[0002] Solenoid directional valve is one of the most widely used hydraulic components in the hydraulic system, so the output of general manufacturers is very large. The electromagnetic directional valve with the same diameter has more than a dozen functions, and the electromagnetic directional valve of each function The sampling test standard of the electromagnetic reversing valve is also different. The sampling test of the electromagnetic reversing valve in the prior art is often ignored by some manufacturers due to the complicated operation and large test data. However, the sampling test of the electromagnetic reversing valve is also an important part of its quality inspection. Usually, the sampling test of the electromagnetic reversing valve mainly relies on manually installing the electromagnetic reversing valve to be tested on the test bench with screws, and then inserting the power plug into the electromagnetic reversing valve to be tested. The operation is time-consuming and laborious. Low efficiency; and when doing type tests on different items of electromagnetic reversing valves with different functions, it is necessary to re-build the connecting oil circuit, the workload is relatively large, and the test data generally depends on the staff to observe the instrument readings with the naked eye, and the test data is more. The accuracy is not high, which wastes labor and time, and the judgment of the test performance of more than a dozen kinds of electromagnetic reversing valves requires experienced technicians to complete, which is difficult for ordinary employees and affects the production and shipment of the manufacturer. It is very important for automatic equipment to realize automatic testing of electromagnetic directional valves to improve the quality of electromagnetic directional valves
