Abstract

Søknaden viser en ventil (100) som kan omfatte enten en sikringsventil eller en stormbølge-strupeventil eller lignende, fior å isolere en sone (108) under en ventil (100) fira en produksjonsrørstreng (102). Ventilen (100) iimbefiatter fiortriimsvis en strømningsavbrytnings- overfiateenhet, så som en klafFv^entil eller en kuleventil, som fiorskyves ved hjelp av en betjeningsledning (130) som strekker seg fira et overfiatested til ventilen (100) gjennom produksjonsrørstrengens (102) innside. Søknaden viser også en omløpsledning (140) innvendig i produksjonsrørstrengen (102) som tillater kommunikasjon fra overflatestedet til produksjonssonen (112) når ventilen (100) er i enten en åpen eller en lukket stilling.
