摘要：NOVELTY - The device has a test bench including a direct current (DC) boiler (1), a steam-water separator (2), an energy storage container (3) and a safety valve test container (4). A bottom part of the test container is provided with four valves (17-20). A large-caliber adjusting valve (7) is connected with a small diameter valve (8) in a parallel manner. A safety valve (12) is connected with an isolation valve (10) that is connected with a small-caliber ball valve (11). A device main body is provided with a quantity simulating piece. Scanning period of the quantity simulating piece is less than 10 ms. USE - Safety valve state machinery property testing device. ADVANTAGE - The device has high processing precision, strong safety performance and high automation degree, and effectively realizes safety valve frequency hopping process and safety valve state machinery property testing process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a safety valve state machinery property testing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a safety valve state machinery property testing device.
