Abstract

Fremgangsmåte og anordning for samtidig testing på bruksstedet av trykkintegriteten til et ventilhus (12) og tetteevnen til metalliske tetteflater mot huset (12) og mot en sluse (24) ved åpen og stengt ventil, f.eks. en sluseventil. Et testemedium som er satt under trykk eksternt tilføres ventilhulrommet (16) gjennom en eksisterende åpning som normalt ikke benyttes for trykkprøvningt slik som en dreneringskobling på lokket eller koblinger for spyling og tilførsel av fett i ventilhuset (12). Anordningen omfatter et ventilsete (43) som har en basisdel (49) og en hylse (50) som er i teleskopisk forbindelse enten på ventilens oppstrøms side eller på begge sider.Method and apparatus for simultaneous testing at the point of use of the pressure integrity of a valve housing (12) and the sealing ability of metallic sealing surfaces against the housing (12) and against a lock (24) by open and closed valves, e.g. a locking valve. An externally pressurized test medium is supplied to the valve cavity (16) through an existing opening which is not normally used for pressure testing such as a drainage connection on the lid or connections for flushing and feeding grease into the valve body (12). The device comprises a valve seat (43) having a base portion (49) and a sleeve (50) which are in telescopic connection either on the upstream side of the valve or on both sides.
