What are the types of solenoid coils?

There are many kinds of solenoid valves, such as those that control gas and liquid (such as oil and water). Most of them are wrapped around the valve body and can be separated. 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. The solenoid valve coil can be taken down by itself. It is used to control the opening and closing of pipelines.

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 coil is energized, 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 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.

The solenoid coil refers to the inductor. The guide wires are wound one by one, and the wires are insulated from each other, and the insulating tube can be hollow, and it can also include iron core or magnetic powder core, which is called inductance for short. Inductance can be divided into fixed inductance and variable inductance. The fixed inductance coil is wound around the insulating tube by wires, and the wires are insulated from each other. The insulating tube can be hollow and can also include iron core or magnetic powder core, which is called inductance or coil for short. L indicates that the units are Henry (H), Milli Henry (mH) and Micro Henry (uH), and 1h = 10 3mh = 10 6UH.

Inductance l

The inductance l indicates the inherent characteristics of the coil itself, regardless of the size of the current. Except for the special inductance coil (color-coded inductance), the inductance is generally not specially marked on the coil, but with a specific title.
