摘要： A tubing retrievable surface controlled subsurface safety valve having a rotatable ball-type flow closure element is disclosed. The ball element is rotationally operated and guided by a pair of guide members fixed in the valve by a stop ring. The guide members co-act with the ball to provide the desired rotational movement as well as providing a movement limit stop to prevent rotational overtravel of the ball. The tubular operator means imparts longitudinal movement to the ball greater than the predetermined movement required to effect the desired ball rotation prior to engaging the stop ring.A locking sleeve having a longitudinal locking movement greater than the predetermined movement to rotate the ball open is provided. Operating movement of the locking sleeve uncovers a control fluid port for operating a supplemental subsurface valve operably secured with the valve. Prior to activating the locking sleeve to install the supplemental valve, the valve may be controlled through either of two conduits. Only one conduit may be used to operate the supplemental valve.

摘要： A sliding sleeve valve for downhole use. A tubular main body has a radial flow port there-through and a primary annular seal carried adjacent its inner diameter and spaced longitudinally from the flow port in a first direction. A sleeve is carried co-axially within the main body for selective relative longitudinal movement. The sleeve has a seal section with an outer diameter sized to slidably sealingly engage the primary seal. The sleeve also has a radial aperture through the seal section and a recess in the outer surface of the seal section, surrounding and longer than the radially outer end of the aperture. The sleeve has a closed position, wherein the aperture and recess are longitudinally spaced from the primary seal in the first direction, and an open position, wherein the aperture is longitudinally spaced from the primary seal in a second direction opposite the first. The recess is sized and configured to permit the aperture to pass the primary seal while moving from closed to open position, under given temperature and pressure conditions, without substantial damage to the primary seal.
摘要翻译：用于井下使用的滑动套管阀。管状主体在其上具有径向流动端口，并且邻近其内径承载并沿着第一方向与流动端口纵向间隔开的主环形密封件。套筒在主体内同轴地承载，用于选择性的相对纵向移动。套筒具有密封部分，其外径的尺寸可滑动地密封地接合主密封件。套筒还具有穿过密封部分的径向孔和在密封部分的外表面中的凹部，围绕并且比孔的径向外端长。套筒具有闭合位置，其中孔和凹部在第一方向上与主密封件纵向间隔开，并且打开位置，其中孔与主密封件在与第一方向相反的第二方向纵向间隔开。凹槽的尺寸和构造允许孔在给定的温度和压力条件下从闭合到打开位置移动通过主密封，而不会对主密封件造成实质损坏。

摘要翻译：公开了一种具有可旋转的球形流动闭合元件的可回收的表面控制的地下安全阀。滚珠元件由一对通过止动环固定在阀中的引导构件旋转地操作和引导。引导构件与球共同作用以提供期望的旋转运动，以及提供移动限制挡块以防止球的旋转超程。管状操作器装置将大于在接合止动环之前实现所需球旋转所需的预定运动的球的纵向运动。提供了一种锁定套筒，其具有大于预定运动的纵向锁定运动以旋转球打开。锁定套筒的操作运动揭开一个控制流体端口，用于操作与阀可操作地固定的辅助地下阀。在启动锁定套筒以安装补充阀之前，阀可以通过两个管道中的任一个来控制。只能使用一个导管来操作补充阀。
