Structural characteristics and use of high-sensitivity pressure reducing valve
Structural characteristics and uses of high-sensitivity valve: High-sensitivity valve belongs to the pilot piston valve. The main valve and pilot valve composed of two parts. The main valve from the valve seat, the main valve disk, piston, spring and other components. Pilot valve mainly by the valve seat, disc, diaphragm, spring, adjusting spring and other components. By adjusting the spring pressure to set the outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston to adjust the size of the main valve throttle flow area, to achieve decompression regulator function. High-sensitivity valve in the ordinary valve on the basis of the following improvements have been made to increase the piston area, changing the throttle structure, changing the seal form, improved pilot valve structure and adjust the spring form, which from the following aspects to improve The product's performance. 1, improve the sensing performance of the outlet pressure changes, improve the sensitivity, greatly reducing the pressure deviation due to upstream pressure changes, flow changes and other factors. 2, improved streamline distribution, reducing noise. 3, improved sealing surface structure, extending the sealing surface life. 4, high-sensitivity pressure reducing valve is mainly used for steam pipelines, suitable for large changes in inlet pressure, large steam flow changes in the pipeline.
