Description
Technical field
The present invention relates to plastic conduit technical field, specially a kind of frost-cracking-preventing plastic conduit.
Background technology
Plastic tube is usually using plastics as matrix, is formed in tuber through extrusion process, its use range is extensive, still
Plastic tube easy bursting by freezing under the relatively low use environment of temperature, and easy aging, have had a strong impact on normal use, have greatly reduced
Service life, while freezing prevention tubing of the prior art, mostly simply using simple antifreeze sponge, therefore when antifreeze sponge goes out
When existing damaged, cold air is directly attacked in the outer surface of pipeline, causes pipeline by bursting by freezing, and the outer surface of pipeline be it is smooth, because
The contact area of the outer surface of this antifreeze sponge and pipeline is limited, therefore antifreezing effect is poor.
The content of the invention
It is an object of the invention to provide a kind of frost-cracking-preventing plastic conduit, to solve the pipeline proposed in above-mentioned background technology
The problems such as being unable to frost-cracking-preventing and influenceing normal use and reduce service life.
To achieve the above object, the present invention provides following technical scheme：A kind of frost-cracking-preventing plastic conduit, including pipeline sheet
Body, the outer wall of the pipeline body are enclosed with antifreeze spongy layer, and the inwall of the antifreeze spongy layer is provided with salient point, described antifreeze
The outer wall of spongy layer is enclosed with fibrous layer, and the fibrous layer includes glass layer, and the bottom of the glass layer is provided with
Polyethylene fiber layer, the outer wall of the fibrous layer are enclosed with heat-insulation layer, and the outer wall of the heat-insulation layer is enclosed with protection shell.
Preferably, the heat-insulation layer is phenolic foam layer.
Preferably, the antifreeze spongy layer is rubber foam sponge pipe.
Preferably, the pipeline body is plastic conduit.
Compared with prior art, the beneficial effects of the invention are as follows：Effectively the temperature inside pipeline is entered by heat-insulation layer
Row insulation is not in too cold during winter and causes the phenomenon of bursting by freezing, and further the temperature in pipeline is carried out by fibrous layer
Insulation, when effectively preventing cold weather by antifreeze spongy layer, current condensation causes the bursting by freezing of pipeline in inner-walls of duct,
Antifreeze sponge material does not absorb water used by this practicality, not condensation, and material completely cuts off completely with steam.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the antifreeze spongy layer structural representation of the present invention；
Fig. 3 is fiber layer structure schematic diagram of the present invention.
In figure：1 pipeline body, 2 antifreeze spongy layers, 21 salient points, 3 fibrous layers, 31 glass layers, 32 polyethylene fibres
Layer, 4 heat-insulation layers, 5 protection shells.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of frost-cracking-preventing plastic conduit, including pipeline body 1,
The outer wall of the pipeline body 1 is enclosed with antifreeze spongy layer 2, and the inwall of the antifreeze spongy layer 2 is provided with salient point 21, described anti-
The outer wall for freezing spongy layer 2 is enclosed with fibrous layer 3, and the fibrous layer 3 includes glass layer 31, the bottom of the glass layer 31
End is provided with polyethylene fiber layer 32, and the outer wall of the fibrous layer 3 is enclosed with heat-insulation layer 4, and the outer wall of the heat-insulation layer 4 is enclosed with
Protect shell 5.
Wherein, the heat-insulation layer 4 is phenolic foam layer, has the features such as processing easy-formation, preferable durability, institute
It is rubber foam sponge pipe to state antifreeze spongy layer 2, and thermal conductivity factor is low, and material completely cuts off completely with steam, do not absorb water, not condensation, make
With long lifespan, the pipeline body 1 is plastic conduit.
During installation, the rubber foam sponge pipe sleeve of antifreeze spongy layer 2 is connected on to the outer wall of pipeline body 1, its antifreeze sponge
The outer wall of layer 2 is provided with salient point 21, increases its contact area with pipeline body 1, its outer layer is provided with fibrous layer 3 and heat-insulation layer
4, double-layer heat insulation so that the bursting by freezing of pipeline body 1 can be effectively prevented in severe cold air weather, in liquid passes through conduit sheet
During body 1, because the rubber foam sponge pipe in antifreeze spongy layer 2 does not absorb water, not condensation, it is therefore prevented that liquid be bonded at inner-walls of duct and
Generation bursting by freezing phenomenon.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
