The invention provides a water hydraulic temperature adjustment valve and an adjustment system based on a bionic principle. The water hydraulic temperature adjustment system comprises filters, a hydraulic pump, an electromagnetic reversing valve, an execution system loop, a temperature control valve, a control circuit, a refrigerator, a heater and a water tank, wherein the major temperature control valve mainly comprises a valve cover, a valve body, a bionic erosion-resistant valve core, a ratio electromagnet and a control module; the control valve comprises a water inlet and two water outlets; the two water outlets are connected with a heating loop and a refrigerating loop respectively; water enters the valve body through the water inlet and then is respectively led to water inlets of a heat dissipation loop and the refrigerating loop; after the temperature sensor measures the temperature of the water medium, the control circuit controls the ratio electromagnet to control the opening degrees of two valve openings to realize precision control over the temperature. The water hydraulic temperature adjustment valve and the adjustment system mainly provide good temperature control over water hydraulic media, so that the working stability of a water hydraulic system is guaranteed.
