Step-down multipath reversing valve with two-position two-way hydraulic control valve

The invention relates to a step-down multipath reversing valve with a two-position two-way hydraulic control valve, comprising a maneuvering valve and the two-position two-way hydraulic control valve, wherein the two-position two-way hydraulic control valve is connected to a reversing valve plate of a fifth support leg of the maneuvering valve by bolts, and connecting oil ports (C and D) on the two-position two-way hydraulic control valve are respectively communicated with oil ducts (a2 and a3) on the maneuvering valve; the maneuvering valve comprises a valve body, and an overflow valve, a selection valve, an overload valve, a hydraulic-control one-way valve, 5 groups of reversing valves and 5 groups of one-way valves are sequentially arranged on the valve body; the two-position two-way hydraulic control valve comprises a valve body, and a two-position two-way hydraulic control valve core and a damping rod are arranged in the valve body. The invention has the advantages that: the step-down multipath reversing valve has circular control function on the retraction of five support legs as the two-position two-way hydraulic control valve is arranged, that is to say, the fifth support leg is retracted within the first time under any circumstances, therefore, the accident of frequent damage of the fifth support leg due to asynchronous operation is avoided generating, and the safety operation performance of a truck crane is greatly enhanced.
