After installing the gas meter in the user's home. The device at the f end of the gas pipeline is a self-sealing valve.
The gas self-closing valve is composed of an inverted body, a reset button, and a front valve. There are two ways to close the white valve: suction and expansion
The function of the gas automatic shut-off valve is to automatically close when the gas is abnormal, preventing the continuous output of the gas.
When the gas pipe network stops, the pressure is too high, the gas is exhausted, and the hose falls off, the self-closing yan will automatically shut down.
When the reset knob of the gas self-closing valve is in the green line scale state, it is a normal gas state. At this time, the user can use the burners such as stoves and water heaters normally.
When the reset button rod of the gas self-closing valve is in the state of the red line, it proves that the pressure of the gas pipeline is too large, the self-closing valve is automatically closed (the reset button expands at this time), and the self-closing valve stops when the pipe network stops, the hose falls off, and the gas leaks. All are sucked and disconnected instead.
Many users are used to closing the pressure of the self-closing valve every time they use natural gas, which is not good. If the self-closing valve is frequently opened and closed, the self-closing valve will lose its function, resulting in gas leakage, which often fails to protect. In addition, there are also users who are hung on the self-closing valve stem or have foreign objects mixed in. In the long run, the self-sealing valve is in a normally open state and loses its protection function, which has hidden dangers.
After opening and closing the self-closing valve, the self-closing valve is prone to failure, causing gas leakage and no longer playing a protective role. In addition, some users hang on the self-closing valve stem or mix in foreign objects. For a long time, the self-closing throttle valve is in a normally open state, losing its protection function, causing hidden dangers.
The self-closing valve installed at home has been installed for a long time. How to check whether it is working properly? In the normal gas use state, first close the front valve of the clock. At this time, the gas source in the pipe is cut off, the stove is turned on, the gas pressure in the pipe drops sharply, the ordinary self-closing valve is automatically closed, the stove is cut off by the gas source, and the flame is extinguished. Then, turn off the switch on the stove, open the valve on the front of the clock, restore the gas supply, and relight the gas stove. If the stove does not catch fire, the self-closing valve is good. When a stove catches fire, it will prove to be faulty, be sure to entrust an expert to inspect and repair it.
In the above expression, we understand the household gas self-closing valve, but let's put it into practice. Only if you have a deeper understanding of the domestic gas self-closing valve, you can use it after you understand it.
The above is the correct use of the pipeline gas self-closing valve. If you want to know more, please feel free to contact us!
