Layer, to enhance the thermal insulation property of heat-preservation plastic pipeline；
Jacket ducts, medium pipeline are usually made of polythene material resistant to high temperature.
As a preferred embodiment of the above technical solution, the jacket ducts and the medium pipeline are bellows.
In the prior art, pipeline needs the part turned round usually to be realized by three-way connection, and the junction of three-way connection
The often weakness of heat insulation effect, which reduce the integral heat insulation effects of pipeline, and increase the production cost of pipeline.
As a preferred embodiment of the above technical solution, first fiber insulation layer be fibrous material it is woven made of cover
Pipe.
The first insulation fibre layer worked out, each weaving unit interlock place in the presence of more apparent air layer, energy
Enough enhance the integral heat insulation performance of pipeline.
And in bending, the medium pipeline and filling heat insulating wall in knee are moved both with respect to the first fiber insulation layer, are made
Pipeline still maintains preferable intensity and structural stability in bending section, and knee is released by material bring stress.
As a preferred embodiment of the above technical solution, first fiber insulation layer includes superimposed by fibrous material two layers
Casing made of woven.
Two layers of woven manufactured casing is superimposed, in knee, the opposite fortune of medium pipeline and filling heat insulating wall
Dynamic to be respectively acting on the first fiber insulation layer adjacent thereto, two layers of casing also can be movable relatively, relative to one layer of structure
The first fiber insulation layer for, the structural stability in knee is more preferable.
As a preferred embodiment of the above technical solution, the insulation portion also includes be set to the jacket ducts internal layer second
Fiber insulation layer.
As a preferred embodiment of the above technical solution, second fiber insulation layer be fibrous material it is woven made of cover
Pipe.
As a preferred embodiment of the above technical solution, second fiber insulation layer includes superimposed by fibrous material two layers
Casing made of woven.
The setting reason and principle of second fiber insulation layer are the same as the first fiber insulation layer.
As a preferred embodiment of the above technical solution, the quantity of the medium pipeline is two, and the setting at interval is in the sheath
In pipeline.
As a preferred embodiment of the above technical solution, the filling heat insulating wall is polyurethane material insulating layer flexible.
As a preferred embodiment of the above technical solution, the internal diameter of the jacket ducts is between 75 ~ 225mm, correspondingly, being given an account of
The outer diameter of matter pipeline is between 25 ~ 160mm.
In conclusion the utility model has the following beneficial effects:
The application provides a kind of central heating prefabricated thermal insulation plastic conduit and compares for the hot water delivery of central heating
For the thermo-insulating pipe line of existing polyethylene collocation polyurethane, thermal insulation property can promote 5% ~ 11.7%, be more adaptive to cash
The actual environment of energy shortage；
And by being directly bent instead of three-port structure, the structure in knee is more stable in its knee, also further protects
Thermal insulation property is demonstrate,proved.
