Wall-passing type fire damper mounting structure

Abstract

The invention provides a wall-passing type fire damper mounting structure. The wall-passing type fire damper mounting structure comprises fixing screws, connecting frames, sliding rods, movable seats, sliding blocks, springs, rolling grooves, rolling wheels and steel sleeves, wherein the connecting frames are assembled on the left side and the right side of a fire damper body, the fixing screws are assembled in the connecting frames, the steel sleeves are assembled on the annular side faces of the fixing screws, the movable seats are mounted on the inner sides of the connecting frames, the sliding rods are assembled on the left sides and the right sides of the movable seats, the springs are assembled on the inner sides of the sliding rods, the sliding blocks are assembled in the middles of the sliding rods, the rolling wheels are assembled on the left sides of the sliding blocks, and the rolling grooves are formed in the connecting frames. The problem that an original fireproof valve does not have the flexible buffering effect is solved through the wall-passing type fire damper, and the fire damper is reasonable in structure and facilitates effective buffering and airflow influence balancing.

Description

technical field [0001] The invention relates to an installation structure of a through-wall type fire damper, which belongs to the technical field of fire dampers. Background technique [0002] The fire damper is a normally closed valve plate, which is opened by the control center through 24V DC or manually, and it will automatically close at 280 °C, and the reset must be done manually. Its function is: when the temperature of the flue gas reaches 280°C, the evacuation of the people has been basically completed, and the smoke exhaust has no practical significance. At this time, the flue gas is already on fire, and the valve plate is automatically closed to avoid the spread of the fire. The smoke exhaust outlet of the system can also use a normally closed fire-proof smoke exhaust outlet, and the smoke exhaust fire damper on the branch pipe is cancelled. In the event of a fire, the air outlet is opened by the control center through 24V DC or opened manually. When the smoke te...

Problems solved by technology

[0003] In the past, because the fire damper did not have a buffer structure, it was easily deformed by the impact after encountering the impact of high-temperature gas. Because it did not have the function of airflow balance, it could not guide the air well when it encountered the influence of unbalanced airflow. The valve does not have a flexible buffer effect, and now there is an urgent need for a wall-mounted fire damper installation structure to solve the above problems
