产品介绍

一、进口活塞式蒸汽减压阀概述    

进口活塞式蒸汽减压阀，Piston type steam reducing valve，由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、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，实现减压稳压功能进口活塞式蒸汽减压阀主要用于蒸汽管路。

A piston type steam reducing valve consists of a main valve and a pilot valve. The main valve is composed of parts such as valve seat, main valve disc, piston, spring, etc. The pilot valve is mainly composed of parts such as valve seat, valve disc, diaphragm, spring, and regulating spring. By adjusting the spring pressure to set the outlet pressure, using the diaphragm to sense the change in outlet pressure, and driving the piston to adjust the size of the flow area at the throttle position of the main valve through the opening and closing of the pilot valve, the pressure reducing and stabilizing function is achieved. The imported piston type steam pressure reducing valve is mainly used in steam pipelines.
