pipeline

Abstract

The invention provides a pipeline. The pipeline comprises a first pipe, a second pipe and a pipe connecting mechanism, and the pipe connecting mechanism comprises a stretching pipe, a first bellows, a transition flange disc, a second bellows, a clamping sleeve and a third bellows, wherein the stretching pipe communicates with the first pipe and the second pipe, and the first bellows, the transition flange disc, the second bellows and the clamping sleeve are connected to the stretching pipe in a sleeving manner; the flange end of the stretching pipe is fixed with the flange end of the first pipe, the pipe end of the stretching pipe partially extends into the second pipe, and the flange end of the stretching pipe, the first bellows, the transition flange disc, the second bellows and the flange end of the second pipe are fixedly connected in sequence, wherein a cone-shaped hole is formed in the transition flange disc, the clamping sleeve is connected to the stretching pipe in a sleeving manner, and the taper of the clamping sleeve is equal to that of the cone-shaped hole in the transition flange disc; and the third bellows is connected to the first pipe in a sleeving manner, one end of the third bellows is fixed with a flange fixed to the first pipe, and the other end of the third bellows is fixedly connected with the first bellows. According to the pipeline, broken first bellows can be replaced by the third bellows, and the loss caused by shutdown maintenance is avoided.

Description

technical field [0001] The invention relates to a pipeline, in particular to a pipeline used for gas-liquid medium transmission and meeting the requirements of thermal expansion and cold contraction. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. [0003] It can be understood that in the process of pipeline transporting medium, according to the temperature of the medium it transports, it will cause the physical phenomenon of thermal expansion and contraction of the pipeline itself; To cause cracking, corrugated pipes are installed between the segmented pipes, and the expansion and contraction characteristics of the bellows are used to offset the deformation of the pipes due to thermal expansion and contraction. [0004] The above solution solves the technical problem of cracking when the pipeline expands with heat and contracts with cold, but it also causes new ...

AI Technical Summary

Problems solved by technology

[0004] The above solution solves the technical problem of cracking when the pipeline expands with heat and contracts with cold, but it also causes new problems. Since the bellows are connected between two segmented pipelines, that is, the bellows also play a role. When it comes to the function of conveying medium, if the corrugated pipe cracks, it is required to stop the transmission of the pipeline to the medium before replacing the new corrugated pipe, that is, it needs to stop production for maintenance, which will cause great losses to production enterprises.
