How to open the self-closing valve after stopping gas
Author:
After the self-closing valve is closed, do these steps to open it if it is safe:
First, open the valve in front of the stove to ensure that the gas pipeline is unblocked and eliminate any blockage.
Then, close the valve in front of the stove and pull up the lifting knob of the self-closing valve. If you hear a click, it indicates that the self-closing valve is open and under pressure. At this time, the gas may flow from the pipeline to the gas cooker.
Next, turn on the gas cooker switch that needs to be used, and perform ignition operation. According to the operating instructions of the stove, the ignition is started. Make sure there is a bright flame and normal combustion.
When it is no longer necessary to use the gas cooker, turn off the gas cooker switch, close the valve in front of the cooker, and push the self-closing valve knob downward.
During the above operation, please pay attention to the following safety precautions:
1. Before operation, please make sure that there is no leakage in the gas pipeline. Use foam cleaner or other methods to detect gas leaks. If a leak is found, the valve should be closed immediately and the gas company or professional personnel should be contacted for maintenance.
2. When opening the self-closing valve, the force should be moderate and not excessive to prevent damage to the self-closing valve. Be sure to maintain the normal working condition of the self-closing valve.
3. When using the gas stove, do not leave the stove to prevent gas leakage or accidents. When using, should maintain good ventilation around, to ensure that the indoor air quality is normal.
4. During the shutdown period, all gas appliances should be closed to avoid gas leakage accidents. During the gas shutdown, the gas system can be overhauled and maintained to ensure safe and normal use.
In short, it is essential to ensure the safety and reliability of gas use. When opening the self-closing valve and using the gas stove, the operating procedures and safety regulations should be strictly observed. If you have any questions or operational difficulties, it is recommended to consult a professional or contact the gas company to ensure correct, safe and reliable operation. Let us always be vigilant about the use of gas and pay attention to the knowledge of gas safety to ensure the safety and comfort of the family.
