[0002] The butterfly valve is a commonly used type of valve, mainly used to control the flow of fluids such as gases, liquids, and oils. The working principle of the butterfly valve is to open or close the valve by rotating the butterfly plate. The butterfly plate is usually the same diameter as the pipeline. When the butterfly valve is fully open, the butterfly plate is parallel to the fluid flow direction, with less resistance; when closed, the butterfly plate is perpendicular to the fluid flow direction, thus cutting off the flow.

[0003] However, during the use of the butterfly valve, the butterfly valve often receives a large impact force, resulting in deformation at the connection of the butterfly valve, making the butterfly valve unable to rotate well, or causing the center of the butterfly valve to shift, resulting in leakage.

[0004] In view of this, the utility model proposes a novel butterfly valve. Content of the Utility Model
