Abstract

The invention discloses a flange structure for butt joint of pressure-resistant cabin sections of underwater special equipment and a mounting method thereof. The flange structure for butt joint of the pressure-resistant cabin sections of the underwater special equipment comprises a large-end butt joint flange and a small-end butt joint flange which are located on the inner sides of the two pressure-resistant cabin sections respectively; a boss extending towards one side of the small-end butt joint flange is arranged on the inner ring side of the large-end butt joint flange, and the boss is arranged on the inner ring side of the small-end butt joint flange in a sleeving mode; a groove is formed in the outer ring side of the small-end butt joint flange, the connecting bolt penetrates through the side wall of the groove and then is in threaded connection with the large-end butt joint flange; and the groove of the small-end butt joint flange is covered with a cover plate used for sealing the opening side of the groove of the small-end butt joint flange. According to the flange structure for butt joint of the pressure-resistant cabin sections of the underwater special equipment, on the premise that the butt joint flanges are disassembled and assembled outside the cabin, the smoothness of the outer surfaces of the pressure-resistant cabin sections can be guaranteed. The flange structure for butt joint of the pressure-resistant cabin sections of the underwater special equipment is simple in structure, convenient to disassemble and assemble and excellent in sealing and anti-corrosion performance.

Description

technical field [0001] The invention relates to the field of underwater special equipment, in particular to a flange structure for butt jointing of pressure-resistant cabin sections of underwater special equipment and an installation method thereof. Background technique [0002] Butt joint flanges are provided on the pressure-resistant compartment of underwater special equipment, which can divide the whole special equipment into multiple detachable compartment modules, so as to facilitate the modular construction, modification, installation and maintenance of special equipment. [0003] At present, in the conventional butt joint flange structure, if the installation surface of the flange is facing the cabin, people need to enter the cabin for installation, and the installation space and access hatches need to be reserved; if the installation surface of the flange is facing the outside of the cabin, The connecting bolts and sealing structure will protrude from the outer surfa...
