Abstract
The invention discloses a composite insulating pipe which relates to the technical field of water heating pipe manufacturing. The composite insulating pipe comprises an inner pipe and an outer pipe sleeved outside the inner pipe, wherein a plurality of brackets are arranged between the inner pipe and the outer pipe, the cavity between the inner pipe and the outer pipe is divided into a plurality of chambers by the plurality of brackets, and each chamber is filled with insulating materials; the brackets are uniformly arranged between the inner pipe and the outer pipe; and the insulating materials are polyurethane. Compared with the prior art, because the directly molded fixed brackets are adopted to the outer pipe or the inner pipe, the coaxiality of the inner pipe and the outer pipe can be guaranteed during sleeving the pipes, the uniformity of the thickness of an insulating layer is guaranteed, and the insulating performance of the composite insulating pipe is improved.
Description
Technical field
The present invention relates to hot-water heating tubing manufacturing technology field, especially a kind of medium that is used for various pipelines such as heat supply is incubated the pipe of transmission.
Background technique
Compound thermal insulating pipe divides three layers from the inside to surface, and first layer is a working pipe, generally selects atactic copolymerized polypropene (PPR) pipe for use; The second layer is a polyurethane insulation coating, and the 3rd layer is protective tube, selects PVC-U (PVC) pipe for use; The existing compound thermal insulating pipe technological scheme of using always is: have and manage and be enclosed within the outer outer tube of pipe in this in one, said interior the pipe is coated with isolating frame along the medium feeding direction at a distance from a segment distance, and this isolating frame outer surface radially has the many width of cloth to penetrate the object of bar; Be filled with thermal insulating material in the cavity in said between pipe and the said outer tube.In use there is following deficiency in this compound thermal insulating pipe technological scheme: 1, because compound thermal insulating pipe is between inner and outer pipes, to wear an isolating frame at a distance from a segment distance inner and outer pipes is separated; Away from or do not have in the position of isolating frame pipe big with the error of outer coaxial tube degree; The even phenomenon of became uneven can appear in the polyurethane in therefore injecting around the pipe, thereby influences the thermal insulation property of compound thermal insulating pipe; When 2, injecting polyurethane because of compound thermal insulating pipe can not be crooked, the length limited system of thermal insulation pipe.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can make equally distributed compound thermal insulating pipe in the cavity of thermal insulating material between inner and outer pipes.
The technological scheme that technical solution problem of the present invention is adopted is: this includes manages and is enclosed within the outer outer tube of said interior pipe in one; Be provided with a plurality of supports between pipe and the said outer tube in said; A plurality of said supports are separated into a plurality of chambers with the cavity between pipe in said and the said interior pipe, are filled with thermal insulating material in each said chamber.
In the above-mentioned compound thermal insulating pipe technological scheme, technological scheme can also be more specifically: said support is evenly distributed between said interior pipe and the said outer tube; Said thermal insulating material is a polyurethane.
Owing to adopted technique scheme; The present invention compared with prior art has following beneficial effect: 1, because outer tube or interior pipe adopt the fixed support of straight forming; The coaxality of pipe and outer tube in guaranteeing during sleeve pipe; Guarantee the even of insulation layer thickness, improved the thermal insulation property of compound thermal insulating pipe; Because of there being support to fix between the inner and outer pipes, length is unrestricted when 2, injecting polyurethane.

Embodiment
Below in conjunction with accompanying drawing embodiment the present invention is made further detailed description:
The outer outer tube 1 of pipe 3 in the embodiment's 1 who shows like Fig. 1 compound thermal insulating pipe includes pipe 3 in and is enclosed within radially inwardly is distributed with 3 supports at the internal surface of outer tube 1, and the inner diameter of a circle of 3 supports is littler 1 millimeter than the external diameter of interior pipe 3, and is as shown in Figure 2; The length of support is identical with the complex heat-preservation length of tube; Cavity between interior pipe 3 and the outer tube 1 is separated into 3 chambers by 3 supports; All be filled with polyurethane 2 in each chamber.When pipe 3 is outer in outer tube 1 is enclosed within, because the inner circle of the support of outer tube 1 is less than the cylindrical of interior pipe 3, the support of outer tube 1 and interior pipe 3 interference fit, the support of outer tube 1 is fixing with interior pipe 3, and pipe 3 and the coaxality of outer tube 1 are in the scope of stipulating in guaranteeing; Guarantee filling the polyurethane heat-insulation layer thickness evenly, improve the thermal insulation property of compound thermal insulating pipe.
The outer outer tube 1 of pipe 3 in the embodiment's 2 who shows like Fig. 3 compound thermal insulating pipe includes pipe 3 in and is enclosed within radially inwardly is distributed with 3 supports at the outer surface of interior pipe 3, and the outer end diameter of a circle of 3 supports is bigger 1 millimeter than the internal diameter of outer tube 1, and is as shown in Figure 4; The length of support is identical with the complex heat-preservation length of tube; Cavity between outer tube 1 and the interior pipe 3 is separated into 3 chambers by 3 supports, all is filled with polyurethane 2 in each chamber.When pipe 3 is outer in outer tube 1 is enclosed within, because the outer end circle of the support of interior pipe 3 is greater than the interior circle of outer tube 1, the support of interior pipe 3 and outer tube 1 interference fit, the support of interior pipe 3 is fixing with outer tube 1, and the coaxality of pipe 3 and outer tube 1 is in the scope of stipulating in guaranteeing; Guarantee filling the polyurethane heat-insulation layer thickness evenly, improve the thermal insulation property of compound thermal insulating pipe.
Claims (3)
1. compound thermal insulating pipe; Include and manage and be enclosed within the outer outer tube of said interior pipe in one; It is characterized in that: be provided with a plurality of supports between pipe and the said outer tube in said; A plurality of said supports are separated into a plurality of chambers with the cavity between pipe in said and the said interior pipe, are filled with thermal insulating material in each said chamber.
2. the thermal insulation pipe that meets according to claim 1 is characterized in that: said support is evenly distributed between said interior pipe and the said outer tube.
