The main purpose of the gate valve

Gate valve is a common type of valve, mainly used to cut off or connect the flow of fluid. Due to its simple structure, good sealing performance and wide range of applications, it is widely used in various industrial and civil pipeline systems. The following are the main uses of gate valves:

1. Water supply system

Purpose: Used in pipelines in urban water supply and building water supply systems to switch water flow.

Features: Due to good sealing, it can effectively prevent water leakage.

2. Sewage treatment

Purpose: In sewage treatment plants and sewage pipelines, it is used to cut off or connect the flow of sewage.

Features: It has good corrosion resistance and is suitable for sewage media.

3. Oil and gas industry

Purpose: Used in oil and gas pipelines to cut off or connect media.

Features: Able to withstand high pressure and high temperature, with good sealing performance.

4. Chemical industry

Purpose: Used in pipeline systems of various chemical media in chemical production processes.

Features: Choosing suitable materials (such as stainless steel, alloy steel) can effectively resist corrosion.

5. Power industry
Use: Used to control the flow of fluids in the steam and cooling water systems of thermal power plants and nuclear power plants.
Features: Able to withstand high temperature and high pressure, and adapt to harsh working conditions.
6. Shipbuilding industry
Use: Used in various piping systems on ships, including water supply, fuel, drainage, etc.
Features: Requires compact structure, good corrosion resistance, and adapts to marine environment.
7. Food and pharmaceutical industry
Use: Used to transport and control pure media in the production process of food, beverages and medicines.
Features: The material is required to be hygienic and non-toxic, easy to clean and disinfect.
8. Building heating system
Use: Used to cut off or connect hot or cold water in the heating and cooling systems of buildings.
Features: Requires high temperature resistance, high pressure resistance, and good sealing.
9. Mining industry
Use: Used to control water flow in the drainage and water supply systems of mines.
Features: Requires wear resistance and adapts to harsh working conditions.
10. Firefighting system
Use: Used to cut off or connect water flow in firefighting water systems.
Features: It needs to have the ability to open and close quickly to ensure timely supply of fire water.
The main advantages of gate valves are small flow resistance, good sealing performance, and easy opening and closing, but they are not suitable for regulating flow. When selecting a gate valve, you should choose the appropriate material and type based on specific working conditions, such as medium properties, pressure, temperature, etc., to ensure its safety and reliability.
