Abstract
The utility model discloses a foamed thermal insulation pipe consisting of an outer pipe, an inner pipe, and a thermal insulation layer which fills the space between the outer pipe and the inner pipe, wherein the outer pipe and the inner pipe share the same axis center. Because the thermal insulation layer is sandwiched between the outer pipe and the inner pipe, the thermal insulation layer in sealed and cannot be damaged easily. Therefore the foamed thermal insulation pipe is advantaged by prolonged service life of the pipeline, ideal thermal insulation effects, and convenient installation construction.
Description
Technical field
The utility model relates to the plumbing pipe in a kind of plumbing, particularly a kind of insulation pipe.
Background technique
Thermal insulation pipe is the pipeline a kind of commonly used in the plumbing, existing thermal insulation pipe is by realizing in pipeline outer wrapping heat-preservation cotton, in construction, laid first pipeline, then manually in pipeline outer wrapping heat-preservation cotton, the work progress of this pipeline comparatively bothers, particularly heat-preservation cotton is exposed outside, cruelly leak under the environment of exposing to the weather for a long time, heat-preservation cotton is aging or destroyed easily, causes the effect decline that is incubated or does not have insulation effect.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of heat insulation effect desirable, foam insulated pipes easy for installation.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of foam insulated pipes is made of outer tube and the inner tube of concentric and the thermal insulation layer that is filled between described outer tube and the inner tube.
As further improvement of the utility model, described outer tube is made by the PVC material.
Described inner tube is made by the PPR material.
Described thermal insulation layer is the Pu material.
The thickness of described thermal insulation layer is more than the 15mm, and 100 meters temperature drops guarantee in 1 ℃.
The beneficial effects of the utility model are: thermal insulation layer of the present utility model is clipped between outer tube and the inner tube, and thermal insulation layer is sealed, and is not easy destroyedly, has prolonged working life of pipeline, and heat insulation effect is desirable, and installation is convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is sectional view of the present utility model.
Embodiment
With reference to Fig. 1, a kind of foam insulated pipes is made of outer tube RA and the inner tube RB of concentric and the thermal insulation layer RO that is filled between described outer tube RA and the inner tube RB.
In the present embodiment, described outer tube RA is by the PVC(PVC＝polyvinyl chloride) material makes, described inner tube RB is by the PPR(polypropylene) material makes, and described thermal insulation layer RO is Pu(polyurethane) material.
The thickness of thermal insulation layer determines the effect of insulation, and in the present embodiment, the thickness of described thermal insulation layer RO is more than the 15mm, and such 100 meters temperature drops guarantee in 1 ℃.
Because thermal insulation layer of the present utility model is clipped between outer tube and the inner tube, thermal insulation layer is sealed, and is not easy destroyedly, has prolonged working life of pipeline, and heat insulation effect is desirable, and installation is convenient.
Claims (5)
1. foam insulated pipes, it is characterized in that it by outer tube (RA) and the inner tube (RB) of concentric and be filled in described outer tube (RA) and inner tube (RB) between thermal insulation layer (RO) consist of.
