Description

Technical Field

[0001] This utility model relates to the field of valve-related technology, and in particular to a double-sealing structure for a metal ring-sealed regulating valve. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Valves are also classified according to their material, such as cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and non-standard customized valves, thus requiring a double-seal structure such as a metal ring-sealed regulating valve.

[0003] The dual-seal structure of metal ring sealed regulating valves currently on the market has the following problems when used:

[0004] 1. When using a traditional metal ring sealed regulating valve with a double sealing structure, a small amount of liquid may leak out when the valve is fixed to the pipeline, resulting in waste. At the same time, liquid dripping onto the valve surface may cause valve oxidation and reduce the valve's service life.

[0005] 2. In most applications of metal ring sealed control valves with a double sealing structure, it is difficult to install the control valve on the pipeline. At the same time, when the control valve is oxidized after long-term use, it is difficult to disassemble the control valve, which affects the installation efficiency of the control valve.
