| description | The utility model discloses an integrative hydraulic multi-way directional valve, the integrative type valve body(1) is provided with the directional valve that comprises a plurality of ways of valve rod apparatus(2); the valve hole of each valve rod(2) inside the valve body(1) is distributed and provided with the oil return cavity(T1'), the upper working oil cavity(A'), oil inlet cavity(P1'), the lower working cavity(B'), the lower oil return cavity(T2'), the unloading oil cavity(T3'a), the lower unloading oil cavity(T3'b) and corresponding oil lanes; and the upper unloading oil cavity(T3'a) and the lower unloading oil cavity(T3'b) on the valve hole of adjacent two valve rods(2) are respectively communicated with the oil lane hole(T3', T3' ') which is opened by the vertical drilling to the valve rod(2) arranging face, each oil lane hole(T3') and(T3' ') are opened by staggered and separately distribution; and the upper unloading oil cavity(T3'a), the lower unloading oil cavity(T3'b) and oil lane hole(T3', T3' ') are formed the twisted unloading oil lane(T3). The utility model has advantages as follows: simple structure, good manufacturing and processing, smooth turning of unloading oil lane T3, small pressure lost, reliable for using and good performance. |
