For leafy exhaust port, we must note that is in terms of installation or from choice, we must pay attention to some of its specifications set the parameters, because it is to decide whether the multi-leaf smoke vents can more efficient to play a key factor in their performance, let's look at specific: 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 mesh, B word bent by the wind calculations, calculation based on positive factory outlet duct meter extension does not require a separate set 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 the operating air pressure delivery outlet mechanism is intact, the action is flexible and effective. For more information about this knowledge we will continue to bring you organize. The correct steps leafy exhaust port is like leafy exhaust port makes use of electromagnetic decoupling electromagnetic suction force provided less smooth open the valve, and I produced the multi-leaf smoke vents were carefully designed, connecting rod assembly for hanging and a tension spring assembly has been improved, as the hanging rod assemblies are constituted by two levers, the electromagnetic force disengagement force only two rods normally closed pressure delivery outlet, extension spring is connected to the coupling plate on so many leaves greatly reduces exhaust port hanging rod assembly decoupling force. Leafy exhaust port combined with electric chain control device, plus building air, together form a complete exhaust system, which can effectively eliminate the smoke electric pressure delivery outlet, multi-leaf smoke vents in the configuration an aluminum air flow control valve, so it can regulate the proliferation of surface flow, leafy exhaust port in order to ensure the proper use of its functions are just right to show it.
