Suitable for Kawasaki SKM6 pilot safety solenoid valve coil

What is the magnetic force of solenoid valve coil related to?

The solenoid valve coil is mainly composed of a pilot valve and a main valve, and the main valve adopts a rubber sealing structure. In normal position, the movable iron core seals the pilot valve port, the pressure in the valve cavity is balanced, and the main valve port is closed. When the solenoid valve coil is energized, the electromagnetic force will attract the movable iron core, and the medium in the main valve cavity will leak from the pilot valve port, resulting in pressure difference, the diaphragm or valve cup will be lifted up quickly, the main valve port will be opened, and the valve will be in a passage. When the solenoid valve coil is powered off, the magnetic field disappears, the movable iron core is reset, and the pilot valve port is closed. After the pressure in the pilot valve and the main valve cavity is balanced, the valve is closed again.

There are many kinds of solenoid valve coils that can control gas and liquid (such as oil, water and gas). Most of them are wrapped around the valve body, which is very convenient to take off. The valve core is made of ferromagnetic materials, and the magnetic force generated when the coil is energized attracts the valve core, which pushes the valve to open or close. It is used to control the opening and closing of pipelines.

Operating principle of solenoid valve coil:

The solenoid valve coil is based on Faraday's law. When it is energized, magnetic field lines will occur, and then under the effect of magnetic field lines, the two metals inside will attract each other and then act.

There are many kinds of solenoid valve coils and solenoid valves, such as solenoid valves operated by tap water, medical devices, pneumatic valves, steam, low-temperature liquid nitrogen, corrosive acid-base media, massage beds, drinking fountains, refrigerators, water heaters, cars, water heaters, credit card showers, washing machines, water purifiers, solar energy, cleaning equipment, test equipment, CNG equipment, gas equipment, hydraulic system, mining machinery, compressors, etc.

What is the relationship between the size of magnetic force of solenoid valve coil and:

The size of the magnetic force of the solenoid valve coil is related to the wire diameter and number of turns of the coil and the magnetic conductivity area of the magnetic steel, that is, the magnetic flux. The DC electromagnetic coil can be pulled off the iron core; If the communication fails, the communication coil will be unplugged from the iron core, which will lead to the surge of coil current and burn the coil. There is a short-circuit ring inside the communication coil iron core to reduce oscillation, and there is no need for a short-circuit ring inside the DC coil iron core.
