Most of the multi-leaf air outlets are installed on the stairs or aisles of the building, and they are usually closed. Once a fire accident occurs, the DC24V AC data signal is used to control the open air outlet for a long distance, and the relative centrifugal fan in the system software will be The coordination work will immediately transport the flue gas in the exhaust duct.

Before installing the multi-leaf air outlet, the physical properties of the air outlet must be carefully considered. The drainage piece used is an adjustable or dismountable product. It is fast and reliable in regular adjustment and disassembly, and there is no looseness after precise positioning. Multi-leaf air outlet manufacturers apply to the ventilation and air-conditioning engineering system software with fire safety regulations, usually open and close, when a fire occurs, the fusible ring in the temperature circuit breaker will melt at 70 degrees, and the gate valve will be closed to exhaust the smoke system. The exhaust fire damper circuit breaker.

Multi-leaf air outlet is installed in the aisle or smoke-proof pretreatment room, and the air outlet of the smoke exhaust system of the windowless house can be lifted from the ceiling or installed in the armpit corner. The multi-leaf air outlet must pay attention to the key points of the installation during the construction of the project. Only by ensuring proper installation can its characteristics be fully revealed.
The purpose of the multi-leaf air outlet is to expel the smoke immediately according to the ventilation duct when a fire occurs, and transport it into fresh air, so as to ensure that the staff and rescue workers inhale the right air when carrying out fire rescue and disaster relief. Physical damage: Toxic gases, dense smoke, and air pollutants floating in the air, to ensure that the source of fresh air enters to ensure that everyone who is trapped can breathe normally.

The structure of the multi-leaf air outlet is relatively simple, and its function is stable. It is a positive displacement fan. Now it has gradually been widely used. The air volume is proportional to the number of revolutions. Compared with the general air supply outlet, the gas pulsation is small, the vibration is also small, and the noise is low. The impeller on the root shaft of the multi-leaf air outlet and the inner hole surface of the oval casing, the front and rear covers of the multi-leaf air outlet, and the fan impellers always maintain a slight space. The air inlet is conveyed to the discharge side along the inner wall of the shell.
