The main reasons for the leakage of LPG carburetor are that the upper and lower cover screws of the valve body are not tightened; the rubber film in the valve body is damaged; the sealing ring of the air inlet is aged and damaged.
The aging of the rubber film of the LPG vaporizer is a common cause of air leakage. In order to use up the gas at the bottom of the bottle, many users turn the gas bottle upside down, heat the gas bottle with hot water or fire, etc., which will cause the residue at the bottom of the gas bottle to enter the cavity of the pressure reducing valve. After a long time, the diaphragm will age and cause seepage. leak.
For their own safety, these practices are not allowed. In addition, if the fixed mother wire of the LPG vaporizer is loose, or the edge of the rubber film is crushed when the mother wire is tightened to fasten the upper and lower valve covers, it will also cause air leakage. The main reason is that the rubber film locking device of the pressure reducing valve falls off or the rubber film ruptures, which can cause high-pressure air supply and cause accidents.
Air leakage solution: tighten the upper and lower cover screws; replace the rubber film; the rubber sealing ring at the connection between the pressure reducing valve and the steel cylinder plays the role of sealing the air supply. It will wear and age after long-term use, even when replacing the steel cylinder. It will fall off on its own and cause a lot of outgassing, causing serious accidents.
Therefore, it is required that each time the cylinder is replaced and the pressure reducing valve is installed, attention should be paid to check whether the rubber sealing ring is in good condition, whether there is aging or wear, mainly when installing, check whether the sealing ring is missing. If it is aged or worn, it should be replaced in time, but it must not be replaced by film, and the corresponding sealing ring should be used.
