Abstract
The utility model belongs to Manifold technology field, more particularly to a kind of spool of resistance to expanded mesh, including tube body, and tube body includes setting gradually the interior layer of PVC, middle layer of PVC and outer layer of PVC of interconnection from inside to outside, and middle layer of PVC is at least provided with two layers of layer of PVC；The utility model has the advantage that：It is not susceptible to be broken when stretching, service life length.
Description
Technical field
The utility model belongs to Manifold technology field, more particularly to a kind of spool of resistance to expanded mesh.
Background technology
Pvc pipe main ingredient is polyvinyl chloride, it is possible to additionally incorporate other compositions to strengthen its heat resistance, toughness, ductility etc.,
PVC hose is because of low manufacture cost, easy processing, the gas being widely used in the every field such as industry, agricultural and liquid it is defeated
Send.At present, existing hose on the market uses individual layer hose mostly, and individual layer hose is easy to wear in use, and anti-
Tearing strength is low；In the case where having pulling force working environment, when longitudinal stretching, is easily broken；And individual layer hose in use, easy
Deformation, service life are short.
Utility model content
The purpose of this utility model is to provide a kind of spool of resistance to expanded mesh.
What the purpose of this utility model was realized in：
The spool of resistance to expanded mesh, including tube body, the tube body include the interior PVC for setting gradually interconnection from inside to outside
Layer, middle layer of PVC and outer layer of PVC, are equipped with a fibre set along tube body axial direction curl between interior layer of PVC and middle layer of PVC
Line is tieed up, some are equipped between middle layer of PVC and outer layer of PVC along the circumferentially spaced length direction of tube body and tube body axial direction
Consistent fiber line, the middle layer of PVC is at least provided with two layers of layer of PVC.
Above-mentioned every fiber line mutually twists to be formed by 10-30 strands of filaments.
Above-mentioned every fiber line mutually twists to be formed by 24 strands of filaments.
Above-mentioned filament is specially 500D-1000D filaments.
The outer surface of above-mentioned outer layer of PVC is circumferentially spaced, and to be provided with some length directions and tube body axially consistent convex
The reinforcing rib risen.
The outer surface of above-mentioned outer layer of PVC is provided with raised reinforcing rib along tube body length direction is spiral.
The thickness of above-mentioned outer layer of PVC is less than the thickness of middle layer of PVC, and the thickness of interior layer of PVC is less than the thickness of middle layer of PVC.
Above-mentioned tube body is by coating machine one-pass molding.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
The wherein inner tube of the utility model is connected with each other using interior layer of PVC, middle layer of PVC and outer layer of PVC and formed, by interior
The fiber line set along tube body axial direction curl is equipped between layer of PVC and middle layer of PVC, reduces tube body linear expansion
Coefficient, improves expansibility resistance energy and load performance, is not susceptible to deform during use；Pass through middle layer of PVC and outer layer of PVC
Between some fiber lines consistent with tube body length direction are set, the tensile property of tube body is improved, during longitudinal stretching
It is not susceptible to be broken, adds service life.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1：

The intensity of tube body 1 can be increased, tube body 1 includes interior layer of PVC 2,3 and of middle layer of PVC for setting gradually interconnection from inside to outside
Outer layer of PVC 4, is equipped with a fiber line 5 set along the axial curl of tube body 1 between interior layer of PVC 2 and middle layer of PVC 3, in
Some are equipped between layer of PVC 3 and outer layer of PVC 4 along 1 circumferentially spaced length direction of tube body and tube body 1 axial one
The fiber line 5 of cause, every fiber line 5 mutually twist to be formed by 10-30 strands of filaments, it is preferred that every in the utility model
Fiber line 5 mutually twists to be formed by 24 strands of filaments；Filament specifically uses specification as 500D-1000D filaments；In described
Layer of PVC 3 is at least provided with two layers of layer of PVC.
The outer surface of above-mentioned outer layer of PVC 4 is circumferentially spaced, and to be provided with some length directions axially consistent with tube body
Raised reinforcing rib 6.
The outer surface of above-mentioned outer layer of PVC 4 is provided with raised reinforcing rib along tube body length direction is spiral.
The thickness H2 of above-mentioned outer layer of PVC 4 is less than the thickness H1 of middle layer of PVC, and the thickness H3 of interior layer of PVC is less than middle layer of PVC
Thickness H1.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
Enclose, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
