What is a ball valve repair

To understand what is the ball valve repair, the first thing to understand: What is a ball valve

Just use the ball valve 90-degree rotation operation and a small torque can be closed tightly. The body cavity of full equality for the media to provide a little resistance, through the flow channel. Generally considered the most suitable ball valve opening and closing done directly used, but recent development has been designed to make the ball a throttle valve and flow control purposes. The main characteristics of the ball valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas work in general media, but also for poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene and so on. Ball valve body can be integral, it can be modular.

To further understand the ball valve ball valve repair but also understand the working principle of the evolution and

And principle of evolution

Ball valve is evolved by the plug. It has the same movement rotated 90 degrees to mention, is the cock body is different sphere, there are circular holes or channels through its axis. Sphere and the ratio should be such that when the ball is rotated 90 degrees, in the import and export office should be fully rendered sphere, thus cutting off the flow

Advantages

1, fluid resistance small, the drag coefficient with the length of the barrel of the same.

2, simple structure, small size and light weight.

3, Close and reliable ball valve sealing surface material widely used plastic, sealing in a vacuum system has also been widely used.

4, easy operation, opening and closing rapidly, from fully open to fully closed as long as the rotation 90 °, to facilitate remote control.

5, easy maintenance, simple ball valves, seals are generally activities, the removal replacement is more convenient.

6, in the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, the medium through, will not cause erosion of the valve sealing surface.

7, for a wide range of a few millimeters in diameter from small to large as a few meters, from high vacuum to high pressure can be applied

Brief description of the above, perhaps you have a preliminary understanding of what is a ball valve repair
