The model utility content
Problem to be solved in the utility model provides a kind of steel wire wrap style extreme pressure hose assembly, its objective is to realize connecting more closely and more effective sealing in the hydraulic system of ultrahigh pressure.
To achieve these goals, a kind of steel wire wrap style extreme pressure hose assembly provided by the utility model, it connects sealing configuration and comprises the joint core, sleeve and sebific duct, the connection form is sleeve pipe of each suit at the two ends of sebific duct, junction plane is an interference fit, respectively press-fit a joint core from the external port of sleeve pipe, be pressed into length and sleeve pipe is inserted in equal in length, the periphery of joint core adopts the corrugated of annular, and be pawl shape, also interference fit between joint core and the sebific duct, described connection sealing configuration is provided with anti-slip groove muscle structure, promptly establish the muscle of withholding of more piece concave-convex shape ring-type on the inner headed face of sleeve, corresponding with the corrugated convex-concave of the annular of joint core, it is corrugated accordingly that the sebific duct that is clipped in is therebetween formed.
The end form that described anti-slip groove muscle structure is positioned at sebific duct installs protruding left-hand thread inner stopper for corresponding positions on the inner headed face of sleeve, and the joint core is established the left-hand thread outer stopper, makes the outside reflexed of port of sebific duct herein.
The position of described connection sealing configuration outside the port of sebific duct, joint core and sleeve adopt interference fit.
Adopt above-mentioned radial and axial combined labyrinth and carbon gland method, by reasonably withholding distortion, form the close-coupled of mechanical clasps pressure type, the area of contact and the bond strength of sebific duct and jacket casing and joint core have been increased, prevent that effectively unclamping of hydraulic oil sebific duct in the Superhigh Pressure Hydraulic System from coming off and the leakage of hydraulic oil, realize the reliability of sealing, prolonged product working life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a structure cross-sectional schematic of the present utility model;
Fig. 2 is a sebific duct port reflexed structural representation of the present utility model;
Number in the figure is: 1, joint core, 2, sleeve, 3, sebific duct, 4, sealing configuration, 5, anti-slip groove muscle structure, 6, withhold muscle, 7, the left-hand thread inner stopper, 8, the left-hand thread outer stopper.
Embodiment
Shown in Fig. 1 structure cross-sectional schematic of the present utility model, connection sealing configuration 4 of the present utility model comprises joint core 1, sleeve 2 and sebific duct 3, the connection form is sleeve pipe 2 of each suit at the two ends of sebific duct 3, the mating face is an interference fit, respectively press-fit a joint core 1 from the external port of sleeve pipe 2, be pressed into length and sleeve pipe 2 is inserted in equal in length, the periphery of joint core 1 adopts the corrugated of annular, and be back-off shape, also interference fit between joint core 1 and the sebific duct 3, connect sealing configuration 4 and be provided with anti-slip groove muscle structure 5, that promptly establishes more piece concave-convex shape ring-type on the inner headed face of sleeve 2 withholds muscle 6, corresponding with the corrugated convex-concave of the annular of joint core 1, make the sebific duct 3 that is clipped in therebetween form corrugated accordingly.After its physical dimension should guarantee that sebific duct 3 is pressed into, amount of deformation was reasonable, can not cause the steel wire in the sebific duct to fracture.Actual magnitude of interference after withholding is about 0.5mm.During assembling, take the mode of mechanical press mounting, earlier sebific duct 3 is pressed in the sleeve 2, then joint core 1 is pressed in the sebific duct 3.This connecting mode makes sebific duct 3 by reasonably withholding distortion, has increased the area of contact of sebific duct 3 with jacket casing 2 and joint core 1, forms the close-coupled of mechanical clasps pressure type, has improved the reliability that connects and seal.The joint core 1 at this assembly two ends connects with the operation element of hydraulic system, control unit etc. respectively.
