[0002] Conventional testing of solenoid valves includes: high-voltage continuity test, resistance test, solenoid valve energized stroke test, and solenoid valve on / off return test. After the electromagnet test is completed, it needs to be marked with a code. This testing process is performed after product assembly and needs to be implemented in steps: first, the resistance test is performed; then the high-voltage continuity test is performed; next, the solenoid energized stroke test is performed; then the on / off return test is performed; finally, the code is printed. Patent number CN201320627988.5 discloses a multi-functional testing mechanism for solenoid valves, including a first proximity sensor, a support base, a guide rail, a high-voltage tester, a constant current power supply, a lead screw, a servo motor, a cylinder, a laser displacement sensor, an inkjet printer, and an industrial control computer. The first proximity sensor is adjacent to the support base, which is located on the guide rail. A cylinder is installed between the support base and the guide rail. The support base has a continuity connection probe electrically connected to the high-voltage tester and the constant current power supply. The support base is connected to the servo motor via a lead screw. The high-voltage tester, laser displacement sensor, and inkjet printer are all adjacent to the guide rail. The industrial control computer is electrically connected to the first proximity sensor, high-voltage tester, servo motor, laser displacement sensor, and inkjet printer. Through this method, this invention can perform high-voltage conduction, resistance, solenoid valve energization stroke, and solenoid valve on / off return tests on the solenoid valve at the same workstation, ensuring no material mixing or defective products are released during functional testing, and completing the test in a short time. However, this equipment lacks the function of noise detection and stability testing of the solenoid valve during operation. If these two tests are required, the valve needs to be moved to another workstation, which is cumbersome. Therefore, this invention proposes a three-way solenoid valve energization testing device.
