摘要： A gate valve comprises a valve body having an internal working fluid passage and an internal gate chamber extending transverse to the working fluid passage. In addition, the gate valve comprises a gate disposed in the internal gate chamber and movable within the gate chamber between a closed position obstructing fluid flow through the working fluid passage and an open position allowing fluid flow through the working fluid passage. Further, the gate valve comprises an internal sealing arrangement coaxially disposed in the working fluid passage and extending between the valve body and the gate to form a barrier between the internal working fluid passage and the gate chamber. The internal sealing arrangement includes a frustoconical metal sealing surface adapted to sealingly engage an opposed mating frustoconical metal sealing surface on the valve body to form a first tapered metal-to-metal seal between the sealing arrangement and the valve body.

摘要： Apparatus and methods for removing valve cover components includes a torque transfer tool that mates with an extending portion of the valve cover assembly and has a multi-faceted segment to receive a torque-supplying wrench. A hydraulically-actuated wrench has a head with a multi-faceted portion that engages the corresponding multi-faceted segment of the torque transfer tool. The wrench's hydraulic cylinder rotates the wrench head upon actuation. The multifaceted segments can be splined. Also disclosed is a reaction tube against which the wrench can be braced prior to actuation of the cylinder.

摘要： A seal assembly, for sealing between a stationary conduit and a rotating conduit, comprises an upper gland assembly, a washpipe, and a lower gland assembly. The upper gland assembly is operable to engage the stationary conduit. A washpipe partially disposed within the upper gland assembly. An upper seal member is disposed within the upper gland assembly around a periphery of the washpipe. An upper packing ring is engaged with the upper gland assembly so as to compress the upper seal member into sealing engagement with the washpipe. A lower gland assembly is disposed about the washpipe and operable to engage the rotating conduit. A lower seal member is disposed within the lower gland assembly and is compressed into sealing engagement with the washpipe by a lower packing ring that is engaged with the lower gland assembly. The engagement of the packing rings with their respective gland assemblies is independent of the engagement of the gland assemblies and the conduits.
