It is universal requirement for the typical hydraulic system realizing integrity andstandardrization to develop the integrated disposition of hydraulic valves. As the carrier of allkinds of valves, hydraulic manifold block (HMB) is one of the key parts of integratedhydraulic system. According to a general survey of foreign and domestic circumstance ofstudy at present, HMB design mainly focus on the structure design for the angle of valveslayout at outer and holes arrangement at inner of hexahedron...
