Abstract

The invention provides a pneumatic and manual full-shading type chimney shutter, and belongs to the field of chimney shutters. The pneumatic and manual full-shading type chimney shutter mainly comprises a welding web plate, a window frame, blades, a linkage pull rod and a pneumatic control system, wherein the welding web plate is welded on a cabin; the window frame is fixed on the welding web plate through a fastener; the blades are fixedly connected with the window frame through rotating shafts, and are connected with the linkage pull rod through connecting rods I arranged on the middle parts of the blades; and the linkage pull rod is connected with an air cylinder in the pneumatic control system through a connecting piece. The pneumatic and manual full-shading type chimney shutter is characterized by also comprising shading slots with grooves, wherein the shading slots are positioned in gaps between the blades and the window frame; bulges towards the inner direction of the cabin wall are formed on the rims of the peripheries of the blades; and the bulges can be clamped in the grooves of the shading slots. A good shading effect is achieved; full shading function of the chimney shutter is guaranteed; the pneumatic and manual full-shading type chimney shutter has the advantages of saving air sources, saving energy and reducing emission, can be manually closed in a remote distance or a near distance under an emergency, and can be widely applied in the field of ship chimney shutters.

Description

technical field [0001] The invention relates to the field of chimney shutters, in particular to a pneumatic manual full-shading chimney shutter. Background technique [0002] The working requirements of the chimney shutters of the ship are: under normal conditions, they are always open to facilitate the exhaust and ventilation of the engine room; and when the engine room catches fire and releases CO 2 The shutters must be able to be closed in an emergency. At the same time, when the chimney shutters are required to be closed at the destination port, no light can be transmitted. This requirement is one of the main inspection items in the port state inspection (PSC inspection for short), and its main purpose is to ensure that all arrivals The foreign ships are seaworthy, do not pose pollution hazards, provide a healthy and safe working environment and comply with relevant international conventions. [0003] Due to the relatively large size of ship chimney shutters, it is no l...
