AI Technical Summary
Existing fire-fighting roller shutters have gaps between the shutter and the guide rail, which can cause smoke and dust to leak in.
A steel fire-fighting rolling shutter door was designed, which uses hollow air bladders and an injection mechanism. Fire-fighting water is sent into the hollow air bladders through a reversing valve, causing them to inflate and lock into the sealing groove to enhance the sealing performance. At the same time, a sprinkler system is used to extinguish the fire.
It effectively prevents smoke and dust from leaking through the gap between the roller shutter and the guide rail, improves the sealing performance, and enhances the fire resistance.
