Scissor-Mechanism Closing Rams of Blow Out Preventors |
| 摘要 |
A ram closing assembly for a blowout preventor has a main central bore and a radial bore normal to the main central bore and includes a ram body having a rotational pin proximate to an inner end. A pair of ram arm assemblies are located on opposite sides of the ram body. The ram arm assemblies have a shaped end and an elbow end. A rotating ram is pivotally connected to the rotational pin and to the elbow end of one of the ram arm assemblies. A ram actuator is movable relative to the ram body, to move the pair of ram arm assemblies to pivot the rotating rams about the rotational pin to a closed position. |
