Description

Valve ball and valve rod Technical Field The utility model relates to the field of valve accessories, in particular to a valve ball and a valve rod. Background A ball valve is one of valves, and is mainly used in a pipeline to cut off, distribute and change the flow direction of a medium. Ball valves are generally composed of a valve body, a ball body, a valve rod and the like, wherein the ball body is a ball valve opening and closing piece, and the valve rod is used for driving the ball body to rotate. The valve rod drives the ball body to rotate around the axis of the ball valve, so that the ball valve is opened and closed, and cutting, distributing and changing the flow direction of the medium are completed.
