The main reasons for the air leakage of the LPG vaporizer 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 put the gas cylinder upside down, heat the gas cylinder with hot water or fire, etc., so that the residue at the bottom of the gas bottle will enter the inner cavity of the pressure reducing valve, and the aging of the diaphragm will cause leakage after a long time. leak.
For your own safety, these practices are not allowed. In addition, if the fixed female wire of the LPG vaporizer is loose, or the edge of the rubber film is crushed when the female 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.
Solution to air leakage: 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, and even when replacing the steel cylinder It will fall off by itself and cause a lot of air loss, causing serious accidents.
Therefore, it is required that every time the steel cylinder is replaced and the pressure reducing valve is installed, attention should be paid to check whether the rubber sealing ring is intact, whether there is aging or wear, and mainly to check whether the sealing ring is missing during installation. 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.
