Description

Technical Field

[0001] The utility model relates to the technical field of ship ventilation, in particular to a ship spiral air duct component. Background Art

[0002] Spiral ducts are widely used in ship superstructure air conditioning and cabin ventilation due to their light weight and easy installation. When the spiral duct passes through the bulkhead or deck, a spiral duct cabin pass will be used. The cabin pass is welded to the deck or bulkhead, and the two ends are connected to the spiral duct through internal joints, and the interface is sealed with sealing tape. The spiral duct is connected with accessories such as tees, elbows, and reducers. When installing, the tees, reducers, and elbows are directly inserted into the spiral duct, and the interface is sealed with tape. Since the spiral duct is made of galvanized iron sheets, the wall thickness is very thin, generally 0.5-0.6mm. During the installation process, due to construction errors, there is deformation and dislocation, which causes air leakage at the interface. The cabin pass, tees, elbows, reducers and other accessories are easy to fall off at the connection with the duct over time. Leakage or falling off of the duct will lead to insufficient cabin ventilation, affecting the quality of life of the crew. Moreover, if the spiral duct and its accessories fall off, it will directly threaten the life safety of the crew. In order to solve the above problems and ensure sufficient ventilation in the cabin and the safety of the crew, a connection method for the spiral air duct of the ship and its accessories is urgently needed to supplement the deficiencies of the existing cabin ventilation parts.
