Gas pipeline with automatic closing function

The invention discloses a gas pipeline with an automatic closing function. The gas pipeline with the automatic closing function comprises a first pipeline body, a second pipeline body and a sleeve connected between the first pipeline body and the second pipeline body in a sleeving mode. A first magnet used for sealing the first pipeline body is hinged to the lower portion of the end opening, in the sleeve, of the first pipeline body. A second magnet is rotatably connected to the outer wall surface of the upper portion of the sleeve. The magnetic poles of the first magnet and the second magnet are located at the upper end and the lower end correspondingly. The second magnet is connected with a thermosensitive metal wire. A probe at the other end of the thermosensitive metal wire is connected to a gas stove. The second magnet is connected with a motor. The motor is connected with an automatic control device. When a temperature detection signal is larger than the Curie temperature of the second magnet, a control
