90-degree bent pipe guide piece arrangement method

Abstract

The invention discloses a 90-degree bent pipe guide piece arrangement method. The 90-degree bent pipe guide piece arrangement method comprises a 90-degree bent pipe, a guide piece A and a guide piece B. Two guide pieces are arranged in the 90-degree bent pipe, and are respectively the guide piece A and the guide piece B; the guide piece A is near the inner side of the bent pipe; and the guide piece B is near the outer side of the bent pipe. The guide pieces are arranged according to a golden ratio, that is, the guide piece B is arranged in the inner diameter place of the bent pipe from the inner wall of the outer side of the bent pipe by 0.618 time, and the guide piece A is arranged on the guide piece B from the inner wall of the inner side of the bent pipe by 0.618 time in the longitudinal section of the bent pipe. In the fluid flowing direction, after the guide piece B passes through the bent pipe, one part of extension section is generated; and the distance of the extension section is 0.3 time of the inner diameter of the bent pipe. The guide pieces in the bent pipe are reasonably arranged to reduce or eliminate complex flowing conditions in an elbow, so that the flowing field distribution is effectively improved, the pipe noise caused by unstable flowing is reduced, the reliability of the bent pipe is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a method for arranging deflectors of a 90° elbow, belonging to the technical field of industrial pipeline systems. Background technique [0002] With the advancement of science and technology in our country, the rapid development of industry and agriculture, and the increasing perfection of the modernization process, pipeline systems are widely used in many fields, such as urban water supply pipelines, heating systems, oil pipelines, nuclear power plant water circulation systems, etc. These pipeline systems are of great importance to the people. The guarantee of the quality of life plays a very important role in the healthy development of the national economy, so it is necessary to ensure the stability of pipeline transportation. [0003] Elbow is an important component in the pipeline system. It has the function of changing the flow direction of the transmission medium and can play the role of adjusting the installation positi...

AI Technical Summary

Problems solved by technology

If the number of deflectors is too small, the improvement of the flow field will not be obvious. If the number is too large, although it can play an obvious role in diversion, but the local resistance is too large, it will affect the fluid flow.
