Electric Sealed Fire Damper
Electric sealed fire dampers, like other fire dampers, are installed on the pipelines of air conditioning systems. Their control mechanism is the FS24 or FS220 electric spring reset mechanism imported from Switzerland. Unlike traditional fire dampers, when a fire occurs, the power supply is cut off and the valve is immediately closed by the reset spring. The valve is always in an energized state with low electrode consumption. After closing, there are two types of signals: signaling and non signaling. When powered on, the valve can be reset. The control mechanism of this valve can be installed to form fire dampers, smoke exhaust valves, and can also be used on air volume regulating valves. It can be manually operated and reset.
Overview
Composition of main components:
The main components include valves, blades, blade shafts, shaft sleeves, temperature fuses, controllers, etc. The valve body and blades are both made of steel plate material. The blades are stamped and formed, and the valve body is machined. Copper shaft sleeves are selected, and reliable temperature fuses and electric control actuators are used.
