Ye exhaust port (outlet pressure) PYK-2-Ⅰ PYK-2-Ⅱ applicable leafy exhaust port is usually installed in the front room on the aisle or smoke and exhaust system of the room without windows. Outlet pressure mounted smoke before the interior pressure outlet, the former interior positive pressure when the fire broke. Performance control devices with SD Specification positive outlet, power DC24V, 0.5A. Usually normally closed, when an electrical signal to the control center DC24V open. Manually open, manual reset. Open the valve operation output signal. You can interlock with other devices based on user demand. Suitable for multi-leaf fire exhaust port PYK-5-Ⅰ PYK-5-Ⅱ multi-leaf smoke mouth usually installed fire or smoke in the hallway in front of the room, windowless room and exhaust systems. When the flue gas temperature reaches 280 ℃ automatically re-close, in order to achieve the purpose of fire protection. Performance using SFD control device, the power outlet positive role DC24V, 0.5A. Usually normally closed, when an electrical signal to the control center DC24V open. Manually open, manual reset. Open the valve operation output signal. You can interlock with other devices based on user demand. When the temperature reaches 280 ℃ automatically re-closed. How will the pressure outlet properly installed in the building? Current Position: Home> NEWS outlet pressure has a very good use of effects in the building, the construction of essential goods. Construction of the installation, the installation of outlet pressure is relatively simple, but simple, but can not ignore the positive outlet face, below, to learn together under pressure outlet of the correct installation of it. Method One, pressurized stairwell of outlet should be self-hanging type Grille or positive outlet / multi-leaf smoke vents (body + panel form), when using positive pressure outlet (leafy exhaust port ), the chain should be provided with open fan motor-operated valve on its pressure fan of the suction pipe. Method two, ventricular pressure outlet should be opened or automatic fire alarm linkage NC Grille open for on-site manual. Method three, 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 IV, ventricular mechanical pressure outlet should be set in the wall near the ground. Five methods, 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 separated from the other parts of the floor, the door on the wall should be Class A fire doors. Outlet pressure air supply equipment has now become an essential major buildings, the outlet of the application brought us a more comfortable environment. Effective pressurized air outlet is set in a building, it can really be safe.
