进口先导活塞式气体减压阀产品简介： 德国洛克《DE LOCKE》进口先导活塞式气体减压阀属于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节弹簧压力设定出口压力，利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。
Import pilot piston type gas pressure reducing valve belongs to the pilot piston type pressure reducing valve. By the main valve and pilot valve composed of two parts. The main valve mainly by the valve seat, the main valve plate, piston, cylinder liner, springs and other parts. Pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, adjusting spring and other parts. By adjusting the spring pressure to set the outlet pressure, the diaphragm pressure sensor is used to adjust the flow area of the throttle part of the main valve through the pilot valve opening and closing to drive the piston.
