摘要： A control system for a subsurface safety valve addresses normal open and closed operation and a failsafe operation if key system components fail. It features a single control line (20) from the surface that splits at the subsurface safety valve and goes to one end of two discrete piston chambers (64, 46) that are aligned and isolated from tubing pressure. The piston (36) in one chamber is larger than in the other and the pistons (36, 52) are connected for tandem movement. Each side of the unbalanced system's piston has a seal mounted to it (38, 54) and another for the rod (40, 56) attached to it that exits the chamber. A jumper line (68) connects the chambers (48,62) at a point between the seals in each chamber and features a large reservoir (70). The jumper line (68) is filled with a compressible fluid. Fail safe closure of the valve occurs if any of the four seals fail.
摘要翻译：用于地下安全阀的控制系统解决了正常的开启和关闭操作以及关键系统组件故障时的故障安全操作。它具有来自表面的单个控制线（20），其在地下安全阀处分开并且进入与管道压力对准和隔离的两个离散活塞室（64,46）的一端。一个室中的活塞（36）大于另一个室中的活塞（36），并且活塞（36,52）连接用于串联运动。不平衡系统的活塞的每侧具有安装到其上的密封件（38,54），另一个用于连接到其上的杆（40,56），该杆连接到室。跨接线（68）在每个室中的密封件之间的点处连接腔室（48,62），并且具有大的储存器（70）。跳线（68）填充有可压缩流体。如果四个密封件中的任何一个发生故障，则会发生阀门的故障安全关闭。

摘要： A control system can be used with a single control line (10) to a subsurface safety valve. The operating piston ( 16 ) is exposed to the flow tube (32 ) between two blocks with near identical seals (42, 26) to make the piston insensitive to tubing pressure. A control system seal (18) is carried by the piston in the upper block and a passage (4 ) between the control system seal and the tubing pressure seal in the upper block communicates to a compressible fluid reservoir (38 ) in the lower block that is also isolated from tubing pressure by a tubing pressure seal. Movement of the piston compresses the fluid in the reservoir. The reservoir can also include a spring (52 ) to return the piston and the flow tube to a position to close the valve. A redundant system ( 56 ) can be actuated if the primary system fails.
摘要翻译：控制系统可以与单个控制线（10）一起用于地下安全阀。操作活塞（16）在具有近似相同的密封件（42,26）的两个块之间暴露于流动管（32），以使活塞对管道压力不敏感。控制系统密封件（18）由上部块中的活塞承载，并且控制系统密封件和上部块体中的管道压力密封件之间的通道（4）与下部块体中的可压缩流体储存器（38）连通，也通过管道压力密封与管道压力隔离。活塞的运动压缩储存器中的流体。储存器还可以包括弹簧（52），以将活塞和流管返回到关闭阀的位置。如果主系统发生故障，则可以启动冗余系统（56）。

摘要： Systems for operating one or more sliding sleeve valves in an incremental, step-type fashion between open and closed positions, permitting the valve or valves to be choked to progressively smaller flow areas. The systems of the present invention also permit the valve or valves to be fully closed without having to progress through incremental steps.

摘要： A backup stem seal for a gate valve retains pressure in the body when the valve is in the closed position. The backup seal is secondary to the main stem seal assembly (20) in the bonnet (12). It features metal-to-metal contact between surfaces (22, 24) that are radially oriented or sloping and further can contain a retaining groove (26) for a seal ring (32) in one or both the opposed metal-to-metal surfaces (22, 24). The groove (26) can be formed to better retain the ring (32) from damage from flowing fluids when the valve is open. A passage through the bonnet (34) may be used to test for leakage past such seal. The backup seal allows maintenance of the main stem seal (20) without removing the valve from service.
