[0002] Fire dampers are generally installed at the places where air ducts pass through fire walls and structural deformation joints to control fires. Their function is that when the smoke temperature reaches the predetermined temperature, people have basically been evacuated and smoke exhaust is no longer of practical significance. At this time, the smoke is already carrying fire, and the valve automatically closes to prevent the fire from spreading. The fire damper blades are an important component of the fire damper. In order to enable the blades to rotate inside the fire damper, a rotating shaft needs to be welded to the blades.

As the blade continues to be squeezed, the degree of bulging of the second airbag increases. At this time, the bulged second airbag pushes the top plate to move upward, so that the top plate acts on the bottom of the blade and the rotating shaft, so as to support the bottom of the rotating shaft and the blade, prevent the misalignment between the blade and the rotating shaft, and cause the welding of the blade and the rotating shaft to deviate, thereby affecting the processing of the protective valve.
