Zusammenfassung:The invention discloses a test bed for detecting the performance of a hydraulic valve under high and low temperature conditions, belongs to the technical field of hydraulic valve detection, and aims to solve the problem that a traditional hydraulic test bed can only detect the pressure and flow of the hydraulic valve and cannot detect the working characteristics of the hydraulic valve under the high and low temperature conditions. The test bed comprises a supporting table body, a vertical partition plate, an oil tank, a visual glass cover, a gas tank, a horizontal partition plate, an oil liquid temperature adjusting unit, a hydraulic valve performance detection unit and an environment temperature adjusting unit, and the oil liquid temperature adjusting unit comprises a second oil well pump, a hydraulic oil cooler, a first temperature sensor and a first electromagnetic reversing valve. The environment temperature adjusting unit comprises a test temperature adjusting subunit and a gas tank temperature self-adju
