Role: In the event of a fire actuator pressure delivery outlet, its internal electric actuator will open air, warm sense smoke or manual fire alarm will be turned on, a positive pressure fan tower roof opens automatically on pressurized air shaft Multi-page pressurized air outlet, front room by the stairs will be a steady stream of pressurized air outlet on the front air chamber, the front room to maintain a positive pressure to ensure that smoke does not spread in the region, while giving escape space. When the temperature is higher than 280 ° C were no longer escape the possibility of its internal fuse will blow, air automatically shut down to prevent the fire from spreading. Application: National high-rise building fire smoke positive outlet design specification of national standards, these parts should set up a separate mechanical exhaust system 1, does not have the natural conditions of the stairwell smoke, fire elevator room or shared room. 2, the use of natural smoke stairwell, it does not have the front room of natural smoke. 3, closed refuge floors. Positive outlet for leafy exhaust port, we must note that the terms of the installation or from the choice, we must pay attention to some of its specifications set the parameters, because it is to decide whether the multi-leaf more efficient exhaust port can play a key factor in their performance, let's take a detailed look: Under normal circumstances, we learned that the normally closed leafy exhaust port with a remote device, depending on whether the perimeter by selecting multi-leaf smoke hole in the head, according to B chicane duct calculation, calculated according to the duct extension meters, no separate sets of items; in addition we have learned is that the choice of leafy exhaust port for the primary control parameter specifications. We note that the choice of more and exhaust port when its features, such as automatic open and close, open and close the manual, manual reset, signal output, remote control and other requirements. Finally, we have learned is that especially leafy exhaust port construction, installation point is that we must check before installing air operating mechanism is intact, the action is flexible and effective. For more information about this knowledge we will continue to bring you organize.
