[0041] 3.

After monitoring the entry of oxygen and fuel gas into the ignition tube (5), the sensor detection head (6442) of the gas sensor body (6441) is retracted into the housing (641), and the fuel gas is ignited at the port of the ignition tube (5) through the ignition needle (4), so as to control the gas pipe (1) to pass the gas, and ignite the ignition burner at the end of the gas pipe (1) through the ignition tube (5); After the ignition burner is ignited, the ignition gas source valve (8), the solenoid valve 1 (10) and the solenoid valve 2 (11) are closed to turn off the ignition tube (5). The sensor detection head (6442) of the gas sensor body (6441) is inserted into the straight tube (61) to monitor the oxygen and fuel gas concentrations inside the ignition tube (5). If the concentrations are too high, it is determined that the oxygen and fuel gas are leaking, and the pipeline is inspected and repaired.
