Valve body detection hydraulic system and valve body detection test device

The invention discloses a valve body detection hydraulic system and a valve body detection test device, and relates to the technical field of hydraulic control. The pressurizing oil way is connected with the low-pressure cavity of the pressurizing cylinder and is used for supplying oil to the low-pressure cavity of the pressurizing cylinder; the at least one test oil path is connected with the high-pressure cavity of the pressure cylinder, so that the hydraulic oil in the high-pressure cavity with strong pressure flows into the test oil path; any test oil way is provided with a test interface used for being connected with a valve body. The control oil path is connected with the test oil path so as to control the flow direction of the hydraulic oil in the test oil path; and the emulsion oil way is connected to the high-pressure cavity of the pressure cylinder. According to the valve body detection hydraulic system, in the valve body detection process, automatic control over the flow direction and pressure of h
