Description
Technical field: [0001] The invention relates to a valve manufacturing technology, in particular to a technology of reducing water flow resistance of a valve. Background technique: [0002] Most of the sealing surfaces of the sealing pads in the existing valve clack are flat. In the working process, there is a defect of large resistance to water flow, resulting in large power loss. Summary of the invention: [0003] The technical problem to be solved by the present invention is to provide a water flow resistance reduction technology that can effectively overcome the above-mentioned defects and has a small power loss of the valve flap. [0004] The technical solution adopted by the present invention to solve the technical problem is a valve flap reducing water flow resistance technology, which mainly includes the following steps: the sealing surface of the sealing gasket provided between the valve flap body and the flow guide cap is a conical surface. [0005] Due to the adoption...
