Convenient-to-install pressure ring for valve

Abstract

The invention relates to the technical field of valves, and discloses a convenient-to-install pressure ring for a valve. The convenient-to-install pressure ring comprises a valve main body. A flange plate is fixedly arranged at the top of the valve main body. A valve cover is fixedly arranged at the top of the flange plate. A threaded hole extending into the valve main body is formed in the valvecover. A valve rod penetrating through the valve cover and extending into the valve main body is in threaded connection with the interior of the threaded hole. An extrusion groove is formed in the topof the flange plate. According to the convenient-to-install pressure ring for the valve, the valve cover is provided with limiting blocks extending into a limiting groove, the purpose of limiting thevalve cover is realized; clamping springs are arranged in grooves and are provided with clamping heads extending into clamping grooves to realize the purpose of installing a pressure ring body conveniently; and a through hole is formed in the flange plate and provided with an extrusion rod to realize the purpose of installing and replacing the pressure ring conveniently.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a pressure ring for valves which is convenient for installation. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters of conveying media. According to their functions, they can be divided into shut-off valves, check valves and regulating valves. Valves can be used to control air, water , steam, various corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow, the valve is also divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel valves, chrome molybdenum valves according to the material Vanadium steel valves, duplex steel valves, plastic valves and non-standard customized valves, etc. [0003] The spacer ring of the valve is also called the pressure ring, which acts to evenly distribute the axial press...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pressure ring for valves that is easy to install, which has the advantages of easy installation and replacement of the pressure ring, and solves the problem that when the pressure ring is installed on the existing valves, the valve cover is removed by turning the screw. However, there are many screws fixing the end cover, which leads to the problem that the efficiency of replacing the pressure ring is low
