摘要： An asymmetrical ram button is provided. In one embodiment, a system includes a blowout preventer including such a button. Particularly, the blowout preventer may include an actuation assembly having the asymmetric ram button attached to a connecting rod coupled to a piston. The asymmetric body of the button can engage an internal shoulder of the ram such that a retraction force on the actuation assembly causes the asymmetrical ram button to load against the internal shoulder. Additional systems, devices, and methods are also disclosed.

摘要翻译： 提供非对称的拉杆按钮。 在一个实施例中，系统包括包括这种按钮的防喷器。 特别地，防喷器可以包括具有附接到联接到活塞的连杆的非对称柱塞按钮的致动组件。 按钮的不对称主体可以接合柱塞的内部肩部，使得致动组件上的缩回力使不对称的压头按钮抵靠在内部肩部上。 还公开了附加的系统，装置和方法。
