In use, hydraulic oil flows from the flow hole 33 above the valve body 3 to the valve disc 4 and flows out from the chamber of the valve disc 4 and the valve disc outlet 44 in sequence to conduct downward impact force to the shock absorption damping mechanism; the diversion trench 35 arranged above the valve body 3 can disperse the hydraulic oil flowing to the upper part of each flow hole 33, so that the flow rate of the hydraulic oil flowing into each flow hole 33 is uniform; the flow baffle block 43 in the cavity plays a role in buffering hydraulic oil, so that the hydraulic oil can be prevented from generating bubbles, and the service life of the hydraulic oil is prolonged; the groove 45 can play a role in draining the hydraulic oil flowing out; the cooperation of the flow hole 33, the flow guide groove 35, the cavity, the flow blocking block 43 and the valve disc outlet 44 can play a role in shock absorption.
