Since carbon dioxide is heavier, the air in the hydrogen energy pipeline is discharged through the first exhaust port by utilizing carbon dioxide. Subsequently, the first exhaust port is closed and the second exhaust port is opened to inject hydrogen into the pipeline. Since hydrogen is lighter than carbon dioxide, hydrogen floats on the top of the pipeline and carbon dioxide is discharged through the second exhaust port, thereby purifying the hydrogen in the hydrogen energy pipeline. The utility model solves the problem that in the installation process of the traditional hydrogen energy pipeline, the oxygen in the pipeline cannot be completely discharged, resulting in unnecessary safety hazards when hydrogen is transported mixed with oxygen.

[0027] In this embodiment, the purification tube 5 is installed at one end of the hydrogen energy pipeline 4, and the valve body 6 arranged at one end of the inner wall of the purification tube 5 is rotated. Since the valve body 6 is spherical in shape and has a cavity at the center, the valve body 6 is rotated in the purification tube 5 by turning the handle 7, so that the cavity surface fits the inner wall of the purification tube 5, thereby closing the purification tube 5. At this time, the first exhaust port 8 is opened, and carbon dioxide is injected into the purification tube 5 from the intake pipe 10.

Then the first exhaust port 8 is closed, and the second exhaust port 9 is opened to inject hydrogen into the pipeline. Since hydrogen is lighter than carbon dioxide, hydrogen floats on the top of the pipeline, so that carbon dioxide is discharged through the second exhaust port 9, thereby purifying the hydrogen in the hydrogen energy pipeline 4, solving the problem that in the installation process of the traditional hydrogen energy pipeline 4, the oxygen in the pipeline cannot be completely exhausted, resulting in unnecessary safety hazards when hydrogen is transported mixed with oxygen.

At this time, a screw 14 is inserted into a screw hole 13 provided at one end of the sealing closed loop 12, so as to fix the sealing closed loop 12.

[0031] Example 4

[0032] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, one end of the purification tube 5 away from the hydrogen energy pipeline 4 is plugged into one end of the fixed tube 2, and both ends of the outer wall of the fixed tube 2 are threadedly connected with fixing nuts 15, and one end of the fixing nut 15 is threadedly connected to the outer wall of the purification tube 5.

[0033] In this embodiment, the end of the purification tube 5 away from the hydrogen energy pipeline 4 is inserted into the fixed tube 2, and the fixing nuts 15 arranged at both ends of the outer wall of the fixed tube 2 are used to fix the purification tube 5 and the fixed tube 2.

[0034] The following is a detailed description of the working principle of the easily disassembled hydrogen pipeline.

By turning the handle 7, the valve body 6 is rotated in the purification tube 5 so that the cavity surface fits the inner wall of the purification tube 5, thereby closing the purification tube 5. At this time, the first exhaust port 8 is opened, and carbon dioxide is injected into the purification tube 5 from the air inlet pipe 10. Since carbon dioxide is heavier, carbon dioxide is used to discharge the air in the hydrogen energy pipeline 4 through the first exhaust port 8. Then the first exhaust port 8 is closed, and the second exhaust port 9 is opened to inject hydrogen into the pipeline. Since hydrogen is lighter than carbon dioxide, hydrogen floats on the top of the pipeline, so that carbon dioxide is discharged through the second exhaust port 9, thereby purifying the hydrogen in the hydrogen energy pipeline 4, solving the problem that during the installation of the traditional hydrogen energy pipeline 4, the oxygen in the pipeline cannot be completely exhausted, resulting in unnecessary safety hazards when hydrogen is transported mixed with oxygen.
