Abstract

Ventilsammenstilling (100) omfattende et ventillegeme (110) med en fluidstrøm- ningspassasje (112-114) i kommunikasjon med ventillegemehulrommet (116) i hvilket er anbrakt en strømningsstyringsdel (118) for selektivt å lukke eller åpne fluidstrømningspassasjen. En ventiloperator (150) aktuerer en spindel (120) for- bundet til strømningsstyringsdelen ved en forbindelsesinnretning som tillater aksi- ell bevegelse av spindelen (120), men vesentlig ingen roterende bevegelse mel- lom spindelen (120) og strømningsstyringsdelen (118). Strømningsstyringsdelen (118) omfatterstoppinnretning (130) fora holde tilbake aksiell bevegelse av spin- delen (120) mot strømningsstyringsdelen (118) for å overføre spindelkraften til strømningsstyringsdelen (118) for på den måten å tilveiebringe en bedre tet- ningsfunksjon i den valgte ventilposisjonen. En spindelbevegende innretning (152) forbundet med ventiloperatoren og spindelen bevirker at spindelen (120) roterer og resiproserer. Ventiloperatoren (150) beveges selektivt strømningsstyringsdelen (118) til en lukket strømningsposisjon eller til en åpen strømningsposisjon.Valve assembly (100) comprising a valve body (110) having a fluid flow passage (112-114) in communication with the valve body cavity (116) into which is provided a flow control portion (118) for selectively closing or opening the fluid flow passage. A valve operator (150) actuates a spindle (120) connected to the flow control part by a connector which allows for axial movement of the spindle (120), but substantially no rotary movement between the spindle (120) and the flow control part (118). The flow control part (118) comprises stop means (130) forums to prevent axial movement of the spin part (120) towards the flow control part (118) to transfer the spindle force to the flow control part (118) in order to provide a better sealing function in the selected valve position. A spindle-moving device (152) connected to the valve operator and the spindle causes the spindle (120) to rotate and reciprocate. The valve operator (150) selectively moves the flow control portion (118) to a closed flow position or to an open flow position.
