Abstract: A valve includes a body having upstream and downstream ports, both ports configured relative to a common axis, and includes a ball arranged to rotate relative to the common axis between open and closed positions to allow for fluid flow/non-fluid flow. The ball has a calibrated member having a calibrated orifice that has a flow coefficient, pressure taps located upstream and downstream of the calibrated orifice and in communication with the upstream and downstream ports respectively to measure upstream and downstream pressures when in the open position, the upstream and downstream pressure taps are angled relative to the common axis, so conditions of fluid flow are determined based on a measured pressure differential between upstream and downstream pressure taps relative to the flow coefficient of the calibrated orifice when in the open position.

Abstract translation: 阀包括具有上游和下游端口的主体，两个端口相对于公共轴线构造，并且包括布置成相对于公共轴线在打开位置和闭合位置之间旋转以允许流体流动/非流体流动的球体。 球具有校准构件，其具有校准孔口，该校准孔口具有流量系数，位于校准孔口的上游和下游的压力抽头，并分别与上游端口和下游端口连通，以在打开位置时测量上游和下游压力，上游 并且下游压力抽头相对于公共轴线成一定角度，因此基于当在打开位置时相对于校准孔口的流动系数测量的上游和下游压力抽头之间的压力差来确定流体流动的条件。
