Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve testing, specifically a hydraulic valve testing device. Background Technology

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressurized oil of a pressure regulating valve and is usually used in combination with an electromagnetic pressure regulating valve. In the prior art, a Chinese patent document with application number CN202222202590.9 describes a hydraulic valve testing device. This patent tests the airtightness by connecting the air inlet pipe and tests its pressure resistance by closing the air inlet pipe. It can also perform long-term violent testing to test the service life of the hydraulic valve, improving the comprehensiveness of the test. The test oil in the oil pump can be recycled for a long time after being filtered by the filter box. The distance between the moving rod and the fixed rod can be adjusted to fix the hydraulic valve, improving the practicality of the test of this utility model. In the existing hydraulic valve testing device, the filter screen inside the filter box is easily clogged during use, which is inconvenient to install and replace the filter screen, affecting the filtration speed and bringing certain adverse effects to the user. Therefore, we propose a hydraulic valve testing device. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] This embodiment is a hydraulic valve testing device.

[0022] like Figure 1-4 As shown, the test platform includes a test bench 1, an oil tank 3 on the lower inner surface of the test bench 1, a return oil pipe 2 on one side of the upper outer surface of the test bench 1, a filter box 4 at the lower end of the return oil pipe 2, a filter plate 5 inside the filter box 4, and a replacement mechanism 6 between the filter box 4 and the return oil pipe 2. The replacement mechanism 6 includes a folded pipe 7, a multi-section telescopic rod 8, a connecting plate 9, a slot 10, a filter frame 11, a through groove 12, an insert plate 13, a mounting plate 14, a spring 15, an arc plate 16, and an impact ball 1. 7. The folded pipe 7 is located on the lower outer surface of the return oil pipe 2. The connecting plate 9 is located on the lower outer surface of the folded pipe 7. Two sets of multi-section telescopic rods 8 are located on both sides of the upper outer surface of the connecting plate 9, and the multi-section telescopic rods 8 are located between the test bench 1 and the connecting plate 9. Two sets of insert plates 13 are located on both sides of the lower outer surface of the connecting plate 9. Two sets of slots 10 are respectively opened in the middle of both sides of the upper outer surface of the filter box 4. The filter frame 11 is located at the lower end of the connecting plate 9, and the filter plate 5 is located inside the filter frame 11.

[0023] Two sets of through slots 12 are respectively opened in the middle of the upper outer surface of the filter frame 11. The mounting plate 14 is located on one side of the lower outer surface of the connecting plate 9, and the arc plate 16 is located on one side of the outer surface of the mounting plate 14. The impact ball 17 is located at the lower end of the arc plate 16, and the spring 15 is located at the lower end between the arc plate 16 and the mounting plate 14. The insert plate 13 is inserted into the through slot 12, and the insert plate 13 is snapped into the slot 10. The impact ball 17 is elastically connected to the mounting plate 14 through the spring 15, and the filter frame 11 and the filter box 4 are overlapped.

[0024] It should be noted that this utility model is a hydraulic valve testing device. By activating the multi-section telescopic rod 8, the connecting plate 9 is raised, and the folding tube 7 is folded at the same time. As the connecting plate 9 is raised, the insert plate 13 slides along the slot 10 and through groove 12. After the connecting plate 9 is raised, the filter frame 11 is pulled, and the filter frame 11 slides along the filter box 4. After the filter frame 11 is removed for cleaning and replacement, another set of filter frames 11 is placed on the upper end of the filter box 4. Activating the multi-section telescopic rod 8, the connecting plate 9 is lowered, and the insert plate 13 slides along the through groove 12 and slot 10 at the same time. After the connecting plate 9 limits the filter frame 11, the oil falls along the return oil pipe 2 and falls onto the arc plate 16, compressing the spring 15. This causes the impact ball 17 to strike the filter plate 5, accelerating the filtration speed of the filter plate 5. The filter plate 5 is then reset under the action of the spring 15. This allows for easy installation, disassembly, cleaning, and replacement of the filter frame 11. The impact ball 17 can strike the filter plate 5 to accelerate the filtration speed of the filter plate 5.
