The invention discloses a load pressure self-feedback flow regulating valve, and belongs to the application field of hydraulic machinery and motor vehicles. The self-feedback flow regulating valve is provided with four oil ports of a K1 control end, a K2 control end, a P1 output end and a P2 input end, and the P1 output end and the P2 input end are connected with an oil inlet and an oil outlet in a control oil circuit separately; K1 and K2 are two external pressure control ends, and the K2 end and a valve core spring pressure reset are in the same direction; the K1 end is used for controlling the flow regulating valve to tend to flow reduction; the K2 end is used for controlling the flow regulating valve to tend to flow increase, and in use, the K1 end and the K2 end are connected with the corresponding load pressure according to the requirements separately; and the opening degree of the flow valve is controlled through load pressure, and load self-feedback control is formed. According to the self-feedback flow regulating valve, the opening degree of the valve core can be automatically adjusted through the pressure feedback control end, and the purpose of flow regulation is achieved; and compared with a traditional electromagnetic proportional throttle valve, the self-feedback flow regulating valve has the advantages of large flow control range, simple and compact structure and convenient integration in a hydraulic system.

    本发明公开了一种负载压力自反馈流量调节阀,属于液压机械和机动车应用领域。自反馈流量调节阀带有K1控制端、K2控制端、P1输出端、P2输入端四个油口,P1输出端和P2输入端分别连接所控制油路中的进油和出油,K1和K2为两个外接压力控制端,K2端与阀芯弹簧压力复位同向,K1端控制流量调节阀趋于流量减小,K2端控制流量调节阀趋于流量增大,使用时根据需要将K1、K2端分别与对应的负载压力相连,通过负载自身压力控制流量阀的开度,形成负载载荷自反馈控制。本发明通过压力反馈控制端可以自主调整阀芯开度,达到调节流量的目的,与传统的电磁比例节流阀相比具有流量控制范围大,结构简单紧凑,便于在液压系统中集成的特点。
