Automatic fire dampers and smoke exhaust valves stand as pivotal safety instruments embedded within buildings, offering protection against the menacing spread of fire and smoke during emergencies. Ingeniously designed, automatic fire dampers close seamlessly upon receiving signals from fire alarms or heat detectors. Securely positioned within HVAC ducts, they serve as a formidable barrier, thwarting fire and smoke from pervading different building areas. Vital to compliance with building codes, these dampers undergo rigorous testing and inspection to guarantee optimal functionality. In parallel, smoke exhaust valves diligently expel smoke during fires, their precision control systems detecting rising smoke levels. Strategically placed within ducts, they prevent smoke build-up in escape paths and critical zones, facilitating safe evacuation and firefighting efforts. Together, both automatic fire dampers and smoke exhaust valves are indispensable in safeguarding lives and mitigating fire and smoke proliferation. Their installation, maintenance, and regular testing are imperative to ensure readiness in times of need.
Fire dampers diversify into various configurations to suit specific functions: smoke exhaust valves, smoke exhaust fire dampers, fire control valves, and versatile smoke and fire control valves. The smoke exhaust valve is astutely situated within the smoke evacuation systems of towering and subterranean structures, equipped for synchronized temperature (smoke) signal response, triggering the smoke exhaust fan instantaneously alongside manual valve operation signals. The smoke exhaust fire damper, purpose-built for smoke and fire deterrence, activates upon sensing an exhaust temperature exceeding 280, thereby sealing the valve and halting the smoke exhaust fan. The fire-proof regulating valve, affixed to fire-resistant ventilation and air-conditioning pipelines, responds by sealing the valve at 70, emitting valve closure signals, and ceasing fan operation while allowing seamless air volume modulation. The smoke and fire-proof regulating valve, integrated within smoke and fire-resistant systems, ensures synchronized closure with smoke (temperature) signals, manual operations, and 70 fuse activation, delivering closure signals and facilitating stepwise air volume adjustments through 90° five equal segments.
