Both sides side wall.
When anti-fire smoke expelling valve is closed, valve blade 2 is rotated, and the state of mutual overlap joint is transformed into from open mode.Due to
The section of metallic elastic piece 10 be in circular arc, therefore valve blade 2 rotate close during between metallic elastic piece 10 between
Untill compression laminating completely is become progressively smaller until, so that be in interference fit between valve blade 2 and metallic elastic piece 10, from
And the sealing of anti-fire smoke expelling valve is improve, and can effectively stop the intensity of a fire or smog, eliminate potential safety hazard.When valve blade 2
When slave phase mutually overlaps state and goes to open mode again, because metallic elastic piece 10 is flexible, therefore metallic elastic piece 10 is extensive again
Circular arc is arrived again, so as to metallic elastic piece 10 can still match somebody with somebody with valve blade 2 in interference when ensure that the closing of valve blade 2 next time
Close.
Depression 10.2 is provided with along the length direction of metallic elastic piece 10 on the arc surface of metallic elastic piece 10, depression 10.2 is located at
On the center line of metallic elastic piece 10, valve blade 2 is embedded in depression 10.2.Completely closed when valve blade 2 is turned to, i.e. valve
When being in overlap joint state between gate flap piece 2, valve blade 2 is just embedded in groove 12, so that the state of valve blade 2 is more
Stabilization, makes the valve blade 2 to carry stronger impulsive force, prevents from opening valve blade 2 because the intensity of a fire is excessive.
Because the more small liquid of corrosivity may be carried in smog, in order that anti-fire smoke expelling valve has more preferable anti-corruption
Erosion and rust quality, valve blade 2 and framework 1 are equipped with zinc coat.That is valve blade 2 and framework 1 is by galvanizing technique.
The operation principle of the anti-fire smoke expelling valve is as follows：
When need to be discharged fume, drive component 3.4 drives wherein one rotating shaft 3.1 to rotate counterclockwise, the rotating shaft 3.1 drive with
The rocking bar 3.2 that it is fixedly connected is rotated, and rocking bar 3.2 is rotated and drives gangbar 3.3 to be moved along the axis direction of vertical valve blade 2
It is dynamic, so as to drive other rocking bars 3.2 to rotate, and then drive all rotating shafts 3.1 to rotate, realize synchronous turn of all valve blades 2
It is dynamic, open valve blade 2.
When need to be prevented fires, drive component 3.4 drives wherein one positive hour hand of rotating shaft 3.1 to rotate, the rotating shaft 3.1 drive with
The rocking bar 3.2 that it is fixedly connected is rotated, and rocking bar 3.2 is rotated and drives gangbar 3.3 to be moved along the axis direction of vertical valve blade 2
It is dynamic, so as to drive other rocking bars 3.2 to rotate, and then drive all rotating shafts 3.1 to rotate, even if the synchronous axial system of all valve blades 2.
After rotation is finished, in mutually overlap joint between valve blade 2, near valve blade 2 and the phase lap of bonding jumper 9 of the both sides of framework 1
Connect.Sealing strip 7 produces deformation under the active force of the clinch 6 of valve blade 2, and self adaptation is made up between the clinch 6 of valve blade 2
Joint gap so that anti-fire smoke expelling valve has better seal.
Simultaneously in valve blade 2 when mutually overlap joint state is turned to from open mode, valve blade 2 and metallic elastic piece
Spacing between 10 is become progressively smaller until untill compressing laminating completely, so that being between valve blade 2 and metallic elastic piece 10
Interference fit, so as to improve the sealing of anti-fire smoke expelling valve.
Completely closed when valve blade 2 is turned to, i.e., when being in overlap joint state between valve blade 2, valve blade 2 is just embedding
If entering in groove 12, groove 12 has a spacing power to valve blade 2, valve blade 2 is kept the state of mutual overlap joint.Simultaneously
Spring 5 also has a thrust to valve blade 2, valve blade 2 is kept the state of mutual overlap joint.Acted on simultaneously in the two power
Under, the valve blade 2 is carried stronger impulsive force, prevent from opening valve blade 2 because the intensity of a fire is excessive.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
