Abstract
The utility model discloses a high strength double -walled bellows, including outer with the level and smooth inlayer of the integrative annular structure of making, vacuole formation between skin and the inlayer, the outer outside has protruding its surface that makes of a plurality of and is the unevenness form, and be equipped with the elastic layer between skin and the inlayer in the cavity that forms. Wherein, the outer of unevenness makes it have better elastic deformation to increase compressive strength, and vacuole formation between the two -layer pipe wall of outer and inlayer, be used for strengthening the whole compressive strength of pipeline equally.
Description
Technical field
This utility model belongs to tubing technical field, is specifically related to the double-wall corrugated pipe of a kind of high intensity.
Background technology
Double-wall corrugated pipe, is a kind of novel tube with circulus outer wall and smooth internal walls, has the advantage such as weight and light, proof to external pressure, sanitation performance are good, construction is fast, life-span length；Stable chemical nature simultaneously, and there is good electrical insulating property, ageing-resistant and ESCR ability strong, broad application temperature range, and there is good comprehensive mechanical performance, bearing capacity is strong, integration engineering cost more advantage, saving big and fund and engineering time for users without pressure water, blowdown and communication cable engineering field, it is the desirable substitute products of conventional discharge blowdown tubing.Due to the cost of the performance of its excellence and relatively economical, have been obtained for great promotion and application in the developed country such as American-European.
Along with the application of double-wall corrugated pipe is more and more extensive, apply to building, communication, agricultural gradually, it is frequently necessary to be embedded in underground use, and double-wall corrugated pipe of the prior art is in use, it is subject to the extruding of various pressure for a long time, greatly reduce the service life of double-wall corrugated pipe, it is easy to cause immeasurable serious consequence.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes the high intensity double-wall corrugated pipe that a kind of resistance to pressure is good, existing double-wall corrugated tubular construction is improved so that it is meet the occasion of various high demand.
In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that, a kind of high intensity double-wall corrugated pipe, including outer layer and the smooth internal layer of the circulus being made into integration, forming cavity between outer layer and internal layer, the outside of outer layer has several projections makes its surface be roughness；And it is provided with elastic layer in the cavity formed between outer layer and internal layer.Wherein, rough outer layer makes it have better elastic deformation, thus increasing comprcssive strength, and forms cavity between the two-layer tube wall of outer layer and internal layer, equally in order to strengthen the entire compression intensity of pipeline.
Wherein, described elastic layer is butadiene-styrene rubber, butadiene rubber, isoprene rubber, EP rubbers, butyl rubber, neoprene or nitrile rubber.The setting of elastic layer, further enhances the comprcssive strength of pipeline.
Further, described internal layer is the internal layer of a tubular structure, and the inside and outside wall of internal layer is smooth structure.The internal layer of tubular structure breaks because being subject to the extruding of the pressure of high intensity for preventing outer layer further.
Further, described outer layer is the outer layer of a tubular structure, and the outer layer of tubular structure breaks because being subject to the extruding of the pressure of high intensity for preventing outer layer further.
Further, the port of this high intensity double-wall corrugated pipe is additionally provided with multiple through hole, through hole run through internal layer, outer layer and arrange, for instance for the flange hole of mounting flange, for the osculum of draining.
This utility model passes through such scheme, and the arranged outside of the outer layer of high intensity double-wall corrugated pipe is roughness, extends the service life of high intensity double-wall corrugated pipe.Between internal layer and outer layer, additionally also fill elastic layer, greatly strengthen the comprcssive strength of entirety, the occasion of various high demand can be met.Meanwhile, the outer layer of tubular structure and internal layer also improve compressive resistance equally.It addition, this utility model adopts the structure being made into integration, convenient making, it is simple to industrialization produces, and has good practicality.
Accompanying drawing explanation
Fig. 1 is the sectional view of embodiment 1 of the present utility model；
Fig. 2 is the sectional view of embodiment 2 of the present utility model.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
Embodiment 1
As a specific embodiment, referring to Fig. 1, a kind of high intensity double-wall corrugated pipe of the present utility model, including outer layer 1 and the smooth internal layer 2 of the circulus being made into integration, forming cavity between outer layer 1 and internal layer 2, the outside of outer layer 1 has several projections 3 makes its surface be roughness；And it is provided with elastic layer 4 in the cavity formed between outer layer 1 and internal layer 2.Wherein, rough outer layer 1 makes it have better elastic deformation, thus increasing comprcssive strength, and forms cavity between the two-layer tube wall of outer layer 1 and internal layer 2, equally in order to strengthen the entire compression intensity of pipeline.
Elastic layer 4 can be continuous print, it is also possible to be interrupted, it is possible to be filled in whole cavity, it is also possible to be filling part cavity.In the present embodiment, referring to Fig. 1, elastic layer 4 be filled with between internal layer 2 and outer layer 1 formed whole cavity.Elastic layer 4 can be that butadiene-styrene rubber, butadiene rubber, isoprene rubber, EP rubbers, butyl rubber, neoprene or nitrile rubber realize.The setting of elastic layer, further enhances the comprcssive strength of pipeline.
It addition, in the present embodiment, internal layer 2 is the internal layer of a tubular structure, and the inside and outside wall of internal layer 2 is smooth structure.The internal layer of tubular structure breaks because being subject to the extruding of the pressure of high intensity for preventing outer layer further.
Meanwhile, in the present embodiment, outer layer 1 is also a tubular structure, and the outer layer of tubular structure can be used for preventing outer layer further and breaks because being subject to the extruding of the pressure of high intensity.
Embodiment 2
In the present embodiment, referring to Fig. 2, elastic layer 4 is sequential like, and fills a part for the cavity formed between internal layer 2 and outer layer 1.
In above-described embodiment, the port of this high intensity double-wall corrugated pipe also can arrange multiple functional through hole, and through hole runs through internal layer and outer layer and arranges, for instance for the flange hole of mounting flange, for the osculum of draining.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
