An automatic testing system for a hydraulic check valve, including a factory testing terminal, a customer testing terminal, and a processing background; wherein, the factory testing terminal includes a liquid oil injection device, and the liquid oil injection device is connected to one end of the first oil pipe, and the other end of the first oil pipe One end is connected to a one-way valve detection area, the one-way valve detection area is connected to one end of the second oil pipe, the other end of the second oil pipe is also provided with a first valve, and the second oil pipe between the one-way valve detection area and the first valve Partially provided with a first pressure sensor. The beneficial effect of the present invention is: after passing the detection of the factory inspection end, label each qualified one-way valve, and correspond the one-way valve with the label one by one, so as to prevent customers from causing losses due to abnormal one-way valves, and change the traditional The problem of damage to the one-way valve is realized only when there is leakage in the method; at the same time, by recording the time point during installation and the time point when it is abnormal, it can be analyzed to obtain the different life spans of the one-way valve under different hydraulic environments, which is convenient for customers according to actual needs. choose.
