Description
Technical field
The present invention relates to a kind of heating system pipeline used, be specifically related to a kind of multilayer heating pipeline.
Background technique
Heating is carried out by hot-water heating in the winter time in increasing area now, and in the winter time heating time sometimes need in certain distance, to transmit hot water at outdoor application pipeline, outdoor temperature is lower in the winter time, can be lost the heat of significant proportion by pipeline transmission hot water, this can cause the waste of the energy significantly; And pipeline in outdoor temperature lower than as easy as rolling off a log by bursting by freezing during zero degree, once bursting by freezing repairing get up to bother very much.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide multilayer heating pipeline.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of multilayer heating pipeline, its water passage hole from pipeline center comprises 4 layers of body (1) from inside to outside: Anti-crack layer (2), and described Anti-crack layer is made up of elastic material; Screen layer (3), described screen layer is made up of liquid-crystalline polymer; Thermal insulation layer (4), described thermal insulation layer is made up of silica-based thermal insulating material; Outer shell layer (5), described outer shell layer is by be cross-linked or heat-resisting polymer is made.
Further, the thickness of described Anti-crack layer can calculate according to the volume of body, shape.
Further, described screen layer is made up of liquid-crystalline polymer, and wherein said liquid-crystalline polymer can comprise polar polymer and non-polar polymer.
Further, described thermal insulation layer is made up of silica-based thermal insulating material, and wherein said silica-based thermal insulating material can be made up of silicone based crystal and tackiness agent.
Further, described outer shell layer is by be cross-linked or heat-resisting polymer is made, wherein said crosslinked or heat-resisting polymer can be polyethylene or polybutylene is made.
Usefulness of the present invention is: due to the existence of pipeline Elastic layer, significantly reduces the probability of pipeline breaking, and also comprises thermal insulation layer in pipeline, and the heat insulating ability of pipeline is also greatly improved.After using the present invention, not only increase the utilization ratio of the energy, and decrease the expense of heating pipeline later period maintenance, saved cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of multilayer heating pipeline of the present invention;
The implication of reference character in figure:
1-water passage hole, 2-Anti-crack layer, 3-screen layer, 4-thermal insulation layer, 5-outer shell layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
With reference to Fig. 1, a kind of multilayer heating pipeline of the present invention, its water passage hole from pipeline center comprises 4 layers of body (1) from inside to outside: Anti-crack layer (2), screen layer (3), thermal insulation layer (4) and outer shell layer (5).
When the external temperature of pipeline is lower than zero degree, the water in water passage hole can freeze, and understands volumetric expansion and then cause the body of heating pipeline to break after water freezing.And the Anti-crack layer (2) in multilayer heating pipeline in the present invention is formally arranged to solve the problem, described Anti-crack layer can be made up of elastic material, and the thickness of Anti-crack layer can be calculated by the shape of body.Can in calculated water hole by the maximum volume of water, after must being the maximum volume of water, the volume of its maximum swelling after obtaining freeze over that converts and then obtain the thickness of Anti-crack layer, thus avoid body to break most possibly.
In water heating system, because the water temperature flowed in body is higher, the steam that long-term conveying high-temp liquid brings and high temperature are to the life-span reducing body.Screen layer (3) in multilayer heating pipeline in the present invention is formally arranged to solve the problem.Described screen layer is made up of liquid-crystalline polymer, and described liquid-crystalline polymer can be preferably made up of polar polymer and non-polar polymer.
No matter heating pipeline all can lose a certain amount of heat energy in indoor or at outdoor transmissions, in order to reduce the loss of heat energy, in the multilayer heating pipeline in the present invention, be also provided with thermal insulation layer (4) at screen layer outer (3).Described thermal insulation layer is made up of silica-based thermal insulating material, and wherein said silica-based thermal insulating material can be made up of silicone based crystal and tackiness agent.
Outer shell layer (5) is also had at thermal insulation layer outer (4) in multilayer heating pipeline in the present invention.In order to ensure hardness and the corrosion resistance of outer body, described outer shell layer is by be cross-linked or heat-resisting polymer is made, wherein said crosslinked or heat-resisting polymer can be polyethylene or polybutylene is made.
After multilayer heating pipeline in the present invention uses in actual heating system, through running after a while, significantly reduce the probability of pipeline breaking, and the heat insulating ability of pipeline is also greatly improved, while energy saving, also reduce the expense of later period maintenance.
It should be noted that, above-described embodiment does not limit the present invention in any form, the technological scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
