Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve. Background Art

[0002] The ball valve has become one of the most widely used valves in modern times due to its simple structure, good sealing performance and strong flow capacity. The buried ball valve is used to connect with oil, gasoline, liquefied natural gas, liquefied petroleum gas, and petrochemical pipelines.

[0003] Since the pipeline is buried, the ball valve also needs to be set under the ground, generally in the form of a manhole. When opening or closing the ball valve, it is usually necessary to go down into the manhole or crawl on the ground to turn the rotating handle, which is very inconvenient. Therefore, the utility model proposes a ball valve to solve the above problem. Utility Model Content
