摘要： A pressure isolation device for a pipeline system is described. The pressure isolation device changes from an open position to a closed position when the pressure of a fluid flowing through the device exceeds a predetermined threshold pressure. In some embodiments, the pressure isolation device comprises a housing having an internal chamber, a main inlet, and a main outlet. An elongated member is disposed within the internal chamber between the main inlet and main outlet, and is biased towards the open position. As fluid pressure increases, the elongated member is pushed to the closed position and a portion of the elongated member blocks the fluid pathway from the main inlet to the main outlet. The pressure isolation device provides a simple mechanical solution to protecting and isolating downstream pipeline components from over-pressurization.
摘要翻译：描述了用于管道系统的压力隔离装置。当流过该装置的流体的压力超过预定阈值压力时，压力隔离装置从打开位置改变到关闭位置。在一些实施例中，压力隔离装置包括具有内部室，主入口和主出口的壳体。细长构件设置在主入口和主出口之间的内室内，并朝向打开位置偏置。当流体压力增加时，细长构件被推动到关闭位置，并且细长构件的一部分阻挡从主入口到主出口的流体路径。压力隔离装置提供了一种简单的机械解决方案，用于保护和隔离下游管道部件免于过压。

摘要： A pressure isolation device for a pipeline system is described. The pressure isolation device changes from an open position to a closed position when the pressure of a fluid flowing through the device exceeds a predetermined threshold pressure. In some embodiments, the predetermined threshold pressure is defined, in part, by a spring. The pressure isolation device provides a simple mechanical solution to protecting pipeline components from over-pressurization.
