What is the red button next to the natural gas meter for, why is there no gas at home if you don t o

I don't know how many friends have ever noticed this little red button, which is located in the gas meter in the kitchen.

Below, under normal circumstances, the top is displayed on, so what is this little button for? Why is there no arrears at home, but the gas is suddenly gone? 1. What is the little red button for? This little red button is called a gas self-closing valve.

Don't look at it small, but its role is very important. If there is a gas leak in our home, we have to rely on this small button to stop the gas output. This small red button can be automatically turned off, and its existence is equivalent to installing a protective device for the gas, protecting the personal safety and property safety of the owner.

Some people say that for safety reasons, the self-closing valve is closed every day when it is not in use, and it is not right to open it when you want to use gas. Frequent opening and closing of the self-closing valve may cause failure after a long time. The gas at home must be used every day, and it is used several times a day, so there is no need to turn it off frequently.

Of course, if we need to be away from the house for a long time, such as a few weeks or more, then we can choose to close the self-closing valve. Second, how can there be no gas at home when the gas bill is paid on time? If you are sure that the family is paying normally, and the neighbors are all gasy, only your home does not have it, then you can check whether the self-closing valve is closed.

If it's turned off, it means that there is a gas leak in your home, but you just didn't notice it. At this time, don't deal with it yourself, be sure to call ** and ask professionals to come to repair. Generally, there are three reasons why gas self-closing valves are automatically closed:

The first is when the pipeline is out of gas; The second is that the gas hose falls off; The third is excessive pressure. If you want to know whether the gas self-closing valve in your home is a normal method, it is actually very simple, we can close the valve in front of the meter first when using gas, and the self-closing valve will automatically close under normal circumstances, and then the gas will be extinguished. Then you can open the valve in front of the meter, and then open the gas stove to see if it can ignite, if it can't ignite, it means that the self-closing valve is normal, otherwise, you have to report for repair as soon as possible.

The red button above the natural gas meter is actually him, he is the air switch or can trip, to your kind of she detects, if a gas is in some danger, this red button will jump, a jump will not have natural gas, so after you press it, the natural gas will come, he is in control of this situation, so as long as you understand, as long as you ask him, there is no problem, and then I think so.

The red button is the front ball valve of the gas meter, which is the gas safety valve, which will automatically fall off and shut off the gas when the gas leaks or the gas density exceeds the standard, so as to prevent the gas from leaking out after the accident, which has a certain safety protection effect. If there is no gas, you can call ** to the gas company and let the master come to check and deal with it.

The red button next to the natural gas meter is called the gas self-closing valve, its function is to close or open the gas ** in the natural gas pipeline, when the red button is closed, even if there is no arrears in the home, but there is no natural gas**, it is normal, and this button needs to be reopened.

If the danger is lifted, i.e. the alarm detects that the gas is no longer leaking, the alarm will automatically disarm. If it still rings, it means that the gas is still leaking. When the gas sensor is in continuous contact with the gas, the resistance of the sensor changes with the change of gas concentration, which generates an electrical signal and outputs various control signals.

When the gas concentration reaches the alarm set value, the gas alarm sends out an audible and visual alarm signal to control the relevant equipment (such as solenoid valves and exhaust fans) to cut off the gas source in time, evacuate toxic, flammable and explosive gases, and inhibit the occurrence of disasters. If the alarm goes off continuously and you can't judge for yourself, it's best to have a professional handle it. Extended Information:

Precautions for the use of gas alarms: 1. Gas alarms cannot be used in environments where the concentration of combustible gas is higher than the lower limit. As can be seen from the working principle of the gas alarm, this catalytic combustion gas alarm is used.

The detection element is the catalytically active element. When the concentration of combustible gas is higher than the lower limit, the detection element in the gas alarm will burn out. In fact, the detection element wears out every time it is operated.

2. Gas alarms cannot be used in places containing sulfur, arsenic, phosphorus, silicon, lead and other elements, because they will poison the detection elements in the instrument, reduce the sensitivity of the instrument, shorten the service life, and even make the instrument serious. If it is not qualified, if a flammable gas containing the above elemental compounds is detected, an anti-poison catalytic combustion gas alarm should be used. 3. The working current (voltage) should be adjusted before the gas alarm is put into use.

The adjusted working current and voltage should be within the range specified in the instrument instruction manual to ensure the normal operation of the gas alarm. At the same time, the detector (probe) is an explosion-proof and explosion-proof equipment, which cannot be used beyond the specified range.

The red button is the switch, and you have to press it to get gas out!

Generally, the gas valve opening state is gas without inserting the card, and the gas will automatically close the valve without inserting the card for three daysGas meterIf the battery is not discharged, the valve will be closed if the display does not light up.

1. The gas meter is damaged and cannot be used normally, and the gas meter needs to be replaced or repaired.

2. If the gas pipeline is blocked, resulting in the gas not coming out, the gas pipeline should be cleaned in time.

3. The pressure regulator is closed, resulting in the inability to produce gas, and the pressure regulator valve will be closed.

Just turn it on. 4. IC card.

The flow rate in the meter has been used up, causing the gas meter to be in a protected state, and the IC card should be replaced.

With a smart gas meter, when the battery in the meter is not charged, the valve in the meter will be turned off. At this point, the battery needs to be replaced and the gas card reinserted, and the gas meter will be back in the gas supply state.

It should be noted that not only will all gas appliances be unusable if the gas meter battery is out of power, but also when the purchased gas meter is exhausted or the gas meter is turned off for some reason, all gas appliances will also be unusable at the same time. So if this kind of problem occurs, you should first try to reinsert the card. in natural gas.

When you can get to the gas stove, check the battery of the gas stove.

Summary. Hello dear! <>

There are 4 reasons why the table does not show after the natural gas recharge is as follows: 1. The operation of the gas sales personnel in the business hall is wrong, the transaction is unsuccessful, and the gas is not successfully sold, you can go to the business hall to read the card to confirm, which is easy to find out, and if there is gas in the card, this possibility is excluded. 2. If the card is not successfully inserted, your own operation error causes the IC card to fail to effectively contact the gas meter, including contrast cards, card insertion is not in place, and card withdrawal in advance.

You need to wait 2 to 3 seconds after inserting the card. 3. The gas meter card holder is damaged, and the IC card information cannot be read normally. 4. If the IC card is damaged, you can go to the business hall to check the IC card.

I hope the above is helpful to you and I wish you a happy life!

The gas was charged, and it was not shown on the meter.

Inflated. What's going on if you still don't need it?

Dear, after recharging, you can't use gas normally, the reason is because the solenoid valve has not been reopened for the prepaid gas brother call meter, they have a solenoid valve that can automatically cut off the gas, and the solenoid valve will automatically close after the gas meter is in arrears, cutting off the gas. When we recharge again, the solenoid valve cannot be automatically opened, and the reason why it is designed is to prevent accidental gas leakage from the bridge height.

So how do I get it next?

Dear, you have to manually restart the gas meter, and if you don't restart, it's still not gasy. Solution: Here according to different gas meters, there are different methods, which can be roughly divided into two categories, one is to press and hold the button on the gas meter after recharging, when you hear the sound of the valve opening, the LCD screen shows that the valve is opened, and the spring return is turned on.

The other type is the gas meter without a button, you need to re-insert the recharge card of the gas meter, insert it into the gas meter, and wait for a few seconds to hear the valve open, and you can do it.

Summary. After the general gas meter is produced in the factory, the gas company will purchase it and send it to a professional measurement and testing agency formulated by the local technical supervision bureau for testing. The commonly used detection method of professional institutions is to pass the standard gas through the gas meter to see whether the reading of the meter is consistent with the volume of the standard gas.

As a result, the new gas meter will have a reading when the gas is not turned on.

Gas meter installation is useless, why is there a number.

After the general gas meter is produced in the factory, the gas company will purchase it and send it to a professional measurement and testing agency formulated by the local technical supervision bureau for testing. The commonly used detection method of professional institutions is to pass the standard gas through the gas meter to see whether the reading of the meter is consistent with the volume of the standard gas. As a result, the new gas meter will have a reading when the gas is not turned on.

This is the number left when checking the meter, and it is not normal if the gas meter keeps showing the number. Because the gas meter is to measure the amount of gas, if the gas is still rotating when the gas is not in use, then it is likely that there is a gas leak in the gas pipeline, or the gas meter is faulty, and the user needs to close the gas main gate immediately, and then open all the doors and windows, and then notify the relevant departments to come to check and deal with it, try not to do it yourself.

The gas alarm is out of gas, and then just dial that button out and ask what the reason is.

Dear, hello, I'm glad to answer for you, the gas alarm is out of gas, and then dial the button out, the reason is as follows, pull out the solenoid valve button, its working principle is that when the gas alarm detects that the concentration of combustible gas exceeds the standard, it will send out an alarm and the solenoid valve cuts off the gas**. The user simply pulls out the solenoid valve to resume ventilation. The red button on the gas meter is a cutout switch, when you don't use gas for a long time, it will automatically turn off, and when you need to use gas, you need to press the button again to use natural gas.

The reasons are as follows: 1. The air pressure is unstable: the gas stove is on, but the flame is too weak, so weak that it is not possible to reach the stove head, so that the air pressure of the gas stove will be very low, and the natural gas stove will not be able to ignite the fire as usual, and the fire will be extinguished.

2. The gas thermocouple is broken: this situation occurs when the flame of the gas stove is normal, the thermocouple is old and broken, or it is damaged, it cannot provide the strength signal to the pulser as usual, and the pulse of the gas stove will automatically close the solenoid valve, and the flameout will be natural. 3. Other situations:

There are many other reasons, such as a clogged feedback loop in the gas stove, and the feedback needle is so attached that the signal cannot reach the pulser.

Summary. There are usually several possible causes:1

Red button mechanical failure. The red button itself or its mechanical transmission mechanism malfunctioned, and the valve could not be properly actuated to close, resulting in the air supply not being disconnected. In this case, the mechanical parts of the red button need to be inspected for repair or replacement.

2.Valve failure. The supply valve could not be cut off, resulting in a continuous airflow.

When the red button is pressed, the gas valve inside the gas meter should cut off the gas channel and close the gas supply. If the valve is stuck or damaged and cannot be severed, this failure will occur. The valve needs to be inspected, repaired or replaced.

3.Obstruction of the air pathway. The gas line or nozzle at the outlet of the gas meter is blocked, obstructing normal airflow, causing a small amount of gas to flow out even after the red button is pressed.

Blockages in gas lines or nozzles need to be cleared. 4.Tempering phenomenon.

After pressing the red button to cut off the gas source, the residual combustible gas in the combustion system is ignited, and the phenomenon of backfire occurs, and there is still a flame or a small amount of gas flowing out of the outlet of the gas meter. Measures need to be taken to eliminate the flashback and then turn the gas supply system back on. 5.

Solenoid valve failure. Some gas meters use solenoid valves to control the gas supply, and if the solenoid valve fails and the gas cannot be cut off, this failure will occur. The solenoid valve needs to be serviced or replaced.

There are usually several possible causes:1Red button mechanical failure.

The red button itself or its mechanical transmission mechanism malfunctioned, and the valve could not be properly actuated to close, resulting in the air supply not being disconnected. In this case, it is necessary to inspect the mechanical parts of the red button for repair or replacement of the branch ridge. 2.

Valve failure. The supply valve could not be cut off, resulting in a continuous airflow. When the red button is pressed, the gas valve inside the gas meter should cut off the gas channel and close the gas supply.

If the valve is stuck or damaged and cannot be severed, this failure will occur. The valve needs to be inspected, repaired or replaced. 3.

Obstruction of the air pathway. The gas line or nozzle at the outlet of the gas meter is blocked, obstructing normal airflow, causing a small amount of gas to flow out even after the red button is pressed. It is necessary to remove the impermeability plug from the gas line or nozzle.

4.Tempering phenomenon. After pressing the red button to cut off the gas source, the residual combustible gas in the combustion system is ignited, and the phenomenon of backfire occurs, and there is still a flame or a small amount of gas flowing out of the outlet of the gas meter.

Measures need to be taken to eliminate the flashback and then turn the gas supply system back on. 5.Solenoid valve failure.

Some gas meters use a solenoid valve to control the gas supply, and if the solenoid valve fails, it cannot cut off the gas and gas, which will lead to this failure. The solenoid valve needs to be serviced or replaced.

You've done a great job! Can you elaborate on that?

In summary, the red noisy button of the gas meter is invalid after being pressed, which is usually caused by the failure of the red button mechanical parts, gas valves, gas pipelines or solenoid valves. After it is necessary to overhaul or replace the damaged parts of the corresponding jujube, pressing the red liquor pin color button should be able to cut off the gas normally. If the problem persists, the gas company's technician should be asked to inspect and repair it.
