Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the mode of execution of the utility model is not limited thereto.
Embodiment 1
Like Fig. 1, shown in 2, the utility model mainly comprises inner sleeve spare, and said inner sleeve spare inside has through hole, and this inner sleeve spare is processed by metallic material.Said inner sleeve spare comprises inner core 2, and these inner core 2 integral body are truncated conical shape, on this inner core 2, are provided with sawtooth 4, and said sawtooth 4 is looped around on the outer surface of inner core 2, and is positioned at the upper end of inner core 2.Simultaneously, also be provided with boss 3 in the lower end of said inner core 2, this boss 3 be connected on the bottom surface of inner core 2 and with this inner core 2 structure that is solidified as a whole, and the outside diameter of this boss 3 is greater than the outside diameter of inner core 2, promptly this boss 3 protrudes in inner core 2, and is as shown in Figure 2.
On said inner sleeve spare, also be provided with overcoat pipe fitting 1; Said overcoat pipe fitting 1 is also processed by metallic material; And this overcoat pipe fitting 1 has the through hole that matches with boss 3 for inside; Said overcoat pipe fitting 1 with the inwall of its through hole is connected on the outer surface of boss 3 after boss 3 cooperates, to form with boss 3 between overcoat pipe fitting 1 and the inner core 2 be the semiclosed cavity of bottom surface thereby make.For the medium that prevents to circulate in the inner sleeve spare leaks through the gap between inner sleeve spare and the overcoat pipe fitting 1; At the seal ring 6 that also is provided with on the said boss 3 between boss 3 and overcoat pipe fitting 1; Said seal ring 6 is an O type circle, and is made by plastic material.For the ease of seal ring 6 is connected on the boss 3, on said boss 3, also be provided with the groove 5 that is complementary with seal ring, said seal ring 6 be socketed on the groove 5 after groove 5 cooperates.
For the ease of two overcoat pipe fittings 1 are interconnected, on said overcoat pipe fitting 1, also be provided with draw-in groove 7.
Embodiment 2
As shown in Figure 3, present embodiment is compared with embodiment 1, and its overall structure is identical, and unique difference only is that its external sleeve pipe fitting 1 is provided with flange plate 8 and draw-in groove 7 is not set, and this flange plate 8 and overcoat pipe fitting 1 structure that is solidified as a whole.
Embodiment 3
Shown in Fig. 1~6; The PE composite pipe of present embodiment comprises composite pipe main body 9; Comprise internal layer and the skin of processing by polythene material in this composite pipe main body 9, also comprise the mesosphere that is arranged between internal layer and the skin, and this mesosphere is the framework layer of being processed by steel wire.Be provided with link at these composite pipe main body 9 one ends; Described in said link overall structure such as the embodiment 1; And the semiclosed cavity that forms between inner sleeve spare and the overcoat pipe fitting 1 matches with composite pipe main body 9; Be that inner core 2 is provided with sawtooth 4 one ends and stretches into composite pipe main body 9 inside, the outer surface of inner core 2 is connected with the inwall of composite pipe main body 9.Boss 3 then is positioned at the outside of composite pipe main body 9, and the end face that the end face of composite pipe main body 9 is connected boss 3 is on the bottom surface of semiclosed cavity.Simultaneously, the inwall of said overcoat pipe fitting 1 then is connected on the outer surface of composite pipe main body 9, thereby is connected after making composite pipe main body 9 and semiclosed cavity cooperating on the link that overcoat pipe fitting 1 and inner sleeve spare form.
