Thermosetting two-position two-way Baode solenoid valve coil BD-A-03

Function of solenoid valve coil

Solenoid valve is composed of electromagnetic coil and magnetic core, which contains one or several.

The valve body of the hole. When the coil is energized or de-energized, the operation of the magnetic core will cause fluid.

Pass through the valve body or be cut off to change the direction of fluid. solenoid valve

The electromagnetic components of are composed of fixed iron core, moving iron core, coil and other components; valve body

Part consists of slide valve core, slide valve sleeve and spring base. The electromagnetic coil is straightened.

Connected to the valve body, the valve body is enclosed in a sealed tube to form a simple

Clean and compact combination. There are two-position three-way and two-way solenoid valves commonly used in production.

Four-way, two-way and five-way etc.

Let's talk about the meaning of two-position solenoid valve first: for solenoid valve, it is

Electrification and deenergization are the opening and closing of the controlled valve. Electromagnetic cutting

There are many kinds, including controlled gas and liquid (such as oil and water), and most of them

The valve body is covered by a coil and can be separated, and the valve core is made of ferromagnetic material.

The valve core is attracted by the magnetic force generated when the coil is electrified, and is pushed by the valve core.

The valve is opened or closed. The coil can be taken down separately. This solenoid valve is

Used to control the opening or closing of gas pipeline. Movable iron in solenoid valve coil

When the valve is energized, the core is attracted by the coil to move, which drives the core to move and change.

On-state of the valve.

The causes of burning loss are generally as follows

1, coil quality problems

2, turn off the overvoltage strike

Wear; 3. The power supply voltage is too high;

4, repeated impact, frequent on-off overcurrent or

superheat

5. Instability in installation and excessive mechanical vibration lead to short wire break due to coil wear.

Road, back electromotive force caused by overvoltage to wear the coil is very likely, electric.

The potential is equal to the inductance of the coil multiplied by the current change rate (for time). Usually the reverse connection is made.

Diodes can easily solve such problems (diode withstand voltage is higher than coil current)

The voltage is 1.5-2 times, and the current is 1,5-2 times greater than the coil current.
