Abstract

V okviru diplomskega dela je prikazan razvoj dvostopenjskega varnostnega ventila za vodo, uporabljenega za pretoke do 50 l/min in tlake do 400 bar. Začetek diplomskega dela sestavljata pregled trga obstoječih komponent in predstavitev lastnosti vode. V nadaljevanju so prikazani razvoj in konstruiranje ventila ter njegova izdelava. Nato sledi numerična analiza obravnavanega ventila z metodo končnih elementov. Na koncu so izvedeni še preizkusi na obravnavanem ventilu. Rezultat diplomskega dela je delujoč ventil za območje vseh tlakov in pretokov, ki izraža majhno puščanje in dober odziv na nihanje tlaka. Pri preizkusih smo prišli do ugotovitev, da se ventil ne zapira dovolj dobro. V zadnjem delu diplomskega dela smo v ta namen prikazali še rešitev problema in izvedli preizkuse z novo izvedbo. Preizkusi so pokazali pravilno delovanje ventila.

Secondary title: Redesign of double-stage water hydraulic pressure relief valve
Secondary abstract: The following thesis presents the development of a two-stage safety valve for water used for flows of up to 50 l/min and pressures of up to 400 bar. Presented in the beginning of the thesis is an overview of the existing components on the market as well as a presentation of the properties of water. The development, construction and production of the valve are shown next. Then follows the numerical analysis of the valve using the finite element method. Finally, the valve in question is being tested. The result of the thesis is a functioning valve for the range of all pressures and flows, which exhibits low leakage and good response to pressure fluctuations. During testing, we came to the conclusion that the valve does not close well enough. This is why, in the last part of the thesis, we presented a solution to the problem and conducted tests with a new implementation. Tests have shown that the valve is functioning properly.
