Abstract

The utility model discloses a superhigh pressure flexible pipe, comprising a sealing joint, a sleeve cylinder, and a pipe body, the pipe body from the internal to the external, respectively comprises a polyurethane pipe layer (1), a first synthetic rubber pipe layer (3), a second synthetic rubber pipe layer (5), a polyurethane pipe layer (7), and a rubber pipe layer (9), metal wires (2, 4, 6, 8) are disposed among pipe layers, and are winded on the external wall of an inner layer pipe in a spiral shape, and an outer layer pipe covers the inner layer pipe. The superhigh pressure flexible pipe is advantaged by no deformation under the condition of high pressure, no sweat, no seepage, corrosion resistance, aging resistance, and long service lifetime.

Description

A kind of extreme pressure hose

Technical field

The utility model relates to a kind of tubular article, especially a kind of extreme pressure hose.

Background technique

Along with social progress and industrial and agricultural production fast development, more and more higher for delivery of the flexible pipe demand of pressurized air, highly pressurised liquid and powdered materials, the flexible pipe that generally uses both at home and abroad at present mainly contains rubber pipe and metal tube.Rubber hose is flexible, and bending radius is less, but bending angle is when spending greater than 90, the flexible pipe in bending part is easily flat to be fallen, hinder the circulate of transported substance, rubber pipe is yielding simultaneously, and is easily aging, working life is shorter, its inwall of metallic hose mostly is corrugated, and permissible velocity is low, and resistance is large, bending radius is large, easily is corroded and frangibility.Simultaneously above-mentioned two kinds of pipes exist all that to bear pressure lower, and the defective of easily breaking and being out of shape is difficult to satisfy high pressure, ultrahigh pressure operation needs.

The model utility content

The purpose of this utility model is to overcome the prior art deficiency, and a kind of extreme pressure hose assembly is provided.The purpose of this utility model realizes by following technical proposals.The utility model comprises SEALING FITTING, sleeve and body, body is respectively polyurethane pipe layer from inside to outside, the first synthetic sebific duct layer, the second synthetic sebific duct layer, polyurethane pipe layer and rubber pipe layer, be equipped with wire between each pipe layer, wire is spirally wrapped around on interior one deck pipe outer wall, and outer one deck pipe covers and is rolled on interior one deck pipe.

The utility model is that multi-layer flexible pipe covers to wrap up in and forms, and has been provided with between each layer flexible pipe and adds powerful wire, thereby compared with prior art has the following advantages:

(1) can bear higher interior pressure and external pressure, body can bear interior pressure and reach as high as 150mPa, and nothing distortion under condition of high voltage, without sweating ne-leakage.

(2) the utility model adopts various different materials flexible pipes to cover to wrap up in to form, and it has good corrosion resistance, and ageing resistance and sealing are high, long service life.

The utility model can be widely used in hydraulic power and transmit or high-pressure delivery water, gas, oil and powdered materials.

From above-mentioned situation as can be known the purpose of this utility model can realize.

Fig. 1 is the utility model pipe structure diagram.

Embodiment

As shown in Figure 1, pipe-making method is made polyurethane pipe layer 1 at first routinely, then on polyurethane pipe layer outer wall, twine in the shape of a spiral first layer metal silk 2, outside it, cover and wrap up in the first synthetic sebific duct layer 3, the described first synthetic sebific duct layer 3 is the synthetic sebific duct layer of polyurethane and butadiene acrylonitrile rubber, after outside it, twining in the shape of a spiral second layer metal silk 4, cover again and wrap up in the second synthetic sebific duct layer 5, after synthetic glue-line outer wall twines three-layer metal silk 6 in the shape of a spiral, cover again and wrap up in polyurethane pipe layer 7, after twining in the shape of a spiral the 4th layer of wire 8 on the polyurethane pipe layer outer wall, cover again and wrap up in rubber pipe layer 9.The radical of the used Stainless Steel Wire of helical winding wire is decided as required, and present embodiment is all selected 4, by sleeve sealing head is connected with body at last to get final product.

Claims

1. extreme pressure hose, comprise SEALING FITTING, sleeve and body, it is characterized in that: body is respectively polyurethane pipe layer (1), the first synthetic sebific duct layer (3), the second synthetic sebific duct layer (5), polyurethane pipe layer (7) and rubber pipe layer (9) from inside to outside, be equipped with wire (2,4,6,8) between each pipe layer, wire is spirally wrapped around on interior one deck pipe outer wall, and outer one deck pipe covers and is rolled on interior one deck pipe.
