Abstract
Provided is a blade stabilization apparatus for a relief damper, and more specifically, to a blade stabilization apparatus for a relief damper which can stably maintain an opening angle of a damper blade at any angle when the damper opens or closes after the center of gravity is always aligned with a centerline of a rotating shaft in a perpendicular direction to the damper blade.
Claims3
A blade stabilization apparatus for a relief damper, comprising:
- a rotating shaft installed on a relief damper side;
- a damper blade which is always balanced on the rotating shaft when no pressure is acting thereon while being horizontally positioned on the rotating shaft;
- and
- a counterweight installed perpendicular to a centerline of the rotating shaft,
- wherein a center of gravity of the entire damper blade is necessarily aligned with the centerline of the rotating shaft perpendicular to the damper blade, and
- wherein the damper blade opens or closes by itself while rotating about the rotating shaft according to a pressure difference acting on the damper blade when pressure acts on the damper blade.
