The utility model relates to a combined hydraulic block which comprises a block body which is integrally formed and used for installing a three-position two-way electromagnetic valve and a proportional overflow valve, one end of the upper surface of the block body is used for installing the three-position two-way electromagnetic valve, and a liquid return opening, a valve inlet and a valve outlet are formed in one end of the upper surface of the block body. A liquid inlet is formed in one end, adjacent to one end of the upper surface of the block body, of the side surface of the block body, a liquid return channel is communicated between the liquid inlet and the liquid return opening, and the other end, provided with the liquid inlet, of the side surface of the block body is used for installing a proportional overflow valve. A high-pressure inlet and a high-pressure outlet which are communicated with the proportional overflow valve are formed in the other end of the side surface of the block body, a liquid ou
