Conseils pour ouvrir un robinet-vanne cass\u00e9<\/h2>\r\n\r\n\r\n\r\n\r\nLa valve ne s'ouvre pas et il y a plusieurs possibilit\u00e9s\r\n\r\n\r\n\r\n\r\n\r\n1. Les tuyaux n'ont pas \u00e9t\u00e9 utilis\u00e9s depuis longtemps, ce qui provoque de la rouille \u00e0 l'int\u00e9rieur des vannes et les emp\u00eache de s'ouvrir.\r\n\r\n\r\n\r\n\r\n\r\nFermez le robinet d'arr\u00eat devant la vanne, retirez la vanne, v\u00e9rifiez si le portail, la tige et l'\u00e9crou de tige sont rouill\u00e9s et endommag\u00e9s, et remplacez-les par des pi\u00e8ces neuves. S\u2019il n\u2019est pas endommag\u00e9 ou coinc\u00e9, nettoyez la rouille et appliquez de l\u2019huile antirouille.\r\n\r\n\r\n\r\n\r\n\r\n2. Le pipeline a \u00e9t\u00e9 utilis\u00e9 normalement et le robinet-vanne est soumis \u00e0 une r\u00e9sistance incertaine lors de l'ouverture.\r\n\r\n\r\n\r\n\r\n\r\nIl y a deux situations ci-dessus, un robinet-vanne est coinc\u00e9 par un corps \u00e9tranger dans le pipeline, fermez le robinet avant de fermer le robinet, retirez le robinet, nettoyez le corps \u00e9tranger, vous pouvez continuer \u00e0 utiliser normalement. Deuxi\u00e8mement, parce que la force de commutation artificielle est trop importante, provoquant la flexion de la tige de la vanne en raison d'un couple excessif, il est \u00e9galement n\u00e9cessaire de la retirer de la vanne et de la remplacer par la nouvelle tige.\r\n\r\n\r\n\r\n\r\n\r\nL'ouverture d'un robinet-vanne cass\u00e9 n'est qu'une recommandation temporaire, s'il est utilis\u00e9 pendant une longue p\u00e9riode, il est recommand\u00e9 de le remplacer ou de r\u00e9parer le robinet-vanne, mais pour les robinets-vannes moins chers, il est recommand\u00e9 de le remplacer.\r\n\r\n\r\n\r\n\r\n\r\nLes articles suivants sont des conseils sur la r\u00e9paration des robinets-vannes\r\n\r\n\r\n\r\n\r\n

Comment ouvrir un robinet-vanne cass\u00e9 ?<\/h2>\r\n\r\n\r\n\r\n

Avant de travailler sur la vanne<\/h3>\r\n\r\n\r\n\r\n\r\nV\u00e9rifiez d\u2019abord qu\u2019il y a de l\u2019eau dans le tuyau : si le service public ou la pompe du puits rencontre un probl\u00e8me ou si le tuyau est gel\u00e9, le robinet-vanne n\u2019est pas \u00e0 bl\u00e2mer. Si l\u2019alimentation est par ailleurs bonne, isolez le robinet-vanne si possible. La fermeture d'autres vannes, ou robinets d'arr\u00eat, en amont et en aval pourrait \u00e9viter des d\u00e9g\u00e2ts et des irritations plus tard. Placez un bol ou un seau sous la valve si possible\u00a0; sinon, remplissez les serviettes autour de la zone.\r\n\r\n\r\n\r\n\r\n

Huile p\u00e9n\u00e9trante<\/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

Un effet de levier suppl\u00e9mentaire<\/h3>\r\n\r\n\r\n\r\n\r\nSi le robinet-vanne est toujours bloqu\u00e9 apr\u00e8s avoir utilis\u00e9 l'huile p\u00e9n\u00e9trante au moins trois fois, essayez d'\u00e9tendre l'effet de levier que vous avez sur la poign\u00e9e. Glissez une lame de tournevis robuste dans les dents de la poign\u00e9e ou utilisez une paire de pinces-\u00e9tau sur la tige. Soutenez la vanne avec votre main libre afin d'\u00e9viter que la force que vous appliquez avec le levier ne se transmette au tuyau et augmentez tr\u00e8s progressivement la pression jusqu'\u00e0 ce que le grip se brise ou que vous craigniez de continuer \u00e0 plier les tuyaux de part et d'autre de la vanne.\r\n\r\n\r\n\r\n\r\n

Chaleur<\/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

Comment d\u00e9monter un robinet-vanne bloqu\u00e9<\/h2>\r\n\r\n\r\n\r\n\r\nLes vannes sont g\u00e9n\u00e9ralement viss\u00e9es \u00e0 un mur ou entre deux morceaux de tuyauterie. Avant de le retirer, vous pouvez tenter de d\u00e9boucher la vanne en utilisant uniquement l'eau du syst\u00e8me. Allumez la source d\u2019eau aussi haut que possible, puis ouvrez et fermez lentement la vanne aussi compl\u00e8tement qu\u2019elle vous le permet. Cela pourrait d\u00e9tacher certains d\u00e9bris et vous permettre de fermer compl\u00e8tement le robinet-vanne.\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\nLorsque vous aurez d\u00e9viss\u00e9 le chapeau, vous pourrez retirer le haut du robinet-vanne, avec la poign\u00e9e et le si\u00e8ge, du corps. Cela vous permettra de nettoyer votre valve par le haut, \u00e0 l'aide d'une brosse \u00e0 dents ou autre outil de nettoyage.\r\n\r\n\r\n\r\n\r\n

Comment reconstruire une vanne bloqu\u00e9e<\/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\nUn robinet-vanne d\u00e9fectueux n\u2019est pas difficile \u00e0 r\u00e9parer, mais il est encore plus facile \u00e0 pr\u00e9venir.

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. GET REPAIR GATE VALVE INFORMATION Advice on Open a Broken Gate Valve The valve does not open and there are several possibilities 1\u3001The pipes have not been used for a long time, causing rust inside the valves and preventing them from opening. Close 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. 2\u3001The pipeline has been used normally and the gate valve is subject to uncertain resistance during the opening. There 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 Opening 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. The following articles are advice on gate valve repair How to Open a Broken Gate Valve? Before Working on the Valve First 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. Penetrating Oil Penetrating 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. Additional Leverage If 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. Heat Heat 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. How to Disassemble a Stuck Gate Valve ate 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. If 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. When 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. How to Rebuilt A Stuck Gate Valve Congratulations! 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. A 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.
