[0002] A ball valve is a valve in which the opening and closing element (the ball) is driven by a valve stem and rotates around its axis. It can also be used for fluid regulation and control. The hard-sealed V-shaped ball valve, with its strong shear force between the V-shaped ball core and the carbide-clad metal seat, is particularly suitable for media containing fibers and tiny solid particles. An externally controlled ball valve, on the other hand, utilizes an external control source, such as hydraulics or a motor, to drive the valve stem.

[0003] The prior art includes a utility model with publication number CN217539679U, which discloses a new externally controlled sealed ball valve. The patent adopts a shell, and the inner cavity wall of the shell is rotatably connected to the ball valve body. The left and right ends of the shell are connected to pipes, and a flange is provided at the end of the pipe away from the shell. The middle part of the upper end of the ball valve body is fixedly connected to a valve stem, and the lower end of the valve stem is rotatably connected to the shell. An L-shaped rod is fixedly connected to the left side of the upper side of the left pipe, and the right end of the upper side of the L-shaped rod is fixedly connected to a motor, and the upper end of the valve stem is fixedly connected to a mounting plate. The utility model relates to the technical field of ball valves. The new externally controlled sealed ball valve solves the problem that the existing externally controlled sealed ball valve is inconvenient to manually control or automatically control the ball valve, and the manual control ball valve is not comfortable to hold. It solves the problem that the existing externally controlled sealed ball valve is inconvenient to manually control and automatically control the ball valve, and the hand is not comfortable to hold when manually controlling.

In addition, the adjustment structure used is set on the valve stem of the ball valve and is lifted by a thread. Since the thread needs to be rotated step by step to push the sleeve to the motor drive end, the separation and installation operations of the equipment are inefficient. Utility Model Content
