Description
Technical field
Insulating tube technical field is the utility model is related to, specially a kind of wound form polyurethane thermal pipe.
Background technology
For citizen, we are for living, the protection of living environment, economize on resources, are exactly cither indirectly or directly to protect
Natural environment is protected；We destroy inhabitation, living environment, will cither indirectly or directly destroy natural environment.As government
For, the protection of macroscopic view should be conceived to, started with again from microcosmic, mobilized the masses, educate the masses, make environmental protection, save energy
Source turns into the conscious action of citizen.Insulating tube has very important application, insulating tube in saving the energy, reducing thermal loss
It is to do outer protection tube by interior working steel tube, polyurethane, mineral wool heat-insulation layer, polyethylene or steel pipe to form, it is characterized in that：Also include resistance to
High-temperature heat insulation heat-insulation layer, lubricating layer, elastic sealing element.Insulating tube is the abbreviation of insulated piping, insulating tube be used for liquid, gas and
The conveying of other media, in the adiabatic heat-insulation work of the pipelines such as oil, chemical industry, space flight, military affairs, central heating, central air-conditioning, municipal administration
Journey.
Insulating tube of the prior art is difficult to ensure that heat insulation effect, and thermal loss is big, and does not possess heat effect, uncomfortable
Conjunction is promoted the use of.
Utility model content
The purpose of this utility model is to provide a kind of wound form polyurethane thermal pipe, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of wound form polyurethane thermal pipe, including
Internal layer and outer layer, are provided with packed layer between the internal layer and outer layer, the internal layer, packed layer and outer layer are set successively from the inside to the outside
Put, the packed layer includes resistive heater, crosslinked polyethylene foam films and froth bed, the resistive heater, the poly- second of crosslinking
Alkene foam films and froth bed are set gradually from the inside to the outside.
Preferably, the resistive heater is covered in inner layer outer surface using canoe.
Preferably, the internal layer is PVC structure sheafs, and the outer layer is PPR structure sheafs, and the internal layer and outer layer thickness are not
More than 10mm.
Preferably, the integral thickness of the resistive heater, crosslinked polyethylene foam films and froth bed is no more than 30mm.
Preferably, it is fixedly connected between the polyethylene foam film and froth bed by adhesive glue.
Compared with prior art, the beneficial effects of the utility model are：A kind of wound form polyurethane heat-insulation of the utility model
Pipe, structure is novel, easy to operate, and by the packed layer between internal layer and outer layer, resistive heater is wrapped in into internal layer appearance
Face, heated protective effect can be effectively played, the crosslinked polyethylene foam films of outer layer can be effectively heat-insulated and fire-retardant, foam
Layer also has good heat insulation effect, and internal layer is PVC structure sheafs, and outer layer is PPR structure sheafs, good with corrosion resistance, light weight,
The characteristics of stable performance, there is very high practicality, greatly improve a kind of use function of wound form polyurethane thermal pipe
Property, ensure its using effect and utilization benefit, be adapted to be widely popularized.
