Specific embodiment
As depicted in figs. 1 and 2, a kind of baffle door of the embodiment of the present invention, the baffle door includes：Pitch angle shaped valve buckle 1 and
Twayblade valve plate 2, wherein, through there is axis 3 on twayblade valve plate 2, twayblade valve plate 2 is by 1 turn of axis 3 and pitch angle shaped valve buckle
Dynamic connection, the side Liang Ge edges of twayblade valve plate 2 are connected to elastic packing plate 4, and when twayblade valve plate is closed, elasticity is close
Formed between shrouding 4, twayblade valve plate 2 and pitch angle shaped valve buckle 1 and be provided with and sealing in sealing cavity 5, and twayblade valve plate 2
Multiple passages of the connection of cavity 5, are provided with the air channel connected with passage on axis 3, and in the entrance setting of air channel
There is cutoff device.
As shown in figure 3, being provided with gathering sill 6 on the twayblade valve plate 2, gag lever post 7 is provided with the gathering sill 6,
The elastic packing plate 4 is arranged in the gathering sill 6, is provided with the elastic packing plate 4 and is engaged with the gag lever post 7
Elongated hole, and the gathering sill 6 in be additionally provided with spring 8, one end of the spring 8 compresses with the bottom of the gathering sill 6 and connects
Touch, the other end is compressed with the elastic packing plate 4 and contacted.
Specifically, being additionally provided with the stopping means 9 being engaged with twayblade valve plate 2 in the framework of pitch angle shaped valve buckle 1, set
Uniformly arranged in the passage in twayblade valve plate 2.Axis 3 is located at the line of axis 3 of twayblade valve plate 2.Cutoff device is hand
Dynamic butterfly valve.
When in use, during baffle door opening, the elastic packing plate 4 of the surrounding of twayblade valve plate 2 is in stretched condition.Gear
When plate door is closed, the elastic packing plate 4 of the surrounding of twayblade valve plate 2 is contracted in the gathering sill 6 on valve plate, and elastic packing plate 4
The close contact with the inner surface of pitch angle shaped valve buckle 1 is remained under the resilient force of spring 8.When baffle door is closed, double leaf
The elastic packing plate 4 of the surrounding of piece valve plate 3 constitutes a closed cavity 5 with the inner surface of pitch angle shaped valve buckle 1, in order to further improve baffle plate
The sealing of door, compensation gas are first into inside twayblade valve plate 2 by the air channel inside axis 3, by double leaf plate valve
After the through hole that the multiple of plate 2 is uniformly arranged, uniformly delivered in closed cavity 5.Air pressure in closed cavity 5 is set to be higher than double leaf plate valve
Air pressure in the flue at the outside two ends of plate 2, has thus blocked the circulation of gas in the two ends flue of twayblade valve plate 2, realizes flue
The zero leakage of interior gas.
By foregoing description as can be seen that baffle door provided in an embodiment of the present invention is ensured by using elastic packing technology
Baffle door can realize flexibly switch while having sealing property.With reference to multiple spot compensated with air technology, the zero of baffle door is reached
Leakage and reliable sealing property
