Description

The coil is sleeved on the solenoid valve body and can be separated. The valve core is made of ferromagnetic material. The magnetic force generated when the coil is energized attracts the valve core, and the valve core pushes the valve to complete the opening or closing. 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 little to do with the valve action. the difference. 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. For the same coil , when the AC current of the same frequency is added, 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. ), the iron core is attracted to form a closed magnetic circuit. That is, when the inductance is designed in the maximum state. The heating is normal, but the iron core cannot be smoothly pulled in when it is energized, the coil inductance is reduced, the impedance is reduced, and the current is increased accordingly, which will lead to excessive coil current and affect the life. , it can't even be pulled in normally, so that the coil is often in a state with less impedance than normal when it is energized, which may be the factor of the coil.
