The smoke barrier door adopts a single axis electric double-layer louver double barrier structure. The smoke baffle door has 100% tightness (with air seal) at the design pressure and design temperature. The operation of all baffles is flexible, reliable, and easy to maintain. The smoke baffle door has electric actuators for remote control and on-site manual operation, and also provides on-site installed baffle position indicators.
The complete set of smoke baffle includes frame, blades, actuator, handwheel, and sealed air butterfly valve. Simultaneously, it is required that all necessary isolation barriers be operated flexibly, reliably, and conveniently. The smoke baffle can operate under the maximum pressure difference, close tightly without bending or jamming, and the baffle should match the limit device in the fully open and fully closed positions. The working gear of the bearing or baffle is equipped with oil lubrication, and a clear and visible mark indicating the position of the baffle plate is installed at the end of the shaft, and an interlocking limit switch is equipped. There are hanging ears or holes at appropriate positions outside the framework for easy transportation and installation.
Each baffle component has sufficient strength to withstand the entire high temperature range of smoke<200 ℃ without damage, adhesion, deformation or leakage. Each baffle component is designed based on the maximum possible design pressure value. Each baffle and driving device is designed to withstand corrosion from surrounding media under all operating conditions. The bypass baffle door can open (close) quickly, with a guaranteed action time of ≤ 25 seconds. The internal sealing gasket of the baffle can be disassembled or replaced. And its external components can be disassembled or replaced while the baffle is in operation. The connection method between the baffle door and the flue is welding.
