After using gas, should you turn off the gas first or the fire first?

Some people may think

You should turn off the gas first, and then turn off the fire after a while.

Because they feel that after using gas

There is still residual gas in the pipeline

If you turn off the fire first

May waste gas

But this is wrong.

There are potential dangers in doing so

Don't think it's a waste of gas.

Performing wrong operations

The correct approach should be

Turn off the fire first and then turn off the gas!

"Indoor Gas Valve Strategy"

Let’s learn about it together~

01

Gas stove valve

The gas stove valve is the valve we are most familiar with, and we use it when cooking every day.

Gas stove valve

As the switch of the gas stove, its main function is to ignite and cut off the gas source to the gas stove. If it fails during the use of the gas stove, you need to immediately close the plug valve (the valve in front of the stove), stop using the stove, and contact a professional for inspection and repair in time.

We use it frequently, and the valve must be closed after each use!

02

Plug valve (stove front valve)

————

The plug valve is generally designed to be installed near the gas stove (or water heater) to connect the gas pipeline and the hose. As the second safety key of the gas in the home, it is very important, but it may often be overlooked.

After using the gas, some friends turn off the gas stove and go back to the living room, often neglecting to close the stopcock. If the hose is bitten by a mouse in the middle of the night and the valve is not closed, it will cause gas leakage. Therefore, the valve must be closed after each use of gas. If the valve fails, call the local gas service hotline in time to report the problem.

Plug valve open and closed status

We tend to overlook it. For safety reasons, check whether the stopcock is closed every night before going to bed.

03

Main valve

————

The main valve at the entrance of the house (the valve in front of the gas meter, the main gas source switch) is mainly used to control the on and off of the gas in the home and controls the gas supply for the whole family.

If you are going to travel far away or do not need gas for a long time, remember to close the main valve at the entrance (the valve handle is perpendicular to the pipe) to prevent gas leakage. If a gas leak occurs at home, open the doors and windows for ventilation, close the main valve at the entrance, and go to a safe place to call the gas service hotline for emergency repairs.

Open and closed status of the main inlet valve

When using gas in daily life, friends must not operate it without authorization. It is strictly forbidden to use decorations to close the main valve during renovation to avoid difficulties in emergency response.

The main valve entering the house does not need to be closed every time the gas is used up, but it must be closed in time when the gas is not used for a long time or a gas leak occurs.
