Abstract

The utility model provides a compound PE pipe of three-layer, its characterized in that: outer, anti-pressure layer and the inlayer that sets up including the stack, the outer ABS material that uses antifriction and easily dyeing, anti-pressure layer includes two-layer just, the spiral winding wire netting of anti-, the inlayer uses high density polyethylene plastics, still including setting up tube head and the pipe tail at both ends, the corrugate that has the barb is set to on the surface of tube head, the pipe tail set up with tube head surface matched with internal surface, the length of tube head equals pipe tail length. Have and use tube head and the cooperation of tube tail bayonet type for it is more convenient to connect and subsequent hot melt, and the tube head does not take the resistance to compression layer, and the tube tail area resistance to compression wire netting makes the effect of connecting more fastening.

Description

Three-layer composite PE pipe

Technical Field

The utility model relates to a compound tub of technical field especially relates to a compound PE pipe of three-layer.

Background

In the existing composite pipe, steel wires which are wound in a forward and reverse spiral mode are used in the middle layer of the pipe to improve the strength of the pipe, but the pipe is connected with the two pipes in a hot melting mode mostly, but the connection mode is too single, so that the connection efficiency is low, and the connection is not tight enough.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a compound PE pipe of three-layer can block tube head and tube head that the pipe tail contains just, the technological means on antiwind iron wire layer for the polyethylene material pipe tail through setting up, has solved the intensity of guaranteeing promptly tubular product and has improved the connection efficiency and the stability problem of pipe again.

In order to solve the technical problem, the utility model discloses specifically adopt following technical scheme:

the utility model provides a compound PE pipe of three-layer, includes skin, compressive layer and the inlayer that the stack set up, the outer ABS material that uses antifriction and easy dyeing, the compressive layer includes two-layer just, the intertwine wire netting of anti-spiral, the inlayer uses high density polyethylene plastics, still including setting up tube head and the pipe tail at both ends, the corrugate that has the barb is set to on the surface of tube head, the pipe tail set up with tube head surface matched with internal surface, the length of tube head equals tube tail length.

Compared with the prior art, the utility model discloses following beneficial effect has:

use tube head and the cooperation of the income formula of pipe tail card for it is more convenient to connect and subsequent hot melt, and the tube head does not take the resistance to compression layer, and the pipe tail area resistance to compression wire netting makes to connect more tightly.

in the figure: 1. an outer layer; 2. a pressure resistant layer; 3. an inner layer; 4. a pipe head; 5. and (4) pipe tail.

Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

The utility model provides a compound PE of three-layer pipe, includes outer 1, resistance to compression layer 2 and the inlayer 3 that the stack set up, outer 1 uses antifriction and the easy ABS material that dyes, resistance to compression layer 2 includes two-layer just, the spiral winding's wire netting that turns over, inlayer 3 uses high density polyethylene plastics, still including setting up tube head 4 and the pipe tail 5 at both ends, the corrugate that has the barb is set to on the surface of tube head 4, pipe tail 5 set up with 4 surface matched with internal surfaces of tube head, the length of tube head 4 equals 5 length of pipe tail. Processing is man-hour, earlier processing obtains inlayer 3, then just on inlayer 3, two-layer wire netting of reverse spiral winding, increase the intensity of pipe, because the ABS material of outer 1 use, consequently compare with the outer easier dyeing of polyethylene and difficult fracture, use compressive layer 2 to improve the intensity of pipe, tube head 4 and tube tail 5's length equals, can insert whole tube head 4 to tube tail 5 in, because tube head 4 surface area barb, so can inseparable blocking, reuse the mode of hot melt with tube head 4 and the inseparable connection of official tail 5.

Furthermore, the tube head 4 is uniformly provided with four long grooves on the circumferential surface. The tube head 4 is provided with a long groove to facilitate the insertion of the tube head 4 into the tube end 5 without damaging the tube head 4 or the tube end 5.

Further, the cross section diameter of the pipe head 4 is smaller than that of the outer ring of the inner layer 3. Like this the material of tube head 4 is high density polyethylene plastics, not only conveniently inserts, and convenient processing, and the pipe tail 5 then contains anti-pressure layer 3 for the junction of tube head 4 and pipe tail 5 is firm, has increased the stability of joint.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
