Should I turn off the gas valve after every meal?

The main air valve can neither remain open nor close frequently.

Every time after cooking, many people will choose to close the small valve of the gas stove instead of deliberately closing the main valve of the gas stove, thinking that there will be no danger of gas leakage if the small valve is closed. It is estimated that most of my friends do the same thing. When cooking, everyone thinks it is enough to turn off the small valve. In fact, this practice is wrong. The main gas valve at home can't be closed all the time, and it can't be closed often.

Of course, this question is impossible. If the main valve of the gas stove is not closed, there will be a certain risk of gas leakage. If the main valve of the gas stove is not closed properly, after cooking, although the small valve of the gas stove is closed, there will still be some gas in the pipeline, and there will still be the danger of air leakage or even explosion.

Although the risk of air leakage can be fundamentally cut off after the main valve of the gas stove is closed, if it is closed frequently, the position of the main valve will loosen and damage the valve, and there will be certain safety hazards after a long time.

Correct operation of gas valve in natural gas range;

Usually, in the process of using the gas stove, you only need to close the small valve of the gas stove, but if you don't use the gas stove for a few days or are going out, you must close the main valve of the gas stove in time.

If you want to use the gas stove at home for three meals a day, you only need to turn off the small valve of the gas stove after cooking. If the main valve should be closed after each use, repeated switching will cause certain wear and tear to the main valve.
