Simple exhaust pipe cabin-communicated part

Abstract

The invention relates to a simple exhaust pipe cabin-communicated part. The simple exhaust pipe cabin-communicated part comprises a single-face base plate, a sealing gasket and a middle flange. The single-face base plate is provided with a second through hole through which an exhaust pipe penetrates and a plurality of threaded holes distributed around the second through hole in the circumferential direction, the single-face base plate is welded to the cabin wall, and a first through hole is communicated with the second through hole. The middle flange is provided with a third through hole through which the exhaust pipe penetrates and a plurality of eyelets which are distributed around the third through hole in the circumferential direction and correspond to the threaded holes, the middle flange is arranged outside the exhaust pipe in a sleeved mode through the third through hole, and the middle flange and the exhaust pipe are welded together. The middle flange is connected with the single-face base plate through bolts, and the sealing gasket is arranged between the middle flange and the single-face base plate. According to the simple exhaust pipe cabin-communicated part, the maintaining convenience and separating sealing among cabin chambers can be guaranteed, the ship humanization design and the good cabin chamber layout can be facilitated, the simple exhaust pipe cabin-communicated part is manufactured fast, the technology is simple, construction and manufacture are convenient and fast, cost is low, and the simple exhaust pipe cabin-communicated part has the basic condition for the general popularization and application.

Description

technical field [0001] The invention relates to a simple exhaust pipe opening. Background technique [0002] With the development of ocean engineering, more ocean engineering vessels have DP function and are equipped with bow thrusters. Some offshore engineering vessels are equipped with a bow thruster diesel engine to drive the bow thruster. Because the exhaust pipe of the diesel engine driving the bow thruster generally needs to pass through the bulkhead and go to the chimney. Therefore, during the construction of the ship, it is necessary to arrange and install the exhaust pipe through the cabin reasonably to pass through the bulkhead and so on. However, ordinary steel pipe tanks are generally fixed and cannot be disassembled. If gas welding is used to cut the bulkhead, the strength of the bulkhead will be weakened, the paint coating will be damaged, and it will cause inconvenience to the ship's crew on board and subsequent maintenance; Sealing the cabin parts will aff...

AI Technical Summary

Problems solved by technology

However, ordinary steel pipe tanks are generally fixed and cannot be disassembled. If gas welding is used to cut the bulkhead, the strength of the bulkhead will be weakened, the paint coating will be damaged, and it will cause inconvenience to the ship's crew on board and subsequent maintenance; If the tank is sealed, it will affect the separation and sealing between the cabins, which cannot meet the design requirements of the ship
