The invention discloses a closed rotary buffer valve which comprises a closed pump, a rotary motor and a rotary buffer module, and the rotary buffer module comprises a stop valve set, a first electromagnetic valve, a second electromagnetic valve and a buffer valve set. A first port of the rotary motor is connected with a first port of the stop valve set and a first port of the first electromagnetic valve, a second port of the rotary motor is connected with a second port of the stop valve set and a second port of the second electromagnetic valve, and the second port of the first electromagnetic valve is further connected with the first port of the second electromagnetic valve. A third port of the stop valve set is connected with a first port of the buffer valve set, and a second port of the buffer valve set is connected with a second port of the first electromagnetic valve. By the adoption of the technical scheme, when the rotation action stops, the rotation buffering module is communicated with the two sides of the rotation motor, the instant pressure difference between the two sides is reduced, and the better buffering and impact preventing effects are achieved.

    本发明公开了一种闭式回转缓冲阀,包括:闭式泵、回转马达和回转缓冲模块,其中:回转缓冲模块包括截止阀组、第一电磁阀、第二电磁阀和缓冲阀组;回转马达的第一端口分别与截止阀组的第一端口和第一电磁阀的第一端口连接,回转马达的第二端口分别与截止阀组的第二端口和第二电磁阀的第二端口连接,第一电磁阀的第二端口还和第二电磁阀的第一端口连接,截止阀组的第三端口与缓冲阀组的第一端口连接,缓冲阀组的第二端口与第一电磁阀的第二端口连接。采用上述技术方案,在回转动作停止时,回转缓冲模块连通回转马达的两侧,降低两侧之间的瞬间压差,实现更好的缓冲和防止冲击的效果。
