Abstract
The utility model provides a high-pressure liquid conveying pipe, belongs to the technical field of pipelines, and solves the problems that an existing high-pressure pipe is poor in tolerance and is heavy. The high-pressure liquid conveying pipe comprises an inner pipe and an outer pipe, wherein the outer pipe is sleeved on the inner pipe, a weaving layer is arranged between the inner pipe and the outer pipe, the weaving layer is tightly wound on the outer wall of the inner pipe, the inner wall of the outer pipe is adhered to the weaving layer, the weaving layer is provided with multiple meshes, the inner wall of the outer pipe is provided with bulges which correspond to the meshes one to one, the corresponding meshes are filled with the bulges, and the bulges and the outer pipe are in an integrated structure. According to the high-pressure liquid conveying pipe provided by the utility model, the integral strength of the high-pressure pipe can be increased by the weaving layer, the friction at the outer part of the high-pressure liquid conveying pipe can be simultaneously increased, the inner part of the high-pressure liquid conveying pipe is provided with a rifling type pressurizing groove, the liquid pressure can be increased, and the high-pressure liquid conveying pipe is more suitable for hydraulic transmission.
Description
Technical field
The utility model belongs to pipe technology field, particularly a kind of high-pressure transfusion tube.
Background technology
In cleaning equipment field, that pressure hose can not adapt to the demand of present high-pressure work far away in the past, the increase of pressure, must propose higher requirement to the technical index of high-pressure pipe, for meet requirements, after this have the thickening of employing rubber layer or plastic layer, also have in rubber layer or plastic layer winding steel wire in addition outward, to strengthen the compressive resistance of high-pressure pipe, but this high-pressure pipe seems very heavy, and its bending reelability is poor.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing high-pressure pipe, and it is stronger to have proposed a kind of body intensity, and can increase to hold by position and rub, and more can save the high-pressure transfusion tube of material.
The purpose of this utility model can realize by following technical proposal: a kind of high-pressure transfusion tube, it is characterized in that, it comprises inner and outer tubes, outer tube sleeve on inner pipe, is provided with braid between described inner and outer tubes, and described braid is closely wrapped on outer wall of inner tube, inwall and the braid of outer tube are bonding, braid has multiple mesh, and the inwall of described outer tube is provided with and above-mentioned mesh projection one to one, projection be filled in corresponding mesh and with outer tube be integral type structure.
In above-mentioned a kind of high-pressure transfusion tube, described braid is formed along the braiding of inner tube direction screw winding with X-shaped interleaved mode by least two braided wires.
In above-mentioned a kind of high-pressure transfusion tube, described braided wire is dacron thread.
In above-mentioned a kind of high-pressure transfusion tube, described braided wire is steel wire.
In above-mentioned a kind of high-pressure transfusion tube, described inner and outer tubes all adopt PVC injection mo(u)lding.After inner tube injection mo(u)lding, take advantage of it completely braid not to be wound around up when cooling, braided wire can be blocked and be absorbed in inner tube outer surface, to increase both degree of being connected firmly, again by outer tube taking above-mentioned half-blank as mould injection mo(u)lding, outer tube wall is infiltrated through and in the mesh of braid, forms projection.
In above-mentioned a kind of high-pressure transfusion tube, the outside face of described outer tube circumferentially arranges many convex edges along body direction, and each convex edge is spaced and forms by multiple projections, and described projection and outer tube are integral type structure.Projection can synchronously form with the injection moulding of outer tube, forms interval and be convenient to body bending between projection.
In above-mentioned a kind of high-pressure transfusion tube, the inwall of described inner tube is provided with rifling shape supercharging groove.Make liquid screw in compression, can increase liquid pressure.
Compared with prior art, the braid of this utility model can increase the bulk strength of high-pressure pipe, and outside can increase friction simultaneously, and inside has rifling shape supercharging groove can increase liquid pressure, is more suitable for hydraulic pressure transmission.
