How do natural gas valves open and close?

1. The natural gas valve is open for "smooth" pipeline, and "horizontal" is closed. The following is a diagram of the opening valve.

2. Attached: The functions of the main natural gas facilities are:

Valve well: A device that controls the valves of underground gas pipelines is installed.

Building regulator box or regional regulator station: A device that adjusts medium-pressure natural gas to a pressure suitable for the user's requirements.

Riser master valve: Generally set on the riser in the kitchen on the first floor of the building, which is used to control all users of the riser.

Indoor main valve: also known as the valve in front of the meter, is the main switch of the gas source of the household, which is placed in the gas meter.

Before, it is used for the on-off of natural gas. This valve is "smooth" for the pipeline to open, and "horizontal" is to close.

Gas meter: IC card smart gas meter, user gas consumption metering device.

Ball valve in front of the stove: the control valve located behind the table and in front of the gas stove, which should be closed after each gas use.

Some homes may be using manual valves. A direct pull of the main valve is sufficient.

If it's an automatic valve, you need to find the battery compartment. 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.

Generally, the ball valve stem is closed perpendicular to the pipeline, and open when it is parallel to the pipeline.

If the stem is stuck in the wall**, try needle-nose pliers.

If the valve is an anti-theft valve, you can only find a gas company to open it with a special tool.

Hello, if you have a handle-style valve, rotate the valve handle to 90 degrees in the counterclockwise direction, parallel to the pipe, it means that the gas has been turned on.

If it is a spherical valve, you can look at the arrow sign above, and as long as you follow the opening sign above, you can open the closed gas main valve.

Hope it helps.

Rotate the handle of the valve of the gas pipeline 90° counterclockwise, and the handle is parallel to the pipe, indicating that the gas is turned on. Some natural gas valves are spherical, usually there will be standard arrows and on/off marks on the valve, and the natural gas valve can be opened according to the prompts on the valve. If the gas meter.

The safety valve closes and the gas meter is placed.

The red button on the top lifts up and you can use it. <

If the gas meter safety valve is closed, lift the red button above the gas meter up to use.

<> natural gas wrench valve is open vertically upwards and closed horizontally. Ball valve, only fully open and closed, homeopathic is open, reverse is closed, as long as the homeopathic twist 90 degrees. The valve is the switch that controls the gas output in the pipeline to the user's home, so it should be noted when using it, and when the valve cannot be opened, the direction of the valve should be determined first.

There is a red plastic button at the upper end of the gas meter, which is the active and urgent closing valve, if the gas consumption exceeds the certain value, it will be actively closed on the grounds of air leakage, open the transparent plastic cover above the button, and pull the red button up to open.

Summary. Hello dear, if the gas valve is closed, you can restart it by manually adjusting the valve. Usually, you can simply open the valve and use a wrench or a handwheel to screw the natural gas pipe back into its normal position.

Hello dear, if the gas valve guess door is closed, you can manually adjust the stove and the whole valve to restart it. Usually, you can simply open the valve and use a wrench or a handwheel to screw the natural gas pipe back into its normal position.

There are also the following ways: 1. Check whether the air valve is loose, if so, adjust it to the correct position with a wrench; 2. Check whether the air valve is dirty, and if so, clean it with detergent; 3. Check whether there is water accumulation in the air valve, and if there is, use a vacuum cleaner to pump out the water; 4. Check whether the valve is damaged, and replace it with a new valve; 5. Check whether there is any air leakage in the air valve, and if there is, seal the loophole with tape; 6. Check whether the valve is damaged and cracked, and replace it with a new valve; 7. Check whether the air valve is blocked, and if so, clean it with detergent; 8. Check whether the valve is damaged, and replace it with a new one; 9. Check whether the valve is loose, if so, adjust it to the correct position with a wrench; 10. Check whether the valve is damaged, and replace it with a new valve; 11. Check whether the valve is damaged, and replace it with a new valve; 12. Open the air valve and check whether the air valve can be opened normally.

The natural gas valve is closed and opened method: 1. How to open the natural gas meter display valve should first find out the reasons that cause the natural gas meter to show the valve closed, and then take the appropriate opening method according to the actual situation, the reasons are different, and the opening method will be different, as follows: 1. If the natural gas meter shows that the valve is closed because of the insufficient power of the battery, the battery should be replaced with a new one, and then the valve switch can be unscrewed in the counterclockwise direction.

If the problem cannot be solved after the battery is replaced, you need to ask a professional to help repair it. 2. If the natural gas meter shows that the valve is closed because of the insufficient natural gas pressure, you should contact the natural gas company and ask the other party to arrange professionals to help solve the problem, because the natural gas pressure is controlled by them, and the pipeline maintenance work is also responsible for them. Tips:

The valve of the natural gas meter must be kept closed and cannot be easily opened, otherwise it is easy to cause safety hazards.

Summary. Dear, hello, I have inquired for you how to open the natural gas valve when it is closed The specific method is as follows:1.

Long-term gas use: If the valve is closed due to long-term gas use, take out the battery in the gas meter, wait for about 10 minutes before replacing the battery, and the gas meter automatic valve can be opened. 2.

Low gas battery: The valve closes due to low power. After replacing the gas meter battery, the valve can be opened.

3.Insufficient gas meter balance: Insufficient gas meter balance causes the gas valve to close.

You can buy natural gas by recharging offline, and then insert the gas card into the gas meter card slot, and the gas meter valve can be opened.

The correct way to close the main valve of natural gas must be to turn off the fire first and then turn off the gas.

1. When the gas trembling stove is used, the strength of the flame can be adjusted by the button, but there is a valve in the gas pipeline to control the natural gas.

2. If the valve is turned off before the fire is turned off, the flame will drill into the pipeline, which will lead to a safety accident, so don't feel that you are wasting natural gas and carry out non-standard operations.

Precautions for the safe use of natural gas:

1. Install gas leakage alarms as much as possible, after all, natural gas is colorless and odorless, unlike coal gas, as long as there is a leak in natural gas, it is difficult for us to detect.

2. Do not install natural gas devices in the bedroom, and maintain ventilation in the space where gas installations are installed. In addition, the gas pipeline should not be kept open to the dark line, which is not easy to maintain.

3. The ventilation effect of doors and windows should be good. Because of good ventilation, once there are harmful gases such as natural gas and carbon monoxide in the room, they can be discharged outdoors in time, thus eliminating the risk of poisoning and poisoning.

4. Regular inspection and maintenance. Regularly inspect whether the natural gas pipeline, natural gas meter, gas stove and hose of the water heater are fixed and whether there are any gas leakage points. If you find a problem, you should find a professional to repair it in time, and don't use it reluctantly. <>
