Pressure delivery outlet, also known as multi-leaf smoke vents stairwell pressure delivery outlet, pressure delivery outlet (multi-leaf smoke vents) in the construction of how to arrange it? Pressure delivery outlet (leafy exhaust port) installation, note the following two points: the first point: positive outlet (multi-leaf smoke vents) in the basement ventilation, the pressure delivery outlet (leafy exhaust port) reasonable arrangement of exhaust pipes and air vents, exhaust leafy exhaust port usually used, doubles exhaust duct and exhaust port when the fire; basement lanes naturally considered by the wind, the other layers from the air supply system usually doubles as a fire When up air system. Each exhaust, exhaust and air supply system should be set up silos positive outlet installation requirements, inlets should be located on the ground clean place, if there is a certain distance from the main building with ground floor better, it will be little affected by the gas fire; if with the ground some distance from the main building better pressure delivery outlet location, its impact will be little affected by the fire smoke, air vents should be located above the towers level, in order to reduce the impact on the ground environment exhaust. Outlet pressure of the five kinds of building an effective way to set in today, we want to give you an analysis focused on the pressure outlet of relevant knowledge, I believe that the knowledge which is the majority of users are more concerned about, let's look at specific about the pressure to send outlet in set building types, and hope that through our explanation so that everyone can better realize this: 1. Pressurized stairwell of the outlet should be used since the vertical louvers or positive pressure air outlet / multi-leaf smoke vents (body + panel form), when using positive pressure outlet (leafy exhaust port), should be set with an electric valve open fan chain on its pressure fan of the suction pipe. Method 2. Pre-pressurized chamber outlet should be opened or automatic fire alarm linkage NC Grille open for on-site manual. Method 3. Mechanical pressure blower can set one or more. Pressurized air supply room should adopt the fire resistance of not less than 2.5 hours and 1.5 hours of wall and floor separated from the other parts of the pressure delivery outlet, the door on the wall should be Class A fire doors. Method 4. Mechanical pressure outlet of the wind speed of not more than 7m / s. Outlet section stairwell stairwell by the average of the total air volume calculation, 50% of the outlet section of the front room by the front room of the total air volume. Method 5. Antechamber mechanical pressure outlet should be set in the wall near the ground for more knowledge about the pressure blower and we will continue to bring you to organize, so stay tuned.
