たことを特徴とする非常閉鎖ダンパー用制御装置。In an emergency closing damper control device in which a temperature fuse is arranged in a damper installed between ducts, a base fixed to the tip of a damper shaft connected to an opening/closing vane and a lock supported pivotally on this base are used. It comprises a plate and a locking lever, a rotatably supported piston that is actuated by gas in the pulling direction, and a striking lever that is actuated by the operation of the temperature fuse, and the base and the locking plate are provided. is elastically biased in one direction, and the locking lever is elastically biased in a direction different from the aforementioned direction, and the rotation of the locking plate is suppressed by the locking of the locking lever, and the piston holds the opening/closing blade in the duct in an open state by being locked in the locking guide groove of the locking plate, and the striking lever strikes the locking lever when the lock is released. The locking lever is released from the locking state of the locking plate, and the base is rotated in the different direction to close the opening/closing blade in the damper. A control device for an emergency closing damper, characterized in that the base is configured to rotate in the different directions to close opening/closing vanes in the damper.
