Description

Oppfinnelsen vedrører en trykkutligning for oppdriftssekker i vann, som angitt i innled-ningen til patentkrav 1. The invention relates to a pressure equalization for buoyancy bags in water, as stated in the introduction to patent claim 1.

Oppfinnelsen utgår fra BE 470.543 A. Det er her kjent en énveisventil for bruk i elastiske beholdere, omfattende en elastisk tut med en elastisk lukkedel, og en flens for forbindelse med den elastiske beholderen. Det beskrives en ventil for et legeme for trykkutlik-ning. Ventilen består som nevnt av en elastisk tut og en flens for forbindelse med trykk-utligningslegemet. Tuten forløper i tetningen med parallelt motstående flater. For å overvinne disse flatenes sperrevirkning er det nødvendig med et forholdsmessig større trykk, da i tillegg de parallelle tetteflatene forsterkes ved et ringformet materialtverrsnitt. The invention is based on BE 470.543 A. A one-way valve for use in elastic containers is known here, comprising an elastic spout with an elastic closing part, and a flange for connection with the elastic container. A valve for a body for pressure equalization is described. As mentioned, the valve consists of an elastic spout and a flange for connection with the pressure equalization body. The spout extends into the seal with parallel opposite surfaces. In order to overcome the blocking effect of these surfaces, a proportionately greater pressure is required, as in addition the parallel sealing surfaces are reinforced by an annular material cross-section.

Hensikten med oppfinnelsen er å tilveiebringe en enkel og virksom overtrykkutligning for oppdriftssekker, som er helt omgitt av vann, allerede for små trykkforskjeller fra om lag 0,1 bar. The purpose of the invention is to provide a simple and effective overpressure equalization for buoyancy bags, which are completely surrounded by water, already for small pressure differences from about 0.1 bar.

Den foreliggende oppfinnelsen løser hensikten ved å fremby en trykkutligningsanordning for legemer i vann, hvor ventiler i veggen åpens automatisk ved overtrykk, hvorved den enkelte ventil består av en elastisk tut, hvis innløp kan bringes i forbindelse med volumet i legemet, og hvis utløp kan bringes i forbindelse med legemets omgivelsesmedium, og hvor utløpet er lukket med en elastisk lukkedel og tuten mot legemet har en med legemet forbundet flens. Anordningen ifølge oppfinnelsen kjennetegnes ved at en konusholder av et fastere materiale, som er forbindbar med legemets innervegg og med flensen i tuten. Foretrukne trekk ved anordningen ifølge oppfinnelsen fremgår av de medfølgende krav 2 til 8. The present invention solves the purpose by offering a pressure equalization device for bodies in water, where valves in the wall are opened automatically in case of overpressure, whereby the individual valve consists of an elastic spout, the inlet of which can be brought into connection with the volume in the body, and the outlet of which can be brought in connection with the body's surrounding medium, and where the outlet is closed with an elastic closure part and the spout towards the body has a flange connected to the body. The device according to the invention is characterized by a cone holder made of a firmer material, which can be connected to the inner wall of the body and to the flange in the spout. Preferred features of the device according to the invention appear from the accompanying claims 2 to 8.

Et utførelseseksempel av oppfinnelsen er vist på tegningen. En ventil 1 er innvulkanisert i en sirkelrund åpning 2 i en sekkvegg 3 tilhørende en oppdriftssekk 4. An embodiment of the invention is shown in the drawing. A valve 1 is vulcanized in a circular opening 2 in a bag wall 3 belonging to a buoyancy bag 4.

Ventilen 1 ifølge oppfinnelsen representerer et alternativ for utligningsventiler av metall. The valve 1 according to the invention represents an alternative for compensating valves made of metal.

Den egentlige ventil 1 består av en mykelastisk, omtrent T-formet tut 5 med en bølge-flens 6, en utad konisk innsnevrende trakt 7 og en elastisk ring 8. Ringen 8 ligger i nær-heten av ventilens 1 utløp 9. Ventilens 1 utløp 9 vil ved oppblåst oppdriftssekk 4 ligge i planet 10, hvor ytterveggen 11 til sekkveggen 3 ligger. Den bølgeformede flens 6 er vulkanisert til en konusholder 12, hvis konisitet er motsatt rettet relativt trakten 7. Konusholderen 12 er vulkanisert til innveggen 13 i sekkveggen 3. Konusholderen 12 består av et litt mindre elastisk materiale. The actual valve 1 consists of a soft-elastic, roughly T-shaped spout 5 with a wave flange 6, an outwardly conical narrowing funnel 7 and an elastic ring 8. The ring 8 is located in the vicinity of the valve 1 outlet 9. The valve 1 outlet 9, when the buoyancy bag 4 is inflated, will lie in the plane 10, where the outer wall 11 of the bag wall 3 is located. The wavy flange 6 is vulcanized to a cone holder 12, whose taper is oppositely directed relative to the funnel 7. The cone holder 12 is vulcanized to the inner wall 13 of the bag wall 3. The cone holder 12 consists of a slightly less elastic material.

Bølgene i flensen 6 muliggjør at ventilen 1 kan unnvike sideveis ved ytre belastninger. Dessuten medfører bølgeformen at belastningen på ventilen 1 som følge av lastveksling-er blir liten. The waves in the flange 6 make it possible for the valve 1 to deflect sideways in the event of external loads. In addition, the waveform means that the load on the valve 1 as a result of load switching becomes small.

Traktens 7 koniske ende danner lukkedelen som følge av kontraksjonsmuligheten til det elastiske materiale i tuten 5. Lukkemekanismen understøttes av den elastiske ring 8. Ringen 8 er enten en integrert del av trakten 7 eller kan være eksempelvis kraft- eller formsluttende festet til trakten 7. The conical end of the funnel 7 forms the closing part as a result of the possibility of contraction of the elastic material in the spout 5. The closing mechanism is supported by the elastic ring 8. The ring 8 is either an integral part of the funnel 7 or can be, for example, force- or form-lockingly attached to the funnel 7.

Tuten 5 kan også være tilformet ved en tilforming av sekkveggen 3. The spout 5 can also be shaped by shaping the bag wall 3.

Med flere i sekkveggen 3 anordnede ventiler 1 vil det i sum foreligge et større strøm-ningstverrsnitt, slik at innertrykket i oppdriftssekken 4 raskt kan tilpasse seg endrede trykkforhold, eksempelvis under en oppstiging av oppdriftssekken 4. With several valves 1 arranged in the bag wall 3, there will in total be a larger flow cross-section, so that the internal pressure in the buoyancy bag 4 can quickly adapt to changing pressure conditions, for example during an ascent of the buoyancy bag 4.

Med flere ventiler 1 er man også sikret at alltid et tilstrekkelig antall ventiler 1 virker, også i de tilfeller hvor oppdriftssekken 4 et eller annet sted skulle ligge an mot en vegg. With several valves 1, it is also ensured that a sufficient number of valves 1 always work, also in cases where the buoyancy bag 4 should lie against a wall somewhere.

Ved en øking av innertrykket i oppdriftssekken 4 vil som følge av ventilens 1 oppbyg-ning allerede små trykkforskjeller på ca. 0,1 bar reguleres på en finfølgende måte. Ved en øking av innertrykket blir utløpet 9 tilsvarende utvidet, mot kraften til den elastiske ring 8, og det i oppdriftssekken 4 forhåndenværende medium, såsom trykkgass, vil strømme gjennom ventilene 1 helt til ventilen 1 eller ventilene 1 lukker igjen som følge av redusert trykkforskjell henholdsvis som følge av forspenningen i utløpet 9 eller i ringen 8. In the event of an increase in the internal pressure in the buoyancy bag 4, as a result of the construction of the valve 1, small pressure differences of approx. 0.1 bar is regulated in a fine-tuned manner. With an increase in the internal pressure, the outlet 9 is correspondingly expanded, against the force of the elastic ring 8, and the medium present in the buoyancy bag 4, such as compressed gas, will flow through the valves 1 until the valve 1 or the valves 1 close again as a result of a reduced pressure difference, respectively as a result of the bias in the outlet 9 or in the ring 8.

Ventilene 1 er sikre, enkle og praktisk talt vedlikeholdsfrie. The valves 1 are safe, simple and practically maintenance-free.

Oppfinnelsen egner seg for alle faste, halvfase, elastiske legemer, såsom oppdriftssekker, hvor trykkforskjellen mellom innsiden og utsiden er av betydning. Et eksempel er oppblåsbare skott for sperring mot inntrengende vann i mellomdekk ombord i ferger. The invention is suitable for all solid, half-phase, elastic bodies, such as buoyancy bags, where the pressure difference between the inside and the outside is important. An example is inflatable bulkheads for blocking against penetrating water in the middle deck on board ferries.

Legemene kan være av metall, plast, gummi, tekstil. The bodies can be made of metal, plastic, rubber, textile.
