Background technique
At present, flexible tube hoop enhancement layer mainly contains two kinds of structural types.A kind of be hoop enhancement layer by high strength fibre directly braiding be wrapped in that internal lining pipe is outside to be formed, in the process that is wound around braiding, between fiber, meeting is gapped, has potential pressure extrusion structure, has reduced the entire compression power performance of flexible tube.Another kind is that hoop enhancement layer is formed in inside liner outside by flexible resin and the direct wound and solidified of high strength fibre, due to flexible resin and fiber solidify after its hardness larger, bending radius can only be applicable to larger, can not meet hoop enhancement layer synchronize with flexible tube crooked, also easy to crack when crooked.
Summary of the invention
The purpose of this utility model, for solving the deficiency of above-mentioned technology, provides a kind of reasonable in design, simple in structure, easily manufactures the flexible tube hoop enhancement layer seal wire fusion structure that manufacturing efficiency is high.
The technological scheme that the utility model adopts is: a kind of flexible tube hoop enhancement layer seal wire fusion structure, comprise inside liner, internal layer, skin, it is characterized in that internal layer is spirally wound on inside liner, skin is spirally wound on internal layer, outer spiral winding direction and internal layer spiral winding opposite direction, internal layer is comprised of the first compound strip and the second compound strip, in the first compound strip, the second compound strip, be provided with seal wire, skin is comprised of the 3rd compound strip and the 4th compound strip, in the 4th compound strip, there is seal wire, gapped between internal layer and skin;
The first described compound strip, the second compound strip, the 3rd compound strip, the 4th compound strip, by polymer and the rectangular compound strip of fiber formed by extrusion and tension end face, in the first compound strip, the second compound strip, the 4th compound strip, have seal wire, seal wire is on compound strip 1/2 width;
In the first compound strip of described internal layer, seal wire energising hot melt adhesion is spirally wound on inside liner, in the second compound strip, the stack of seal wire energising hot melt adhesion is spirally wound in the first compound strip, and in the second compound strip, seal wire energising hot melt adhesion is in the first compound strip not on 1/2 width of hot melt adhesion;
Described outer field the 3rd compound strip is spirally wound in internal layer the second compound strip, and the 3rd compound strip spiral winding direction is contrary with the second compound strip winding direction, and in the 4th compound strip, the stack of seal wire energising hot melt adhesion is spirally wound in the 3rd compound strip;
The angle of described internal layer spiral winding angle and inside liner axis is 70 °～88 °, and the angle of outer spiral winding angle and inside liner axis is-70 °～-88 °.
The utility model is reasonable in design, simple in structure, easily manufactures, and winding process is simple, manufacturing efficiency is high, can control and adjust winding angle, quantity and the gap of compound strip, nothing fusion between internal layer and skin, between compound strip, can move by relative sliding, the good bending property of flexible tube, intensity is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1, inside liner, 2, internal layer, the 3, first compound strip, the 4, second compound strip, 5, skin, the 6, the 3rd compound strip, the 7, the 4th compound strip, 8, seal wire.
Embodiment
As shown in Figure 1, a kind of flexible tube hoop enhancement layer seal wire fusion structure, comprise inside liner 1, internal layer 2, outer 5, internal layer 2 is spirally wound on inside liner 1, outer 5 are spirally wound on internal layer 2, outer 5 spiral winding directions and internal layer 2 spiral winding opposite directions, its internal layer 1 is comprised of the first compound strip 3 and the second compound strip 4, in the first compound strip 3, the second compound strip 4, be provided with seal wire 8, outer 5 are comprised of the 3rd compound strip 6 and the 4th compound strip 7, in the 4th compound strip 7, have seal wire; Internal layer 2 is spirally wound on inside liner 1, and outer 5 are spirally wound on internal layer 2, and outer 5 spiral winding directions and internal layer 2 spiral winding opposite directions are gapped between internal layer 2 and outer 5.The first compound strip 3, the second compound strip 4, the 3rd compound strip 6, the 4th compound strip 7 are by polymer and fiber formed by extrusion and tension, the end face of compound strip forms rectangle by certain thickness and width, in the first compound strip 3, the second compound strip 4, the 4th compound strip 7, with static wire 8, on compound strip 1/2 width, be provided with seal wire 8.In the first compound strip 3 of internal layer, seal wire 8 energising hot melt adhesions are spirally wound on inside liner 1, in the second compound strip, the stack of seal wire 8 energising hot melt adhesions is wrapped in the first compound strip 3, and in the second compound strip 4, seal wire 8 energising hot melt adhesions are in the first compound strip 3 not on 1/2 width of hot melt adhesion.Outer 5 the 3rd compound strip 6 is spirally wound in internal layer 2 second compound strip 4, the 3rd compound strip 6 spiral winding directions are contrary with the second compound strip 4 winding directions, in the 4th compound strip 7, seal wire 8 energising hot melt adhesion stacks are wrapped in the 3rd compound strip 6, and seal wire 8 energising hot melt adhesion temperature are at 120 ℃～220 ℃.The angle of internal layer 2 spiral winding angles and inside liner 1 axis is 70 °～88 °, and the angle of outer 5 spiral winding angles and inside liner 1 axis is-70 °～-88 °.
