Description

High-strength vinyl chloride double-wall corrugated pipe

Technical Field

The utility model relates to a bellows technical field specifically indicates a high strength chloroethylene double-walled bellows.

Background

The polyethylene double-wall corrugated pipe is a novel pipe with an outer wall with an annular structure and a smooth inner wall, and is firstly developed in Germany in the early 80 s. After more than ten years of development and improvement, the product series is developed from a single variety to a complete product series. The production process and the use technology are mature at present. Due to the excellent performance and the relatively economic cost, the method has been greatly popularized and applied in developed countries such as Europe and America. However, in the use process of the prior art, the phenomenon that the corrugated pipe is broken due to overlarge pressure often occurs in the transportation and use processes of the corrugated pipe. To this end, a high strength vinyl chloride double wall corrugated pipe has been proposed.

SUMMERY OF THE UTILITY MODEL

The present invention is to solve the above problems and to provide a high strength vinyl chloride double-wall corrugated pipe.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a high strength vinyl chloride double-walled bellows, includes the inner tube, sets up the outer bellows outside the inner tube which characterized in that: the corrugated pipe is characterized in that a wave crest is arranged on the outer corrugated pipe, a supporting piece is arranged in the wave crest, a plurality of reinforcing ribs are further arranged on the outer corrugated pipe, and reinforcing rods are further arranged on the inner pipe and are triangular reinforcing rods.

Further preferred is: the support piece is a semicircular support piece, and a support rod is further arranged on the support piece.

The utility model has the advantages that:

1. the utility model discloses be provided with support piece in the crest of outer bellows, can play the effect of support to the crest through support piece to increase the compressive strength of outer bellows, avoid the bellows to break.

2. The utility model discloses be provided with a plurality of strengthening ribs on the bellows outward, with returning the strengthening rib and can support the crest in the bottom, increase the compressive capacity of crest to increase the intensity of bellows, avoid the bellows to break.

3. The utility model discloses be provided with the triangle-shaped stiffener on the inner tube, can increase the compressive capacity of inner tube through the triangle-shaped stiffener, triangle-shaped's design makes the structure of stiffener and inner tube more stable simultaneously, and then increases the intensity of bellows.

Detailed Description

The high-strength vinyl chloride double-wall corrugated pipe of the present invention will be further described with reference to fig. 1-4.

Referring to fig. 1 to 4, the high strength vinyl chloride double-wall corrugated pipe of the present embodiment includes an inner pipe 1, and an outer corrugated pipe 2 disposed outside the inner pipe 1, wherein: the outer corrugated pipe 2 is provided with a wave crest 201, a supporting piece 3 is arranged in the wave crest 201, and the outer corrugated pipe 201 is also provided with a plurality of reinforcing ribs 202; the inner pipe 1 is also provided with a reinforcing rod 101, and the reinforcing rod 101 is a triangular reinforcing rod; the supporting part 3 can support the wave crest 201 to increase the strength of the wave crest 201, meanwhile, the reinforcing ribs 202 can limit and fix the bottom of the wave crest 201 and increase the strength of the outer corrugated pipe 2, so that the purpose of increasing the strength of the corrugated pipe is achieved, and the corrugated pipe is prevented from being damaged by pressure in the transportation and use processes; the reinforcing rods 101 can support the inner pipe 1, and meanwhile, the triangular reinforcing rods enable the structure of the inner pipe 1 to be more stable, so that the strength of the corrugated pipe is never increased.

Referring to fig. 1-4, the supporting member 3 is a semicircular supporting member, and a supporting rod 301 is further disposed on the supporting member 3; semicircular support piece can be inseparabler with the laminating of crest, and the support effect of playing is also better, and bracing piece 301 can increase support piece 3's intensity simultaneously to increase the compressive strength of bellows.

The utility model discloses a forming process as follows: firstly, an inner pipe 1 and a reinforcing rod 101 are extruded and molded through an extruder, then a supporting piece 3 is installed in a wave crest 201 of an outer corrugated pipe 2, then a roller glue machine is used for roller coating of a bonding agent on the inner pipe 1, and finally the inner pipe 1 is jacked into the outer corrugated pipe 2 through a rotary pipe jacking machine, so that the bonding agent can be uniformly coated between the inner pipe 1 and the outer corrugated pipe 2 through rotary jacking, and after cooling and shaping, the forming is completed.

The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
