Abstract
The utility model relates to a corrugated pipe, which belongs to the technical field of the conveying pipeline. The corrugated pipe is a hollow pipe of a corrugated structure and is used for conveying heat, steam and the like. The corrugated pipe comprises an outer connecting layer and an inner connecting layer, which are fixedly connected with each other, wherein a heat-preserving material is filled inside a space formed between the outer and the inner connecting layers, the surfaces of the outer and the inner connecting layers are provided with concave waves and convex waves, and at least one end of the corrugated pipe is provided with a wide mouth with a smooth surface. The corrugated pipe which is obtained through the above technical scheme can save the raw materials because both the inner and the outer connecting layers are a thin layer; and since the heat-preserving material is arranged between the outer and the inner connecting layers, the corrugated pipe has a good heat-preserving effect, favors the conveying of the materials requiring the heat preservation such as heat, steam and the like, and is popular among consumers.
Description
Technical field
The utility model belongs to the conveyance conduit technical field, is specifically related to a kind of bellows of aesthetic in appearance and reliable performance rational in infrastructure.
Background technique
Conveyance conduit is widely used in water supply, draining, blowdown, exhaust, subway ventilation, mine ventilation, field irrigation etc.Present a lot of cement pipe that use etc. substantially all are level and smooth straight shape pipes, and it is inconvenient to install, and the simple plastic tube of use is also arranged, and it is withstand voltage and impact strength is low, and geological adaptability is poor, and application area is restricted, and working life is short.
Summary of the invention
At the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of bellows of aesthetic in appearance and reliable performance rational in infrastructure.
Described a kind of bellows, comprise bellows body with spiral helicine concavo-convex ripple, described bellows body comprise the interconnective external layer that constitutes by the PE composite material and in connect layer, connecing layer internal surface in described is smooth structure, it is characterized in that described protruding ripple place is equipped with the U-shaped steel band, described U-shaped steel band be equipped with in external layer and in connect between the layer.
Described a kind of bellows, it is characterized in that described external layer and in connect layer and melt by electric heating and be connected.
Described a kind of bellows, it is characterized in that described external layer and in connect layer and be welded to connect by inside and outside extruding.
Described a kind of bellows is characterized in that described protruding ripple tangent to helix and horizontal angle are 20-40 °.
Above-mentioned a kind of bellows, comprise bellows body with spiral helicine concavo-convex ripple, described bellows body comprise the interconnective external layer that constitutes by the PE composite material and in connect layer, connecing layer internal surface in described is smooth structure, described protruding ripple place is equipped with the U-shaped steel band, described U-shaped steel band be equipped with in external layer and in connect between the layer.The bellows of the utility model by adopting above-mentioned technology to obtain, interior external layer all is a thin layer, and conservation is provided with the U-shaped steel band between protruding ripple two-layer, and soundness is good, can increase the service life, and has obtained liking of Consumer.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A place enlarged view among Fig. 1.
Among the figure: 1-bellows body connects layer, the external layer of 3-, 4-U shape steel band in the 2-.
Embodiment
The utility model will be further described below in conjunction with Figure of description:
As shown in Figure 1, a kind of bellows, comprise bellows body 1 with spiral helicine concavo-convex ripple, described bellows body 1 comprise the interconnective external layer 3 that constitutes by the PE composite material and in connect layer 2, connecing layer 2 internal surface in described is smooth structure, it is characterized in that described protruding ripple place is equipped with U-shaped steel band 4, described U-shaped steel band 4 be equipped with in external layer 3 and in connect between the layer 2.Described external layer 3 and in connect layer 2 by electric heating molten is connected or inside and outside extrude and be welded to connect, reach other similar Placements, also directly the socket cooperation gets final product.Described protruding ripple tangent to helix and horizontal angle are 20-40 °.
The bellows of the utility model by adopting above-mentioned technology to obtain, interior external layer all is a thin layer, and conservation is provided with the U-shaped steel band between protruding ripple two-layer, and soundness is good, can increase the service life, and has obtained liking of Consumer.
