| description | The utility model relates to an annular hydraulic valve group structure for controlling an offshore pile hammer. A P valve two-stage pilot valve, an R valve two-stage pilot valve and an S valve are respectively arranged at the outer ring part of the annular hydraulic valve group structure; four P valve oil inlets are formed in the upper end face of the annular hydraulic valve set structure and used for being connected with an oil tank and a P valve first-stage pilot valve. Four R valve oil inlets are formed in the upper end face of the annular valve hydraulic set structure and used for being connected with an oil tank and an R valve first-stage pilot valve. An S valve oil port is formed in the upper end face of the annular hydraulic valve set structure and connected with an oil tank and a pile hammer hydraulic cylinder. On the basis of hydraulic valve structures of domestic and overseas pile drivers, an annular valve group structure convenient to mount on an offshore pile driver is designed; the annular valve |
