The working principle of the electronic control of the shut-off valve:
The shut-off valve is a safety protection Valve installed on the liquefied petroleum gas (gas), liquid phase and gas phase pipelines, and used in conjunction with a remote gas source. The gas source control valve is opened-closed to occur on the pipeline or the storage tank. When a large amount of leakage or even a fire occurs, the gas source is quickly and manually relieved, or the fusible alloy is melted when the temperature is ≥75%% p5C%%D, and the cylinder is automatically relieved, and the valve is quickly closed to stop leakage, which serves as a safety protection function.
The working principle of the electronic control of the shut-off valve:
The valve air inlet is installed with a two-position three-way solenoid valve, and the remote electrical console is used to control the valve switch.
1. The gas leakage alarm is energized, the solenoid valve is energized and exhausted, and the valve is automatically closed.
2. Manually control the solenoid valve (press the red Clamp) to vent, the valve automatically closes.
