Embodiment
explain further details below in conjunction with the structure and the use principle of the high-pressure rubber pipe assembly that accompanying drawing provides the utility model.
are illustrated in figure 1 as the structural representation that the first kind of pipe joint that utilizes the utility model to provide reaches the high-pressure rubber pipe assembly that constitutes with linking together of heavy caliber high-pressure rubber pipe.Its pipe connector structure comprises that the middle part is provided with 12 the core pipe 2 that is preferably bulge loop (also can be the projection ring that projection at interval constitutes) 1 and inserts the heavy caliber high-pressure rubber pipe; The two ends of outer wall are provided with outside thread 3, inwall is the overcoat 5 of slope 4 shapes, and the week circle that snaps in overcoat one end blocks lobe 6 and front end nut of being inserted in the overcoat two ends 7 and back end nut 8.Being the boundary with bulge loop or projection ring 1 wherein is divided into the core pipe connecting end 9 that is used for being connected with other pipe fittings and can inserts the pipe linkage section 10 of sebific duct end; Pipe linkage section 10 outer walls of above-mentioned bulge loop or projection ring 1 right flank and this core pipe are set to the slope shape structure; This core pipe pipe linkage section 10 that is the slope shape structure inserts removes sebific duct 12 1 ends that outer glue-line 11 backs are made up of inner glue layer and steel wire casing ply 18; And be that the overcoat 5 of slope 4 shapes is inserted in inwall; The week circle card lobe 6 that is made up of five lobes (three lobes, pintongs or six lobes) as shown in Figure 5 is snapped in overcoat 5 sebific duct side ends, and the front and back ends nut 7,8 of annulus 13 is screwed in the two ends of overcoat in being provided with.
are in the structure of the pipe assembly of above-mentioned high-pressure rubber hose coupling and sebific duct formation; Back end nut 8 is screwed in the overcoat 5; Annulus 13 will advance all circle card lobes 6 to insert along the slope of overcoat 5 inner side surfaces in it, make the sebific duct that is inserted in the core pipe 10 be extruded distortion; Front end nut 7 and the overcoat left end of annulus 13 are when being threaded in being provided with simultaneously; Not only make and be inserted in sebific duct in the core pipe 10 by jam-packed; The follow-up of back end nut simultaneously further advances week circle card lobe 6 to insert along the slope of overcoat 5 inner side surfaces, sebific duct in the centre is out of shape strengthens the function that resistance to plucking takes off and seals.
are illustrated in figure 2 as the structural representation of second kind of heavy caliber high-pressure rubber pipe assembly.Promptly constitute on the outer wall of above-mentioned first kind of heavy caliber high-pressure rubber pipe assembly core pipe pipe linkage section 10 slope shape three (can set one or more as required) step annular groove or concavo-convex annular grooves 14 are set; The internal face of its external sleeve is provided with three (can set one or more as required) corresponding step annular groove or convex-concave annular groove 15 simultaneously; Make the sebific duct that is compressed in core tube wall step annular groove or the concavo-convex annular groove 14 be curved shape; Improve the join strength of sebific duct and pipe joint assembly greatly, strengthened the function that resistance to plucking takes off and seals greatly.
In the structure of the heavy caliber high-pressure rubber pipe assembly of above-mentioned Fig. 1 and Fig. 2:
---as shown in Figure 6; In order to improve the join strength of extremely thick high-pressure rubber pipe of tube wall and pipe joint; Removed outer glue-line 11 backs and protruded in the bulge loop 1 at high-pressure rubber pipe pipe joint middle part by inner glue layer and steel wire casing ply 18, and in steel wire casing ply 18 week circle wedge some chocks 19.By the front end nut 7 of annulus 13 in being provided with overcoat 5 is screwed again.
---the internal diameter of core pipe 2 is identical with the internal diameter of the sebific duct that is connected 12; The heavy caliber high-pressure rubber pipe assembly of this structure can solve effectively in the existing technology that to compare the sebific duct internal diameter that is connected little owing to constitute pipe joint core pipe diameter, and causes the liquid in pipe flow velocity to stop up the problem that causes flow to diminish at the pipe joint place;
---in the structure of above-mentioned heavy caliber high-pressure rubber pipe assembly; Formation core pipe 2 slope shape structure outer wall sides can also be the pawl shape along the step annular groove or the concavo-convex annular groove 14 of circumference; Make to be compressed on that the sebific duct tube wall is runcinate extruding bending in core tube wall side step annular groove or the concavo-convex annular groove 14, can avoid sebific duct from its pipe joint, to extract fully;
---what circumference was provided with at least two (preferably three) as shown in Figure 3 on the outer wall of front and back ends nut 7,8 holds pawl 16; Be that available hand is screwed in the front and back ends nut with the overcoat that constitutes the high-pressure rubber hose coupling assembly, need not to use special tool can realize the assembled on site of high-pressure pipe connector assembly.Can certainly be on the outer wall of front and back ends nut 7,8 circumference be provided with the pawl nest 17 of at least two (preferably three) as shown in Figure 4, can use simple tools to realize the assembled on site of high-pressure pipe connector assembly.
The method step that utilizes high-pressure rubber hose coupling assembly that the utility model provides and sebific duct to constitute the pipe joint assembly is:
(1) at first will constitute the overcoat of heavy caliber high-pressure rubber pipe assembly and the compacting connecting end that the rear end nut is inserted in large-bore hose;
(2) sebific duct is suppressed the outer glue-line of connecting end and peel off the length that is equivalent to core pipe slope shape outer wall (or overcoat), steel is compiled the winding framework layer and is exposed;
(3) insert the end of core pipe slope shape in the sebific duct pipe end, make its end withstand on the outer side surface of side or annular convex ring of annular convex ring the some chocks of week circle wedging in steel wire casing ply;
(4) with described overcoat one end be pushed into the removal that is inserted in core pipe slope shape the steel of outer glue-line compile and twine on the framework layer;
(5) will snap in overcoat 5 sebific duct side ends by the week circle card lobe 6 that three lobes, pintongs or five lobes constitute, simultaneously back end nut and overcoat will be screwed into through screw thread; Simultaneously front end nut is inserted in the core pipe by the left side of core pipe, overcoat one end is inserted wherein, can realize the assembling of high-pressure rubber hose coupling assembly and sebific duct then through the front end and back end nut of screwing.
