The existence of smoke exhaust fire damper is to eliminate fire risk and prevent fire from happening. It is generally installed on the smoke exhaust pipeline of mechanical smoke exhaust system to prevent smoke and fire. Fire damper is a kind of valve form that remembers the temperature control of molten alloy and closes by gravity and spring mechanism. Some new products also use the shape memory alloy to close the valve. Its function is: when the temperature of flue gas reaches 280℃, people have basically evacuated, and it is of no practical significance to smoke. However, there is fire in the flue gas at this time, and the valve automatically closes to avoid the spread of fire. What should we pay attention to in the process of using smoke exhaust fire damper? Here is a small series to give you a simple description of its related knowledge points.

When the smoke exhaust system is also used as ventilation air conditioning system, it is necessary to consider not only the requirements of air dispatching during ventilation, but also the requirements of sensitive smoke exhaust and fire prevention in case of fire. In addition, the smoke exhaust fire damper is also suitable for occasions where ventilation and air conditioning pipes are installed on the ceiling and cannot be manually reset. Circular fire damper and smoke exhaust fire damper are suitable for the air ducts of ventilated air conditioning systems with smoke prevention and fire prevention requirements, and are very suitable for important buildings with halon gas active equipment. Because all valves are required to be blocked before releasing gas, after the rescue, the valves should be opened for ventilation and exhaust.

Smoke exhaust fire damper is an important part of the active system, which is installed in the field to control the flow path, so it is an important equipment to block the flow path and prevent flammable fluid from leading to the fire. In case of fire, it is very important whether the smoke exhaust fire damper is opened or blocked. It is worth noting that the smoke exhaust fire valve is controlled by the dispatcher in the control room, not manually operated. Therefore, the important characteristics of the smoke exhaust fire valve should be: it can endure temperature adjustment for a short period of time, or it should make the leakage less when it is blocked.

The standard of fire control valve should adjust the stuffing box and other sealing parts of the control valve, replace the sealing parts when necessary, and adhere to the sealing performance of static and dynamic sealing points. Add lubricating oil to the parts to be lubricated. Sewage and clean the air source or hydraulic filtration system. Check the connection and erosion of each connection point, and replace the connector if necessary.

General technical parameters of fire prevention and smoke exhaust valve series products: The valve frame and blades are made of galvanized steel plate, without solder joints, and the bearing material of air valve is sintered bronze oil-bearing which can withstand the high temperature of 300oC, without protecting the valve body thickness scale L=200mm, and can also produce various special scales according to customer requirements.
