a plug-in pipe

Abstract

The invention relates to a splicing type pipeline. The splicing type pipeline comprises a first pipeline, a second pipeline and a pipeline connecting mechanism, wherein the pipeline connecting mechanism comprises a third pipeline, a first corrugated pipe, a transitional flange plate and a second corrugated pipe, and the first corrugated pipe, the transitional flange plate and the second corrugated pipe sleeve the third pipeline; a flange end of the third pipeline is fixedly connected to a flange end of the first pipeline, and part of a pipeline end of the third pipeline extends into the second pipeline; one end of the first corrugated pipe is fixedly connected to the flange end of the third pipeline, and the other end of the first corrugated pipe is fixedly connected to a first end of the transitional flange plate; the second corrugated pipe is connected and fixed to a second end of the transitional flange plate and a flange end of the second pipeline by long bolts; and a convex ring is fixed to the pipeline end, which is arranged in the position of the second corrugated pipe, of the third pipeline, and the height of the convex ring is greater than the spacing between the second end of the transitional flange plate and the pipeline end of the third pipeline. According to the splicing type pipeline, while medium transmission is not stopped, the first corrugated pipe is directly replaced, so that loss, caused by a halt in production for maintenance, of an enterprise is avoided.

Description

technical field [0001] The present invention relates to a connection type pipeline. Background technique [0002] A pipeline is a device for conveying gas, liquid or fluid with solid particles connected by pipes, pipe joints and valves. [0003] It can be understood that in the process of transporting the medium, the pipeline will cause the physical phenomenon of thermal expansion and contraction of the pipeline itself according to the temperature of the medium it transports. To cause cracking, bellows 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 is thermally expanded and contracted, but it also causes new problems. Since the bellows is connected between two segmented pipelines, the bellows also plays When the function of conveying the m...

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.
