Abstract
The utility model discloses a finned tube, encircle the polyvinyl chloride pipe body and the strengthening rib of equidistance setting, vacuole formation between the strengthening rib and the polyvinyl chloride pipe body including the polyvinyl chloride pipe body and spiral, the external subsides of polyvinyl chloride pipe are covered there is the one deck heat preservation, and the heat preservation overcoat is equipped with thermoplasticity elasticity sheath. Through the duplicate protection of heat preservation and thermoplasticity elasticity sheath, the polyvinyl chloride pipe body is difficult for embrittling under low -temperature weather to guaranteed the quality of the polyvinyl chloride pipe body, made it can guarantee long -term compression strength.
Description
Technical field
This utility model belongs to tubing technical field, particularly relates to a kind of riffled tube.
Background technology
Riffled tube refers to inner wall smooth, outer wall is with the tubing of the special construction of radial reinforced rib, owing to radial reinforced rib uses i-beam structure, more traditional straight wall tubing is compared has light weight, intensity advantages of higher, reach same intensity require riffled tube relatively straight wall pipe can material-saving 40-60%, its superior serviceability and good cost performance so that riffled tube is widely used in city-building draining, drainage project.
PVC-U(PVC-U) riffled tube is by the heated extrusion of polyvinyl chloride resin, uses another novel PVC-U pipeline that special dies and forming technology produce, it is the product of the hi-tech development nineties in 20th century.This tubing, under identical compression load ability, saves the material of 30% than common PVC-U solid wall pipe.PVC-U riffled tube is basically identical with PVC-U riffled tube purpose of design, actually the one of structure-wall pipe material.As buried draining, blowdown heavy caliber PVC-U pipe, it is mainly used for: under gravity sewage or rainwater etc. is displaced in sewage farm or rivers,lakes and seas, is widely used in municipal engineering construction.Additionally can be additionally used in the fields such as field irrigation, power communication, cable protection and discharge of industrial wastes.
In general, when riffled tube is embedded in underground use, such as buried drain pipe road, in China winter, especially north of china in winter, it is often subject to the tremble with fear impact of weather of low-temperature frozen and makes riffled tube become the most crisp, if it is overweight at this time to bear external pressure load (usual intrinsic pressure load is ignored), so riffled tube is easy for there will be the phenomenon of fracture, and this just has influence on the extensive application of riffled tube, particularly in the application of bigger city by a definite limitation.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of cold-proof freeze proof riffled tube, existing reinforcement pipe structure 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 riffled tube, and the reinforcement being placed equidistant including polrvinyl chloride body and spiral surrounding polrvinyl chloride body forms cavity between reinforcement and polrvinyl chloride body；Described polyvinyl chloride pipe is external is covered with one layer of heat preservation layer, is arranged with thermoplastic elastic sheath outside heat-insulation layer.By heat-insulation layer and the duplicate protection of thermoplastic elastic sheath, polrvinyl chloride body is difficult to become fragile under microthermal climate, thus ensure that the quality of polrvinyl chloride body so that it is can guarantee that long-term compressive resistance.
Wherein, described heat-insulation layer is to be realized by the neoprene of radiation treatment.The sleeve pipe that described thermoplastic elastic sheath is made up of thermoplastic elastomer (s).
Further, the pitch of described reinforcement is 1-5cm.Shorter reinforcement pitch, more pressure than existing structure.
Further, described reinforcement is to be realized by the polyethylene layer of parcel steel band.
Further, the tube wall of described polrvinyl chloride body is hollow structure (tubular structure), and the inside and outside wall of polrvinyl chloride body is smooth structure.The polrvinyl chloride body of tubular structure not only increases the number of plies of tube wall, enhances heat insulation effect, also reduces permeability equally, and can be used for preventing polrvinyl chloride body and rupture because of extraneous extruding.
This utility model passes through such scheme, has the advantage that
1, this utility model passes through heat-insulation layer and the protection of thermoplastic elastic sheath; polrvinyl chloride body is made to have the function of insulation; when run into low-temperature frozen tremble with fear weather time; polrvinyl chloride body without becoming fragile, thus be ensure that the service life of polrvinyl chloride body by the protection of heat-insulation layer and thermoplastic elastic sheath；
2, this utility model uses the polrvinyl chloride body of hollow structure, can play certain heat-insulating property, still prevents the polrvinyl chloride body at center and ruptures because of extraneous extruding, improves overall quality further, extend service life；
3, this utility model is skillfully constructed, simple in construction, it is easy to accomplish, 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.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
As a specific embodiment, see Fig. 1, a kind of riffled tube of the present utility model, the reinforcement 2 being placed equidistant including polrvinyl chloride body 1 and spiral surrounding polrvinyl chloride body 1, between reinforcement 2 and polrvinyl chloride body 1, form cavity；It is covered with one layer of heat preservation layer 3 outside described polrvinyl chloride body 1, outside heat-insulation layer 3, is arranged with thermoplastic elastic sheath 4.Wherein, heat-insulation layer 3 is to be realized by the neoprene of radiation treatment.The sleeve pipe that described thermoplastic elastic sheath 4 is made up of thermoplastic elastomer (s).By heat-insulation layer 3 and the protection of thermoplastic elastic sheath 4; polrvinyl chloride body 1 is made to have the function of insulation; when run into low-temperature frozen tremble with fear weather time, polrvinyl chloride body 1 without becoming fragile, thus be ensure that the service life of polrvinyl chloride body 1 by the protection of heat-insulation layer 3 and thermoplastic elastic sheath 4.Thermoplastic elastic sheath 4 is except playing the effect of insulation, moreover it is possible to play the effect of buffering, and decomposable asymmetric choice net arrives the pressure on polrvinyl chloride body.
In the present embodiment, reinforcement 2 is to be realized by the polyethylene layer of parcel steel band.
It addition, the pitch scope of reinforcement 2 is 1-5cm.Compared with prior art, shorten the pitch of reinforcement, more pressure than existing structure.
It addition, see Fig. 1, the tube wall of polrvinyl chloride body 1 is hollow structure (tubular structure), and the inside and outside wall of polrvinyl chloride body 1 is smooth structure.The polrvinyl chloride body 1 of tubular structure not only increases the number of plies of tube wall, enhances heat insulation effect, also reduces permeability equally, and can be used for preventing polrvinyl chloride body 1 and rupture because of extraneous extruding.
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.
