Hydraulic reversing valve for safety overflow valve

The utility model relates to the field of hydraulic transmission, in particular to a hydraulic reversing valve for a safety overflow valve, which comprises a reversing valve body, and a circulation pipeline is arranged on the surface of the reversing valve body and communicated with the inside of the reversing valve body. The filtering mechanism is arranged in the reversing valve body, and the surface of the filtering mechanism penetrates through the exterior of the reversing valve body; the filtering mechanism comprises a filtering assembly arranged in the reversing valve body. Through the arrangement of the filtering assembly, impurities circulating in a circulating pipeline are filtered and guided through a filtering plate, the impurities will flow into an arc-shaped pipeline to make contact with a guiding hopper, the impurities will be discharged downwards under the guiding effect of the inner side conical face of the guiding hopper, and therefore the impurities below are prevented from rising again; and
