Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection devices, in particular to a detection device for thermal insulation pipes. Background Art

[0002] Insulated pipe is the abbreviation of insulating pipe. Insulated pipe is used for the transportation of liquid, gas and other media. It is used for thermal insulation of pipelines in petroleum, chemical, aerospace, hot springs, etc. After the production of the insulation pipe is completed, the air tightness of the insulation pipe needs to be checked.

[0003] After searching, the publication number is CN220170467U. A thermal insulation pipe air tightness detection device relates to the field of pipeline detection devices, including two groups of fixed blocks and pipelines outside thereof, and the two groups of fixed blocks are fixed with sealing airbags matching the inner wall of the pipeline on the outer side. When the external vacuum equipment takes air into the center tube, the gas inflates the sealing airbag, and then the sealing airbag expands and fits with the inner wall of the pipeline, thereby forming a seal on the end of the pipeline. When the external vacuum equipment evacuates the center tube, the one-way valve is closed at this time, and the sliding sealing block is separated from the conical rod under the action of the air extraction, so that a gap is formed between the inner wall of the sliding sealing block and the outer side of the conical rod. That is to say, the vacuum equipment can perform a vacuum operation on the inside of the pipeline, and then the sealing of the pipeline can be detected. As can be seen from the above, not only can the two ends of the pipeline be blocked more conveniently, the overall operation is more convenient, and it is convenient to perform air tightness detection on the pipeline.
