Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust valves, in particular to a smoke exhaust valve which is convenient to disassemble. Background Technique

[0002] With the progress of technology and the development of society, more and more fire dampers are installed in buildings for protection. During a fire, the sensor on the fire damper can sense and close the valve to block the fire source, thus achieving isolation protection. The smoke exhaust valve is a device to prevent the spread of fire, and the smoke exhaust valve is normally in an open state. In general buildings, it is usually installed at the inlet of the fan shared by the smoke exhaust system and the ventilation and air conditioning system. After a fire breaks out, when the air flow temperature in the pipeline rises to make the fuse easy to melt, the core rod is pushed by the spring, disengaging the fork plate, and the valve shaft rotates under the action of the torsion spring to close the valve, and meets the requirements of smoke leakage and fire resistance integrity within a certain time, playing a role in isolating smoke and blocking fire. The main materials are: carbon steel, galvanized sheet, stainless steel.

[0003] In the building smoke prevention and exhaust system, the smoke exhaust valve is a crucial component. Most of the existing smoke exhaust valves usually require professional tools and complex operation procedures for maintenance, repair or replacement, greatly increasing the maintenance cost and reducing the work efficiency; therefore, we propose a smoke exhaust valve which is convenient to disassemble to solve this problem.
