Embodiment
As shown in Fig. 1 ~ Fig. 6, be that a kind of structure provided by the invention is simple, fitting operation easily, be suitable for the composite flange structure used in small space.Described composite flange structure comprises connecting bolt 1, main flange plate 2 and secondary flange plate 3, described main flange plate 2 is connected as a whole with described secondary flange plate 3 by described connecting bolt 1, described connecting bolt 1 is made up of the single head stud containing polished rod section 4, described main flange plate 2 is provided with the tapped hole 5 suitable with the connecting thread of described single head stud, described secondary flange 3 is provided with single head stud through hole 6, described main flange plate 2 and described secondary flange plate 3 pass hole 6 by described single head stud and described tapped hole 5 is as a whole with being connected of described single head stud.By connecting bolt 1 being revised as the single head stud containing polished rod section 4, and then original unthreaded hole on main flange plate 2 is revised as the tapped hole 5 suitable with the connecting thread of described single head stud, like this, when by the composite flange anatomical connectivity pipeline described in the application or seal container, just can easily make described main flange plate 2 and described secondary flange plate 3 by described single head stud through hole 6 and described tapped hole 5 as a whole with being connected of described single head stud, namely the tapped hole 5 described in being screwed in by connecting thread after passing hole 6 by single head stud through described single head stud when connecting tube or seal container is to realize the connection of described main flange plate 2 and described secondary flange plate 3.Like this, by just no longer needing independent nut when described composite flange anatomical connectivity pipeline or seal container, thus make the overall structure of composite flange structure described in the application become simpler, attended operation becomes convenient, is particularly useful for the operation carrying out pipeline connection and seal of vessel in small space.
Above-mentioned mode of execution, in order to the composite flange structure described in the application is when connecting tube in small space or seal container, especially when repair demolition, described single head stud can not drop easily in unloading process, cause the impact on miscellaneous equipment, lead at described single head stud and perforation 6 is also provided with one section of Drop-proof screw thread 7 suitable with the screw thread of described single head stud, described Drop-proof screw thread 7 is positioned at described secondary flange plate 3 side adjacent with joint outer part, described single head stud passes hole 6 through described single head stud after being threaded through described Drop-proof screw thread 7 by the connecting thread of its head.Like this, in unloading process, even if after the threaded end of single head stud exits tapped hole 5, still can not drop from secondary flange plate 3.
We know, no matter are the connection of pipeline or the sealing of container, all need to arrange seal ring 9 between main flange plate 2 and secondary flange plate 3, to seal the assemblage gap between main flange plate 2 and secondary flange plate 3.But when carrying out the installation of seal ring 9 in small space, very inconvenient, be easy to equally in installation process drop.For solving the problems of the technologies described above, described in the application, composite flange structure also comprises seal ring mounting assembly 8, described seal ring mounting assembly 8 vertically reciprocally movement be arranged between described main flange plate 2 and described secondary flange plate 3, be arranged between described main flange plate 2 and described secondary flange plate 3 by described seal ring mounting assembly 8 is dismountable for the seal ring 9 sealing the assemblage gap between described main flange plate 2 and described secondary flange plate 3.Now, the preferred structure of described seal ring mounting assembly 8 is the structure being arranged to described seal ring mounting assembly 8 comprise transition ring 10 and prepackage stud 11, and main flange plate 2 is improved with secondary flange plate 3 simultaneously, namely seal ring is set on the end face of described main flange plate 2 groove 12 is installed, the end face of described secondary flange plate 3 is provided with seal ring and compresses protruding 13, and be provided with on an end face of described transition ring 10 and compress protruding 13 suitable seal ring mounting grooves 14 with described seal ring, on another end face of described transition ring 10, setting and described seal ring are installed the suitable seal ring of groove 12 and are compressed bulge loop 15, then when mounted, first described transition ring 10 is pre-installed on described secondary flange plate 3 by described prepackage stud 11.Like this, seal ring 9 dropping in an installation is just effectively avoided.
In above-mentioned mode of execution, described seal ring mounting assembly 8 is mounted in main flange plate 2 and secondary flange plate 3, for this reason, conveniently described seal ring mounting assembly 8 is installed between main flange plate 2 and secondary flange plate 3, following two kinds of structures can be adopted, namely in described transition ring 10, connecting bolt is first provided with through hole 16, described transition ring 10 is arranged on described main flange plate 2 and described secondary flange plate 3 by described connecting bolt through hole 16, and described transition ring 10 is reciprocally moved vertically by described connecting bolt 1; Another kind of structure in described transition ring 10, also arranges the connecting bolt radially extended pass groove 17, described transition ring 10 is arranged on described main flange plate 2 and described secondary flange plate 3 by described connecting bolt through groove 17 is dismountable, and described transition ring 10 is reciprocally moved vertically by described connecting bolt 1.
