Gas stove induction needle function gas stove induction needle working principle

The gas stove induction needle is an important part of the flameout protection. When the fire is on, the induction electricity is generated, and when the power is off, the valve is automatically closed. Adapted to the gas leakage of the gas stove when the gas stove is blown out by the wind, thus causing unsafe factors. The induction needles of gas stoves are generally divided into two types, one is an ion induction needle, and the other is a thermocouple induction needle. Let's take a look at the function of the gas stove induction needle and the working principle.

Gas stove induction needle

The normal gas stove should have two needles. When the fire is blown out by the wind or the water is poured out, the gas supply will be cut off automatically to ensure safety. But now there are some in the market, and there are also businesses that require manufacturers to produce a fake sensor pin to deceive consumers. You need to know what is the use of the gas stove's flameout protection device to know the necessity of the gas stove induction needle.

In general, when the gas stove is normally burning, the micro-current in the flame can ensure continuous ventilation, and when the flame is unexpectedly extinguished, the ion-extinguishing sensor will induce current in 2 seconds, but the sensitivity is too high. Inconvenience, for example, only the natural breeze blows the flame away from the induction needle, which will cause the solenoid valve to cut off the air source, so that it has to be re-ignited. Therefore, the induction needle is added with an intelligent judgment function of 5 to 8 seconds to effectively distinguish the flame. The temporary deviation and accidental flameout have allowed the stove to achieve a safe upgrade. According to reports, the flame-stopping needle technology is expected to become the new safety standard for national gas appliances next year.

Gas stove induction needle replacement

Disassemble the panel and the burner, remove the three screws that secure the burner from the bottom of the gas stove with a Phillips screwdriver, and then use a vise to remove the copper induction screw on the burner. The induction needle is an important part of the flameout protection. It generates induction electricity when it is on fire and automatically closes the valve when it is powered off. When the gas is blown out by the wind, the gas stove gas leaks, which causes unsafe factors. There are two types of induction needles for gas stoves: ion induction needles and thermocouple induction needles. If you are only not sure, you can also ask for an after-sales installation.

Gas stove induction needle working principle

1, thermocouple protection, is to burn to the thermocouple by the fire, the thermocouple is heated to conduct electricity to the solenoid valve, gas passage, normal combustion. When the thermocouple is protected, it takes a few seconds to switch the ignition.

2, the induction needle protection is based on the electrical conductivity of the fire to complete the protection. When the fire burns to the induction pin, the fire conductive induction pin conducts electricity (both are equivalent to the switches in the circuit) and the solenoid valve opens. The gas passage can be burned normally. The principle of the flameout protection device gas stove is that when the flame is accidentally extinguished, the induction probe on the flameout protection gas stove does not sense the combustion signal, ie the temperature, and the controller will automatically cut off the holding current to the safety valve when the controller fails to obtain the signal, resulting in The safety valve is closed, thereby shutting off the gas passage.

The above content is the introduction of the gas stove induction needle and the related working principle of this small series for everyone's reference. I believe that after reading this article, we will have a certain understanding of the gas stove induction needle, I hope to be able to Give everyone some help.
