摘要： A gate valve seat for a gate valve includes a seat having a stepped outer wall surface, with a spring, spacer ring, front facing lip seal, and a rear facing lip seal disposed about the stepped outer surface of the seat. The spring may be releasably locked into a compressed configuration for installation of the gate of the gate valve.

摘要： A slurry gate valve incorporating dual gates for the positive interruption of fluid flow through a pipeline associated with the valve. The dual gate valve is movable through three positions: a fully open position, a half open position, and a full closed position. The valve includes a main leader gate and a follower gate each having selectively alignable fluid passageways. An interlock mechanism selectively connects the dual gates for simultaneous travel once the gates have reached the half open position. The dual action gate valve reduces wear on the downstream resilient seals associated with the valve by shielding the seal against the fluid flow through the main passageway of the valve.
摘要翻译：一种浆料闸阀，包括双门，用于通过与阀相关联的管道的流体流动的中断。双闸阀可以通过三个位置移动：完全打开位置，半打开位置和完全关闭位置。阀包括主导向门和随动门，每个门都具有可选择性地对准的流体通道。一旦门已经达到半打开位置，互锁机构选择性地连接双门同时行进。双作用闸阀通过屏蔽密封件抵抗通过阀的主通道的流体流动来减少与阀相关联的下游弹性密封件的磨损。

摘要： A blowout preventer and a seal are disclosed for sealing about pipes or other objects in a well bore. The seal element is a semi-circular section of resilient compressible material having a semi-circular inner surface to engage the pipe and embedded radially disposed support elements having anti-extrusion members which serve in combination with overlapping ram block members to prevent extrusion of the resilient material from the top and bottom of the seal. The top and bottom anti-extrusion members are stair stepped and have interlocking fingers and recesses and are adapted to slide radially and circumferentially with an adjacent anti-extrusion member element as the elements move toward or away from the pipe in the well bore. Flanges on the seal element are provided with top and bottom plates each of which overlaps at least one support element.
