The air filtration pressure decompression valve is a auxiliary device for regulating pressure on a pneumatic film. The internal internal is mainly composed of the main valve and guide valve. The interaction of these two parts can be adjusted to adjust the spring pressure to achieve the function of gas decompression and regulation.The air filtration pressure reduction valve is mainly used in the gas pipeline, which is used to control the output and circulation of gas such as air, oxygen, hydrogen, liquefied gas, and natural gas.
Air filtration pressure reduction valve function
The air filtration pressure reduction valve is a smart valve that adjusts the controller and pipeline pressure through its own energy.The pressure in the gas pipeline often changes with changes in the pressure and flow of the in and out system.Therefore, the air filtration pressure decompression valve is set to keep the pressure in the gas pipeline always within a safe and stable range through the internal pressure setting, so as to achieve regulating the voltage of the gas and achieve stabilization and decompression effects.The air filtration pressure reduction valve can control the fixed export pressure of the main valve, so that the pressure of the main valve exit does not change due to changes in the pressure of the entrance and export, nor does it change the pressure of this exit due to changes in the volume of the gas in and out.The air filtration pressure reduction valve is a pilot pressure decompression valve. When the pressure generated by the pressure reduction valve is too high, the spring will be directly lowered through the spring. However, the spring is too large, and the range of output pressure fluctuations are too large.Therefore, the air filtration pressure reduction valve device has an auxiliary small straight pressure decompression valve to make up for the shortcomings of the air filtration pressure reduction valve.

The principle of air filtration pressure reduction valve
After the compressed air input of 0.3 ~ 1.0MPa, it will enter the filtering room. After entering, it will remove water, and dust treatment of the gas.At this time, the given spring will push the ball valve away, so after that, the air pressure will enter the output pipeline, and it will enter the feedback gas chamber through a small hole.At this time, the air pressure will emit some force on the membrane.However, there are certain interference in the outside world, and the output pressure will be disturbed by the outside world. In this way, the output voltage will be higher than the given value higher than the given value.If it is high, the membrane will move above. At this time, the valve stems and membrane cores will leave, then the air pressure will enter the atmosphere after the small hole, and finally reach a balance.Then if it is low, the membrane will move downwards, because the spring will lose balance, and the ball valve will be opened after the downward move, so that the gas will come in for the pressure of the air pressure.Therefore, the output voltage will always be on one fixed value required.
