Composition and role of electric leafy exhaust port analysis are here: Home> Technical Documents Electric leafy exhaust port generally includes a valve body components, valves, bushings, thin actuators grille panel. Leafy exhaust port is usually installed in the front room on the aisle or smoke and exhaust system of the room without windows. Electric multi-leaf smoke vents installed in the smoke before the interior pressure blower, former interior positive pressure when the fire broke out. Electric multi-leaf smoke vents with SD controls, power supply 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. Electric multi-leaf smoke vents in accordance with "fire protection design of tall buildings" in the requirements for building height does not exceed 50m in a class of public buildings and building height not exceeding l00m houses, the best set of natural exhaust system. Smoke is a natural economic construction, simple to set up, easy to operate and maintain the exhaust system is also very convenient. However, some systems use natural smoke engineering in the design and construction process can not be carried out according to standard positive pressure blower manufacturers, led after the completion of the project, the construction of facilities for natural smoke and can not meet the requirements or do not have a fundamental role in smoke . In the structure and use of positive pressure blower has the use of features are here: Home> Technical Documentation positive pressure blower and layers of positive pressure blower damper linkage positive quality, generally dirty air from the bathroom, toilet and kitchen, and fresh air from the living room into the bedroom and other areas. Positive pressure valve opens when the initial fire blower function, start positive pressure blower, so that stairwells, elevator hall positive pressure state, generally dirty air from the bathroom, toilet and kitchen, and fresh air from the living room, bedroom and other areas to send into. 1. Compact structure, easy installation, reliable operation; the fans than the axial flow or centrifugal small size, can be directly connected with the duct in the case of the same amount of wind, air pressure, and horizontal or vertical installation, operation and easy to use Features. 2. Low noise: positive pressure blower housing is specially designed to greatly reduce the outflow of noise. Under the unit amount of wind, air pressure unit working conditions, than A sound level can be reduced 2-3dB (A), while in the case of low speed, get a higher fan pressure. In the mining industry, and senior civil ventilation system can replace the low-pressure centrifugal fan or replace the high-pressure axial fan silencer without requiring a lot of action.
