Abstract
The utility model discloses a preheating direct-buried type hot water heat insulating pipe, which comprises a pipe body. A polyurethane heat insulating layer and a high-density polyethylene outer protection pipe are sequentially arranged outside the pipe body from inside out in a covering way. An ultraviolet protection pipe or an ultraviolet protection coating layer is arranged on the high-density polyethylene outer protection pipe in a covering and sheathing way. The utility model has the advantages that the outdoor storage duration of the heat insulating pipe can be effectively prolonged, the quality problem is prevented and the normal use of the insulating pipe is ensured.
Description
Technical field
The utility model relates to the heating thermal insulation pipe of a kind of heat distribution pipe network, particularly preheating directly buried type hot water thermal insulating pipe.
Background technique
Heat distribution pipe network need use a large amount of thermal insulation pipes to carry out delivery, and at present, people's research and development energy mostly concentrates on the thermal insulation property of endeavouring to improve thermal insulation pipe, reduces heat loss, improves heating effect.But thermal insulation pipe is after making well, sometimes can not be used to carry out the installation operation of heat distribution pipe network immediately, usually need to leave on the place to wait for a period of time, during this period, ultraviolet ray in the sunlight often causes harmful effect to thermal insulation pipe, cause product quality problem, reduce the thermal insulation property of thermal insulation pipe.
The model utility content
The purpose of this utility model is to provide a kind of preheating directly buried type hot water thermal insulating pipe, and it is simple in structure, is easy to manufacture, and is cheap, can effectively reduce and reduce the influence of ultraviolet ray to the thermal insulation pipe body, prolongs depositing and service time of thermal insulation pipe.
The purpose of this utility model is achieved in that a kind of preheating directly buried type hot water thermal insulating pipe, comprise body, coated successively from inside to outside outward polyurethane insulation coating and the outer pillar of high density polyethylene (HDPE) of being provided with of body, coated again suit is being provided with ultraviolet protection pipe or ultraviolet protection coating on the pillar outside high density polyethylene (HDPE).
The utility model is by being provided with protecting tube or ultraviolet protection coating on the pillar outside, can effectively reduce and reduce the influence of ultraviolet ray to the thermal insulation pipe body, can effectively prolong the outdoor resting period of thermal insulation pipe, prevent quality problems, guarantee that thermal insulation pipe can normally use.The utility model is simple in structure, and low cost of manufacture is easy to promote.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a perspective view of the present utility model.
Embodiment
A kind of preheating directly buried type hot water thermal insulating pipe, as shown in drawings, comprise body 2, body 2 outer coated successively from inside to outside polyurethane insulation coating 1 and the outer pillars 3 of high density polyethylene (HDPE) of being provided with, coated again suit is being provided with ultraviolet protection pipe or ultraviolet protection coating 4 on the pillar 3 outside high density polyethylene (HDPE).
The thickness of ultraviolet protection pipe or ultraviolet protection coating 4 is 0.1-1mm.
By on the pillar 3 protecting tube or ultraviolet protection coating 4 being set outside, can effectively reduce and reduce the externally influence of pillar 3 of ultraviolet ray, can effectively prolong the outdoor resting period of thermal insulation pipe, prevent quality problems, guarantee that thermal insulation pipe can normally use.
Claims (2)
1. preheating directly buried type hot water thermal insulating pipe, comprise body, coated successively from inside to outside outward polyurethane insulation coating and the outer pillar of high density polyethylene (HDPE) of being provided with of body, it is characterized in that: coated again suit is being provided with ultraviolet protection pipe or ultraviolet protection coating on the pillar outside high density polyethylene (HDPE).
2. preheating directly buried type hot water thermal insulating pipe according to claim 1, it is characterized in that: the thickness of ultraviolet protection coating is 0.1-1mm.
