Valve (Famen) is a control component in the fluid conveyor system, which has functions such as cutting, adjusting, diversion, preventing inverse flow, stabilization, diversion or overflow pressure.The valve for the fluid control system, from the simplest cut -off valve to the various valves used in extremely complicated self -control systems, has a variety of specifications 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.
Valve purchase
I. Selection process 1. The effect of clear valve in the neutral and equipment of the pipe system is to cut off fluids, diversion, conditioning, and still ensure safety.2. Concluding the operating conditions of the valve: the variety of pipeline intermediary texture (whether it can have acid and alkali and corrosion strength), operating pressure, operating temperature, and so on.3. According to the conditions of the working conditions and the connection method of the valve and the pipeline: flange, thread, welding, etc.4. Methods to operate valves according to the type of valve diameter and their own needs: manual, worm, electric, pneumatic or liquid, electrical linkage or electrical linkage.5. Determine the valve housing and internal information based on the operating conditions: cast steel, forging steel, high, low alloy steel, stainless acid steel, Harbin alloy, Inkimi, Montanor alloy, two -phase phase, two -phase phasesStainless steel, titanium alloy, etc.
