Everyone knows the importance of fire dampers, so how can the installation of fire dampers be divided into positive and negative? What are the precautions for the installation of fire dampers? Let's learn with Xiaobian!

1. The fire valve is installed in the air duct system of the central air conditioner. Its working principle is that it is easy to control the temperature of molten alloy, and the valve is closed by the action of gravity and spring mechanism. When a fire breaks out, the flame invades the air duct, and the high temperature melts the fusible alloy on the valve, or makes the memory alloy deform to make the valve automatically close, which is used in the situation where the air duct runs through the fire zone.

2. The valve body can be installed vertically or horizontally. No matter how the blades are installed, they must be parallel to the ground. If the blades cannot be parallel to the ground, an order must be declared.

3. Smoke exhaust fire damper The fire damper should be installed in the duct section close to the wall or floor. The fire dampers on both sides of the partition wall of the fire partition should not be more than 200mm away from the wall surface, and the pipes and their insulation data within 2.0m on both sides of the fire damper should use incombustible data.

4. The air duct where the fire damper is installed shall be provided with a separate hanger, and the air duct and its thermal insulation materials within 2．0m on both sides of the fire damper shall be made of incombustible materials. When the fire damper is concealed, the installation part is provided with an access port for easy maintenance.

5. The outer surface of the connecting pipe between 3c fire damper and firewall should be made of refractory and heat insulation layer, and the electrical circuit should be protected by Ф20mm refractory protection pipe.

6. If the vertical exhaust pipes of bathrooms, toilets and kitchens in public buildings have not taken measures to prevent backflow, fire dampers shall be set on the branch pipes.
