Abstract
The utility model discloses a kind of enhanced dual anti-bellowss of bilayer of internal-rib; including bellows wall and smooth internal walls; one layer of protective bulkhead is wrapped up outside the bellows wall; the protective bulkhead is formed in parallel with the articulamentum of inner wall between two adjacent bellows walls, and the gap of the articulamentum and inner wall is equipped with vertical and connects the pillar on the inside of inner wall outside and articulamentum.The dual anti-bellows of bilayer of the utility model, can improve the shock resistance of bellows, improve the support construction of bellows, improve tubing resistance to compression degree.
Description
Technical field
The utility model relates to pipeline fields, in particular to arriving a kind of enhanced dual anti-bellows of bilayer of internal-rib.
Background technique
High density polyethylene (HDPE) (HDPE) double-wall corrugated pipe is a kind of New pipe with cyclic structure outer wall and smooth internal walls
Material, the beginning of the eighties succeed in developing first in Germany.In China, the promotion and application of HDPE double-wall corrugated pipe are in rising situation
Stage, all technical reach using standard.High density polyethylene (HDPE) (HDPE) has excellent chemical stability, ageing-resistant
And the performance of resisting environmental stress and cracking.Belong to flexible pipe by it for the HDPE double-wall corrugated pipe that raw material are produced.
Heavy wall of the existing bellows between two wave crests only has 24 millimeters in the market, encounters when unloading or constructing
Sharp object is damaged sometimes, and shock resistance is poor.
Summary of the invention
Against the above technical problems, the purpose of the utility model is to provide a kind of enhanced dual anti-bellows of bilayer of internal-rib,
The shock resistance for improving bellows, improves the support construction of bellows, improves tubing resistance to compression degree.
To achieve the above object, the utility model is achieved through the following technical solutions: a kind of enhanced bilayer of internal-rib
Dual anti-bellows, including bellows wall and smooth internal walls, the bellows wall wrap up one layer of protective bulkhead outside, and the protective bulkhead is adjacent
It is formed in parallel with the articulamentum of inner wall between two wave crests, the gap of the articulamentum and inner wall is equipped with outside vertical and connection inner wall
Pillar on the inside of side and articulamentum.
It further illustrates, the pillar is 2 or 3.
Compared with prior art, the utility model has the following beneficial effects: by the way that one layer of protective bulkhead is arranged outside bellows wall,
It can make bellows wave crest not cracky, form articulamentum between two adjacent bellows walls, increase the impact resistance of pipeline, even
It connects and is equipped with pillar between layer and inner wall, the resistance to compression degree of tubing can be increased, meanwhile, articulamentum, inner wall form hollow out between pillar
Structure more saves material than entity structure, reduces cost, and can produce certain deformation in compression or stretching, point
Stress is solved, structure is hardly damaged, and structure is simple, and rationally, using effect is good.
Detailed description of the invention
Fig. 1 is for illustrating the dual anti-bellows schematic diagram of the enhanced bilayer of the utility model embodiment internal-rib.
Fig. 2 is for illustrating that the dual anti-ripple tube passage axial section of the enhanced bilayer of the utility model embodiment internal-rib locally shows
It is intended to.
Fig. 3 is used to illustrate the dual anti-ripple tube passage of the enhanced bilayer of the utility model embodiment internal-rib contains a pillar two
The axial section of adjacent peaks.
Fig. 4 is used to illustrate two of the dual anti-ripple tube passage of the enhanced bilayer of the utility model embodiment internal-rib containing more pillars
The axial section of adjacent peaks.
Parts title and serial number in figure: 1- bellows 2- bellows wall 3- inner wall 4- pillar 5- articulamentum.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but is not limited practical
Novel protection scope and application range:
As shown in Figure 1 to Figure 4, the enhanced dual anti-bellows of bilayer of a kind of internal-rib, including bellows wall 2 and smooth internal walls 3, bellows wall
Wrap up one layer of protective bulkhead outside 2, protective bulkhead is formed in parallel with the articulamentum 5 of inner wall 3 between two adjacent wave crests, articulamentum 5 with
The gap of inner wall 3 is equipped with pillar 4 that is vertical and connecting 3 outside of inner wall with 5 inside of articulamentum.By the way that one is arranged outside bellows wall 3
Layer protective bulkhead can make bellows wave crest not cracky, form articulamentum 5 between two adjacent wave crests, increase the anti-of pipeline
Impact is equipped with pillar 4, can increase the resistance to compression degree of tubing between articulamentum 5 and inner wall 3, meanwhile, articulamentum 5, inner wall 3, branch
Engraved structure is formed between column 4, more saves material than entity structure, reduces cost, and can produce in compression or stretching
Raw certain deformation, decomposes stress, and structure is hardly damaged, and structure is simple, and rationally, using effect is good.Preferably, pillar 4 is 2
Root or 3 or 4 or 5, so that engraved structure is more stable, is not easy to be extruded or pull damage, decomposes stress effect more
It is good.
It is that the dual anti-bellows of bilayer enhanced to the utility model internal-rib is expounded above, is used to help understand this reality
With novel, but the embodiments of the present invention and it is not restricted to the described embodiments, it is any to violate under the utility model principle
Made changes, modifications, substitutions, combinations, simplifications should be equivalent substitute mode, be included in the protection of the utility model
Within the scope of.
