Fire dampers in several categories of products? Exhaust valves in several categories of products? Such valve located in the exhaust passage or a combination of dedicated ducts, according to smoke partition settings. There are three main kinds: exhaust valves: For use either branch duct smoke exhaust valve is normally open sub-region, and because of the uncertainty of the fire zone, Xinjiang damper, the exhaust valve and should be open, can be closed, damper structure, it should use electric. Either smoke partitions fire, fire dampers, fire control center can have open exhaust area exhaust valves, exhaust valves closed other partitions. If the smoke partition branch duct not use either, that in parallel with a dedicated primary air duct exhaust tube stop, then exhaust valve on the exhaust manifold is normally closed, and with the smoke detectors linked electromagnetic valve manual reset . General non-use either the exhaust system exhaust valve is also true. Exhaust port: the exhaust valve and Grille or plate outlet composition, temperature-controlled dampers, used in special rocket exhaust manifold exhaust system with the system. Smoke damper: the installation of the exhaust valve 280 ℃ temperature of the blown fuse constitutes smoke damper. When the exhaust gas temperature reaches 280 ℃, the temperature fuse action, the valve is closed, stop the smoke. In addition, in the dry exhaust pipe and exhaust fan shaft connection or through room walls should be located at 280 ℃ blown off dampers or fire control valve, in order to stop the fire from spreading.

Hao Yang smoke damper mounting position? Ventilation of the following circumstances, the air conditioning should be set on fire damper duct system: 1 through the fire district office; 2 through the ventilation, air conditioning room walls and floor of the room; 3 through major fire hazard or large 4 through deformation crack at the sides;; room wall and floor of the upper horizontal pipe 5 vertical wind pipe and duct junction of each level, but within each fire district building ventilation, air conditioning systems are provided independently When the horizontal and vertical duct manifold junction of the sub-region may set the fire dampers.
