Maintenance method of gas stove

We use the gas stove almost often, and we also need its help when cooking. Do you know how to fix the gas stove if there is a problem? The following is the maintenance method of gas stove that I arranged for you, hoping to help you.

Maintenance method of gas stove 1. Abnormal flame.

1, there is fire separation or fire separation: at this time, it is likely that the air door is too small, so just adjust the air door. Or because the pressure of the gas stove is too high, it can be adjusted appropriately at this time. If it can't be solved, you need to ask a professional gas stove maintenance master to solve it.

2. Other phenomena: Sometimes there is no open flame for a long time, or the flame is too small, so it is necessary to change the position of the air outlet pipe. Also, when paying attention, if you repair the gas stove yourself, you must make clear the signal and some basic information of the gas stove.

3, there is a slight tempering phenomenon: this is likely to make the air pressure too low, just increase the degree of the air valve. Or the design is unreasonable, the diameter of the fire hole is too large and the use space is too small.

4. There is air leakage or odor: at this time, it is necessary to check whether the trachea is broken, or whether the joint of the valve is aging and needs to be replaced in time, or if there is no ignition, just restart it directly.

Second, you can light a fire and put it out as soon as you let go.

Because of the current national regulations, all gas cookers must be equipped with accidental flameout protection devices, which are related to flameout protection devices. Working principle of flameout protection device: when the fire is ignited, the thermocouple is heated by the fire, so that the heat generates electricity, and then the electromagnetic coil in the valve body generates suction to open the valve and make the gas come out for combustion. When the fire goes out or the thermocouple is not burning and there is no electricity, the valve will automatically close and the gas cannot be discharged, thus achieving the purpose of safety. This phenomenon can be overhauled from the following points:

1, did the fire reach the thermocouple after ignition? If not, the fire cover may not be properly placed, the thermocouple hole may be blocked by sundries or water, and the thermocouple may shift or sink. Take it off.

2. After ignition, lead the fire to the thermocouple. The thermocouple itself may be damaged and can be replaced. It may be that the interface between thermocouple and valve body is in poor contact.

Third, tempering, that is, hearing the snapping sound.

Generally, the throttle is too small, so the gas can't get out of the fire cover and burn in the inner cavity of the furnace head. Just adjust the throttle properly.

Fourth, the knob can't be pressed.

Generally, the knob rod of the valve body assembly is not installed in the center of the panel hole, and the bottom of the knob is stuck, so the panel can be adjusted.

Five, ignition does not catch fire

This problem is actually very common because there are many reasons for this phenomenon. Specific phenomena and solutions. Let me introduce you one by one.

1, the air pressure is too high, which has an impact on EDM: at this time, simply adjust the air source and reduce the air pressure. The output cable is damaged, so it needs to be close to the ignition: replace it with a new one, which can't be done.

2. The power cord is loose or the internal structure of the igniter is damaged in a large area: replace the igniter directly. Pulse igniter has no voltage: it is necessary to install a new battery or directly replace the battery.

3. The ignition nozzle is too large, which has an impact on the electric spark: just replace a nozzle; There is foreign matter in the hose nozzle: it is best to clean it up.

4. The pulse ignition switch has slight poor contact: it can be simply repaired or replaced. Insufficient gas pressure on the gas switch: you can see if the gas company has stopped gas. The ignition cable is not connected to the magnetic head: it only needs to be stuck with glue or tape.

Tips for Daily Cleaning and Maintenance of Gas Stove Inspection of Gas Hose

As a place to transport fuel, gas hose can not be ignored, and it is often dangerous because of aging and cracking. First, you can feel whether the hose is soft by hand, and try to tear it off by hand. The gas itself is colorless and tasteless, in order to prevent accidents. In particular, hydrogen sulfide is added to the gas, which tastes a bit like rotten eggs. So as to simply judge whether there is leakage. After closing the gas meter valve, there is still an odor, so it can be judged that there is natural gas leakage after closing the gas meter valve.

At the same time, if the hose hardens and cracks, it is easy to fall off without the fixing of the throat belt. The hose connecting the pipeline should be replaced regularly, and both ends of the hose should be tied tightly with throat straps instead of metal wires. After the hose is installed, you can check it with detergent boiled water, and then smear it on gas pipes, gas meter hoses, cock switches and other places that are prone to air leakage. If there is foam, it means that there is air leakage.

Check whether the fire hole is blocked.

Did you find that the flame in the stove became smaller when cooking? There will also be tempering and other phenomena. The decrease of flame in the cooker is mostly caused by the blockage of fire holes and nozzles. A fire covered with oil pollution and impurities. Some users are not careful when cooking food. Occasionally overflow or foreign matter falls into the fire hole, blocking the burner fire hole, preventing the mixed gas of gas and air from flowing out and making the flame smaller.

Before cleaning the gas stove, be sure to disconnect the gas source of the gas pipe to avoid injury. First, remove the support frame of the gas stove. Then slowly take out the fire cover. Generally, the fire outlet of the furnace head adopts three-layer design.

After opening, you can see evenly distributed fire holes, which can be alleviated by cleaning them with toothpicks or thin things. If the hole of the fire cover is designed with an Al-Mn alloy burner, it can be removed and cleaned with water or detergent.

Because the gas will contain some impurities, sulfides and other substances to varying degrees, there will be dirt in the fire hole of the fire cover, which will make the fire hole smaller after long-term use. If the flame is compressed by gust or overflow, it will cause the flame to retreat and then backfire. In order to avoid this situation, the fire hole should be cleaned in time after being used for a period of time. After cleaning the burner, the flame burns more smoothly, the firepower is more concentrated, and it will not be scattered everywhere.

Daily cleaning of igniter

The igniter of the gas stove is the most easily broken place. As an ignition system, gas stove mainly uses piezoelectric ceramic ignition and pulse continuous ignition besides manual ignition with matches or ignition with matches. As soon as the microswitch is turned on, a series of electric sparks can be generated to excite the fuel to realize ignition. See if the pulse battery is dissolved by high temperature and covered by dirty matter, which makes it impossible to transmit electric energy to the fire eye.

Observe whether the spark of the gas stove is soft and weak, and whether the discharge frequency is obviously slower than before. If that's the case, our battery is low, so we need a new battery to solve it. It was because the igniter was broken before, so it was quite dangerous to use matches to assist ignition. Warm reminder, the igniter is broken, so you must find a professional to replace it in time.

Gas stove surface cleaning

At present, the countertops of gas stoves are relatively clean, and the common countertops on the market include stainless steel, glass panels and enamel panels. Many clean friends will clean the surface after cooking to remove oil stains and other pollutants spilled during cooking. Relatively speaking, gas stoves with glass panels and stainless steel panels are relatively easy to clean.

There are many kinds of decontamination cleaners on the market that can help users remove stubborn stains. Just spray the detergent on the greasy place before cleaning, and then gently wipe it with a cloth for a while, and it will be as clean as new. But remember not to clean the glass panel with steel balls, because scratches will occur when scrubbing, which will cause the protective layer to crack, reduce the strength and make the countertop more prone to burst.
