Background

Ball valves are widely used in oil field well heads, oil tanks, gathering and transportation stations, oil and gas pipeline systems and petrochemical industries, and people usually control the flow of liquid and gas by arranging valves such as ball valves, and most of the ball valves can be opened and closed freely. For management, some ball valves are prohibited from opening and closing at will, such as a pipe main gate, and a locking device is required on the ball valve to prevent others from opening the valve without permission and stealing oil and gas. In order to achieve the anti-theft effect, various anti-theft ball valves appear in the market, and some anti-theft ball valves are complex in structure and inconvenient to use; some anti-theft ball valves have simple structures and poor anti-theft effects.

The utility model discloses a patent is granted utility model patent of bulletin number CN202469200U and is disclosed a area lock theftproof ball valve, this theftproof ball valve include the lock sleeve, and on the lock sleeve was located between valve rod support and the valve rod and was fixed in the circumference inside wall of valve rod support through the fixed pin, still was equipped with the locking device by key control between lock sleeve and the valve rod. The locking device is also complicated in structure, and includes a displacement pin, a locking pin and a telescopic spring. When the anti-theft ball valve is used, a manager controls the locking of the ball valve through the key, and the key is collected when the anti-theft ball valve is not used, so that the anti-theft effect is achieved. The anti-theft ball valve has a complex structure, and the ball valve is not easy to open when a key is lost in the using process, so that troubles are brought to a user.
