Technical Field

The invention relates to a pipeline, in particular to a composite expansion pipeline.

Background

Pipes are installed in various fields for discharging fluid substances and the like. However, the existing pipeline is generally made of steel pipes or PVC materials, and due to the integrated fixing structure, when the water pressure is high, bursting is easily caused, so that the service life of the water pipe is reduced, the discharged water pressure is fixed, and the use field is relatively limited; the water pipe buried in the ground is liable to be pressed down by external excavation work, resulting in breakage of the pipe and insufficient safety of the use environment.

Detailed Description

As shown in fig. 1 and 2, the composite expansion pipeline is a pipeline body formed by splicing more than one arc-shaped section 1, the contact surface of each arc-shaped section 1 forms a splicing surface 5, the splicing surfaces 5 of two adjacent arc-shaped sections 1 are connected and sealed through an elastic layer 6, the splicing surfaces 5 of the adjacent arc-shaped sections 1 are fixed through magnetic structure attraction, a drainage channel 3 is formed in the middle of the pipeline body, an elastic inner film layer 2 is bonded on the inner wall of the drainage channel 3, two sides of the elastic inner film layer 2 extend out of two sides of the pipeline body, one side of the elastic inner film layer extends out to connect with a drainage main pipe 4, and the other end of the drainage main pipe 4 is connected with a water source.

Wherein, the contact surface of adjacent segmental arc 1 is the concave convex surface of arc, and one side contact surface of segmental arc 1 is the arc convex surface, and opposite side contact surface is the arc concave surface, through the concave convex surface concatenation contact of arc between the adjacent segmental arc, and the one end embedding of elastic layer bonds in the segmental arc of one side, and the other end embedding bonds in the concatenation face of adjacent segmental arc.

In this embodiment, the magnetic structure is including imbedding in the first magnet lamella 7 of concatenation face one side, and the embedding sets up in the second magnet lamella 8 of concatenation face opposite side, first magnet lamella 7 contacts the actuation mutually with second magnet lamella 8 and fixes, when inside drainage pressure is very big, make it first, the separation can be backed up to the second magnet lamella, this moment, the whole tensile inflation of rete in elastic layer and the elasticity, as shown in fig. 3, whole pipeline main part inflation this moment, external diameter and internal diameter grow simultaneously, inside can increase the emission, effectively prevent bursting of pipeline, in order to deal with the too big condition of drainage pressure, increase life, after stopping the drainage, under the effect of rete in the elasticity, each segmental arc actuation mutually again is fixed, form a pipeline main part.

And when the outside is pressed, one side of the arc-shaped section at the top is pressed downwards to avoid the problem of direct pipeline breakage, so that the pipeline can be effectively used in the ground. And because the elastic inner film layer is arranged, after the pipeline main body is expanded, the water guide of connection with the main drainage pipe can be ensured, the expanded connection drainage of the pipeline main body can be dealt with, and the normal drainage can be realized.

In this embodiment, the elastic inner membrane layer 2 and the elastic layer 6 are both made of elastic rubber materials, the main drainage pipe 4 and the arc-shaped section are both made of hard PVC materials, and one side of the elastic inner membrane layer 2 extends out of the outer wall surface to be bonded and fixed with the inner wall of the main drainage pipe.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
