Embodiment
Embodiment, see shown in Fig. 1 to Fig. 3, the linkage structure of hydraulic pipe line comprises Female connector fittings 1, inner core 2, flexible pipe 3, inner sleeve 4, overcoat 5 and transit joint 6.Transit joint 6 be closely tied in inner core 2 head and by the dismountable locking of Female connector fittings 1.The middle part of inner core 2 is equipped with tightening nut 21.Flexible pipe 3 is set on inner core 2, and inner sleeve 4 is withheld to be had on the inner core 2 of flexible pipe 3 in cover, and front end is threaded with inner core 2, and abuts tightening nut 21.Overcoat 5 is placed in inner sleeve 4 and also wraps up inner sleeve 4 completely, and front end abuts tightening nut 21.What tightening nut 21 defined inner sleeve 4 and overcoat 5 withholds position, prevents it from relative displacement occurring.The outer wall of inner core 2 is provided with multiple annular groove 22 vertically continuously, the inwall of inner sleeve 4 is provided with vertically continuously multiple annular and presses tooth 41, groove 22 and pressure tooth 41 one_to_one corresponding, flexible pipe 3 is closely fixed in the gap of groove 22 and the formation of pressure tooth 41.Inner sleeve 4 is withheld on inner core 2, is limited between the two by flexible pipe 3.The internal diameter of overcoat 5 is less than the external diameter of inner sleeve 4, the outer end of inner sleeve 4 is placed under the effect of pressure facility, due to the interference fit of overcoat 5 and inner sleeve 4, inner sleeve 4 is subject to the squeezing action of overcoat 5 and reduces diameter, the pressure tooth 41 of inwall is pressed into flexible pipe 3, make flexible pipe 3 deformation and the space of fully laminating groove 22 and the formation of pressure tooth 41, the non-flat form by groove 22 and pressure tooth 41 can prevent it in being axially moved.The amount of withholding of flexible pipe is the magnitude of interference of outer casing internal diameter and inner sleeve external diameter.
See the sectional view of Fig. 4 inner core 2, inner core 2 front end has tapered portion 23 and an extendable platform 24.The external diameter of tapered portion 23 reduces before backward, is wherein provided with an annular groove 231.Extendable platform 24 is extended forward by tapered portion 23.The internal diameter that the inwall of tapered portion 23 and extendable platform 24 has the first flow guide structure 25, first flow guide structure 25 reduces gradually by after forward direction.The internal diameter that the rear end inwall of inner core 2 has the second flow guide structure 26, second flow guide structure 26 expands gradually by after forward direction.
See Fig. 3 and Fig. 4, transit joint 6 rear end inwall has the attachment face matched with extendable platform 24 and tapered portion 23, during installation, extendable platform 24 and tapered portion 23 at least partially with transit joint 6 inside attachment face closely cooperate, and further sealed by the seal ring 61 be positioned in annular groove 231, Female connector fittings 1 is locked in outside joint.Front end and the transit joint internal diameter of the first flow guide structure 25 match, and the internal diameter of rear end and inner core 2 matches.The front end of the second flow guide structure 26 and the internal diameter of inner core 2 match, and rear end and flexible pipe 3 internal diameter match.The internal diameter that first flow guide structure 25 and the second flow guide structure 26 are changes gradually, and such as can form the chamfering structure of taper, can also be convex structure in addition, or the combination of taper and arc-shaped.
Designed by tapered portion front end extendable platform, the assemblage gap between inner core and transit joint can be reduced, both are made to have the abutted surface of a level, can realize coordinating more closely, anti-fluid by inclined-plane interstitial diffusion out, thus have and better connect effect and sealing effect, the less loss of energy.The process of flow guide structure is carried out in internal diameter change place of pipeline, especially the transition that flow guide structure realizes connecting pipeline internal diameter is set in the internal diameter joint of inner core and transit joint, inner core and flexible pipe, bootable fluid is at a comparatively level and smooth spatial flow, fluid is avoided to produce turbulent flow through reducing cross section, reduce the energy consumption of hydraulic system, reduce the jerk of hydraulic system, reduce the heating value of fluid.
Above-described embodiment is only used for further illustrating the modified node method of a kind of hydraulic pipe line of the present utility model; but the utility model is not limited to embodiment; every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all fall in the protection domain of technical solutions of the utility model.
