Solenoid valve is a magnet coil connected to the power supply caused by magnetic attraction to get rid of the elastic yellow push working pressure, on a magnet coil, simple structure, low cost, only need to complete a variety of solenoid valve power switch; Automobile pressure relief valve electric regulating valve is based on the motor to drive the seat, to promote the valve core position, electric regulating valve and divided (off) valve and regulating valve.

The double-position on-off valve refers to the two-position type, namely the open type and the fully closed type. The regulating valve of the respiratory electromechanical magnetic valve is installed on the electric valve positioner, which is adjusted according to the closed-loop control to make the power stability of the turbine pressure relief valve gate valve in one position.

The main uses of electric regulating valve and solenoid valve are compared.

Solenoid valve: for liquid and gas lines in the power switch operation, it is two DO operation. Usually used for small and medium size pipe operation.

Electric regulator: it is used to adjust the analog quantity of the total material flow in the software pipeline of liquid and gaseous daily wind system. It is operated by AI. Operation of large and medium-sized gate valve daily wind system software, also can use electric control valve to do double power switch operation.

Solenoid valve: only as the amount of switch, DO operation, only for small pipe operation, more common in DN50 and below pipeline.

Solenoid valve: can have AI feedback data signal, can be operated by DO or AO, respiratory mechanical magnetic valve is more common in large pipes and electric wind valves.

I. Power switching mode:

According to the solenoid coil drive solenoid valve, only on or off, switching power supply posture time is short.

The electric regulator is generally driven by a motor, which must be input for a certain period of time when it is turned on or off before adjustment.

Ii. Work Content:

Ordinary commodity solenoid valve index is not big, solenoid valve working pressure difference is not big. Solenoid valve driven by solenoid coil is more vulnerable to damage by working voltage impact. Equivalent to the power switch, is on, off two effects.

Electric governor generally uses motor drive, more resistant to working voltage impact. Solenoid valve is quick to open and close, generally used for small total flow and small working pressure, the provision of higher frequency of power supply in the area. The tubing pressure of the electric regulating valve can be adjusted, the situation is open, the solenoid valve is closed, half closed.

General solenoid valve can turn off the power supply for verification, electric control valve to such action must be added to the calibration equipment.

Three, available processing process:

Some special processing requirements of electromagnet.

Electric governor is used at adjusting commonly, also have the action of switch.
