摘要： A mechanism for locking and unlocking a reciprocating shaft includes a plate fixed to the shaft having an inclined surface. A housing surrounds the shaft and plate having a wall surrounding the inclined surface. A set of balls is located between the inclined surface and the housing wall. An assembly is translatable relative to the shaft and is biased by a spring to jam the balls between the inclined surface and the housing wall to lock the shaft against reciprocation. The assembly is movable against the force of the spring by a fluid pressure actuated cylinder to move the balls away from the inclined surface to unlock the shaft.

摘要： An isolation valve includes a housing having a port and a seal plate for sealing the port. The seal plate is linked to a shaft which carries a guide frame. To close the port, a drive mechanism drives the shaft linearly in one direction. The seal plate first moves linearly with the shaft until the guide frame stops against the housing. The seal plate then moves linearly in a direction perpendicular to a surface of the housing containing the port until it seals the port. Motion of the drive shaft in the opposite direction causes the seal plate to retrace its path. In one embodiment, the valve includes a second seal plate for sealing a second port. A spring between the guide means and the shaft provides pre-load which maintains the seal plates in a retracted position until the frame stops against the housing. An extension spring between the first and second seal plates eliminates play in the link mechanism and extends valve life.
摘要翻译： 隔离阀包括具有用于密封端口的端口和密封板的壳体。 密封板与承载引导框架的轴连接。 为了关闭端口，驱动机构沿一个方向线性驱动轴。 密封板首先与轴直线移动，直到引导框架抵住外壳。 然后密封板在垂直于包含端口的壳体的表面的方向上线性移动，直到密封端口。 驱动轴在相反方向的运动导致密封板回缩其路径。 在一个实施例中，阀包括用于密封第二端口的第二密封板。 引导装置和轴之间的弹簧提供了预加载力，其将密封板保持在缩回位置，直到框架停止在壳体上。 第一和第二密封板之间的拉伸弹簧消除了连杆机构的弹起并延长了阀门的使用寿命。
