Two-way corrugated compensation pipe

Abstract

The invention relates to a two-way corrugated compensation pipe. The two-way corrugated compensation pipe is provided with a telescopic pipe, wherein the telescopic pipe is provided with a corrugated pipe, an upper connecting pipe and a lower connecting pipe, and the upper end and the lower end of the corrugated pipe are connected with the upper connecting pipe and the lower connecting pipe in a closed mode respectively; the upper end and the lower end of the telescopic pipe are respectively and fixedly connected with a flange; a large-caliber flow guiding barrel and a small-caliber flow guiding barrel are arranged in the telescopic pipe in a sliding mode; the small-caliber flow guiding barrel is sleeved with the large-caliber flow guiding barrel in a sliding mode; the large-caliber flow guiding barrel is provided with a fixed end and a non-fixed end, the end opening of the fixed end of the large-caliber flow guiding barrel is fixedly connected with the inner wall of the lower connecting pipe on the telescopic pipe; the small-caliber flow guiding barrel is provided with a fixed end and a non-fixed end, and the end opening of the fixed end of the small-caliber flow guiding barrel is fixedly connected with the inner wall of the upper connecting pipe on the telescopic pipe. The two-way corrugated compensation pipe is simple in structure, not prone to temperature distortion and wide in application range.

Description

technical field [0001] The invention relates to a compensation pipe, in particular to a bidirectional corrugated compensation pipe. Background technique [0002] As we all know, the compensation tube is equivalent to a compensation element, and the bellows are used on the compensation tube because the bellows can be easily bent, elongated and compressed, thus compensating the displacement pipeline. Because the corrugated pipe has many folds, it is easy to hide dirt, which causes various hygiene problems. Furthermore, due to the insufficient rigidity of the bellows, the compensation pipe is prone to deformation. Although there are corrugated pipes with stable structures at present, these stable structures are relatively complicated and affect the appearance of the compensation pipe. [0003] At present, the compensation pipe generally only has one-way scalability, and the scope of application is not very wide. Moreover, the bellows are easily deformed by heat. Contents o...
