Description
Technical field
It the utility model is related to a kind of composite PVC cable duct tube.
Background technology
The pipe material that in the market is used as plastic cable protection substantially has two major classes, and one kind is thermosetting plastics, wherein
Based on GRP pipe, another kind is thermoplastic, based on PVC, polyethylene, PA tube.This two big types of material
Pipeline advantage and disadvantage it is as follows：
The advantages of frp cable protective pipe road：(1) GRP pipe is light-weight, rigidity is high, resistance to compression and anti-settling ability
By force；(2) thermal conductivity factor is big, and especially when underground is run, advantage becomes apparent from cable for a long time；(3) the resistance to temperature difference is good, -40 DEG C~-
Service life was up to 50 years in 150 DEG C of environment.Frp cable protective pipe road is rough due to technique defect itself and illegal producer
Make excessively, no alkali product is served as with high alkali product, the factor such as adulterate, its quality is uneven, and traction steel is cannot stand when wearing cable
The friction of silk, scratch, and result in glass fibre delamination, causes glass fibre to be entangled on cable, the more twine the more more, can neither advance,
It can not retreat, cause to wear cable failure, it is impossible to realize that safety wears the purpose of cable, be faced with the danger being eliminated.
The advantages of thermoplastic pipes such as PVC, polypropylene, polyethylene, is very much, applies in cable protection field, outstanding feature is just
It is good electrical insulating property, inner wall smoother, easy cabling, the phenomenon of stuck cable will not be caused to occur.It is but heat-resisting, cold-resistant
There is limitation, it is difficult to reach the needs of power industry technical requirements.Thermoplastic tubing is the relatively common tubing of in the market above,
Respectively there are advantage and disadvantage, but the requirement apart from power industry falls far short.
At present, there is an urgent need for a kind of heat-resisting, high-strength, lightweight, corrosion resistant, fire-retardant, inner wall smooth and again economical and practical in the market
Cable protection pipe.Once there is a kind of the advantages of utilizing thermoplastic and thermosets in the market, by fiberglass and gathered
Propylene carries out the composite cable protection pipe of organic assembling, and still, what it took simply simply makees outer tube, thermoplastic tube by fiberglass
Make inner tube directly in conjunction with method, since thermoplastic is a kind of very typical non-polar crystalline material, surface tension compared with
Low, shrinking percentage is big, and creep-resistant property is poor, and product size stability is poor, easily produces buckling deformation, it is difficult to be adsorbed with other materials
Together, cause occur gap among the tubing of two kinds of materials, intensity is low., can be by inner tube even during trailing cable
Come to hauling out, do not reach the purpose of market demands.
Utility model content
The purpose of this utility model is to provide a kind of composite PVC cable duct tube, solves existing composite PVC cable duct tube
Take simply fiberglass is simply made into outer tube, thermoplastic tube make inner tube directly in conjunction with method, since thermoplastic is one
The very typical non-polar crystalline material of kind, surface tension is relatively low, and shrinking percentage is big, and creep-resistant property is poor, product size stability
Difference, easily produces buckling deformation, it is difficult to be attached together with other materials, causes gap occur among the tubing of two kinds of materials,
Intensity is low；, can be next to hauling out by inner tube even during trailing cable, do not reach the purpose problem of market demands.
Technical solution is used by the utility model solves its technical problem：A kind of composite PVC cable duct tube, including electricity
Cable catheter channels and the glass reinforced plastic pipe cable duct tube inner tube outer surface being integrally formed on cable duct tube inner tube outer surface prolong its axis
To the screw thread pillar for being provided with continuous thread groove and being arranged between connected two thread groove, screw thread pillar and thread groove
In double-spiral structure；One group of biodegradable vulcanised rubber layer is formed on the outer surface of glass reinforced plastic pipe, it is biodegradable
Vulcanised rubber layer outer surface forms one group of antiskid thread.
Further, thread groove, screw thread pillar cover whole cable duct tube inner tube outer surface.
Further, vulcanised rubber layer is arranged on the outer surface of glass reinforced plastic pipe both ends and middle part.
Further, it is equipped with quartz sand resin mixed layer in thread groove, the quartz sand resin in the thread groove
The outer surface of mixed layer and the outer surface of inner tube are flush.
Further, the cross section of thread groove is in funnel-form, and its underpart diameter is less than upper diameter, and its underpart bottom is
Recessed arc surface.
Further, screw thread pillar is tapered, its top is arc-shaped；Screw thread pillar and thread groove outer surface are provided with
Frosted layer
The beneficial effects of the utility model：Thread groove, screw thread pillar and matching somebody with somebody for quartz sand resin mixed layer merge spiral shell
Line groove covers whole cable duct tube inner tube outer surface, can not only make glass reinforced plastic pipe be closely combined into inner tube one it is whole
Body, the frictional force between inner tube and glass reinforced plastic pipe greatly increase, and avoid inner and outer pipes slippage, and outer pipe surface can be made to be in cylinder
Shape is smoothly set, and thickness is uniform, and outer tube integral strength is consistent, increases rigidity, quartz sand thermal diffusivity itself is good, increases scattered
Heat, so as to extend the service life of whole composite cable conduit.Vulcanised rubber layer being capable of applying in this composite PVC cable duct tube
It is convenient that work and guarantor's fortune provide.
Below with reference to drawings and examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
