Specific embodiment
As depicted in figs. 1 and 2, the utility model discloses a kind of nuclear power plant's fire resisting damper, including a valve buckle for rectangle
1, some valve blocks 2 are rotatably connected in the valve buckle 1, the valve block 2 is connected by a connecting rod 3 with executing agency 4,
By remote control executing agency, the rotation of valve block 2 can be controlled, so as to realize the opening and closing of fire resisting damper, such as Fig. 3-Fig. 5
Shown, the valve block 2 includes the fox shape piece 12 that a rotating shaft 11 and two longitudinal edges are interlocked, the rotating shaft 11 and fox shape piece
Linked together in the middle of 12 longitudinal direction, connected mode is usually riveting；Innovative point of the present utility model essentially consists in the rotating shaft
11 active section section is square, and several are passed through partly in the middle of relative two sides of the rotating shaft 11 and the longitudinal direction of fox shape piece 12
Hollow conical head rivet is mutually fixed, because foursquare each side is relatively wide, with the contact area of fox shape piece 12 than larger so that
Rotating shaft 11 and the connection of fox shape piece 12 are more firm, while rotating shaft 11 can provide bigger torsion to fox shape piece 12 when rotating；It is described
The occlusal side inner side of two fox shape pieces 12 has an anticreep groove 13 for indent so that occlusal side is difficult to disengage when being heated；
As shown in figure 8, two terminations of the valve block 2 are respectively provided with a headkerchief 7, the headkerchief include headkerchief body 21,
Tongue 22 and linkage handle 23 with the one of headkerchief body 21, the connection tongue are connected with several of the rectangular side of headkerchief body 21
First 22 stretch into two inner sides of fox shape piece 12, and are mutually riveted with fox shape piece 12, and the linkage handle 23 is connected with connecting rod 3 respectively.
On the one hand, by adding headkerchief 7, make the integral rigidity and intensity of valve block 2 better, on the other hand, the linkage handle 23 of one makes
The processing for obtaining valve block 2 is more convenient, also more firm.
As shown in fig. 6, another innovative point of nuclear power plant's fire resisting damper described in the utility model is the valve buckle 1
Inner side is provided with elastic sealing strip 5, the elastic sealing strip 5 be placed in two short sides of valve block 2 where the inner side of valve buckle 1, the phase
A metallic elastic piece 6 is provided with adjacent two scrap (bridge)s of valve block 2.When fire resisting damper inoperative, valve block 2 is full-gear, elasticity
Diaphragm seal 5 is in free state, and when fire resisting damper works, valve block 2 is closed mode, and now elastic sealing strip 5 is pressed by valve block 2
Tightly, deform and move inward slightly, it is ensured that valve block 2 is in close contact with elastic sealing strip 5, meanwhile, it is adjacent when valve block 2 is closed
Metallic elastic piece 6 at two scrap (bridge)s of valve block 2 is squeezed and is driven plain so that the gap location between adjacent two valve blocks 2
In minimum, sealing problem when fire resisting damper works is solved.
As shown in fig. 7, another innovative point of nuclear power plant's fire resisting damper described in the utility model is it also includes one
Individual self-locking device 8, the self-locking device 8 include one be fixed on the main shaft of executing agency 4 determine from locking plate 14 and spring
Position pin 15, it is described to be provided with a location hole matched with spring holder 15 from locking plate 14.When fire resisting damper is closed, self-locking
Piece 14 is aligned with main axis to closed position, the now location hole from locking plate 14 with the lock bolt of spring holder 15, heads into
Location hole, pinning is rotated from locking plate 14, it is ensured that valve block 2 no longer resets after fire resisting damper is closed.
