Abstract

En kuleventil (10) omfattende et hus (12) og et innløp (14) og et utløp (16), og et kuleventilelement (34) som er anordnet i huset (12) mellom innløpet (14) og utløpet (16). Kuleventilelementet (34) har en gjennomgående åpning (68) og kan beveges mellom en åpen stilling hvor den gjennomgående åpningen (68) er innrettet i forhold til innløpet (14) og utløpet (16) slik at det derved dannes en fluidstrømningsbane gjennom huset (1 2), og en lukket stilling i hvilken den gjennomgående åpningen (68) ikke er i flukt med innløpet (14) og utløpet (16). Huset (12) har ringformede metallpakninger (74) som er anordnet rundt innløpet (14) og utløpet (16). Disse pakninger (74) samvirker med kuleventilelementet (34) i den lukkede stillingen. Hver pakning (74) innbefatter et i hovedsaken ringformet basislegeme (78) med en fremre side hvorfra det rager ut en fleksibel ringleppe (80). Kuleventilelementet (34) har motsatte tetningsfremspring (72) som har kontakt med og avbøy er leppene (80) på pakningene (74) når kuleventilelementet (34) er i den lukkede stillingen.
