Gas pressure reducing valve works

Gas valve working principle what? Gas valve working principle is as follows: [Pressure reducing valve working principle] Gas pressure reducing valve structure as shown in the working principle of the gas valve. We know that liquefied petroleum gas (LPG) is high pressure gas which comes out of the cylinder and then reaches the decompression chamber through the intake pipe. When the user turns off the switch with the gas appliance, as the liquefied petroleum gas entering the decompression chamber increases and its pressure rises, The spring is pressed against the top of the rubber membrane, and part of the air existing in the upper air chamber is exhausted from the valve body by the breathing hole. In this way, forcing the lever to move upward, using leverage to close the valve port, cut off the LPG inlet passage, the pressure relief valve outlet pressure will not rise. When the gas appliance with the switch is turned on, liquefied petroleum gas outflow from the relief valve so that the decompression chamber pressure drops, the rubber film concave, driven lever down, the outside air from the breathing hole into the upper chamber, the valve pad to the In the move, the intake nozzle becomes larger, the intake air volume increases, the pressure increases. This repeated adjustment process so that the decompression chamber pressure is always constant, regardless of intake pressure is high or low, the outlet pressure is always stable, and thus until the role of buck and regulator. ==================================== (This article is published by Asia Fluid Network Fluid Network)
