摘要： A valve has a valve member (17) that is moveable along a first axis in a valve chamber ( ) between an open position and a closed position. In the open position the valve member is displaced from the valve seat such that a fluid inlet (pi) is connected to a fluid outlet (p2). In the closed position the valve member (17) is sealed against the valve seat so that the fluid path is closed. First (12) and second (46) opposed stacks of disc spring apply unequal loading resulting in a biasing force that biases the valve member towards the closed position. A first piston member (15) is movable in a first bore (14) relative to the valve member (17) and for moving the valve member in a first direction along the first axis. A second piston member (16) is movable in a second bore relative to the valve member (17) for moving the valve member along the first axis in a second direction opposite to the first direction. A first pressure compensation passage (71) extends between the fluid inlet (pi) and the first bore (14) such that the first piston member (15) is actuable by the fluid pressure in the fluid inlet (pi). A second pressure compensation passage (70) extends between the fluid outlet (p2) and the second bore such that the second piston member (16) is actuable by the fluid pressure in the fluid outlet. An actuator moves the valve member from the closed position to the open position.
摘要翻译：阀具有阀构件（17），该阀构件可在阀室（）中在打开位置和关闭位置之间沿着第一轴线移动。在打开位置，阀构件从阀座移位，使得流体入口（pi）连接到流体出口（p2）。在关闭位置，阀构件（17）被密封抵靠阀座，使得流体路径关闭。第一（12）和第二（46）相对的盘形弹簧堆叠施加不相等的加载，导致偏压力使阀构件偏向关闭位置。第一活塞构件（15）可相对于阀构件（17）在第一孔（14）中移动，并且沿着第一轴沿第一方向移动阀构件。第二活塞构件（16）可相对于阀构件（17）在第二孔中移动，用于沿与第一方向相反的第二方向沿着第一轴线移动阀构件。第一压力补偿通道（71）在流体入口（pi）和第一孔（14）之间延伸，使得第一活塞构件（15）可通过流体入口（pi）中的流体压力致动。第二压力补偿通道（70）在流体出口（p2）和第二孔之间延伸，使得第二活塞构件（16）可通过流体出口中的流体压力致动。执行器将阀构件从关闭位置移动到打开位置。

摘要： A hydraulic coupling for sub sea applications comprises inter-engageable male and female connectors. The male connector defines a male member for receipt in a chamber defined by the female connector. Each connector has a respective check valve for controlling the flow of fluid through internal bores in the connectors. The check valves are actuable by an actuator between an open position in which hydraulic fluid may flow through the respective internal bore and a closed position in which such flow is interrupted, depending on the distance between the first and second check valves. The male and female connectors are moveable between an uncoupled position in which the check valves are in the closed position and a coupled position in which the male and female connectors are engaged and extend along a longitudinal axis with the male member occupying the chamber of the female connector in a sealed relationship. A pair of seals are provided one on the male member and the other on the in the chamber. The seals are arranged so that they seal the chamber at opposite ends by sealing against respective sealing surfaces in the coupled position. The distance between the first and second check valves in the sealing position is such that the actuator urges them to their open positions. The arrangement ensures that seawater between the connectors is allowed to escape before the sealing relationship is established and, upon coupling, the check valves are opened to allow fluid to flow.
摘要翻译：用于海底应用的液压联轴节包括可互接的公和母连接器。阳连接器限定用于容纳在由母连接器限定的室中的阳构件。每个连接器具有相应的止回阀，用于控制流体通过连接器中的内孔流动。取决于第一和第二止回阀之间的距离，止回阀可由致动器致动，打开位置之间的液压流体可以流过相应的内孔，并且闭合位置中，这种流动被中断。公连接器和阴连接器可在其中止回阀处于关闭位置的非耦合位置和连接位置之间移动，在该联接位置，阳和阴连接器接合并沿着纵向轴线延伸，阳构件占据阴室的室连接器密封的关系。一对密封件设置在阳构件上，另一个在腔室中。密封件被布置成使得它们在相对的端部通过密封在联接位置中的相应密封表面来密封腔室。在密封位置中的第一和第二止回阀之间的距离使得致动器将它们推到它们的打开位置。这种布置确保了连接器之间的海水在建立密封关系之前允许逃逸，并且在联接时，打开止回阀以允许流体流动。
