Abstract
The utility model provides a kind of multilayer corrugated flexible pipe, including outer layer and internal layer;The internal layer is arranged on and the pipeline that guiding medium flows through is constituted in outer layer;The internal layer includes the nested inner and outer tubes set, and the inner and outer tubes are alongst continuously distributed wave structure.The utility model provides a kind of multilayer corrugated flexible pipe, and the compliance of product is improved on the premise of properties of product are met, so as to avoid body from occurring compared with the not smooth phenomenon of water flowing when being bent under small-bend radius.
Description
Technical field
The utility model is related to a kind of flexible pipe, more particularly to a kind of corrugated flexible hose.
Background technology
The use of corrugated flexible hose in daily life is very frequent, because it possesses certain telescopic effect, in order to protect
Retractility is demonstrate,proved, the toughness of corrugated flexible hose is stronger, and just can guarantee that can still possess good telescopicing performance after long-term use.
But corrugated flexible hose generally requires to be bent, therefore again need to have certain when in use nor use as straight tube
Flexibility, so just can guarantee that corrugated flexible hose after bending, additionally it is possible to normal boot medium flow out.Therefore, toughness and it is flexible just
The requirement point of a relative contradiction is constituted, existing corrugated flexible hose tends not to take into account toughness and flexibility.
Utility model content
Technical problem underlying to be solved in the utility model is to provide a kind of multilayer corrugated flexible pipe, is meeting properties of product
On the premise of improve the compliance of product so that the not smooth phenomenon of water flowing when avoiding the body from bending occurs.
In order to solve above-mentioned technical problem, the utility model provides a kind of multilayer corrugated flexible pipe, including outer layer and interior
Layer;The internal layer is arranged on and the pipeline that guiding medium flows through is constituted in outer layer;The internal layer includes the nested inner tube set and outer
Pipe, the inner and outer tubes are alongst continuously distributed wave structure.
In a preferred embodiment:The inner tube flexibility of the internal layer is more than inner tube more than the toughness of outer tube, outer tube.
In a preferred embodiment:Said inner tube is cross-linked to form nested structure with PE at high temperature with outer tube for PEX.
In a preferred embodiment:Said inner tube is cross-linked to form nested structure with PE at high temperature with outer tube for silica gel.
In a preferred embodiment:The outer layer is the outer woven plastics silk layer or metal wire layer being wrapped in outside outer tube.
In a preferred embodiment:The outer woven plastics silk is compiled using the braiding of monofilament multiply plastic wire or concatemer flat filament
Knit.
In a preferred embodiment:Section of the wave structure along inner and outer tubes length direction is trapezoidal.
Compared to prior art, the technical solution of the utility model possesses following beneficial effect:
1. a kind of multilayer corrugated flexible pipe that the utility model is provided, the internal layer of flexible pipe can be by combination of different materials
The compliance of product is improved on the premise of meeting properties of product, so as to avoid body compared with water flowing when being bent under small-bend radius
Not smooth phenomenon occurs.
2. a kind of multilayer corrugated flexible pipe that the utility model is provided, the outer layer of flexible pipe is the outer braiding modeling being wrapped in outside outer tube
Expect silk layer or metal wire layer;Its China and foreign countries' woven plastics layer can use the outer weaving of concatermer flat filament, both improve production
Efficiency also prevented the jump silk phenomenon that common silk is produced in braiding production, improve the outward appearance of product, tension and measuring body
Performance.
Brief description of the drawings
Fig. 1 is the structure sectional view of the utility model preferred embodiment.
Embodiment
Hereafter the utility model is described further by the drawings and specific embodiments.
With reference to Fig. 1, a kind of multilayer corrugated flexible pipe, including outer layer 1 and internal layer 2;The internal layer 1 is arranged on composition in outer layer 2
The pipeline that guiding medium flows through;The internal layer 2 includes the nested inner tube 11 set and outer tube 12, the inner tube 11 and outer tube 12 along
Length direction is continuously distributed to be had in wave structure, the present embodiment, and the section of the wave structure alongst is ladder
Shape.
The flexible toughness more than outer tube 12, outer tube 12 of inner tube 11 of the internal layer 1 is more than inner tube 11.In order to realize that this is imitated
Really, the material selection PEX or silica gel of inner tube, the material selection PE of outer tube.So the material of inner tube 11 and inner tube 12 is placed in
Crosslinking just can form nested undulatory structure with after extruding under high temperature.
Because the toughness of outer tube 12 is preferable, the flexibility of inner tube 11 is preferable, it therefore meets being improved on the premise of properties of product
The compliance of product, so as to avoid body from occurring compared with the not smooth phenomenon of water flowing when being bent under small-bend radius.
The outer layer 2 is the outer woven plastics silk layer being wrapped in outside outer tube 12, and it uses concatemer flat filament technique to be compiled
Knit.Both improve the efficiency of production or prevented the jump silk phenomenon that common silk is produced in braiding production, improve the outer of product
See and performance.
Described outer woven plastics silk layer can also be using the braiding of monofilament multiply plastic wire, and the routine for belonging to prior art is replaced
Change, repeat no more.
It is pointed out that the outer layer 2 can also be the metal wire layer being wrapped in outside outer tube 12.
The above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is defined by scope of the claims.
