Description

Fully sealed valve based on Hall principle

technical field

The utility model relates to the technical field of sealing valves, in particular to a fully sealing valve based on the Hall principle.

Background technique

Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The valve is the control component in the fluid delivery system, with the functions of cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, diversion or overflow pressure relief, etc. Function, the valves used in fluid control systems, from the simplest cut-off valves to various valves used in extremely complex automatic control systems, there are quite a variety of varieties and specifications.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom-made valves, etc. according to the material.

At present, the existing gas delivery valves can only deliver a single gas. When transporting complex gases or mixed gases, gases with different densities, such as helium, are difficult to pass through, which brings inconvenience to the gas delivery work.
