Smoke fire damper operating conditions to buy common sense

Release Time：2021-07-21

What is the operating condition of the smoke and fire dampers.
Generally, a fire damper should be installed at the front end of the fan in the smoke exhaust system, which is usually open. After a fire occurs, the smoke exhaust valve in a certain area opens to start the smoke exhaust machine. If the fire is not effectively controlled, the temperature of the smoke exhaust system is getting higher and higher after a period of time. Generally, the fire damper on the fire exhaust system is 280 degrees. When the temperature is reached, it will automatically fuse, the valve will automatically close, and stop the smoke exhaust the smoke automatically, discharge to the fire damper is the fire, the equivalent of combustion.
Installed on the air supply and return pipes of ventilation and air conditioning systems, it is usually open. When the gas temperature in the pipe reaches 70 ℃ in case of fire, the fusible sheet will fuse and the valve will automatically close under the action of torsion spring force. It can meet the requirements of fire-resistant stability and fire-resistant integrity within a certain period of time. When the valve is closed, it will output a closing signal.
For the fire valve and the corresponding accessories, we should have an effective understanding of it, after the fire valve using the relevant parameters we know to effectively purchase, so as to ensure that the products we buy are in line with the specifications we need, here, fire valve accessories manufacturers talk about some common sense of fire valve purchase.
First, because the fire damper is more suitable for our common ventilation and air conditioning system, it excludes the fire damper that needs to be used in the kitchen fume exhaust system. We had better not exceed 150 ℃ for the ambient temperature. The temperature of the fire damper is usually about 70.
Second: because the fire valve is more suitable for ventilation and air conditioning and other piping systems, so its basic function is basically the same as our common exhaust valve.
Finally, fire valve accessories manufacturers want to say that when we choose the valve, we had better pay close attention to the function of the valve, for example, whether the valve is normally closed or automatically closed, or whether it needs to be manually closed and opened.
