inquiry@ato.com.cnDifference Between Electromagnet and Solenoid Valve
The solenoid valve and the electromagnet are similar to each other. Indeed, they have many similarities and also have differences between them. The similarities and differences between the solenoid valve and the electromagnet are briefly analyzed as below.
Solenoid valve
The solenoid valve is an industrial tool used to control basic automatic elements of fluids. As an actuator, it is used to adjust the direction, flowing quantity, speed and other parameters of the medium in the industrial control system. The solenoid valve can be used together with different circuits to realize expected control. The control precision and flexibility can also be ensured.
The solenoid valve is made up of several gas circuits and valve elements, which can control the switch-on and switch-off of different gas circuits. How many valve elements the solenoid valve has means how many positions the solenoid valve has. How many gas circuits the solenoid valve has means how many ports the solenoid valve has. Therefore, the solenoid valves can be divided into two-position and three-port, two-position and four-port, two-position and five-port, three-position and five-port, etc.
Different solenoid valves play a different role in different positions of the control system. The most commonly-used solenoid valves include the single-direction valve, safety valve, directional control valve, speed-adjusting valve, etc.
The solenoid valve has an airtight cavity, and there is the through-hole in different positions. Every hole is connected with different pipelines. The movement piston is at the center of the cavity. On two sides of the cavity are two electromagnet. The magnetic coil electric valve body is attracted to the corresponding side. By controlling the movement of the valve body, different oil outlets are turned on or turned off. The inlet is constantly-open. The liquid oil enters different oil exit pipes. Relying on the oil pressure, the piston of the oil cylinder is driven, which can further drive the piston pole. Next, the piston pole drives the mechanical device. Thus, through control of the electromagnet current, the mechanical movement is controlled.
The solenoid valve can be divided into the gas solenoid valve, water solenoid valve, oil solenoid valve, etc.
Electromagnet
Electromagnet is a device which can generate electromagnetism after switch-on. The iron core is wrapped externally with the electric conduction winding consistent with its power. The coil connected with the current has the magnetism like the magnetic iron. Generally, we make the coil into the bar shape or horseshoe shape to facilitate magnetization of the iron core. Besides, in order to ensure immediate demagnetization of the electromagnet after disconnection with the power, we usually adopt materials, such as soft iron or silicon steel, with fast demagnetization to make the electromagnet. The electromagnet made up of these materials will have magnetism after getting connected with power, and lose its magnetism upon disconnection with power.
Electromagnet has found wide applications. Invention of the electromagnet has greatly improved the power of the generator. The electromagnet made up of these materials will have magnetism after getting connected with power, and lose its magnetism upon disconnection with power. The iron core in the middle moves repeatedly along with magnetism and spring to realize one function, such as the self-acting clutch.
Advantages of the electromagnet: Magnetism of the electromagnet can be controlled by switch-on and switch-off. The value of the magnetism can be controlled by the current intensity or the number of coils or through adjustment of the resistance. Its magnetic pole can be controlled by the direction of the current. To sum up, the intensity of magnetism can be changed; the existence of magnetism can be controlled; the magnetic pole can be changed; the magnetism might disappear along with disappearance of the current.
Generally speaking, the solenoid valve has the electromagnet in its solenoid but not just that. But the electromagnet plays an important role in solenoid valve's working as we can seen from the above.
