Abstract
The utility model relates to an annular enhancement layer non-fusion structure of a flexible pipe. The annular enhancement layer non-fusion structure comprises a lining layer, an inner layer and an outer layer, and is characterized in that the inner layer is spirally wound on the lining layer, the outer layer is spirally wound on the inner layer, and the spiral winding direction of the outer layer is opposite to that of the inner layer. The annular enhancement layer non-fusion structure is reasonable in design, simple, easy to manufacture, simple in winding process, high in production efficiency, and capable of controlling and adjusting the winding angles, number and gaps of the composite belts, fusion does not exist between layers, the composite belts can relatively move in a sliding mode, and the bending performance of the flexible pipe is good.
Description
Technical field
The utility model relates to the technical field of flexible flexible tube hoop enhancement layer, specifically the non-fusion structure of a kind of flexible tube hoop enhancement layer.
Background technique
At present, flexible tube hoop enhancement layer mainly contains three 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 being wound around the process weaving, between fiber, there is gap, form potential pressure extrusion structure, reduced the entire compression power performance of flexible tube; The 2nd, 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 hardness larger, the bending radius of pipe is larger, easy to crack when crooked, can not meet hoop enhancement layer and synchronize the requirement of bending with flexible tube; The 3rd, the forming strip that hoop enhancement layer is fused by seal wire is wound, can not relative sliding between fused layers, and this structure can be crooked, but bending properties effect is undesirable.
Summary of the invention
The purpose of this utility model, for solving the deficiency of above-mentioned technology, on the basis of original technology, provides a kind of reasonable in design, simple in structure, easily manufactures the non-fusion structure of flexible tube hoop enhancement layer that manufacturing efficiency is high.
The technological scheme that the utility model adopts is: the non-fusion structure of a kind of flexible tube hoop enhancement layer, 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;
Described internal layer is comprised of the first compound strip and the second compound strip, the first compound strip of internal layer is spirally wound on inside liner, the angle of the first compound strip spiral winding angle and inside liner axis is 70 °～88 °, overlapping 1/2 width of the second compound strip and the first compound strip, staggered stack is spirally wound in the first compound strip, the angle of the second compound strip spiral winding angle and inside liner axis is 70 °～88 °, skin is comprised of the 3rd compound strip and the 4th compound strip, the 3rd compound strip reverse acting spiral is wrapped in the second compound strip, the angle of the 3rd compound strip spiral winding angle and inside liner axis is-70 °～-88 °, the 4th compound strip and overlapping 1/2 width of the 3rd compound strip, staggered stack is spirally wound in the 3rd compound strip, the angle of the 4th compound strip spiral winding angle and inside liner axis is-70 °～-88 °,
The end face of the first compound strip of described internal layer, the end face of the second compound strip and outer field the 3rd compound strip, the 4th compound strip such as is at the rectangle.
The utility model is reasonable in design, simple in structure, easily manufactures, and winding process is simple, and manufacturing efficiency is high, can control and adjust winding angle, quantity and the gap of compound strip, and interlayer, without fusion, can move by relative sliding between compound strip, the good bending property of flexible tube.
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.
Embodiment
As shown in Figure 1, the non-fusion structure of a kind of flexible tube hoop enhancement layer, comprises inside liner 1, internal layer 2, skin 5, and internal layer 2 is spirally wound on inside liner 1, and 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 2 is comprised of the first compound strip 3 and the second compound strip 4, the first compound strip of described internal layer 2 is spirally wound on inside liner 1, the angle of the first compound strip 3 spiral winding angles and inside liner 1 axis is 70 °～88 °, the second compound strip 4 and overlapping 1/2 width of the first compound strip 3, staggered stack is spirally wound in the first compound strip 3, the angle of the second compound strip 4 spiral winding angles and inside liner 1 axis is 70 °～88 °, described outer 5 are comprised of the 3rd compound strip 6 and the 4th compound strip 7, outer 5 the 3rd compound strip 6 reverse acting spirals are wrapped in the second compound strip 4, the angle of the 3rd compound strip 6 spiral winding angles and inside liner 1 axis is-70 °～-88 °, the 4th compound strip 7 and overlapping 1/2 width of the 3rd compound strip 6, staggered stack is spirally wound in the 3rd compound strip 6, the angle of the 4th compound strip 7 spiral winding angles and inside liner 1 axis is-70 °～-88 °.The end face of the first compound strip of internal layer, the end face of the second compound strip and outer field the 3rd compound strip, the 4th compound strip such as is at the rectangle.
Because interlayer is without fusion, level and smooth between compound strip, and gapped, slidably move, the good bending property of flexible tube, can realize the bending of small radii.
