摘要： A wellhead seal assembly forms a metal-to-metal seal between inner and outer wellhead members. A metal seal ring has inner and outer walls separated by a slot. A lock ring has grooves for locking the inner wellhead member to the outer wellhead member during installation. An energizing ring has a C-ring captured on its inner surface. When the energizing ring is moved further into the slot, the C-ring is forced from its pocket and engages the surface of the inner wellhead member, locking the seal assembly to the inner wellhead member.

摘要翻译： 井口密封组件在内部和外部井口构件之间形成金属对金属密封。 金属密封环具有由槽分隔的内壁和外壁。 锁定环具有用于在安装期间将内部井口构件锁定到外部井口构件的凹槽。 激励环在其内表面上具有C形环。 当激励环进一步移动到槽中时，C形环从其凹口被迫动并与内部井口构件的表面接合，将密封组件锁定到内部井口构件。
