Description

Horizontal limit structure of clearance-adjustable pipeline

Technical Field

The utility model relates to a horizontal limiting structure of a gap-adjustable pipeline, and belongs to the technical field of pipeline supporting and hanging frames.

Background

At present, the radial limiting device of the pipeline is widely applied to steam-water and petrochemical pipeline systems, is a common pipeline displacement control structure, and has the functions of limiting (or guiding) pipeline displacement and controlling or reducing pipeline vibration. According to the numerical value of the control position of the radial limiting device, the radial limiting device can be divided into a gapless limiting device (the allowable displacement is zero) and a gapped limiting device (the allowable displacement is within a limiting range), radial limiting structures on the existing design manual are all fixed by one-time welding, and once gap deviation occurs on site, the original structure needs to be welded again after being cut, so that the adjustment workload is large. And because of manufacturing dimensional errors or field installation errors (including positioning deviation of rooting beams, actual positioning axis deviation of pipelines and the like), the field limiting gap is often deviated from a design requirement value, and particularly, for a gapless limiting device (the design generally requires that the gap value is controlled within 2 mm), because too small gaps often enable parts to be just plugged into a limited space, the field inspection often finds that the limiting gap is between 10 and 20mm and even larger, so that the radial limiting cannot play a due design role.

In view of the above-mentioned drawbacks, the present inventors have actively studied and innovated to create a horizontal spacing structure for a gap-adjustable pipeline, which has a more industrial utility value.

The distance between the limiting support panel and the limiting pipe clamp can be adjusted by screwing the upper limiting support sleeve and the lower limiting support sleeve, so that the purpose of radial limiting gap adjustment is achieved.
