An in-line circulation device

Abstract

A pipeline internal circulation device, comprising a water pump (201), a first primary and secondary pipe switching T-joint (101) and a second primary and secondary pipe switching T-joint (105), the first primary and secondary pipe switching T-joint (101) and the second primary and secondary pipe switching T-joint (105) having the same structure. The first primary and secondary pipe switching T-joint (101) comprises a first transverse pipe (102) and a first longitudinal pipe (112) that is perpendicularly installed on the wall of the first transverse pipe (102) and is communicated with the first transverse pipe (102). The first transverse pipe (102) is internally provided with a first secondary pipe (111), one end of the first secondary pipe (111) is located at the port of the first transverse pipe (102), the other end of the first secondary pipe (111) is communicated with the first longitudinal pipe (112), and a first secondary pipe inner adaptor (103) is provided on the wall of the first secondary pipe (111) located at the port of the first transverse pipe (102). The first secondary pipe (111) and the first longitudinal pipe (112) form secondary passages of the first primary and secondary pipe switching T-joint (101), the first transverse pipe (102) serves as a primary passage of the first primary and secondary pipe switching T-joint (101), and the first secondary pipe inner adaptor (103) is used for connecting secondary pipes of other pipelines. The device is installed on branches of a pipeline circulation 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...
