Abstract

The utility model provides a high temperature resistant polyurethane thermal insulation pipe way, including work pipe, parcel insulating layer (aerogel) and the aluminium foil reflection cloth of package on the insulating layer on the work pipe, the polyurethane insulation layer between the outer wall of aluminium foil reflection cloth and the inner wall of outer pillar, outer pillar adopts high strength PE pipe shell. Set up decomposition and carbonization that the insulating layer had avoided polyurethane to lead to owing to high temperature. When the insulating layer adopted the aerogel, the coefficient of heat conductivity of aerogel was less than polyurethane coefficient of heat conductivity, has reduced heat dissipation. After the heat of work pipe passed through aerogel layer, temperature control was protecting polyurethane below 140 DEG C. Improve polyurethane thermal insulation pipe's thermal insulation performance, increased the heat utilization of pipe network, reduce heat loss.

Description

A kind of high temperature resistant polyurethane heat-preserving pipeline
Technical field
This utility model belongs to hot duct field, a kind of heat distribution pipe network plumbing installation.
Background technology
The structure of the widely used polyurethane heat-preserving pipeline of heat distribution pipe network is at present: instrumentation tubes;Plastic stent;Polyurethane insulation coating;High density polyethylene pipe.The common structure of steam heat preserving pipeline is: working steel tube;Thermal insulation layer;Metallic reflective coating;Working steel tube;Anticorrosive coat.The long-term heatproof of polyurethane is in T≤140 DEG C, and when temperature is more than this limit, polyurethane interiorization compound will decompose or carbonization, have impact on the heat insulation effect of polyurethane, and it is high to there is heat conductivity, and energy rate of scattering and disappearing is high, and the problem such as insulation life is short.
Summary of the invention
In view of the defect of prior art, this utility model provides a kind of high temperature resistant polyurethane heat-preserving pipeline, and it is that direct burried polyurethane insulating tube is improved by the structure combining jet chimney, increases thermal insulation layer and improves heat insulation effect, reduce heat-energy losses on the basis of original.
For reaching above-mentioned purpose, the technical scheme that this utility model provides is a kind of high temperature resistant polyurethane heat-preserving pipeline, and it includes instrumentation tubes, thermal insulation layer, aluminium foil layer of cloth, some supports, polyurethane insulation coating and outer pillar;Instrumentation tubes outer wrapping thermal insulation layer, thermal insulation layer outer wrapping aluminium foil layer of cloth, aluminium foil layer of cloth outer wrapping polyurethane insulation coating, the outer pillar of polyurethane insulation coating outer wrapping, some supports are set inside polyurethane insulation coating.
Preferably thermal insulation layer is aerogel layer.
Outer pillar is high strength polyethylene pipe shell.
Preferably instrumentation tubes is metal tube.
Described support is particular design support, it includes bracing frame, fixed via, alarming line through hole and filler through hole, described fixed via is arranged on two sides of bracing frame, described alarming line through hole and filler through hole are separately positioned on two other side of bracing frame, and alarming line through hole is arranged on filler through hole top, bottom support frame as described above, it is provided with groove.Described support arranges four, uniformly and is two-by-two symmetrically distributed in inside polyurethane insulation coating.
The beneficial effects of the utility model: the long-term heatproof of polyurethane is in T≤140 DEG C, and when temperature is more than this limit, polyurethane interiorization compound will decompose or carbonization, have impact on the heat insulation effect of polyurethane.When arranging thermal insulation layer, the temperature of thermal insulation layer and polyurethane interface remains at less than 140 DEG C, it is to avoid decomposition that polyurethane causes due to high temperature and carbonization.Thermal insulation layer is exotic material aeroge, and heat resisting temperature is more than 1000 DEG C of high insulating effect.When thermal insulation layer uses aeroge, the heat conductivity of aeroge is less than polyurethane heat conductivity, reduces radiation loss.The heat of instrumentation tubes is by after aerogel layer, and temperature controls to protect polyurethane below 140 DEG C.Improve the heat-insulating property of polyurethane thermal pipe, add the heat energy utilization of pipe network, reduce heat loss.
Arrange distinctive New-support to play a supportive role, it is easy to polyurethane foam, need to tie up well with steel band or iron wire string before polyurethane foam on steel pipe, support outer pillar shell, ensure the support support that polyurethane insulation coating is concentric, support the identical support support of outer pillar shell guarantee insulation layer thickness for heat distribution pipeline, the consistency of thickness supporting guarantee polyurethane insulation coating between polyurethane pipe interior steel pipe and outside shell, make whole outer pillar concentric with steel pipe, this support uses simple, convenient, low cost, solve the eccentricity issues in foaming work, this utility model is because New-support plays a supportive role and makes heat-insulation layer more uniform, there is more preferable heat insulation effect.
