Gas valve maintenance methods have? Gas valve maintenance methods are the following: (1) gas valve cover the breathing hole is used to adjust the air volume to ensure that the decompression valve from the buck and regulator, can not be blocked. In the past, many users do not understand the role of breathing holes, resulting in gas valve has been dirty and unwilling to clean, and some people do not pay attention when using cloth to clean the valve, often on the bonnet clean Clean, and breathing holes are in the process of using cloth wipe blocked by debris caused by accident. Therefore, during cleaning, if the breathing holes are found to be clogged, use a thin wire to be careful, but not to puncture or damage the rubber film inside the pressure reducing valve. (2) liquefied petroleum gas cylinder and location If you do not meet the requirements, it is possible to liquefied petroleum gas into the gas valve, causing the rubber seal dissolved dissolved expansion of the air intake gap smaller or blocked, affecting normal use. In addition, rubber seals are wearing parts, long-term use, due to the corrosive effect of liquefied petroleum gas so that it appears pit phenomenon, resulting in leaks. Therefore, the gas valve should be regularly inspected. (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 by the user to avoid decreasing or reducing 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.
