Method for Determining of the Valve Cavitation Characteristics

Reliable and safe operation of piping systems depends on the cavitation processes occurring in its environment. Based on the analysis of cavitation processes’ studies, the existing methods of cavitation characteristics’ determination and experience in the use of GOST R 55508-2013 the authors proposed a method of experimental determination of the cavitation coefficient and developed the technique of experimental data processing when determining these coefficients. Based on the experimental data, the authors make conclusions about the influence of pressure before and after the tested valve and the differential pressure flow on the bandwidth characteristic and cavitation characteristic of valves.
