The invention belongs to the technical field of ships, and discloses a special valve group for a large-flow steering engine. The special valve group comprises a reversing valve, a duplex balance valve and a cartridge valve assembly, wherein a first oil port of the reversing valve is connected with an oil inlet of a hydraulic system; a second oil port of the reversing valve is connected with an oil return port of the hydraulic system; a third oil port of the reversing valve is connected with an output oil port of a first hydraulic system; a fourth oil port of the reversing valve is connected with an output oil port of a second hydraulic system; the duplex balance valve is respectively connected between the third oil port and the output oil port of the first hydraulic system and between the fourth oil port and the output oil port of the second hydraulic system in series; and two ends of the cartridge valve assembly are respectively connected with the output oil port of the first hydraulic system and the output oil port of the second hydraulic system. According to the special valve group for the large-flow steering engine, the duplex balance valve ensures that the reversing valve can be in positive load pressure when the load is in a super-relaxation phenomenon, even if the load of the steering engine is increased, the steering engine can still be stabilized at a set angle, and the steering stabilization performance of the steering engine is ensured.

    本发明属于船舶技术领域,公开了一种大流量舵机专用阀组,包括换向阀、双联平衡阀以及插装阀组件,换向阀的第一油口与液压系统进油口连接,换向阀的第二油口与液压系统回油口连接,换向阀的第三油口与第一液压系统输出油口连接,换向阀的第四油口与第二液压系统输出油口连接,双联平衡阀分别串联在第三油口与第一液压系统输出油口之间以及第四油口与第二液压系统输出油口之间,插装阀组件的两端分别与第一液压系统输出油口以及第二液压系统输出油口连接。本发明提供的大流量舵机专用阀组,双联平衡阀确保换向阀在负载发生超弛现象时,也能够处于正的负载压力,即使舵机的负载增大,舵机仍然可以稳定在设定的角度上,保证舵机的稳舵性能。
