Gas valve leakage causes and treatment methods which have? (1) gas valve causes the valve body, the lower cover screws are not tightened; body of the rubber membrane damage; air inlet seal aging damage. (2) Gas pressure reducing valve treatment Tighten the upper and lower cover screws; replace the rubber membrane; the rubber seal ring connecting the pressure reducing valve and the cylinder serves as a sealed air supply, which will wear, deteriorate after aging or even In the replacement of the cylinder will fall off and cause a lot of running gas, causing serious accidents. Therefore, the requirements of each replacement cylinder, valve installation, special attention should be paid to check the rubber seal is intact, with or without aging, wear phenomenon, especially when installed, you must check the seal is missing. If it is worn or worn out, it should be replaced promptly, but it must not be replaced by film cutter. Special sealing ring must be used. (3) gas diaphragm valve aging rubber film is a common cause of leakage. It is understood that many users in order to run out of gas cylinders will be reversed, with hot water or fire heating cylinders, etc., so that the gas bottle bottom residue into the valve cavity, a long time after the diaphragm caused by aging leakage. For security, these practices are not allowed. In addition, if the gas regulator valve loose loosening, or tighten the mother wire to tighten the upper and lower bonnet rubber membrane edge crushing, can also cause leakage. In particular, the pressure relief valve rubber film locking device off or rupture of the rubber film, can cause high pressure air supply and explosion. (4) The structure of the gas pressure reducing valve is tight. The products are carefully debugged before leaving the factory and are strictly tested before they leave the factory. Therefore, the connecting screws and adjusting parts are not allowed to be disassembled or disturbed randomly, Pressure valve sealing performance and buck, regulator performance, but also to prevent damage caused by the demolition of high-pressure direct gas and cause a fire accident.
