The invention provides a rotation buffering balance valve block which comprises a buffering valve block, the buffering valve block is connected with a rotation system of a crane, the buffering valve block comprises an oil tank, a balance valve set, a control valve set, a first rotation oil way, a second rotation oil way and an output oil way, and the oil inlet end of the first rotation oil way is connected with the oil tank; the oil outlet end of the first rotation oil way is connected with a first oil outlet of the output oil way. The oil inlet end of the second rotation oil way is connected with the oil tank, and the oil outlet end of the second rotation oil way is connected with a second oil outlet of the output oil way. The balance valve group is arranged on the first rotary oil way and the second rotary oil way, and the output oil way is connected with a rotary system of the crane; by means of the balance valve block, the crane is stable during rotation starting, backflow pressure impact of hydraulic oil can be reduced during rotation stopping, and rotation action stopping is stable.

    本发明提供一种回转缓冲平衡阀块,包括缓冲阀块,所述缓冲阀块连接吊机的回转系统,所述缓冲阀块包括油箱、平衡阀组、控制阀组、第一回转油路、第二回转油路和输出油路,所述第一回转油路的进油端连接油箱,第一回转油路的出油端连接输出油路的第一出油口;所述第二回转油路的进油端连接油箱,第二回转油路的出油端连接输出油路的第二出油口;所述平衡阀组设置在第一回转油路和第二回转油路上,所述输出油路连接吊机的回转系统;通过本发明的平衡阀块,使得吊机在回转启动时平稳,回转停止时也可以降低液压油的回流压力冲击,使得回转动作停止稳定。
