    • A liveload assembly having a stack guide with a thread on the exterior side wall, a plurality of compressible belleville washers stacked inside the stack guide, and a retainer cap having a thread on an inner side wall for matingly engaging with the stack guide to hold the belleville washers in compression. The gland follower of a fluid flow apparatus is liveloaded by placing the liveload assembly over the bolt extending upwardly from the gland follower. A nut is threaded on the bolt to contact the stack of belleville washers and the retainer cap is unscrewed to a second position on the stack guide and fixed by turning a set screw through a bore in the cap and against the side of the stack guide. Compression of the gland follower is monitored by viewing the relative movement of the stack of belleville washers through a longitudinal slot in the side wall.
    • 一种具有在外侧壁上具有螺纹的堆叠引导件的堆叠引导件,堆叠引导件内部的多个可压缩的贝尔垫圈,以及在内侧壁上具有螺纹的保持器盖,用于与堆叠引导件配合地接合以保持 贝尔维尔洗衣机在压缩。 流体流动装置的压盖随动件通过将活载组件放置在从压盖随动件向上延伸的螺栓上而被活动。 螺母上的螺母被螺纹连接在一起,以接触一叠贝氏垫圈,并将保持器帽旋拧到堆叠引导件上的第二位置,并通过转动固定螺钉穿过盖中的孔并抵靠堆叠导向器的一侧来固定。 通过观察通过侧壁中的纵向狭槽的百叶窗垫圈的相对运动来监测压盖随动体的压缩。
