The invention belongs to the technical field of valves, and particularly relates to a cam flexing control valve suitable for working conditions of high pressure difference and solid particle containing. The cam flexing control valve suitable for the working conditions of the high pressure difference and the solid particle containing comprises a valve body, a valve element assembly, a valve seat, avalve rod, a guide column, an upper guide sleeve, a lower guide sleeve and a ring pressing nut. The valve is capable of stably running for a long period under the working conditions of the high pressure difference, and especially medium containing the large amount of solid particles. 本发明属于阀门技术领域，具体涉及一种适用于高压差含固体颗粒工况的凸轮挠曲调节阀。本发明提供的适用于高压差含固体颗粒工况的凸轮挠曲调节阀调节阀包括：阀体、阀芯组件、阀座、阀杆、导向柱、上导向套、下导向套和压圈螺母；其可在高压差，尤其是介质中含有大量固体颗粒的工况下，长周期稳定运行。
