The invention discloses a marine pipeline flange with a sealing structure. A butt flange is arranged on one side of a fixed flange, a driven pipe is connected to the middle of the side wall of one side of the butt flange, a threaded column is connected to the butt flange and is connected in a threaded groove by a thread, a threaded rod is connected to a telescopic column, a mounting groove is formed in the middle of the inner part of the telescopic column, and the end, located in the mounting groove, of a screw is rotatably connected to a clamping plate. A telescopic motion of the telescopic column can be controlled effectively by the spring, and the connecting stability and the sealing property can be improved effectively through the threaded column, the threaded groove and the sealing property, so that excellent end stability of the pipeline in vibration of stormy waves can be still kept, and water leakage of the pipeline is avoided effectively. Openings of a main pipeline and a slave pipeline are attached tightly by way of threaded plugging, so that the problem of water leakage can be avoided effectively. Rubber gaskets are fixed to the side walls of the opposite sides of a joining plate and a flange plate, so that the sealing effect can be further improved.
本发明公开了一种带有密封结构的船舶用管道法兰,固定法兰的一侧设立有对接法兰,对接法兰的一侧侧壁中间连接有从动管,对接法兰上连接有螺纹柱,螺纹柱螺纹连接在螺纹槽内,伸缩柱上连接有螺杆,伸缩柱内部中间设立有安装槽,螺杆位于安装槽内的一端转动连接有夹板,通过弹簧能够有效的控制伸缩柱的伸缩活动,通过螺纹柱、螺纹槽和伸缩柱,能够有效的提高连接的稳定性和密封性,使管道连接在风浪的震动中也能够保持优良的端稳定性,有效的避免管道漏水,通过螺纹插接的方式使主管道与从动管的开口紧密的贴合,能够有效的避免漏水的的问题,且在衔接板与法兰板相对的一侧侧壁上都固定有橡胶垫,能够进一步的提升密封效果。
