Gas Stove Extinguishing Device

The flameout protection device is a device that automatically shuts off the gas source to ensure your safety when the gas stove is accidentally extinguished (for example, when boiling water overflows and extinguishes the fire when cooking), mainly divided into two types: thermoelectric type and ion induction type. The state has mandated that gas stoves have flameout protection, so you should never buy one without flameout protection. (Of course, as long as you don't go to the small market, you can't buy one without flameout protection.)

Thermoelectric type: It is the principle of opening and closing the solenoid valve by sensing the temperature through a thermocouple and generating a thermoelectric potential. This flameout protection device is a set of thermocouples and solenoid valves that only control one gas path, with a high safety factor: that is, if one of them is damaged, it will not affect the normal use of the other burner. It is stable and reliable, and generally does not require an external power supply. . However, it has a certain thermal inertia, so that the current output by the thermocouple cannot disappear immediately when the flame is extinguished, and the response to accidental flameout is slow. Generally, it takes about 5-10s to close the gas valve, but this leakage will not cause any security issues. Most of the cooktops of brand manufacturers use this method, among which the flameout protection device produced by the Spanish company 0KALI is the most stable.
