Electric Valve
Electric valve is a device that drives the valve to open and close by electric motor. It is widely used in various industrial and civil fields, such as metallurgy, chemical industry, petroleum, natural gas, heating, ventilation and air conditioning, automatic control, etc. The following are some application scenarios of electric valves:
1. Fluid control in industrial production: electric valve can be used to control the flow, pressure and temperature of liquid, gas and steam to meet the needs of industrial production.
2. Oil and natural gas industry: electric valves can be used in oil and natural gas exploitation, processing, transmission and storage to control flow and pressure and ensure production safety and efficiency.
3. Chemical industry: electric valve can be used for fluid control in chemical production, such as acid-base solution, gas and liquid reactant control, to ensure the safety and efficiency of production.
4. Heating, ventilation and air conditioning system: the electric valve can be used to control the water flow, air flow and temperature in the heating, ventilation and air conditioning system to meet the requirements of the indoor environment.
5. Automatic control system: electric valve can be used with automatic control system to realize automatic control and adjustment of fluid flow, pressure, temperature and other parameters.
In short, electric valves are widely used in industrial and civil fields, which can improve production efficiency, ensure product quality and improve production safety.
