SEAL STRIP STRUCTURE FOR DAMPER

摘要

The present invention relates to a seal strip structure of a damper used for a fluid transfer duct. The first feature of the present invention is a damper (M) installed in a duct (D) transferring the fluid to adjust the flow rate of the fluid or block the fluid flow. The damper (M) is formed by installing a frame body (1) formed on the outer part; blades (3) formed in a multi-staged type in the frame body (1) and rotatably opened or closed as rotary shafts (2, 2a) are axially installed on both sides; and a seal strip (6) made of elastomer to be sealed by being overlapped between front ends of the blade (3). The second feature of the present invention is a damper (M) formed by fixing and installing a frame body (1) formed on the outer part; a blade (30) opened or closed while being vertically lifted by a cylinder device (50) in the frame body (1); and a hoof seal (60) made of elastomer having a sealing force between front ends of the frame body (1) and the blade (30). The present invention has an effect of completely blocking the flow of fluid such as waste heat gas in power plants or harmful gas for human bodies with excellent sealing force by forming a seal strip having excellent elasticity and resiliency from elastomer in the blade of the opened or closed damper.
