[0029] Working principle: when using the gas pipeline connecting device, first select the appropriate connecting port according to the pipe diameter of the pipeline to be connected. If it is a large diameter pipeline, insert it into the large diameter connecting end 11; if it is a small diameter pipeline, insert it into the small diameter connecting end 12. During insertion, the pipeline is in close contact with the sealing gasket 21, and the sealing rubber layer 22 further fills the gap between the two, providing preliminary sealing. At the same time, the sealing ring 23 also provides further sealing for the pipeline, forming multiple sealing protection. Then, pass the fastening bolt 31 through the through hole of the mounting lug plate 33, install the elastic washer 34 on the fastening bolt 31, and then use the tool to tighten the fastening nut 32. With the tightening of the fastening nut 32, the elastic washer 34 will be elastically deformed, providing a certain pre-tightening force, making the pipeline connection at both ends of the connecting body 1 more tightly, preventing the pipeline from loosening during gas transmission. During gas transmission, the operator can observe the gas transmission inside the connecting device through the observation window 4 at any time, such as whether there is leakage, whether the gas flow is normal, etc. If problems are found, appropriate measures can be taken to deal with them in time. When the pipeline needs to be maintained, repaired or replaced, only the fastening nut 32 needs to be loosened with a tool, and the connecting device can be easily removed, completing the disassembly of the pipeline. The entire installation and disassembly process is relatively simple, reducing maintenance costs and downtime. At the same time, the reinforcing ribs 5 on the outer wall of the connecting body 1 can enhance its structural strength, ensuring its reliability in high-pressure gas transmission environment, and prolonging the service life of the device.
