The causes of gas filter leakage are: the upper and lower cover screws of the valve body are not tightened; the rubber film inside the valve body is damaged; the sealing ring of the air inlet is aged and damaged. Disposal skills: tighten the upper and lower cover screws; change the rubber film; the rubber seal ring at the pressure reducing valve and the continuous part of the cylinder is used for sealing gas supply. It will wear and age after permanent application, and even fall off when changing the cylinder, causing a large number of gas escape, causing tension and disorder. Therefore, every time the cylinder is changed and the pressure relief valve is installed, it is required to pay attention to the inspection of whether the rubber sealing ring is intact, whether there are signs of aging and wear, especially in the installation, it is necessary to inspect whether the sealing ring is lost. If it has been aged or worn, it should be changed in real time, but it can not be replaced by cutting the film, and the sealing ring must be used.
The pressure cannot be adjusted due to respiratory hole infarction. In case of original trouble, do not pay attention to normal maintenance and cleaning, let sundries contaminate the pressure reducing valve, so that the small round hole with a diameter of about 1mm in its upper shell is blocked. The small round hole is the breathing hole. The breathing hole is the same as the upper cavity of the rubber film in the pressure reducing valve. When the film moves high and low, the atmosphere continues to flow from the breathing hole to complete the pressure regulation. Therefore, if the breathing hole is blocked, the atmosphere above the diaphragm will not be able to break even normally, which will cause the pressure regulation of liquefied kerosene gas to fail, cause the high-pressure liquefied kerosene gas to simply supply air, make the flame of the gas appliance suddenly increase or take off the fire to put out the fire and run off the gas, resulting in the fire and disorder.
Gas filter leakage disposal skills: often search and clean, connect the flow of breathing holes. In case of leakage of liquefied kerosene gas from the breathing hole, the rubber film shall be damaged. The angle valve shall be closed, the pressure reducing valve shall be removed, the membrane shall be replaced or a new pressure reducing valve shall be replaced.
The flow rate or pressure is not normal, and the flow rate is reduced. The main reason is that the application is too long, which causes the rubber seal ring to stretch and deform. If it is deformed, replace the rubber ring. Inlet pressure is lower than: usually, it is caused by clogging of filter screen.
