Pipeline internal recycling device

Abstract

The invention provides a pipeline internal recycling device. The pipeline internal recycling device comprises a first son-mother pipe conversion tee-joint and a second son-mother pipe conversion tee-joint which are the same in structure. The first son-mother pipe conversion tee-joint and the second son-mother pipe conversion tee-joint respectively comprise a transverse pipe and a vertical pipe vertically installed on the wall of the transverse pipe and communicated with the transverse pipe, wherein the transverse pipe is internally provided with a son pipe, one end of the son pipe is located in the opening of the transverse pipe, the other end of the son pipe is communicated with the vertical pipe, and the wall of the part, located in the opening of the transverse pipe, of the transverse pipe is provided with an inner port. The outer port of the vertical pipe of the first son-mother pipe conversion tee-joint is communicated with one end of a first connecting pipe, the other end of the first connecting pipe is communicated with the water inlet of a water pump, the water outlet of the water pump is communicated with one end of a second connecting pipe, the other end of the second connecting pipe is connected with the outer port of the vertical pipe of the second son-mother pipe conversion tee-joint. The pipeline internal recycling device is installed on branches of a pipeline circulating system in a matched mode, and effective circulation can be formed through the branches and a main pipeline.

Description

technical field

[0001] The invention relates to the technical field of pipelines, in particular to a pipeline internal circulation device capable of forming internal circulation of liquid in a one-way closed pipeline. Background technique

[0002] In the prior art, if a circulation pipeline is composed of a main circulation and several branch lines, then each branch line cannot participate in the circulation of the main circulation line during operation, resulting in that the branch line liquid may not be able to match the main circulation in terms of temperature, concentration, etc. The liquid in the line remains consistent. Contents of the invention

[0003] The invention provides a pipeline internal circulation device, which can form an effective circulation between each branch line and the main line when it is matched with the branch lines of the pipeline circulation system.

[0004] In order to achieve the above object, the present invention provides the following te...
