FIG. 1 is a schematic cross-sectional view of an embodiment of the present invention.
FIG. 2 is a sectional view of two hose assemblies in a connected state.
The specific implementation mode is as follows:
specific embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are provided to facilitate understanding of the technical spirit of the present invention and should not be construed as limiting the scope of the claims of the present invention.
Referring to fig. 1 to 2, the embodiment of the present invention is as follows: the hose comprises a hose 1, and is characterized in that at least one structural layer of the hose 1 with a multilayer structure is clamped by the clamping surfaces of an outer flange sheet 2 and an inner flange sheet 3 of a clamp type flange, the wall surface of the hose 1 consists of an inner glue layer 4, an inner glue cloth layer 5, a support reinforcing layer 6 with wound steel wires and an outer protective layer 7 from inside to outside, and the hose 1 and the clamp type flange are integrally vulcanized and fixed; in practical use, when the hose 1 is stretched by external force, the structural layer clamped by the clamping flange increases the tensile resistance of the hose 1, or two friction surfaces are arranged between the structural layer of the hose 1 and the inner and outer flange sheets (3 and 2) of the clamping flange, and when the clamping flange is screwed through the bolts passing through the through holes on the clamping flange, the friction force generated by the friction surfaces is quite large, so that the hose 1 is prevented from being separated from the clamping flange.
In order to further improve the tensile resistance of the hose assembly of the present invention, the outer flange 2 and the inner flange 3 have concave-convex clamping surfaces with mutually matched shapes, and the structure layer of the clamped hose 1 also forms a concave-convex body, which increases the area of the clamping surface, i.e. increases the friction force, and simultaneously, the displacement stroke and the deformation resistance of the displacement of the clamped structure layer after being stretched by an external force are increased, which is summarized as the connection strength between the hose 1 and the clip type flange is increased.
More specifically, the clamping surfaces of the inner flange sheet (3) and the outer flange sheet (2) are in a mutually matched wave shape, the wave crest of the outer flange sheet (2) is opposite to the wave trough of the inner flange sheet (3), and the wave crest and the wave trough are curved surfaces, so that when the clamping surfaces and the structural layer of the hose (1) are increased, the clamping surfaces cannot generate shearing acting force on the structural layer of the hose (1), no shearing damage is generated on the structural layer, and the improvement of the connection strength and the guarantee of the service life are facilitated.
The multilayer structure of the wall surface of the hose 1 has been described, and the outer flange sheet 2 and the inner flange sheet 3 clamp the inner rubberized fabric layer 5 or/and the clamping support layer 6 of the hose 1; because the inner rubberized fabric layer 5 is formed by the glue layer and the synthetic fiber cloth, and is formed by at least one glue layer and at least one synthetic fiber cloth, the inner rubberized fabric layer has high tensile strength, after being fastened and clamped by the inner flange sheet (3) and the outer flange sheet (2), the friction force between the inner rubberized fabric layer 5 and the inner flange sheet (3) and the outer flange sheet (2) is quite large, and the resistance for preventing the inner rubberized fabric layer 5 from being separated from the clamp-type flange is greatly improved; the clamping surface of the clamping type flange or the supporting layer 6 of the clamping type hose 1, the supporting layer 6 is formed by a glue layer and at least one layer of winding steel wire, wherein the layer of the winding steel wire is selected according to the technical requirements of the hose 1, for example, two layers or three layers of winding steel wire are provided, because the winding steel wire has extremely high tensile resistance, the winding steel wire is clamped by the clamping type flange, when the hose 1 is stretched by external force, the clamping type flange is extremely difficult to separate, or the winding steel wire can deform the winding steel wire only by extremely high tensile force in the clamping state, so that the tensile resistance of the hose assembly is improved; on the other hand, the clamping flange or the inner rubberized fabric layer 5 and the supporting layer 6 of the hose 1 are clamped at the same time, so that the tensile resistance of the hose assembly is further improved.
The corner 8 formed by the clamping surface of the inner flange piece 3 and the inner ring wall surface of the clip-on flange is a smooth curved surface (shown in fig. 1), because the inner rubberized fabric layer 5 or/and the supporting layer 6 clamped by the clip-on flange covers the inner ring wall surface of the inner flange piece 3 and extends to form the main body of the hose 1 after coming out of the clamping surface, that is, when the hose 1 is acted by external force, the corner 8 forms a main resistance point to the hose 1, if the corner 8 is a vertical angle, inevitable shearing force is generated to the inner rubberized fabric layer 5 or/and the supporting layer 6 of the hose 1, so that the inner rubberized fabric layer 5 or/and the supporting layer 6 are damaged, and the hose 1 is broken at the position of the corner 8, therefore, the corner 8 is designed into a smooth curved surface, which increases the processing cost, but avoids the damage, improves the service life and avoids the high pressure, Severe accidents occur in a high tensile force state.
In order to further improve the tensile resistance of the hose assembly, at least one fixing ring 9 is fixedly arranged at the corner formed by the other surface of the clamping surface of the inner flange piece 3 and the inner ring wall surface, when the clip-on flange clamps the inner rubberized fabric layer 5 of the hose 1, the end part of the winding steel wire in the supporting layer 6 is fixedly connected with the fixing ring 9, so that the supporting layer 6 with the strongest tensile force of the hose 1 plays a main role in resisting external force tension, and the improvement of the connection strength of the hose 1 and the clip-on flange is beneficial.
The round outer surfaces of the inner flange sheets (3) and the outer flange sheets (2) are provided with a lantern ring (10) pressed at the outer end of the clamping surface, and the lantern ring (10) plays a role in protecting the inner rubberized fabric layer (5) or/and the supporting layer (6) between the inner flange sheets (3) and the outer flange sheets (2), such as sealing protection; or the end portions of the inner rubberized fabric layers 5 have extensions (not shown) towards the circular outer surfaces of the inner and outer flange pieces (3, 2) against which the collar 10 is pressed, the collar 10 being preferably made of a high-strength metal material, such as a steel band, so that there is a friction surface between the collar 10 and the extensions against displacement of the inner rubberized fabric layers 5, which further improves the strength of the connection of the hose 1 to the clip flange.
In practical use, a plurality of hose assemblies are connected to form a hose with a proper length, the clamp flange is connected with the clamp flange of another hose assembly through a bolt (shown in figure 2), the bolt not only realizes the connection of the hose assemblies, but also can increase the friction force between the clamp flange and the clamped inner rubberized fabric layer 5 or/and the support layer 6, the connection of the clamp flanges has a contact surface between the two clamp flanges, in order to improve the sealing performance of the contact surface, the inner rubberized layer 4 extends to cover the outer end surface of the outer flange sheet 2 to form a sealing surface 11, and the arrangement structure of the sealing surface 11 not only realizes sealing, but also avoids the defects that the conventional end outer surface is provided with a sealing ring, and the processing preparation is easy to damage or fall off.
In order to improve the protection of the hose 1, the outer protective layer 7 of the hose 1 comprises an outer fabric layer and an outer glue layer connected to the support layer 6, so as to improve the overall properties of the hose 1, such as wear resistance, corrosion resistance or fire resistance.
