Abstract
The present application provides a ball valve. The ball valve includes a valve body, a valve seat, and a valve rod. The valve seat is installed on the valve body. One end of the valve rod is rotatably installed in the valve body, and the other end of the valve rod extends out of the valve body via the valve seat. A position of the valve rod penetrating through the valve seat is provided with a limiting convex ring. An end of the valve seat away from the valve body is provided with a convex edge. And an end of the convex edge towards the valve body abuts against the limiting convex ring to limit the valve rod from separating from the valve body.
