Abstract: A sampling device uses two ball valves that may be operated to take a sample while allowing flow to continue in a bypass path in a pressurized pipe. As one ball valve closes, it may capture a sample of liquid and gas that may be traveling in the pipe, then the sample may be discharged through a sampling outlet. The second ball valve may be operated simultaneously to open a bypass path while the first ball valve captures a sample. In some cases, the speed of actuation may be a function of the flow speed to capture an accurate sample. In other cases, the length of pipe from the sampling valve to the bypass junction may determine the effectiveness of the sample when actuation speed is relatively slow.

Abstract translation: 采样装置使用两个球阀，其可以被操作以取样，同时允许在加压管道中的旁路通路中继续流动。 当一个球阀关闭时，它可以捕获可能在管道中行进的液体和气体样品，然后样品可以通过取样出口排出。 当第一球阀捕获样品时，第二球阀可以同时操作以打开旁路路径。 在某些情况下，致动速度可能是捕获准确样品的流速的函数。 在其他情况下，从采样阀到旁路接头的管道长度可以确定当启动速度相对较慢时样品的有效性。
