Flow guide device for improving medium flow state at junction of branch pipeline and gathering pipeline

Abstract

The flow guiding device for improving the medium flow state at the junction of the branch pipelines and the gathering pipeline comprises the gathering pipeline, the branch pipelines and elbows, the branch pipelines are symmetrically arranged on the outer side of the gathering pipeline, and the elbows are arranged in the gathering pipeline; the gathering pipeline is a horizontally arranged circular pipeline; open holes used for installing the reinforcing connectors are symmetrically formed in the outer circle face of the gathering pipeline. A reinforcing joint is welded at the end part of the branch pipeline; and the neck part of the reinforcing joint penetrates through the open hole in the collecting pipeline and is connected with the open hole in a welding manner. By the adoption of the structure, the connecting mode is simple in structure and easy to achieve, the hedging phenomenon caused by the fact that media directly enter the gathering pipeline through the branch pipelines is avoided through the elbows arranged in the gathering pipeline, the media can be forcibly converged in the gathering pipeline, the flow state of the media is more stable, and the working efficiency is improved. And the pressure in the gathering pipeline is more uniform.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a diversion device for improving the flow state of the medium at the confluence of branch pipelines and collecting pipelines. Background technique [0002] In the chemical industry and other industries, it is often used that multiple branch pipes merge into a collection pipe. The branch pipeline and the collecting pipeline usually adopt the "feng"-shaped collecting structure. The angle between the branch pipeline and the collecting pipeline is 90°. When the angle between the branch pipeline and the collecting pipeline is 90°, the medium in the two opposite branch pipelines enters the collecting pipeline. After the pipeline, the medium hedges seriously in the collecting pipeline, which causes the unstable flow state of the medium and causes the pressure to fluctuate. like figure 1 As shown in the figure, in order to improve this situation, the existing branch pipes are improve...

Problems solved by technology

Branch pipes and collection pipes usually adopt a "Feng"-shaped collection structure, and the angle between the branch pipe and the collection pipe is 90°. When the angle between the branch pipe and the collection pipe is 90°, the medium in the two opposite branch pipes enters the collection After the pipeline, the medium is heavily hedged in the collection pipeline, resulting in unstable flow of the medium and resulting in pressure fluctuations

like figure 1 As shown, in order to improve this situation, the existing branch pipes are improved to 45° obliquely into the manifold connection, and usually the turning head is used to connect with the manifold. The processing of the joint here requires a whole piece of work material Turning to a specific angle and hollowing out the middle part of the cavity can meet the needs of use. Not only is it labor-intensive and wasteful, but also the large opening area on the collecting pipe wall greatly reduces the machining accuracy and increases the processing difficulty.
