NON-DIRECTIONAL SMOKE CONTROL DAMPER HAVING CHAIN GEAR TYPE BLADE ADVANCING/RETREATING DEVICE |
摘要 |
A non-directional smoke control damper includes a central blade (11), a plurality of outer blades (12) and a blade advancing/retreating device; an outer edge of the central blade (11) overlaps with an opening edge of the plurality of outer blades (12); a support shaft (110) is disposed to pass through the overlapping portion of the edges; a rear end of the support shaft (110) is coupled through a shaft coupling plate (230); and if the central blade (11) advances forwards, the plurality of outer blades (12) advance forwards in order so that a gap is formed at each edge between the central blade (11) and an adjacent outer blade and between a prior-order outer blade and a posterior outer blade to form a blowing passage, thereby allowing an air current to flow into the vestibule through the blowing passage. |
