[0002] Fire dampers are a key device used in building fire protection systems. Their main function is to prevent the spread of fire. When the smoke temperature reaches 280°C, people have basically evacuated and smoke exhaust is meaningless. However, the smoke is already filled with fire, so the valve automatically closes to block the smoke and prevent the fire from spreading.

[0003] Most of the existing fire dampers are composed of a front baffle, a rear baffle and a valve body, wherein the front baffle, the rear baffle and the valve body are mostly assembled by welding or bolting. This connection method requires external tools for disassembly and assembly. The disassembly of the fire damper is troublesome and time-consuming, which is not conducive to subsequent maintenance. In addition, the high-temperature smoke generated when a fire occurs and the spreading fire often cause damage to the fire damper, thereby affecting the normal use of the fire damper to block smoke.

[0004] To this end, we proposed a fire damper that can block the spread of smoke. Utility Model Content
