Embodiment Construction

[0008] A manufacturing process of a valve flap with a diversion cap mainly includes the following steps: the valve flap body is provided with a diversion cap through connecting bolts, and the top surface of the diversion cap is made into a streamlined curved surface. The structure of the valve flap with a diversion cap manufactured by the present invention will be further described in detail below in conjunction with the accompanying drawings. Referring to the accompanying drawings, the disc body 4 is connected to the diversion cap 1 through connecting bolts 5, a gasket 3 is embedded between the disc body 4 and the diversion cap 1, and the sealing surface of the gasket 3 is a conical surface. Wherein, the middle part of the disc body 4 is provided with a "Y"-shaped sealing ring. Wherein, the top surface of the diversion cap 1 is a streamlined curved surface to reduce water flow resistance, thereby reducing power loss.

Description

Technical field: [0001] The invention relates to a manufacturing technology of a valve, in particular to a manufacturing process of a disc of a valve. Background technique: [0002] In the existing valve clack, the valve clack body is connected with the pressure plate through connecting bolts. The top surface of the platen is usually planar. During its working process, it has the disadvantage of high resistance to water flow, which leads to large power loss. Invention content: [0003] The technical problem to be solved by the present invention is to provide a manufacturing process of a valve clack with a diversion cap that can effectively overcome the above-mentioned defects and has a small power loss. [0004] The technical solution adopted by the present invention to solve the technical problem is a manufacturing process of a valve disc with a diversion cap, which mainly includes the following steps: the disc body is provided with a diversion cap through connecting bo...
