Embodiment Construction

[0027] The present invention will be further described below with specific embodiment, see Figure 1-2 :

[0028] The production process of anti-stop flow high-pressure hose, the specific steps are as follows:

[0029] (1) Mixing: high-speed mixing of raw materials and various additives;

[0030] (2) Cooling: cooling the mixed material after mixing;

[0031] (3) Granulation: carry out twin-screw granulation to the mixed material after cooling;

[0032] (4) Inner tube 10 is extruded: Extrude the inner tube 10 with the extruder extruding the mixed material after granulation, wherein the inner surface of the inner tube 10 is extruded with anti-stop flow protruding strip 60 at one time, and 10 outside the inner tube Adhesive layer 20 is arranged on the surface to form a semi-finished product;

[0033] (5) Closing of semi-finished products: close the market after cooling the semi-finished products;

[0034] (6) Twisted yarn layer is set: inflate the inner tube of the semi-fini...

Abstract

The invention belongs to the technical field of hoses, in particular to a discontinuous flow-preventing high-pressure hose and a production process thereof. The production process comprises the following steps of: (1) mixing; (2) cooling; (3) pelleting; (4) extruding inner tubes; (5) collecting semi-finished products; (6) arranging a twisting layer; (7) performing primary heating treatment; (8) extruding a middle layer; (9) performing secondary heating treatment; (10) extruding outer tubes; and (11) collecting finished products. The raw materials comprise thermoplastic rubber (TPR), thermoplastic elastomer (TPE), thermoplastic polyester elastomer (TPEE) materials, the bonding force of the raw materials is enhanced, the compressive resistance of the hose is improved, discontinuous flow-preventing ribs are longitudinally and integrally molded in the produced hose, unsmooth flow in the hose can be prevented under the condition that the hose is pressed to be flat, and the invention is applied to delivery of compressed air or high pressure liquid and the like.

Description

Technical field: [0001] The invention belongs to the technical field of hoses, in particular to an anti-cutoff high-pressure hose and its production process. Background technique: [0002] Ordinary high-pressure hoses are generally made of plastic or rubber, and are used for conveying pipelines for compressed air or high-pressure liquids. However, the bending radius of this kind of pipe is small, especially when it is bent more than 90 degrees, or it is easy to collapse after being oppressed by external substances, causing the pipeline to transport air or liquid not smoothly, affecting normal work. Invention content: [0003] The purpose of the present invention is to provide an anti-stop high-pressure hose and its production process that can effectively prevent the phenomenon of stoppage of air or liquid during the delivery process after the high-pressure hose is compressed. [0004] The present invention is achieved like this: [0005] The production process of anti-st...
