Flexible graphite metal wave tooth composite gasket sealing structure

The invention discloses a flexible graphite metal wave tooth composite gasket sealing structure. The sealing structure comprises a tongue flange, a flexible graphite metal wave tooth composite gasket,a metal limiting ring and a groove flange. According to the design of the composite gasket structure, the leakage rate and the length of an internal flow channel are strictly and normatively designed, the sealing effect is greatly enhanced, connection and sealing requirements of deep low-temperature propellant pipelines and other systems can be met from quantitative control, multi-channel redundancy, temperature self-tightening and other advanced sealing requirements, and the sealing structure is suitable for connection and sealing of a rocket and missile pipeline systems. 一种柔性石墨金属波齿复合垫片密封结构，包括榫面法兰、柔性石墨金属波齿复合垫片、金属限位环、槽面法兰，通过复合垫片结构的设计，对漏率、内部流道长度进行了严格规范的设计，大大增强了密封效果，能够从定量控制、多道冗余、温度自紧等先进密封要求从发，满足深低温推进剂管路及其他系统的连接与密封要求，适用于火箭及导弹管路系统的连接与密封。
