Pay attention to daily maintenance of solenoid valve

Solenoid valve is the electromagnetic control of industrial equipment, used in industrial control system to adjust the direction of the medium, flow, speed and other parameters. Solenoid valve can be matched with different circuits to achieve the desired control, and control precision and flexibility can be guaranteed.

Principle of solenoid valve: when energized, the solenoid coil generates electromagnetic force to lift the closing part from the seat and the valve opens; When power is cut off, the electromagnetic force disappears, the spring presses the shutoff on the seat, and the valve closes.

Daily maintenance of solenoid valve:

1, leakage plug, leakage easy to control, safe use. Internal and external leakage is an element that endangers safety. Other automatic control valves usually extend the valve stem, by the electric, pneumatic, hydraulic actuator control valve core rotation or movement;

2, this is to solve the long-term action stem dynamic seal leakage problem; Only the solenoid valve is electromagnetically sealed in the electric control valve in the magnetic sleeve of the iron core is completed, there is no dynamic seal, so easy to plug leakage.

3, electric valve torque control is not easy, easy to produce internal leakage, or even pull the stem head; Solenoid valve structure is easy to control internal leakage until reduced to zero. Therefore, solenoid valve is particularly safe to use, especially suitable for corrosive, toxic or high and low temperature media.

4, the solenoid valve itself simple structure, low price, compared with the control valve and other types of actuator is easy to install and maintain. What is more remarkable is that the automatic control system is much simpler and cheaper. As the solenoid valve is the switch signal control, and the industrial computer is very convenient to connect.

5, solenoid valve response time can be as short as a few milliseconds, even if the pilot solenoid valve can be controlled in a few milliseconds. Because of its own loop, it is more sensitive than other automatic control valves. Well-designed solenoid valve coil power consumption is very low, is an energy-saving product; Also can do as long as the trigger action, automatic valve position, usually do not consume electricity.
