Do you have to close the valve every time you run out of natural gas?

It is best to close the valve of natural gas after each use. Because the hose is generally used when the natural gas in the kitchen is connected, the hose itself is relatively short in terms of service life, if the natural gas valve is not turned off frequently, it will cause the corrosion and aging of the hose, so that the phenomenon of air leakage may occur after a long time. Once there is a gas leak, it may cause poisoning, and it may even cause ** phenomenon.

If you encounter natural gas at home**, you can use fire extinguishers, dry powder fire extinguishing agents, wet quilts, etc. to extinguish the flames quickly at the root. Here's how:

Extinguish the fire quickly. Use fire extinguishers, dry powder fire extinguishing agents, wet quilts, etc. to extinguish the roots of the flame quickly; After the fire is completely extinguished, close the valve, remember not to close the valve before the fire is extinguished, and directly closing the valve when the fire is ignited may lead to backflow and cause **; If the fire cannot be controlled, you should quickly leave the scene after evacuating people, call the fire alarm 119** in a place where there is no gas leakage, and immediately report to the customer service center of the gas company; People should be evacuated immediately. Evacuate family members and neighbors quickly, and prevent unrelated people from approaching; Remember not to turn on the lights in the room when the gas leak is on fire.

Don't rub the metal and don't pull the switch off at this time.

Want. Natural gas must be turned off when it runs out, one of which can save gas waste, after all, there will be a little leakage of pipeline gas. Second, it will be safer and avoid a large amount of natural gas leakage and fire.

The second type of netizens feel that cooking and bathing at home every day, it is too troublesome to turn the natural gas valve on and off every time, and it will be too troublesome if you forget to open the valve and run to take a bath one day.

The valve does not need to be closed when the gas is not in use.

The first is that turning off every day can easily lead to damage to the switch, and the gains outweigh the losses. After all, the natural gas valve is also a kind of sealing device, and frequent opening and closing will reduce its service life, and the sealing device will also have gaps, and finally cause natural gas leakage events that cannot be closed tightly.

The second is that today's natural gas is equipped with a safety alarm system, although the valve is not closed, the gas alarm system can also work very well, as long as there is a leak, the alarm will automatically close the main valve, from the root cause of the natural gas leakage problem.

It needs to be closed in the following cases:

1. Business trip or long-term residence in other places:

Such people make very little use of natural gas, so it is best to turn it off after every use. After all, you are not sure if you are at home on the second day, and it is very dangerous for people to have a gas leak when they are not at home, and it is related to the safety of the entire building.

2. People who don't use natural gas regularly:

Today's young people mostly order takeout, so the kitchen is just an ornament for them, cooking is only an occasional pastime, and it is recommended that they turn off the valve after using natural gas.

From a professional point of view, after the natural gas is used up, it is necessary to close the valve in time.

Under normal circumstances, the natural gas is divided into two valves, one is the main valve of the household, which controls the natural gas switch of the whole house, and the other is a sub-valve, which is installed in the air inlet of the water heater, the gas stove inlet and other places, and controls the same gas appliance separately.

Want. If the main gas valve is not closed for a long time, the hose connected to the stove is prone to aging and damage, and the serious circumstances will also lead to gas leakage and gas**; If possible, it is advisable to install a gas alarm, and in case of danger, you can take timely protective measures to avoid more serious damage.

How to maintain gas pipelines: gas pipelines should be checked frequently: check gas pipelines frequently to prevent pipelines from aging, rupture, damage and other phenomena, once problems are found, they need to be dealt with in a timely manner, and take measures to prevent gas leakage.

However, it is best not to use the gas hose for more than 18 months.

Gas pipelines should be regularly checked for gas leakage: regularly check whether the pipeline is leaking, you can use soapy water to check the joints, switches, hoses and other parts of the gas equipment, if there are bubbles, it means that there is a gas leak, you need to open the window immediately for ventilation, it is strictly forbidden to switch on and off electrical appliances and open flames, and at the same time, you should also close the gas main valve, and find a gas company to solve it as soon as possible.

Do not put flammable and explosive materials next to gas pipelines: In order to ensure safety, do not place flammable and explosive materials next to gas pipelines, and try to avoid open flames touching gas sources and gas pipelines, and it is necessary to open windows for ventilation.

Do not move the gas pipeline casually: Do not move, disassemble, modify or bury the gas pipeline without permission because of the impact on the aesthetics, so you must carefully read the safety book issued by the gas company before use, operate according to the instructions, and close the gas main valve after use.

The gas stove is one of the most frequently used appliances in many families every day, and cooking with it is becoming easier and easier, but it still uses an open flame, and the safety issue must not be ignored. In recent years, there have been many kitchen accidents due to improper use of gas stoves, so people are very concerned about this problem: do we need to close the main valve after using natural gas every day?

Personally, I think it is still necessary to close the main valve every day. If the valve is not closed after using up the natural gas, the leather hose connected between the valve and the gas appliance will be easily corroded, and it is easy to crack, become brittle, stiff, and age, which will cause the risk of gas leakage. So closing the valve is a bit more troublesome, but it can provide a guarantee of safety.

Under what circumstances does the gas main valve have to be closed? Let's find out together.

1. At home for a long time. If you need to go on a business trip or if there is no one at home for a few days, then you should close the main valve, so that it is safe for the house, and you need to go to the kitchen to look around before going out.

2. There are rats in the house, generally speaking, there will be rats in very few families, rats may gnaw everywhere in the kitchen, if they bite the gas pipeline, it will be very dangerous, so when mice are found in the house or traces of rats are found, the main valve should be closed, and remember to check the pipeline before each use.

3. When a gas leak occurs, the alarm sound at home prompts the gas leakage, but the reason is not found, don't wait any longer, immediately close the gas main valve, and quickly open the window to let in the air, most of the general gas leakage can close the gas main valve and stop the gas leakage, if the gas main valve is still not working, in addition to ventilation, do not use household appliances, take the mobile phone out of a farther place as soon as possible to contact professionals, you can also contact the community property, to see if the floor valve can be closed.

There are many benefits to closing the gas main valve, and for the safety of life, the main valve must be closed when the gas is used up. This is a matter related to the safety of our lives, so we must pay attention to it.

It needs to be closed, because in this way it can prevent air leakage and protect the safety of people, so it is necessary to close the main valve.

The main valve should be closed, if the main valve is not closed, there are likely to be some safety hazards, so it is the safest after closing.

Yes. Because this can make our lives safer, and to a certain extent, it can also avoid some safety hazards.

Of course, there is no need, if the main valve is opened and closed frequently, it is likely to cause the valve to loosen, so we usually do not often move the main valve when we use it.

In order to prevent the occurrence of potential safety hazards, the valve of natural gas at home needs to be closed every time it runs out.

Natural gas valve is a new type of safety supporting device for gas pipeline engineering. It is used to cut, turn on and adjust the gas in the pipeline, and has good control characteristics and closing sealing performance. It is suitable for city gas, liquefied petroleum gas, natural gas, oxygen and other gas medium pipelines.

With its unique design, novel structure and good sealing performance, the natural gas valve completely solves the problems caused by gas coking and the problems of loose closing and opening of the valve, effectively improves the sealing performance and service life, and truly achieves zero leakage.

The main components of domestic natural gas:

Alkanes, of which methane is the vast majority.

Natural gas is one of the safer gases, it does not contain carbon monoxide, and it is lighter than air, once it leaks, it will immediately spread upward, and it is not easy to accumulate to form ** gas, and the safety is relatively higher than that of other combustion gases.

The use of natural gas as an energy source can reduce the amount of coal and oil, thus greatly improving the environmental pollution problem; As a clean energy source, natural gas can reduce sulfur dioxide and dust emissions by nearly 100%, carbon dioxide emissions by 60% and nitrogen oxide emissions by 50%, and help reduce the formation of acid rain, alleviate the global warming effect, and fundamentally improve environmental quality.

Should I close the valve after running out of domestic natural gas? Everyone has always thought wrong, and learned to use it for a lifetime.

In fact, on this issue, everyone has their own practices and ideas, when using gas, everyone is most worried about the problem of gas leakage, some people feel that there is no need to close the valve after the gas is used up, because every time it is closed, it will be very troublesome, and if the frequent switch may lead to the stability of the valve, it may increase the risk of gas leakage.

However, some people believe that the valve after using the gas stove needs to be closed, but it is not a frequent switch but closed at night, and many people choose to do this, because it can prevent accidental air leakage at home when sleeping at night.

The above two statements seem to be very reasonable, so should it be closed or not? The gas master said that if the valve is not closed for a long time, the hose connecting the stove is very easy to age, and now whether it is day or night, because the weather is very cold, if the gas really leaks, the risk is very large. So even if we don't want to turn it off during the day, we must turn it off when we go to bed at night!

In our real life, many people are troublesome not to turn off the gas valve, but it is actually unsafe to do so, it is recommended that you still pay attention to the safety of gas, after all, if something like this has an accident, it is really very serious! Therefore, the gas master also warned us that if the gas at home is a hose, then we must pay attention to whether the hose is soft and damaged.
