Abstract:This bachelor thesis deals with the calculation of the torque on the output shaft of the four-concentric butterfly valves and experimental measurement of this torque on real manufactured valves. At the beginning is carried out a brief research, the purpose describe the basic components of the butterfly valves, its production variants of the offset disc, eventually types of fittings to piping. The main part describes the partial torque occurring on the individual components. Following data from the performer measurement and at the end are compared obtained results.

Student prezentoval komisi svoji bakalářskou práci a následně odpověděl úplně a správně na otázky oponenta i další otázky členů komise: Jak byly stanoveny krouticí momenty v ložiscích uložení? Jak jste stanovoval součinitel smykového tření a co má na jeho hodnotu vliv? Jaký je poměr mezi momentem od odtrhávání vírů a dynamického momentu od uzavírání klapky?
