Analyze the working principle of electric valve _ operation of electric valve

Analyze the working principle of electric valve:

The electric valve has a larger working force than the electric valve. The electric valve can be adjusted in speed, simple in structure and easy to maintain. Due to the cushioning characteristics of the gas itself during operation, it is not easy to be damaged due to jamming, but it must have a gas source and its control. The system is also more complex than electric valves.

Pneumatic valves are responsive, safe and reliable, and many manufacturers with high control requirements set up compressed air stations for pneumatic instrument control components. Electric is to electricity. And a device that can control its flow.

First, what is an electric valve: The electric valve is simply to control the valve with an electric actuator to achieve the opening and closing of the valve. It can be divided into upper and lower parts, the upper part is the electric actuator and the lower part is the valve.

There are two kinds of electric valves, one is the angular stroke electric valve: the electric actuator with the angular stroke is used with the valve of the angular stroke to realize the 90 degree internal rotation control of the pipe fluid on and off; the other is the linear electric valve: The straight-stroke electric actuator is used with a straight-stroke valve to achieve fluid on and off of the valve on-board action control. Usually used on a highly automated device.

Second, the electric valve operating principle: The electric valve is usually connected by an electric actuator and a valve, and becomes an electric valve after installation and debugging. The electric valve uses electric energy as power to connect the electric actuator to drive the valve to realize the switching and regulating action of the valve. Thereby achieving the switching or regulating purpose of the pipeline medium.

The solenoid valve is a kind of electric valve; the magnetic field generated by the electromagnetic coil is used to pull the valve core, thereby changing the opening and closing of the valve body, the coil is de-energized, and the valve core is returned by the pressure of the spring.

Third, the use of electric valve:

Electric valve: Analog adjustment for pipe media flow in liquid, gas and wind systems, is AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.
