Description
For å oppnå en god tetning mellom en beholder og et på denne anordnet lokk er det vanlig å planbearbeide beholderens øvre kant og anbringe en pakning mellom denne kant og lokket. I stedet for å anvende en plan pakning, anordnes der under tiden et spor i den nevnte kant, i hvilken der anbringes en tetnings-list som trykkes sammen og tetter mellom beholderen og lokket når et antall spennbolter trekkes til. In order to achieve a good seal between a container and a lid arranged on it, it is common to plane the upper edge of the container and place a gasket between this edge and the lid. Instead of using a flat gasket, a groove is meanwhile arranged in the said edge, in which a sealing strip is placed which is pressed together and seals between the container and the lid when a number of tension bolts are tightened.
Ved store enheter, såsom transformatorbeholdere, blir bearbeidelsen av beholderens øvre kant kostbar, hvilket dels skyldes at beholderens omkrets er stor og dels at materialet i beholderens vegger har en betydelig tykkelse ved store enheter. In the case of large units, such as transformer containers, the processing of the container's upper edge becomes expensive, which is partly due to the container's circumference being large and partly to the fact that the material in the container's walls has a significant thickness in large units.
Foreliggende oppfinnelse angår en anordning for tetning mellom en beholder og et på denne anordnet lokk, idet der på beholderens utside og i noen avstand fra denne øvre kant er festet en rundt beholderen forløpende rammeflens, og hvor lokket rager et stykke utenfor beholderens utside, således at lokkets ytterkontur er i hovedsaken lik flensens ytterkontur, og hvor lokket kan festes til flensen ved hjelp av et antall bolter gjennom lokket og flensen, og hvor der i det spor som dannes mellom flensens og den utenfor beholderen utragertde del av lokket dels er anordnet en pakning av plastisk materiale nærmest beholderen og dels en utenfor pakningen liggende fjærende støttelist. The present invention relates to a device for sealing between a container and a lid arranged on it, where a frame flange running around the container is fixed on the outside of the container and at some distance from this upper edge, and where the lid projects a bit outside the outside of the container, so that the outer contour of the lid is essentially the same as the outer contour of the flange, and where the lid can be attached to the flange using a number of bolts through the lid and the flange, and where in the groove formed between the flange and the part of the lid protruding outside the container, a gasket is partly arranged of plastic material closest to the container and partly a springy support strip lying outside the packing.
Hensikten med oppfinnelsen er å tilveiebringe en anordning av den ovenfor nevnte art, ved hvilken det ikke er nød-vendig å foreta en bearbeidelse av beholderens øvre kant, og det særegne ved oppfinnelsen er at pakningen er i kontakt med beholderens yttervegg og at støttelisten med en kant ligger an mot pakningen og med en motsatt kant hviler mot boltene og derved danner en fjærende støtte som ligger mellom boltene og stadig holder pakningen trykket mot beholderen. The purpose of the invention is to provide a device of the type mentioned above, in which it is not necessary to process the upper edge of the container, and the peculiarity of the invention is that the gasket is in contact with the outer wall of the container and that the support strip with a edge rests against the gasket and with an opposite edge rests against the bolts and thereby forms a springy support which lies between the bolts and constantly keeps the gasket pressed against the container.
' Hensiktsmessig er støttelistens høyde noe mindre enn avstanden mellom flensen og lokket. ' Appropriately, the height of the support strip is somewhat less than the distance between the flange and the lid.
Tegningen viser ét snitt av et øvre hjørne av en trans-formatorbeholder med en tetning ifølge oppfinnelsen. The drawing shows a section of an upper corner of a transformer container with a seal according to the invention.
Transformatorbeholderens vegg er betegnet med 1 og dens lokk med 2. Dette rager et stykke utenfor beholderveggen, på hvilken vegg og i noen avstand fra dens øvre kant der er festet en rundt beholderen gående ramme 3, gjennom hvilken og den utenfor beholderen liggende del av lokket der er boret et antall hull 4 som er jevnt fordelt rundt beholderens omkrets. Gjennom hul-lene 4 er der ført bolter 5 med hver sin mutter 6. I sporet mellom beholderveggen, lokket og rammen ligger en pakning 7 av plastisk materiale, mellom hvilken og rekken av bolter 5 der er inn-lagt en fjærende støttelist 8, således at dennes på tegningen sett venstre kant ligger an mot pakningen, mens den høyre kant ligger an mot boltene. The wall of the transformer container is denoted by 1 and its lid by 2. This protrudes some distance outside the container wall, on which wall and at some distance from its upper edge there is attached a frame 3 going around the container, through which and the part of the lid lying outside the container a number of holes 4 are drilled there which are evenly distributed around the circumference of the container. Through the holes 4 there are bolts 5 each with a nut 6. In the groove between the container wall, the lid and the frame is a gasket 7 made of plastic material, between which and the row of bolts 5 there is inserted a springy support strip 8, thus that its left edge as seen in the drawing lies against the gasket, while the right edge lies against the bolts.
Pakningens 7 høyde er således valgt at den godt fyller ut sporet mellom lokket og rammen, mens støttelistens høyde er noe mindre. Når mutrene 6 trekkes til, vil rammen og den utragende del av lokket bli presset mot hinannen således at pakningen 7 vil bli deformert og fylle eventuelle hulrom mellom baholder-veggens øvre kant og lokket og også trenger inn i spaltene mellom rammen og støttelisten og mellom denne og lokket. Da støt-telisten er fjærender vil den ved økende sammentrekning mellom lokk og ramme bli presset mer eller mindre ut mellom boltene. Dette medfører at pakningen kontinuerlig holdes under et visst trykk, hvilket medfører at tetningen mellom beholderveggen og lokket opprettholdes, selv om pakningens volum endres noe som følge av temperaturvariasjoner. The height of the gasket 7 has been chosen so that it fills the slot between the lid and the frame well, while the height of the support strip is somewhat smaller. When the nuts 6 are tightened, the frame and the protruding part of the lid will be pressed against each other so that the gasket 7 will be deformed and fill any voids between the upper edge of the baholder wall and the lid and also penetrate into the gaps between the frame and the support strip and between this and the lid. As the support strip is spring-ended, it will be more or less pushed out between the bolts by increasing contraction between the lid and frame. This means that the seal is continuously kept under a certain pressure, which means that the seal between the container wall and the lid is maintained, even if the seal's volume changes somewhat as a result of temperature variations.
Oppfinnelsen medfører også at man på enkel måte kan bearbeide beholderens øvre kant, således at den blir tilnærmel-sesvis slett. Rammen 3 festes hensiktsmessig til beholderen ved sveising med sin øvre kant i en viss avstand fra beholderveggens 1 øvre kant før denne bearbeides, hvilken avstand er minst like stor som den endelige avstand mellom rammen og lokket skal være. Beholderens øvre kant skjæres derpå til riktig mål ved hjelp av en på rammens 3 overside forskyvbar skjærebrenner. Avstanden mellom rammens overside og lokkets underside blir da veldefinert når lokket legges på plass. For å oppnå en fullgod tetning bør pakningens 7 tverrsnittsareal overskride det for pakningen be-stemte areal av sporet mellom veggen 1, lokket 2, rammen 3 og støttelisten 8 med ca. 20 %. Da finnes der tilstrekkelig over-skuddsvolum av pakningen til at den ved boltenes tiltrekning vil fylle ut hulrom i sporets kanter og presse støttelisten ut mellom boltane, således at der alltid oppnås et tilstrekkelig trykk fra støttelisten mot pakningen. The invention also means that the upper edge of the container can be processed in a simple way, so that it becomes approximately smooth. The frame 3 is suitably attached to the container by welding with its upper edge at a certain distance from the upper edge of the container wall 1 before this is processed, which distance is at least as large as the final distance between the frame and the lid should be. The upper edge of the container is then cut to the correct size using a cutting torch that can be moved on the upper side of the frame 3. The distance between the upper side of the frame and the lower side of the lid is then well defined when the lid is placed in place. In order to achieve a fully satisfactory seal, the cross-sectional area of the gasket 7 should exceed the area determined for the gasket of the groove between the wall 1, the lid 2, the frame 3 and the support strip 8 by approx. 20%. There is then sufficient excess volume of the gasket so that when the bolts are tightened, it will fill in cavities in the edges of the track and push the support strip out between the bolts, so that sufficient pressure is always achieved from the support strip against the gasket.
