摘要
PURPOSE: A damper apparatus for overpressure exhaust of an air pressurization and smoke control system is provided to prevent toxic gas and smoke from flowing into a refuge route by maintaining proper differential pressure of a smoke control area as an elastic member controls restitution within a specified range.;CONSTITUTION: A damper apparatus for overpressure exhaust of an air pressurization and smoke control system comprises a damper blade(30), and an elastic member(40). The damper blade is installed at the both sides of a case(20). The damper blade rotates according to air pressure around a shaft(21). The elastic member restores the circulated damper blade. A bent part(32) is formed by bending a part of the front end of the damper blade. A weighted member(31) maintains the balance of the torque due to the weight of the damper blade.;COPYRIGHT KIPO 2010
