Double-layer plastic pipeline

Technical Field

The utility model relates to a plastic conduit product technical field, concretely relates to double-deck plastic conduit.

Background

Plastic tubing is a generic term for pipes made of plastic materials. The plastic pipeline has the characteristics of light dead weight, sanitation, safety, small water flow resistance, energy conservation, metal conservation, improvement on living environment, long service life, safety, convenience and the like, is favored by the pipeline engineering community, and is widely applied to the construction industry, municipal administration, industry and agricultural field such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheaths, industrial fluid conveying, agricultural irrigation and the like.

The plastic pipeline can not be greatly influenced by the change of soil, temperature and humidity, and has stronger chemical resistance; but because the pipeline is made of plastic materials, the strength and the shock resistance are effective. In daily construction and pipeline application occasions, collision or impact on a pipeline is difficult to avoid, so that the plastic pipeline is extremely easy to damage, and therefore, the pipeline structure which is light in weight and can have good impact resistance is very important for providing.

Disclosure of Invention

To the defect that exists among the prior art, the utility model aims to provide a double-deck plastic conduit, it possesses double-deck pipeline structure for this double-deck plastic conduit, and its quality is lighter, and intensity is better, and the setting up of cavity buffer layer makes the pipeline possess better shock-absorbing capacity.

The embodiment of the application provides a double-deck plastic conduit, plastic conduit includes:

an inner tube;

the outer tube, with the inner tube coaxial setting and fixed set up in the inner tube surface, the longitudinal section of outer tube is the wave appearance structure of extending the arrangement in succession along the axial, wherein the outer tube passes through the wave appearance structure on it with be formed with a plurality of hollow buffer layers along the axial arrangement between the inner wall of inner tube.

Further, the hollow buffer layer is filled with a heat insulation material layer or a shock absorption material layer.

Furthermore, one end of the plastic pipeline is formed into a bell mouth structure with the outwardly extending size gradually enlarged, and the other end of the plastic pipeline is formed into a cone mouth structure with the size gradually reduced, wherein the cone mouth structure gradually reduced can be tightly inserted and installed in the inner wall of the bell mouth structure gradually enlarged.

Furthermore, the inner pipe and the outer pipe are made of polyethylene materials.

The utility model has the advantages that:

1. the double-layer plastic pipeline in the embodiment of the application is provided with the inner pipe, the outer pipe and the plurality of hollow buffer layers formed between the outer pipe and the inner wall of the inner pipe, the double-layer plastic pipeline can further improve the strength of the pipeline on the basis of ensuring that the pipeline has light weight, and meanwhile, the hollow buffer layer structure formed between the pipelines can effectively buffer when the pipeline is subjected to external force, so that the damage to the inner pipe is relieved, and the normal use function of the pipeline is further ensured; in addition, the arrangement of the middle buffer layer also has a heat insulation effect to a certain extent;

2. set up to the horn mouth structure of size grow gradually through the one end with the pipeline, the other end sets up to the bell mouth structure that the size reduces gradually, and during two adjacent pipe installations, can closely insert the one end inner chamber of the horn mouth structure of another pipeline with the one end of the bell mouth structure of a pipeline, and then convenient and fast ground realizes the installation work of two pipelines.

Detailed Description

The present invention will be described in further detail with reference to the drawings and the following detailed description.

Referring to fig. 1 to 2, fig. 1 is a schematic perspective view of a double-layer plastic pipe in an embodiment of the present application; fig. 2 is a schematic longitudinal sectional view of the double-layer plastic pipe in the embodiment of the present application. The embodiment of the application provides a double-layer plastic pipeline 100, including inner tube 101 and outer tube 102 (in this embodiment, inner tube 101 and outer tube 102 adopt the polyethylene material to make and form, certainly can also adopt other commonly used pipe materials, not taking as a limit), outer tube 102 sets up with inner tube 101 is coaxial, outer tube 102 sets up at inner tube 101 surface, the longitudinal section of outer tube 102 is the wave appearance structure of extending the arrangement along the axial in succession, wherein outer tube 102 is formed with a plurality of hollow buffer layers 105 along the axial arrangement through between the wave appearance structure on it and inner tube 101 inner wall. Namely, the outer tube 102 has a wave-shaped configuration, and the upward convex portion of the outer tube and the outer wall of the inner tube 101 form a closed hollow structure, i.e., the hollow buffer layer 105 is formed.

The arrangement of the double pipelines can further improve the strength of the pipelines on the basis of ensuring that the pipelines have lighter weight, and meanwhile, the hollow buffer layer 105 structure formed between the pipelines can effectively buffer the pipelines when the pipelines are subjected to external force, so that the damage to the inner pipe 101 is relieved, and the normal use function of the pipelines is further ensured; in addition, the arrangement of the middle buffer layer also has a heat insulation effect to a certain extent.

For some applications where insulation or cushioning is desired, in some embodiments of the present application, hollow cushioning layer 105 is filled with a layer of insulation material (e.g., insulation wool) or a layer of shock absorbing material (e.g., foam).

To facilitate the connection between the pipes, in the embodiment of the present application, one end of the plastic pipe 100 is formed as a flared structure 103 with a gradually expanding size extending outward, and the other end thereof is formed as a tapered structure 104 with a gradually decreasing size, wherein the tapered structure 104 can be tightly inserted and mounted in the inner wall of the flared structure 103. Through the design of the overall dimension of the two ports of the pipeline, the tight fit between the ports of the pipeline is realized, and then the installation work of the two pipelines can be conveniently and rapidly realized.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalent technologies, the present invention is also intended to include such modifications and variations.
