方法兰密封设计研究

The Research of Square Flange Tight Design

船舶上的液压系统通过封闭回路中的受压流体来传递和控制功率,起着举足轻重的作用。系统中的各个元件、附件和管路均需密封,其中液压管路密封的好坏取决于管子连接。液压管连接形式主要为方法兰连接,O形圈和沟槽的选取合理与否直接影响到液压方法兰密封性能的好与坏。

Marine hydraulic system is important as it transmits and controls the power through the pressure fluid in closed circuit. The elements, attachments and pipe fittings in the systems are all needed to be sealed. The sealing of hydraulic pipeline depends on pipe connection. Square flange connection is the primary connection type in hydraulic pipeline connections. The selection of O-rings and grooves directly affect the sealing of hydraulic square flange.
