Abstract
The utility model discloses a high-pressure PVC plastic rib spiral reinforced tube. The high-pressure PVC plastic rib spiral reinforced tube comprises an inner tube body which is made of soft PVC materials. The outer surface of the inner tube body is covered with a cable winding layer. An outer tube layer made of soft PVC materials is wrapped on the outer surface of the cable winding layer. The cable winding layer is wound between the inner tube body and the outer tube layer, the inner tube body is fastened through the cable winding layer to form a cross reinforcing layer, and meanwhile the cable winding layer and the inner tube body made of soft PCV materials are connected into a whole, the pressure bearing strength of the inner tube body is improved, and therefore higher pressure can be borne; in addition, a spiral cable core made of hard PVC materials is spirally wound on the outer surface of the outer tube layer, the outmost layer of spiral cable core rubs the ground in the transportation and use process, the phenomenon that damage occurs when the outer tube layer made of soft PVC materials rubs the ground is avoided, and the service life of the high-pressure PVC plastic rib spiral reinforced tube is greatly prolonged.
Description
Technical field
The utility model relates to plastic tube goods, and particularly a kind of PVC that can bear high pressure moulds muscle helically reinforced pipe.
Background technique
Conventional PVC moulds muscle volute at present, to adopt the embedded hard of PVC composite to mould the product of muscle spiral skeleton, its product is to extrude soft, hard PVC material by two soft, hard extruders, through co-extrusion die head, extrude suitable shape, by spiral forming machine, be rotated into pipe and pass through again tank cooling and shaping.It mainly bears interior pressure by spiral helicine hard PVC core, and when bearing while pressing compared with imperial palace, the easy lengthening deformation of spiral skeleton, causes bearing capacity to decline; And conventional PVC moulds muscle volute in transportation and using process, outer surface and ground friction, the flexible PVC attenuation of easily wearing and tearing, causes bearing capacity decline, has influence on PVC and moulds muscle volute working life.
Model utility content
In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, and its bearing capacity is strong, and during use, connection part can not be elongated, and the anti abrasive PVC of its appearance moulds muscle helically reinforced pipe.
The utility model for the technological scheme that solves its technical problem and adopt is:
High pressure PVC moulds a muscle helically reinforced pipe, comprises the inner tube of being made by flexible PVC material, and the outside of this inner tube is coated with one deck netting twine winding layer, and the appearance of described netting twine winding layer is enclosed with the external tube layer that one deck is made by flexible PVC material.
The spiral winding core that the appearance spiral winding of described external tube layer has one deck to be made by hard PVC material.
The beneficial effects of the utility model are: because the utility model is wound with one deck netting twine winding layer between inner tube and external tube layer, by netting twine winding layer by inner tube banding, form an intersection strengthening course, netting twine winding layer is connected with the inner tube of being made by soft PCV material simultaneously, improved the bearing strength of inner tube, thereby can bear higher pressure, the appearance of the external tube layer spiral core that also spiral winding has one deck to be made by hard PVC material in addition, in transportation and using process, by outermost spiral core and ground friction, avoid the external tube layer made by flexible PVC material because of with the ground friction phenomenon that is damaged, extended widely the working life that high pressure PVC of the present utility model moulds muscle helically reinforced pipe.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is partial sectional view of the present utility model;
Fig. 2 is that the utility model is along the tangent plane schematic diagram of the axial direction of body;
Fig. 3 is the anti-interior test chart of pressing of product of the present utility model and traditional product.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of high pressure PVC moulds muscle helically reinforced pipe, comprise the inner tube 1 of being made by flexible PVC material, the outside of this inner tube 1 is coated with one deck netting twine winding layer 2, and the appearance of described netting twine winding layer 2 is enclosed with the external tube layer 3 that one deck is made by flexible PVC material.
Further, in order to increase abrasive resistance of the present utility model, the spiral winding core 4 that the appearance spiral winding of described external tube layer 3 has one deck to be made by hard PVC material, product of the present utility model in use, by outermost spiral core 4 and ground friction, avoid the external tube layer 3 made by flexible PVC material because of with the ground friction phenomenon that is damaged, extended widely the working life that high pressure PVC of the present utility model moulds muscle helically reinforced pipe.
The production method of product of the present utility model is as follows:
First soft PVC material is put in single screw extrusion machine, utilize single screw extrusion machine to extrude inner tube 1, then utilize spiral forming machine that inner tube 1 is rotated into pipe, afterwards inner tube 1 is put in tank cooling, then inner tube 1 is put in baking box and dried again, on the interior tube-surface of recycling winding machine after oven dry, be wound around intersection last layer netting twine winding layer 2, in addition utilize afterwards two single screw extrusion machines to extrude soft, hard PVC material forms external tube layer 3 and spiral winding core 4 through co-extrusion die head from the inside to the outside successively in the appearance of the netting twine winding layer 2 of body, then the body after moulding is put into cooling and shaping in tank, the length that can be decided according to the actual requirements afterwards cutting body is also furled.
With reference to Fig. 3, in figure, A line represents the anti-interior figure line of pressing of traditional product, B line represents the anti-interior figure line of pressing of product of the present utility model, from the PVC of graphic analyses the utility model structure, moulding muscle helically reinforced pipe spreading rate can be controlled at below 25%, and conventional P VC moulds muscle volute spreading rate, be up to 140%, the PVC that its internal pressure strength is starkly lower than the utility model structure moulds muscle helically reinforced pipe.
The foregoing is only preferential mode of execution of the present utility model, as long as within the technological scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
