Fan coil units, air, LCD thermostat, glass blower fvd fire dampers, air flow control valve, Air Conditioning Equipment Co., Texas Hao Yang fire dampers in several categories of products? Exhaust valves in several categories of products? Such valves located in a dedicated channel or a combination of exhaust ducts, according to smoke partition settings. Mainly in the following three kinds: exhaust valves: For use either branch duct smoke exhaust valve is normally open sub-region, and because of the uncertainty of the damper structure fire district, the exhaust valve should be open again can be closed, it should adopt electric. Either a smoke partition fire, the fire control center in the area can have a smoke exhaust valve opens, the other partitions exhaust valves closed. If the smoke partition not use either branch duct, the duct that is in parallel with a dedicated primary exhaust pipe only, then the exhaust valve on the exhaust manifolds are normally closed, and with the smoke detectors linked electromagnetic valve manual reset . General non-use either the exhaust valve exhaust system is also true. Exhaust port: the exhaust valve and outlet composition Grille or plate with special exhaust manifolds on the rocket exhaust system with the system. Smoke damper: the installation of the exhaust valve 280 ℃ temperature fuse blown constitutes smoke damper. When the exhaust gas temperature reaches 280 ℃, the temperature fuse action, the valve closes simple damper, stop smoke. In addition, in the dry exhaust pipe and exhaust fan shaft connection or through the wall of the room should be located 280 ℃ blown off dampers or fire control valve to stop the fire from spreading.
