The pipeline structure comprises a main pipeline, a connecting flange, a valve connecting flange, a large valve and a sealing middle flange, the main pipeline penetrates through cabins and watertight plates between the cabins, and the connecting flange, the large valve and the sealing middle flange are arranged on the main pipeline. The sealing middle flange is arranged at the position where the main pipeline is connected with the watertight plate, a large valve is arranged on the pipe section between the connecting flange and the sealing middle flange, valve connecting flanges are arranged at the two ends of the large valve, and the connecting flanges are obliquely arranged flanges. The connecting flange adopts the bevel flange for connection and disassembly, so that the disassembly is more convenient, and a disassembly pipeline and a large valve cannot be damaged. The connecting flanges are connected in an oblique angle mode, at the moment, when the valve is disassembled, the disassembling flange can bear vertically-upward force, the disassembling flange can be easily disassembled by being matched with a chain block hung on a lifting lug, and the problem that a large valve is difficult to disassemble is solved.

    本发明涉及一种便于船舶压载舱阀门拆卸的管路结构,包括:主管路、连接法兰、阀门连接法兰、大阀门和密封中法兰,所述主管路穿过舱室及各舱室之间的水密板,所述主管路上设置有连接法兰、大阀门和密封中法兰,所述密封中法兰设置于主管路与水密板连接的位置,所述连接法兰和密封中法兰之间的管段上设置大阀门,大阀门的两端设置有阀门连接法兰,所述连接法兰为倾斜设置的法兰。本发明连接法兰采用斜角法兰连接拆卸时更加方便,不会对拆卸管路与大阀门造成损坏。连接法兰采用斜角连接,此时拆卸阀门时,拆卸法兰会承受一个竖直向上的力,再配合悬挂在吊耳上的手拉葫芦可以轻松的将拆卸法兰拆卸下来,解决大阀门拆卸困难的问题。
