What is the switch under the natural gas self closing valve and does it need to be closed every day?

Natural gas valves are usually divided into general valves and sub-valves, the total valve is also called the front valve, usually the front valve does not need us to switch, but professionals need to regularly check whether there is gas leakage or whether there are other safety problems, often the switch will reduce the number of use, resulting in the loosening of the valve, which causes safety problems, so it does not need to be closed every day. It can be closed when going out to prevent hidden dangers; The sub-valve is usually the gas stove valve, also known as the stove front valve, the back of the valve is connected to the natural gas pipe, the natural gas has been in the natural gas pipeline for a long time, the pipeline will be slowly corroded, there are certain safety hazards.

Therefore, it needs to be closed every day.

Abstract Hello dear, of course, it is closed, whether it is used or not, the valve of natural gas needs to be closed in time to avoid safety accidents caused by valve damage, and natural gas also needs regular maintenance to ensure the safety of gas. Consultation Record · on 2021-12-27 Without natural gas, should the safety self-closing valve be open or closed? Hello dear, of course, it is closed, whether it is used or not, the valve of natural gas needs to be closed in time to avoid safety accidents caused by valve damage, and natural gas also needs to be overhauled regularly to ensure the safety of gas.

Does the valve on the gas stove need to be closed every day after cooking Does this small switch need to be turned off every time What is the one next to it called, does it need to be closed, don't need to close it every time, just turn it off before going to bed every night The round one next to it needs to be turned on or off all the time Close the idle pro.

It's still needed.

Manually now installed.

That's what needs to be used.

It is best to turn it off when it is used up every day.

Do not worry. It will be used for a long time.

The ball valve can control the opening of the natural gas, and the gas stove and pipeline are normal without having to close every time they are used.

Hello dear! Glad for your question! Does a natural gas self-closing valve need to be closed? ：

1. Of course, it should be turned off every time; 2. The natural gas valve is the main control switch of household gas, if it is not closed when not in use, once the leather pipe connecting the pipe and the stove falls off or is bitten by mice, it may cause gas leakage, and the consequences are unimaginable. It is easy to leak and is a dangerous gas. In the event of an open flame, accidents are prone to occur in a confined space; 3. Don't be too troublesome, the natural gas valve does not need to be closed, especially when there is no one at home for a long time and in the family of people who have smoking habits.

Leaking gas waste is secondary, safety is important!

Hello dear, happy to answer your questions! Analysis of the reasons for the automatic closing of the natural gas self-closing valve: In the case of gas shutdown or excessive pressure or underpressure in the pipeline network, the natural gas self-closing valve will be automatically closed.

1: Self-closing valve is a device installed on the indoor gas pipeline, in general, the self-closing valve reset button lever is in the green line scale state, when the red line on the reset button lever pops up, the self-closing valve will automatically close because of the excessive pressure of the gas pipeline, often manually closing the self-closing valve will make the self-closing valve fail, thus causing gas leakage, we should close the front valve of the stove after cooking, and then close the stove valve. 2：

Under normal circumstances, the self-closing valve reset button lever of the self-closing valve is in the green line scale state, when the red line on the reset button lever pops up, it means that the pressure of the gas pipeline is too large, and the self-closing valve is automatically closed, and when the reset button lever is all retracted, it means that the pipeline is stopped or the gas hose falls off, and the self-closing valve is automatically closed. 3: Therefore, when there is underpressure, overpressure or loss of pressure in the pipeline air supply, the self-closing valve will be automatically closed.

In addition, in the event of an air outage, abnormal air supply, or hose disconnection, the self-closing valve will automatically close. There is also a possibility that the purchase of inferior self-closing valves makes the use insensitive. 4：

If the gas pipeline self-closing valve is automatically closed, it is recommended that non-professionals do not check and repair without authorization, and must call the gas company and ask someone to come to the door for maintenance.

Cause analysis: the air pressure is too low, causing the valve to close automatically. Workaround:

1. Some families may use manual valves. A direct pull of the main valve is sufficient. 2. If it is an automatic valve, you need to find the battery box.

Put the battery and the battery inside down. Then wait about 10 minutes before putting the battery back on. The valve opens automatically.

Then gas can be used. 3. If this does not solve the problem, you can **call the customer service of gas**. The valve of natural gas is automatically sucked in, in most cases the "gas self-closing valve" is installed, that is, the small gas valve, when the indoor gas is abnormal, including no gas, gas overpressure or low pressure, the gas self-closing valve will be automatically sucked in when it is protected, which is a very safe design.

1.If it's a manual valve. Just pull the main valve directly.

2.If it is an automatic valve, you need to find the battery compartment and remove the battery inside. Then wait ten minutes before putting the battery back on. The valve opens automatically.

The solution for automatic closing of natural gas self-closing valve is as follows:

The solution is divided into two situations: when the gas self-closing valve is shut down, or when the pressure generated is large, it will automatically close, so as to prevent leakage, which is normal and does not need to be operated.

When the reset button lever is in full, the old code stops the gas, or the gas hose falls off, then the self-closing valve will also be automatically closed, and it is necessary to contact professionals to deal with it in time.

Attention should be paid to the use of gas pipeline self-closing valves.

When the ball valve behind the gas pipe self-closing valve behind the stove is closed under normal air pressure, manually pull the handle up and hold it for 3 to 5 seconds. The valve is then released and left open.

When the gas pipeline self-closing valve exceeds the red line, it means that the valve is in a state of overpressure, and the ball valve at the rear end needs to be closed in time, and then contact the gas company for treatment. When the fault is dealt with, the ball valve can be restored to the closed position, and then it can be opened normally.

If the gas pipeline self-closing valve is in the closed position, check whether the hose between the valve and the stove has fallen off or cracked, and if not, check whether the inlet pressure is too low. Only after the fault has been dealt with, can the valve be opened normally.

AbstractIn the case of gas shutdown or excessive pressure or underpressure in the pipeline network, the natural gas self-closing valve will be automatically closed.

The self-closing valve is a device installed on the indoor gas pipeline, in general, the self-closing valve reset button lever is in the green line scale state, when the red line on the reset button lever pops up, the self-closing valve will automatically close because of the excessive pressure of the gas pipeline, often manually closing the self-closing valve will make the self-closing valve fail, thus causing gas leakage, we should close the front of the stove valve after cooking, and then close the stove valve.

What is the reason for the automatic closing of the natural gas self-closing valve.

Hello, I have seen your question and am sorting out the answer, please wait a while

The self-closing valve will automatically close when the pipe network stops gas or the pressure is too large, under normal conditions, the self-closing valve reset button pull rod is in the green line scale state, when the red line on the reset button pull rod pops up, it proves that the pressure in the gas pipeline is too large, the self-closing valve closes by itself, when the reset button pull rod is all retracted, it means that the pipe network is out of gas or the gas hose falls off, and the self-closing valve also closes by itself.

It's okay at noon, so how to solve it.

In the case of gas shutdown or excessive or underpressure in the pipeline network, the natural gas self-closing valve will be automatically closed. The self-closing valve is a device installed on the indoor gas pipeline, in general, the self-closing valve reset button lever is in the green line scale state, when the red line on the reset button lever pops up, the self-closing valve will automatically close because of the excessive pressure of the gas pipeline, often manually closing the self-closing valve will make the self-closing valve fail, thus causing gas leakage, we should close the front of the stove valve after cooking, and then close the stove valve.

How to fix it. Solution: 1. Find the power box of the solenoid valve, take out the battery, and then put the battery back into the battery box after a few minutes, and then the solenoid valve can be used normally. 2. Manual valve treatment method: close the manual valve handle and then open it for normal ventilation.

Every home is different, and so is the gas stove in every home. When it comes to solving the problem, your family may use a manual valve, and we can solve it by directly operating the main gate. If it's an automatic valve, we find the battery box, take all the batteries inside, wait for ten minutes or 20 minutes, and then reinstall the battery, and we will automatically open it to use gas.

If none of the above solutions can solve this problem in your home, then we will call the company of gas ** and ask a professional to help.

I'm sorry, I'm not a maintenance professional, and the guidance provided has already been explained. Please also be smart for specific operations.

Natural gas self-closing valves do not need to be closed every day. Installed on low-pressure gas system pipelines. When the pipeline air supply pressure is underpressure and over-rolling, it can be automatically closed and opened manually, without electricity or other external power.

The self-closing valve installed at the end of the pipe and the hose connection behind the gas meter should have the function of closing the loss of pressure.

Summary. If there is a self-closing vent valve, it can be closed automatically. The valve on the stove should be closed every time you use the gas stove, you can leave the valve behind the gas meter off, but you should always check whether there is any air leakage between the connecting hose and the stove.

Problems are found and dealt with in a timely manner. Suggestions: 1. Always check whether the hose connecting the gas pipeline and gas appliances is flattened, aging, whether the interface is loose, whether it has been bitten by sharp objects or rats, and if the above phenomenon occurs, you should contact the gas company immediately.

2. Replace the hose regularly. According to the relevant gas safety management regulations and technical specifications, the hose should be replaced every two years.

Is the gas belt self-closing valve still closed every day? , Chafu gas belt self-closing valve still needs to be closed every day. This is because the self-closing effect of the self-closing valve only works when the pressure reducing valve is not installed.

The gas used at home has been connected to the reducing valve, so the self-closing valve can no longer play a role, and it will leak if there is a leak. Therefore, it is still necessary to develop the habit of closing the valve every day.

If there is a self-closing vent valve, it can be closed automatically. After each use of the natural gas stove, you should close the valve on the morning utensils of the sleepy burning stove, you can leave the valve behind the gas meter unclosed, but you should always check whether there is any air leakage between the connecting hose and the stove. Problems are found and dealt with in a timely manner.

Suggestions: 1. Always check whether the hose connecting the gas pipeline and gas appliances is flattened, aging, whether the interface is loose, whether it has been bitten by sharp objects or rats, and if the above phenomenon occurs, you should contact the gas company immediately. 2. Replace the hose regularly.

According to the relevant gas safety management regulations and technical specifications for dubo, the hose should be replaced every two years.

Hello, dear The question you consulted, here is the following answer for you: In fact, under normal circumstances, as long as you open the self-closing valve, you don't need to close the main valve, because if the pipeline leaks, overpressure, overflow and other problems, this self-closing valve will automatically close and play a protective role, which is also the purpose of installing it, not only to ensure safety, but also to facilitate our lives, after all, it is very troublesome to close the gas main valve every day, in case you forget it one day, There are also certain risks. Usually open it, you don't need to care, and often open and close the self-closing valve, it is easy to fail for a long time, resulting in guess leakage, the gas stove at home is used every day, so there is no need to close it at all, and usually do not think that the valve is opened and closed at will.
