The valve is used in the field of power plants, mainly for the pipeline of various systems in power plants, cut off or connect the pipeline medium.
In the domestic power industry, it is customary to adjust the water flow and pressure of the device called a "regulating valve", installed in the boiler's water jet desuperheater spray pipe, feed pipe, high plus hydrophobic pipeline, feed water bypass, etc., to adjust the feed water flow or spray water flow and pressure; adjust the steam flow and pressure of the device called "pressure reducing valve", divided into electric pressure reducing valve and pneumatic pressure reducing valve, installed in the boiler's temperature and pressure reducing system, soot blowing system, oil pipeline heating system and air preheater system
Common valves are globe valves, gate valves, three-way valves, check valves, regulating valves
Globe valves are generally installed in water and steam pipelines, mainly for hydrophobic, maintenance and drainage, shut-off, etc;
Gate valves are generally installed in water and steam pipelines to play a major role in isolation, normal operation is fully open state;
A three way valve is installed between the pressure gauge and the pressure gauge elbow, for the pressure gauge
The control valve mainly plays the role of flow regulation;
A check valve is installed in steam and water pipelines, as an installation device to automatically prevent the backflow of media. Part of the function of the check valve can be categorized as safety protection.
