Description
Technical field
The present invention relates to the hermatic door technology, relate in particular to a kind of novel seal door that is applicable to the synchronous locking of linkage type of nuclear power plant.
Background technology
Nuclear power plant's hermatic door is the access that personnel pass in and out purifier, and its requirement of strength can remain intact sealing under SSE level seismic (seismal, and operating pressure is a negative pressure, belongs to the equipment that the radiation environment uses.In order to reach operator safety and to the protection of environment, nuclear power plant's hermatic door is wanted to satisfy the requirement that the radioresistance environment uses, and existing nuclear power plant hermatic door is still waiting to promote in radioresistance and the whole evenly ability of sealing.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provide a kind of structure assembling flexibly, balanced, the linkage type that can resist nuclear radiation and carry positive and negative pressure of the whole pressurized of the encapsulant novel seal door of locking synchronously on the dependable performance, sealing facade.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of linkage type is the novel seal door of locking synchronously, comprises door leaf, doorframe, driving mechanism, interlinked mechanism and insertion retaining mechanism; Said driving mechanism comprises driving gear and the driven gear that is meshed; Said interlinked mechanism comprises A connecting rod and jointed connecting rod, and wherein jointed connecting rod comprises two above B connecting rods and axial adjustment parts, fixes through the axial adjustment element coaxial between the B connecting rod; Said insertion retaining mechanism comprises suitable bearing pin, locking pin and inclined-plane voussoir, and locking pin is provided with pin-and-hole, and bearing pin inserts in the pin-and-hole, and it is corresponding one by one with the B connecting rod to insert retaining mechanism; The central axis of said driving gear and driven gear is all fixed perpendicular to door leaf; Driven gear and A rod hinge connection are in the A pin joint; A connecting rod and jointed connecting rod are articulated in the B pin joint; B connecting rod and corresponding with it locking pin are articulated in the C pin joint, and bearing pin is fixed on the door leaf, and the inclined-plane voussoir is fixed on the doorframe; When hermatic door was closed locking, all locking pins all inserted in the corresponding inclined-plane voussoir, and door leaf tightly is pressed on the edge, guarantee the sealing of door leaf and doorframe.In order to prevent the nuclear radiation leakage, be provided with the weather strip of anti-the nuclear radiation by common practice at the edge of door leaf.
Above-mentioned hermatic door closes door leaf on doorframe earlier in use, lets the sealing lip of the weather strip of anti-the nuclear radiation be close to plane, doorframe outer; Rotate driving gear; The drive driven gear rotates, because the articulated structure of driven gear, A connecting rod, jointed connecting rod and locking pin is that rotating shaft is rotated synchronously thereby the pulling jointed connecting rod makes a plurality of locking pins with corresponding bearing pin; The edge of locking pin slides on the inclined-plane of inclined-plane voussoir, in locking pin inserts the inclined-plane voussoir, reaches locking state; The weather strip of door leaf edge plays airtight effect.The plane crush of general design inclined-plane voussoir is 2 ~ 3mm, suitably adjusts the axial adjustment parts and regulates the decrement that the angle of B connecting rod and locking pin can change weather strip, reaches the desired seal effect.In this structure, can design a plurality of insertion retaining mechanisms as required, through adjustment axial adjustment parts, make through rotating driving gear, can lock so that a plurality of locking pin inserts in the adaptive inclined-plane voussoir opposite house synchronously; Adjustment on the doorframe adaptive a plurality of inclined-planes voussoir with the bonding surface of locking pin on want coplane, inclined-plane voussoir coplanar error is about 0.3mm.
Preferably, the number of said interlinked mechanism is two covers, is separately fixed at the left and right sides of door leaf; Can certainly concrete flexible design become three covers, quadruplet or more cover interlinked mechanisms according to the shape of door leaf, on the simultaneous interlinked mechanism, the number of the B connecting rod of design can be the same or different, and designs the same number of B connecting rod usually.For the hermatic door of symmetrical number interlinked mechanism, the line at the center of the A pin joint that designs preferably is positioned at two end points of diameter through the axle center of driven gear, makes the overall structure of hermatic door more symmetrical, and assembling or use are all more convenient.
Preferably, the number of said insertion retaining mechanism is four, six, eight or ten, promptly constitutes the synchrolock locking structure.
Preferably; The front that door leaf extends to door leaf is passed in the rotating shaft of said driving gear; And fix with operating grip, general design operation handle is two-way long operating grip, the operator is no matter inboard or all can open the door or close door operation according to the direction indication that provides at outer side of door at door; Preferably, said door leaf is provided with the indicating dial of indicating operating grip direction of rotation and rotational lock to put in place; Can know whether door leaf locks, lock information such as whether putting, how to remove locking in place through indicating dial.
Preferably, said driven gear is a sector gear, because the rotational angle of locking pin itself is less, thereby there is no need to design the circular driven gear that whole circumference all has toothing, reduces the space hold of driving mechanism and wastes with avoiding making.The preferred toothed arch section of driven gear is the arc of 60～135 ° of central angles, and adopts height or angle correcting, can reach the requirement that hermatic door is locked fully and opened fully fully.
Generally in the both sides of doorframe an edge is arranged, wherein one side Men Yuan is welded on the purifier, and another side is installed hinge seat, so that door leaf is installed, the inclined-plane voussoir that matches with locking pin is fixed on the inboard of an edge; Rely on the support door leaf of hinge can freely open, close; Door leaf is provided with lead glass window, can observe the inner situation of purifier through the lead glass on the hagioscope.
Beneficial effect: linkage type provided by the invention is the novel seal door of locking synchronously; When hermatic door is closed; Through rotating driving gear; Can control retaining mechanism and door leaf is carried out multiple spot insert locking synchronously and connect, make anti-nuclear radiation encapsulant balanced consistent, reach hermatic door reliable sealing effect under nuclear radiation environment at the crush of whole facade; Make the nuclear power station purifier reach the instructions for use of no nuclear leakage under the antidetonation condition simultaneously.
