20.500.12556/RUL-94470 Oblikovanje čepa regulacijskega ventila Design plug for control valve V magistrski nalogi je predstavljena analiza vpliva oblike in velikosti regulacijskega čepa na pretočni koeficient v ventilu. Narejena je primerjalna analiza med numeričnim izračunom in eksperimentalnimi rezultati. V nalogi je opisano fizikalno ozadje delovanja ventila, na podlagi katerega so izvedeni numerični izračuni ter prikazana merilna oprema s katero so bili izvedeni eksperimenti. Tako preizkuševališče kot tudi preizkušanec so izdelani po veljavnih standardih za merjenje ventilov. Na obstoječem sistemu za preizkušanje smo eksperimentalno ovrednotili merilno negotovost prototipnega ventila pri merjenju pretočnega koeficienta. This work represents the analysis how shape and size of regulation plug influences the valve flow coefficient. Focus is on comparison analysis between numerical calculations and experimental results. In the work, there is also physical background of valve operation based on what numerical calculations were made and overview of measurement equipment used for experiments. Measurement equipment and test samples are prepared per valid standards for valves measurements. On the existing measuring equipment, we quantified also measurement uncertainty when measuring flow coefficient on prototype valve. regulacijski ventil pretočni koeficient oblika in velikost čepa eksperimentalna analiza regulational valve flow coefficient shape and size plug experimental analysis true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-08-30 07:15:24 2017-08-30 07:15:25 2022-08-10 01:43:34 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 199137 650.pdf 650.pdf 1 55638C5FD4D56A9C1BFC9F05E33EC90D f2c3d75c21e2d63ad9a50c0af3619411c2d8dbbd2d2e895f0f204a31169b207e 87190295-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/72db26f0-d337-48ad-af47-5fae79d17a73 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=102691 Fakulteta za strojništvo 0 0 0
