Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Base
In embodiments of the invention, those of ordinary skill in the art obtained on the premise of creative work is not made it is all its
Its embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1, present embodiments provide it is a kind of force Double-sealing plate sluice valve, as shown in figure 1, it include valve body 1,
Valve seat 2, valve rod 6, bonnet 7, support 8, handwheel 9, valve packing room 10, wherein, valve seat is divided into two, and vertically spaced sets
In in the cavity of valve body, flashboard is arranged between two valve seats, and one end of valve rod is connected with flashboard, and the other end of valve rod passes through valve
Filler chamber and support are connected with handwheel, wherein, the flashboard includes main gate-board 5 and auxiliary gate-board 3, the main gate-board 5 and auxiliary gate-board 3
It is connected by spring carrier arm 4, the two ends of spring carrier arm 4 are fixed on the outer surface of main gate-board 5, the middle part of spring carrier arm 4
