What is the use of extinguishing protection device in gas stove?
Flame extinguishing protection device is that when the flame is accidentally extinguished by wind, soup and other reasons, the flame extinguishing protection device will automatically close the gas source, so that gas leakage will not be caused by the gas stove.
The principle of extinguishing protection device is that when the flame is unexpectedly extinguished, the induction probe on the extinguishing protection gas stove can't sense the combustion signal, that is, the temperature. If the controller can't get the signal, it will automatically cut off the maintenance current to the safety valve, leading to the closure of the safety valve, thus cutting off the gas passage.
Many citizens reflect that they dare not let go after putting out the fire to protect the gas stove, otherwise the flame will be extinguished immediately. This is because the quenching probe does not sufficiently sense the flame temperature, the ventilation solenoid valve can not be opened smoothly, and the gas can not pass through, so the flame will be extinguished. The correct method is to press the knob continuously after ignition for 3-5 seconds and release the hand, so that the probe temperature meets the requirements, and the magnetic valve opens and burns normally.
Standard for checking gas stove of extinguishing protection device: ignite the switch of stove fittings, burn for 1 minute, adjust the flame to the minimum fire, blow out the flame artificially, and you will hear the sound of gas "nourishing", then start to time, and emit "voice" at the knob within 60 seconds, indicating that the extinguishing protection device has been started, and then check with leak detector. If there is no leakage at the furnace head, it proves that the fire extinguishing safety device is effective.
