The invention discloses a hydraulic motor balance valve group with energy recovery and safe release functions. A balance valve, a hydraulic control reversing valve and a shuttle valve are arranged in the balance valve group, and a port A and a port B of the balance valve group respectively communicate with an external oil supply way; the port A of the balance valve group communicates with a port A1 of a hydraulic motor through the balance valve and a first oil way; the port B of the balance valve group communicates with a port B1 of the hydraulic motor through a third stop valve and a second oil way; and the balance valve group is further provided with a first electromagnetic reversing valve and an eighth stop valve, a port a of the first electromagnetic reversing valve communicates with the first oil way, a port b of the first electromagnetic reversing valve communicates with a port b of the eighth stop valve through a third oil way, a port a of the eighth stop valve communicates with a port XQ of the balance valve group, and the port XQ of the balance valve group is connected with an external energy accumulator. The hydraulic motor balance valve group has the beneficial effect of solving the problems that safe release cannot be achieved at a low tension value, released potential energy recycling cannot be achieved, and the motor is rapidly overheated due to the too low release speed.

    本发明公开了一种具备能量回收及安全释放功能的液压马达平衡阀组,平衡阀组内设平衡阀、液控换向阀和梭阀,平衡阀组的A口和B口分别与外部供油路连通;平衡阀组的A口经平衡阀和第一油路与液压马达的A1口连通;平衡阀组的B口经第三截止阀和第二油路与液压马达的B1口连通;所述平衡阀组还设有第一电磁换向阀和第八截止阀,第一电磁换向阀的a口与第一油路连通,第一电磁换向阀的b口通过第三油路与第八截止阀的b口连通,第八截止阀的a口与平衡阀组的XQ口连通,平衡阀组的XQ口与外置的蓄能器相连。本发明的有益效果为:解决了不能以低张力值安全释放、不能实现释放势能回收再利用以及释放速度过低马达快速过热的问题。
