(4) inner tube is extruded: the batch mixing after the granulation is extruded inner tube with extruder, and wherein the disposable Preventing No-flow from Appearing raised line of having extruded of the internal surface of inner tube arranges bonding layer at inner tube outer surface, forms semi-finished product;
(5) half storey product closing quotation: with closing quotation after the semi-finished product cooling;
(6) arrange and to add the twisted filament layer: inflation and outside described inner tube, twine the twisting silk and form and add the twisted filament layer in the cooled half-finished inner tube of step (5);
(7) heat treated first: step (6) is wound with the inner tube that adds twisted filament carries out heat treated;
(8) extrude in the mesosphere: the twisted filament external application extruder that adds after step (7) heat treated is squeezed into the mesosphere, and at the outer surface in mesosphere bonding layer is set;
(9) heat treated again: the product that step (8) is obtained carries out heat treated;
(10) outer tube is extruded: the outer surface in the mesosphere after step (9) heat treated is squeezed into outer tube with extruder and is formed finished product;
(11) finished product closing quotation.
The above-mentioned twisted filament that adds is that the excellent reinforcing fiber of high strength and industrial filament are twisted the twisted filament that adds that forms.
Cutoff-preventing high-pressure hose, outside inner tube, be arranged with successively mesosphere and outer tube, between inner tube and mesosphere, mesosphere and outer tube, be provided with bonding layer, also be provided with between the bonding layer in inner tube and mesosphere and mesosphere and add the twisted filament layer, vertically one-body molded on the internal surface of inner tube have a Preventing No-flow from Appearing raised line.
The cross section of above-mentioned Preventing No-flow from Appearing raised line is circular oval square or trapezoidal.
The advantage that the present invention gives prominence to compared to existing technology is:
1, is furnished with TPR (thermoplastic elastomer), TPE (thermoplastic elastomer (TPE)), TPEE (thermoplastic polyester elastomer) material in the raw material of the present invention, strengthened the Adhesion force of raw material, improved the compressive resistance of flexible pipe;
2, vertical one-body molded Preventing No-flow from Appearing raised line that has can prevent flexible pipe in situation about being flattened in the flexible pipe that the present invention produces, and circulation has some setbacks in the pipe;
3, this reality invention between inner tube and mesosphere, be provided with adopt that the excellent reinforcing fiber of high strength and industrial filament twisting forms add twisted filament layer, intensity height;
4, the present invention is applicable to the conveying of pressurized air or highly pressurised liquid etc.
