Valve special for chlorine alkali

Abstract

The invention provides a valve special for chlorine alkali. The valve comprises a valve seat at the bottom, a valve ring connected to the upper portion of the valve seat, an adjusting ring connected to the upper portion of the valve ring, a recoil ring arranged above the adjusting ring, a valve flap arranged in the recoil ring, a guide sleeve arranged above the valve flap, a valve cover arranged above the guide sleeve, a spring arranged in the valve cover, a valve rod arranged above the spring, a backpressure base arranged on the upper portion of the valve rod, an adjusting screw arranged above the backpressure base and a valve cover arranged above the adjusting screw. Aiming at the special requirements for conveying of strong acid, strong alkali and other highly corrosive media, the valve special for the chlorine alkali is designed and formed by combining the domestic actual situation of valve application and adopting the novel sealing form and the reliable sealing structure. The valve has the characteristics that the sealing performance is stable, using is safe and reliable, the corrosion resistance is high, the internal leakage and the external leakage of the media are avoided, and operation is convenient.

Description

technical field [0001] The invention relates to a special valve for chlor-alkali, which belongs to the technical field of special valves. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that enables or stops the flow of media (liquid, gas, powder) in piping and equipment and controls its flow. [0003] The valve is a control component in the pipeline fluid conveying system, which is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, throttling, check, diversion or overflow and pressure relief. Valves used for fluid control range from the simplest shut-off valve to various valves used in extremely complex automatic control systems. Valves for industrial pipelines. It can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioacti...

AI Technical Summary

Problems solved by technology

[0004] The medium flowing in the chlor-alkali production pipeline system usually includes strong acid and strong alkali (caustic soda, hydrochloric acid) hydrogen, chlorine gas, hydrogen chloride, acetylene gas, etc. They are all explosive, flammable, toxic, and harmful substances. If valve leakage occurs, it will not only affect Production safety involves personal safety and seriously pollutes the environment
