摘要： An equalizing subsurface safety valve for controlling fluid flow in a well conduit comprises a tubular body member having a longitudinal bore extending therethrough, a flapper hingably connected within the tubular body member to alternately permit and prevent fluid flow through the longitudinal bore, means for biasing the flapper to a normally closed position to prevent fluid flow through the longitudinal bore, a flow tube longitudinally movable within the longitudinal bore for controllably opening the flapper, fluid passage formed within the tubular body for providing fluid communication between the longitudinal bore adjacent a first side of the flapper and a second side of the flapper, and a closure member mounted across the fluid passage adjacent the first side of the flapper and movable along an axis generally transverse to the longitudinal bore. A side wall of the flow tube includes a first notch so that the closure member is maintained in a closed position when the flow tube is in a retracted position and the closure member is moved to an open position when the flow tube is moved to open the flapper. A second notch can be included in the flow tube so that the closure member will return to a closed position when the flow tube is extended to a position where the flapper is opened.
