Beschreibung
Zusammenfassung:	A measuring device and a testing method for action performance analysis of a main steam release isolating valve under a long opening condition belong to the technical field of valve testing and comprise a gas supply device, a pipeline transmission system, a pipeline high-temperature gas flow monitoring device, a pressure monitoring system, a main steam release isolating valve system, a valve rod displacement monitoring device and a data acquisition system. The pressure monitoring system comprises a upstream pressure monitoring device and a downstream pressure monitoring device. The gas supply device is communicated with the pipeline transmission system, the pipeline high-temperature steam gas flow monitoring device and the pressure monitoring system are arranged on the pipeline transmission system, the main steam release isolation system is connected with the pipeline transmission system, and the valve rod displacement monitoring device is arranged at the top of the main steam release isolation system. And th
