Abstract
The utility model discloses a thin-wall flexible pipe, it comprises inner tube, braided tube, coating, adhesive layer jointly. The inner pipe is a rubber pipe, the braided pipe is formed by braiding synthetic fibers, the braided pipe is integrally sleeved on the outer wall of the inner pipe, and the inner pipe and the braided pipe are bonded into a whole through an adhesive layer. The outer wall of the braided tube is coated with a synthetic polymer material with good wear resistance as a coating, and the coating is a protective layer of the braided tube. The thin-wall flexible pipe made of different functional soft materials by layering and compounding has enough compression strength and good flexibility, can be bent at will when in use, can be folded, and is particularly suitable for being used as a high-pressure oil pipe or an air pipe.
Description
Technical field
The utility model relates to a kind of pipeline, and specifically, the utility model relates to a kind of flexible nonmetallic tubing.
Background technique
Rubber pipe is a kind of pipeline with flexibility characteristics, is widely used in industrial or agricultural and other industries.Prior art embeds a certain amount of cellosilk or wire in order to improve the compressive strength of rubber pipe in the rubber tube wall during manufacturing.The rubber pipe compressive strength of this structure and embedded cellosilk or wire amount are proportional within the specific limits, cellosilk that the pipeline that compressive strength is big more is embedded or wire amount are just many more, its tube wall is just thick more, the rubber pipe bending radius is just big more, the flexibility of rubber pipe is just more little, have in addition forfeiture rubber pipe flexibility characteristics.
The model utility content
The utility model is at the flexibility and the unmatched shortcoming of compressive strength of prior art rubber pipe, proposes a kind ofly by the compound thin-walled flexible pipe of the soft material layering of difference in functionality, and this structure tube wall is thin, compressive strength height, arbitrarily bending, the collection of can reeling.
For achieving the above object, the utility model is taked following design proposal:
A kind of thin-walled flexible pipe is made of jointly interior pipe, woven tube, coating, adhesive layer; Pipe is a kind of round rubber pipe in described, be with the woven tube of the size that matches on the outer wall of inner tube, be integral by adhesive layer is bonding between interior pipe and the woven tube, the material of described woven tube is synthetic fiber, the coating of full coat one deck synthesized polymer material on the woven tube outer wall.
Interior pipe in the said structure directly contacts with medium, and the material of interior pipe satisfies mainly that dense structure does not leak, anti-aging, oil resistant, corrosion-resistant requirement, selects ethylene propylene diene rubber or nitrile rubber manufacturing for use.Woven tube forms with the high polyster fibre braiding of tensile strength; woven tube integral body is linked on the outer wall of inner tube; be integral by adhesive layer is bonding between outer wall of inner tube and the woven tube inwall; the compressive strength of pipe in woven tube plays and improves; be brushed with coating on the woven tube outer wall; this coating is the protective layer of woven tube, and the coating material is the good high molecular synthetic material of wear-resisting property.By the compound tube wall of the soft material layering of difference in functionality, bring into play the different characteristics of different materials the biglyyest, the thin-walled flexible pipe tube wall of manufacturing is thin, flexibility is good, compressive strength is high.
The utility model thin-walled flexible pipe compared with prior art has following good effect:
1, flexible good---by the flexible pipe that the multilayer soft material is composited, flexible, collapsible;
2, tube wall is thin---and the tube wall of identical bore pipe only is 1/8～1/5 of a prior art products;
3, in light weight---identical bore pipe, unit weight only are 1/8～1/5 of prior art;
4, cost is low---and use composite, intensity height, materials are few, and the manufacture cost of identical bore pipe only is 1/5～1/3 of a prior art.
Description of drawings
Fig. 1 is the part sectioned view of the utility model thin-walled flexible pipe.
Embodiment
Below with reference to the accompanying drawings shown in and embodiment, the utility model is further described.
A kind of thin-walled flexible pipe is made of jointly interior pipe 1, woven tube 2, coating 3, adhesive layer 4.Pipe 1 pipe that to be the utility model thin-walled flexible pipe directly contact with medium in described, its material satisfy mainly that dense structure does not leak, oil resistant, corrosion-resistant requirement, meet above-mentioned requirements with ethylene propylene diene rubber or nitrile rubber manufacturing.Present embodiment is a kind of bore φ 25mm, and the air duct of compressive strength 7MPa is made interior pipe 1 with ethylene propylene diene rubber, and thickness of pipe wall is 0.5mm.Woven tube 2 is to form with the high polyster fibre braiding of tensile strength, and its internal diameter and interior pipe 1 external diameter match, and thickness of pipe wall is 0.5mm.On interior pipe 1 outer wall, be coated with adhesive layer 4, interior pipe 1 is presented in the woven tube 2.The outer wall coated 3 in woven tube 2 through steam pressurized sulfuration back again becomes the protective layer of woven tube 2 after these coating 3 curing, present embodiment is selected aqueous polyurethane making coatings 3 for use, and it is thick to be 0.3mm.The utility model is brought into play the characteristics of material by the compound thin-walled flexible pipe of the soft material layering of above-mentioned difference in functionality the biglyyest, makes the existing enough compressive strengths of thin-walled flexible pipe, has good flexibility again.Can be arbitrarily crooked, collapsible when reality is used the thin-walled flexible pipe.
