Details
Based on the advanced experience of Europe and Japan and the experience of design, manufacture and practice in China, the piston regulating valve is a kind of rectified and pressure-regulating valve developed according to the characteristics of fluid mechanics. Consists of the valve, piston, connecting rod, valve stem, bushings, valve seat, sealing ring and other main parts, because of its closed hollow sliding piston cylinder or cone, but in the body of cylinder guided by fork brought along the pipeline center for axial movement, so as to change the port area, so as to realize the switch, adjust the flow or pressure relief valve function, so the piston basins is valve, also known as the piston multi-function control valve, piston basins pressure regulating valve and so on, this is a new type of pressure balance type based on the axial flow type control valve, the valve with valve cone and guide energy dissipation fin plate segmentation for energy dissipation and rectification, export to streamline axisymmetric flow, The fluid in the body can be well guided without turbulence and can significantly reduce the noise and vibration of the valve. Ensure that the valve also has good cavitation resistance at high pressure. It can solve flocculation, eliminate gas erosion, avoid vibration and eliminate water hammer, so it is widely used in power station, water diversion and water supply.
