Thermocouple on the gas stove play "in the condition of abnormal flameout, thermocouple thermoelectric potential disappear, gas solenoid valve in the line shut down the gas under the action of a spring, lest produce risk"
Normal use process, thermocouple continuous thermoelectric potential ensures that the gas solenoid valve is always in a state of open, ventilation.
Attach a simple introduction:
Thermocouple flame-out protection device consists of two parts, thermocouple and electromagnetic valve, ignition heating the thermocouple thermoelectric potential, electromagnetic valve to open the ventilation, normal combustion. When abnormal flameout, thermocouple thermoelectric potential disappear, electromagnetic valve closed protective.
