Thermoelectric flameout protection magnetic valve protection device



First, the use of flameout protection solenoid valve


The flameout protection solenoid valve is used on a burning appliance that uses liquefied petroleum gas, natural gas, artificial gas, etc. as fuel.


Second, the basic structure and principle of the flameout protection solenoid valve (refer to GB12203-90 or CJ30-99 standard)


1. Basic structure of flameout protection solenoid valve: flameout protection solenoid valve It is a protection device consisting of two parts: the sensor element thermocouple and the control element solenoid valve.


2. Schematic diagram of the structure of the flameout protection solenoid valve:

3. Working principle of flameout protection solenoid valve:


a. Flameout protection solenoid valve When the burner flame is burned, the flameout protection solenoid valve sensor element thermocouple is heated by the flame to generate current, so that the solenoid valve core and the armature remain in the suction state, and the flameout protection solenoid valve keeps the gas passage normal. Gas supply.


b. Flameout protection solenoid valve When the burner flame is extinguished, the flameout protection solenoid valve causes the current generated by the thermocouple to drop, so that the iron core and the armature of the solenoid valve are loosened, the gas passage is automatically cut off, and the flameout protection solenoid valve is prevented from leaking.
