Abstract
PURPOSE: To combine the smoke exhausting function and the fireproofing function and to ensure the operation of the smoke exhausting device at the fire occurrence by locating at an intermediate position of a smoke exhaust duct the smoke exhausting device in which a partition such As a damper vane is operated by a multistaged cylinder.
CONSTITUTION: When the fire occurs, a smoke signal turns over an electromanetic switching valve 50 to a position R or a manual switching valve 51 is turned over manually to a position F, so as to open the damper vanes 5, 5'. In more detail, the compressed air within the first cylinder chamber 37 is discharged, thereby releasing the pushing of the first piston 34 in the forward direction. Accordingly, the first piston rod is moved rearewardly by the force of a spring 36 to open the damper vanes 5, 5'. Thus the smoke exhausting function is performed. When the temperature in the smoke exhaust duct 1 rises up, and the fuse of a heat sensitive switching valve 60 is melted to move the valve 60 to a position D, the damper vanes 5, 5' are closed again. In other words, the air within the second cylinder chamber 27 is exhausted to release the pushing of the second piston 34 in the rearward direction. Therefore, the piston rod is advanced by the force of a spring 26, thereby closing the damper vanes 5, 5'. Thus, the fireproofing function is perfomed.
