先导活塞式气体减压阀 简介 I. Brief introduction of YK43X / F pilot piston gas pressure reducing valve :
The gas pressure reducing valve is a pilot piston pressure reducing valve. It consists of a main valve and a pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting and adjusting the spring pressure, the outlet pressure changes are sensed by the diaphragm, and the size of the over-flow area of the main valve throttling position is adjusted by the pilot valve opening and closing of the driving piston to realize the function of pressure reduction and pressure stabilization. This product is mainly used for gas pipelines, such as air, nitrogen, argon, chlorine, oxygen, coal gas, hydrogen, ammonia, liquefied gas, natural gas, compressed air and other gases.
