    • A stopcock is provided with multipleports joining multiplefluid conduits leading between fluid sources and fluid destinations. A central hub manifold resides within a valve body supporting the ports, and can rotate relative to the valve body. Fluid flow paths within the central hub are selectivelyaligned or not aligned with the ports. The stopcock indicates which ports are open by providing marks corresponding with positions of the ports. When the marks are visible, the corresponding ports are open. With different positioning of ports and different configurations of fluid flow paths within the central hub, stopcocks having different numbers of operable positions are provided including two, three, four, six and eight way stopcocks. By providing an axial flow path through a central axis of the central hub intersecting the embedded fluid flow paths within the central hub, still further numbers of operational states are provided.
    • 一个旋塞阀设有多个通道,连接流体源和流体目的地之间的多个流体管道。 中央集线器歧管位于支撑端口的阀体内,并且可相对于阀体旋转。 中央轮毂内的流体流动路径可选择性地对齐或不与端口对齐。 通过提供与端口位置相对应的标记,活栓指示哪些端口打开。 当标记可见时,相应的端口是打开的。 随着端口的不同定位和中心毂内流体流动路径的不同配置,提供具有不同数量的可操作位置的活栓,包括2,3,4,6和8路活塞。 通过提供穿过中央轮毂的中心轴线的轴向流动路径与中央轮毂内的嵌入式流体流动路径相交,提供了更多数量的操作状态。
