Por que as v\u00e1lvulas gaveta falham?<\/h3>\n\n\n\n
As causas mais comuns de falha da v\u00e1lvula gaveta s\u00e3o desgaste e corros\u00e3o da cunha e da sede. As partes internas de uma v\u00e1lvula gaveta tendem a se desgastar com o tempo. E a corros\u00e3o pode fazer com que a cunha fique presa na posi\u00e7\u00e3o aberta ou fechada. Quando o volante \u00e9 tensionado, a haste que vai do volante at\u00e9 a cunha tende a quebrar, inutilizando a v\u00e1lvula.<\/p>\n\n\n\n
Al\u00e9m disso, a gaxeta da haste e a gaxeta do castelo da v\u00e1lvula gaveta s\u00e3o pe\u00e7as de desgaste e precisam ser substitu\u00eddas dentro do prazo recomendado pelo fabricante, o que tamb\u00e9m pode causar vazamento se n\u00e3o for substitu\u00eddo.<\/p>\n\n\n\n
REPARO DE V\u00c1LVULA DE GAVETA<\/h3>\n\n\n\nPosso consertar v\u00e1lvulas gaveta? <\/h3>\n\n\n\n
Sim, consulte os seguintes problemas e solu\u00e7\u00f5es<\/p>\n\n\n\n
1.Problema: Vazamento entre a v\u00e1lvula gaveta e a conex\u00e3o da v\u00e1lvula<\/h4>\n\n\n\n1-1. A\u00e7\u00e3o Corretiva:<\/h4>\n\n\n\n
Primeiro, verifique se os parafusos que conectam a v\u00e1lvula \u00e0 v\u00e1lvula gaveta est\u00e3o apertados; caso contr\u00e1rio, o anel de veda\u00e7\u00e3o e a superf\u00edcie da ranhura de veda\u00e7\u00e3o do flange geralmente levam a vazamentos se n\u00e3o estiverem suficientemente conectados. Verifique se os parafusos e porcas est\u00e3o em ordem e aperte todos os parafusos at\u00e9 que a veda\u00e7\u00e3o seja pressionada. Em seguida, verifique o tamanho e a precis\u00e3o da veda\u00e7\u00e3o e da superf\u00edcie da ranhura de veda\u00e7\u00e3o do flange. Se a superf\u00edcie de contato da veda\u00e7\u00e3o for do tamanho errado ou muito \u00e1spera, repare-a ou substitua-a. Verifique tamb\u00e9m a superf\u00edcie de contato do anel de veda\u00e7\u00e3o e da ranhura de veda\u00e7\u00e3o do flange quanto a defeitos como um pouco de eros\u00e3o, buracos de areia, buracos de areia ou impurezas; em caso afirmativo, solde, repare ou limpe adequadamente.<\/p>\n\n\n\n
2.Problema: Vazamento do cap\u00f4<\/h4>\n\n\n\n
Este fen\u00f4meno de falha ocorre frequentemente no vazamento da veda\u00e7\u00e3o da gaxeta.<\/p>\n\n\n\n
2-1. A\u00e7\u00e3o Corretiva:<\/h4>\n\n\n\n
Em primeiro lugar, verifique se a veda\u00e7\u00e3o se ajusta corretamente e \u00e9 compat\u00edvel com a ranhura da veda\u00e7\u00e3o; se houver algum problema, a veda\u00e7\u00e3o deve ser substitu\u00edda ou a ranhura da veda\u00e7\u00e3o reparada. Em segundo lugar, verifique se a veda\u00e7\u00e3o apresenta rebarbas, quebras e tor\u00e7\u00f5es; nesse caso, a veda\u00e7\u00e3o deve ser substitu\u00edda. Em seguida, verifique se h\u00e1 rugosidade ou outros defeitos na superf\u00edcie da ranhura de veda\u00e7\u00e3o e, se houver defeitos, remova-os ou substitua as pe\u00e7as danificadas.<\/p>\n\n\n\n
Quando a tampa ou suporte utilizar gaxeta de veda\u00e7\u00e3o de compress\u00e3o, a instala\u00e7\u00e3o da gaxeta deve ser verificada e se a gaxeta estiver instalada ao contr\u00e1rio, ela deve ser removida e instalada de acordo com o m\u00e9todo correto.<\/p>\n\n\n\n
3.Problema: Vazamento da cavidade do corpo da v\u00e1lvula<\/h4>\n\n\n\n
Durante o processo de fundi\u00e7\u00e3o, \u00e0s vezes podem aparecer defeitos de fundi\u00e7\u00e3o no corpo da v\u00e1lvula, como furos de areia e furos de areia. Eles s\u00e3o dif\u00edceis de detectar durante a usinagem sem a necessidade de testes n\u00e3o destrutivos, mas quando a press\u00e3o \u00e9 aplicada ao corpo da v\u00e1lvula, defeitos ocultos de fundi\u00e7\u00e3o s\u00e3o expostos.<\/p>\n\n\n\n
3-1. A\u00e7\u00e3o Corretiva:<\/h4>\n\n\n\n
Se for este o caso, pode ser soldado, reparado ou renovado conforme apropriado de acordo com a norma.<\/p>\n\n\n\n
4.Problema: Vazamento da sede da v\u00e1lvula e da cunha da v\u00e1lvula<\/h4>\n\n\n\n
4.1 Ocorre vazamento na sede da v\u00e1lvula e na cunha da v\u00e1lvula, fen\u00f4meno mais comum durante a instala\u00e7\u00e3o ou manuten\u00e7\u00e3o de v\u00e1lvulas gaveta. Geralmente existem dois tipos: um \u00e9 o vazamento na superf\u00edcie de veda\u00e7\u00e3o; o outro \u00e9 o vazamento na raiz de veda\u00e7\u00e3o.<\/p>\n\n\n\n
4.1-1.A\u00e7\u00e3o Corretiva: A primeira coisa a verificar \u00e9 a precis\u00e3o da superf\u00edcie de contato de veda\u00e7\u00e3o da sede da v\u00e1lvula e da cunha da v\u00e1lvula. A superf\u00edcie de veda\u00e7\u00e3o precisa ser retificada e, se houver uma superf\u00edcie \u00e1spera, remova-a e reafie-a. Em seguida, verifique se h\u00e1 defeitos na superf\u00edcie de veda\u00e7\u00e3o, como marcas, reentr\u00e2ncias, buracos, rachaduras, etc. Se for esse o caso, a sede e a cunha devem ser substitu\u00eddas. Para sedes de v\u00e1lvulas com molas de compress\u00e3o, verifique se a for\u00e7a da mola de press\u00e3o atende aos requisitos; se a for\u00e7a da mola for baixa, a mola de compress\u00e3o deve ser substitu\u00edda. Al\u00e9m disso, verifique se o acoplamento em forma de T entre a cunha da v\u00e1lvula e a haste n\u00e3o est\u00e1 muito frouxo e se n\u00e3o h\u00e1 inclina\u00e7\u00e3o; nesse caso, a cunha deve ser removida e ajustada no tamanho ideal.<\/p>\n\n\n\n
4.2 Ao instalar a v\u00e1lvula, \u00e9 f\u00e1cil deixar cair objetos estranhos, como verifica\u00e7\u00f5es de soldagem, sucata e impurezas.<\/p>\n\n\n\n
4.2-1.A\u00e7\u00e3o corretiva: Limpe os detritos antes da instala\u00e7\u00e3o. Se voc\u00ea esquecer de limpar ou limpar de forma incompleta, a cunha da v\u00e1lvula n\u00e3o atingir\u00e1 a profundidade de fechamento desejada e causar\u00e1 vazamento, caso em que o corpo da v\u00e1lvula dever\u00e1 ser removido e limpo.<\/p>\n\n\n\n
A sede da v\u00e1lvula deve ser instalada com uma ferramenta especial. Verifique se a sede da v\u00e1lvula est\u00e1 instalada corretamente, se as roscas forem menos profundas do que o esperado a sede ir\u00e1 vazar, neste caso a sede dever\u00e1 ser instalada utilizando uma ferramenta especial.<\/p>\n\n\n\n
Como voc\u00ea conserta uma v\u00e1lvula gaveta que n\u00e3o abre ou fecha?<\/h3>\n\n\n\n
A primeira possibilidade \u00e9 que o torque da v\u00e1lvula seja muito grande e exija mais for\u00e7a para fechar ou abrir, substitua o atuador por um tamanho maior<\/p>\n\n\n\n
A segunda possibilidade \u00e9 que, quando a v\u00e1lvula \u00e9 instalada na tubula\u00e7\u00e3o, haja um ac\u00famulo de esc\u00f3ria de soldagem ou detritos na parte inferior da v\u00e1lvula bloqueando o fechamento da comporta, e os detritos precisam ser removidos. A terceira possibilidade \u00e9 que a comporta e a sede da v\u00e1lvula tenham sido danificadas e precisem ser reparadas e substitu\u00eddas a tempo.<\/p>\n\n\n\n
Consulte especificamente a se\u00e7\u00e3o 4.<\/p>\n\n\n\n
Como substituir uma v\u00e1lvula gaveta, Substitua a v\u00e1lvula gaveta por uma v\u00e1lvula esf\u00e9rica<\/h3>\n\n\n\n
Feche a v\u00e1lvula de corte na frente para que o meio fique em estado est\u00e1tico, e descarregue o meio nesta se\u00e7\u00e3o da tubula\u00e7\u00e3o, se for uma v\u00e1lvula gaveta conectada por flange, \u00e9 necess\u00e1rio remover o parafuso e a porca da conex\u00e3o , limpe a superf\u00edcie de veda\u00e7\u00e3o, substitua a junta e reconecte a nova v\u00e1lvula esf\u00e9rica. Se for uma v\u00e1lvula gaveta com conex\u00e3o roscada, basta parafus\u00e1-la. No caso de conex\u00f5es SW ou BW, corte e solde a nova v\u00e1lvula esf\u00e9rica no lugar.<\/p>\n\n\n\n
V\u00e1lvula de gaveta de \u00e1gua<\/mark><\/strong><\/a> Problemas<\/h2>\n\n\n\nMinha v\u00e1lvula gaveta est\u00e1 presa e aberta, o que devo fazer<\/h3>\n\n\n\n
Se seu v\u00e1lvula de gaveta<\/strong> est\u00e1 aberto e voc\u00ea n\u00e3o pode fech\u00e1-lo, ent\u00e3o a \u00fanica op\u00e7\u00e3o \u00e9 dren\u00e1-lo. Em alguns casos, os encanadores podem substituir as v\u00e1lvulas rapidamente, mas isso n\u00e3o representa um risco. Na maioria dos casos, quando a v\u00e1lvula gaveta apresenta um problema, se a v\u00e1lvula estiver aberta, \u00e9 melhor drenar a \u00e1gua.<\/p>\n\n\n\nO problema de que a v\u00e1lvula gaveta n\u00e3o pode ser aberta<\/h3>\n\n\n\n
Se voc\u00ea tiver uma v\u00e1lvula gaveta que n\u00e3o pode ser aberta, geralmente \u00e9 devido a um fuso quebrado. A raz\u00e3o para esse descanso geralmente \u00e9 que quando a v\u00e1lvula \u00e9 fechada por n\u00e3o estar suja, incrusta\u00e7\u00e3o ou outro, o encanador ou mestre ir\u00e1 apertar a rosca fazendo com que ela se quebre. Se a v\u00e1lvula n\u00e3o puder ser fechada facilmente, \u00e9 melhor substituir a v\u00e1lvula gaveta durante a drenagem da \u00e1gua, para evitar problemas na v\u00e1lvula gaveta e causar mais custos.<\/p>\n\n\n\n
Como substituir a v\u00e1lvula gaveta sem perder \u00e1gua quente<\/h3>\n\n\n\n
A melhor maneira de substituir a v\u00e1lvula \u00e9 congelar primeiro o tubo e depois substituir a v\u00e1lvula. A \u00fanica outra maneira \u00e9 fechar a v\u00e1lvula gaveta e desconectar o tubo inferior. Depois de deixar a porca superior do tubo de alimenta\u00e7\u00e3o, voc\u00ea pode trocar a v\u00e1lvula muito rapidamente. Isso deve ser feito por um encanador de emerg\u00eancia qualificado.<\/p>\n\n\n\n
Minha v\u00e1lvula gaveta n\u00e3o fecha corretamente, por qu\u00ea?<\/h3>\n\n\n\n
A raz\u00e3o pela qual a v\u00e1lvula n\u00e3o pode ser fechada normalmente \u00e9 que, \u00e0 medida que a v\u00e1lvula gaveta envelhece, voc\u00ea encontrar\u00e1 sujeira ou ac\u00famulo de incrusta\u00e7\u00f5es, fazendo com que o mecanismo de fechamento n\u00e3o feche normalmente. A melhor maneira de resolver este problema \u00e9 limpar completamente a v\u00e1lvula ou substituir a v\u00e1lvula gaveta.<\/p>\n\n\n\n
Ao substituir a v\u00e1lvula gaveta, se ela deve ser esvaziada primeiro<\/h3>\n\n\n\n
Conforme explicado no par\u00e1grafo anterior, para substituir qualquer v\u00e1lvula nem sempre \u00e9 necess\u00e1rio esvazi\u00e1-la, desde que tenha experi\u00eancia e ferramentas para faz\u00ea-lo.<\/p>\n\n\n\n
O que causa a ruptura da v\u00e1lvula gaveta<\/h3>\n\n\n\n
O motivo da ruptura da v\u00e1lvula gaveta \u00e9 que a v\u00e1lvula \u00e9 fr\u00e1gil e a press\u00e3o \u00e9 muito alta quando a v\u00e1lvula gaveta est\u00e1 fechada. A rosca do fuso n\u00e3o \u00e9 profunda o suficiente para entrar na v\u00e1lvula, portanto, se a press\u00e3o for muito grande, n\u00e3o haver\u00e1 muito espa\u00e7o para impedir qualquer resist\u00eancia. \u00c9 como quebrar um galho em vez de quebrar um graveto.<\/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

O problema de que a v\u00e1lvula gaveta n\u00e3o pode ser aberta<\/h3>\n\n\n\n
Se voc\u00ea tiver uma v\u00e1lvula gaveta que n\u00e3o pode ser aberta, geralmente \u00e9 devido a um fuso quebrado. A raz\u00e3o para esse descanso geralmente \u00e9 que quando a v\u00e1lvula \u00e9 fechada por n\u00e3o estar suja, incrusta\u00e7\u00e3o ou outro, o encanador ou mestre ir\u00e1 apertar a rosca fazendo com que ela se quebre. Se a v\u00e1lvula n\u00e3o puder ser fechada facilmente, \u00e9 melhor substituir a v\u00e1lvula gaveta durante a drenagem da \u00e1gua, para evitar problemas na v\u00e1lvula gaveta e causar mais custos.<\/p>\n\n\n\n
Como substituir a v\u00e1lvula gaveta sem perder \u00e1gua quente<\/h3>\n\n\n\n
A melhor maneira de substituir a v\u00e1lvula \u00e9 congelar primeiro o tubo e depois substituir a v\u00e1lvula. A \u00fanica outra maneira \u00e9 fechar a v\u00e1lvula gaveta e desconectar o tubo inferior. Depois de deixar a porca superior do tubo de alimenta\u00e7\u00e3o, voc\u00ea pode trocar a v\u00e1lvula muito rapidamente. Isso deve ser feito por um encanador de emerg\u00eancia qualificado.<\/p>\n\n\n\n
Minha v\u00e1lvula gaveta n\u00e3o fecha corretamente, por qu\u00ea?<\/h3>\n\n\n\n
A raz\u00e3o pela qual a v\u00e1lvula n\u00e3o pode ser fechada normalmente \u00e9 que, \u00e0 medida que a v\u00e1lvula gaveta envelhece, voc\u00ea encontrar\u00e1 sujeira ou ac\u00famulo de incrusta\u00e7\u00f5es, fazendo com que o mecanismo de fechamento n\u00e3o feche normalmente. A melhor maneira de resolver este problema \u00e9 limpar completamente a v\u00e1lvula ou substituir a v\u00e1lvula gaveta.<\/p>\n\n\n\n
Ao substituir a v\u00e1lvula gaveta, se ela deve ser esvaziada primeiro<\/h3>\n\n\n\n
Conforme explicado no par\u00e1grafo anterior, para substituir qualquer v\u00e1lvula nem sempre \u00e9 necess\u00e1rio esvazi\u00e1-la, desde que tenha experi\u00eancia e ferramentas para faz\u00ea-lo.<\/p>\n\n\n\n
O que causa a ruptura da v\u00e1lvula gaveta<\/h3>\n\n\n\n
O motivo da ruptura da v\u00e1lvula gaveta \u00e9 que a v\u00e1lvula \u00e9 fr\u00e1gil e a press\u00e3o \u00e9 muito alta quando a v\u00e1lvula gaveta est\u00e1 fechada. A rosca do fuso n\u00e3o \u00e9 profunda o suficiente para entrar na v\u00e1lvula, portanto, se a press\u00e3o for muito grande, n\u00e3o haver\u00e1 muito espa\u00e7o para impedir qualquer resist\u00eancia. \u00c9 como quebrar um galho em vez de quebrar um graveto.<\/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
