Automatic monitoring of valve status (June 1989).

摘要

Authors propose establishing the relationship between valve leaking and thermal gradient to allow detection of valve leakage by observing the piping system's temperature profile and using an expert system to infer the valve condition. They describe their work toward this and their January 1988 report thereon. The authors also suggest designing modem power plants to accommodate a remotely controlled or autonomous vehicle which would carry a device for thermal-gradient leak detection to examine valves in situ.
