working principle
Pressure control is called electric control valve. Electric ball valve, electric disc valve and intelligent control valve are all electric valves. In fact, the torque of electric valve is large. In the form of large adjustment, the electric valve can roughly control the opening. The realization principle is to stop when the motor rotates.
application
The electric control valve is suitable for flow regulation in computer monitoring system. Generally, it is used in unattended thermal stations. The electric control valve is composed of valve body, driving mechanism and transmitter. Temperature control valve is a kind of equipment which can adjust the flow rate by itself through the temperature sensing package, without external power supply; while the electric control valve generally needs single-phase 220 V power supply, which is usually used as the actuator of computer monitoring system (regulating flow). Electric control valve or temperature control valve is the most important equipment of flow regulation in heating system, and others are its auxiliary equipment.
structure
The electric control valve is composed of electric actuator and regulating valve after debugging and installation.
