Double 9mm Hole Diameter ABS Solenoid Modulator Valve Magnetic Coil

This pulg-type solenoid coils is a automotive solenoid coil, used in WABCO type 4421977102 ABS Modulator Valve. In general, the solenoid valve coil has a beautiful shape and a compact internal structure. It is a device that generates action by Faraday's law, generates magnetic lines of force after being energized, and then attracts two metals inside under the action of magnetic lines of force. At present, with the continuous development of science and technology, after continuous improvement and improvement by manufacturers, it has been in TCXO circuit and RF transceiver module, VCO, Bluetooth module, communication equipment, LCD TV, inkjet printer, photocopying machine. It plays an irreplaceable role in many fields such as display monitors, video recorders, CD players, automotive electronics, and medical machinery.

Solenoid valve coil classification
There are many kinds of solenoid valves, such as gas control, liquid (such as oil, water), most of which are solenoid valve coils on the valve body, can be separated, the valve core is made of ferromagnetic material, relying on it to energize the coil When the magnetic force is generated, the valve core is pushed and opened by the valve core to open or close. The solenoid valve coil can be taken separately. It is used to control the opening and closing of the pipeline.

The solenoid valve coil is mainly composed of a pilot valve and a main valve, and the main valve adopts a rubber sealing structure. When the position is normal, the movable iron core seals the pilot valve port, the pressure in the valve chamber is balanced, and the main valve port is closed. When the coil is energized, electromagnetic force is generated to attract the movable iron core, and the medium in the main valve chamber is leaked from the pilot valve port, so that a pressure difference is generated, the diaphragm or the valve cup is quickly lifted, the main valve port is opened, and the valve is presented. The passage is gone. When the coil is de-energized, the magnetic field disappears, the movable iron core is reset, the pilot valve port is closed, and the pressure in the pilot valve and the main valve chamber is balanced, and the valve is closed again.

The role of the solenoid valve coil
The movable iron core in the solenoid valve coil is attracted by the coil when the valve is energized, and drives the spool to move, thereby changing the conduction state of the valve; the so-called dry or wet only refers to the working environment of the coil, and the valve action is not large. the difference.

However, we know that the inductance of an air-core coil is different from the inductance of the iron core in the coil. The former is small and the latter is large. When the coil is connected to alternating current, the impedance generated by the coil is not Similarly, for the same coil, when the same frequency of alternating current is applied, the inductance will change with the position of the core, that is, its impedance changes with the position of the core. When the impedance is small, the current flowing through the coil will increase.
