Abstract
The utility model discloses a light flexible rubber tube which can rapidly convey particles, powdered substance or fluid mediums and gas mediums under high pressure. The utility model comprises an inner rubber layer, an enhancement layer and an outer rubber layer. The utility model is mainly technically characterized in that the enhancement layer is formed by sulfurizing a bare tube two times and processing and sticking a layer of circular fabric of polyester fibre with high intensity and low extension and the seamless inner rubber layer and the seamless outer rubber layer which are formed by squeezing, and each length is 10 metres-50 metres. The utility model has the advantages of simple structure, easy manufacture, light weight, convenient operation and soft texture. The consumed material is 8-10% of the rubberized fabric hose, the pressurization strength is 2-3 times of the rubberized fabric hose, and the light flexible rubber tube can be folded and wrapped.
Description
The utility model sebific duct is to belong to a kind of flexible light instrument of carrying particle, powder-shaped matter or liquid gas medium under high pressure fast.
Before the utility model, existing technology is: carry particle, powder-shaped matter or the employed instrument of liquid gas medium, generally be fabric hose.It is made up of inner glue layer, enhancement layer, outer glue-line.This sebific duct, because its enhancement layer, adopting yarn fabric such as cotton fibre is main material,, forms in kettle cure in the centre of inside and outside glue-line through the calendering looping.So the sebific duct of making can use under normal pressure, use under the high pressure, the easy explosion of body, very dangerous.
In order to address this problem, common way is: increase the enhancing number of plies of sebific duct or twine the layer of metal helix on the outer surface of sebific duct, improve the compressive strength of fabric hose.Like this, it is the manufacturing process complexity not only, the labor intensity height, manufacturing efficiency is low, it is many to consume material, and thickness of pipe wall, heaviness, body hard, give
Fortune is used and is brought many difficulties.
Through preliminary search, and do not find same technical characteristics is arranged, so the utility model is different from prior art with the utility model.
The purpose of this utility model will be improved prior art exactly, and the polyester fibre ply yarn braided fabric that a kind of high-strength flatness is provided is the flexible light sebific duct of enhancement layer.It not only can carry particle, powder-shaped matter or liquid gas medium fast under high pressure.And simple in structure, to make easily, labor intensity is low, the manufacturing efficiency height, it is few to consume material.Simultaneously tube wall is thin, in light weight, quality is soft, can fold and circumnutate,
Fortune is used easily.
The light sebific duct of flexibility of the present utility model, its major technique feature is: it is formed hollow garden cartridge type by inner glue layer, enhancement layer, outer glue-line, the soft rubber product that can fold the black, green or other look that circumnutate.
It is characterized in that: the enhancing series of strata adopt the fibrous braid of the low elongation of high strength, and processing is bonded in the centre of inner glue layer and outer glue-line, and the naked pipe sulfuration forms.The fibrous braid that is adopted weaves on the loom of garden with polyester fibre ply yarn.Inner glue layer, outer glue-line are to form with pushing behind the elastomeric compound heat refining, in cold feed extruder, and it contains natural rubber and synthetic rubber and other rubber chemicals.Process for making is: the seamless outer glue-line extruding is come out after hot blast semi-cure typing, applies layer of adhesive, penetrate the inside of polyester fibre braided fabric, in pipe, after the sulfuration of feeding steam naked pipe, turn over pipe and penetrate seamless inner glue layer more then, feed steam, the naked pipe sulfuration forms.
The light sebific duct of flexibility of the present utility model, it compared with the prior art because enhancement layer adopts the polyester fibre braided fabric of the low elongation of high strength, bonding with the inside and outside glue-line processing that extruding forms, twice naked pipe sulfuration forms.So simple in structure, easy to manufacture, consuming material is 8～10% of folder Song sebific duct, compressive strength is 2～3 times of fabric hose, and weight is special light, and the quality softness can fold and circumnutates,
Fortune is used easily.
Accompanying drawing is the sectional drawing according to the flexible light sebific duct that the utility model proposes.
1. inner glue layers among the figure
2. enhancement layers among the figure
3. outer glue-lines among the figure
Details are as follows for most preferred embodiment:
Inner glue layer among the figure (1), 0.7 to 1.5 millimeter of outer glue-line (3) wall thickness, 23 to 152 millimeters of inner diameters, 10 to 100 meters of length.Used raw material select to have good oil resistant, heat-resisting, acid resistant alkali, high natural rubber or the synthetic rubber of physical and chemical performance such as wear-resisting, ageing-resistant, or natural rubber and synthetic rubber and usefulness, and dose other rubber chemicals.Its preparation process is: plasticate on rubber mixing machine earlier, then carry out mixing.Heat refining cuts out adhesive tape during use, and the condition of heat refining is: the rubber mixing machine capacity is about 45 kilograms, and the roller temperature is preliminary roller 65 degree, back roller is 55 degree, knit time 6 to 10 minutes, the adhesive tape behind the heat refining are sent into φ 90 vacuum cold feed extruders, are squeezed into the desired seamless inside and outside glue-line of above-mentioned specification.
Enhancement layer among the figure (2), 0.8 to 1.5 millimeter of wall thickness, 25 to 152 millimeters of inner diameters, 10 to 100 meters of length.Used raw material are polyester fibre.Preparation process is polyester fibre plying back to be woven to form earlier on the loom of garden.
Its process for making is to realize like this, earlier figure China and foreign countries glue-line (3), be placed on the hot blast semi-cure devices of 150 to 350 degree after the typing, apply layer of adhesive A-2, penetrate the inside of enhancement layer among the figure (2), on vulcanization plant, feed the steam of 145 degree in the pipe, naked pipe sulfuration 10 to 50 minutes to 175 degree, then pipe is turned over from inside to outside, penetrate inner glue layer (1) among the figure after hot blast semi-cure typing again, press said temperature and time, the naked pipe sulfuration forms.
This sebific duct length is 10 to 50 meters/root, can reach more than 50 meters if improve vulcanization plant, and working pressure is 13 to 20 kilograms/cm
2, bursting pressure is 40 to 50 kilograms/cm
2, referential weight 150 to 400 gram/rice can use to the scope of positive 150 degree at negative 50 degree.Be suitable for departments such as seagoing vessel, industrial or agricultural, communications and transportation, hydraulic engineering, building, be specially adapted to the national defense and military field operations and under high pressure, carry particle powder-shaped matter and water, acid, alkali, oils or liquid gas mediums such as steam, wind fast.
