The utility model discloses in the pipe wall of plastic pipe body, flat form net twine interweaves the winding back, and the whole thickness of the point of interweaving and the dictyosome diminishes, and the apparent fibre mesh buckle of plastic pipe is little, and the body is mellow and graceful pleasing to the eye, and the inside and outside plastic layer of fibre mesh combines closely firmly, long service life, and the body coefficient of friction each other is low, convenient to use. The utility model discloses the transport of fluid among mainly used industrial and agricultural production and daily life has withstand voltage concurrently and characteristics such as pleasing to the eye.

Description

Special-shaped fiber reinforced plastic hose

Technical Field

The utility model belongs to the technical field of the plastic hose, specifically relate to a be equipped with reinforced fiber net's withstand voltage plastic hose in the body.

Background

PVC and other plastic hoses are used as fluid conveying pipelines and widely applied to the fields of industrial and agricultural production, daily life of people and the like. The fluid is pressurized for long distance, lifting transportation or spraying, which requires a certain pressure resistance of the plastic hose. In order to improve the compressive strength of the plastic hose, a fiber mesh is usually disposed in the plastic hose, and the compressive strength of the hose body is adjusted by adjusting the strength of the fiber mesh. Generally, when the material of the mesh wire is constant, the thicker the mesh wire is, the higher the tensile strength is, and the higher the pressure resistance of the pipe body is. Therefore, in the prior art, in order to obtain a plastic hose with high compressive strength, a thick mesh wire is used for winding a fiber mesh. The fibre web generally includes warp and weft, and the monomer net twine of current fibre web is circular line, and these thicker circular line bodies interweave in the pipe body wall, and plastic hose takes shape back its surface and presents netted unsmooth line, and the net twine is thicker moreover, and the reticulation is unsmooth more obvious, not only influences body outward appearance and body ectonexine bonding strength, and body coefficient of friction is high moreover, is unfavorable for daily use.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a fiber reinforcement plastic hose that compressive strength is high, and the body outward appearance is level and smooth and long service life.

In order to solve the technical problem, the utility model discloses a plastic pipe body with establish at this internal fibre web of pipe, its structural feature is the net twine of fibre web includes flat line.

The flat wires of the fiber net are formed by independent wire bodies in parallel.

The fiber net comprises warp and weft which is wound in a two-way mode, the weft is flat wires, the flat weft is parallel double-wire bodies, and each wire body is a folded wire.

After the structure is adopted, the flat net wires are interwoven and wound into the fiber net in the pipe wall of the plastic pipe body, the interweaving points and the whole thickness of the net body become small, and the net body is smooth; after the plastic pipe is formed, the reticular concave-convex grains on the outer surface of the plastic pipe are small, the surface of the pipe body is round and attractive, the inner plastic layer and the outer plastic layer of the fiber net are tightly and firmly combined, the service life is long, the friction coefficient of the pipe body is low, and the plastic pipe is convenient to use daily. When the thickness of the net lines needs to be adjusted so as to obtain the plastic hose with higher compressive strength, the obvious net line bulges can not appear on the outer surface of the hose body.

Drawings

The invention is further described with reference to the following figures and examples:

FIG. 1 is a partial cross-sectional view of the present invention;

FIG. 2 is a schematic view of a portion of a fiber-reinforced web of the present invention;

FIG. 3 is an enlarged schematic view of the fiber reinforced mesh of the present invention;

fig. 4 is an enlarged schematic view of a cross section of a mesh wire of the fiber reinforced mesh of the present invention.

In the figure: 1. the plastic pipe comprises a plastic pipe body, 11, an inner pipe layer, 12, an outer pipe layer, 2, a fiber reinforced mesh, 21, warp threads, 22, weft threads, 22a, a first line body, 22b and a second line body.

Detailed Description

Referring to fig. 1 to 4, the profiled fiber reinforced PVC plastic hose includes a PVC plastic pipe body 1 and a fiber reinforced mesh 2 disposed in the pipe body wall and tightly combined therewith. In the embodiment shown in the figures, the fibre-reinforced web 2 comprises 4-6 warp threads 21 and a weft thread 22 wound in both directions, the weft thread 22 being in the form of a flat wire. In this embodiment, the flat weft is a double-thread body, which is composed of a first thread body 22a and a second thread body 22 b; each line body is a folded line woven by filamentous fibers, two independent line bodies are connected side by side to form a flat double line body, and the flat double line body is spirally wound and woven to form a fiber net when a plastic pipe body is extruded. The fiber reinforced net 2 can also be wound by parallel three threads, the compressive strength of the hose is improved, but the appearance smoothness and the combination degree of the inner and outer glue layers of the fiber reinforced net 2 are not influenced. The net twine of fibre reinforced net 2 adopts flat line body, and 2 net twine interweave points thickness of fibre reinforced net is little, and the fibre net is whole smooth-going, and after the plastic pipe takes shape, its apparent netted raised grain is little, and the body surface is mellow and beautiful, and the inside and outside plastic layer of fibre net combines closely firmly, long service life, and the body coefficient of friction each other is low, the daily use of being convenient for. When the thickness of the net lines needs to be adjusted so as to obtain the plastic hose with higher compressive strength, the obvious net line bulges can not appear on the outer surface of the hose body.
