Fire dampers are used in the supply and return air ducts of ventilation and air conditioning systems. They are usually in an open state, and once a fire occurs, when the temperature of the gas in the duct reaches 70 ℃, they will automatically close and meet the requirements of fire resistance stability and integrity within a certain period of time, playing a role in smoke and fire prevention. The 3C smoke exhaust fan is a mechanical device that can quickly remove odors, high temperatures, and cooking fumes generated during food processing in the kitchen. The machine is characterized by good high-temperature resistance and high efficiency. The smoke exhaust valve is used on the smoke exhaust system pipeline or the suction port of the smoke exhaust fan. It is usually in a closed state. When a fire occurs, the valve is manually or automatically opened through a fire alarm signal. According to the system function, it cooperates with smoke exhaust. When the temperature of the smoke in the pipeline reaches 280 ℃, it automatically closes and can meet the requirements of fire stability and fire integrity for a certain period of time, playing a role in smoke isolation and fire resistance.
        Fire dampers and smoke exhaust valves play an important role in ventilation, air conditioning, and smoke control systems. Low noise axial flow fan is an indispensable key equipment in the kitchen. It is recommended not to install it in the ceiling as much as possible, but to install it in places such as computer rooms, roofs, or exterior walls that are easy to maintain. The main control parameters selected for the 3c smoke exhaust fire damper are operating temperature, air volume, total pressure, efficiency, noise, motor power, speed, and shaft power. Fire dampers include (b ā o kuò) gravity type fire dampers, fire control valves (using materials such as cast iron, cast steel, stainless steel, etc.), fire vents, pneumatic fire dampers, smoke dampers, electronic self-control smoke dampers, and other products; Smoke exhaust valves include smoke exhaust fire dampers, plate type smoke exhaust outlets (for ceilings), smoke exhaust outlets for vertical shafts, and other products. Fire dampers and smoke exhaust valves are important components in ventilation, air conditioning, and smoke control systems. They play an important role in the system by demonstrating their inherent capabilities, mainly in the following three aspects: ventilation: mainly engaged in the design and processing of ventilation ducts. Galvanized plates range from 0.5mm to 1.2mm, equipped with air duct production lines and plasma cutting equipment. Welcome to visit and negotiate at Gate 1 of Pingyuan Road Steel Market, 80 meters south of Road East. Simultaneously undertake ventilation and smoke exhaust projects for various basements, large and medium-sized supermarkets, and hotels.
