Anordning ved luftrOr til tanker.Device at air pipes for tanks.

Nærværende oppfinnelse angår en anordning ved luftror til tanker og andre oppbevaringsroll» og som rager inn i og overdekkes av en hette som er forsynt med en sentral soyle utformet til å samvirke med et i luftroret opplagret lagringsorgan, og som er innstillbar fra en i alt vesentlig stengt til åpen stilling ved at sbylen er flyttbar aksialt i forhold til lagringsorganet og er låsbar mot denne forflytting i åpen stilling. - The present invention relates to a device at the rudder for tanks and other storage roles" and which protrudes into and is covered by a cap which is provided with a central column designed to cooperate with a storage device stored in the rudder, and which is adjustable from a substantially closed to the open position in that the spool is movable axially in relation to the storage member and is lockable against this movement in the open position. -

Ved luftror til fartoystanker, jå som bunntanker, ballasttanker, brenselstanker og liknende foreligger et hovedkrav at ventileringen av respektive tank kan foregå uten at regn eller sjSvann (overbrytende sjoer) trenger ned i samme. For å fylle disse krav har man utformet hetten til luftroret slik at den manuelt kan senkes ned mot et sete (flens) og dermed tette mot inntrengende vann. Et mindre hull i hettens side sorger da for den nodvendige gjennom lastens bevegelse forårsakete luft-trykkutjevning. In the case of rudders for vessel tanks, as well as bottom tanks, ballast tanks, fuel tanks and the like, there is a main requirement that the ventilation of the respective tank can take place without rain or seawater (interrupting seas) penetrating into it. To meet these requirements, the hood of the air rudder has been designed so that it can be manually lowered against a seat (flange) and thus sealed against penetrating water. A smaller hole in the side of the cap then ensures the necessary air pressure equalization caused by the movement of the load.

Ved tidligere kjente konstruksjoner av denne art har man utformet hetten med en styrering, som tres over luftroret og som i åpen stilling hviler på et antall stotteknaster, mens disse stotteknaster i stengt stilling opptas av i styreringen anordnete spor. For å forhindre at hetten loftes av roret fins spesielle sikringsorganer. Denne konstruksjon er fremstillingsteknisk altfor komplisert og betinger av denne grunn en relativt hoy pris. In previously known constructions of this kind, the cap has been designed with a guide ring, which is threaded over the air rudder and which in the open position rests on a number of support cams, while in the closed position these support cams are occupied by grooves arranged in the guide ring. To prevent the hood from lifting off the rudder, there are special safety devices. This construction is far too complicated in terms of manufacturing technology and for this reason requires a relatively high price.

Hensikten med oppfinnelsen er å eliminere de ovenfor nevnte ulemper, og oppfinnelsen er i hovedsakenkarakterisert vedat soylen er forsynt med en radialt rettet styrestift med storre fri lengde enn spillerommet mellom soyle og lagringsorgan og anordnet på det sted av soylen som ligger ved lagringsorganet, samt at lagringsorganet, som har form av en hylse, dels ved sin endeflate er forsynt med en etter styrestiften avpasset radial fordypning og dels på sin innside er forsynt med et aksialt spor i en fra fordypningen atskilt vinkelstilling, hvilket spor har tilstrekkelig dybde for innforing av styrestiften, hvorved låsning av hetten i åpen stilling skjer ved at hetten forst loftes slik at styrestiften rekker ovenfor lagringsorganet s nevnte endeflate, hvoretter hetten dreies og senkes slik at styrestiften kommer inn i fordypningen. The purpose of the invention is to eliminate the above-mentioned disadvantages, and the invention is mainly characterized by the fact that the soil is provided with a radially directed guide pin with a greater free length than the clearance between the soil and the storage member and arranged at the place of the soil that is next to the storage member, and that the storage member , which has the shape of a sleeve, partly at its end surface is provided with a radial recess adapted to the guide pin and partly on its inside is provided with an axial groove in an angular position separate from the recess, which groove has sufficient depth for inserting the guide pin, whereby locking the cap in the open position takes place by first lifting the cap so that the guide pin reaches above the storage member's aforementioned end surface, after which the cap is turned and lowered so that the guide pin enters the recess.

Oppfinnelsen eksemplifiseres på vedfdy-ete tegning, der fig. 1 viser et lengdesnitt gjennom anordningen ifolge oppfinnelsen, med hetten i åpen stilling, fig»2 viser samme detalj med hetten i stengt stilling, fig. 3 er et riss ovenfra på luftroret uten hette og fig. 4 er et snitt etter lin-jen IV-IV i fig. 3. - The invention is exemplified in the accompanying drawing, where fig. 1 shows a longitudinal section through the device according to the invention, with the hood in the open position, fig. 2 shows the same detail with the hood in the closed position, fig. 3 is a top view of the air tube without a cap and fig. 4 is a section along the line IV-IV in fig. 3. -

Få tegningen betegner 1 overdelen avGet the drawing denotes 1 upper part of

et over dekk nående luftror for evakuering av en tank eller liknende. Luftroret avsluttes i sin 6vre ende av en dekkplate 2, som er festet til roret. Aksialt med dette og i dets sentrum er anordnet et lagringsorgan 3. I noen avstand fra rorets ovre ende er på dets utside festet en ringformet flens 4*Med 5jbetegnes en hette, som er således dimensjonert at den med klaring omgir luftroret. Til hettens innside er festet en sentralt anordnet soyle 6, som er forsynt med en styrestift 7 og nær sin frie ende med et stopporgan 8. an air rudder reaching above the deck for evacuating a tank or similar. The air rudder is terminated at its rear end by a cover plate 2, which is attached to the rudder. Axial to this and in its center is arranged a bearing member 3. At some distance from the upper end of the rudder, an annular flange 4 is attached to its outside. A centrally arranged column 6 is attached to the inside of the cap, which is provided with a guide pin 7 and close to its free end with a stop device 8.

Lagringsorganet 3 består av en utvendig gjenget og med hode forsynt bossing, som ved hjelp av en mutter 9 er festet til luftrdrets dekkplate. Bossingen er forsynt med en aksial boring 10, hvori er uttatt et langsgående aksialt spor 11. I noen avstand fra dette er en radial fordypning 12 utformet i den ovre flate av bdssingens hode. Nevnte flate har en avsats 13, som strekker seg fra sporet 11 til fordypningen 12. Dybden og bredden av sporet 11 og av fordypningen 12 er avpasset etter styrestiftens 7 dimensjon, som er den samme som stopporganets 8. 1 det viste utfdrelseseksempel utgjor det nedsenkte parti 18 ca. halve hoyden av bdssingens hode, men vilkårlig storrelse på partiet 18 og dermed avstanden mellom fordypning 12 og spor 11 kan naturligvis komme på tale. The storage member 3 consists of an externally threaded boss provided with a head, which is attached to the air rotor's cover plate by means of a nut 9. The bossing is provided with an axial bore 10, in which a longitudinal axial groove 11 is taken. At some distance from this, a radial depression 12 is formed in the upper surface of the head of the bossing. Said surface has a ledge 13, which extends from the groove 11 to the recess 12. The depth and width of the groove 11 and of the recess 12 are adjusted according to the dimension of the guide pin 7, which is the same as the stop member 8. 1 the shown example of extension forms the submerged part 18 approx. half the height of the bdssing's head, but arbitrary size of the part 18 and thus the distance between recess 12 and groove 11 can of course come into play.

Luftroret 1 er nær dekkplaten 2 forsynt med et antall åpninger 14, som hensiktsmessig dekkes av et som flammebeskyttelse utformet metallnett 15. Dette fikseres mot luftroret av en ovre og en nedre fastspenningsanordning 16.Hetten 5 er i sideveggen nær sin åpne kant forsynt med en mindre åpning 17, slik at det også når hetten befinner seg i stengt stilling kan skje en utjevning av trykk i tanken. - The air duct 1 is close to the cover plate 2 provided with a number of openings 14, which are conveniently covered by a metal net 15 designed as flame protection. This is fixed to the air duct by an upper and a lower clamping device 16. The hood 5 is provided in the side wall near its open edge with a smaller opening 17, so that pressure can equalize in the tank even when the cap is in the closed position. -

Anordningens virkemåte er f61gende: - The operation of the device is as follows: -

Hetten 5 anbringes over luftroret ved at soylen 6 fores ned i boringen 10 med stopporganet 8 rett overfor sporet 11, hvoretter hetten senkes ned så langt at styrestiften 7 kommer å hvile mot flaten 18 på bdssingens 3 hode. Gjennom dreining av hetten kan styrestiften deretter bringes til å senkes ned i fordypningen 12, i hvilken stilling hetten befinner seg i en avstand fra flensen 4, tillatende vesentlig maksimal ventilering av tanken. The cap 5 is placed over the air rudder by feeding the shaft 6 down into the bore 10 with the stop member 8 directly opposite the slot 11, after which the cap is lowered so far that the guide pin 7 comes to rest against the surface 18 on the head of the bdssing 3. By turning the cap, the guide pin can then be caused to be lowered into the recess 12, in which position the cap is at a distance from the flange 4, allowing substantially maximum ventilation of the tank.

Ved stengning av hetten ldftes stiftenWhen closing the cap, the pin is lifted

ut av fordypningen og hetten dreies ca. 180°, med styrestiften glidende på flaten 18. Når stiften slår mot ansatsen 13 befinner den seg i en sådan stilling at den kan gli ned i sporet 11.Hetten senkes derved mot flensen 4 (fig. 2) og tetter mot denne. Ventilering av tanken kan nå bare skje gjennom åpningen 17, som er plassert slik i forhold til åpningene 14 i roret at det fordres at åpningen 17 en lengre tid står under vann for at dette skal trenge opp og til åpningene 14. out of the recess and the cap is turned approx. 180°, with the guide pin sliding on the surface 18. When the pin hits the stop 13, it is in such a position that it can slide down into the groove 11. The cap is thereby lowered towards the flange 4 (fig. 2) and seals against it. Ventilation of the tank can now only take place through the opening 17, which is placed in such a way in relation to the openings 14 in the rudder that it is required that the opening 17 is under water for a long time in order for this to penetrate up and to the openings 14.

Ved at stopporganet 8 er anordnet ca. 90° forskjdvet i forhold til styrestiften 7 kan hetten bare fjernes fra sine to stillinger ved at den dreies en kvart omdreining, så at stopporganet kommer rett overfor sporet 11. Gjennom dette arrangement er hetten sikret mot utilsiktet fjernelse f.eks. By the fact that the stop member 8 is arranged approx. 90° offset in relation to the guide pin 7, the cap can only be removed from its two positions by turning it a quarter of a turn, so that the stop member comes directly opposite the groove 11. Through this arrangement, the cap is secured against accidental removal, e.g.

ved overbrytende sjoer.in case of breaking seas.

For i mest mulig utstrekning å forhindre rustangrep er det på lagringsorganets 3 yttergjenger skrudd en med bunn forsynt smorehylse 19, som omgir den del av soylen 6 som ligger innenfor luftroret. Smorehylsen kan inneholde enten fett eller olje. - In order to prevent rusting as much as possible, a grease sleeve 19 provided with a bottom is screwed onto the outer threads of the bearing member 3, which surrounds the part of the soil 6 that lies inside the air rudder. The butter sleeve can contain either fat or oil. -
