Smoke exhaust heat insulation airtight penetration assembly and ship containing it

Abstract

The invention discloses a smoke exhausting thermal insulation airtight run-through component and a ship comprising the smoke exhausting thermal insulation airtight run-through component. The smoke exhausting thermal insulation airtight run-through component comprises a smoke exhaust pipe penetrating into a run-through hole of a deck, the outer portion of the smoke exhaust pipe is sleeved with a connecting sleeve, the inner wall of the connecting sleeve and the outer wall of the smoke exhaust pipe are spaced, the outer wall of the connecting sleeve and the inner wall of the run-through hole arespaced, the outer wall of the connecting sleeve is provided with a fixing reinforcing plate for sealing a gap between the outer wall of the connecting sleeve and the inner wall of the run-through hole, the fixing reinforcing plate is welded to the deck, and a sealing thermal insulation layer is arranged between the inner wall of the connecting sleeve and the outer wall of the smoke exhaust pipe.Through the above design, heat in the smoke exhaust pipe can be transmitted to the deck to the minimum degree, the sealing thermal insulation layer achieves effective thermal insulation and improves asealing effect, water outside the deck cannot enter a cabin, the air tightness and the water tightness in the cabin are guaranteed, the fixing reinforcing plate can support the connecting sleeve andseal a gap between the connecting sleeve and the deck as well, and meanwhile, an opening of the deck is reinforced.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a smoke exhaust heat insulation airtight penetration assembly and a ship containing the same. Background technique [0002] At present, smoke exhaust pipes are usually installed on ships, and the fixing method of the smoke exhaust pipes is mainly: a through hole is opened on the deck, the smoke exhaust pipe passes through the through hole and is connected to the deck in a non-welding manner, and then passes through the smoke exhaust pipe. The way of adding a hoop around the outer circumference of the pipe prevents the rainwater on the deck from falling into the next deck through the opening. The existing method of fixing the smoke exhaust pipe has the following defects: 1. The non-welding method fixes the smoke exhaust pipe, so that the fixed position of the smoke exhaust pipe cannot meet the airtightness requirements of different pressure gradients between different deck layers; ...

AI Technical Summary

Problems solved by technology

The existing method of fixing the smoke exhaust pipe has the following defects: 1. The non-welding method fixes the smoke exhaust pipe, so that the fixed position of the smoke exhaust pipe cannot meet the airtightness requirements of different pressure gradients between different deck layers; Fire rating requirements for pipes passing through airtight (watertight) decks and wall panels
