Should the natural gas valve be closed every day, and what should I pay attention to?

For safety reasons, the natural gas valve can be closed every day.

Generally, the natural gas at home will be installed with a valve in front of the meter and a valve in front of the stove, and the valve in front of the stove can be closed in general, and the valve in front of the meter can not be closed at will. And it is best to check the valve in two or three months to avoid damage to the valve and deal with it in time to avoid more serious accidents.

It does not need to be closed every day, and Meituan is not easy to cause valve aging, and most of the current natural gas valves have roommate alarm systems, which can work well even if they are not closed. However, when you go out or do not use natural gas for a long time, you need to turn off the natural gas, and regularly take care of the natural gas pipeline to avoid damage to the pipeline due to aging.

Closures are required on a daily basis. Be sure not to let children turn it off, be sure to close it tightly when closing, be sure not to take an open flame when approaching natural gas, and do not turn on the natural gas switch after closing the natural gas valve.

Personally, I don't feel that I need to, if you go out far away, you can turn it off, if you use it every day, you can check whether there is any gas leakage when you use it, pay attention to the maintenance of the surrounding environment of the gas stove, don't put some flammable things, and turn it off in time when you don't use it.

There is no need to close it every day, if you leave it for a long time, you must close it, and you can close the valve when you use it every day, and you don't need to close the main valve.

If there are people in the house, there is no need to close the valve every day, because it will make the valve very loose, and the valve should be closed if there is no one in the house.

Introduction: With the development of society, whether it is urban or rural, many families have access to the most cheap and safer natural gas. But for the use of natural gas, I believe many people have a question, does the valve of natural gas need to be closed every day?

Next, I will write about my own experience, hoping to give you some help in this regard.

1. Does the natural gas valve need to be closed every day?

There are generally two valves for natural gas, one is close to the gas stove, which is called the front valve; The other is close to the gas meter, which is called the front meter valve. In the early days of the natural gas industry, the stove valve would close every time it was used up. Nowadays, many gas companies have replaced the front valves and hoses with airflow protection devices when installing stove front valves and hoses, and the hoses have also been replaced with metal hoses.

So if you have a valve with a guard, there is no need to turn it off when you use the gas every day. If you don't worry, you can also close it every day, the current gas stove switch valve is of good quality, and there is no problem with switching more than 30,000 times. In addition, it should be noted that if you are going to go far away, close the valve in front of the stove in addition to the valve in front of the table.

2. Precautions for the use of natural gas.

Although natural gas is safe to use, there are a few things we need to pay attention to during the use of natural gas to prevent accidents. Do not turn off the gas alarm system, if there is a gas leak in the home without an alarm, the consequences are very serious, and safety is more important. When using natural gas, you can leave a little gap in the window.

In addition, when buying gas pipelines, you must not be greedy for cheap, and buy some products that do not have a certificate of qualification and are not of good quality.

3. The difference between natural gas and liquefied gas.

Liquefied gas is mainly used as a petrochemical feedstock and can be used as a fuel for industrial, civil and internal combustion engines. Natural gas is a relatively clean source of energy, not only as a fuel, but also as a food freezer, air liquefaction and power generation.

The natural gas valve must be closed every day, because if the gas is not closed, it is easy to cause gas leakage, and the consequences of leakage are unimaginable. In addition, if the gas valve is not closed, the hose will deteriorate and the pipe body will become brittle after a long time, which will have great safety risks.

There are generally two valves after natural gas enters the house, one is called the valve in front of the meter, the valve in front of the meter is basically not closed, the valve in front of the stove will be closed after the gas is used up at the earliest, and now many gas companies have installed the valve and hose in front of the stove, which has been replaced with a valve with an overcurrent protection device, and the hose is replaced with a metal hose, so if you are a valve with protection, there is no need to close it when you use gas every day, and the switch valve of the gas stove is now of very reliable quality, and there is no problem with switching more than 30,000 times. As a result, there are no leaks during the normal service life of the gas stove. Therefore, there is no need to switch off the pre-stove valve.

Household gas valves include public pipeline valves, household main valves (front of the meter valve), gas stove valves (front of the stove valve), and different valves are treated differently. Public plumbing valves have little to do with our family. It is forbidden to switch on and off arbitrarily, and it is strictly forbidden to close without accidents.

It is strictly forbidden to open it at will after the closure in the event of an accident. The household main valve (front of the meter valve) does not need to be closed every day, and is only closed when the natural gas is not used for a long time, or the gas equipment is faulty and needs to be repaired or replaced. First of all, the installation position of the gas meter is generally closed during the decoration.

The common ones are installed in the cabinet, and there is a certain position from the ground, which is not very convenient to operate. So it's not usually to operate the valve. Secondly, because the valves in front of the gas meter are all connected through galvanized pipes and then using wire joints.

Therefore, this part of the pipeline will not appear to be aging and leakage, and this valve is only used as a general maintenance valve, not as a usual operation valve.

The gas stove valve, also known as the stove front valve, is the control valve between the gas pipeline and the stove. Every time you finish cooking, in addition to turning off the switch on the gas stove, you also need to close the valve in front of the stove. Because the rear of the valve in front of the gas stove is connected to the gas hose, which is generally connected by a clamp, many people do not replace the hose for many years, and the hidden danger is very large, and this hose generally needs to be changed once every two years; Or use bellows to connect with fittings, which can also lead to air leakage over time.

And once the gas stove at home is used for a long time, there will be hidden dangers of gas leakage, and in the process of not using it, try to close the valve as much as possible, so that it is the safest. Special attention should be paid to the safety aspect when closing the valve. First of all, the gas company's home inspection, if the gas pipe is found to be aging and the valve is loose during the inspection, it must be replaced in time to avoid accidents.

Secondly, you must pay attention to the gas situation at home at ordinary times, and check the gas stove in the kitchen every day before going to bed and going out, and whether you have forgotten to turn it off. If you are out for more than two days, turn off the gas main valve. If you find any peculiar smell, be sure to close the valve in time and report for repair.

In addition, in winter, in order to warm the room and close the doors and windows, in case the valve is loose, or the gas pipe leaks, there is a great safety hazard, so the kitchen window should also be always open to keep the kitchen and indoor ventilation, even if there is a slight leakage of gas, it will not cause deflagration.

It needs to be closed every day, and if it is not closed, there is a high risk of danger, so close the valve.

It should be closed every day, because it is safer to close the valve and avoid dangers and accidents.

If you cook every day, don't turn it off every day, and if you don't often stay at home, you need to turn off the gas valve every day.

It's a matter of safety, and the clear answer is that you need to shut down every day. Nowadays, basically every household in the urban area is equipped with natural gas, and maintaining a good habit of using natural gas is not only beneficial to oneself, but also responsible for others. One is the front of the table valve, the other is the front of the stove valve, in which the front of the meter valve is basically not turned off, of course, it is best to close it every time it is used.

For users who don't cook, don't use gas for a long time, or go out for a while, they must close the valve in front of the meter.

Theoretically, the valve in front of the stove should be closed; The reality is that the current gas company uniformly installs the front meter valve and the front stove valve, which are all high-quality things, and the number of switches is too many but leaksNatural gas switches are susceptible to aging and wear. The switch is actually a kind of sealing device, if this device is often closed, there will be friction between the sealing devices, the more friction, the gap between the devices will be larger and larger, at first I don't understand, for the principle of safety first I are to close the two valves, that is, the valve in front of the meter and the valve in front of the stove are closed.

In the process of daily use of natural gas, it is necessary to pay attention to maintenance and observe the smell at all times. Natural gas, whether it is a pipeline or an interface, with the increase in the frequency of daily use, it is inevitable that it will loosen, so it is necessary to carry out regular maintenance, but use natural gas to make the home cleaner. However, in recent years, natural gas safety accidents at home have also occurred frequently, especially the fire caused by natural gas leakage at home is really common.

Because the safety valve often rubs, there will be a gap at the interface of the screw, so that it will invisibly leak air, and it will cause ** after encountering an open flame. The valve at the connection between the gas meter and the gas stove hose behind the gas meter, this valve is smaller, generally a knob type, and is used to close the gas pipeline on a daily basis. The valve in front of the meter is a mechanical handle, which is generally used for pipeline maintenance, and the valve behind the meter is replaced, so the water heater is often used at night, and after the water heater is used in the morning, it is usually forgotten to close the gas pipeline valve before the water heater.

Don't, if you have to close it every day, it is easy to loosen the valve and cause leakage, so it is best not to move the valve too often.

Don't, it is easy to damage the valve of the switch when it is often switched, and there is a certain inconvenience when using it, and it is easy to cause accidents.

I don't think it's necessary. Because the design of natural gas is very rigorous, it will be cumbersome to shut it down every day.

Yes, as this is a safe operation and can prevent gas leakage.

Nowadays, many people will use natural gas at home, and we must also pay attention to safety at this time, if you have opened the valve of natural gas, we must close it immediately at this time. We all want to be very safe, so there are a lot of issues that everyone needs to pay attention to, and we must also be prepared for it in life, so that you will become a little more relaxed.

Is it necessary for us to close the valve on natural gas?

In fact, each of us will have our own ideas, but we also hope that our personal safety can be guaranteed to a certain extent, and we also hope that we are very safe, so we should improve our safety awareness at this time. We must also pay attention to related problems in our daily lives, and we must also ensure our own safety at this time, so it is recommended that you close the valve, although many people will find it particularly troublesome, but this is also a step that we can not omit, otherwise your life may be threatened.

What should we do?

Now many people will use natural gas, and everyone also knows that natural gas meters are cheap, so we can use natural gas to cook, but we need to pay attention to a lot of problems, if you have opened the valve of natural gas, we must remember to close the valve of natural gas at this time. Especially if you are going out, we must choose to close at this time, otherwise it is easy to have a lot of problems, so these problems are also necessary to attract everyone's attention.

In conclusion, these issues need to be taken seriously, but there is no need for us to worry too much. Each of us has different choices, and many people will not use natural gas, but we must also improve our safety awareness at this time. Therefore, we must choose to close the door when we go out, so that it will be safer.

Natural gas valves are meant to be closed every day, especially when you go out, because natural gas valves are very dangerous. When closing the natural gas valve, you should also observe whether there is a problem with the natural gas.

There is no need to turn it off every day, because this is not only very troublesome, but also can easily cause the interface of the switch to slacken, which will lead to air leakage.

No, you don't. If the natural gas valve is closed every day, it is likely that the valve will malfunction, and there is a high risk of natural gas leakage.

There are three types of natural gas valves, namely gas stove valves, front valves, and rear valves. The gas stove must be turned off every day, and it must be turned off after cooking, otherwise it is easy to cause gas leakage. In addition to the trouble, many households do not close the valve when they run out of natural gas.

They are always worried that repeated shut-offs every day will damage the valve and shorten its lifespan. Actually, there is no need to think so. Generally speaking, there are generally two valves after natural gas enters the home, one is called the valve in front of the meter and the other is called the valve in front of the stove.

The front valve is basically not closed, and the front valve of the furnace will be closed when the gas is used up at the earliest. Nowadays, many gas companies have replaced the valves and hoses in front of the furnace with valves with overflow protection devices, and the hoses have been replaced with metal hoses.

So, if you have a valve with protection, there is no need to turn it off when you use the gas every day.

The on-off valve of the gas stove is now of reliable quality, and there is no problem in switching it on and off more than 30,000 times. The valve must be closed at all times, not for economy, but for safety. In the future, natural gas users should gradually install gas leakage alarms, replace hoses with metal hoses, and replace valves with valves with overflow protection devices.

The tail valve is the front valve, and the main factor in determining whether the front valve is needed is the hose material. If it is a hose, close the valve in front of the gas stove in time when it is used up. Hoses are prone to deterioration, and if a crack appears, it can cause air leakage.

Therefore, it is not only necessary to close the valve in front of the furnace in time, but also to replace the hose every 18 months.

If it is a stainless steel pipe.

There is no need to close the valve in front of the furnace every day. The metal pipe has the advantages of high temperature resistance and wear resistance, and can be used for up to 8 years. The front valve, which is usually installed in the cabinet in the closed position, is the main valve used to control the use of gas in the room.

It is not very convenient to operate, so there is no need to switch it except in the case of a long period of time when no one lives or there is an accidental gas leak. The front valve is the control valve between the cooktop and the gas pipe. It is recommended to turn off after cooking.

This is because the rear of the valve in front of the furnace is connected to the gas hose, which has been used for a long time and has certain safety hazards.

There may be a risk of air leakage.

Secondly, some homes have a longer lifespan of gas stoves. If you just close the valve on the gas stove, you may not close it. So it's best to turn off the front valve of the stove when not in use, so that it can be safer.

Some people think that turn off the heat first, then turn off the stove. After the gas is used up, there will be some gas left in the gas pipeline, resulting in gas waste. At the same time, the evaporation of gases into the air can pose a threat to our health, so we should turn off the furnace first.

However, if the stove is turned off first, the residual gas in the pipe will continue to burn, and when the gas is about to run out, the gas stove and valve may back-suck because there is no air pressure, that is, the flame burns along the gas pipe, causing a fire. So the correct conclusion is: turn off the heat first, then turn off the stove.

Don't make a mistake because you feel like it's a waste of gas.
