Měření charakteristiky ventilu na vodní trati

Abstract

This Bachelor thesis deals with measuring the characteristics of the valve on the water line. In the introduction physical properties of fluids, flow measurement characteristics, the characteristics of measuring the local speed, and characteristics of measuring the pressure at the water line, are defined. In the practical part, the experimental track was proposed, where the subsequent measurement took place itself. The characteristics of the globe valve were measured in several positions. The measurement was carried out on the water line with induction flow meter and a differential pressure gauge. The results of measuring the characteristics of the globe valve were evaluated using tables and graphical relations. In conclusion, the results of differential pressure gauge measurement were compared with the results of U-Tube measurement.
