The extension block 707 on one side of the first fixed shell 701 and the second fixed shell 702 is pulled closer by the use of the screw 703 and the nut 704, so that the extension block 707 can drive the first rubber ring 705 and the second rubber ring 706 of the inner cavity of the first fixed shell 701 and the second fixed shell 702 to fit the surface of the inlet pipe 5, the outlet pipe 6 and the connecting column more closely. 2 is tightly connected. When natural gas leaks at the connection between the connecting sleeve 3 and the connecting column 2, the leaked natural gas can be transported to the second delivery pipe 709 through the first delivery pipe 708 connected to the inner cavity of the first fixed shell 701. When the leaked natural gas reaches the top of the second delivery pipe 709, it will reach the induction probe 12 and will be detected by the sensor host 8 that is always working. When the sensor host 8 detects the leaked natural gas, the module built into the sensor host 8 will be linked to the buzzer 9 to alarm and remind the family members to avoid further accidents. The fixing seat 14 and the support plate 13 are provided to support and fix the sensor host 8 to avoid the sensor host 8 from falling off during use, resulting in the inability to timely detect the natural gas leak. When a warning is detected, a sensor host 8 and a clamp ring 10 are set, and the clamp ring 10 is used to connect the sensor host 8 with the induction probe 12. Different clamp rings 10 and induction probes 12 can be replaced according to different connecting pipes 710. A threaded rod 11 and the induction probe 12 are set, and the threaded rod 11 can be used to connect with the connecting rod.

The display panel 15 can allow users to clearly see the energy value of the natural gas. When the user wants to read the value, the display button 18 can be pressed to make the display panel 15 display the value. The value is easy to record and read. After the display panel 15 is displayed for a certain period of time, the screen will automatically turn off to avoid power consumption. A card slot 16 and a battery compartment 17 are set. The card slot 16 can be used to facilitate users to use cards to recharge natural gas energy for their own natural gas accounts at any time. A battery installed in the battery compartment 17 can power the energy meter body 1 and the display panel 15, avoiding direct or indirect contact between the energy meter body 1 and natural gas using household electricity, and avoiding accidents caused by leakage of electricity and gas. Hydrogenated nitrile rubber is nitrile rubber with some double chains removed after hydrogenation. After hydrogenation, it has high temperature resistance, oil resistance and weather resistance.
