Description

Technical Field

[0001] The utility model relates to the field of gas engineering, and more specifically to a pipeline blocking mechanism for gas engineering installation. Background Art

[0002] For example, the announcement number CN217003657U discloses a pipeline sealing device for urban gas projects, comprising: a column, the column is inserted into the pipeline, a sealing cover is provided on the outside of the pipeline, an air inlet pipe is provided on the top of the sealing cover, an air bag for sealing the pipeline is provided on one side of the column, and the column and the pipeline are relatively sealed; an expansion mechanism, the expansion mechanism is installed on the inner wall of the pipeline, the expansion mechanism supports the side of the air bag, so that the air bag seals the pipeline after expansion. The utility model has a smaller hole in the pipeline, which is convenient for the staff to seal the column and the air bag to seal the pipeline, and it can also facilitate the air bag to stably seal the pipeline.

[0003] It can be seen from the above-mentioned public scheme that the current pipeline sealing mechanism will isolate the internal shielding seal of the pipeline through the baffle plate when sealing. However, the impact force of the gas will cause the baffle plate to deflect to the side where there is no gas impact force. Therefore, if the baffle plate has poor limiting stability, it is easy to fail to seal and then the gas will flow. At the same time, some existing pipeline sealing mechanisms are fixed on the gas circulation pipeline, and it is not easy to replace the pipeline sealing mechanism, which brings a lot of inconvenience to use.
