VALVE GROUP

WIPO Patent Application WO/2023/082233

A1

A valve group, comprising a valve plate (1), and a hydraulic reversing valve (2), an electromagnetic valve (3), a hydraulic lock group, a sequence valve (4) and a first overflow valve (7) provided on the valve plate (1). The valve plate (1) comprises a first side (101), a second side (102) and a third side (103) that are adjacent in pairs. The hydraulic reversing valve (2), the electromagnetic valve (3), and the hydraulic lock group are respectively arranged on the first side (101). The hydraulic reversing valve (2) is arranged between the electromagnetic valve (3) and the hydraulic lock group. The electromagnetic valve (3) is close to a vertex angle where the first side (101), the second side (102) and the third side (103) intersect. The sequence valve (4) is provided on the second side (102), and the first overflow valve (7) is provided on the third side (103). A plurality of valves of the valve group are arranged on different sides of the valve plate, such that the three-dimensional space can be effectively utilized, the distances between the communicated valves are ensured to be the shortest, the spatial arrangement of the plurality of valves is reasonable, the volume of the valve group can be reduced, the degree of integration of the valve group is improved, and the occupied space of the valve group is smaller.
