The water turbine inlet ball valve is mainly used in large and medium-sized hydropower stations.
Installed in front of the turbine and used as the inlet valve for the turbine.
The upstream is connected to the pressure steel pipe, and the downstream is connected to the inlet pipe of the snail shell.
On the one hand, when the water turbine or generator needs maintenance;
By using this valve to cut off the water flow in the pipeline, safe maintenance can be carried out.
On the other hand, when there is an abnormal situation in the water turbine or generator,
It can quickly and effectively cut off water flow, preventing accidents from happening.
The inlet ball valve of the water turbine can be used in media containing sediment water.
This valve can only be used as a shut-off valve and cannot be used to regulate flow.
The water turbine inlet ball valve has the characteristics of low fluid resistance, simple spherical structure, small volume, and light weight.
Easy to operate, quick switch, only need to rotate 90 ° from fully open to fully closed, convenient for remote control.
Easy maintenance, the sealing ring of the water and electricity ball valve is movable, making disassembly and replacement more convenient.
When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
Long service life.
