AI Technical Summary

Technical Problem

The seal ring fixing method of existing marine valves is fixed by the abutment between flanges, which leads to inconvenience in installation operation and is prone to deviation of the seal ring position, affecting the corrosion resistance of the sealing connection.

Method used

A marine valve structure including a valve shell, flange, sealing ring, limiting groove, retardation plate and support spring is designed. Through the fitting connection between the flange and limiting groove, combined with the elastic connection between the retardation plate and support spring, the positioning and support of the sealing ring on the flange is realized.

Benefits of technology

This design improves the performance between the sealing ring and the flange, enhances the sealing and anti-corrosion effect of the valve when connected and used, and facilitates the installation and use of the sealing ring.

Abstract

The utility model relates to the technical field of marine valves, in particular to an anti-corrosion marine valve which comprises a valve shell, an operation box is arranged on the surface of the valve shell, a rotating handle is movably connected to the outer surface of the operation box, a butterfly plate is movably connected to the inner side of the valve shell, and flange plates are fixedly connected to the two sides of the valve shell. A sealing ring is connected to the outer surface of the flange plate in an embedded mode, and a connecting groove is formed in the surface of the sealing ring. Through the connection of the abutting plate and the supporting spring, the abutting supporting effect between the abutting plate and the connecting groove is achieved, the supporting effect on the acting position of the sealing ring on the flange plate is achieved, the use performance between the sealing ring and the flange plate is improved, and the sealing and anti-corrosion effect of the valve during connection and use is enhanced; the effect of fixing and supporting the acting position of the butterfly plate on the rotating rod is achieved, and the butterfly plate can be conveniently installed, used, disassembled and replaced on the rotating rod.
