With the continuous improvement of pressure delivery outlet widespread application of technology we know of each product produced, its use can play a certain role, and then arrived at the user's demand for the use of the pressure delivery outlet, too, for its use as a fire division, its internal electric actuator will open the outlet, temperature sense smoke or fire alarm is manually opened, the tower top positive pressure fan will automatically open, multi-page pressure delivery outlet of air shafts were pressurized air, fire pressure delivery outlet, the front chamber of the stairs through a steady stream of pressurized air outlet will be on air before the chamber, pressure delivery outlet, so that the former adhere to a positive pressure chamber to ensure that smoke does not extend in this area, while giving space to escape. When the temperature is higher than 280 ° C person has no possibility of escape, the internal fuse will blow, vent automatically shut down to prevent the fire extending. Follow technology continues to improve, the pressure delivery outlet can be widely used in the production of the following situations: 1, do not have the natural conditions of stairwell smoke, fire elevator room or shared room. 2, the use of natural smoke the stairwell, it does not have the front room of natural smoke. 3, closed fled layer. Several more cases can apply positive pressure air delivery device, about the use of their knowledge, the electric pressure delivery outlet, temporarily introduce us here, if you narrate to the above, there are other not understood locally, can outline consult our professional staff, we'll do satisfy reply. Outlet pressure calculations title label: Division I explain to you today is about the outlet pressure calculation problem. Outlet pressure during the calculation, first before the stairwells and pressurized air chamber as a whole to deal with smoke, it can not be considered in isolation smoke subject; secondly analysis should also pay attention to the stairwell, front room Changes in the closed and open state of the pressure, should not blindly apply a formula. Talk about the views of the steps and methods related to the calculation of the amount of pressurized air below. Above were sent to the participants in accordance with the pressing practical problems encountered in the work of the air gathered from, for reference, if you have questions, please communicate with correction.
