The invention discloses a confluence type throttling speed regulation multi-way valve and accelerator linkage control system which comprises a large pump oil inlet unit, a telescopic control unit, a variable amplitude control unit, a winch control unit, an oil return unit, a rotation control unit and a small pump oil inlet unit which are connected in parallel. Each of the telescopic control unit, the variable amplitude control unit, the winch control unit and the rotation control unit comprises a one-way valve, a reversing valve, a first electric proportional reversing valve and a second electric proportional reversing valve; according to the scheme, each control link in the multi-way valve is integrated with an electric proportional pressure reducing valve to realize a proportional relation between the axial opening degree of the main valve and an input electric signal, so that electric control throttling speed regulation control is realized; the accelerator linkage control system can achieve stable low-speed operation of a small opening of the multi-way valve and continuous accelerated operation of a large opening of the multi-way valve, and the speed regulation interval is enlarged.
本发明公开了一种合流型节流调速多路阀及油门联动控制系统,包括并联连接的大泵进油联、伸缩控制联、变幅控制联、卷扬控制联、回油联、回转控制联及小泵进油联;所述伸缩控制联、变幅控制联、卷扬控制联、回转控制联均包括单向阀、换向阀、第一电比例换向阀和第二电比例换向阀;本方案中多路阀中的各控制联集成上电比例减压阀,来实现主阀轴向开度与输入电信号之间成比例关系,从而实现电控节流调速控制;油门联动控制系统能够实现多路阀小开口稳定低速运行,大开口不断加速运行,扩大调速区间。
