The invention belongs to the field of hydraulic control, and particularly relates to a multi-way valve with microswitches and a torque integrated control system.The multi-way valve comprises a first oil inlet unit, a telescopic control unit, a variable amplitude control unit and a winch control unit; the telescopic control unit comprises a telescopic reversing valve, a telescopic unit microswitch is arranged on an end cover of the telescopic reversing valve, and a telescopic unit valve element push rod movably arranged on the telescopic reversing valve is configured to control opening and closing of the telescopic unit microswitch. The variable-amplitude control unit comprises a variable-amplitude reversing valve, a variable-amplitude unit microswitch is arranged on an end cover of the variable-amplitude reversing valve, and a variable-amplitude unit valve element push rod movably arranged on the variable-amplitude reversing valve is configured to control opening and closing of the variable-amplitude unit microswitch. Microswitches are installed on end covers of a multi-way valve telescopic control unit, a variable amplitude control unit and a winch control unit, valve element push rods are driven by movement of valve elements of all the units to achieve opening and closing of the microswitches, and a moment system confirms whether the moment limiting recognition function needs to be started or not according to the opening and closing states of the microswitches.

    本发明属于液压控制领域,具体涉及一种具有微动开关的多路阀及力矩集成控制系统,多路阀包括第一进油联、伸缩控制联、变幅控制联和卷扬控制联;伸缩控制联包括伸缩换向阀,伸缩换向阀的端盖上设置有伸缩联微动开关,可动地设置在所述伸缩换向阀上的伸缩联阀芯推杆被配置为控制伸缩联微动开关的启闭;变幅控制联包括变幅换向阀,变幅换向阀的端盖上设置有变幅联微动开关,可动地设置在所述变幅换向阀上的变幅联阀芯推杆被配置为控制变幅联微动开关的启闭。在多路阀伸缩控制联、变幅控制联及卷扬控制联的端盖上安装微动开关,通过各联阀芯运动带动阀芯推杆实现微动开关的启闭,力矩系统根据微动开关的启闭状态来确认是否需要开启力矩限制识别功能。
