Description
Technical field
This utility model is related to pipe applications basic field, specially a kind of PVC-U double-wall corrugated pipes.
Background technology
In prior art, PVC tubing is mainly used in the side such as municipal drainage, field irrigation and draining, post and telecommunications circuit
Face, double-wall corrugated pipe, be with Corvic and stabilizer, lubricant etc. after use pressure sintering extrusion molding, be earliest
The plastic pipe being developed and applied.
UPVC pipes resistance to corrosion is strong, low, quality is hard to be easy to bonding, price, but due to having UPVC monomers and adding
Plus agent is oozed out, delivery temperature is only applicable to less than in 45 DEG C of water supply system, it is swollen that people arrange balance generally on corrugated tube
Swollen section improves its comprcssive strength with corrugated expansion joint, prevents the stress that explodes and eliminate, but this expansion joint, compensator are not only
Price is high, complex process, and joint pressure can make pipeline to fixation, install the very big thrust of generation, come to processing and manufacturing
It is difficult.
Utility model content
The purpose of this utility model is to provide a kind of PVC-U double-wall corrugated pipes, to solve to propose in above-mentioned background technology
Problem.
For achieving the above object, this utility model provides following technical scheme：A kind of PVC-U double-wall corrugated pipes, including it is resistance to
Mill layer, body, high tensile plastics and PVC-U dope layers, the body two ends are respectively arranged with bell and spigot joint and grafting connects
Head, body are divided into internal layer and outer layer, and outer layer winding melting welding has corrugated tube, and bellows interior space is provided with steel wire, the high drawing
Strength plastics material is stretched between the internal layer and outer layer of body, the PVC-U dope layers are covered on the inwall of body.
Preferably, the high tensile plastics are respectively together with internal layer and outer layer heat seal.
Preferably, the bell and spigot joint is provided with draw-in groove and annular groove, and draw-in groove and annular groove are mounted on sealing
Circle.
Preferably, the grafting joint is provided with buckle box bulge loop.
Preferably, the corrugated tube is overcoating is stamped wearing layer, and wearing layer is overcoating to be stamped sunscreen layer.
Preferably, the wearing layer is made up of polyurethane elastomer, and sunscreen layer is made up of reflective fiber, and the sunscreen layer is led to
Cross the mode that adhesive pastes to be attached on wearing layer.
Compared with prior art, beneficial aspects of the present utility model are：The novel PVC-U double-wall corrugated pipes, material are new, produce
Product are rational in infrastructure, and high intensity stretched plastic will be internal layer and outer layer heat seal integral, make product strength high, the PVC- covered in body
U dope layers, make product inner wall smooth, and circulation is big, and less scaling, the wearing layer and sunscreen layer of corrugated tube outer covering effectively prolong
Slow outer layer corrugated tube it is aging, increase the service life, card slot type elastic connection way makes product hermeticity strong, and construction quality is obtained
To guarantee, this utility model is highly reliable, and interface not easy to leak, corrosion resistance are strong, and surface is not easy to crack and long service life
Advantage, is adapted to large-scale use.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Refer to Fig. 1-3, a kind of embodiment that this utility model is provided：A kind of PVC-U double-wall corrugated pipes, wearing layer 1,
Including body 8, high tensile plastics 7 and PVC-U dope layers 6,7 two ends of body are respectively arranged with bell and spigot joint 15 and grafting connects
12,7 points of body is internal layer 5 and outer layer 4, and the winding melting welding of outer layer 4 has corrugated tube 9, and 9 inner space of corrugated tube is provided with steel wire 3,
The high tensile plastics 7 are located between the internal layer 5 and outer layer 4 of body 7, and PVC-U dope layers 6 are covered in the inwall of body 8
On, respectively together with 4 heat seal of internal layer 5 and outer layer, bell and spigot joint 15 is provided with draw-in groove 14 to high tensile plastics 7 and annular is recessed
Groove 10, and draw-in groove 14 and annular groove 10 are mounted on sealing ring, grafting joint 12 is provided with 13 box bulge loop 11 of buckle, corrugated tube
9 it is overcoating be stamped wearing layer 1, wearing layer is overcoating to be stamped sunscreen layer 2, and wearing layer 1 is made up of polyurethane elastomer, and sunscreen layer 2 is anti-
Fiber optics are made, and sunscreen layer 2 is attached on wearing layer 1 by way of adhesive is pasted.
