[0002] A butterfly valve, also known as a flap valve, is a regulating valve with a simple structure. A butterfly valve that can be used for on-off control of low-pressure pipeline media refers to a valve whose closing member is a disc that rotates around a valve shaft to achieve opening and closing. As a prior art of butterfly valves, a Chinese patent (publication number: CN219432473U) discloses a butterfly valve that is easy to adjust, including a housing, a turntable and a telescopic column. A disc plate is provided inside the housing, one end of the disc plate is connected to one end of a rotating column by welding, and a second bevel gear is provided at one end of the rotating column away from the disc plate. The second bevel gear The wheel meshes with the first bevel gear, and the first bevel gear is connected to one end of the turntable by welding. The telescopic rod is pulled out of the limit hole by the pull rod, and then the telescopic column is pulled by the handle until the telescopic column moves to an appropriate length, and then the telescopic rod is released. Through the resilience of the elastic member, the second elastic member pushes the telescopic column back to the inside of the limit hole, and the telescopic column is limited to prevent the telescopic column from entering the inside of the support column again.
