AIR FLOW CONTROLLER AND FIRE DAMPER IN AN AIR FLOW DUCT |
摘要 |
A fire damper in an air duct (2) is formed by a flap (12) which in its closed position bears on a flange (6) which extends inward from the duct wall, to form a seal. The flap (12) is biased to the closed position and held open by a cable (24) which is gripped by a releasable mechanism, such as a ball clutch. The release is triggered by a fusible cartridge (34) which extends into the duct (2). |
