The ball valve came out in 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure has rapidly developed into a main type of valve in a short period of 40 years. In the developed countries of the west, the use of ball valves is increasing year by year. In China, ball valves are widely used in oil refining, long-distance pipeline, chemical, paper, pharmaceutical, water conservancy, power, municipal, steel and other industries, which play an important role in the national economy. The ball valve has the action of rotating 90 degrees, the cock body is a sphere, and a circular through hole or a passage passes through its axis. The ball valve is used in the pipeline to cut, distribute and change the flow direction of the medium. It only needs to be closed with the operation of 90 degrees of rotation and a very small moment of rotation. The ball valve is most suitable for switching and shut-off valves, but the development of the ball valve has recently been designed to make it throttling and controlling flow, such as V ball valve.
