Technical Field
[0001] This utility model relates to the field of sealing ball valve technology, and in particular to a sealing ball valve with anti-theft self-locking function. Background Technology
[0002] A ball valve is a type of valve in which the valve stem drives the valve to rotate around the valve axis. It can also be used for fluid regulation and control. Ball valves are classified according to their driving method as: pneumatic ball valves, electric ball valves, and manual ball valves. A sealed ball valve is a type of ball valve with a sealing gasket of a corresponding type installed inside the ball valve.
[0003] However, existing ball valves consist of multiple components. During use, thieves can operate the ball valve to steal internal components without obstruction. There is a need for a structure that can help to easily lock the drive component to the ball, making it easy to disassemble and lock, thereby improving convenience and security. Therefore, it is necessary to design a ball valve with anti-theft self-locking sealing. Utility Model Content
[0004] The main purpose of this utility model is to provide a self-locking, anti-theft ball valve that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

A connecting pipe is fixedly connected to the upper surface of the right ball shell. A platform is fixedly connected to the upper surface of the connecting pipe. A retaining shell is attached to the upper surface of the platform. An adjustment port is opened on the upper surface of the retaining shell. A return spring is fixedly connected to the inner wall of the adjustment port. A self-locking rod is fixedly connected to one end of the return spring. A limit plate is fixedly connected to the lower surface of the self-locking rod. A groove is opened on the outer surface of the self-locking rod near the limit plate. A self-locking ball is engaged on the outer surface of the groove. A retaining hole is opened on the outer surface of the retaining shell near the groove. A connecting port is opened on the upper surface of the ball. A retaining platform is opened on the inner wall of the connecting port.
[0007] In order to achieve the purpose of driving the ball to rotate and realize the function of the ball valve, as a ball valve with anti-theft self-locking sealing of this utility model, a drive actuator is installed on the upper surface of the self-locking rod, a protective cover is sleeved on the outer surface of the drive actuator, a limit bar is fixedly connected to the lower surface of the protective cover, a limit hole is opened on the upper surface of the retaining shell, and a limit cap is threadedly connected to the outer surface of the limit bar.
[0008] In order to achieve the purpose of external secondary locking, the present invention provides a self-locking sealing ball valve with anti-theft features four limiting holes arranged in a circular array. A chain is fixedly connected to the outer surface of the limiting cap, and a small lock is movably connected to the outer surface of the chain.
[0009] In order to achieve the purpose of assisting multi-directional self-locking, the size of the connection port of this utility model is adapted to the size of the casing, and there are four locking holes arranged in a ring array. The number and position of the locking holes are adapted to the number and position of the self-locking ball.
[0010] In order to improve the sealing performance of the connection between the middle flange and the right ball shell, the outer surfaces of the left and right ball shells are fixedly connected to a middle flange, and a plug ring is fixedly connected to the outer surface of the middle flange near the right ball shell.
