Ball Valve Definition

1. Ball valve is a valve that uses a ball with a circular channel as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action. The opening and closing part of the ball valve is a sphere with holes, which rotates around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the channel. Ball valves are mainly used to open and close pipelines and equipment media.

2. The ball valve is evolved from the plug valve. It has the same lifting action of rotating 90 degrees, the difference is that the cock body is a sphere with a circular through hole or channel through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball rotates 90 degrees, all spherical surfaces should be present at the inlet and outlet, thereby truncating the flow. The ball valve only needs to be rotated 90 degrees...

3. It is generally believed that the ball valve is most suitable for direct opening and closing, but recent development has designed the ball valve to make it throttling and controlling flow.
