Working principle of high pressure ball valve
High pressure ball valve it has 90 degrees of rotation, the ball, a circular hole or passage through its axis. Ball valve in the pipeline is mainly used to do cut off, distribution and change the direction of the medium flow, it only need to use the rotation of the 90 degrees of operation and a small torque can be closed tight. Ball valve is the most suitable for use, but the recent development has been designed to make it a throttle valve and control the flow of the use, such as V type valve.
The main characteristics of the high pressure valve is compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, not easy to be medium erosion, easy operation and maintenance, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., widely used in various industries. Ball valve body can be whole, it can be a combination of.
Advantages of high pressure ball valve:
1 full bore ball valve fluid resistance small, little flow resistance.
2 simple structure, small size, light weight.
3 tight and reliable. It has two sealing surface, and the sealing surface of the ball valve is widely used in all kinds of plastic, good sealing, can achieve complete sealing. In the vacuum system has also been widely used.
4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.
5 easy maintenance, simple structure of the valve, the sealing ring is generally active, more convenient to replace the demolition.
6 in the fully open or fully closed, the ball and valve seat sealing surface and the medium isolation, the medium through, will not cause erosion of the valve sealing surface.
7 wide range of sizes, from small to a few millimeters, a few meters from the high vacuum, high pressure can be applied.
8 due to the opening and closing of the valve in the process of cleaning, it can be used in the medium with suspended solids.
