Abstract
The utility model relates to a composite V-shaped steel belt-reinforced polyethylene helical bellows which comprises a bellows body and an inner cavity. The bellows body comprises an inner layer, a reinforcing layer and an outer layer; the inner layer and the outer layer of the bellows body are made of polyethylene material; the reinforcing layer is made of a steel belt; the steel belt is wound on the middle portion of the inner wall of the bellows body and enables the bellows body to be corrugated in shape; the steel belt is belt to be V-shaped; an adhesive resin layer is applied between the steel belt and the polyethylene material of the outer layer; and the inner surface of the steel belt is coated with a resin layer. Compared with the prior art, the steel belt is wound on the middle portion of the inner wall of the bellows body and enables the bellows body to be corrugated in shape, so that the rigidity and strength of the polyethylene pipe are improved effectively, the diameters and pressure resistance of the pipelines are increased and the polyethylene pipes are suitable for drain pipes or sewage collection pipes with large opening diameters. The composite V-shaped steel belt-reinforced polyethylene helical bellows enjoys promising prospect and can replace the conventional large-opening diameter drain pipes.
Description
Technical field
The utility model relates to polyethylene pipe, especially a kind of heavy caliber V-arrangement steel band composite reinforced polyethylene helical bellows that is applicable to waste pipe.
Background technique
At present, municipal drainage pipe and sewage collecting pipe are generally the water pipes of being made by concrete, the employing cast iron tube or the polyethylene pipe that also have.The existing polyethylene pipe for waste pipe or sewage collecting is all the pipeline that diameter is less conventionally, and its compressive strength is also less, and using scope is narrower, can not adapt to draining or the sewage collecting work of large flow or larger pressure.
Model utility content
For the deficiency of above existing polythene drainpipe, the purpose of this utility model is to provide a kind of heavy caliber V-arrangement steel band composite reinforced polyethylene helical bellows that is applicable to waste pipe or sewage collecting pipe.
The purpose of this utility model is achieved by the following technical solution:
V-arrangement steel band composite reinforced polyethylene helical bellows, comprise body and inner chamber, described body is comprised of internal layer, enhancement layer and skin, the internal layer of described body and skin are all to be made by polythene material, described enhancement layer consists of steel band, steel strip winding is in the centre of inboard wall of tube body and make body form bellows-shaped, and described steel band bends to v-shaped structure.
As optimal technical scheme of the present utility model, between described steel band and outer field polythene material, be coated with adhering resin layer.
As optimal technical scheme of the present utility model, the internal surface of described steel band is coated with protection resin layer.
The beneficial effects of the utility model are: with respect to prior art, the utility model adopts steel strip winding in the centre of inboard wall of tube body and makes body form bellows-shaped, effectively strengthened the Rigidity and strength of polyethylene pipe, improved diameter and the voltage endurance capability of pipeline, thereby can make polyethylene pipe be applicable to bigbore waste pipe or sewage collecting pipe.Working life of the present utility model is longer, and application area is larger, can substitute traditional heavy caliber drain pipe and sewage collecting pipe.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local structure for amplifying schematic diagram at A place in Fig. 1.
In figure: 1, skin, 2, steel band, 3, adhering resin layer, 4, internal layer, 5, protection resin layer.
Embodiment
As depicted in figs. 1 and 2, V-arrangement steel band composite reinforced polyethylene helical bellows, comprise body and inner chamber, described body is comprised of internal layer 4, enhancement layer and outer 1, the internal layer 4 of described body and outer 1 is all to be made by polythene material, described enhancement layer consists of steel band 2, and steel band 2 is wrapped in the centre of inboard wall of tube body and makes body form bellows-shaped.
In the present embodiment, described steel band 2 bends to v-shaped structure, between steel band 2 and outer 1 polythene material, is coated with adhering resin layer 3, and the internal surface of steel band is coated with protection resin layer 5.The utility model gets up the advantages such as corrosion-resistant, wear-resistant and pliability of the high rigidity of steel and high strength and plastics, not only can make tubing reach SN8, SN12.5, tri-other ring stiffness of level of SN16, and solved the corrosion-resistant problem of steel, made up the weakness that larger diameter all-plastic buried drain pipe ring stiffness can only reach SN8.
