Description

Technical Field

[0001] The utility model relates to the technical field of hydropower station maintenance, in particular to a hydraulic integrated valve block detection platform. Background Art

[0002] The hydraulic system of a hydropower station's rapid gates is crucial for opening and closing the gates. According to equipment maintenance standards, the hydraulic system must be overhauled every few years, with a particular emphasis on the integrated valve block. Throughout the hydraulic system, the solenoid valves on the integrated valve block must function correctly to open and close the gates. Furthermore, the internal leakage of the integrated valve block directly affects how often the gates slide when the cylinder is holding the gate. Generally, the greater the internal leakage, the more frequent the gates slide. If the gates continue to slide, they can directly cut off the water inlet, causing major accidents such as unit shutdowns. Therefore, testing the integrated valve block before and after repair is essential. Currently, however, there is no standardized testing platform for testing integrated valve blocks.
