Technical Field

[0001] This utility model relates to the field of smoke exhaust valve technology, specifically a structure for an underground civil defense smoke exhaust valve. Background Technology

[0002] Smoke exhaust valves are installed at the ends of each branch pipe of the mechanical smoke exhaust system. They are normally closed and meet the air leakage requirements. They are opened when there is a fire or when smoke needs to be exhausted. The installation and use of smoke exhaust valves are especially important in underground civil defense projects.

[0003] An existing underground civil defense smoke exhaust valve structure (CN202421255012.4) uses a dust filter screen in conjunction with an outer casing. The dust filter screen inside the casing filters the incoming and outgoing smoke, preventing dust particles from being discharged and providing a good limiting effect.
