This valve is mainly used for regulating the flow/pressure in the water supply and drainage pipeline (especially in the long line of water conveying pipeline). Can also be used for reservoirs, hydropower stations as a vent valve (safety valve) use. The main valve body is the inner and outer circular double-layer cylinder structure, the regulating structure is the crank piston mechanism, the slider piston can be guided by the guide rail in the inner cylinder, and the axial displacement can be done along the pipeline to change the flow channel through the area, so as to realize the control and regulation. The flow channel is axially symmetrical flow fluid in the flow linear valve body is not easy to produce turbulence, the head loss is small, any position in the valve cavity flow cross-section are annular, to ensure linear operation characteristics. The regulator controls the electric device to change the valve opening
Product introduction of flow regulating valve
This valve is mainly used for regulating the flow/pressure in the water supply and drainage pipeline (especially in the long line of water conveying pipeline). Can also be used for reservoirs, hydropower stations as a vent valve (safety valve) use.
The main valve body is the inner and outer circular double-layer cylinder structure, the regulating structure is the crank piston mechanism, the slider piston can be guided by the guide rail in the inner cylinder, and the axial displacement can be done along the pipeline to change the flow channel through the area, so as to realize the control and regulation. The flow channel is axially symmetrical flow fluid in the flow linear valve body is not easy to produce turbulence, the head loss is small, any position in the valve cavity flow cross-section are annular, to ensure linear operation characteristics. The regulator controls the electric device to change the valve opening to achieve automatic pressure reduction and throttling functions.
the main features:
1. Automatic adjustment, high control precision, the flow/pressure after the valve is less affected by the flow/pressure before the valve;
2. Axial symmetrical flow channel design, no turbulence, small head loss;
3, piston, squirrel cage are running on the guide rail, resistance is small, high precision adjustment;
4, Suspension and large grid spacing design, debris will not be blocked;
5. High-speed water flows from the grid and collides with each other in the axial area of the valve body flow channel to eliminate energy, so that cavitation occurs in the center of the valve and does not damage the valve parts;
6, hard and soft seal, seal pair without relative friction, good sealing, long service life.
