Abstract

The bachelor thesis deals with the methodology of measuring the characteristics of ball valves of different diameters. In the theoretical part it deals with problems of hydraulic losses in pipes, pressure and flow gauges. In the thesis, the experimental hydraulic circuit according to ČSN 60534-2-3 is designed and measurement methodology is developed. In the practical part of the thesis is measured the ball valve for 3 different diameters, each ball valve is measured for 4 different positions of opening. The thesis deals with the flow coefficient and the loss coefficient. For clarity, measured and calculated values are converted into graphical form and compared to the literature.
