型先导活塞式气体减压阀介绍 Introduction of YK43Y pilot piston gas pressure reducing valve  

    先导活塞式气体减压阀 属于先导活塞式减压阀。 This series of pilot piston 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. 先导式超大膜片高灵敏度减压阀 主要用于气体管路,如空气、氮气、氧气、氢气、液化气、天然气等气体。 The pilot-type super large diaphragm high sensitivity pressure reducing valve is mainly used for gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
