The butterfly valve has a simple structure and is mainly composed of a valve body, a butterfly disc, a valve stem and a sealing ring. The butterfly disc rotates around the valve shaft and controls the flow and flow of the fluid by rotating the angle.

[0003] At present, in order to ensure the sealing of the butterfly plate, the seals assembled around it need to be replaced regularly. However, the existing butterfly plates are generally one-piece structures, and the replacement operation of the seals is cumbersome and not convenient enough. Therefore, a butterfly valve butterfly plate is proposed, and the seals are easy to replace to ensure the use effect of the valve body. Utility Model Content

[0008] At the same time, the fixing holes on the two side surfaces of the support ring allow the first butterfly plate and the second butterfly plate to be disassembled and assembled with bolts through the corresponding disassembly holes, so as to facilitate the later disassembly and replacement of the first sealing ring and the second sealing ring, and the operation is convenient.

[0009] Specifically, the first butterfly plate and the second butterfly plate are respectively located on both sides of the support ring, and the first butterfly plate and the second butterfly plate are both fixed to the fixing holes by means of disassembly hole bolts.

[0010] By adopting the above technical solution, the support ring is supported between the first butterfly plate and the second butterfly plate.

[0011] Specifically, a valve stem passes through the center of the support ring.

[0012] By adopting the above technical solution, the valve stem is used to control the rotation of the butterfly plate body.

[0013] Specifically, a first clamping groove and a second clamping groove are respectively provided on the surfaces of the first butterfly plate and the second butterfly plate.

[0014] By adopting the above technical solution, the first clamping groove and the second clamping groove are used to facilitate the clamping sleeve to adhere the first sealing ring and the second sealing ring respectively.

[0015] Specifically, a first sealing ring and a second sealing ring are adhered to the periphery of the first card slot and the second card slot respectively, and the first sealing ring and the second sealing ring are both made of polytetrafluoroethylene.
