Solenoid valve is a pure iron with U-shaped laminated or U-type soft ferrite core column (armature)

Of the electromagnet. It has a magnetic field generated after power, can be connected to the spool of the connecting rod, so that the gas valve inlet opening, loss of power by its own spring force can automatically reset the role of sealing gas stomata to ensure that gas will not spill. Gas stove in the press the knob ignition, the first by the thimble in the valve body to open the top of the solenoid valve, when the combustion is normal, the thermocouple both ends of the electromotive force (voltage), the solenoid valve was energized to maintain suction to ensure the release of hand gas Of the conduction; when an accidental flameout, the thermocouple no flame without electromotive force generated, the release of the solenoid valve, sealed gas path, to ensure the safety of use
