\u00bfPor qu\u00e9 fallan las v\u00e1lvulas de compuerta?<\/h3>\n\n\n\n
Las causas m\u00e1s comunes de falla de una v\u00e1lvula de compuerta son el desgaste y la corrosi\u00f3n de la cu\u00f1a y el asiento. Las partes internas de una v\u00e1lvula de compuerta tienden a desgastarse con el tiempo. Y la corrosi\u00f3n puede hacer que la cu\u00f1a se atasque en la posici\u00f3n abierta o cerrada. Cuando se tensiona el volante, el v\u00e1stago que va del volante a la cu\u00f1a tiende a romperse, inutilizando la v\u00e1lvula.<\/p>\n\n\n\n
Adem\u00e1s, la empaquetadura del v\u00e1stago y la junta del casquete de la v\u00e1lvula de compuerta son piezas de desgaste y deben reemplazarse dentro del per\u00edodo recomendado por el fabricante, lo que tambi\u00e9n puede causar fugas si no se reemplazan.<\/p>\n\n\n\n
REPARACI\u00d3N DE V\u00c1LVULA DE COMPUERTA<\/h3>\n\n\n\n\u00bfPuedo reparar v\u00e1lvulas de compuerta? <\/h3>\n\n\n\n
S\u00ed, consulte los siguientes problemas y soluciones.<\/p>\n\n\n\n
1.Problema: Fuga entre la v\u00e1lvula de compuerta y la conexi\u00f3n de la v\u00e1lvula<\/h4>\n\n\n\n1-1.Acci\u00f3n Correctiva:<\/h4>\n\n\n\n
Primero, verifique si los pernos que conectan la v\u00e1lvula a la v\u00e1lvula de compuerta est\u00e1n apretados; de lo contrario, el anillo de sellado y la superficie de la ranura de sellado de la brida a menudo provocan fugas si no est\u00e1n suficientemente conectados. Verifique que los pernos y tuercas est\u00e9n en orden y apriete todos los pernos hasta presionar el sello. A continuaci\u00f3n, verifique el tama\u00f1o y la precisi\u00f3n de la superficie de la ranura de sellado del sello y de la brida; si la superficie de contacto del sello es del tama\u00f1o incorrecto o demasiado rugosa, rep\u00e1rela o renu\u00e9vela. Tambi\u00e9n verifique la superficie de contacto del anillo de sello y la ranura de sellado de la brida para detectar defectos como un poco de erosi\u00f3n, agujeros de arena, agujeros de arena o impurezas; de ser as\u00ed, suelde, repare o limpie en consecuencia.<\/p>\n\n\n\n
2.Problema: Fuga del cap\u00f3<\/h4>\n\n\n\n
Este fen\u00f3meno de falla ocurre a menudo en la fuga del sello del empaque.<\/p>\n\n\n\n
2-1.Acci\u00f3n Correctiva:<\/h4>\n\n\n\n
En primer lugar, comprobar que el sello encaje correctamente y sea compatible con la ranura del sello, si hay alg\u00fan problema se debe reemplazar el sello o reparar la ranura del sello. En segundo lugar, verifique si el sello tiene rebabas, se rompe o se tuerce; de ser as\u00ed, se debe reemplazar el sello. Luego, verifique la superficie de la ranura del sello en busca de asperezas u otros defectos y, si los hay, elim\u00ednelos o renueve las piezas da\u00f1adas.<\/p>\n\n\n\n
Cuando el bonete o el soporte utilizan empaquetadura de sellado de compresi\u00f3n, se debe verificar la instalaci\u00f3n del empaque y, si se encuentra que el empaque est\u00e1 instalado al rev\u00e9s, se debe retirar e instalar de acuerdo con el m\u00e9todo correcto.<\/p>\n\n\n\n
3.Problema: Fuga de la cavidad del cuerpo de la v\u00e1lvula<\/h4>\n\n\n\n
Durante el proceso de fundici\u00f3n, a veces pueden aparecer defectos de fundici\u00f3n en el cuerpo de la v\u00e1lvula, como agujeros de arena y arena. Son dif\u00edciles de detectar durante el mecanizado sin el requisito de pruebas no destructivas, pero una vez que se aplica presi\u00f3n al cuerpo de la v\u00e1lvula, los defectos de fundici\u00f3n ocultos quedan expuestos.<\/p>\n\n\n\n
3-1.Acci\u00f3n Correctiva:<\/h4>\n\n\n\n
Si este es el caso, se puede soldar, reparar o renovar seg\u00fan corresponda seg\u00fan la norma.<\/p>\n\n\n\n
4.Problema: Fuga desde el asiento de la v\u00e1lvula y la cu\u00f1a de la v\u00e1lvula<\/h4>\n\n\n\n
4.1 Se producen fugas en el asiento de la v\u00e1lvula y en la cu\u00f1a de la v\u00e1lvula, que es el fen\u00f3meno m\u00e1s com\u00fan durante la instalaci\u00f3n o el mantenimiento de v\u00e1lvulas de compuerta. Generalmente hay dos tipos: uno es la fuga en la superficie de sellado; el otro es una fuga en la ra\u00edz de sellado.<\/p>\n\n\n\n
4.1-1.Acci\u00f3n correctiva: Lo primero que se debe verificar es la precisi\u00f3n de la superficie de contacto de sellado del asiento de la v\u00e1lvula y la cu\u00f1a de la v\u00e1lvula. La superficie de sellado debe pulirse y, si hay una superficie rugosa, quitarla y volver a pulirse. A continuaci\u00f3n, revise la superficie de sellado en busca de defectos como picaduras, hendiduras, agujeros de arena, grietas, etc. Si este es el caso, se deben reemplazar el asiento y la cu\u00f1a. Para asientos de v\u00e1lvula con resortes de compresi\u00f3n, verifique que la fuerza del resorte del resorte de presi\u00f3n cumpla con los requisitos; si la fuerza del resorte es baja, se debe reemplazar el resorte de compresi\u00f3n. Adem\u00e1s, comprobar que el acoplamiento en forma de T entre la cu\u00f1a de la v\u00e1lvula y el v\u00e1stago no est\u00e9 demasiado flojo y que no tenga pendiente, en caso afirmativo se deber\u00e1 retirar la cu\u00f1a y ajustarla al tama\u00f1o \u00f3ptimo.<\/p>\n\n\n\n
4.2 Al instalar la v\u00e1lvula, es f\u00e1cil que caigan objetos extra\u00f1os como controles de soldadura, chatarra e impurezas.<\/p>\n\n\n\n
4.2-1.Acci\u00f3n correctiva: Limpie los residuos antes de la instalaci\u00f3n. Si olvida limpiar o no limpia por completo, la cu\u00f1a de la v\u00e1lvula no alcanzar\u00e1 la profundidad de cierre deseada y provocar\u00e1 fugas, en cuyo caso se debe retirar y limpiar el cuerpo de la v\u00e1lvula.<\/p>\n\n\n\n
El asiento de la v\u00e1lvula debe instalarse utilizando una herramienta especial. Verifique que el asiento de la v\u00e1lvula est\u00e9 instalado correctamente, si las roscas son menos profundas de lo esperado el asiento tendr\u00e1 fugas, en este caso, el asiento debe instalarse usando una herramienta especial.<\/p>\n\n\n\n
\u00bfC\u00f3mo se arregla una v\u00e1lvula de compuerta que no se abre ni se cierra?<\/h3>\n\n\n\n
La primera posibilidad es que el torque de la v\u00e1lvula sea demasiado grande y requiera m\u00e1s fuerza para cerrar o abrir, reemplace el actuador por uno de mayor tama\u00f1o.<\/p>\n\n\n\n
La segunda posibilidad es que, cuando la v\u00e1lvula se instala en la tuber\u00eda, haya una acumulaci\u00f3n de escoria o desechos de soldadura en la parte inferior de la v\u00e1lvula que bloquea el cierre de la compuerta y es necesario eliminar los desechos. La tercera posibilidad es que la compuerta y el asiento de la v\u00e1lvula se hayan da\u00f1ado y deban repararse y reemplazarse a tiempo.<\/p>\n\n\n\n
Consulte espec\u00edficamente la secci\u00f3n 4.<\/p>\n\n\n\n
C\u00f3mo reemplazar una v\u00e1lvula de compuerta, Reemplazar la v\u00e1lvula de compuerta con una v\u00e1lvula de bola<\/h3>\n\n\n\n
Cierre la v\u00e1lvula de cierre en el frente para que el medio est\u00e9 en estado est\u00e1tico y descargue el medio en esta secci\u00f3n de la tuber\u00eda; si es una v\u00e1lvula de compuerta conectada con brida, debe quitar el perno y la tuerca de la conexi\u00f3n. , limpie la superficie de sellado, reemplace la junta y vuelva a conectar la nueva v\u00e1lvula de bola. Si se trata de una v\u00e1lvula de compuerta con conexi\u00f3n roscada, simplemente atorn\u00edllela. En el caso de conexiones SW o BW, corte y suelde la nueva v\u00e1lvula de bola en su lugar.<\/p>\n\n\n\n
V\u00e1lvula de compuerta de agua<\/mark><\/strong><\/a> Problemas<\/h2>\n\n\n\nMi v\u00e1lvula de compuerta est\u00e1 atascada y abierta, \u00bfqu\u00e9 debo hacer?<\/h3>\n\n\n\n
Si tu v\u00e1lvula de compuerta<\/strong> est\u00e1 abierto y no puedes cerrarlo, entonces la \u00fanica opci\u00f3n es drenarlo. En algunos casos, los fontaneros pueden sustituir las v\u00e1lvulas r\u00e1pidamente, pero esto no supone ning\u00fan riesgo. En la mayor\u00eda de los casos, cuando la v\u00e1lvula de compuerta tiene un problema, si la v\u00e1lvula de compuerta est\u00e1 abierta, es mejor drenar el agua.<\/p>\n\n\n\nEl problema de que la v\u00e1lvula de compuerta no se puede abrir.<\/h3>\n\n\n\n
Si tiene una v\u00e1lvula de compuerta que no se puede abrir, generalmente se debe a un eje roto. La raz\u00f3n de este descanso general es que cuando la v\u00e1lvula est\u00e1 cerrada debido a una construcci\u00f3n no sucia, incrustaciones u otros, el plomero o el maestro apretar\u00e1n la rosca provocando que se rompa. Si la v\u00e1lvula no se puede cerrar f\u00e1cilmente, es mejor reemplazar la v\u00e1lvula de compuerta mientras se drena el agua, para evitar a\u00fan m\u00e1s problemas con la v\u00e1lvula de compuerta y generar m\u00e1s costos.<\/p>\n\n\n\n
C\u00f3mo reemplazar la v\u00e1lvula de compuerta sin perder agua caliente<\/h3>\n\n\n\n
La mejor manera de reemplazar la v\u00e1lvula es congelar primero la tuber\u00eda y luego reemplazar la v\u00e1lvula. La \u00fanica otra forma es cerrar la v\u00e1lvula de compuerta y desconectar el tubo inferior. Una vez que dejes la tuerca superior de la tuber\u00eda de suministro, podr\u00e1s cambiar la v\u00e1lvula muy r\u00e1pidamente. Esto debe hacerlo un fontanero de emergencia cualificado.<\/p>\n\n\n\n
Mi v\u00e1lvula de compuerta no puede cerrar correctamente, \u00bfpor qu\u00e9?<\/h3>\n\n\n\n
La raz\u00f3n por la que la v\u00e1lvula no se puede cerrar normalmente es que a medida que la v\u00e1lvula de compuerta envejece, encontrar\u00e1 acumulaci\u00f3n de suciedad o sarro, lo que provocar\u00e1 que el mecanismo de cierre no cierre normalmente. La mejor manera de resolver este problema es limpiar minuciosamente la v\u00e1lvula o reemplazar la v\u00e1lvula de compuerta.<\/p>\n\n\n\n
Al reemplazar la v\u00e1lvula de compuerta, si se debe vaciar primero<\/h3>\n\n\n\n
Como se explica en el p\u00e1rrafo anterior, para sustituir cualquier v\u00e1lvula no siempre es necesario vaciarla, siempre y cuando se tenga la experiencia y las herramientas para hacerlo.<\/p>\n\n\n\n
\u00bfQu\u00e9 causa que la v\u00e1lvula de compuerta se rompa?<\/h3>\n\n\n\n
El motivo de la rotura de la v\u00e1lvula de compuerta es que la v\u00e1lvula es fr\u00e1gil y la presi\u00f3n es demasiado alta cuando la v\u00e1lvula de compuerta est\u00e1 cerrada. La rosca del husillo no es lo suficientemente profunda para entrar en la v\u00e1lvula, por lo que si la presi\u00f3n es demasiado grande, no hay mucho espacio para detener cualquier resistencia. Es un poco como romper una ramita en lugar de romper un palo.<\/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

El problema de que la v\u00e1lvula de compuerta no se puede abrir.<\/h3>\n\n\n\n
Si tiene una v\u00e1lvula de compuerta que no se puede abrir, generalmente se debe a un eje roto. La raz\u00f3n de este descanso general es que cuando la v\u00e1lvula est\u00e1 cerrada debido a una construcci\u00f3n no sucia, incrustaciones u otros, el plomero o el maestro apretar\u00e1n la rosca provocando que se rompa. Si la v\u00e1lvula no se puede cerrar f\u00e1cilmente, es mejor reemplazar la v\u00e1lvula de compuerta mientras se drena el agua, para evitar a\u00fan m\u00e1s problemas con la v\u00e1lvula de compuerta y generar m\u00e1s costos.<\/p>\n\n\n\n
C\u00f3mo reemplazar la v\u00e1lvula de compuerta sin perder agua caliente<\/h3>\n\n\n\n
La mejor manera de reemplazar la v\u00e1lvula es congelar primero la tuber\u00eda y luego reemplazar la v\u00e1lvula. La \u00fanica otra forma es cerrar la v\u00e1lvula de compuerta y desconectar el tubo inferior. Una vez que dejes la tuerca superior de la tuber\u00eda de suministro, podr\u00e1s cambiar la v\u00e1lvula muy r\u00e1pidamente. Esto debe hacerlo un fontanero de emergencia cualificado.<\/p>\n\n\n\n
Mi v\u00e1lvula de compuerta no puede cerrar correctamente, \u00bfpor qu\u00e9?<\/h3>\n\n\n\n
La raz\u00f3n por la que la v\u00e1lvula no se puede cerrar normalmente es que a medida que la v\u00e1lvula de compuerta envejece, encontrar\u00e1 acumulaci\u00f3n de suciedad o sarro, lo que provocar\u00e1 que el mecanismo de cierre no cierre normalmente. La mejor manera de resolver este problema es limpiar minuciosamente la v\u00e1lvula o reemplazar la v\u00e1lvula de compuerta.<\/p>\n\n\n\n
Al reemplazar la v\u00e1lvula de compuerta, si se debe vaciar primero<\/h3>\n\n\n\n
Como se explica en el p\u00e1rrafo anterior, para sustituir cualquier v\u00e1lvula no siempre es necesario vaciarla, siempre y cuando se tenga la experiencia y las herramientas para hacerlo.<\/p>\n\n\n\n
\u00bfQu\u00e9 causa que la v\u00e1lvula de compuerta se rompa?<\/h3>\n\n\n\n
El motivo de la rotura de la v\u00e1lvula de compuerta es que la v\u00e1lvula es fr\u00e1gil y la presi\u00f3n es demasiado alta cuando la v\u00e1lvula de compuerta est\u00e1 cerrada. La rosca del husillo no es lo suficientemente profunda para entrar en la v\u00e1lvula, por lo que si la presi\u00f3n es demasiado grande, no hay mucho espacio para detener cualquier resistencia. Es un poco como romper una ramita en lugar de romper un palo.<\/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
