Description
Technical field
The utility model relates to a kind of novel plastic-steel low pressure water transportation pipe.
Background technique
At present, the application of aqueduct more and more widely, its demand also constantly increases.Because the demand of society continues to increase, the requirement of product using effect is also improved constantly.
But using more now is a carat pipe, and along with the raising of the development of society, science and technology, the people pursuit to high quality of products, carat pipe initial quality can not satisfy people's needs gradually, and its deficiency has embodied gradually.
Consumable quantity is big when at first, producing from producer surface analysis carat pipe; As shown in Figure 1, the structure of carat pipe is to be made of jointly inner tube 11 and the bellows 12 and the outer field plastic layer 13 that twine on it, need a large amount of plastic cement clad surface during the moulding of carat pipe, so just increased the consumption of plastic cement, and require to increase inner wall thickness for reaching certain ring stiffness, cause serious consumption waste, increased cost of production, influenced economic benefit greatly.
Secondly, from its structure and using effect analysis, the outer wall of carat pipe is that the bellows by plastic components is entwined, so just cause the ring stiffness of carat pipe lower, have a strong impact on its using effect, make its radial load not reach the level that requires, thereby lose favourable use market.
At last, from long-range development, the working life of carat pipe is not high, its structure has had a strong impact on the transportation of tubing, and carat Guan Rong is easy to generate distortion owing to ring stiffness is lower when transportation, is unfavorable for installing and using of tubing, also can have a strong impact on the working life of tubing to influencing its function.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of novel plastic-steel low pressure water transportation pipe, and not only consumptive material is little, and cost is low, manufacturing efficiency height, and long service life.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of novel plastic-steel low pressure water transportation pipe, described conduit pipe comprises at least one conduit pipe unit, this conduit pipe unit comprises the tubing internal layer of hollow and is coated on the tubing skin of this tubing internal layer periphery that described tubing skin is wound in described tubing internal layer periphery by outer section bar spiral and forms; Vertical its outer side surface stretches out and forms some convex tendons on the outer side surface of described outer section bar, is embedded with steel band in this each convex tendon; One edge of the outer side surface of described outer section bar extends and then stretches out and form a bonding limit to parallel outer side surface direction that should the skin section bar to outer side surface direction that vertically should the skin section bar earlier, when described outer section bar screw is wound in described tubing internal layer periphery this bonding limit be covered in adjacent and be wound in described outer section bar on the described tubing internal layer with respect to the another side on its bonding limit along last, and the another side of this bonding limit and described outer section bar along between be provided with adhesive glue and make the two formation one that bonds; The tubing internal layer of described conduit pipe one end and the outer field radius of tubing form the interface end of ccontaining this conduit pipe unit the other end respectively greater than the radius of these other parts of conduit pipe; Be positioned on the tubing internal layer of this interface end and be embedded with electric heating wire, stretch out described interface end after other is provided with two leads and described electric heating wire is communicated with.
As further improvement of the utility model, described convex tendon parallel interval is located on the described outer section bar, and this convex tendon is consistent with the winding direction of described outer section bar.
As further improvement of the utility model, described steel band is perpendicular to described outer section bar outer side surface.
As further improvement of the utility model, described conduit pipe unit conduit pipe does not have outer section bar to cover with respect to the other end periphery of its interface end.
The beneficial effects of the utility model are:
At first, compare with an existing carat pipe, novel plastic-steel low pressure water transportation pipe consumptive material is little, and cost is low.Novel conduit pipe adopts the mode that section bar twines to produce, so just can reduce the outer field wall thickness of tubing, use with reality by experiment and show, novel tube can reduce the wall thickness of 2-3 millimeter and not influence the use of tubing at all, save raw material greatly for the production of conduit pipe, increased the economic benefit of product;
Secondly, the ring stiffness of this novel tube has obtained improving greatly, owing in tubing, used the steel band section bar, make the ring stiffness of novel tube promote 30%-50% on the original basis, can realize the low pressure conduit conveying of 0.2-0.4mPa, outer layer ring rigidity can be applicable to specifications such as SN8, SN10, SN12.6, SN16.Make its radially the bearing load ability significant raising has been arranged, can be applicable to the pipework of requirements at the higher level, for tubing wins more wide application market;
At last, the working life of novel tube is more permanent, can be used in more complicated and bad working environment, owing to increased the steel band section bar in the novel tube, abrasion resistance, anti-pressure ability, yield strength and the impact resistance of tubing have been increased, make tubing be difficult for producing distortion when transportation and installation, it is more convenient to use, and working life is more permanent.
