Beschreibung
Zusammenfassung:	The utility model discloses an intelligent control fuel gas self-closing valve which comprises a first auxiliary pressure relief discharging device, a main conveying device and a second auxiliary pressure relief discharging device, and the main conveying device is distributed between the first auxiliary pressure relief discharging device and the second auxiliary pressure relief discharging device. The first auxiliary pressure relief and discharge device and the second auxiliary pressure relief and discharge device are the same in structure, and the main conveying device comprises a pressure detection valve, a first fixed connecting disc, a controller, a conveying pipe and a first electric valve. The controller can control the second electric valves in the first auxiliary pressure relief and discharge device and the second auxiliary pressure relief and discharge device to synchronously stop running, so that the first electric valve is always in a safe state in the using process, and the phenomena of air leakag
