The structure of the solenoid valve is mainly composed of coil, core, small spring seat, rubber valve, etc.

 When the coil is energized, the electromagnetic force overcomes the elastic force of the small spring, and the iron core is sucked on and the electromagnetic valve is opened. When the coil is powered off, the core is ejected under the action of a small spring, and the population is sealed again, so the solenoid valve is closed. The coil is energized to attract the core, and the magnetic force is greater than the pressure difference on the upper and lower end of the core.
