Abstract
En ventil (10) for skittent fluid for å forsegle høye fluiddifferensialtrykk i et boremiljø, og fremgangsmåter for å bruke en slik ventil (10) er beskrevet. En utførelsesform · av ventilen (10) innbefatter en pakningsinnsats (20) med flere åpninger (14, 16) for å dirigere en fluidbane gjennom innsatsen (20), en fjær (30) forbundet ved én ende til pakningsinnsatsen (20) og som strekker seg gjennom fluidbanen, og et pakningsorgan (24) forbundet med den andre enden av fjæren (30). Pakningen (24) kan drives mellom en åpen stilling og en lukket stilling slik at den dekker én av åpningene (14, 16) i pakningsinnsatsen (20) når den er i den lukkede stilling, for derved å tette fluidstrømningen gjennom fluidbanen til pakningsinnsatsen (20). Fjæren (30) tilveiebringer en forbelastningskraft på pakningsorganet (24) slik at pakningsorganet (24) alltid har tilstrekkelig kontakt med overflatene som omgir den åpningen (14, 16) som pakningen (24) dekker.
