ASYMMETRICAL BUTTON FOR RAM-TYPE BLOWOUT PREVENTERS

摘要

An asymmetrical ram button (60) is provided. In one embodiment, a system includes a blowout preventer (10) including such a button. Particularly, the blowout preventer may include an actuation assembly having the asymmetric ram button coupled to a connecting rod (30) and a piston (28). The asymmetric body of the button can engage an internal shoulder (52) of a ram (24, 26) 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.
