Thermosetting two-way PU series normally closed solenoid valve coil

1. The solenoid valve coil function

The solenoid valve coil is one of the core components of the solenoid valve, and its function is to generate a magnetic field through electromagnetic induction and control the switch of the valve. When the current passes through the solenoid valve coil, a magnetic field will occur, which will attract or push the valve, thus controlling the movement of fluid or gas.

The working principle of solenoid valve coil is to convert electric energy into magnetic energy, so as to complete the control of the valve. In industrial automation control system, solenoid valve coil is widely used in hydraulic, pneumatic, water treatment and other fields, and its stability and reliability are very important to the control of production process.

2. Share the method of judging whether the solenoid valve coil is good or bad

Observe the appearance of the coil: If the appearance of the coil is deformed, aged and cracked, it will probably affect the function and life of the coil.

Measuring resistance value: Measure the resistance value of the coil with a multimeter and other things. If the resistance value exceeds the planned scale, it is clarified that there may be problems such as short circuit or open circuit in the coil, and it needs to be repaired or replaced.

Measuring the size of magnetic force: measure the size of magnetic force of solenoid valve coil with magnetometer and other things. If the magnetic force value is small, there may be a situation that the coil function is not safe and needs to be adjusted or replaced.

Measuring current value: use ammeter and other things to measure the size of the current flowing through the solenoid valve coil. If the current value exceeds the planned scale, there may be problems such as overload, which needs to be adjusted or replaced.

In a word, judging whether the solenoid valve coil is good or not requires comprehensive consideration of many factors such as coil appearance, resistance value, magnetic force size and current value, so as to ensure the function and safety of the solenoid valve coil.
