Ball valve works by rotating the valve to make the valve flow or occlusion. Ball valve switch light, small volume can made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, not easy to be medium erosion, has been widely used in various industries.
Ball valve and plug valve is the same type of valve, only its closure is a ball, the ball around the center of the body to make a rotation to achieve the opening and closing of a valve.
Ball valve in the pipeline is mainly used to do the cutting, distribution and change the direction of the flow of media. Ball valve is widely used as a new type of valve.
Advantage
1 fluid resistance is small, and its resistance coefficient is equal to that of the same length.
2 simple structure, small size, light weight.
3 close and reliable, ball valve sealing surface material widely used plastic, good 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 maintenance convenient, simple structure, the sealing ring is generally active, demolition and replacement are more convenient.
6 in the fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the media through, will not cause the valve sealing surface erosion.
7 wide range of applications, from small to a few millimeters diameter, large to a few meters, from high vacuum to high pressure can be applied.
Ball valve has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
