Working principle of plate type smoke exhaust outlet - precautions for plate type smoke exhaust outlet
The installation of the plate type smoke exhaust outlet needs to pay attention to its direction, and the fusible parts should face the airflow direction. After installation, conduct action tests and ensure that the valve plate can be opened and closed flexibly and reliably; When the diameter or side length of the plate type smoke exhaust outlet is greater than or equal to 630mm, independent supports and hangers shall be installed; The plate type smoke exhaust outlets on both sides of the fire compartment partition should not be more than 200mm from the wall surface. The installation direction of the check valve should be correct. The installation height of the panel type smoke exhaust outlet wall actuator is between 1200-1500mm. The vertical part of the JDG pipe with the steel wire rope configuration should be vertical, and the bending of the joint with the actuator mouth should be curved, without distortion or stepping, to ensure a beautiful appearance and smooth expansion and contraction of the steel wire rope. In short, when installing a plate type smoke exhaust outlet, attention should be paid to ensuring the installation direction of the air outlet, the installation height, and the fire prevention treatment at the connection with the air duct to ensure the functionality of the fire prevention system.
