Abstract

The invention discloses a high-impact-resistance PE (polyethylene) pipe component which comprises an outer pipe and an inner pipe, wherein a plurality of supporting pieces are arranged on the inner wall of the outer pipe, the supporting pieces are uniformly distributed along the circular pipe wall of the outer pipe in an annular array, the supporting pieces are trapezoidal in shape, the lower bottoms of the trapezoidal supporting pieces are connected with the inner wall of the outer pipe, inserting grooves are formed in the upper bottoms of the trapezoidal supporting pieces, inserting blocks matched with the inserting grooves are arranged on the outer wall of the inner pipe, the outer pipe and the inner pipe are connected in a matched inserting mode through the inserting grooves and the inserting blocks, a flow guide supporting piece is arranged inside the inner pipe, the flow guide supporting piece comprises 1 pair of mutually vertical spiral blades, and flow guide holes are formed in the blades. The invention adopts a structure of combining the inner pipe and the outer pipe, the supporting piece is arranged between the inner pipe and the outer pipe, the impact resistance effect is good, the inner pipe and the outer pipe adopt a detachable structure, when the outer pipe is corroded, the outer pipe can be replaced, and the service life of the pipe is prolonged.

Description

PE tubular product component that high impact resistance

Technical Field

The invention relates to a high-impact-resistance PE pipe component.

Background

PE, an acronym for Polyethylene (Polyethylene of stranded temperature resistance), generally has an application range of a PE pipe water supply pipeline lower than 40 ℃, and cannot be used for a hot water conveying pipeline. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the micro-thin section is semitransparent to a certain degree. PE has excellent resistance to most domestic and industrial chemicals.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a PE pipe component with high impact resistance.

The utility model provides a PE tubular product component that high impact resistance, includes outer tube and inner tube, is equipped with a plurality of support piece on the inner wall of outer tube, and support piece is annular array evenly distributed along the circular pipe wall of outer tube, support piece's shape be trapezoidal, trapezoidal support piece go to the bottom and link to each other with the inner wall of outer tube, be equipped with the slot on trapezoidal support piece's the upper base, be equipped with the inserted block that matches with the slot on the outer wall of inner tube, the outer tube links to each other with the mode that the inserted block cooperation was pegged graft through the slot with the inner tube, the inside of inner tube is equipped with the water conservancy diversion backing sheet, the water conservancy diversion backing sheet include 1 to mutually perpendicular's spiral blade, be equipped with the water conservancy diversion hole on the blade.

As a further improvement, the cross section of the insertion block is in a T shape, and the shape of the slot is matched with that of the insertion block.

As a further improvement, the outer circle of the inner pipe is tangent to the upper bottom of the trapezoidal support.

As a further improvement, the number of the supporting pieces is 15-18.

As a further improvement, the connecting mode of the supporting piece and the outer pipe is injection molding and integral molding.

As a further improvement, the connection mode of the insert block and the inner pipe is injection molding and integral molding.

Has the advantages that:

the invention has smart design, adopts a structure combining the inner pipe and the outer pipe, is provided with the support piece between the inner pipe and the outer pipe, has good impact resistance effect, adopts a detachable structure for the inner pipe and the outer pipe, can replace the outer pipe when the outer pipe is corroded, prolongs the service life of the pipe, and is also provided with the flow guide support piece inside the inner pipe, thereby not only supporting the inner pipe, enhancing the impact resistance, but also playing a role in flow guide.

FIG. 1 is a schematic cross-sectional view of a high impact resistance PE pipe member;

FIG. 2 is an enlarged view of a portion of FIG. 1;

1. the outer pipe 2, the inner pipe 3, the supporting piece 4, the diversion supporting piece 5, the diversion hole 6 and the insert block.

Detailed Description

For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.

As shown in fig. 1-2, a high impact resistance PE pipe member includes an outer pipe 1 of an oil cylinder mounting plate, an inner pipe 2, a support member 3, a flow guide support sheet 4, a flow guide hole 5, and an insert block 6.

The cross section of the insertion block is T-shaped, and the shape of the slot is matched with that of the insertion block.

Wherein, the excircle of inner tube be tangent with trapezoidal support piece's upper bottom.

Wherein, the number of the supporting pieces is 15-18.

The connecting mode of the supporting piece and the outer pipe is injection molding and integral molding.

The connecting mode of the insert block and the inner pipe is injection molding and integral molding.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
