Working principle of gas pressure reducing valve

Summary:Working principle of gas pressure reducing valve
        As we know, when the gas Liquefied petroleum gas comes out of the cylinder as a high-pressure gas, it first enters the decompression chamber through the intake pipe. When the user switches off the gas appliance, as more Liquefied petroleum gas enter the decompression chamber, the pressure increases, the rubber film pressed by the spring is pushed up, and part of the air existing in the upper air chamber is discharged from the valve body through a breathing hole. This forces the lever up and uses the lever to close the valve, cutting off access to the Liquefied petroleum gas inlet so that the pressure at the relief valve outlet does not rise.

        When the gas appliance is switched on, the Liquefied petroleum gas flows out of the pressure reducing valve, causing the pressure in the pressure reducing chamber to drop. The concave rubber film leads the lever to move down, and external air enters the upper air chamber through the breathing holes, the valve cushion moves to the middle, the intake nozzle becomes larger, the intake quantity increases, and the pressure increases. In this way, the pressure of the decompression chamber is always constant, that is, no matter the inlet pressure is high or low, the outlet pressure is always stable until the role of decompression and pressure stabilization.
