Description

Self-heat-preservation pipe of pipeline heat-preservation system

Technical Field

The utility model relates to a pipe network heat preservation technical field especially relates to a self preservation temperature pipe of pipeline insulation system.

Background

The heat preservation pipeline is widely used for liquid and gas conveying pipe networks, central heating and heating networks, central air-conditioning ventilation pipelines, municipal engineering and the like. The heat-insulating pipeline is a powerful measure for heat supply and energy conservation, is safe and reliable, has lower construction cost, and has remarkable social benefit and economic benefit. At present, the heat insulation of the heat insulation pipeline is generally realized by wrapping a layer of heat insulation material outside a common pipeline. The heat insulating material is made of foam plastic or glass wool product. The heat insulation pipeline cannot ensure the integrity of the heat insulation pipeline in long-term use, and water is easy to enter in an open air state, so that the heat insulation performance of the heat insulation pipeline can be reduced, and the heat insulation effect is poor.

The application provides a self preservation temperature pipe can be used to the pipeline insulation system who has self preservation temperature function.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a self preservation temperature pipe can be used to the pipeline insulation system who has self preservation temperature function.

In order to achieve the above purpose, the technical scheme of the utility model is that: a self-heat-insulation pipe of a pipeline heat-insulation system comprises an inner pipe body and an outer pipe body which are concentrically arranged, wherein the end part of the inner pipe body extends to the outside of the outer pipe body by 3-10 cm, foaming glue is filled between the inner pipe body and the outer pipe body, and a glue injection hole for filling the foaming glue is formed in the outer pipe body; a support piece is also arranged between the inner pipe body and the outer pipe body, is sleeved outside the inner pipe body and is uniformly arranged along the length direction of the inner pipe body so as to ensure the filling thickness of the foaming adhesive; the interval between the supporting pieces is 50 cm-100 cm.

Furthermore, the support piece comprises a ring body sleeved outside the inner tube body, a plurality of support rods arranged along the radial direction of the ring body are arranged on the periphery of the ring body, and the support rods limit the distance between the outer tube body and the inner tube body.

The utility model has the advantages that: the utility model provides a self preservation temperature pipe can be used to the pipe insulation system that has self preservation temperature function, and this self preservation temperature pipe includes interior body, outer body to and fill including, the foaming glue between the outer body, interior body, outer body still are equipped with support piece, right the intertube distance of outer body and interior body is injectd, guarantees the packing thickness of foaming glue. The utility model discloses simple structure, preparation convenience utilize current PVC pipe fitting can make, during the construction, need not plus the heat preservation, and self foaming glue foaming is even, and it is effectual to keep warm, is difficult for taking place to leak, destruction phenomenon.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 1-2, a self-heat-insulating pipe for a pipeline heat-insulating system comprises an inner pipe body 1 and an outer pipe body 2 which are concentrically arranged, wherein the end of the inner pipe body 1 extends to the outside of the outer pipe body 2 by 5cm, foam rubber 3 is filled between the inner pipe body 1 and the outer pipe body 2, and a rubber injection hole 4 for filling the foam rubber 3 is formed in the outer pipe body 2; a support piece 5 is also arranged between the inner pipe body 1 and the outer pipe body 2, the support piece 5 is sleeved outside the inner pipe body 1 and is uniformly arranged along the length direction of the inner pipe body 1 so as to ensure the filling thickness of the foaming adhesive 3; the spacing between the supporting members 5 is 50-100 cm.

As shown in fig. 3, the supporting member 5 includes a ring body 51 sleeved outside the inner tube 1, a plurality of supporting rods 52 are disposed on the periphery of the ring body 51 along the radial direction of the ring body, and the supporting rods 52 limit the distance between the outer tube 2 and the inner tube 1.

The manufacturing method of the self-insulation pipe comprises the following steps:

1. taking a PVC pipe with the outer diameter of 5cm as an inner pipe body and a PVC pipe with the outer diameter of 10cm as an outer pipe body for later use;

2. manufacturing a supporting piece with the inner diameter of the ring body being 5cm for later use;

3. manufacturing a cylindrical end cover with the inner diameter of 10cm, wherein a hole is formed in the bottom of the end cover, is formed along the axis of the end cover and has the inner diameter of 5 cm;

4. sleeving a plurality of supporting pieces outside the inner pipe body, wherein the distance between the supporting pieces is 80 cm;

5. inserting the inner pipe body provided with the support into the outer pipe body, and extending the inner pipe body to the outside of the outer pipe body by 5 cm;
