Utility model content
The utility model provides, and the technical problem to be solved is that traditional PVC bellows impact resistance is poor, crushing resistance
Difference is more easily broken off using rear stress for a long time, and refractory ability is poor.
The technical solution that the utility model solves above-mentioned technical problem is as follows: tri- wall bellows of fibrage PVC, including pipe
Body, the tube wall are provided with enhancement layer, and the enhancement layer includes to form the fiber of reticular structure in the tube wall
Item, the ribbon include metal fiber wire and glass fiber, and the metal fiber wire and the glass fiber are mutual
Cross-lapping forms the ribbon, and winding is provided with spiral helicine small corrugated pipe, institute between the enhancement layer and the tube body
Stating small corrugated pipe is hollow structure, and matcoveredn is arranged in the enhancement layer outer wall.
The beneficial effects of the utility model are: a kind of tri- wall bellows of fibrage PVC, including tube body are provided, outside tube body
Wall is provided with enhancement layer, and enhancement layer includes to form the ribbon of reticular structure in tube wall, and ribbon includes metal fibre
Tie up silk and glass fiber, metal fiber wire and the glass fiber overlap joint that intersects form ribbon, and glass fibre has exhausted
The characteristics of edge is good, heat resistance is strong, erosion resistance is good, high mechanical strength, but the disadvantage is that property is crisp, wearability is poor, and metal is fine
It ties up its compression strength, tensile strength, bending strength, impact strength, toughness, impact flexibility etc. to have excellent performance, with glass fibre energy
Preferable complementation is formed, therefore, metal fiber wire and glass fiber elder generation cross winding are formed into ribbon, so that ribbon has
There is the advantages of the two, and form reticular structure in tube wall, form protective layer, can effectively enhance the impact resistance of tube body, resist
Pressure property, the integration capabilities such as ductility, winding is provided with spiral helicine small corrugated pipe between enhancement layer and tube body, during small corrugated pipe is
Hollow structure, deformation occurs for small corrugated pipe when by external force, is effective against impact, further increases resistance to compression, impact resistance, increases
Strong layer outer wall is additionally provided with protective layer, and the netted enhancement layer formed to ribbon plays a protective role.
Based on the above technical solution, the utility model can also do following improvement.
Further, hot melt adhesive layer is provided between the enhancement layer and the tube body.
Further, the protective layer includes bitumen layer and rock wool layer.
Further, the tube body is PVC material.
Further, the small corrugated pipe is HDPE material, the junction setting of the small corrugated pipe and the enhancement layer
There is HDPE adhesive layer.
Beneficial effect using above-mentioned further scheme is that overall structure is more firm, is further improved whole ageing-resistant
Ability is also further enhanced for whole refractory ability.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model.
Fig. 2 is the ribbon structural schematic diagram of the utility model.
In figure: 1- tube body, 2- enhancement layer, 3- protective layer, 4- metal fiber wire, 5- glass fiber, 6- ribbon, 7- are small
Bellows.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Tri- wall bellows of fibrage PVC, as shown in Figure 1, 2, including tube body 1,1 outer wall of tube body are provided with enhancement layer
2, the enhancement layer 2 includes to form the ribbon 6 of reticular structure in 1 outer wall of tube body, and the ribbon 6 includes metal
Fiber filament 4 and glass fiber 5, the metal fiber wire 4 and the glass fiber 5 overlap joint that intersects form the fiber
Item 6, winding is provided with spiral helicine small corrugated pipe 7 between the enhancement layer 2 and the tube body 1, and the small corrugated pipe 7 is hollow
Matcoveredn 3 is arranged in structure, 2 outer wall of enhancement layer.
It can be seen from the above, the utility model provides a kind of tri- wall bellows of fibrage PVC, including tube body 1, outside tube body 1
Wall is provided with enhancement layer 2, and enhancement layer 2 includes to form the ribbon 6 of reticular structure in 1 outer wall of tube body, and ribbon 6 includes gold
Belong to fiber filament 4 and glass fiber 5, metal fiber wire 4 and glass fiber 5 overlap joint that intersects form ribbon 6, glass fibers
Dimension has the characteristics that good insulating, heat resistance are strong, erosion resistance is good, high mechanical strength, but the disadvantage is that property is crisp, wearability is poor,
And metallic fiber its compression strength, tensile strength, bending strength, impact strength, toughness, impact flexibility etc. are had excellent performance, with glass
