What does gas stove flameout protection mean

The gas stove flameout protection is to close the gas channel when the gas stove is not working, or when the gas is accidentally turned off in the middle of the use process (the wind blows out, the soup is extinguished, and the ignition is unsuccessful), so as to avoid gas leakage accidents. Common gas stove flameout protection devices, mainly thermocouples.

flame-out protection device and self-priming valve flame-out protection device.

At present, there are basically two types of flame-out protection devices of gas stoves, one is to use thermocouples to generate electric potential by heating, through electromagnetic induction, so that the solenoid valve is in the state of opening the valve, if the thermocouple can not sense the flame, the solenoid valve is closed, so as to achieve the effect of flame-out protection; There is also the use of ion induction, through the pulser to control the closure of the solenoid valve, so as to achieve the purpose of flameout protection.

This answer applies to Fotile.

Most brands of gas stove models such as Vantage and Haier.

The flame out protection device of the gas stove is very simple, it can detect the flameout state of the gas stove in real time, when the flame of the gas stove is extinguished due to accident, the flameout protection device can cut off the gas source in time, avoid gas leakage, and avoid gas accidents.

The flame-out protection device is installed in **?

The flame-out protection device of the gas stove is installed in the burner head of the gas stove. There are generally two needles in the stove head of a gas stove, one is an ignition device used for ignition, and the other is a flame-out protection device.

Therefore, if you find that there is only one needle on the stove head of the gas stove when you buy a gas stove, it means that it must not have a flame-out protection device.

In addition, we can also test whether the gas stove has a flame-out protection device through the method of ignition test: light the stove, burn for 1 minute, adjust the flame to the minimum fire, artificially blow out the flame, you will hear the gas "Zizi" gas sound, and then start the timer, within 60 seconds the knob makes a "click" sound, indicating that the flame-out protection device has been activated, if there is no leakage, it proves that the flame-out safety device is effective.

Further judgment is as follows: 1. The flame-out needle must be combined with the solenoid valve, pulse igniter and other components, if it is only an independent flame-out needle, it is only a decoration. 2. If the gas stove disconnects the gas within 60 seconds, it means that the gas stove is protected by flame-out. Classification of flame-out protection devices for gas stoves Flame-out protection devices are mainly divided into:

There are two types: thermoelectric and ion-inductive. Thermoelectric: Safety factor.

High, even if a common fault occurs on one side, it will not interfere with the normal operation of the other burner. Ion induction: A common failure of one burner will result in the failure of all hobs.

The second is high power consumption, and the battery usually needs to be replaced once every 1-2 months.

Common sense of gas stove maintenance: be sure to open the window or exhaust fan to ensure the flow of indoor ventilation during the whole application process, if the gas stove is not used for a long time, the battery needs to be removed and the battery should be replaced regularly, and the flamethrower should be cleaned regularly with a soft brush or steel needle.

After cleaning, be sure to dry before installing, and the rubber hose should not be used for more than 18 months.

1.Check if there is a flame-out pin on the gas stove. There are usually two pointers on a gas stove, one is an ignition needle and the other is a flame-out needle. If there is only one ignition pin on the furnace, there is no flameout protection. You can't choose this one at the time of purchase.

2.Whether the gas stove can be automatically cut off within 60 seconds after it is turned off. The difference between having flame-out protection and not having flame-out protection is whether the gas can be automatically cut off.

3.When purchasing, you should check whether there is an induction probe on the burner, and there should be a flame-out protection device under the induction probe. When the flame is extinguished, the gas furnace is qualified if it can automatically cut off the gas within 60 seconds.

4.If the store doesn't provide an ignition, you'd better check it yourself after you get home. First, light the gas stove and then blow the fire out.

If you hear a "pop", it means that the automatic flame-out protection device has been activated and the valve has been closed. This is a qualified flame-out protection device.

The way to remove the automatic protection of the gas stove is to remove the sealing cap of the solenoid valve in the gas circuit.

The way to remove the flame-out protection device of the stove is to remove the sealing cap of the solenoid valve in the gas circuit to turn off the flame-out protection function. However, it is recommended that it is best to keep the flame-out protection device to avoid the collapse of the cavity.

Precautions when using a gas stove:

1. The gas source is different, and the gas stove used should also be different, which should be noted when purchasing. If the air source you use has changed, be sure to ask the original manufacturer to modify your stove accordingly before using it.

2. The gas rubber pipe is easy to age and rupture, and the interface and bend of the pipe should be checked frequently, and if there is damage, it should be replaced immediately, or replaced once every 1 2 years. It is best to choose rubber pipes that are resistant to oil and pressure.

3. When using the gas stove, people should not stay away. In case of leakage or extinguishing of the flame due to accidental reasons (wind blowing, water overflow, etc.), the main switch of the gas source should be turned off immediately, the doors and windows should be opened, and the ventilation should be quickly ventilated.

4. Users who use artificial gas must always clean the fire holes on the fire cover to avoid blockage. <>

The reason may be that the ion induction extinguishing starts to extinguish the fire, and the current gas stove even has the OEM flame extinguishing protection. Because the state is mandatory. Generally, there are two types of flame-out protection.

1. Thermocouple extinguishing: using the physical properties of metal, it belongs to temperature difference induction, and the flame-out protection action is controlled by temperature induction. When the temperature is lower than a certain temperature, the air supply is immediately cut off, which is an immediate reaction, and the general extinguishing time is about 5 to 10 seconds.

2. Ion induction extinguishing: Using the photoelectric properties of the flame, when the flame deviates from the induction needle, it will immediately make a judgment in seconds and cut off the gas source within 5 to 8 seconds. The problem of poor circuit contact, which is easy to ignore, but often encountered in many old users, is mainly to check whether the positive and negative poles of the battery box are rusty, whether the line has poor contact, if there is, the rust needs to be removed, and the line is accurately connected.

Overvoltage protection, many gas stoves have overpressure protection function, once the overpressure is not started, then it is necessary to change a pressure reducing valve to try it, and the pipeline is blocked, which is a very common problem, once the pipeline is blocked, it is necessary to check the gas valve, generally speaking, you can smell the smell of coal and the gas stove is not on fire, it is likely to be gas blockage, and then it needs to be sparse. Or the micro switch is damaged, this is a very small place in the gas stove, but it is more difficult to repair than the usual fault, generally speaking, it is not recommended that the owner repair it himself, this is a fine, professional work, so please ask a specialist to solve. The last is that the ignition needle is dirty, the kitchen is a place that is easy to get dirty, it is easy to be contaminated with oil, etc., the gas stove is placed for too long, the ignition needle is easy to be stained by oil, then you need to clean the ignition needle of the grease, and then try to ignite.

Identify the gas stove used with automatic flame-out protection device:

1. Douse the gas stove with water, if the gas stove automatically cuts off the gas within 60 seconds, it is a qualified product. Otherwise, it is a substandard product.

2. Merchants confuse the concept of alarm device and automatic flame-out protection device, the main function of the alarm device is to test whether the gas is leaking, and the automatic flame-out protection device is to cut off the gas immediately after the gas leakage is found. Therefore, the simple alarm device can not effectively eliminate potential safety hazards, but only plays a warning role.

It may be that the fire is relatively small, when the calorific value of the flame is lower than the temperature required by the thermocouple, the gas stove flame-out protection device is turned on, and the power is automatically turned off, and the fire can be turned on a little larger to solve this problem.

Thermocouples are used as temperature measuring elements for temperature measurement, indication and control by matching with instruments. The thermocouple flame-out device of the household gas stove is to cooperate the specially designed thermocouple with the solenoid valve to play the role of flame-out protection. When the gas stove switch is ignited, the thermocouple is heated to generate an electromotive force, which indicates the cooker to work.

At this time, the electromotive force supplies power to the solenoid coil through the wire, and when the combustion switch is opened, the solenoid valve pressed down by the outer connecting rod is maintained in position, so that Qilu keeps it smooth and the stove burns normally. When the flame goes out for some reason in the cooktop or the flame is too small, the thermocouple probe cools down, the electromotive force is lost (weakened), the solenoid coil loses current, and the valve reset causes the gas path to close.

At this time, it can be solved by turning up the flame, if it is still not solved, you can check the working condition of the thermocouple, and the failure of the thermocouple directly affects the patency of the gas; Whether the ventilation duct is blocked, and the blockage of the pipeline will also lead to flameout; whether the battery should be replaced; Dirty ignition needles and misaligned positions can also lead to improper ignition.

"Gas stove flame-out protection" means that when the flame of the gas stove is extinguished by wind or soup, the gas stove will turn on the flame-out protection to prevent the gas from continuing to leak.

Precautions for the use of equipment: 1. Clean up the traces of the gas stove in time after use, and you can use a clean soft cloth to wipe the surface to avoid the accumulation of oil stains.

2. The equipment cannot be used, it may be caused by the gas running out, it needs to be recharged in time, it may be the hardware failure of the equipment, it is recommended to ask professionals to repair it; It may be that the ignition device is out of power and needs to replace the battery.

3. The equipment should be installed on a flat desktop to avoid affecting the use effect.

4. After the equipment is used, the valve should be closed in time to avoid gas leakage, and during daily use, professionals should be asked to regularly check the air tightness of the pipeline.
