The coil of the solenoid valve refers to the inductor, which is wound by wires one by one, and the wires are insulated from each other. Inductance can be divided into fixed inductance and variable inductance, fixed inductance coil referred to as inductance or coil.
In order to better distinguish it from the solenoid valve coil AC, we changed the solenoid valve coil DC to a green light. The material of the circuit board has also been slightly upgraded, and higher-quality materials are used to make it safer and more convenient.
The movable iron core in the solenoid valve coil is attracted and moved by the coil when the valve is energized, which drives the valve core to move, thereby changing the conduction state of the valve; the so-called dry type or wet type only refers to the working environment of the coil, and has nothing to do with the valve action. big difference.
However, the inductance of an air-core coil is different from the inductance after adding an iron core to the coil. The former is smaller and the latter is larger. When the coil is connected to alternating current, the impedance generated by the coil is also different. When the same coil is added with the same frequency of alternating current, the inductance will vary with the position of the iron core, that is, its impedance will vary with the position of the iron core. When the impedance is small, the current flowing through the coil will increase.
