Natural gas self-closing valve can not be man-made operation
At home, you might come across a safety device called a self-closing valve. This valve is designed to automatically shut off the gas supply in case of an emergency or abnormal conditions, such as overpressure or gas leakage. However, many people mistakenly believe that they should manually turn off the self-closing valve after using the stove. That’s not correct.
For example, Ms. Luo from a local neighborhood mentioned that she used to close the valve every day, thinking it was necessary. In reality, the self-closing valve is an automatic safety mechanism and shouldn’t be manually operated. Under normal conditions, the valve remains in the "green line" position. If the red indicator on the reset button pops out, it means the pressure in the pipeline is too high, and the valve has automatically closed. Similarly, if the lever is fully retracted, it indicates that the gas pipe is disconnected or the hose is removed, and the valve has shut off accordingly.
Another common mistake is leaving the stove valve open after cooking. Mr. Liu from Taoyuan Road shared that his family would often forget to turn off the valve before the stove. This can be dangerous, as the valve before the stove (the red copper knob) should be turned off horizontally after use. Failing to do so could lead to gas leaks, which pose serious risks.
To ensure the self-closing valve is working properly, users can perform a simple self-test. The process involves turning off the gas at the stove before the valve, then checking if the valve automatically closes and the flame goes out. After that, reopen the stove valve, light the stove, and if it doesn’t ignite, it means the self-closing valve is functioning correctly. If any issues are detected, users should contact the gas company’s service hotline at 96777 for professional assistance and maintenance.
By understanding how the self-closing valve works and avoiding common mistakes, users can significantly enhance their safety when using natural gas at home.
