Life, the serious application space for constraining PVC tubing.
Utility model content
The purpose of this utility model is in view of the above shortcomings of the prior art, to provide a kind of PVC with heat-insulating property
Pipe, the tubing have heat-preservation cold-resistance performance, can meet the use needs of low temperature environment.
To reach above-mentioned technique effect, technical solution is as follows used by the utility model：
The utility model has the pvc pipe of heat-insulating property, and including outer tube, inner tube and insulating layer, outer tube is placed on outside inner tube
Portion, insulating layer are arranged between outer tube and inner tube, and the insulating layer includes the first insulating layer and the second insulating layer, the first insulating layer
It is placed on outside the second insulating layer, second insulating layer includes several PET honeycomb core pipes, and PET honeycombs core pipe is along inner tube
Excircle uniform intervals are set, and polyurethane filled layer is provided between adjacent two PET honeycomb core pipes.
As the preferred embodiment of the utility model, first insulating layer includes alumina silicate fibre layer, in alumina silicate fibre
The inner and outer wall of layer is both provided with net metal silk layer.
As the preferred embodiment of the utility model, reinforcing rib is provided on the tube wall of inner tube, the reinforcing rib is along inner tube
Length direction set.
As the preferred embodiment of the utility model, the section of the reinforcing rib is triangle, trapezoidal, rectangle or arc.
As the preferred embodiment of the utility model, cvd diamond coating is coated in reinforcing rib outer surface.
As the preferred embodiment of the utility model, the outer tube and inner tube are PVC material pipe.
The beneficial effects of the utility model are：Structure novel has heat-preservation cold-resistance performance, and tubing is prevented to be subject to extraneous low gas
The influence of temperature can meet the use needs of low temperature environment, while light weight, convenience in transport.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the utility model structure diagram.
Fig. 2 is the A portions enlarged drawing of Fig. 1.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making the creative labor
All other embodiments obtained shall fall within the protection scope of the present invention.
As shown in drawings, the utility model has the pvc pipe of heat-insulating property, including outer tube 1, inner tube 2 and insulating layer, outer tube
1 is placed on outside inner tube 2, and insulating layer is arranged between outer tube 1 and inner tube 2.It is described by setting outer tube, inner tube and insulating layer
Outer tube and inner tube are PVC material pipe, and insulating layer can improve the heat preservation anti-freezing property of this pipe, so as to improve the service life of pvc pipe
And adaptability.
The insulating layer includes the first insulating layer and the second insulating layer, and the first insulating layer is placed on outside the second insulating layer.
On the one hand first insulating layer plays just effect insulation effect, fire protecting performance and the tubing that on the other hand can increase tubing strong
Degree extends the service life of tubing.First insulating layer include alumina silicate fibre layer 5, alumina silicate fibre layer 5 inner wall and
Outer wall is both provided with net metal silk layer 6.Alumina silicate fibre layer is a kind of New type of light refractory material, which has unit weight
Gently, high temperature resistant, thermal stability are good, and it is excellent that pyroconductivity is low, thermal capacitance is small, resistance to mechanical is vibrated, expanded by heating is small, heat-proof quality is good etc.
Point has good heat preservation and fire protecting performance.Net metal silk layer 6 can the effective intensity for improving tubing, and light weight.
Second insulating layer includes several PET honeycombs core pipes 3, between the excircle of PET honeycombs core pipe 3 along inner tube is uniform
Every setting, polyurethane filled layer 4 is provided between adjacent two PET honeycomb core pipes.PET honeycombs core pipe 3 has light weight, intensity
The features such as big, and the excellent thermal insulation performance of honeycomb duct, can improve heat-insulating property more in the case where crossing pipe workpiece quality do not increase.
To further improve the intensity of tubing, reinforcing rib 7 is provided on the tube wall of inner tube 2, the reinforcing rib 7 is along inner tube
Length direction set.By setting reinforcing rib, on the one hand play the role of improving tubing intensity, on the other hand also act as water conservancy diversion
Effect.The section of the reinforcing rib 7 is preferably triangle, trapezoidal, rectangle or arc.
In addition, to improve the intensity of reinforcing rib, cvd diamond coating is coated in 7 outer surface of reinforcing rib.Cvd diamond
On the one hand coating can improve the intensity of reinforcing rib, on the other hand can reduce reinforcing rib with crossing the frictional force of water in pipe, prevent water
Reduced velocity flow.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modifications, equivalent replacements and improvements are made should be included in the utility model
Protection domain within.
