Abstract

The invention relates to a bi-pass liquid pipe and a connecting structure thereof. The bi-pass liquid pipe comprises a first liquid delivery pipe body and a second liquid delivery pipe body, wherein the first liquid delivery pipe body is sleeved with the second liquid delivery pipe body; the inner wall of the first liquid delivery pipe body is connected with the outer wall of the second liquid delivery pipe body through an annular connecting plate; and a liquid flow channel is formed in the annular connecting plate. Due to the fact that the first liquid delivery pipe body and the second liquid delivery pipe body are connected through the annular connecting plate and the liquid flow channel is formed in the annular connecting plate to form a two-channel liquid delivery pipeline, when liquid with high temperature requirement is delivered, heat insulation liquid can be introduced between the first liquid delivery pipe body and the second liquid delivery pipe body to guarantee that required temperature is provided for liquid delivered in the middle liquid flow pipeline, and bidirectional or two-channel liquid delivery is facilitated. The bi-pass liquid pipe is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a double-pass liquid pipe and its connecting structure, belonging to the field of liquid conveying devices. Background technique [0002] The existing liquid transportation is single-channel transportation, and two transportation pipelines are used to realize two-way liquid transportation, resulting in too many pipelines, and for liquids that need to be kept warm, the temperature is difficult to control during pipeline transportation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-pass liquid pipe, which overcomes the need for more connecting pipelines in the prior art when transporting liquid in two directions and only uses some Simple insulation is used to protect against defects that cannot maintain the required temperature well. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a tw...
