Embodiment 4
As shown in Figure 3, Figure 4, inner core cover 10 and the contractive pressure overcoat 11 of hose coupling are installed, by the extruding of crimping equipment to the contractive pressure overcoat 11 of outside, extruding are formed to the wire rope that front end is stripped out, inner core cover 10 and flexible pipe inner glue layer sheet 1 close contact of joint, connect as one.
Hose coupling inner core cover and contractive pressure overcoat are assembled, inside hose is inserted under the effect of external force, by the contraction deformation of equipment to contractive pressure overcoat, compressive force is formed to the pressure-bearing skeletal structure that flexible pipe mesoglea and wire rope are formed, the distortion of contractive pressure overcoat forms evenly spaced ridge convex 13 to the pressure-bearing skeletal structure that flexible pipe mesoglea and wire rope are formed, prevent joint pull-off, inner core cover is processed with seam 14, the seam 14 of inner core cover forms gapless with the convex 13 pairs of wire rope pressure-bearing skeletons of the ridge of contractive pressure overcoat and is engaged mutually; And inner glue layer sheet 1 is under the punching press of external force, the seamless close contact of inner core cover 10 with joint, forms some sealed rubber rings.
Testing property
Subjects: embodiment 1, embodiment 2, embodiment 3, control group rush stake flexible pipe.
Control group rushes stake flexible pipe and chooses ordinary steel rope as reinforced layer, inside and outside bonding inner glue layer and outer glue-line respectively.
Index test is as following table:
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all mode of executions.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
