Background
The smoke exhaust fireproof valve is a fire-fighting part, is generally installed on a pipeline of a mechanical smoke exhaust system, is in an open state at ordinary times, has a smoke exhaust function when a fire hazard occurs, is closed when the temperature of smoke in a smoke exhaust pipeline reaches a certain temperature, plays a role in isolating smoke and stopping fire, but the traditional smoke exhaust fireproof valve is poor in controlling the air leakage amount, is poor in sealing property between a closed rear blade and a baffle plate, and is not beneficial to fire extinguishment and flame retardance due to the large smoke leakage amount. According to the existing smoke-discharging fire-resisting valve, a blade is generally composed of a single-layer iron sheet, a blade rotating shaft is welded on the single-layer iron sheet, one end of the blade rotating shaft is connected with an actuating mechanism and is driven to rotate by the actuating mechanism, the other end of the blade rotating shaft penetrates through the shell wall of the smoke-discharging fire-resisting valve and is rotatably connected with the shell wall, and the connecting position is easy to accumulate dust and rust for a long time, so that the rotation is difficult. In the process of inflaming retarding after the smoke exhaust fire damper is closed, the single-layer blade is easily burnt by fire to deform, and the fireproof and heat insulation effects are poor. Therefore, it is necessary to provide a high temperature resistant smoke exhaust fire damper to solve the above problems.
