In figure: 1 shell flange, 2 movable fixed blocks, 3 lock rings, 4 safe locking plates, 5 first locking plates, 6 first drive links, 7 type drive links, 8 second drive links, 9 second locking plates, 10 afterburning handles, 11 door shaft structures, 12 door open knob, 13 safety relief bolts, 14 blind plate lids, 15 lip-type packings, 16O RunddichtringO, 17 two auxiliary strippers, 18 right angle escape orifices, 19 springs.
Detailed description of the invention
As shown in Fig. 1 ~ 3, a kind of lock ring type safety quick open blind plate. Lock ring 3 is placed on the conical surface between shell flange 1 and blind plate lid 14, and lock ring 3 is positioned at lock ring upper end while not tightening up, and snaps in the annular groove of shell flange 1, pins blind plate lid 14; When lock ring 3 tightens up, lock ring 3 is outwards deviate from along the conical surface, until depart from the outer of shell flange 1 completely.
Lock ring of the present utility model is fixed and safety relief mechanism, by movable fixed block 2, and safe locking plate 4, auxiliary stripper 17 and safety relief bolt 13 form. Two movable fixed blocks 2 are symmetrically distributed in the both sides of blind plate lid 14, and one end profile of movable fixed block 2 is identical with the interior profile of lock ring 3 of this position, can fit with lock ring 3 well; The other end of movable fixed block 2, with a bit of extension, for the safe locking plate 4 of buckle, is loaded onto after safe locking plate 4, due to the pretightning force effect of the spring of movable fixed block 2 bottoms, can fix firmly lock ring; On safe locking plate 4, with two auxiliary strippers 17, conveniently carry out the dismounting of safe locking plate 4, in the middle of it, have circular hole, coordinate with safety relief bolt 13, in the time that safety relief bolt 13 screws in bolt hole, can not carry out the dismantlement work of safe locking plate 4.
Lock ring retaining mechanism of the present utility model, by the first locking plate 5, the first drive links 6, J type drive link 7, the second drive link 8, the second locking plates 9 form. First locking plate 5 one end and lock ring 3 weld together, and its position is limited by a stop screw and an eccentric plug; First drive link 6 one end are connected with the first locking plate 5, and one end is connected with J type drive link 7; J type drive link 7 other ends are connected with the second drive link 8, and its position is limited by the stopper slot at middle part; On the second drive link 8, be welded with a cylindrical shape interface, join with boosting-rod 10; The other end of the second drive link 8 is connected with the second locking plate 9; One end of the second locking plate 9 is welded on lock ring 3.
When use, safety relief bolt 13 is screwed out to visible right angle escape orifice 18 from bolt hole, release completely when vessel internal pressure power, safety relief bolt 13 is screwed out completely, unload safe locking plate 4, stir movable fixed block 2, away from shell flange 1 outer. Rotate counterclockwise afterburning handle 10, drive link 8 can drive the direction that locking plate 9 tightens up to lock ring to move with locking plate 9 links, drive link 8 can drive J type transmission 7 bars to clockwise rotate with J type drive link 7 links and radially move to lock ring 3 centers of circle simultaneously, and J type drive link 7 can drive locking plates 5 to radially tightening up; Afterburning handle 10 rotates after 180 degree, and the position of drive link 8 is below J type drive link 7, and now lock ring 3 tightens up completely, and due to the self-locking action of this mechanism, lock ring 3 can not be opened automatically. After aforesaid operations completes, the operation that operation door open knob 12 is opened fast opening blind.
The foregoing is only embodiment of the present utility model; not thereby limit scope of patent protection of the present utility model; every equivalent structure or equivalence transformation that utilizes the utility model description and accompanying drawing content thereof to do; or directly or indirectly use other association areas beyond the utility model, all can be considered in scope of patent protection of the present utility model.
