Abstract

Ventili su elementi koji se koriste pri regulaciji protoka fluida u industrijskom, vojnom,
komercijalnom i prometnom sektoru. Oni svojim djelovanjem utječu na parametre procesa i
to tako da povećavaju ili smanjuju protok, tlak ili posredno temperaturu medija koji struji
kroz njih. Kretanjem zapornog elementa, u smjeru toka ili suprotno toku medija, kod
zapornih ventila se regulira protok medija u cjevovodu potpunim ili djelomičnim zatvaranjem
toka.
U ovom radu pri razradi konstrukcijskog rješenja koristi se prirubnički zaporni ventil
DN80 PN40, kojeg proizvodi tvrtka ATM d.o.o. iz Zagreba. Kućište je izrađeno postupkom
lijevanja od materijala GP240GH. Ovaj zaporni ventil je predviđen za rad na temperaturi do
300 °C.
Proveden je analitički proračun prema standardu EN 12516-2, kao i numerička analiza
uz pomoć programskog paketa Abaqus. Njihova svrha je da se utvrdi može li kućište ventila
podnijeti nametnuta mu opterećenja pri radnim i ispitnim uvjetima.
S obzirom na rezultate analize, ponuđen je prijedlog poboljšanja postojećeg
konstrukcijskog rješenja kućišta ventila.

Abstract (english)

Valves are devices which are used for controlling in industry and for military,
commercial and transporation applications. In work they affect on processes parameters, with
decreasing or increasing of flow, pressure or indirectly temperature of medium, which is
flowing in valves. Barrier, which is inside of block valves, is moving toward or backward
and regulate flow with partially or completely shut down flow.
In this thesis, for design solution is used flanged block valve DN80 PN40, which is
manufactured by ATM d.o.o. from Zagreb, Croatia. Housing is made by casting from
material GP240GH. This block valve is used up to 300 °C.
Standard EN 12516-2 is used for analytical calculation and for numerical analysis is
used software Abaqus, for the purposes of handling load at working and testing conditions.
Based on given results, suggestion is made for improving current design solution for
valve housing.
