Dies sind unkomplizierte und in der Regel gut verarbeitete Maschinen, die selten kaputtgehen. Wenn Sie auf einen defekten Absperrschieber sto\u00dfen, ist es sehr wahrscheinlich, dass der Ausbau und Austausch weitaus billiger ist, als sich wegen der internen Teile an den Originalhersteller zu wenden. Es gibt eine Reihe von Ma\u00dfnahmen, mit denen sich ein festsitzender Absperrschieber wahrscheinlich wieder l\u00f6sen l\u00e4sst.\r\n\r\n\r\n\r\n\r\n\r\nERHALTEN SIE INFORMATIONEN ZUR REPARATUR VON SCHIEBERVENTILEN<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n

Hinweise zum \u00d6ffnen eines defekten Absperrschiebers<\/h2>\r\n\r\n\r\n\r\n\r\nDas Ventil \u00f6ffnet nicht und es gibt mehrere M\u00f6glichkeiten\r\n\r\n\r\n\r\n\r\n\r\n1. Die Rohre wurden l\u00e4ngere Zeit nicht benutzt, wodurch sich im Inneren der Ventile Rost gebildet hat und diese sich nicht mehr \u00f6ffnen lassen.\r\n\r\n\r\n\r\n\r\n\r\nSchlie\u00dfen Sie das Absperrventil vor dem Ventil, entfernen Sie das Ventil, pr\u00fcfen Sie, ob Schieber, Schaft und Schaftmutter verrostet und besch\u00e4digt sind, und ersetzen Sie sie durch neue Teile. Wenn sie nicht besch\u00e4digt oder verklemmt sind, entfernen Sie den Rost und tragen Sie Rostschutz\u00f6l auf.\r\n\r\n\r\n\r\n\r\n\r\n2. Die Rohrleitung wurde normal verwendet und das Absperrventil unterliegt beim \u00d6ffnen einem unsicheren Widerstand.\r\n\r\n\r\n\r\n\r\n\r\nEs gibt zwei oben genannte Situationen: Ein Schieberventil steckt aufgrund eines Fremdk\u00f6rpers in der Rohrleitung fest. Schlie\u00dfen Sie das Ventil, bevor Sie es abschalten. Entfernen Sie das Ventil, reinigen Sie den Fremdk\u00f6rper und Sie k\u00f6nnen es normal weiter verwenden. Zweitens: Da die k\u00fcnstliche Schaltkraft zu gro\u00df ist und sich der Ventilschaft aufgrund des \u00fcberm\u00e4\u00dfigen Drehmoments verbiegt, muss das Ventil entfernt und durch einen neuen Schaft ersetzt werden.\r\n\r\n\r\n\r\n\r\n\r\nDas \u00d6ffnen eines defekten Schiebers ist nur eine vor\u00fcbergehende Empfehlung. Bei l\u00e4ngerem Gebrauch empfiehlt sich der Austausch oder die Reparatur des Schiebers. Bei weniger teuren Schiebern empfiehlt sich jedoch der Austausch.\r\n\r\n\r\n\r\n\r\n\r\nDie folgenden Artikel geben Ratschl\u00e4ge zur Reparatur von Schiebern\r\n\r\n\r\n\r\n\r\n

Wie \u00f6ffnet man ein defektes Absperrventil?<\/h2>\r\n\r\n\r\n\r\n

Vor Arbeiten am Ventil<\/h3>\r\n\r\n\r\n\r\n\r\n\u00dcberpr\u00fcfen Sie zun\u00e4chst, ob sich Wasser in der Leitung befindet: Wenn die Versorgungs- oder Brunnenpumpe ein Problem hat oder die Leitung eingefroren ist, liegt die Ursache nicht beim Absperrventil. Wenn die Versorgung ansonsten einwandfrei ist, isolieren Sie das Absperrventil, wenn m\u00f6glich. Das Schlie\u00dfen anderer Ventile oder Absperrh\u00e4hne vor und nach dem Absperrventil kann sp\u00e4ter Schmutz und \u00c4rger vermeiden. Stellen Sie nach M\u00f6glichkeit eine Sch\u00fcssel oder einen Eimer unter das Ventil; andernfalls stopfen Sie Handt\u00fccher um den Bereich herum aus.\r\n\r\n\r\n\r\n\r\n

Kriech\u00f6l<\/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

Zus\u00e4tzliche Hebelwirkung<\/h3>\r\n\r\n\r\n\r\n\r\nWenn das Absperrventil nach mindestens dreimaliger Anwendung des Kriech\u00f6ls immer noch feststeckt, versuchen Sie, die Hebelwirkung am Griff zu erh\u00f6hen. F\u00fchren Sie eine stabile Schraubendreherklinge durch die Zinken des Griffs oder verwenden Sie eine Schraubstockzange am Schaft. St\u00fctzen Sie das Ventil mit Ihrer freien Hand, um zu verhindern, dass die mit dem Hebel ausge\u00fcbte Kraft auf das Rohr \u00fcbertragen wird, und erh\u00f6hen Sie den Druck sehr langsam, bis die Klemme bricht oder Sie bef\u00fcrchten, dass sich die Rohre auf beiden Seiten des Ventils verbiegen, wenn Sie weiter schrauben.\r\n\r\n\r\n\r\n\r\n

Hitze<\/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

So zerlegen Sie ein festsitzendes Absperrventil<\/h2>\r\n\r\n\r\n\r\n\r\nAbsperrventile werden normalerweise an eine Wand oder zwischen zwei Rohrst\u00fccke geschraubt. Bevor Sie sie entfernen, k\u00f6nnen Sie versuchen, das Ventil nur mit dem Wasser im System zu entstopfen. Drehen Sie die Wasserzufuhr so hoch wie m\u00f6glich auf und \u00f6ffnen und schlie\u00dfen Sie das Ventil dann langsam so weit wie m\u00f6glich. Dadurch k\u00f6nnen sich einige Ablagerungen l\u00f6sen und Sie k\u00f6nnen das Absperrventil vollst\u00e4ndig schlie\u00dfen.\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\nWenn Sie die Haube abgeschraubt haben, k\u00f6nnen Sie die Oberseite des Schieberventils mit Griff und Sitz vom K\u00f6rper abnehmen. So k\u00f6nnen Sie Ihr Ventil von oben mit einer Zahnb\u00fcrste oder einem anderen Reinigungswerkzeug reinigen.\r\n\r\n\r\n\r\n\r\n

So reparieren Sie ein festsitzendes Absperrventil<\/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\nEin defektes Schieberventil ist nicht schwer zu reparieren, aber es ist noch einfacher, es zu verhindern. Diese Probleme werden in der Regel durch Mineralablagerungen verursacht. Sie sollten Ihre Schieberventile daher alle paar Monate vollst\u00e4ndig schlie\u00dfen und \u00f6ffnen, um m\u00f6gliche Probleme zu beheben. Wenn Ihr Schieberventil starke Lochfra\u00df- oder Korrosionssch\u00e4den aufweist, m\u00fcssen Sie es ersetzen.

If you encounter a broken gate valve, it is very likely that removal and replacement will be far cheaper than contacting the original manufacturer for internal parts. There are a number of measures that will probably free up a seized gate valve. GET REPAIR GATE VALVE INFORMATION Advice on Open a Broken Gate Valve The valve does not open and there are several possibilities 1\u3001The pipes have not been used for a long time, causing rust inside the valves and preventing them from opening. Close the shut-off valve in front of the valve, remove the valve, check if the gate, stem, and stem nut are rusted and damaged, and replace them with new parts. If not damaged or jammed, clean up the rust and brush on anti-rust oil. 2\u3001The pipeline has been used normally and the gate valve is subject to uncertain resistance during the opening. There are two situations above, one gate valve is stuck by a foreign object in the pipeline, close the valve before shutting off the valve, remove the valve, clean the foreign object, you can continue to use normally. Second, because the artificial switching force is too large, causing the valve stem to bend due to excessive torque, the same need to remove from the valve and replace with the new stem\u3002 Opening a broken gate valve is only a temporary recommendation, if it is used for a long time it is recommended that it is replaced gate valve or repair gate valve, but for less expensive gate valves it is recommended that it is replaced. The following articles are advice on gate valve repair How to Open a Broken Gate Valve? Before Working on the Valve First check that there is water in the pipe: If the utility or well pump is experiencing an issue or the pipe is frozen, the gate valve is not to blame. If the supply is otherwise fine, isolate the gate valve if possible. Closing other valves, or stop-taps, up and downstream could save mess and irritation later. Position a bowl or bucket beneath the valve if possible; otherwise, stuff towels around the area. Penetrating Oil Penetrating oil usually works to free gate valves that are seized for no other reason than lack of use. The lubricating oil found in almost every home, garage, and workshop in the U.S. is not — contrary to popular opinion — a penetrating oil. Its use will do little more than making the gate valve slippery and more difficult to work on. True penetrating oils can be found in auto parts stores and, occasionally, in the auto aisles of department stores. Clean away any verdigris or atmospheric deposits from the gate valve’s visible threads, follow the oil manufacturer’s directions for use and wait time, then tap the valve gently but firmly with a lightweight hammer to jar free any foreign matter gluing up the threads and try to open it as normal. Use a non-flammable penetrating oil in case the subsequent application of heat is necessary. Additional Leverage If the gate valve is still stuck after using the penetrating oil at least three times, try extending the leverage you have on the handle. Slip a sturdy screwdriver blade through the tines of the handle or use a pair of vise grips on the stem. Support the valve with your free hand so as to prevent the force you apply with the lever from being transferred to the pipe and very gradually increase the pressure until the seize breaks or you fear continuing will bend the pipes on either side of the valve. Heat Heat is often used to free up two metal components that have become bonded; nuts locked onto bolts by rust are almost certainly the most common use. The idea is to make one component of the valve heat up much faster than the other so that one expands while the other doesn’t, causing the unwanted bond to crack. Heating slowly, therefore, does not work. Only an extremely hot flame will work, such as a soldering blow-torch or a welding or cutting torch. Caution must be used to avoid scorching or setting fire to the gate valve’s surroundings. Use the heat source judiciously — do not leave the flame in contact with the valve for so long that any washers catch fire or liquefy and begin to leak — then apply leveraged pressure immediately. How to Disassemble a Stuck Gate Valve ate valves are typically screwed to a wall or between two pieces of piping. Before removing it, you can attempt to unclog the valve using just the water in the system. Turn the water source on as high as possible, then slowly open and close the valve as fully as it will let you. This could loosen some debris and allow you to close the gate valve fully. If this doesn’t do the trick, you should turn off the water source and remove the valve from the pipeline. This is typically done by unscrewing the ends. Once the valve is disconnected, use pliers to loosen the gate valve’s bonnet, as shown in the picture. Do not loosen the packing nut, as it is what holds the components together that keep fluid from leaking up the stem. When you have unscrewed the bonnet, you will be able to remove the top of the gate valve, with the handle and seating, from the body. This will allow you to clean your valve from the top, using a toothbrush or other cleaning tool. How to Rebuilt A Stuck Gate Valve Congratulations! Your gate valve is clean and clear! Now all that’s left is to put it together. This is a simple process if you have only disconnected the bonnet. Slide the gate back into the proper position in the valve’s body then screw the gate valve bonnet until secure. Test the valve by turning the handle. Ensure that the gate opens and closes fully. Once you are sure it is working properly, put it back into its place in the pipeline, using fresh pipe dope or sealant tape. A malfunctioning gate valve is not difficult to repair, but it is even easier to prevent. These problems are typically caused by mineral buildup, so you should fully close and open your gate valves every few months to clear potential problems. If your gate valve has severe pitting or corrosion, you will need to replace it.
