Description

technical field [0001] The invention provides a fire damper, in particular to a marine hand-operated electric remote control fire damper. Background technique [0002] Fire dampers are usually installed on marine ventilation ducts. Traditional fire dampers use manual or electric switches. However, when the environment of the ship is unpredictable, a separate switch structure is used, which may cause the hidden danger of being unable to switch after damage. Contents of the invention [0003] The invention provides a comprehensive manual, pneumatic and electric control, which can effectively ensure one use and two preparations, and a marine hand-operated electric remote control fire damper with high safety performance. [0004] The technical solution adopted in the present invention is: a marine handheld electric remote control fire damper, including a valve body, a valve plate, a connecting rod, a valve plate shaft and a fusible piece tube assembly. The valve plate shaft, ...
