The application of gate valves in different industries

1. Oil and Gas Exploration and Transportation
In oil wellheads, gathering and transportation pipelines, and long-distance pipelines, gate valves are used to control the flow rate and pressure of crude oil, natural gas, and associated gas, ensuring the safe and stable exploration and transportation of oil and gas. For example, in distribution stations and booster stations, electric gate valves can precisely adjust the flow rate and pressure of the medium according to dispatching instructions.

2. Refining and Chemical Production
In the pipeline connections between various reactors, towers, heat exchangers, and other equipment in refineries and chemical plants, gate valves are used to control the flow of various chemical raw materials, intermediate products, and finished products. For example, in large-scale chemical plants such as ammonia synthesis and ethylene production, gate valves play a vital role in the control of the technological process.

1. Thermal Power Generation
In the boiler feed water system, steam system, and circulating water system of thermal power plants, gate valves are used to control the flow rate and pressure of feed water to ensure the normal operation of the boiler. For example, an electric gate valve is installed on the outlet pipeline of the feed water pump to accurately control the flow rate of feed water.

2. Hydropower Generation
In the turbine intake, draft tube, and penstock of hydropower stations, gate valves are used to control the on-off and flow rate of water to achieve the normal operation and power generation of the turbine.

3. Nuclear Power Generation
Nuclear power plants have extremely high requirements for the reliability and safety of valves. Gate valves are widely used in various coolant systems, radioactive waste treatment systems, and auxiliary systems within the nuclear island to ensure the safe operation of the nuclear reactor.

(3) Water Treatment Industry
The water treatment industry includes urban water supply, sewage treatment, and industrial water treatment. Gate valves play an important role in these fields.

1. Urban Water Supply and Drainage
In urban water treatment plants, sewage treatment plants, and water supply and drainage pipe networks, gate valves are used to control the flow direction, flow rate, and pressure of water. For example, at the water intake, sedimentation tank, and filter tank of a water treatment plant, gate valves can control the water flow rate and water level according to the requirements of the production process.

2. Industrial Water Treatment
During the industrial production process, gate valves are used to control the water flow of various treatment processes. For example, on the inlet and outlet pipelines of water treatment equipment such as reverse osmosis, ultrafiltration, and ion exchange, gate valves can adjust the water flow rate and pressure to ensure the treatment effect.
