Abstract

Denne utførelsesform omfatter et ventilstempel (14) anbragt på en stang (16) soa er glldbart lagret 1 en åpning (18) 1 det nedre hus (20) av boreslkrlngs- ventllen (10). Ventllsteapelet (14) og stangen (16) stikker Inn 1 den sentrale boring 1 boreslkrlngs- ventllen (10) når det er fart til åpen stilling av eo hydraulisk betjenlngsanordnlng (22). Når ventll- steapelet (14) og stangen (16) er 1 åpen stilling, kan brønnboringens gasser koaae Inn 1 det ringformede roa aelloa stangen (16) og åpningen (18) gjennoa det nedre hus (20) av boreslkrlngsventllen (10). Brannborlngs- gassene blir da luftet fra åpningen (18) gjennoa en åpen luftepassasje til utsiden av boreslkrlngsventllen. Den hydrauliske betjenlngsanordnlng (22) er fjxrforspendt for å holde ventllsteapelet (14) og stangen (16) 1 lukkestllllng til enhver tid når den hydrauliske betjenlngsanordnlng (22) Ikke er 1 virksomhet. Ventllsteapelet vil derfor automatisk lukke når som helst aan er uten hydraulisk styring. Under normal drift vil den hydrauliske betjenlngs- anordnlng (22) holde ventllsteapelet (14) og stangen (16) 1 åpen stilling Inntil brønnboringens gasser er luftet ut. Når utluftingen er fullført, vil den hydrauliske betjenlngsanordnlng (22) trekke ventll- steapelet (14) og stangen (16) tilbake til lukkestilling.
