Laminated hose
To provide a laminated hose capable of achieving both pressure-resistant performance and oscillating durability performance. The laminated hose ( 1 ) comprises a plurality of reinforcing layers ( 12 ) laminated to the hose body ( 11 ), and each of the plurality of reinforcing layers ( 12 ) includes a reinforcing wire ( 13 ). A wire density (ρ) of the reinforcing layer ( 12 ) in all of the plurality of reinforcing layers ( 12 ) is 90% or more and less than 96%.
1 . A laminated hose comprising a hose body and a plurality of reinforcing layers laminated on the outer circumferential side of the hose body, and each of the plurality of reinforcing layers includes a reinforcing wire, wherein
a wire density of the reinforcing layer in all of the plurality of reinforcing layers is 90% or more and less than 96%, and
a wire bending density of the reinforcing layer in each of the plurality of reinforcing layers does not exceed 100% when the laminated hose is bent at a bending radius determined by the specifications of the laminated hose, the wire bending density being the wire density of the reinforcing layer when the laminated hose is bent and viewed from an inner circumference in a radial direction of bending to an outer circumference and the bending radius being a radius of curvature generated at the innermost circumference of the laminated hose in the radial direction of bending when the laminated hose is bent.
2 . The laminated hose according to claim 1 , wherein the wire density of the reinforcing layer in each of the plurality of reinforcing layers decreases from the innermost reinforcing layer closest to the hose body to the outermost reinforcing layer farthest from the hose body.
3 . The laminated hose according to claim 2 , wherein a winding angle of the reinforcing wire in each of the plurality of reinforcing layers is 40° or more and 70° or less.
4 . The laminated hose according to claim 2 , wherein the laminated hose is a wire spiral hose including the reinforcing wire wound in a spiral shape.
5 . The laminated hose according to claim 1 , wherein a winding angle of the reinforcing wire in each of the plurality of reinforcing layers is 40° or more and 70° or less.
6 . The laminated hose according to claim 5 , wherein the laminated hose is a wire spiral hose including the reinforcing wire wound in a spiral shape.
7 . The laminated hose according to claim 1 , wherein the laminated hose is a wire spiral hose including the reinforcing wire wound in a spiral shape.
8 . A laminated hose comprising a hose body and a plurality of reinforcing layers laminated on the outer circumferential side of the hose body, and each of the plurality of reinforcing layers includes a reinforcing wire, wherein
a wire density of the reinforcing layer in all of the plurality of reinforcing layers is 90% or more and less than 95%, and
a wire bending density of the reinforcing layer in each of the plurality of reinforcing layers does not exceed 100% when the laminated hose is bent at a bending radius determined by the specifications of the laminated hose, the wire bending density being the wire density of the reinforcing layer when the laminated hose is bent and viewed from an inner circumference in a radial direction of bending to an outer circumference and the bending radius being a radius of curvature generated at the innermost circumference of the laminated hose in the radial direction of bending when the laminated hose is bent.
9 . The laminated hose according to claim 8 , wherein the wire density of the reinforcing layer in each of the plurality of reinforcing layers decreases from the innermost reinforcing layer closest to the hose body to the outermost reinforcing layer farthest from the hose body.
10 . The laminated hose according to claim 9 , wherein a winding angle of the reinforcing wire in each of the plurality of reinforcing layers is 40° or more and 70° or less.
11 . The laminated hose according to claim 9 , wherein the laminated hose is a wire spiral hose including the reinforcing wire wound in a spiral shape.
12 . The laminated hose according to claim 8 , wherein a winding angle of the reinforcing wire in each of the plurality of reinforcing layers is 40° or more and 70° or less.
13 . The laminated hose according to claim 8 , wherein the laminated hose is a wire spiral hose including the reinforcing wire wound in a spiral shape.
