Difference Between Electromagnet, Solenoid Valve and Solenoid

BESSER

Solenoid coil

A solenoid is a coil wound on a skeleton, and there is a magnetic field when it is energized, which can induce or pull the iron core in the middle. Now there are hollow coils, which are wound with self-adhesive enameled wire and do not need a skeleton. It is also a kind of solenoid.

The solenoid cannot complete a functional action alone, and requires other media to cooperate. In engineering, solenoids are also referred to as converters that convert energy into linear motion.

The solenoid-operated valve is a comprehensive element, and the most important component in it is the electromechanical solenoid. An electromechanical solenoid is an electromechanical element that can be used to operate a pneumatic valve or a hydraulic valve.

A solenoid switch is a relay that uses an electromechanical solenoid to operate an electrical switch.

 

Electromagnet:

A device that generates electromagnetism when energized. A conductive winding that matches its power is wound on the outside of the iron core. This current-carrying coil has magnetism like a magnet. It is also called SOLENOIDS.

It is usually made into a strip or hoof shape to make the iron core easier to magnetize. In addition, in order to demagnetize the electromagnet immediately after power-off, it is made of soft iron or silicon steel material with faster demagnetization. Such an electromagnet has magnetism when it is energized, and the magnetism disappears after the power is off. The middle iron core reciprocates along with the magnetism and the spring to realize a function. Such as automatic clutch.

 

The electromagnetic valve:

Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automation basic component used to control fluid and belongs to actuator. Used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium.

The solenoid valve can cooperate with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, and speed control valves.

 

The solenoid valve has a closed cavity with through holes at different positions. Each hole is connected to a different pipeline. The middle of the cavity is a moving piston and two electromagnets on both sides. Which side of the magnet coil will be energized by the valve body Where it is attracted, by controlling the movement of the valve body to open or close the different oil discharge holes, and the oil inlet is normally open, the hydraulic oil will enter the different oil discharge pipes, and then the oil pressure will push the cylinder The piston, the piston drives the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current on and off of the electromagnet.

Solenoid valve can be divided into air valve, water valve, oil valve and so on.

Combined with the above explanation, the difference between electromagnet, solenoid valve and solenoid is: solenoid valve is solenoid plus a valve, electromagnet is solenoid plus auxiliary shell iron core. The electromagnet is an extension of the solenoid, and the solenoid valve is an extension of the function of the electromagnet.
