Abstract
The utility model relates to a flue gas damper and a sealing device thereof. The sealing device comprises a seal ring; one end of the seal ring is fixed on a frame, and the other end thereof adopts a free end; and an exhaust port and an air inlet, which are formed on the seal ring, extend out of the frame. When the sealing device provided by the utility model is applied in the flue gas damper, and compressed air is pumped in the seal ring, the free end expands to be in tight fit with a rotary vane due to the elastic contact of the seal ring, and the clearance between the rotary vane and the frame is compensated, so that the utility model ensures that the flue gas damper is sealed by 100 percent for a long term; and when the internal pressure of the seal ring is released, the expanded part is shrunk into a groove due to the unique structure of the seal ring, and the clearance between the rotary vane and the frame reappears, so that the flue gas damper can be opened. Therefore, a complete device adopting the flue gas damper has the advantages of safety, reliability, good sealing effect, and convenient maintenance.
