Description

Technical Field

[0001] This utility model belongs to the field of petrochemical pipeline sampling technology, and specifically relates to an automatic sampling device for pipeline media. Background Technology

[0002] Petrochemical pipelines are specialized pipeline systems used to transport petroleum, chemical products, and their derivatives. These pipelines play a crucial role in the petroleum and chemical industry, primarily connecting production facilities, storage tank farms, and transportation terminals to ensure the safe and efficient transport of raw materials, intermediates, and finished products. Sampling of media within petrochemical pipelines is mostly done manually, involving multiple sampling points using sampling bottles and tubes. After sampling, the samples are placed in storage containers for analysis. This method suffers from low efficiency due to the multi-point sampling process, requiring personnel to repeatedly travel to multiple sampling points, resulting in high labor intensity. Furthermore, the repetitive nature of manual sampling in later stages leads to decreased concentration and fatigue, potentially causing deviations from the planned sampling procedures and resulting in sampling errors.

[0003] In summary, there are some problems with manual sampling of media inside petrochemical pipelines. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
