Stengeventil

Stengeventil med eksentrisk opplagret ventilskive (5) og minst en gummielastisk tetningsring (1), og kjennetegnet ved at det i et ringformet spor (2) i ventilhuset (3) er innmontert i en tetningsring (1) i anlegg mot ventilsetet (6) innenfor ventilskivens (5) svingebue (4) og at det mellom sporet (2) og ventilsetet (6) er anordnet kileringformede hulrom (7,8) foran og bak tetningsringen (fig. 1). The stop valve has an eccentrically-mounted valve disc (5) and at least one sealing ring (1). The sealing ring, in the form of an O ring, is mounted in an annular groove (2) in the housing (3) and rests against the valve seating (6) within the pivot radius (4) of the valve disc. Between the groove and the valve seating in front of and after the sealing ring are tapered ring spaces (7, 8) filled with rubbery elastic filler (13). The groove is defined by a ring (10) held inside a groove (11). The sealing ring has a wire ring as reinforcement core (12).
