The structure of the ball valve: it is composed of one valve body and two valve covers combined with ball core. The ball core is connected by the valve rod, and the axis can be rotated 90 degrees to realize the function of opening and closing. It is mainly used for pipeline switch, emergency cut-off, and ball core V-shaped opening can also be designed to achieve flow regulation function.
