Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to fig. 3, which are schematic structural diagrams of the high impact resistance polyethylene double-wall corrugated pipe provided by the present invention. The double-walled corrugated pipe of high impact resistance polyethylene comprises a plurality of corrugated pipe bodies 10 and a metal ring 20 connecting the ends of two adjacent corrugated pipe bodies 10, and further comprises other functional modules, such as PVC additives, lubricants, etc., which should be well known to those skilled in the art, and will not be described in detail herein.
The bellows body 10 includes an annular outer pipe 11, an inner pipe 12 disposed on an inner sidewall of the outer pipe 11, and a plurality of corrugated rings 13 disposed on an outer sidewall of the outer pipe 11 in a spaced-apart relationship.
The outer pipe 11 may be made of high density polyethylene, hereinafter HDPE for short, which has good stability, and high rigidity and toughness, and can be used in a severe environment for a long time. And the acquisition cost is low, and the deliberate maintenance is not needed.
The inner pipe 12 can be made of a rubber layer and is arranged on the inner side wall of the outer pipe 11, and the rubber grid layer can relieve impact of sand on the outer pipe 11 during drainage, so that the service life is prolonged. The inner side wall of the inner pipeline 12 is further provided with a low-density polyethylene layer 121, and the low-density polyethylene layer 121 has good flexibility, is alkali-resistant and general organic solvent-resistant, can protect the inner pipeline 12 from corrosion, and prolongs the service life. It is conceivable that the lengths of the outer pipe 11 and the inner pipe 12 are always the same, so that it is avoided that a plurality of corrugated pipe bodies 10 are connected to form a gap and sand is embedded to affect the sealing performance. The inner side wall of the inner pipeline 12 is wavy in cross section along the axial direction, a plurality of fluctuation sections are arranged along the axial direction, a buffer area is formed in each fluctuation section, the flow guiding is facilitated, and the uneven sinking and floating of soil sand can be adapted.
The corrugated rings 13 are axially spaced apart on the outer side wall of the outer pipe 11. The corrugated ring 13 is embedded with a steel strip supporting layer 131, the cross section of the corrugated ring 13 is arc-shaped, and the compression resistance and impact resistance of the outer pipeline 11 can be greatly improved, so that the corrugated pipe main body 10 can be used in an environment which can be pressed or even impacted for a long time. Axial reinforcing ribs 132 are axially and protrudingly arranged between any two adjacent corrugated rings 13 on the outer side wall of the outer pipeline 11, and the plurality of axial reinforcing ribs 132 are distributed in two groups and are respectively positioned at the outer sides of the two radial ends of the outer pipeline 11. An air outlet 133 is formed in the axial reinforcing rib 132. The axial ribs 132 can further improve the bending resistance of the outer pipe 11. The length of the air outlet 133 is the same as that of the axial reinforcing rib 132, and the air outlet is used for discharging redundant air during production, so that bubbles are avoided, the qualification rate is improved, the material consumption is reduced, and the cost is reduced.
The diameter of the inner sidewall of the metal ring 20 is slightly larger than that of the outer sidewall of the outer pipe 11, or is equal to that of the outer sidewall of the outer pipe 11, so as to ensure that the metal ring can be sleeved outside the end of the corrugated pipe body 10. It is conceivable that the metal ring 20 can be designed into different specifications according to the shapes of the outer walls of different pipelines, in this embodiment, the metal ring 20 is designed with two circular arc-shaped protrusions 21 matched with the axial ribs 132, and the ribs 132 are located in the protrusions 21.
The inner side wall of the metal ring 20 is provided with a hot melt adhesive layer 22. Namely, after the metal ring 20 connects and fixes the end portions of the two corrugated pipe main bodies 10, the hot melt adhesive layer 22 can be softened by heating the metal ring 20, so as to fill up the end connection gap between the two corrugated pipe main bodies 10, and after cooling, the metal ring 20 and the corrugated pipe main body 10 are bonded by hot melt adhesive, so that the metal ring 20 and the corrugated pipe main body 10 are connected more firmly and are not easy to fall off. When the metal ring 20 connects the ends of the two corrugated tube bodies 10, the connection error can be reduced, and the pipe joint can be prevented from being damaged and leaking.
Compared with the prior art, the utility model provides a high anti impact polyethylene double-walled bellows is in the ripple intra-annular has set up steel band supporting layer 131, and with the becket 22 cooperation makes it have advantages such as light in weight, external pressure resistant, long service life. Meanwhile, the high-impact-resistance polyethylene double-wall corrugated pipe is stable in chemical performance, good in electrical insulation, strong in ageing resistance and environmental cracking resistance, and wide in application temperature range. The end part connected through the metal ring 22 and the hot melt adhesive has higher surface flatness, the sealing performance is good, the installation efficiency can be greatly improved, and the interface strength is high. Meanwhile, the corrugated ring with the steel belt supporting layer 131 can greatly improve the pressure resistance and impact resistance of the high-impact-resistance polyethylene double-wall corrugated pipe, reduce the connection error of a pipeline interface and avoid the damage and leakage of the pipeline interface.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
