Description

Plastic pipeline

Technical Field

The utility model relates to a plastic conduit technical field, concretely relates to plastic conduit.

Background

The plastic pipeline is an important branch of a plurality of components of chemical building materials, and the application fields of the plastic pipeline are water supply, water drainage, gas, floor heating, electric power communication, agriculture, fire fighting and other fields generally. Among the non-metallic pipelines, the most widely used is plastic pipelines. Plastic pipes are widely classified into two main categories, thermoplastic pipes and thermosetting pipes. The plastic pipe has the main advantages of good corrosion resistance, light weight, convenient forming and easy processing, and has the defects of low strength and poor heat resistance.

In the installation and use process of the plastic pipeline, due to the limited ductility of the plastic pipeline, the pipeline is easy to crack or break under the action of external force vibration or compression deformation, so that the pipeline cannot be normally used.

Disclosure of Invention

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

an inner pipe body;

an outer pipe body;

intermediate level pipeline body set up in between inlayer pipeline body and the outer pipeline body, the surface of intermediate level pipeline body is provided with a plurality of breachs along the circumferencial direction interval, wherein the ductility of intermediate level pipeline body is less than the ductility of inlayer pipeline body and outer pipeline body.

In one possible embodiment, the interlayer pipeline body is made of phenolic resin.

In a possible embodiment, the cross-sectional profile of the notch is a profile opening structure of a "U" shape.

In one possible embodiment, the thickness of the intermediate pipe body is smaller than the thickness of the inner and outer pipe bodies.

In a possible embodiment, the outer pipe body is made of polyethylene, and the inner pipe body is made of polypropylene.

The utility model has the advantages that:

1. the plastic pipeline in the embodiment of the application is provided with the inner pipeline body, the outer pipeline body and the middle pipeline body, wherein a plurality of gaps are formed in the surface of the middle pipeline body at intervals along the circumferential direction, and meanwhile, the ductility of the middle pipeline body is smaller than those of the outer pipeline body and the inner pipeline body; when the pipeline is used, the outer layer pipeline body, the middle layer pipeline body and the inner layer pipeline body are of an integral structure, stress applied to the pipeline in the circumferential direction can act on the outer layer pipeline body, the middle layer pipeline body and the inner layer pipeline body, but the end face of the middle layer pipeline body is provided with a notch, and the ductility of the middle layer pipeline body is smaller than that of the outer layer pipeline body and that of the inner layer pipeline body, so that when the stress is increased to a certain value, the notch on the middle layer pipeline body can be broken, the middle layer pipeline body can be deformed when being broken, partial stress acting on the pipeline can be eliminated, and the service life of the pipeline is prolonged;

2. through being provided with the cross-sectional structure that the cross-section is "U" type with the breach, can be so that the cross-sectional shape of breach is mild relatively, and breach connection area is great, avoids the breach extremely easy fracture when receiving the exogenic action, and then has guaranteed that the breach possesses certain service strength.

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 3, fig. 1 is a schematic perspective view of a plastic pipe in an embodiment of the present application; FIG. 2 is a schematic partial cross-sectional view of a plastic pipe according to an embodiment of the present invention; fig. 3 is a partially enlarged schematic view of a portion a of fig. 1. The embodiment of the application provides a plastic pipeline 100, which comprises an inner pipeline body 103, an outer pipeline body 101 and an intermediate pipeline body 102.

In the embodiment of the present application, the middle-layer pipe body 102 is disposed between the inner-layer pipe body 103 and the outer-layer pipe body 101, the middle-layer pipe body 102, and the inner-layer pipe body 103 constitute an integral pipe structure. The outer surface of the intermediate pipe body 102 is provided with a plurality of notches 104 at intervals in the circumferential direction, wherein the ductility of the intermediate pipe body 102 is smaller than those of the inner pipe body 103 and the outer pipe body 101.

In some embodiments of the present application, the intermediate layer pipe body 102 is made of phenolic resin; the outer pipe body 101 is made of polyethylene, and the inner pipe body 103 is made of polypropylene.

In addition, in order to ensure that external force is applied to the plastic pipeline 100 during use, the middle-layer pipeline body 102 can effectively eliminate partial external force, and the service life of the pipeline is prolonged. In the present embodiment, the thickness of the intermediate pipe body 102 is smaller than the thickness of the inner pipe body 103 and the outer pipe body 101. Through setting up the thickness size of intermediate level pipeline body 102 less, can be so that when external force applyed on the pipeline, the service strength of intermediate level pipeline body 102 is lower for the service strength of outer pipeline body 101 and inlayer pipeline body 103, therefore intermediate level pipeline body 102 is the easiest deformation fracture, can eliminate the external force that the part was applyed on the pipeline, prolongs the life of pipeline.

Referring to fig. 2, in the embodiment of the present application, the cross-sectional profile of the notch 104 is a profile opening structure of a "U" shape. Through being provided with breach 104 the cross-sectional structure that the cross-section is "U" type, can be so that the cross-sectional shape of breach 104 is gentle relatively, and breach 104 connection area is great, avoids breach 104 extremely easy fracture when receiving the exogenic action, and then has guaranteed that breach 104 possesses certain service strength.

When the plastic pipeline in the embodiment of the application is used, because outer pipeline body 101, intermediate level pipeline body 102 and inner layer pipeline body 103 are overall structure, the stress exerted on the pipeline circumferential direction can act on the three, but because be provided with breach 104 and its self ductility on its terminal surface of intermediate level pipeline body 102 is less than outer pipeline body 101 and inner layer pipeline body 103, consequently when stress increases to a definite value, breach 104 on intermediate level pipeline body 102 can produce and break, and deformation can be produced when intermediate level pipeline body 102 breaks, and then partial stress that acts on the pipeline can be eliminated, the service life of pipeline is prolonged.

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.
