Abstract
The utility model provides a low permeable fuel flexible pipe. The pipe wall of the low permeable fuel flexible pipe comprises an inner separating layer, a middle lamella, a reinforced layer and an external lamella which are sequentially arranged from interior to exterior, wherein the reinforced layer is formed by a polyester wire or an aramid fiber wire twined round the middle lamella. The low permeable fuel flexible pipe is not only characterized in that the inner separating layer on the pipe wall separates agents crossing through the pipe but also characterized by low permeability, fuel-proof property, better heat-proof property, good low temperature flexibility and high working pressure through cooperating with other layers on the pipe wall.
Description
Technical field
The utility model relates to a kind of low-penetration fuel flexible pipe.
Background technique
In recent years, along with the raising of automobile exhaust emission standard, the also corresponding raising with the gasoline of anti-deterioration property of heat resistance to the motor car engine rubber product requires fuel hose class rubber product must have high-temperature heat-resistance oxidability and the gasoline of anti-deterioration property.State's three emission standards are stipulated at present, the fuel pipe that with gasoline is fuel vehicle requires lower CH (hydrocarbon) permeability, though fuel hose class rubber product has the multi-layer structure of employing form to intercept the fuel oil infiltration at present, but every performance such as permeability is difficult to take into account, and does not often reach relevant standard.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can effectively reduce CH material seepage, and the low-penetration fuel flexible pipe of anti-fuel oil and excellent heat resistance.For this reason, the utility model is by the following technical solutions: its tube wall is made up of interior barrier layer, mesoglea, enhancement layer and outer glue-line, barrier layer, mesoglea, enhancement layer and outer glue-line set gradually from inside to outside in described, and described enhancement layer is constituted by being wrapped in mesoglea outer polyester line or aramid line.By above technological scheme, the interior barrier layer of the utility model tube wall plays iris action to the medium that passes through in pipe, and it is collaborative by the combination of other each layer of tube wall, make the utility model not only realize hyposmosis, anti-fuel oil, and has stronger heat resistance, low-temperature pliability is good, the working pressure height.
The utility model glue-line outside also can be provided with Stainless Steel Wire braiding jacket layer outward.Crushing resistance and wear-resisting property with further increase flexible pipe.
Description of drawings
Fig. 1 cuts open figure for embodiment that the utility model provides 1 office.
Fig. 2 is embodiment that the utility model provides 2 cross-sectional view.
Embodiment
With reference to accompanying drawing 1.This figure is the structural representation of embodiment 1 strip off layer by layer.Tube wall of the present utility model is made up of interior barrier layer 1, mesoglea 2, enhancement layer 3 and outer glue-line 4, barrier layer 1, mesoglea 2, enhancement layer 3 and outer glue-line 4 set gradually from inside to outside in described, and enhancement layer 3 is constituted by being wrapped in mesoglea 2 outer polyester line or aramid line.
It is material that interior barrier layer 1 can adopt ternary fluororubber.The ternary fluororubber (fluorine content〉70%) of recommending to select for use the bisphenol A vulcanizing system when implementing is as interior barrier material, and control its thickness about 0.25-0.35mm, pass through the multi-layer structure of fuel hose 4-5 layer again, can effectively reduce the seepage of CH material, and can guarantee that product has excellent fuel resistance and heat resistance.
Mesoglea 2 can be selected chlorohydrin rubber for use, add in the chlorohydrin rubber high activity calcium hydroxide as bonding agent after, the bonding strength of chlorohydrin rubber and interior barrier layer 1 can reach 1.5KN/m.Enhancement layer 3 plays skeleton function, and it selects polyester line or aramid line for use, through twining processing, can strengthen the withstand voltage properties of flexible pipe.Described outer glue-line 4 is selected for use to have than the chlorohydrin rubber of the high Mooney viscosity cladding material as flexible pipe, can guarantee that body is indeformable in the sulfuration course of working.
The utility model is bonded together interior barrier layer 1 and mesoglea 2 by compound expressing technique, like this, can make processing more convenient, reduce cost, and, interior barrier layer 1 and mesoglea 2 to combine fastness higher.
With reference to accompanying drawing 2.The utility model also is provided with Stainless Steel Wire braiding jacket layer 5 outside the glue-line 4 outside on embodiment 1 basis, like this, can further strengthen the crushing resistance and the wear-resisting property of flexible pipe.In Fig. 2, the drawing reference numeral representative identical implication identical with Fig. 1.
Select soft attitude Stainless Steel Wire for use, in the time of can guaranteeing with different Pipe Cutting instrument Pipe Cutting, the utility model section after cut-out does not scatter, and the steel wire head that looses can not appear in the flexible pipe section, more helps the assembling of removable joint.
The utility model can adopt the following steps manufacturing: will as the ternary fluororubber material of interior barrier material with extrude on soft plug barrier layer 1 and mesoglea 2 in forming as the chlorohydrin rubber of mesoglea material is compound; Polyester line or aramid line material are wrapped on the mesoglea by Wiring apparatus, constitute enhancement layer 3; Be coated with bonding rubber cement and oven dry; Adopt T type extruder outside the body that abovementioned steps is finished, to coat outer chlorohydrin rubber; Send sulfurizing pot with steam vulcanization (cure) or by carrying out steam vulcanization (cure) behind the coating plastic skin the more above-mentioned flexible pipe of moulding; Flexible pipe after the sulfuration weaves Stainless Steel Wire braiding jacket layer outward; Slough plug, coil.
Claims (2)
1. low-penetration fuel flexible pipe, the tube wall that it is characterized in that it is made up of interior barrier layer, mesoglea, enhancement layer and outer glue-line, barrier layer, mesoglea, enhancement layer and outer glue-line set gradually from inside to outside in described, and described enhancement layer is constituted by being wrapped in mesoglea outer polyester line or aramid line.
2. a kind of low-penetration fuel flexible pipe as claimed in claim 1 is characterized in that described outer glue-line also is provided with Stainless Steel Wire braiding jacket layer outward.
