Detachable watertight fireproof and heat insulation cabin penetration part

Abstract

The invention provides a detachable watertight fireproof and heat insulation cabin penetration part which comprises a connecting flange A, a cylinder, a fixed seat plate, sleeves, a positioning fastener and a top plate. The connecting flange A is welded and mounted at one end of the cylinder, a connecting flange B is welded and mounted at the other end of the cylinder, a mounting footing is weldedand fixed to the middle position of the cylinder, the mounting footing is provided with a fireproof and heat insulation gasket and the fixed seat plate successively through a fixed bolt and a screw,the sleeves are fixed to two sides of the mounting footing, and an overhaul cover plate is hermetically mounted on the sides, far away from the mounting footing, of the sleeves through the positioningfastener and a fixed part. According to the detachable watertight fireproof and heat insulation cabin penetration part, heat can be prevented from being conducted to the fixed seat plate and a cabinwall of a ship through the fireproof and heat insulation gasket made from a material with low heat conductivity coefficient, so that a heat insulation effect is exerted, and deformation of the cabin wall of the ship due to high temperature is prevented.

Description

technical field [0001] The disclosure relates to the technical field of watertight cabins of ships, in particular to a detachable watertight fireproof and heat-insulating cabin member. Background technique [0002] When the ship is sailing at sea, the main generator set or main diesel engine in the engine room area of ​​the ship is under operating conditions, and the fuel is burned in the main generator set or main diesel engine cylinder, which will generate a large amount of exhaust gas. The fuel in the main generator set or the main diesel engine cannot be fully burned 100%, so the exhaust gas produced contains a lot of heat. By designing the exhaust pipe to be connected to the exhaust port on the main generator set or the main diesel engine, a large amount of exhaust gas generated by the main generator set or the main diesel engine is discharged to the outside through the chimney area. The smoke exhaust pipe is generally made of steel pipe or stainless steel pipe, which ...

AI Technical Summary

Problems solved by technology

[0004] 1. In the existing technology, the general steel pipe penetrations (double plate penetrations and casing penetrations) will conduct the heat on the smoke exhaust pipe to the connected fireproof watertight bulkhead, and connect with the smoke exhaust pipe The area near the fire-resistant watertight bulkhead will have a relatively high temperature, resulting in a large amount of thermal stress and thermal expansion, accompanied by thermal deformation, posing a threat to the safety of the ship

[0005] 2. The existing technology is not easy to disassemble during use, which will bring great inconvenience to the staff during use and maintenance, and the internal heat insulation material cannot be conveniently and quickly installed on the device when the device is installed. interior, thereby affecting the fire and heat insulation performance of the unit
