[0002] Fire dampers are used to prevent flames and smoke from spreading to other areas through the exhaust system during a fire, thus playing a role of fire isolation. These fire dampers are usually installed on exhaust ducts, such as air conditioning exhaust ducts. When closed, they do not affect the normal exhaust function. However, when a fire occurs, they will automatically open to prevent flames and smoke from spreading through the exhaust system.
[0003] For example, the invention with application number CN202110050489.3 relates to a smoke exhaust fire damper, including a valve body and a fire blade assembly arranged in the valve body, and also including two sealing seats arranged on the inner wall of the valve body in a relative manner, wherein the fire blade assembly is arranged between the two sealing seats, and a sealing groove is provided on the sealing seat, and a telescopic seal for inserting into the sealing groove is provided on the side of the fire blade assembly close to the sealing seat; the invention improves the contact mode between the traditional blade and the valve body when the blade is in a closed state, converts the hard contact closure into a soft contact closure, and the roller rolls on the arc-shaped side of the sealing seat and cooperates with the expansion and contraction of the first spring, which can reduce the damage to the fire blade itself during the closing process and improve the service life of the fire blade, and the soft contact closure is used in conjunction with the sealing seat and the sealing member, and in the process of closing the fire blade, the sealing effect of the valve body closing is achieved, and the fire prevention effect of the fire blade against high-temperature smoke is improved.
