Review of the Research on and Optimization of the Flow Force of Hydraulic Spool Valves

As one of the important factors affecting stability slide valves, analysis and research flow force are great significance. In recent years, more experts scholars have conducted in this field, attempting to find methods reduce or utilize hydraulic spool valves. Flow includes steady-state transient force, with having most significant impact on The influencing complex diverse, including cavitation phenomenon, shape throttling groove, jet angle. At present, main ways design structure valve, valve sleeve, channel body. This article mainly reviews definition, calculation methods, factors, for reducing provides a new approach
