Description

Technical Field

[0001] The utility model relates to the field of corrugated pipes, in particular to a double-wall corrugated pipe with a deflection degree. Background Art

[0002] With the acceleration of the industrialization and urbanization processes, the demand for high-quality, high-pressure-resistant and flexible pipe systems is increasing continuously. In addition, when a circular pipe is buried underground, a layer of fine sand needs to be laid at the pipe armpit to increase the contact surface, form a soil-pipe co-supporting structure, and slow down the deformation of the pipe material. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a double-wall corrugated pipe with a deflection degree, which has high flexibility and pressure resistance, and can meet the pipeline application requirements in various complex environments and special requirements.

[0004] To achieve the above purpose, the utility model provides a double-wall corrugated pipe with a deflection degree, including an inner pipe. An outer corrugated pipe is arranged on one side of the inner pipe. A first wear-resistant layer is arranged on the outer layer of the outer corrugated pipe. The outer corrugated pipe includes a peak-packing section and a straight section. An elastic filler is arranged in the peak-packing section. A folding plate is arranged in the elastic filler. The folding plate is in a V shape. A reinforcing layer is sleeved on the inner pipe. A second wear-resistant layer is arranged between the reinforcing layer and the folding plate. The peak-packing sections are connected by telescopic thin rods.

[0005] Preferably, a corrosion-resistant layer is arranged on the inner layer of the inner pipe.

[0006] Preferably, both the first wear-resistant layer and the second wear-resistant layer can be epoxy ceramic coatings, phenolic epoxy coatings, polyurethane coatings, inorganic zinc coatings.

[0007] Preferably, the elastic filler can be polyurethane foam, microcellular rubber, silica gel, polyurethane foam.

[0008] Preferably, the reinforcing layer is a braided telescopic pipe made of stainless steel metal.

[0009] Preferably, the telescopic thin rod is made of stainless steel metal braiding, and can also be other elastic materials.

[0010] Therefore, the utility model adopts the above-mentioned double-wall corrugated pipe with a deflection degree, and the technical effects are as follows:

[0011] (1) The arrangement of the reinforcing layer can play a protective role when the corrugated pipe elongates. In addition, since the reinforcing layer is made of stainless steel braiding, it has certain telescopic performance and can better cooperate with the elongation and shortening of the corrugated pipe.

[0012] (2) A folding plate is provided to support the peak section of the corrugated pipe. At the same time, the folding plate of this application has the characteristics of elongation and shortening. Therefore, when using the corrugated pipe, it can cooperate with the telescopic thin rod to achieve the effects of elongation and shortening. Description of the Drawings

[0018] The technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0019] Unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those of ordinary skill in the field to which the present utility model belongs.

[0020] Embodiment 1

[0021] As Figures 1-3 shown, a double-wall corrugated pipe with flexibility includes an inner pipe 1. On one side of the inner pipe 1, an outer corrugated pipe 2 is provided. A first wear-resistant layer 3 is provided on the outer layer of the outer corrugated pipe 2. The outer corrugated pipe 2 includes a peak section 21 and a straight section 22. An elastic filler 4 is provided in the peak section 21. A folding plate 5 is provided in the elastic filler 4. The folding plate 5 is in a V shape. A reinforcing layer 6 is sleeved on the inner pipe 1. A second wear-resistant layer 7 is provided between the reinforcing layer 6 and the folding plate 5. The peak sections 21 are connected by a telescopic thin rod 8.

[0022] A corrosion-resistant layer 9 is provided on the inner layer of the inner pipe 1, which can be used to transport corrosive substances and increase the application range of the double-wall corrugated pipe.

[0023] Both the first wear-resistant layer 3 and the second wear-resistant layer 7 can be epoxy ceramic coatings, phenolic epoxy coatings, polyurethane coatings, or inorganic zinc coatings. Providing the first wear-resistant layer 3 on the surface of the corrugated pipe can reduce the wear of the outer corrugated pipe 2. When providing the second wear-resistant layer 7, since both the folding plate 5 and the reinforcing layer 6 are made of stainless steel metal, a second wear-resistant layer 7 is provided to prevent mutual influence during use.

[0024] The elastic filler 4 can be polyurethane foam, microcellular rubber, silica gel, or polyurethane foam. These materials are all elastic materials that can not only fill the peak package section 21 but also be compressed when the double-wall corrugated pipe bends and the double-wall corrugated pipe elongates.

[0025] The reinforcing layer 6 is a braided telescopic pipe made of stainless steel. The outer corrugated pipe 2 has an elongation effect. The reinforcing layer 6 is a metal-braided telescopic pipe and also has a certain elongation effect. Therefore, it can cooperate with the outer corrugated pipe 2 to maximize the elongation effect.

[0026] The telescopic thin rod 8 is made of stainless steel metal braiding and can also be made of other elastic materials. The telescopic thin rod 8 here can cooperate with the deformation of the peak package section 21.

[0027] Therefore, the above-described double-wall corrugated pipe with a certain degree of flexure of the present utility model has high flexibility and pressure resistance and can meet the pipeline application requirements in various complex environments and special requirements.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
