When the hydraulic oil entering the inside of the multi-way hydraulic valve body 1 is filtered through the filter valve 3, the impurities in the hydraulic oil are filtered on the first filter screen 4 and remain on the first filter screen 4. When the impurities continuously accumulate on the first filter screen 4, the filter valve 3 is blocked, so it is necessary to regularly clean the first filter screen 4 through the cleaning ring 5 to scrape off the impurities on the surface of the first filter screen 4. Only the impurities are scraped off from the first filter screen 4, and the impurities cannot be effectively treated. When the hydraulic oil flows again, a large amount of impurities in the filter valve 3 will again accumulate on the surface of the first filter screen 4. Therefore, the filter valve 3 is divided into two spaces by the partition plate 6. The scraped impurities will enter the space at the bottom of the partition plate 6 under the action of gravity. The impurities are collected at the bottom. Under the action of the lifting mechanism, when the cleaning ring 5 is pressed to the bottom, the partition plate 6 rises to form a gap between the connecting seat 7, so that the impurities in the hydraulic oil can enter the bottom of the partition plate 6. Through the device, the filtering capacity of the filter valve 3 can be maintained for a long time, and the flow of the hydraulic oil is not affected.

[0030] As a preferred technical scheme of the embodiment, the top of the cleaning ring 5 is fixedly installed with connecting rods 16 on both sides, and the top of the two connecting rods 16 is fixedly connected with a handle 17 penetrating through the top of the filter valve 3.
