A kind of reinforced plastic pipeTechnical field
The utility model belongs to engineering material technical field, relates to a kind of tubing, specifically relates to a kind of reinforced plastic pipe.
Background technique
Plastic tube is generally is raw material with plastic resin, add stabilizer, oiling agent etc., forms in tube producer with the method for " moulding " through extrusion process.Because it has light weight, corrosion-resistant, beautiful shape, without features such as bad smell, easy processing, easy constructions, is therefore widely applied in construction engineering.Matched penetration pipe etc. installed by the main tap water supply system pipe arrangement as building construction, draining, exhaust and blowdown sanitary pipe, subsoil drain system, rain pipe and electric wire.But existing plastic tube mostly is single layer structure or simply each plastic pipe layer is made multilayer plastic pipe by molded, and its bearing capacity is low, and structural strength is poor, and actual using process easily produces distortion, there is certain potential safety hazard.
For the bearing capacity solved existing for existing plastic tube is low, the problem of structural strength difference, publication number is that the Chinese patent of CN 203176705 U discloses a kind of plastic tube, it is made up of inner and outer tubes, described interior pipe is nested in outer tube, be provided with fabric layer between described interior pipe and outer tube, described outer tube outer wall be provided with one deck anti-scratch film, the inwall of interior pipe is provided with strengthening rib along tube length direction.This moulds pipe is by increasing the structural strength that strengthening rib improves plastic tube on the inwall of interior pipe, but due to the existence of strengthening rib, because this reducing the interior pipe effective volume of plastic tube, make in actual application, liquid stream flux is hindered, thus reduces Liquid transfer efficiency.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of reinforced plastic pipe.Thus when ensureing that plastic tube effective volume adds the structural strength of plastic tube constant, reduce plastic tube potential safety hazard in use.
The utility model is achieved by following technical solution.
A kind of reinforced plastic pipe, comprise outer body and be arranged at the internal layer body of outer tubular body, be provided with reinforced layer between described internal layer body and outer body, be evenly arranged some stiffening ribs at the outer surface of internal layer body, the length of described stiffening rib and the length of internal layer body match.
Described reinforced layer is formed by braided steel wire.Wrapped on inner tube surface by Steel Wire Braid reticular structure, and be adhesively fixed at steel wire netted struc-ture injection sealer, there is good stiffening effect and sealability.
Described stiffening rib is that semi-cylindrical is fixed on inner tube external surface.
Described stiffening rib and internal layer body as a whole.
The quantity of described stiffening rib is 3 ~ 12.
The quantity of described stiffening rib is 6,
The beneficial effects of the utility model are:
Compared with prior art, the utility model, owing to stiffening rib to be arranged on the outer surface of interior pipe, therefore can not internally to be crossed fluid space and impacts by pipe, can not reduce liquid communication volume, prevents plastic tube from conveying liquid process, producing blocking; Because reinforced layer adopts braided steel wire to reticulate structure, therefore considerably increase the structural strength of plastic tube, the overall performance of plastic tube is greatly improved.The utility model structure is simple, is convenient to manufacture, and has good Social benefit and economic benefit, can in engineering construction technical field wide popularization and application.

Embodiment.
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, a kind of reinforced plastic pipe described in the utility model, comprise outer body 2 and be arranged at the internal layer body 1 of outer body 2 inside, reinforced layer 3 is provided with between described internal layer body 1 and outer body 2, be evenly arranged some stiffening ribs 11 at the outer surface of internal layer body 1, the length of described stiffening rib 11 and the length of internal layer body 1 match.Adopt the technical program, by arranging stiffening rib 11 at internal layer body 1 outer surface, being strengthened the structural strength of whole plastic tube in conjunction with reinforced layer 3 by stiffening rib 11, considerably increasing the bearing capacity of plastic tube; Because stiffening rib 11 is the outer surfaces being arranged on internal layer body 1, therefore can not change the cavity volume of plastic tube, the discharge value of pipe can not be reduced, and pipe in use not easily produce blocking; Simultaneously because stiffening rib 11 is between reinforced layer 3 and internal layer body 1, therefore connection function is played to reinforced layer 3, can prevent reinforced layer 3 from producing with internal layer body 1 surface and depart from, increase plastic tube overall performance further.
Described reinforced layer 3 is formed by braided steel wire.Wrapped at internal layer body 1 on the surface by Steel Wire Braid reticular structure, and be adhesively fixed at steel wire netted struc-ture injection sealer, there is good stiffening effect and sealability.
Described stiffening rib 11 is fixed on internal layer body 1 outer surface for semi-cylindrical.
Described stiffening rib 11 is as a whole with internal layer body 1.Adopt integral molded plastic man-hour adding.
The quantity of described stiffening rib 11 is 3 ~ 12.
The technical program preferentially selects the quantity of stiffening rib 11 to be 6, through facts have proved, adopts 6 stiffening ribs can meet the Structural strength calls of plastic tube, saves material again, economical and practical.
