Abstract

En sikkerhetsventil med en klaff/strømningsrørfriksjonsreduserer. En sikkerhetsventil for bruk i en underjordisk brønn innbefatter en lukkesammenstilling, et betjeningsorgan som går i inngrep med lukkesammenstillingen, og hvor minst en av lukkesammenstillingen og betjeningsorganet inkluderer en friksjonsreduserende innretning som skaffer rullende kontakt mellom lukkesammenstillingen og betjeningsorganet. En annen sikkerhetsventil innbefatter en klaff som roterer om et dreiepunkt i forhold til et sete, et strømningsrør som går i inngrep med klaffen for å dreie klaffen, og en friksjonsreduserende innretning som med rullende kontakt skaffer en forspenning av strømningsrøret mot dreiepunktet når strømningsrøret går i inngrep med klaffen. En ytterligere sikkerhetsventil beskrives i hvilken minst en av klaffen, setet og strømningsrøret har en friksjonsreduserende innretning tilfestet seg som skaffer rullende kontakt mellom klaffen og strømningsrøret.
