Title:
DEVICE FOR TESTING STEAM TURBINE VALVE CHARACTERISTICS
Document Type and Number:
WIPO Patent Application WO/2024/046500
Kind Code:
A1
Abstract:
A device for testing steam turbine valve characteristics, comprising a case, wherein a control card (1), an acquisition card (2) connected to the control card (1), an acquisition interface (3) connected to the acquisition card (2) and a pressure sensor in a hydraulic servomotor, and an industrial personal computer (4) connected to the control card (1) and the acquisition card (2) are provided in the case. According to the device, a worker can comprehensively and intuitively monitor the operation of a proportional valve and perform fault diagnosis, so that a fault can be predicted in advance, and a fault handling person is prompted to take a corresponding measure, and during maintenance of a control system for a steam turbine valve, the control system can be replaced with the device to control the proportional valve, so that the reliability of a steam turbine valve system is improved.
