What happens when the gas tank reaches the pressure safety valve but does not open?
The three elements of the gas storage tank, safety valve, pressure gauge, and sewage valve are indispensable, and any problem with one component may cause a major accident. After the gas tank reaches the specified pressure, the safety valve is not open, so it is very dangerous. Let us understand the reason for this.
If you find such a situation, you should not sit back and ignore it. You need to adjust and grind the valve seat and the valve core to make it fit in time, properly widen the gap between the valve stem and the outer casing, or reinstall the safety valve to remove debris in time. Clean up.
In order to ensure the safety and reliability of the gas storage tank, the safety valve and pressure gauge need to be inspected annually or semi-annually according to regulations. The inspection and adjustment of the safety valve needs to be carried out on a regular basis. Usually, the lever is pulled loosely for about three months, and the safety valve is closed and opened again.
