Pictures of gas self-closing valve

Picture of gas self-closing valve:

The natural gas self-closing valve will prevent the output of gas under abnormal conditions. The self-closing valve will shut down when the pipeline network stops gas or the pressure is too high. The valve will automatically close.

Pipeline gas self-closing valve, referred to as self-closing valve, is installed on the low-pressure gas system pipeline. When the pipeline gas supply pressure appears under or overpressure, it can automatically close without electricity or other external power. and must be opened manually.

The self-closing valve installed at the connection between the end of the pipeline and the hose behind the gas meter should have a pressure loss closing function. The self-closing valve for pipeline gas is suitable for pipeline natural gas, liquefied petroleum gas, and artificial gas.

Natural gas self-closing valve status description

1. In the normal state, the self-closing valve reset button pull rod will be in the green line scale state.

2. When the red line on the reset button pull rod pops up, it means that the pressure in the gas pipeline is too high, and the self-closing valve will close by itself.

3. When the reset button and pull rod are all retracted, it means that the pipeline network has stopped gas or the gas hose has fallen off, and the self-closing valve will also close by itself.
