Description

Technical Field

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

[0002] A butterfly valve is a simple regulating valve that opens, closes, or regulates the flow of a medium through the rotation of a disc-shaped opening and closing member around the valve shaft. This opening and closing member, commonly known as a disc, rotates around its own axis within the valve body, achieving the desired opening, closing, or regulating function. Butterfly valves are widely used to control the flow of various fluids, including air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media, primarily for shutoff and throttling purposes.

[0003] When using a valve, if accumulation occurs and the valve control cannot solve the blockage, the valve needs to be disassembled to complete the dredging. In order to reduce the disassembly process, a valve with a rotating part to dredge the blockage position is designed, which requires the use of this multifunctional butterfly valve.
