    摘要： An isolation valve includes a dead chamber, including a body with a fluid-passing conduit, a device for obturating the fluid passage in the conduit, which may be actuated between a fluid-passing position and a position for obturating the fluid passage in the conduit. In its obturation position, the obturation device forms a dead chamber. A wall of the obturation device comprises a through-hole, in which is positioned a device for decompression of the dead chamber. A hydrocarbon transport facility includes at least two pipes connected through such an isolation valve with a dead chamber.

    摘要： A safety valve releases a fluid in the event of a fire. To do so it comprises a valve shutter in a body for opening or closing a pipe containing the fluid. A first spring is kept under tension against heat-sensitive means for releasing the valve shutter ROM when the tension is released by the sensitive means. The sensitive means comprise a piston acting on the first spring, a pipe being connected to a chamber delimited in the body ROOM by the piston on the opposite side to the first spring. The pipe and the chamber contain a pressurized control fluid so that the piston keeps the first spring under tension. The pipe is made of a material capable of melting at a predetermined temperature so as to release the fluid in the event of a fire around the pipe.

    摘要： A shuttle valve assembly for an hydraulically actuated tool has a primary chamber with a primary inlet port located at an upstream end thereof for communicating with an hydraulic fluid supply. The primary inlet port defines an inlet valve seat with an inlet stop located downstream. An inlet valve member is displaceable along an inlet valve path between a closed position sealingly engaging the inlet valve seat to at least substantially prevent flow of hydraulic fluid through the primary inlet port and an open position engaging the inlet stop and allowing flow. A primary outlet port is located at a downstream end of the primary chamber for communicating the primary chamber with an actuable member of the tool. The primary outlet port defines an outlet valve seat with an outlet stop located downstream.

    摘要翻译： 用于液压致动工具的梭阀组件具有主室，其具有位于其上游端的主入口端口，用于与液压流体供应源连通。 主入口端口限定了入口阀座，其中位于下游的入口止动件。 入口阀构件可沿密封地接合入口阀座的关闭位置之间的入口阀路径移位，以至少基本上防止液压流体通过主入口端的流动，以及接合入口止动件并允许流动的打开位置。 主出口位于主室的下游端，用于将主室与工具的致动构件连通。 主出口端口限定出口阀座，出口止动件位于下游。
