    摘要: A valve assembly includes a valve body and an opening extending through the valve body along a longitudinal axis. The valve assembly also includes a valve member arranged within the opening, the valve member being movable, along the longitudinal axis, between an open position and a closed position. The valve assembly includes an upper seal positioned to seal against at least a first portion of the valve body. The valve assembly includes a lower seal positioned to seal against at least a second portion of the valve body, wherein both the upper seal and the lower seal travel with the valve member as the valve member moves between the open position and a closed position.

    摘要: A valve assembly includes a valve body and a valve member extending through at least a portion of the valve body. The valve assembly also includes a seat pocket forming an annular recess in the valve body and a seat arrangement positioned at least partially within the seat pocket. The seat arrangement includes a lower seat extending radially inward from the annular recess toward the valve cavity axis. The seat arrangement also includes an upper seat at least partially overlapping the lower seat, the upper seat extending radially inward toward the valve cavity axis to contact the valve member along a seat face. The seat arrangement further includes an interface seal positioned along an interface between the upper seat and the lower seat, the interface seal receiving a fluid pressure to drive the lower seat radially outward and into the annular recess.

    摘要: A valve seal assembly that provides for external pressure to be introduced to an energized seal of a valve, and compress the seal against a gate with enough force to block any paths where sand and chemicals would otherwise travel into valve body cavity or void. The external pressure introduced through pressure fitting makes the parts move like piston forcing the parts to compress together eliminating the machined tolerances or gaps required for the gate to be opened or closed. The compression can be provided by hydraulic pressure devices through injection ports. A separate valve seal assembly can be provided for each face of the gate and both assemblies can be activated when the fluids are flowing (open position) and an upstream valve seal assembly activated when the gate is in a closed position.

    摘要: Improved apparatuses, systems, and methods for sealing a frac valve using pressurized fluid to drive one or more seal assemblies into sealing contact with a valve gate without substantial relative movement of the seal assembly components. In some embodiments, the improved apparatuses, systems, and methods provide a sealant to the face of the valve gate to ensure a fluid tight seal, a plurality of biased springs to ensure the seal assemblies are positioned properly to create a fluid tight seal, a shield to prevent fluids, particulates, and/or other materials from interfering with the operation of or damaging the seal assemblies, and/or a recess for receiving fluids, particulates, and/or other materials that would otherwise interfere with a fluid-tight seal or cause damage to the seal assemblies or valve gate.
