Abstract

En undergrunns sikkerhetsventil omfatter et rørformet legeme som er tilpasset til plassering inne i en brønnboring, og som avgrenser en fluidpassasje. Et ventilstengeorgan, så som en klaffventil, bæres av det rørformede legeme og er bevegelig gjennom en stengebane mellom posisjoner hvor det åpner og stenger fluidpassasjen. En aktuator, så som en forbelastningsfjær, presser ventilstengeorganet til sin stengeposisjon. Et strømningsrør er aksialt bevegelig inne i det rørformede legeme mellom en første posisjon hvor det hindrer aktuatoren i å presse ventilstengeorganet til sin stengeposisjon og en annen posisjon hvor det tillater aktuatoren å presse ventilstengeorganet til sin stengeposisjon. En låssammenstilling er tilveiebrakt for å hindre bevegelse av ventilstengeorganet fra sin åpneposisjon til sin stengeposisjon inntil strømningsrøret har blitt presset klar av stengebanen. Aspekter av sikkerhetsventilen anvendes av en relatert fremgangsmåte og et relatert system.
