[0031] This embodiment provides a device for dual-valve testing to perform performance tests on solenoid valves. The testing device is compatible with performance tests of multiple solenoid valves, has a simple structure, and has strong stability. It can quickly switch between tests on different solenoid valves. Compared with traditional testing devices, it is more convenient to use and has higher testing efficiency.

[0032] Combination Figures 1 to 5As shown, the testing device of the present embodiment comprises a valve body 10, a test flow channel 20 and a reversing member 30. The valve body 10 of the present embodiment is a valve block having a plurality of accommodating cavities 11 on its surface for placing the solenoid valve to be tested. The performance of the solenoid valve to be tested located in the accommodating cavity 11 is tested through the test flow channel 20, and the reversing member 30 can switch the test flow channel 20 to achieve performance testing of different solenoid valves. There are a plurality of test flow channels 20 in the valve body 10 of the present embodiment, and the test flow channels 20 inside the valve body 10 are staggeredly distributed. Under the action of the reversing member 30, the flow switching of the test flow channel 20 is achieved, thereby achieving effective testing of the solenoid valve.

[0033] In this embodiment, an oil inlet 12 and an oil outlet 13 are provided on the valve body 10. The oil inlet 12 is the starting end of the test flow channel 20, and the oil outlet 13 is the terminal end of the test flow channel 20. The oil inlet 12 and the oil outlet 13 of this embodiment are fixed in position, and the number of the test flow channels 20 is several, indicating that several test flow channels 20 share the oil inlet 12 and the oil outlet 13. In actual use, the test oil enters from the oil inlet 12 and passes through the test flow channel 20 to test the solenoid valve. After the test is completed, the test oil will be discharged from the oil outlet 13, and the test condition of the solenoid valve can be judged according to the oil discharge condition of the oil outlet 13.

[0034] Specifically, the number of test channels 20 in this embodiment is several and they are located in the valve body 10, the accommodating chamber 11 is located in the test area of ​​the test channel 20, and the accommodating chamber 11 is on the test path of the test channel 20, thereby ensuring that the solenoid valve can be tested smoothly through the test channel 20, which means that the solenoid valve to be tested is located on the test path of the test channel 20, that is, the performance test of the solenoid valve to be tested is realized by the test channel 20. During the testing of the solenoid valve, the solenoid valve is placed in the accommodating chamber 11, and the accommodating chamber 11 is located on the test path of the test channel 20. Therefore, the test oil enters from the oil inlet 12, and when passing through the test path of the test channel 20, it will pass through the solenoid valve smoothly to realize the leakage test of the solenoid valve.

[0035] Combination Figure 2 , Figure 3 as well as Figure 4As shown, the reversing member 30 is arranged on the valve body 10, and the reversing member 30 is used to switch different test flow channels 20. The reversing member 30 of this embodiment includes a first reversing member 301, a second reversing member 302 and a third reversing member 303. Under the cooperation of the first reversing member 301, the second reversing member 302 and the third reversing member 303, the test flow channel 20 is quickly switched by rotating the first reversing member 301, the second reversing member 302 and the third reversing member 303, thereby realizing the test switching of the solenoid valve. In actual operation, the reversing member 30 of this embodiment, the first reversing member 301, the second reversing member 302 and the third reversing member 303 can be operated separately or in combination to realize stable switching of the test flow channel 20. The switched test flow channel 20 can switch the test of the solenoid valve.

[0036] In this embodiment, there are two solenoid valves to be tested, including a first solenoid valve 100 and a second solenoid valve 200. When the first solenoid valve 100 is tested, oil enters from the oil inlet 12, and the first solenoid valve 100 is tested using the second reversing member 302. At this time, the first reversing member 301 and the third reversing member 303 are locked and cannot flow. The oil flows through the second reversing member 302 and then passes through the first solenoid valve 100. If the test oil is successfully discharged from the oil outlet 13, the first solenoid valve 100 is tested. 00's performance test is qualified, otherwise it is unqualified. When the second solenoid valve 200 is tested, oil enters from the oil inlet 12, and the first reversing member 301 and the third reversing member 303 are used to test the second solenoid valve 200. At this time, the second reversing member 302 is locked and cannot flow. The oil flows through the first reversing member 301, passes through the second solenoid valve 200, and then flows through the third reversing member 303, and is discharged from the oil outlet 13. That is, the performance test of the second solenoid valve 200 is qualified, otherwise it is unqualified.

[0037] In this embodiment, a plurality of oil holes 31 are provided on the switching member 30. The oil holes 31 correspond to the positions of the test flow channels 20. There are at least two oil holes 31, which are spaced apart along the length direction of the switching member 30. The directions of the oil holes 31 in this embodiment are different. After the switching member 30 rotates, the oil holes 31 are used to switch different test flow channels 20. The oil holes 31 can connect the test flow channels 20. By switching the oil holes 31, the switching of different test flow channels 20 is realized, thereby realizing the performance test of different solenoid valves. The existence of the oil holes 31 can quickly switch the test path of the test flow channel 20. By rotating the switching member 30, the oil holes 31 can turn on or off different test flow channels 20, thereby realizing the switching operation of the test flow channel 20, thereby realizing the leakage test of different solenoid valves.

[0038] Furthermore, a slot 14 is provided on the valve body 10 of the present embodiment, and a locking slot 32 is provided on the reversing member 30. The reversing member 30 is connected to the valve body 10 via a locating pin 40. The locating pin 40 passes through the locking slot 32, and the locating pin 40 is located in the slot 14 to lock the reversing member 30. The locating pin 40 passes through the locking slot 32, so that the locating pin 40 is located in the slot 14 to complete the locking of the reversing member 30. The slot 14 of the present embodiment is a cross-shaped structure to meet the rotation requirements of the reversing member 30. When the reversing member 30 rotates, the direction of the locking slot 32 will also change accordingly. The slot 14 is a cross-shaped structure, which can cooperate with the locating pin 40 to place the locating pin 40 in the slot 14. Since the locating pin 40 passes through the locking slot 32, the locating pin 40 realizes the locking of the reversing member 30.

[0039] In actual use of the test device of this embodiment, the first solenoid valve 100 and the second solenoid valve 200 are respectively placed in the corresponding accommodating chamber 11 on the valve body 10, and the first reversing member 301, the second reversing member 302 and the third reversing member 303 are used to switch the test flow channel 20. The reversing member 30 is provided with an oil hole 31. When it is necessary to switch the test flow channel 20, since the directions of the oil holes 31 are different, when the reversing member 30 rotates, the oil holes 31 will switch different test flow channels 20. The oil holes 31 can connect or block the test path of the test flow channel 20. By switching the oil holes 31, the switching of different test flow channels 20 is achieved. Combined with the present embodiment, the number of solenoid valves to be tested in this embodiment is two, including the first solenoid valve 100 and the second solenoid valve 200. When the first solenoid valve 100 is tested, the test oil enters from the oil inlet 12, and the second reversing member 303 is used. The first solenoid valve 100 is tested by the first reversing member 302. At this time, the test flow channel 30 of the first reversing member 301 and the third reversing member 303 is locked and cannot flow under the action of the oil hole 31. At this time, the oil flows through the second reversing member 302, and then passes through the first solenoid valve 100. If the test oil is discharged from the oil outlet 13 smoothly, the performance test of the first solenoid valve 100 is qualified, otherwise it is unqualified. When the second solenoid valve 200 is tested, the test oil enters from the oil inlet 12, and the second solenoid valve 200 is tested by the first reversing member 301 and the third reversing member 303. At this time, the test flow channel 30 of the second reversing member 302 is locked and cannot flow under the action of the oil hole 31. The test oil flows through the first reversing member 301, passes through the second solenoid valve 200, and then flows through the third reversing member 303, and is discharged from the oil outlet 13, that is, the performance test of the second solenoid valve 200 is qualified, otherwise it is unqualified.

At this time, the oil flows through the second reversing member 302 and then passes through the first solenoid valve 100. If the test oil is successfully discharged from the oil outlet 13, that is, the first solenoid valve 100 is tested. The performance test of the magnetic valve 100 is qualified, otherwise it is unqualified. When the second solenoid valve 200 is tested, the test oil enters from the oil inlet 12, and the first reversing member 301 and the third reversing member 303 are used to test the second solenoid valve 200. At this time, the test flow channel 30 of the second reversing member 302 is locked and cannot flow under the action of the oil hole 31.
