High-pressure-resistant polyethylene pressure pipe

Technical Field

The utility model relates to a tubular product specifically indicates a highly compressed polyethylene pressure tubular product.

Background

At present, metal pipes are generally used for pipelines which need to bear larger pressure or complex load, but the defect that the metal pipes are easy to corrode often causes high operating cost, so that plastic pipeline systems are adopted in a plurality of application fields, but the all-plastic pipes also have obvious defects, such as low strength and low pressure bearing performance. Therefore, a high-pressure-resistant polyethylene pressure pipe is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem and providing a high pressure resistant polyethylene pressure pipe.

In order to achieve the above purpose, the utility model provides a following technical scheme: a high-pressure-resistant polyethylene pressure pipe is characterized by comprising a pipe body and a connecting piece, wherein the pipe body is divided into a PE layer, a rubber layer and a metal net layer; the pipeline body inlayer is the PE layer, set up the rubber layer outside the PE layer, set up the metal mesh layer outside the rubber layer, still be equipped with one deck PE layer outside the metal mesh layer.

Preferably, the PE layer and the rubber layer are formed by co-extrusion; the metal net layer is arranged on the rubber layer after the rubber layer is subjected to injection molding, and the metal net layer is fixed on the rubber layer through the rubber layer and the PE layer.

Preferably, a bonding glue layer is arranged between the two adjacent layers.

Preferably, mounting grooves are formed in two ends of the connecting piece, and electric heating wires are pre-buried in the mounting grooves; the pipeline body is connected with the connecting piece through hot melting welding.

The utility model has the advantages that: the pipeline has simple structure; the rubber layer and the metal net layer are arranged, so that the strength of the pipeline is increased, the pressure bearing performance is enhanced, and the pipeline damage caused by overlarge pressure is avoided; through the setting of connecting piece, increase the fastness of connecting to increase the steadiness and the leakproofness of pipeline junction.

Detailed Description

The following will further describe a high pressure resistant polyethylene pressure pipe according to the present invention with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the high pressure resistant polyethylene pressure pipe of the present embodiment is characterized by comprising a pipe body 1 and a connecting member 3, wherein the pipe body 1 is divided into a PE layer 2, a rubber layer 4 and a metal mesh layer 5; the inner layer of the pipeline body 1 is a PE layer 2, a rubber layer 4 is arranged outside the PE layer 2, a metal mesh layer 5 is arranged outside the rubber layer 4, and a PE layer 2 is arranged outside the metal mesh layer 5; the PE layer 2 and the rubber layer 4 are formed by co-extrusion; the metal mesh layer 5 is arranged on the rubber layer 4 after the rubber layer 4 is subjected to injection molding, and the metal mesh layer 5 is fixed on the rubber layer 4 through the rubber layer 4 and the PE layer 2; a bonding glue layer 6 is arranged between the two adjacent layers; mounting grooves 7 are formed in two ends of the connecting piece 3, and electric heating wires 8 are pre-buried in the mounting grooves 7; the pipeline body 1 is connected with the connecting piece 3 through hot melting welding.

In the manufacturing process of the embodiment, when the pipeline body 1 is co-extruded and formed, the PE layer 2 and the rubber layer 4 are co-extruded and formed, the metal mesh layer 5 is sleeved on the rubber layer 4 after forming, then the PE layer 2 is extruded out of the metal mesh layer 5, and the adhesive layers 6 are co-extruded between the two adjacent layers; cooling and forming to finish the processing of the pipe; when pipeline body 1 is connected with pipeline body 1, at first insert the mounting groove 7 on connecting piece 3 with pipeline body 1 in, then to pre-buried electric heating wire 8 circular telegram in mounting groove 7, make its heating hot melt connecting piece 3 and pipeline body 1 junction, wait to cool off the back, pipeline body and connecting piece are connected and are accomplished.

The utility model has the advantages that the strength and pressure bearing performance of the polyethylene pipe are improved by adding the metal net layer 5 in the polyethylene pipe; due to the arrangement of the rubber layer 4, the rubber layer 4 has certain elasticity and toughness, and the pipe is damaged when bearing excessive pressure or being hit by a heavy object; the metal mesh layer 5 is convenient to be sleeved on the rubber layer 4; by arranging the metal net layer 5 and the rubber layer, the pressure bearing performance and the impact resistance of the pipeline are improved; through pre-buried electric heating wire 8 in connecting piece 3, then make pipeline body 1 and connecting piece 3 pass through hot melt welded connection through electric heating wire 8, increase the stability and the leakproofness of connecting to the erection joint is simple and convenient.

The scope of the present invention is not limited to the above embodiments and their variations. The present invention is not limited to the above embodiments, and other modifications and substitutions may be made by those skilled in the art.
