The outer walls of the first connector 1 and the second connector 2 are respectively fixedly installed with a first pipeline 3 and a second pipeline 4. A fixing groove 16 is formed on the outer wall of the first connector 1, and the fixing groove 16 penetrates to the outside of the second connector 2. A bolt 5 is slidably connected to the inner wall of the fixing groove 16, and a nut 6 is threadedly connected to the outer wall of the bolt 5. Grooves 17 are formed on the opposite surfaces of the first connector 1 and the second connector 2, and an alarm component is arranged on the inner wall of the groove 17.

[0023] By setting the alarm component, in the process of use by the design staff, when natural gas leaks, an alarm will occur, thus attracting the attention of the staff and taking corresponding solutions, which can prevent the harm caused by natural gas leakage to people's physical health.

[0024] As Figure 2 shown, the alarm component includes a sensor 18. The outer wall of the sensor 18 is fixedly connected to the inner wall of the groove 17 close to the second connector 2. A fixing box 8 is fixedly connected to the outer wall of the second connector 2, and a battery slot 12 is formed on the outer wall of the fixing box 8. A battery 13 is arranged on the inner wall of the battery slot 12.

[0025] By setting the sensor 18, in the process of use, when natural gas leaks in the pipeline, the sensor 18 will give an alarm, thus attracting the attention of the staff and taking corresponding measures.
