Abstract
The utility model discloses a prefabricated polyurethane foam insulating pipe for trenches, which comprises a pipe body. A high-density polyethylene outer protective pipe is coated on the pipe body, a polyurethane foam insulating layer is filled between the pipe body and the high-density polyethylene outer protective pipe, and a warning line is arranged inside the polyurethane foam insulating layer. The pipe body, the polyurethane foam insulating layer and the high-density polyethylene outer protective pipe form an integrated structure in the prefabricated polyurethane foam insulating pipe for the trenches. The prefabricated polyurethane foam insulating pipe for the trenches is capable of reducing the heat loss of pipe network effectively, excellent in water-proof property, long in service life and convenient to construct.
Description
Technical field
The utility model relates to a kind of thermal insulation pipe, relates in particular to a kind of trench with prefabricated polyurethane foam insulation pipe.
Background technique
Trench is widely used in the central heat supply field with thermal insulation pipe, and its thermal insulating material that adopts mostly is rock wool, glass wool, perlite watt etc.Adopt the shortcoming of this type of thermal insulating material to be that thermal loss is big, water-proof performance is poor, the life-span is shorter.
The model utility content
The utility model is at the drawback of prior art, provides a kind of trench with prefabricated polyurethane foam insulation pipe.
Trench described in the utility model is with prefabricated polyurethane foam insulation pipe, comprise body, described body is coated with the outer pillar of high density polyethylene (HDPE), is filled with polyurethane foam insulation layer between the outer pillar of described body and high density polyethylene (HDPE), is provided with alarming line in the described polyurethane foam insulation layer.
Trench described in the utility model is with in the prefabricated polyurethane foam insulation pipe, and body, polyurethane foam insulation layer, the outer pillar of high density polyethylene (HDPE) are formed monolithic construction, can effectively reduce the pipe network thermal loss, and water-proof performance are superior, the life-span long, easy construction.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of trench described in the utility model with prefabricated polyurethane foam insulation pipe.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1, trench described in the utility model is with prefabricated polyurethane foam insulation pipe, comprise body 1, described body 1 is coated with the outer pillar 3 of high density polyethylene (HDPE), be filled with polyurethane foam insulation layer 2 between the outer pillar 3 of described body 1 and high density polyethylene (HDPE), be provided with alarming line 4 in the described polyurethane foam insulation layer 2.
Trench described in the utility model to this special environment of trench, has been brought into play the excellent properties of polyurethane foam and high density polyethylene (HDPE) with prefabricated polyurethane foam insulation bobbin to greatest extent, makes the thermal insulation pipe performance of trench laying obtain very big lifting.
In actual course of working, can be by outer surface of tube body being carried out Shot Blasting and the outer pillar of high density polyethylene (HDPE) being carried out the internal surface corona treatment, to guarantee that trench with the outer Trinitarian integrity structure of pillar of body, polyurethane foam insulation layer and the high density polyethylene (HDPE) of prefabricated polyurethane foam insulation pipe, has strengthened the shear strength between the three.And the seam quantity of thermal insulation pipe is far fewer than the thermal insulation pipe of conventional construction, makes the thermal loss that has reduced pipe network in the practical application effectively.
In the utility model, adopt the polyurethane foam insulation layer of fluorin environment protection foaming system production can guarantee that thermal insulation pipe service life under 140 ℃ of temperature reached more than 30 years, and instantaneous peak value temperature that can be anti-150 ℃ and do not have carbonization and distortion.The water vapour permeability of the outer pillar of described high density polyethylene (HDPE) is low, and good sealing effect can tolerate 70 degrees centigrade ambient temperature and keep key property; Can bear the abominable working condition that unusual water inlet is soaked in the trench to a certain extent, keep original performance substantially.And polyurethane heat insulation material can keep its performance in the working life in 30 years.This polyurethane insulation coating foam adopts the fluorine-free and environment-friendly foaming system, and polyurethane insulation coating foam at high temperature volatile matter does not seldom influence the environment in the trench.
Trench described in the utility model reduces with prefabricated polyurethane foam insulation tube field easy construction, construction amount, can shorten the heat preservation construction cycle significantly.Simultaneously, can reduce the workload of operation maintenance, Security is improved.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
Claims (1)
1. a trench is with prefabricated polyurethane foam insulation pipe, comprise body, it is characterized in that described body is coated with the outer pillar of high density polyethylene (HDPE), be filled with polyurethane foam insulation layer between the outer pillar of described body and high density polyethylene (HDPE), be provided with alarming line in the described polyurethane foam insulation layer.
