Description

Oppfinnelsen vedrører en anordning ved tvillingtanker for trykkutjevning i gassfasen. Gasskip med trykktanker har mange fordeler, og så godt som alle mindre skip er utstyrt med slike tanker, Utviklingen går i den retning at man mer og mer benytter såkalte tvillingtanker, som gir en bedre utnyttelse ay skroget enn enkle sylindriske tanker. Tvillingtanker må av åpenbare styrkehensyn ha et plant skott i lengderetningen. Dette skottet kan ikke dimensjoneres for et differensialtrykk som til-svarer det trykk tanken som sådan dimensjoneres for, fordi skottet ikke kan betraktes som en av et indre trykk påvirket membran. Man vil derfor ved bruk av tvillingtanker være avhengig av å ha en eller annen form for trykkutjevning mellom de to tankene, som kan ha samme last eller to forskjellige kompatible laster. The invention relates to a device for twin tanks for pressure equalization in the gas phase. Gas ships with pressure tanks have many advantages, and almost all smaller ships are equipped with such tanks. Development is moving in the direction of more and more using so-called twin tanks, which provide better utilization of the hull than simple cylindrical tanks. For obvious reasons of strength, twin tanks must have a flat bulkhead in the longitudinal direction. This bulkhead cannot be designed for a differential pressure that corresponds to the pressure the tank is designed for, because the bulkhead cannot be considered a membrane affected by an internal pressure. When using twin tanks, one will therefore be dependent on having some form of pressure equalization between the two tanks, which may have the same load or two different compatible loads.

Hver tank utstyres vanligvis med en eller flere domer, og en nærliggende løsning er å forbinde disse med hverandre ved hjelp av et utvendig rør. Et slikt utvendig rør, som i og for seg er en integrert del av tanken, vil imidlertid repre-sentere en alvorlig obstruksjon ombord i skip, samtidig som det er lett utsatt for skader, og dermed representerer et sikkerhets-problem, Each tank is usually equipped with one or more domes, and a nearby solution is to connect these to each other by means of an external pipe. Such an external pipe, which in and of itself is an integral part of the tank, will however represent a serious obstruction on board a ship, at the same time that it is easily susceptible to damage, and thus represents a safety problem,

En annen nærliggende løsning vil være å innstallere et innvendig U-formet rør. Ved slike U-formede rør får man imidlertid problemer med væskeansamlinger hvor røret ligger lavest. Another nearby solution would be to install an internal U-shaped pipe. With such U-shaped pipes, however, problems arise with liquid accumulations where the pipe is lowest.

Oppfinnelsen tar sikte på å tilveiebringe en trykk-ut jevningsanordning som ikke er beheftet med de foran nevnte problemer, og dette oppnår man ved at det sørges for egnede innven-dige rørforbindelser mellom tankene uten mulighet for væskeansamlinger i rørforbindelsene. The invention aims to provide a pressure equalization device which is not affected by the aforementioned problems, and this is achieved by providing suitable internal pipe connections between the tanks without the possibility of liquid accumulation in the pipe connections.

Ifølge oppfinnelsen er det derfor tilveiebragt en anordning ved tvillingtanker for trykkutjevning i gassfasen, hvil-ken anordning er kjennetegnet ved en innvendig rørforbindelse fra hver tank til den andre, fra et første punkt over den ene tankens fyllingsnivå og til et andre punkt under den andre tankens fy 11-ingsnivå. According to the invention, a device is therefore provided for twin tanks for pressure equalization in the gas phase, which device is characterized by an internal pipe connection from each tank to the other, from a first point above the filling level of one tank and to a second point below that of the other tank fy 11-ing level.

Ved hjelp" av en slik anordning vil man unngå problemer med væskeansamlinger, fordi man unngår bruk av U-formede rør. Samtidig bibeholder man den fordel som ligger i at rørfor-bindelsene er anbragt inne i tankene og derfor er godt beskyttet mot ytre påkjenninger. Det første punkts avstand over fyllingsnivået i tanken bestemmes for hver enkelt konstruksjon, idet denne avstand jo må være større enn den høyde som væsken vil stige opp til i rørforbindelsene under påvirkning av et overtrykk i den andre tanken. Hersker det et overtrykk i den ene tanken vil væske trykkes opp i den ene rørforbindelse som går ut fra denne tank, samtidig som væskenivået vil synke under fyllingsnivået i den andre rørforbindelsen. Er trykkdifferensen tilstrekkelig stor vil gassen til slutt boble over fra den ene til den andre tank, uten at det flyter væske over. With the help of such a device, you will avoid problems with liquid accumulations, because you avoid the use of U-shaped pipes. At the same time, you retain the advantage that lies in the fact that the pipe connections are located inside the tanks and are therefore well protected against external stresses. The distance of the first point above the filling level in the tank is determined for each individual construction, as this distance must be greater than the height to which the liquid will rise in the pipe connections under the influence of an overpressure in the other tank. Is there an overpressure in one tank liquid will be pushed up in one pipe connection that goes out from this tank, at the same time the liquid level will drop below the filling level in the other pipe connection. If the pressure difference is large enough, the gas will eventually bubble over from one tank to the other tank, without liquid flowing above.

Hensiktsmessig utnytter man de domer som forelig-ger på tankene, idet det nevnte første punkts anordnes i en respek-tiv dom. Appropriate use is made of the judgments that are available on the tanks, as the aforementioned first point is arranged in a respective judgment.

Ved kraftig rulling av skipet, eller sterk slagside vil man i de tilfeller hvor tanken er montert langskips få et spe-sielt problem. Væskespeilet i en tank vil da nemlig kunne ligge høyere enn toppen av rørforbindelsen i den andre, og væske vil da kunne strømme over. Av denne grunn er det hensiktsmessig å anordne en flottørventil i hver rørforbindelse i eller nær det nevnte første punkt. Hensiktsmessig kan flottørventilen være en kule i et rør. Når man monterer en slik ventil i toppen av hvert av de to forbindelsesrørene vil det ved en tendens for væsken til å strømme ut oppnås en lukking av rørforbindelsen. In the case of strong rolling of the ship, or a strong list, in cases where the tank is mounted longboard, you will have a special problem. The liquid level in one tank will then be able to be higher than the top of the pipe connection in the other, and liquid will then be able to flow over. For this reason, it is appropriate to arrange a float valve in each pipe connection in or near the aforementioned first point. Conveniently, the float valve can be a ball in a tube. When such a valve is installed at the top of each of the two connecting pipes, a tendency for the liquid to flow out will result in a closure of the pipe connection.

Oppfinnelsen skal forklares nærmere under henvis-ning til tegningene som viser et utførelseseksempel. Fig. 1 viser et snitt gjennom et skip med en tvillingtank. Fig. 2 viser et.snitt av en tvillingtank rent skjematisk, i likevektstilstand, Fig. 3 viser et skjematisk snitt som i fig. 2, med ulike gasstrykk i de to tanker, og Fig. 4 viser rent skjematisk en mulig flottørut-førelse. The invention will be explained in more detail with reference to the drawings which show an exemplary embodiment. Fig. 1 shows a section through a ship with a twin tank. Fig. 2 shows a purely schematic section of a twin tank, in a state of equilibrium, Fig. 3 shows a schematic section as in fig. 2, with different gas pressures in the two tanks, and Fig. 4 schematically shows a possible float design.

I fig. 1 er det vist et snitt gjennom et vanlig gasskip med trykktank utformet som tvillingtank. I skipsskroget 1 er det montert en tvillingtank 2. Tvillingtanken består av to tanker 3 og 4 som er atskilt fra hverandre med et langsgående skott 5. Hver tank har en dom 6 henholdsvis 7. Forøvrig er den rent konstruktive oppbygging og det nødvendige utstyr velkjent og krever derfor ingen nærmere beskrivelse her. Fig. 2 viser tvillingtanken 2 med en trykkutjevningsanordning ifølge oppfinnelsen. Trykkutjevningsanordningen består av et i begge ender åpent rør 8 som strekker seg i fra domen 6 og ned og inn i den andre tank 4, til et punkt under fyllingsnivået som i figuren er betegnet med uttrykket 98%, hvilket betegner et vanlig fyllingsnivå. Et i begge ender åpent rør 9 strekker seg på lignende måte fra domen 7 og inn i.den hosliggende tank 3. Gasstrykkene i de to tanker 3 og 4 er i fig. 2 betegnet med henholdsvis og P^In fig. 1 shows a section through a normal gas ship with a pressure tank designed as a twin tank. A twin tank 2 is mounted in the ship's hull 1. The twin tank consists of two tanks 3 and 4 which are separated from each other by a longitudinal bulkhead 5. Each tank has a dom 6 and 7 respectively. Otherwise, the purely constructive structure and the necessary equipment are well known and therefore requires no further description here. Fig. 2 shows the twin tank 2 with a pressure equalization device according to the invention. The pressure equalization device consists of a pipe 8 open at both ends which extends from the dome 6 down and into the second tank 4, to a point below the filling level which is denoted in the figure with the expression 98%, which denotes a normal filling level. A pipe 9 open at both ends extends in a similar way from the dome 7 into the adjacent tank 3. The gas pressures in the two tanks 3 and 4 are in fig. 2 denoted respectively by and P^

og man ser av fig. 2 at disse to trykk er like store. and you can see from fig. 2 that these two pressures are equal.

Annerledes er forholdene i fig. 3, som viser de samme tanker, men med trykket P^ tenkt større enn trykket P^. The conditions in fig. 3, which shows the same tanks, but with the pressure P^ thought greater than the pressure P^.

Ved en slik trykkforskjell vil f.eks. væsken i tanken 4 trenge inn i røret 8 og opp til et nivå i dette som er betegnet med den øverste dobbeltpil c. Likeledes vil den væske som befinner seg i røret 9 trykkes ned i dette, til et nivå som nå er betegnet med den nederste dobbeltpil b i fig. 3. Så snart trykkforskjellen øker utover en viss verdi vil nivået i røret 9 synke så langt at gass kan boble ut som antydet med boblene 10, og dette skjer uten at det flyter væske over. In the event of such a pressure difference, e.g. the liquid in the tank 4 penetrates into the pipe 8 and up to a level in it which is denoted by the upper double arrow c. Likewise, the liquid which is in the pipe 9 will be pressed down into it, to a level which is now denoted by the lower double arrow b in fig. 3. As soon as the pressure difference increases beyond a certain value, the level in the tube 9 will drop so far that gas can bubble out as indicated by the bubbles 10, and this happens without liquid flowing over.

Høyden a, det vil si avstanden fra fyllingsnivået og til de to rørs øverste åpne ender må naturligvis bestemmes ut ifra den spesifikke vekt til lasten, slik at man er sikret at a er større enn b. Er det samme last i de to tanker, vil nivået b være lik nivået c. The height a, i.e. the distance from the filling level and to the top open ends of the two pipes must of course be determined based on the specific weight of the load, so that it is ensured that a is greater than b. If there is the same load in the two tanks, the level b be equal to the level c.

For å hindre væskeoverstrømning ved kraftig rulling eller sterk slagside, som vil kunne medføre at væskespeilet i en tank vil kunne bli liggende høyere enn toppen av røret i den andre tanken, hvorved væske ville kunne strømme over, er det i hvert rør 8, 9 anordnet en enkel flottørventil i toppen av hvert av de to rørene. Denne flottørventil er i fig. 2 og 3 betegnet med 11 henholdsvis 12. Fig. 4 viser mer detaljert hvorden denne enkle flottørventil kan se ut. Røret 8 er utvidet med et parti 13 og inn i dette utvidede parti ligger en kule, f.eks. av teflon, med indre hulrom, eller av et annet bestandig og egnet materiale. Kulen 11 hviler i dette tilfelle på en rist 14 og vil når væske strømmer opp i røret 8 flyte opp på væsken og stenge mot det innsnevrede parti 15 i rørets 8 øvre ende. Konstruksjonen av flottørventilen er således slik at den kun hindrer væske, ikke gass. In order to prevent liquid overflow in the event of strong rolling or strong impact, which could result in the liquid mirror in one tank being higher than the top of the pipe in the other tank, whereby liquid could flow over, in each pipe 8, 9 are arranged a simple float valve at the top of each of the two pipes. This float valve is in fig. 2 and 3 denoted by 11 and 12 respectively. Fig. 4 shows in more detail what this simple float valve can look like. The tube 8 is extended with a part 13 and into this extended part lies a ball, e.g. of Teflon, with an internal cavity, or of another durable and suitable material. In this case, the ball 11 rests on a grate 14 and will, when liquid flows up into the pipe 8, float up onto the liquid and close against the narrowed part 15 at the upper end of the pipe 8. The construction of the float valve is thus such that it only prevents liquid, not gas.
