摘要： A method to detect cycling of components that result from use of a tight shut-off mode on a valve assembly. Embodiments of the method use operating data from the valve assembly. This operating data includes data that reflects a position for the closure member relative to the seat. This position often corresponds with a measured position of one or more components (e.g., the valve stem) on the valve assembly. In one embodiment, the method includes steps for comparing the measured position to a boundary criteria that defines one or more boundary values proximate, and often equal to, the threshold levels of the tight shut-off mode. The method can also includes steps for identifying patterns in the data that indicate that the closure member is cycling from its closed position to a second position due to tight shut-off mode.

摘要： Embodiments of a system that can detect leaks that occur in seals, and in one example, to seals found in a valve. In one embodiment, the system utilizes sensors that measure fluid properties of a sample volume proximate to the seal. The system can compare data from these measurements with data from a sample of a reference fluid (e.g., ambient air) to indicate the presence of working fluid in the sample volume. This result may indicate problems with the seal, e.g., degradation of the seal that is meant to prohibit the working fluid from migrating out of the valve.
摘要翻译：可以检测在密封件中发生的泄漏的系统的实施例，并且在一个示例中可以检测在阀中发现的密封件的泄漏。在一个实施例中，系统利用测量靠近密封件的样品体积的流体特性的传感器。系统可以将来自这些测量的数据与来自参考流体（例如，环境空气）的样品的数据进行比较，以指示样品体积中存在工作流体。该结果可能指示密封件的问题，例如意图是阻止工作流体从阀门移出的密封件的劣化。

摘要： A system that provides localized monitoring of characteristics of instrument gas that a valve assembly (104) uses to modulate the flow of a working fluid (112). The system includes components (102) that generate an output in response to, for example, particulates, humidity, temperature, and other characteristics of the instrument gas. Processing of data and information in the output can help to diagnose changes in the characteristics of the instrument gas. This diagnosis is useful to predict a time frame during which the valve assembly and components associated therewith might fail and/or require maintenance before the valve assembly manifests significant problem that are detrimental to a process line.
