Abstract
The utility model discloses a high-strength glass fiber reinforced plastic winding pipe and relates to a rigid pipe, wherein the pipe wall is formed by winding glass fiber yarns back and forth; the outer surface of the glass fiber yarns is covered with a resin adhesive layer; and the cross sections of the glass fiber yarns and the resin adhesive layer covered on the outer surface of the glass fiber yarns are flat rectangular. The winding pipe has no gap inside and has compact structure and high strength and rigidity; in addition, the defects of leakage, bursting and breakage in the using process do not occur, and the winding pipe is very practical.
Description
Technical field
The utility model relates to a kind of rigid pipe, relates in particular to a kind of high strength glass steel winding pipe.
Background technique
The relative density of glass fibre reinforced plastic material has only the 1/4-1/5 of carbon steel, but tensile strength is approaching, even surpasses carbon steel, and specific strength can be compared with high-grade alloy steel.At pipeline, high-pressure bottle and in other goods that need alleviate deadweight are used, all has superior efficacy.Glass fibre reinforced plastics is good anticorrosive material, and atmosphere, water and general acid, alkali, salt and multiple oils and solvent are all had resistivity preferably.Be applied to the All aspects of of chemical anticorrosion, replaced carbon steel, stainless steel, timber, non-ferrous metal etc.Glass fibre reinforced plastics is good insulating material, is used for making insulator, still can keep good dielectricity under the high frequency.The glass fibre reinforced plastics thermal conductivity is low, is 1.25～1.67kJ/ (mhk) under the greenhouse, has only 1/100～1/1000 of metal, is good thermoinsulation material.
Numerous premium properties of above-mentioned glass fibre reinforced plastic material are given full play in all kinds of containers and pipeline.For example, the Glass Steel Tube internal surface is smooth, and weight only is 1/4 of same diameter steel pipe, and is with the obvious advantage, both had been subjected to the favor of water undertaking, popular with users again.Wherein, the glass fibre reinforced plastics entwining tube is fast because of its lay material, economy, Master Cost is low and characteristic extensive use such as steady quality, but but there is defective in existing glass fibre reinforced plastics entwining tube.More existing glass fibre reinforced plastics entwining tube adopts the glass fiber yarn of 2400tex, 4800tex, 7600tex, 8400tex to come and go and twines the formation tube wall, and glass fiber yarn is coated with the resin glue-line.Existing glass fiber yarn cross section under nature is circular, diameter is 0.31-0.55mm, because its cross section is circular, so be coated on the cross section of the resin glue-line of glass fiber yarn outer surface also is circular, therefore glass fiber yarn overlaps mutually in coming and going winding process and can form many spaces, the space can increase resin content, reduces glass fiber yarn content relatively, and resin can not be filled up these spaces fully simultaneously.Have a strong impact on the intensity of glass fibre reinforced plastics entwining tube.Make the glass fibre reinforced plastics entwining tube defectives such as seepage, explosion and fracture in use occur.
The model utility content
At the problem that above-mentioned prior art exists, the utility model provides a kind of high strength glass steel winding pipe, and its inside does not have the space, structure is tight, the strength and stiffness height defectives such as seepage, explosion and fracture can not occur in the using process, and is very practical.
The technical solution of the utility model is: a kind of high strength glass steel winding pipe, its tube wall is come and gone to twine by glass fiber yarn and constitutes, the glass fiber yarn outer surface is coated with the resin glue-line, and described glass fiber yarn is flat rectangle with the cross section that is coated on the resin glue-line of its outer surface.
The beneficial effects of the utility model are: because glass fiber yarn is flat rectangle with the cross section that is coated on the resin glue-line of its outer surface in the utility model, so tightly fit in the surface of the resin glue-line of the adjacent outer coating of glass fiber yarn in coming and going winding process, do not have the space.Increased the intensity of tube wall; Rectangular cross section increases 2-3 doubly by the surface of contact between the glass fiber yarn, and structure is tightr.Because the cross section of glass fiber yarn is flat rectangle,, guarantee the humidification of glass fiber yarn in addition, increased the strength and stiffness of glass fibre reinforced plastics entwining tube so the consumption of the tube wall glass fiber yarn of same diameter increases.
Description of drawings
Fig. 1 is existing glass fibre reinforced plastics entwining tube internal structure schematic representation;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the utility model internal structure schematic representation.
Embodiment
As a kind of mode of execution of the present utility model, as shown in Figures 2 and 3, a kind of high strength glass steel winding pipe, its tube wall 5 is come and gone to twine by glass fiber yarn 1 and constitutes, glass fiber yarn 1 outer surface is coated with resin glue-line 2, and described glass fiber yarn 1 is flat rectangle with the cross section that is coated on the resin glue-line 2 of its outer surface.
The internal structure schematic representation of existing glass fibre reinforced plastics entwining tube as shown in Figure 1, the cross section of glass fiber yarn 11 is circular, the cross section of its outside resin glue-line 22 that coats also is circular, there are many spaces 33 between the adjacent glass silvalin 11, resin glue-line 22 can not be filled up these spaces fully, cause the intensity of tube wall not high, be prone to defectives such as seepage, explosion and fracture.
In the present embodiment, cross section is that the glass fiber yarn 1 of flattened rectangular is to make by following technology: all will flood in the resin glue liquid bath before glass fiber yarn 1 twines, allow glass fiber yarn 1 outsourcing be covered with resin glue-line 2, change the Yarn-guiding mouth in resin glue liquid bath outlet port into flat rectangle by cylindrical body, glass fiber yarn 1 is banded through the extrusion-deformation of Yarn-guiding mouth, directly enters winding working procedure.
Described Yarn-guiding mouth adopts corrosion resistant plate to make, and opens the taper rectangular hole on its surface.(quantity in hole by technology fixed) circular glass fiber yarn 1 is squeezed into flat band shape during by Yarn-guiding mouth under the Stetch Wrapping Machine tension.The Yarn-guiding mouth plate is made as two groups, in order to progressively distortion, reduces resistance.
Claims (1)
