Abstract
The utility model relates to an underground three way pipe with little thermal shiftness for heat transmission, which is designed for improving the defects that the existing underground three way pipe for heat transmission has big thermal shiftness, and the thermal insulation layer on a heat transmission branch pipe is easy to be broken by extrusion. The utility model is provided with a main inner pipe, which is welded with a branch inner pipe, and the outer sleeve pipe of the branch inner pipe is communicated with the outer sleeve pipe of the main inner pipe in welding way. A thermal insulation material is respectively provided between the branch inner pipe and the outer sleeve pipe of the branch inner pipe and between the main inner pipe and the outer sleeve pipe of the main inner pipe. The underground three way pipe with little thermal shiftness for heat transmission is characterized in that a barrier ring is connected between the main inner pipe and the outer sleeve pipe of the main inner pipe in welding way. The barrier ring is a cone surface shaped steel plate ring. The barrier ring effectively prevents the thermal shiftness in the main inner pipe and the branch inner pipe, making the thermal insulation material layer on the heat transmission branch pipe be not broken by extrusion. The utility model can be widely used for the system of the underground pipe for heat transmission.
Description
(1) technical field
The utility model relates to the accessory that buries ground heating power conveyance conduit, is specially the little ground heating power that buries of thermal walking and carries the threeway pipeline section.
(2) background technique
After buried heat transfer pipeline installed, necessary butt welded seam etc. were made film and are detected a flaw, and the threeway pipeline section is installed can the butt welded seam film making be detected a flaw, and can also connect on the other hand being in charge of of heating power conveying.The threeway pipeline section as shown in Figure 1 in the prior art, when it is installed on the heating power conveyance conduit, pipe is communicated with interior pipe 7 welding of heating power conveyance conduit in the master of threeway 6, an interior pipe of threeway 6 is welded to connect the heating power conveying and is in charge of 5, heating power is carried and to be in charge of 5 outer tube 3 and to weld with heating power exterior coating of pipe line pipe 8 and be communicated with, described heating power be in charge of 5 and its outer tube 3 between the device thermal insulation layer 4, because the interior pipe 7 of heating power conveyance conduit temperature difference under operation and non-operating state is big, generation is expanded with heat and contract with cold, interior pipe 7 produces thermal walkings in outer tube 8, interior pipe 7 is made axial slip, pipe also can be followed thermal walking in the master of the threeway pipeline section 6 that welds mutually with interior pipe 7, threeway 6 in pipe and heating power carry be in charge of 5 will push thereupon its with an outer tube 3 between the heat-preservation cotton layer 4 of filling, heat-preservation cotton layer 4 is easily crowded broken, the use of threeway pipeline section is unreliable and dangerous.
(3) summary of the invention
For the heating power of existing buried heating power convey three-way pipeline section carry be in charge of and its outer tube between the heat-preservation cotton layer easily squeeze broken shortcoming, the utility model provides a kind of thermal walking little buried heating power convey three-way pipeline section, it can reduce heating power and carry main inner tube and heating power to carry the thermal walking of branch inner tube, heating power is carried under main inner tube operation and the non-operating state, it is broken that heating power carries the heat preserving and insulating material layer between branch inner tube and the outer tube thereof can not be squeezed, thus the dependability and the security that have improved the threeway pipeline section.
Technical solutions of the utility model are as follows: it has main interior pipeline section, be welded to connect pipeline section in the branch in main on the pipeline section, the outer sleeve of pipeline section is communicated with the outer sleeve welding of main interior pipeline section in dividing, install thermal-protective material respectively between pipeline section and its outer sleeve and between main interior pipeline section and its outer sleeve in dividing, it is characterized in that being welded to connect catch ring between the interior pipeline section of described master and its overcoat pipeline section.Its further feature is a cone-shaped steel plate ring at described catch ring.
The utility model in use, the two ends of pipeline section carried the inner tube of being responsible for to be welded to connect with buried heating power respectively in it was main, the inner tube that the termination of pipeline section and the conveying of buried heating power are in charge of in dividing is welded to connect.Owing to be provided with structure characteristic described in the technique scheme in the utility model and the catch ring of feature be installed, can effectively block the thermal walking of pipeline section in the utility model master, thereby effectively reduce the thermal walking that the utility model divides interior pipeline section, make the heat preserving and insulating material layer between the interior pipeline section of branch and its outer sleeve can not be squeezed broken, improve the operational safety and the Security of threeway pipeline section, realized the purpose of this utility model thus.
(4) description of drawings
Fig. 1 is the axial cutaway view of existing three-way pipe segment structure;
Fig. 2 is the axial sectional view of the utility model structure.
(5) embodiment
See Fig. 2, the utility model has main interior pipeline section, is welded to connect pipeline section in the branch on the main interior pipeline section.Pipeline section is welded to connect pipeline section 1,7 respectively by the person in charge two ends of reducing T 6 and constitutes in main; Pipeline section constitutes by being welded to connect pipeline section 5 being in charge of of reducing T 6 in dividing.The outer sleeve 3 of pipeline section is communicated with outer sleeve 8 welding of main interior pipeline section in dividing.Install respectively insulation material layer 4 and 2 between pipeline section and its outer tube 8 between pipeline section and its outer tube 3 and in main in dividing, insulation material layer 4 and 2 respectively and have little gap between described outer tube 3 and 8.Be welded to connect catch ring 9 between pipeline section and its outer sleeve 8 in above-mentioned master, as most preferred embodiment, this catch ring 9 is made cone-shaped steel plate ring, and the medial and lateral of catch ring 9 are insulation material layer 2.The utility model in use, the pipeline section 1 and 7 at its main inner tube two ends carries the inner tube of trunk line to be welded to connect with buried heating power respectively, its minute the pipeline section 5 of inner tube carry the inner tube of being in charge of to be welded to connect with buried heating power.
Claims (2)
1. the little buried heating power convey three-way pipeline section of thermal walking, it has main interior pipeline section, be welded to connect pipeline section in the branch in main on the pipeline section, the outer tube of pipeline section is communicated with the outer tube welding of main interior pipeline section in dividing, install respectively heat-barrier material between pipeline section and its outer tube and between main interior pipeline section and its outer tube in dividing, it is characterized in that being welded to connect catch ring between the interior pipeline section of described master and its overcoat pipeline section.
