AI Technical Summary
In existing natural gas transmission systems, solenoid valves rely on external power supply. When power is cut off, they cannot regulate gas pressure, leading to abnormal increases in gas pressure and posing safety hazards.
A stable power supply component is used to convert the natural gas flow into electrical energy, which is then used to power the battery through a generator, rectifier, and charging controller. Combined with a gas pressure monitoring component, the opening of the solenoid valve is adjusted in real time to achieve stable gas pressure control.
Even in the event of a power outage, the air pressure can be adjusted in real time to ensure the safety of transportation and prevent accidents such as pipeline explosions and leaks.
