Abstract

The invention discloses a ball valve. The ball valve comprises a valve body, wherein a mounting hole is formed in the valve body, a left channel pipe and a right channel pipe are fixedly mounted at the left end and the right end of the valve body, an end cover is fixedly mounted at the lower end of the valve body, a ball core is rotationally connected into the mounting hole, a driving shaft is mounted in the valve body, and at least one flat key is mounted on the driving shaft; at least one password disc is mounted on the driving shaft in a sleeving mode; and the at least one password disc isrotated, and the driving shaft can be controlled to slide up and down along the valve body, so that the connection between the driving shaft and the ball core is controlled. The ball valve is simple in structure and more reliable in anti-theft structure.

Description

technical field [0001] The invention belongs to the technical field of pipeline valves, in particular to a ball valve. Background technique [0002] Ball valve is a commonly used valve in the chemical industry, gas transmission, urban gas supply, and tap water supply pipelines. It has simple structure, reliable switch and long service life. Therefore, it is widely used in the above fields. Ordinary structure ball valves can be directly controlled by users as needed, and have control freedom and flexibility for direct users, but they lose control for gas supply and water supply management units. When the front-end engineering construction is not completed or the gas and water supply conditions are not met, after the valve is misoperated or operated without authorization, there will be safety hazards of tap water and gas leakage, or the risk of being stolen. The existing means of preventing unauthorized opening of the valve mainly includes designing the valve stem pulling in...
