Description

Technical Field

[0001] The utility model belongs to the technical field of ship pipe fittings, and more specifically, it relates to a structure for a ship high-pressure pipe fitting to penetrate a cabin wall. Background Technique

[0002] On a ship, high-pressure pipe fittings are required. When arranging high-pressure pipe fittings, they need to penetrate the cabin wall for arrangement. In the prior art, the high-pressure pipe fittings are fixed on the cabin wall and cannot be disassembled. After the high-pressure pipe fittings are used for a period of time, they need to be disassembled for wall thickness detection to ensure safe use. The high-pressure pipe fittings in the prior art do not have the property of being detachable. Even if they are disassembled, it will cause damage to the pipe fittings and the cabin wall, and the arrangement and disassembly of the high-pressure pipe fittings are extremely troublesome, resulting in high labor intensity for personnel.

The through-cabin component includes: a through-cabin pipe fitting that can penetrate the cabin wall; a first connecting flange provided at the first end of the through-cabin pipe fitting; a second connecting flange operably provided at the second end of the through-cabin pipe fitting. The second connecting flange is composed of a first flange portion and a second flange portion, and the first flange portion and the second flange portion are detachably connected. For the through-cabin component provided in this application, when the through-cabin pipe fitting penetrates the cabin wall, it penetrates the cabin wall from the second end of the through-cabin pipe fitting. After the second end of the through-cabin pipe fitting passes through the cabin wall, the first flange portion and the second flange portion are respectively assembled onto the flange at the second end of the through-cabin pipe fitting, and the first flange portion and the second flange portion are connected, thereby assembling the second connecting flange. In this way, the second connecting flange does not need to penetrate the cabin wall, so there is no need to open a large-sized hole in the cabin wall for the second connecting flange to pass through, and only the flange needs to pass through, ensuring the structural strength of the cabin wall.

[0004] However, this technology does not involve the technical problems and technical solutions of this application. Content of the Utility Model
