Description
Technical field
The present invention relates to hermatic door technology, particularly relate to a kind of Novel sealing door being applicable to the linkage type synchronous locking 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 negative pressure, belongs to the equipment that radiation environment uses.In order to reach operator safety and the protection to environment, nuclear power plant's hermatic door wants the requirement that can meet the use of radioresistance environment, and existing nuclear power plant hermatic door need to promote in the ability of radioresistance and overall consistent seal.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides the assembling of a kind of structure flexibly, on dependable performance, sealing facade the overall pressurized of encapsulant balanced, can the Novel sealing door of linkage type synchronous locking of Antiradiation and carrying positive and negative pressure.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A Novel sealing door for linkage type synchronous locking, comprises door leaf, doorframe, driving mechanism, interlinked mechanism and insertion retaining mechanism; Described driving mechanism comprises the driving gear and driven gear that are meshed; Described interlinked mechanism comprises A connecting rod and jointed connecting rod, and wherein jointed connecting rod comprises two or more B connecting rod and axial adjustment parts, is fixed between B connecting rod by axial adjustment element coaxial; Described insertion retaining mechanism comprises suitable bearing pin, locking pin and slope wedge block, and locking pin is provided with pin-and-hole, and bearing pin inserts in pin-and-hole, and inserts retaining mechanism and B connecting rod one_to_one corresponding; The central axis of described driving gear and driven gear is all fixed perpendicular to door leaf, driven gear and A rod hinge connection are in A pin joint, A connecting rod and jointed connecting rod are articulated with B pin joint, B connecting rod and locking pin corresponding are with it articulated with C pin joint, bearing pin is fixed on door leaf, and slope wedge block is fixed on doorframe; When hermatic door closes locking, all locking pins all insert in corresponding slope wedge block, door leaf is tightly pressed on an edge, guarantees the sealing of door leaf and doorframe.In order to prevent nuclear radiation from revealing, at the edge of door leaf, common practice is provided with the weather strip of resistance to nuclear radiation.
Above-mentioned hermatic door in use, first door leaf is closed on doorframe, the sealing lip of the weather strip of resistance to nuclear radiation is allowed to be close to doorframe outer plane, rotate driving gear, drive driven gear rotates, and due to the articulated structure of driven gear, A connecting rod, jointed connecting rod and locking pin, thus pulls jointed connecting rod to make multiple locking pin with corresponding bearing pin for rotating shaft synchronous rotary, the edge of locking pin slides on the inclined-plane of slope wedge block, until locking pin inserts in slope wedge block reach locking state; The weather strip of door leaf edge plays airtight effect.The plane crush of general design slope wedge block is 2 ~ 3mm, and suitably adjustment axial adjustment parts regulate the angle of B connecting rod and locking pin can change the decrement of weather strip, reach required sealing effectiveness.In the structure shown here, multiple insertion retaining mechanism can being designed as required, by adjustment axial adjustment parts, making by rotating driving gear, multiple locking pin can be made synchronously to insert opposite house in adaptive slope wedge block and lock; Multiple slope wedge block adaptive on adjustment doorframe with the bonding surface of locking pin on coplanar, slope wedge block coplanar error is about 0.3mm.
Preferably, the number of described interlinked mechanism is two covers, is separately fixed at the left and right sides of door leaf; Can certainly become three covers, four covers or more cover interlinked mechanism according to the concrete flexible design of the shape of door leaf, on simultaneous interlinked mechanism, the number of the B connecting rod of design can be the same or different, usually the same number of B connecting rod of design.For the hermatic door of symmetrical number interlinked mechanism, the line at the center of designed A pin joint, through the axle center of driven gear, is preferably positioned at two end points of diameter, makes the overall structure of hermatic door more symmetrical, assembles or uses all more convenient.
Preferably, the number of described insertion retaining mechanism is four, six, eight or ten, namely forms synchrolock locking structure.
Preferably, the rotating shaft of described driving gear extends to the front of door leaf through door leaf, and fix with operating grip, general design operation handle is two-way long operating grip, and no matter operator all can carry out opening the door or door-closing operation according to the direction indication provided inside door or at outer side of door; Preferably, described door leaf is provided with the indicating dial indicating operating grip direction of rotation and rotational lock to put in place; Can know whether door leaf carries out locking by indicating dial, lock and whether put in place, how to remove the information such as locking.
Preferably, described driven gear is sector gear, because the rotational angle of locking pin itself is less, thus there is no need to design the circular driven gear that whole circumference all has toothing, reduces the space hold of driving mechanism and avoids manufacturing waste.The toothed arch section of preferred 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 completely and opened completely completely.
Generally have an edge in the both sides of doorframe, wherein one side Men Yuan is welded on purifier, and another side installs hinge seat, to install door leaf, the slope wedge block matched with locking pin is fixed on the inner side of an edge; Rely on the support door leaf of hinge freely can open, close; Door leaf is provided with lead glass window, the situation of purifier inside can be observed by the lead glass on hagioscope.
Beneficial effect: the Novel sealing door of linkage type synchronous locking provided by the invention, when hermatic door is closed, by rotating driving gear, retaining mechanism can be controlled Multipoint synchronous insertion locking connection is carried out to door leaf, make anti-nuclear radiation encapsulant balanced consistent at the crush of overall facade, reach hermatic door reliable sealing effectiveness under nuclear radiation environment; Make nuclear power station purifier reach instructions for use without nuclear leakage under earthquake-resistant condition simultaneously.
