recommended that it is replaced gate valve or repair gate valve, but for less expensive gate valves it is recommended that it is replaced.\r\n\r\n\r\n\r\n\r\n\r\nThe following articles are advice on gate valve repair\r\n\r\n\r\n\r\n\r\n
How to Open a Broken Gate Valve?<\/h2>\r\n\r\n\r\n\r\n
Before Working on the Valve<\/h3>\r\n\r\n\r\n\r\n\r\nFirst check that there is water in the pipe: If the utility or well pump is experiencing an issue or the pipe is frozen, the gate valve is not to blame. If the supply is otherwise fine, isolate the gate valve if possible. Closing other valves, or stop-taps, up and downstream could save mess and irritation later. Position a bowl or bucket beneath the valve if possible; otherwise, stuff towels around the area.\r\n\r\n\r\n\r\n\r\n
Penetrating Oil<\/h3>\r\n\r\n\r\n\r\n\r\nPenetrating oil usually works to free gate valves that are seized for no other reason than lack of use. The lubricating oil found in almost every home, garage, and workshop in the U.S. is not -- contrary to popular opinion -- a penetrating oil. Its use will do little more than making the gate valve slippery and more difficult to work on. True penetrating oils can be found in auto parts stores and, occasionally, in the auto aisles of department stores. Clean away any verdigris or atmospheric deposits from the gate valve's visible threads, follow the oil manufacturer's directions for use and wait time, then tap the valve gently but firmly with a lightweight hammer to jar free any foreign matter gluing up the threads and try to open it as normal. Use a non-flammable penetrating oil in case the subsequent application of heat is necessary.\r\n\r\n\r\n\r\n\r\n
Additional Leverage<\/h3>\r\n\r\n\r\n\r\n\r\nIf the gate valve is still stuck after using the penetrating oil at least three times, try extending the leverage you have on the handle. Slip a sturdy screwdriver blade through the tines of the handle or use a pair of vise grips on the stem. Support the valve with your free hand so as to prevent the force you apply with the lever from being transferred to the pipe and very gradually increase the pressure until the seize breaks or you fear continuing will bend the pipes on either side of the valve.\r\n\r\n\r\n\r\n\r\n
Heat<\/h3>\r\n\r\n\r\n\r\n\r\nHeat is often used to free up two metal components that have become bonded; nuts locked onto bolts by rust are almost certainly the most common use. The idea is to make one component of the valve heat up much faster than the other so that one expands while the other doesn't, causing the unwanted bond to crack. Heating slowly, therefore, does not work. Only an extremely hot flame will work, such as a soldering blow-torch or a welding or cutting torch. Caution must be used to avoid scorching or setting fire to the gate valve's surroundings. Use the heat source judiciously -- do not leave the flame in contact with the valve for so long that any washers catch fire or liquefy and begin to leak -- then apply leveraged pressure immediately.\r\n\r\n\r\n\r\n\r\n
How to Disassemble a Stuck Gate Valve<\/h2>\r\n\r\n\r\n\r\n\r\nate valves are typically screwed to a wall or between two pieces of piping. Before removing it, you can attempt to unclog the valve using just the water in the system. Turn the water source on as high as possible, then slowly open and close the valve as fully as it will let you. This could loosen some debris and allow you to close the gate valve fully.\r\n\r\n\r\n\r\n\r\n\r\nIf this doesn't do the trick, you should turn off the water source and remove the valve from the pipeline. This is typically done by unscrewing the ends. Once the valve is disconnected, use pliers to loosen the gate valve's bonnet, as shown in the picture. Do not loosen the packing nut, as it is what holds the components together that keep fluid from leaking up the stem.\r\n\r\n\r\n\r\n\r\n\r\nWhen you have unscrewed the bonnet, you will be able to remove the top of the gate valve, with the handle and seating, from the body. This will allow you to clean your valve from the top, using a toothbrush or other cleaning tool.\r\n\r\n\r\n\r\n\r\n
How to Rebuilt A Stuck Gate Valve<\/h2>\r\n\r\n\r\n\r\n\r\nCongratulations! Your gate valve is clean and clear! Now all that's left is to put it together. This is a simple process if you have only disconnected the bonnet. Slide the gate back into the proper position in the valve's body then screw the gate valve bonnet until secure. Test the valve by turning the handle. Ensure that the gate opens and closes fully. Once you are sure it is working properly, put it back into its place in the pipeline, using fresh pipe dope or sealant tape.\r\n\r\n\r\n\r\n\r\n\r\nA malfunctioning gate valve is not difficult to repair, but it is even easier to prevent. These problems are typically caused by mineral buildup, so you should fully close and open your gate valves every few months to clear potential problems. If your gate valve has severe pitting or corrosion, you will need to replace it. Luckily, we supply gate valves at the best prices anywhere.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n","parent":0,"count":1,"filter":"raw"},{"term_id":1841,"name":"How to Open a Stuck Ball Valve","slug":"how-to-open-a-stuck-ball-valve","term_group":0,"term_taxonomy_id":1841,"taxonomy":"post_tag","description":"\r\n\r\n\r\n\r\nHOW TO OPEN A STUCK BALL VALVE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n
What Causes Stuck Ball Valve<\/a><\/mark><\/strong>?<\/h2>\r\n\r\n\r\n\r\n\r\nOne of the most common types of ball valve failures involves a buildup of dirt and sediment within the valve, making it difficult to open and close. The use of solvent cement glue can also clog up the ball, causing it to stick to the inside of the valve and resist turning. If this happens, you\u2019ll want to take the valve apart and clean out any grime you see.\r\n\r\n\r\n\r\n\r\n\r\nAnother frequent ball valve failure occurs when the elastic used to seal the valve (often in the form of an O-ring) gets worn down over time due to liquid or gas getting pushed through it. Since this is a natural symptom of use, you\u2019ll want to swap out the elastic when you notice cracks or leakage. Turning down the intensity of liquid flowing through the valve can also help extend the lifespan of the O-ring.\r\n\r\n\r\n\r\n\r\n\r\nAs the elastic starts to go, so too does the inner packing of the valve stem. Any scratching or damage to the valve stem requires someone to either replace the stem or the whole valve before the whole thing falls apart.\r\n\r\n\r\n\r\n\r\n\r\nMake sure to look for leak points at the nuts holding the bolts in as well. This indicates that the nuts are too loose or that the end connector needs realignment. Damage to O-rings around the nuts can also prove a culprit of these leaks.\r\n\r\n\r\n\r\n\r\n
How to Open A Stuck Ball Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nBall valves are commonly used valves for main water and various branch shutoffs. This valve functions as an ON\/OFF valve which means that the valve should be either completely open allowing full flow, or completely closed, stopping the entire water flow. Occasionally, it may be necessary to loosen a ball valve because it is stuck or tight, thereby creating an obstruction to fluid flow. If a ball valve won\u2019t open, perform the following steps to rectify the issue:\r\n\r\n\r\n\r\n\r\n

What Causes Stuck Gate Valve<\/a><\/mark><\/strong>?<\/h2>\r\n\r\n\r\n\r\n\r\nA gate valve not closing completely is typically due to sediment that has built up inside the body of the valve. The sediment becomes lodged between the gate that lowers and the inside of the valve body itself. Ball-type valves do not suffer from this problem, as they operate on a different principle than a gate that raises and lowers inside of the valve body.\r\n\r\n\r\n\r\n\r\n
Gate Valve Stuck Closed<\/h2>\r\n\r\n\r\n\r\n\r\nA gate valve for a property usually has to be closed if plumbing repairs or maintenance are needed inside the building. In some instances, particularly if the main control valve is a gate type valve, the valve may not close completely. In many cases a gate valve repair may be needed. But many times other remedies are available.\r\n\r\n\r\n\r\n\r\n
How to Open a Stuck Gate Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nThe typical reaction when a gate valve will not close fully is to exert additional force on the handle. Using force to close a valve is absolutely the wrong response. Brute force can cause permanent damage to the valve and a loss of water supply to the building. If sediment or mineral deposits are preventing the gate valve from closing fully, there is a more sensible first step to take than brute force.\r\n\r\n\r\n\r\n\r\n\r\nThe first step if a gate valve will not close completely\r\n\r\n\r\n\r\n\r\n\r\nIf sediment or mineral deposits are preventing a gate from closing completely an attempt should be made to flush out the inside of the valve. The proper way to do this is to open a faucet on a sink inside the house so there is a flow of water. Then gently and repeatedly open and close the valve.\r\n\r\n\r\n\r\n\r\n\r\nIf the handle of the valve does not turn freely then loosen the packing nut just above the valve body and around the stem of the valve. Loosening it just one turn should be fine \u2013 just remember to tighten it back up when you are done. Every time you lower the gate some sediment will break free and be flushed away by the water flow. There is absolutely no harm or danger in how many times you do this as long as no excessive force is used.\r\n\r\n\r\n\r\n\r\n
How to Fix a Stuck Gate Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nIf the gate valve becomes jammed or stuck and remains closed, the gate valve stops operating and blocks the water from entering the water tanks. To open a stuck gate value you need to follow the steps suggested below.\r\n\r\n\r\n\r\n\r\n
