Utilize280°F fire damperFire safety is a highly regarded issue in our daily lives.280°F fire damperThe presence is to eliminate fire risks and prepare for the occurrence of fires. Then we utilize280°F fire damperWhat are the considerations to keep in mind? This is something many people want to understand. Today, our factory will specifically introduce to you.280°F fire damperConsiderations to be addressed. Let's take a look at the specific situations.280°F fire damperFor ductwork in ventilation and air conditioning systems that require smoke and fire prevention, highly suitable for critical buildings equipped with halon gas fire extinguishing systems. Suining 280-degree fire dampers, as they require all valves to be closed prior to releasing gas for extinguishing, and after completion of extinguishing, the valves should be opened for ventilation and exhaust.
1、280°F fire damperValve smoke leakage is on the rise, possibly due to the mechanical strength of the blades reaching its limit when the furnace temperature increases to a certain value. As the test progresses, the degree of deformation of the blades continuously increases, and the gaps between the blades and the outer frame, as well as between the blades themselves, also expand, leading to an increase in valve smoke leakage. Additionally, the decrease in the elastic force of the spring under high temperatures may also cause an increase in valve smoke leakage. 2,280°F fire damperValve smoke leakage is on a decreasing trend; at the 280-degree fire valve base, this may be due to the incomplete deformation process of the blades, as the mechanical strength of the blades has not yet reached its limit, allowing for continued decrease in the valve's smoke leakage.
280°F fire damperWhere is a 280-degree fire damper used, and there are two types: normally open and normally closed.280°F fire damperWhy differentiate between 70℃ and 280℃? Why does the 280℃ setting have both open and closed options? First, it's important to understand the types of supply air ducts and exhaust ducts. Supply Air Ducts: These include the supply air ducts in ventilation systems and the supply air ducts in air conditioning systems. Exhaust Ducts: These encompass the exhaust air ducts in ventilation systems and the smoke exhaust ducts in smoke exhaust systems. The equipment in the supply air ducts operates at 70℃.280°F fire damperFor normal operation, in the event of a fire,280°F fire damperThe facility would be sealed. Imagine, if there's a fire, supplying air is just delivering oxygen, which would only make the fire worse. Therefore, 70°C is a relatively reasonable test standard, as too low a temperature may risk improper sealing, and too high a temperature might exacerbate the fire.
