Is it better to close the main gate or turn off the stove first when using natural gas?

1. When using natural gas, turn off the stove first and then close the main gate.

2. Close the main gate after turning off the stove, so that there is still some gas in the pipeline, but because it does not circulate, it will still stay in the pipeline, so that it will be easy to ignite when you use it again There is very little gas in the pipeline, even if it leaks, there is no harm.

3. Turn off the stove first, because the fire is not extinguished, and the residual gas in the pipeline will be burned out. In the next use, the non-flammable gas in the pipe must be ejected and ignited. If you don't grasp it well, accidents will happen.

If you do this, I recommend that you turn off the stove first and then close the main gate Because there is still some gas in the pipeline, but because it does not circulate, it will still stay in the pipeline, so that you will easily ignite when you use it again There is very little gas in the pipeline, even if it leaks, there is no harm If you turn off the main gas first and then turn off the stove, because the fire is not extinguished, the residual gas in the pipeline will be burned out The next time you use it, you must push out the non-flammable gas in the pipe and then ignite it If you don't grasp it well, deflagration will occur. When people are afraid, they are prone to fire

It should be closed first and then natural gas.

Reasons:1If the gas is turned off first and then the gas stove is turned off, there will be air in the pipes between the bottle and the gas stove, making it difficult to ignite the next time. It may take a few fires.

2.Generally, the connecting pipe will not leak, and even if it does, it is limited in safety.

3.It's not a big problem to close first, remember that it's key and safe to turn off both.

Summary. It's time to turn off the heat first, then the gas.

Whether a liquefied gas tank is used, or natural gas is used, there is a valve that controls the gas output, called the stove front valve. Many users are accustomed to closing the valve in front of the stove after cooking, so that the residual gas in the pipe can also let the stove burn for a while, and then automatically extinguish, which can not only save gas, but also avoid the unused gas volatilization into the air and cause harm to the body.

In fact, it is not right to close the valve in front of the stove first, because the fire on the gas stove has not been extinguished, if the valve in front of the stove is closed first, the fire on the stove is likely to enter the gas pipeline along the stove, which is not only easy to damage the pipeline and valve, but also causes safety accidents such as ** in more serious cases.

Therefore, whether you use gas or natural gas in the future, the correct way is to close the valve on the gas stove (also known as the stove valve) first, and then close the valve on the gas pipeline after the fire is extinguished, that is, turn off the fire first and then turn off the gas.

When turning off natural gas, should I turn off the gas stove or the valve first?

It's right to turn off the heat first and then turn off the gas, there are many people who say that it is right to turn off the gas first and then turn off the fire, and I don't know if it's right when I'm here first.

It is more convenient, safer and more scientific to turn off the gas first.

It is safe to turn off the liquefied gas cylinders and then wait for the fire on the stove to go out automatically before turning it off.

Because there will be a section of hose connection between the liquefied gas stove and the liquefied gas tank, if the stove switch is turned off first, there will be some liquefied gas left in the hose, once a leak occurs, the liquefied gas will be dispersed into the air, which is very dangerous, and if it encounters an open flame, the consequences are even more unimaginable.

After use, the possible results and safety factors of different operation methods are different.

If you turn off the cooktop switch first, that is, turn off the heat first, the cylinder is still connected to the hose, and the pressure inside the hose is the same as the pressure in the cylinder. If we forget to close the bottle valve in the end, the strong pressure of filling liquefied gas also brings a strong "pressure" to the hose, and it is not 100% guaranteed that there is no leakage at the hose connection, as long as there is leakage, the amount of the entire liquefied gas tank will be missed.

If the bottle valve is closed first, that is, the gas is turned off first, the connection between the cylinder and the hose is cut off immediately, the pressure in the hose is reduced, the nozzle of the stove is sprayed out without liquefied air, the fire is extinguished, and a small amount of liquefied gas remains in the hose, and there is no danger of liquefied gas leakage, and the safety factor of this operation is high.

The correct order for natural gas stoves is to turn off the heat first and then turn off the gas. There are a total of 3 steps, and the following is the detailed operation of the correct order of the gas stove:

Steps.

Turn the gas switch on first.

Turn on the gas switch before using the gas cooktop.

Turn on the gas cooktop.

After that, turn on the switch of the gas cooker and turn it on for use.

Turn off the gas stove first.

After not using the stove, be sure to turn off the gas stove first, and do not turn off the gas switch first. After that, turn off the switch of the gas pipeline.

When turning off the natural gas, you must turn off the gas stove first, and then close the valve, and the order is best not to make a mistake, so as not to cause danger and cause danger.

When turning off the natural gas, you should turn off the gas stove first and then close the valve, which can avoid the danger that may occur when you turn on the gas stove next time.

The gas stove should be turned off first, and then the valve should be closed, so that the order will not cause some harm to the gas stove.

After using natural gas, close the valve first and then turn off the gas stove. Because after each use of the gas stove, there will be a small amount of gas left in the gas pipe, if the switch of the gas stove is turned off first, the residual gas in the pipe will not be fully burned, and will volatilize, which is very bad for people's health. Therefore, after the natural gas, close the valve first and then turn off the gas stove, and the natural gas in the pipeline in the gas stove will be fully burned until it is extinguished, and then turn off the switch after the fire is extinguished.

It is environmentally friendly and avoids the danger of natural gas leakage.

Precautions for the use of natural gas:

1. Other fuels (such as bottled liquefied gas, coal, oil, etc.), residents and sundries shall not be used in the places where natural gas facilities are installed.

2. It is strictly forbidden to dismantle, modify or install gas facilities without permission.

3. It is strictly forbidden to push and release sundries around the gas pressure regulating box (cabinet and station), and the road should be kept unimpeded.

4. In order to ensure the safety of gas users, in addition to the regular safety inspections conducted by gas companies, gas users should frequently conduct daily leak detection. The common method is to use a brush dipped in soapy water to apply to the joints of the gas pipe, if there are bubbles, it means that there is a gas leak. It is strictly forbidden to inspect with an open flame.

When turning off the fire of a household gas stove, should the stove be turned off first, or should the gas valve be turned off first?

Some people say that the gas valve should be turned off first, and then the stove should be turned off after the gas in the pipe is burned and extinguished, so as to prevent gas leakage accidents due to forgetting to close the gas valve. Some people say that the stove should be turned off first, and if the gas valve is closed first, there is still pressure in the gas stove pipe, and the fire of the gas stove is still burning, which is easy to cause the hose to backfire, which will cause a fire.

Although I have not heard of a fire caused by a different sequence of turning off the fire, I prefer to turn off the stove first and close the air valve. First of all, the gas stove now has flame-out protection, if the gas valve is closed first, it will cause active flame-out protection, which will not only cause battery consumption, but also increase the burden of the flame-out device, which is easy to cause problems in the gas stove. Secondly, if the gas valve is closed first, it will cause the fire to burn into the hose, although it will not happen immediately, but it will lead to dangerous situations such as aging and damage to the hose in the long run.

If you turn off the stove first, the next time you light the stove, it will be easy to start a fire because there is a little gas stored in the trachea.

Finally, there are many people who think that the valve is easy to cause damage to the valve, so they only turn off the stove, and only close the valve before going to bed or when they go out far away, and even some people never close the valve. In order to prevent gas leaks, which can lead to tragedy, it is advisable to pay attention to these problems

1. Whether the hose connected to the stove is loose or aging.

2. Whether the stove valve is closed tightly.

3. Whether the pipeline is corroded, whether the valve and interface are loose, etc.

4. The doors and windows of the kitchen should be opened frequently for ventilation.

5. When cleaning and moving the cooktop, be careful to prevent the interface from loosening due to excessive movements.

6. It is best to develop the habit of closing the valve, so as not to lose more than the gains.

Finally, I would like to remind everyone that whether it is a gas valve or a natural gas valve, both of them will have gas leakage, but the problem of the size of the gas leakage flow. In daily life, it is better to develop a good habit of closing the valve casually!

Turning off the gas first and then turning off the gas stove is a big mistake. In fact, the gas valve is closed first, there is no pressure in the gas pipe, and the fire of the gas stove is still burning, which is easy to cause backfire, and the fire is burned back to the gas pipe to cause a fire. Therefore, the most correct and safest way is to use the gas stove, first turn off the gas stove switch, and then close the gas valve.

The gas valve should be closed first, and then the switch should be turned off, so that the gas can be more economical and the service life of the gas stove can be improved.

Turn off the stove first, which is not only very safe, but also not easy to cause disasters, which is very beneficial to people's life safety.

If you use a gas stove at home, should you turn off the stove or the valve first? Don't make a mistake about this order.
