    摘要： A valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, wherein the inlet and outlet passageways fluidly communicate with the internal region. A valve seat is positioned within the internal region defining a fluid passageway. A hanger is connected to the valve body. A linkage assembly is pivotally and rotatably to the hanger and a valve member is pivotally connected to the hanger via the linkage assembly, wherein the valve member is movable between an open configuration, in which fluid flow is permitted through the fluid passageway, and a closed configuration, in which the valve member engages the valve seat to at least partially restrict fluid flow through the fluid passageway.

    摘要： A subsurface safety valve assembly that includes a valve housing comprising a valve seat with a circumference and a seat seal surface. The valve assembly also includes a flapper rotatably connected to the valve housing and comprising a flapper seal surface. The flapper is rotatable into sealing engagement with the seat seal surface in a closed position to form a circumferential surface-to-surface seal. The valve assembly also includes a dovetail groove cut into the seat seal surface or the flapper seal surface and a seal ring held within the dovetail groove and positioned to form a seal against the seal ring when the flapper is in the closed position. The seat seal surface, the flapper seal surface, the dovetail groove, and the seal ring are shaped such that the load on the seal ring is uniform around the seal ring when the flapper is in the closed position.

    摘要： One or more techniques and/or systems are disclosed for a flap valve in a diaphragm pump. The flap valve includes a body and a self-centering hinge portion. A front portion of the body includes a front surface having a raised portion and a recessed portion. The front surface is configured to form a seal with a surface of the pump when the body is in a closed position, the surface of the pump being at an inlet or an outlet of a pumping chamber. The body is configured to allow a downstream flow of a fluid when the flap valve is in an open position. The self-centering hinge portion is operably connected to the body. The self-centering hinge portion has a dynamically changing longitudinal axis. The body is configured to simultaneously translate and rotate about the dynamically changing longitudinal axis to form the seal.
