Abstract

The invention relates to a cabin penetrating device, which comprises a cabin penetrating sleeve, a cabin penetrating pipe and at least one locking joint, wherein the cabin penetrating sleeve axially penetrates through a cabin wall and is hermetically fixed on the cabin wall, the cabin penetrating pipe axially penetrates through the cabin penetrating sleeve, the locking joint is provided with a through hole, the through hole is at least partially arranged on the cabin penetrating pipe in a sleeved manner, the locking joint is abutted against an axial end surface of the cabin penetrating sleeveso that the cabin penetrating pipe can be fixed into the cabin penetrating sleeve in a sealed mode, and a connecting structure is arranged on the locking joint and used for connecting the locking joint with an external mechanism in a sealed mode. According to the cabin penetrating device, a common stop valve or a ball valve can be used for replacing a special right-angle stop valve with a bottom flange, the application object of cabin penetrating of the side of a high-pressure cabin pipeline is expanded, and the usage cost is reduced. According to the device, sealing rings are arranged at different positions so that mutual leakage of media inside and outside the high-pressure cabin and media inside a pipeline is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of pipe joints, in particular to a tank piercing device. Background technique [0002] Underwater equipment such as submarines or deep submersibles are usually equipped with pressure-resistant shells to isolate the interior of the deep submersible from external pressure seawater to ensure the normal operation of internal equipment and personnel. Part of the equipment outside the pressure shell usually requires fluid media such as pressure water and pressure oil provided by internal related equipment to drive the action of external equipment and complete related operations. Therefore, it is necessary to drill holes in the pressure-resistant shell to penetrate the pipeline, so that the fluid medium can enter the cabin or flow back into the cabin through the pipeline. In the related art, a welded seat plate is usually welded on the pressure-resistant body, and a right-angle stop valve with a bottom flange is i...
