Introduction of Y13H Female Pilot Piston Steam Pressure Reducing Valve


内螺纹先导活塞式蒸汽减压阀 属于先导活塞式减压阀。 This series of internally threaded pilot piston 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, cylinder liner, 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 diaphragm is used to sense the outlet pressure change, and the pilot valve is used to open and close the driving piston to adjust the size of the over-flow area of the main valve throttling part to achieve the function of pressure reduction and pressure stabilization.
薄膜型减压阀 主要用于蒸汽管路,起减压稳压作用。 This membrane type pressure reducing valve is mainly used for steam pipelines, and plays the role of pressure reduction and pressure stabilization.
