The invention relates to the technical field of ship construction, and discloses a beveled suction port of a ship ballast tank, which is characterized in that a pipeline (2) in the tank is bent from a tank wall (74) to a tank bottom (4); the suction port end, at the cabin (3), of the in-cabin pipeline (2) is a beveled suction port; the oblique section of the beveled suction port is parallel to a tank bottom (4) of the ballast tank with an angle of inclination of a degrees, and the outlet end of the in-tank pipeline (2) penetrates out of a tank wall (74) of the ballast tank; a cabin door (7) is arranged on the cabin wall (74); a locking switch (71) is arranged on the cabin door (7); sealing rubber strips (73) are fixed on the periphery, connected with the cabin wall (74), of the cabin door (7), and a distance H is formed between the suction port end and the cabin bottom (4) of the ballast tank; . On the premise that related requirements of the suction port are met, the suction port can be closer to the cabin bottom, more space can be saved in the ballast tank layout, the space utilization rate in the ballast tank is guaranteed, the pressure condition of a pipeline port can be reduced, and cavitation of the pipeline suction port is reduced.
本发明涉及船舶建造技术领域,公开了一种船舶压载舱斜切式吸口,其舱内管路(2)由舱壁(74)向舱底(4)方向弯折;舱内管路(2)在舱室(3)的吸口端为斜切式吸口;斜切式吸口的斜截面与具有a°倾斜角的压载舱的舱底(4)平行,舱内管路(2)的出口端穿出压载舱的舱壁(74);舱壁(74)上开设舱门(7);舱门(7)上设有锁紧开关(71);舱门(7)与舱壁(74)连接的四周固定有密封胶条(73),吸口端与压载舱的舱底(4)之间设有间距H;。本发明在满足吸口相关要求的前提下可以更靠近舱底,在压载舱布局中可节省更多的空间,不仅保证了压载舱舱室内的空间利用率,还能减少管路端口的受压情况,减少管路吸口的汽蚀。
