The invention discloses a structure for reducing oil return impact of a hydraulic valve. The structure comprises a valve body, wherein an output cavity and an oil return cavity which communicate withan oil cavity of the hydraulic valve are formed in the valve body in the vertical direction; a valve element, a steel ball and a spring assembly are sequentially arranged in the output cavity from topto bottom; a plug is arranged at the lower end of the oil return cavity; a horizontal opening cavity which penetrates through the output cavity and the oil return cavity is further formed in the right side of the valve body; a throttling sheet is arranged in the horizontal opening cavity; liquid return oil is carried to the oil return cavity through the output cavity and the throttling sheet; andan end cover is further arranged at the right end of the horizontal opening cavity. According to the structure for reducing oil return impact of the hydraulic valve, the problem that output pressureof the hydraulic valve shakes due to too high oil return pressure is effectively avoided by reducing pressure impact generated in the oil return process of the hydraulic valve, and meanwhile, the mounting space is further saved.
Description
technical field [0001] The invention belongs to the field of hydraulic valves, in particular to a structure for reducing the impact of oil return for a hydraulic valve. Background technique [0002] At present, hydraulic valves have been widely used in the mechanical field. With the development of technology, there are more and more types of hydraulic valves. However, excessive oil return shock has always been a problem that plagues the stable output of hydraulic valves. In order to solve this problem, now There is a technology to connect a throttle valve outside the oil return line. Due to the limitation of installation space, some equipment does not allow an additional throttle valve. In order to better solve the problem of excessive oil return impact, higher requirements are put forward for the structural design of hydraulic valves to reduce oil return impact. Contents of the invention [0003] The invention provides a structure for reducing the oil return impact of a ...
