Anhui pressure reducing valve high sensitivity steam pressure reducing valve selection quotation technical support service

High sensitivity steam pressure reducing valve is a pilot piston pressure reducing valve. It consists of two parts, the main valve and the 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 part is adjusted by the pilot valve opening and closing to drive the piston to realize the function of pressure reduction and pressure stabilization. The high-sensitivity steam pressure reducing valve has made the following improvements on the basis of the ordinary pressure reducing valve, increasing the area of the piston, changing the throttle structure, changing the sealing form, improving the structure of the pilot valve and adjusting the spring, so as to Improved product performance. 1. Improved the sensing efficiency and sensitivity of outlet pressure changes, greatly reducing the pressure deviation caused by upstream pressure changes, flow changes and other factors. 2. Improved streamline distribution and reduced noise. 3. Improved seal surface structure and prolonged seal surface life. High-sensitivity steam pressure reducing valve is mainly used in steam pipelines, suitable for steam pipelines with large inlet pressure changes and large flow changes.
