The invention belongs to the field of fluid machinery, and relates to an overload self-adaptive oil supply valve. The valve comprises an upper shell, a lower shell, an inertia valve element, a spring, a plurality of sealing rings and the like, wherein runners are arranged in a flow guide core of the lower shell and the inertia valve core to communicate an inlet and an outlet of the valve and balance the fluid pressure of the inlet and the outlet of the valve, spring force, frictional resistance between the flow guide core and the inertia valve core, resistance of fluid to the inertia valve core, gravity of the inertia valve core and overload inertia force of the inertia valve core are balanced, in an overload environment, overload inertia force of the inertia valve core is responded through spring force, rapid balance is achieved under the influence of friction resistance between the flow guide element and the inertia valve core and resistance of fluid to the inertia valve core, and adjustment of flow resistance and flow capacity of an oil supply pipeline is achieved.
本发明属于流体机械领域,涉及一种过载自适应供油阀。该阀包括上壳体、下壳体、惯性阀芯、弹簧、多个密封圈等组成部分。下壳体的导流芯及惯性阀芯内部设有流道沟通阀入口与出口,平衡阀入口与出口流体压力。弹簧力、导流芯与惯性阀芯的摩擦阻力、流体对惯性阀芯的阻力、惯性阀芯重力和惯性阀芯过载惯性力平衡。在过载环境,通过弹簧力响应惯性阀芯过载惯性力,并在导流芯与惯性阀芯的摩擦阻力、流体对惯性阀芯的阻力影响下迅速平衡,实现对供油管路流阻和流通能力的调节。
