Warum versagen Absperrschieber?<\/h3>\n\n\n\n
Die h\u00e4ufigsten Ursachen f\u00fcr den Ausfall von Schieberventilen sind Verschlei\u00df und Korrosion des Keils und des Ventilsitzes. Die inneren Teile eines Schieberventils neigen dazu, mit der Zeit zu verschlei\u00dfen. Und Korrosion kann dazu f\u00fchren, dass der Keil in der offenen oder geschlossenen Position h\u00e4ngen bleibt. Wenn das Handrad belastet wird, neigt die Spindel, die vom Handrad zum Keil f\u00fchrt, dazu, abzubrechen, wodurch das Ventil unbrauchbar wird.<\/p>\n\n\n\n
Dar\u00fcber hinaus sind die Spindelpackung und die Deckeldichtung im Absperrschieber Verschlei\u00dfteile und m\u00fcssen innerhalb der vom Hersteller empfohlenen Zeitspanne ausgetauscht werden. Wenn sie nicht ausgetauscht werden, kann es ebenfalls zu Undichtigkeiten kommen.<\/p>\n\n\n\n
SCHIEBERREPARATUR<\/h3>\n\n\n\nKann ich Schieber reparieren? <\/h3>\n\n\n\n
Ja, bitte beachten Sie die folgenden Probleme und L\u00f6sungen<\/p>\n\n\n\n
1.Problem: Leckage zwischen Schieber und Ventilanschluss<\/h4>\n\n\n\n1-1.Korrekturma\u00dfnahme:<\/h4>\n\n\n\n
\u00dcberpr\u00fcfen Sie zun\u00e4chst, ob die Schrauben, die das Ventil mit dem Schieber verbinden, fest sitzen. Wenn nicht, kommt es bei unzureichender Verbindung h\u00e4ufig zu Undichtigkeiten an Dichtungsring und Flanschdichtungsnut. \u00dcberpr\u00fcfen Sie, ob Schrauben und Muttern in Ordnung sind, und ziehen Sie alle Schrauben fest, bis die Dichtung fest sitzt. \u00dcberpr\u00fcfen Sie als N\u00e4chstes die Gr\u00f6\u00dfe und Genauigkeit der Dichtungs- und Flanschdichtungsnutoberfl\u00e4che. Wenn die Dichtungskontaktfl\u00e4che die falsche Gr\u00f6\u00dfe hat oder zu rau ist, reparieren oder erneuern Sie sie. \u00dcberpr\u00fcfen Sie auch die Kontaktfl\u00e4che des Dichtungsrings und der Flanschdichtungsnut auf Defekte wie leichte Erosion, Sandl\u00f6cher, Sandl\u00f6cher oder Verunreinigungen. Wenn ja, schwei\u00dfen, reparieren oder reinigen Sie sie entsprechend.<\/p>\n\n\n\n
2.Problem: Leckage an der Motorhaube<\/h4>\n\n\n\n
Dieses Fehlerph\u00e4nomen tritt h\u00e4ufig bei Undichtigkeiten der Stopfbuchsdichtung auf.<\/p>\n\n\n\n
2-1.Korrekturma\u00dfnahme:<\/h4>\n\n\n\n
\u00dcberpr\u00fcfen Sie zun\u00e4chst, ob die Dichtung richtig sitzt und mit der Dichtungsnut kompatibel ist. Wenn ein Problem vorliegt, muss die Dichtung ausgetauscht oder die Dichtungsnut repariert werden. \u00dcberpr\u00fcfen Sie zweitens, ob die Dichtung Grate, Br\u00fcche oder Verdrehungen aufweist. Wenn dies der Fall ist, muss die Dichtung ausgetauscht werden. \u00dcberpr\u00fcfen Sie dann die Oberfl\u00e4che der Dichtungsnut auf Rauheiten oder andere M\u00e4ngel. Wenn M\u00e4ngel vorhanden sind, entfernen Sie diese oder erneuern Sie die besch\u00e4digten Teile.<\/p>\n\n\n\n
Wenn f\u00fcr die Haube oder Halterung eine Kompressionsdichtungspackung verwendet wird, muss der Einbau der Packung \u00fcberpr\u00fcft werden. Wenn sich herausstellt, dass die Packung verkehrt herum eingebaut wurde, muss sie entfernt und erneut mit der richtigen Methode eingebaut werden.<\/p>\n\n\n\n
3.Problem: Leckage im Ventilk\u00f6rperhohlraum<\/h4>\n\n\n\n
W\u00e4hrend des Gie\u00dfvorgangs k\u00f6nnen manchmal Gussfehler im Ventilk\u00f6rper auftreten, wie z. B. K\u00f6rnungs- und Sandl\u00f6cher. Sie sind w\u00e4hrend der Bearbeitung ohne zerst\u00f6rungsfreie Pr\u00fcfung schwer zu erkennen, aber sobald Druck auf den Ventilk\u00f6rper ausge\u00fcbt wird, werden versteckte Gussfehler sichtbar.<\/p>\n\n\n\n
3-1.Korrekturma\u00dfnahme:<\/h4>\n\n\n\n
Sollte dies der Fall sein, kann entsprechend der Norm geschwei\u00dft, repariert oder erneuert werden.<\/p>\n\n\n\n
4.Problem: Leckage am Ventilsitz und Ventilkeil<\/h4>\n\n\n\n
4.1 Leckagen treten am Ventilsitz und am Ventilkeil auf. Dies ist das h\u00e4ufigste Ph\u00e4nomen bei der Installation oder Wartung von Schieberventilen. Im Allgemeinen gibt es zwei Arten: Eine ist eine Leckage an der Dichtfl\u00e4che; die andere ist eine Leckage an der Dichtwurzel.<\/p>\n\n\n\n
4.1-1.Korrekturma\u00dfnahme: Als Erstes muss die Genauigkeit der Dichtkontaktfl\u00e4che des Ventilsitzes und des Ventilkeils \u00fcberpr\u00fcft werden. Die Dichtfl\u00e4che muss geschliffen werden. Wenn eine raue Oberfl\u00e4che vorhanden ist, muss diese entfernt und neu geschliffen werden. \u00dcberpr\u00fcfen Sie anschlie\u00dfend die Dichtfl\u00e4che auf Defekte wie Pockennarben, Einkerbungen, Sandl\u00f6cher, Risse usw. Wenn dies der Fall ist, sollten Sitz und Keil ausgetauscht werden. \u00dcberpr\u00fcfen Sie bei Ventilsitzen mit Druckfedern, ob die Federkraft der Druckfeder den Anforderungen entspricht. Wenn die Federkraft niedrig ist, sollte die Druckfeder erneuert werden. \u00dcberpr\u00fcfen Sie au\u00dferdem, dass die T-f\u00f6rmige Kupplung zwischen Ventilkeil und Schaft nicht zu locker ist und dass keine Neigung vorhanden ist. Wenn dies der Fall ist, sollte der Keil entfernt und auf die optimale Gr\u00f6\u00dfe eingestellt werden.<\/p>\n\n\n\n
4.2 Beim Einbau des Ventils k\u00f6nnen leicht Fremdk\u00f6rper wie Schwei\u00dfspuren, Eisenschrott und Verunreinigungen eindringen.<\/p>\n\n\n\n
4.2-1.Korrekturma\u00dfnahme: Entfernen Sie vor der Installation die R\u00fcckst\u00e4nde. Wenn Sie die Reinigung vergessen oder unvollst\u00e4ndig reinigen, erreicht der Ventilkeil nicht die gew\u00fcnschte Schlie\u00dftiefe und es kommt zu Undichtigkeiten. In diesem Fall sollte der Ventilk\u00f6rper entfernt und gereinigt werden.<\/p>\n\n\n\n
Der Ventilsitz muss mit einem Spezialwerkzeug installiert werden. \u00dcberpr\u00fcfen Sie, ob der Ventilsitz richtig installiert ist. Wenn die Gewinde weniger tief als erwartet sind, wird der Sitz undicht. In diesem Fall muss der Sitz mit einem Spezialwerkzeug installiert werden.<\/p>\n\n\n\n
Wie repariert man ein Absperrventil, das sich nicht \u00f6ffnet oder schlie\u00dft?<\/h3>\n\n\n\n
Die erste M\u00f6glichkeit besteht darin, dass das Drehmoment des Ventils zu gro\u00df ist und mehr Kraft zum Schlie\u00dfen oder \u00d6ffnen erfordert. Ersetzen Sie den Antrieb durch einen gr\u00f6\u00dferen<\/p>\n\n\n\n
Die zweite M\u00f6glichkeit besteht darin, dass sich beim Einbau des Ventils in die Rohrleitung Schwei\u00dfschlacke oder Schmutz am Boden des Ventils ansammelt, wodurch das Schlie\u00dfen des Schiebers blockiert wird. Dieser Schmutz muss entfernt werden. Die dritte M\u00f6glichkeit besteht darin, dass Schieber und Ventilsitz besch\u00e4digt wurden und rechtzeitig repariert und ersetzt werden m\u00fcssen.<\/p>\n\n\n\n
Siehe insbesondere Abschnitt 4.<\/p>\n\n\n\n
So ersetzen Sie ein Absperrventil, Ersetzen Sie das Absperrventil durch ein Kugelventil<\/h3>\n\n\n\n
Schlie\u00dfen Sie das Absperrventil vorn, sodass das Medium in einen statischen Zustand \u00fcbergeht, und lassen Sie das Medium in diesem Abschnitt der Rohrleitung ab. Wenn es sich um ein Flanschventil handelt, m\u00fcssen Sie die Schraube und Mutter der Verbindung entfernen, die Dichtfl\u00e4che reinigen, die Dichtung ersetzen und das neue Kugelventil wieder anschlie\u00dfen. Wenn es sich um ein Gewindeventil handelt, schrauben Sie es einfach fest. Bei SW- oder BW-Verbindungen schneiden Sie das neue Kugelventil ab und schwei\u00dfen es an Ort und Stelle.<\/p>\n\n\n\n
Wasserschieber<\/mark><\/strong><\/a> Probleme<\/h2>\n\n\n\nMein Absperrventil klemmt und ist offen. Was soll ich tun?<\/h3>\n\n\n\n
Wenn dein Absperrschieber<\/strong> offen ist und Sie es nicht schlie\u00dfen k\u00f6nnen, dann ist die einzige M\u00f6glichkeit, es abzulassen. In einigen F\u00e4llen k\u00f6nnen Klempner Ventile schnell austauschen, aber das stellt kein Risiko dar. In den meisten F\u00e4llen, wenn Ihr Absperrventil ein Problem hat und Ihr Absperrventil offen ist, ist es am besten, das Wasser abzulassen.<\/p>\n\n\n\nDas Problem, dass das Absperrventil nicht ge\u00f6ffnet werden kann<\/h3>\n\n\n\n
Wenn Sie ein Absperrventil haben, das sich nicht \u00f6ffnen l\u00e4sst, liegt das normalerweise an einer gebrochenen Spindel. Der Grund daf\u00fcr liegt normalerweise darin, dass der Klempner oder Meister das Gewinde festzieht, wenn das Ventil aufgrund von Schmutz, Kalk oder anderen Gr\u00fcnden geschlossen ist, wodurch das Gewinde bricht. Wenn sich das Ventil nicht leicht schlie\u00dfen l\u00e4sst, ist es am besten, das Absperrventil beim Ablassen des Wassers auszutauschen, um weitere Probleme mit dem Absperrventil und damit verbundene Mehrkosten zu vermeiden.<\/p>\n\n\n\n
So ersetzen Sie das Absperrventil, ohne dass Warmwasser verloren geht<\/h3>\n\n\n\n
Der beste Weg, das Ventil auszutauschen, besteht darin, zuerst das Rohr einzufrieren und dann das Ventil auszutauschen. Die einzige andere M\u00f6glichkeit besteht darin, das Absperrventil zu schlie\u00dfen und das untere Rohr abzutrennen. Sobald Sie die obere Mutter des Versorgungsrohrs gel\u00f6st haben, k\u00f6nnen Sie das Ventil sehr schnell austauschen. Dies muss von einem qualifizierten Notklempner durchgef\u00fchrt werden.<\/p>\n\n\n\n
Mein Absperrschieber schlie\u00dft nicht richtig, warum?<\/h3>\n\n\n\n
Der Grund, warum das Ventil nicht normal geschlossen werden kann, liegt darin, dass sich mit zunehmendem Alter des Schieberventils Schmutz oder Kalkablagerungen bilden, wodurch der Schlie\u00dfmechanismus nicht mehr normal schlie\u00dft. Dieses Problem l\u00e4sst sich am besten l\u00f6sen, indem Sie das Ventil entweder gr\u00fcndlich reinigen oder das Schieberventil austauschen.<\/p>\n\n\n\n
Beim Austausch des Absperrschiebers, ob dieser zuerst entleert werden muss<\/h3>\n\n\n\n
Wie im vorherigen Absatz erl\u00e4utert, m\u00fcssen Sie zum Ersetzen eines Ventils dieses nicht immer entleeren, sofern Sie \u00fcber die entsprechende Erfahrung und das entsprechende Werkzeug verf\u00fcgen.<\/p>\n\n\n\n
Was f\u00fchrt zum Platzen des Absperrschiebers?<\/h3>\n\n\n\n
Der Grund f\u00fcr den Bruch des Absperrschiebers liegt darin, dass das Ventil zerbrechlich ist und der Druck zu hoch ist, wenn das Absperrschieber geschlossen ist. Das Spindelgewinde ist nicht tief genug, um in das Ventil einzudringen. Wenn der Druck also zu gro\u00df ist, gibt es nicht viel Spielraum, um einen Widerstand zu stoppen. Es ist ein bisschen so, als w\u00fcrde man einen Zweig brechen, anstatt einen Stock zu brechen.<\/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.

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

Das Problem, dass das Absperrventil nicht ge\u00f6ffnet werden kann<\/h3>\n\n\n\n
Wenn Sie ein Absperrventil haben, das sich nicht \u00f6ffnen l\u00e4sst, liegt das normalerweise an einer gebrochenen Spindel. Der Grund daf\u00fcr liegt normalerweise darin, dass der Klempner oder Meister das Gewinde festzieht, wenn das Ventil aufgrund von Schmutz, Kalk oder anderen Gr\u00fcnden geschlossen ist, wodurch das Gewinde bricht. Wenn sich das Ventil nicht leicht schlie\u00dfen l\u00e4sst, ist es am besten, das Absperrventil beim Ablassen des Wassers auszutauschen, um weitere Probleme mit dem Absperrventil und damit verbundene Mehrkosten zu vermeiden.<\/p>\n\n\n\n
So ersetzen Sie das Absperrventil, ohne dass Warmwasser verloren geht<\/h3>\n\n\n\n
Der beste Weg, das Ventil auszutauschen, besteht darin, zuerst das Rohr einzufrieren und dann das Ventil auszutauschen. Die einzige andere M\u00f6glichkeit besteht darin, das Absperrventil zu schlie\u00dfen und das untere Rohr abzutrennen. Sobald Sie die obere Mutter des Versorgungsrohrs gel\u00f6st haben, k\u00f6nnen Sie das Ventil sehr schnell austauschen. Dies muss von einem qualifizierten Notklempner durchgef\u00fchrt werden.<\/p>\n\n\n\n
Mein Absperrschieber schlie\u00dft nicht richtig, warum?<\/h3>\n\n\n\n
Der Grund, warum das Ventil nicht normal geschlossen werden kann, liegt darin, dass sich mit zunehmendem Alter des Schieberventils Schmutz oder Kalkablagerungen bilden, wodurch der Schlie\u00dfmechanismus nicht mehr normal schlie\u00dft. Dieses Problem l\u00e4sst sich am besten l\u00f6sen, indem Sie das Ventil entweder gr\u00fcndlich reinigen oder das Schieberventil austauschen.<\/p>\n\n\n\n
Beim Austausch des Absperrschiebers, ob dieser zuerst entleert werden muss<\/h3>\n\n\n\n
Wie im vorherigen Absatz erl\u00e4utert, m\u00fcssen Sie zum Ersetzen eines Ventils dieses nicht immer entleeren, sofern Sie \u00fcber die entsprechende Erfahrung und das entsprechende Werkzeug verf\u00fcgen.<\/p>\n\n\n\n
Was f\u00fchrt zum Platzen des Absperrschiebers?<\/h3>\n\n\n\n
Der Grund f\u00fcr den Bruch des Absperrschiebers liegt darin, dass das Ventil zerbrechlich ist und der Druck zu hoch ist, wenn das Absperrschieber geschlossen ist. Das Spindelgewinde ist nicht tief genug, um in das Ventil einzudringen. Wenn der Druck also zu gro\u00df ist, gibt es nicht viel Spielraum, um einen Widerstand zu stoppen. Es ist ein bisschen so, als w\u00fcrde man einen Zweig brechen, anstatt einen Stock zu brechen.<\/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
