Direct Acting Bellows Pressure Reducing Valve Suitable For Piping Of Gas And Liquid Medium
Description
This series reducing valve is direct acting bellows pressure reducing valve, It is mainly composed of bellows, adjusting spring, valve seat and valve flap. It sense the change of lower stream pressure through the bellows and drive the valve flap, change and control the valve opening to realize the function of pressure reducing the regulating. Set the outlet pressure by adjusting the spring pressure through adjusting bolt The product works stably and flexibly. It is suitable for piping of gas and liquid medium.
Bellows pressure reducing valve working principle and structure
1. Bellows pressure reducing valve is a control valve which work by control the inner open-close part opening to control the flow of the medium and reduce the medium pressure. At the same time with upstream pressure of the valve to adjust the opening, keep the valve downstream pressure within a certain range. Although the inlet pressure keep changing, the outlet pressure keep within the set range. So it can protect the downstream living and producing products.
2. Bellows pressure reducing valve is consist of valve body, valve cover, valve disc, valve seal, valve stem, Bellows and adjusting spring. At the cavity inlet port has disc and body sealing ring and auxiliary spring. Auxiliary spring's function is to keep the disc and body sealing ring automatic sealing. The outlet cavity assemble spring sealing element (bellows) which guaranteed the valve downstream liquid leakage and overcome non-uniform pressure. Screw is to adjust the spring load pressure which keep the reducing valve well working performance.
