Description

PATENTKRAV 1. Lagdelingsrør til fordeling og opbevaring af en indkommende væske med en vilkårlig temperatur i en opbevaringstank (3) til nævnte væske, hvori den opbevarede væske er lagdelt ved forskellige temperaturniveauer på grund af forskellige densiteter, lagdelingsrøret (7) er tilpasset til at strække sig vertikalt gennem væsken, der er opbevaret i tanken og omfatter en indløbsende og en udløbåbning tilvejebragt med en kontraventilanordning, der tillader en udstrømning af væske ind i tanken men forhindrer en indstrømning fra tanken ind i lagdelingsrøret, kendetegnet ved at udstrømningsåbningen er i form af en langstrakt åbning eller spalte (8) strækkende sig i den langsgående retning af lagdelingsrøret (7) og væsentlig langs med den hele længde af nævnte lagdelingsrør, og ved at kontraventilanordningen omfatter et langstrakt, fleksibelt element (11), der er fikseret i forhold lagdelingsrøret langs med en linje eller et område parallelt til den langsgående udstrækning af udstrømningsåbningen og der, selv eller sammen med andre fleksible elementer, overlapper åbningen fra ydersiden af lagdelingsrøret på en sådan måde at der tillades en udstrømning af væske ind i tanken ved at det fleksible element bliver deformeret lokalt og separeret fra lagdelingsrøret i området af et væskelag i tanken havende den samme temperatur som væsken i lagdelingsrøret, mens det forhindrer strømning i den modsatte retning. 2. Lagdelingsrør ifølge krav 1, kendetegnet ved at det omfatter en eller flere kontinuerlige spalter (8) , der i hovedsagen strækker sig langs med den hele længde af lagdelingsrøret. 3. Lagdelingsrørifølge krav 1 eller 2, kendetegnet ved at det omfatter et vinkelelement (9), der er lokaliseret ved en afstand udenfor spalten (8) og tilve- jebragt med huller (10). 4. Lagdelingsrør ifølge krav 3, kendetegnet ved at det totale hulareal af vinkelelementet (9) er mindst lige så stort som åbningsarealet af spalten (8). 5. Lagdelingsrør ifølge et hvilket som helst af de foregående krav, kendetegnet ved at kontraventil-anordningen omfatter to fleksible elementer (11) der er fikseret i forhold til lagdelingsrøret (7) på hver side af spalten (8). 6. Lagdelingsrør ifølge krav 5, kendetegnet ved at de to fleksible elementer (11) ligger an imod hinanden langs med deres respektive langsgående kanter. 7. Lagdelingsrør ifølge et hvilket som helst af de foregående krav, kendetegnet ved at det omfatter en afluftning og droslingsanordning, der er indeholdt i et øvre rørparti (18) af lagdelingsrøret og der omfatter en spoleformet krop (20) der tilspidser i tværsnittet imod enderegionerne, med den største tværsnitsdimension i et midterparti (21) på en sådan måde at en strømningsbe-grænsende passage (22) er dannet mellem indersiden af rørpartiet og midterpartiet af den spoleformet krop. 8. Lagdelingsrør ifølge krav 7, kendetegnet ved at den spoleformet krop (20) har form af to kegler, hvis baser er vendt for at stå overfor hinanden. 9. Lagdelingsrør ifølge krav 7 eller 8, kendetegnet ved at to kamre er defineret i afluftning og dros-lingsanordningen, nemlig et øvre kammer (23) over midterpartiet (21) af den spoleformet krop og et nedre kammer (23) under midterpartiet, det øvre kammer (23) star i forbindelse med den omgivende atmosfære via en trykudligningspassage (27) .PATENT REQUIREMENTS 1. Layer pipes for distributing and storing an incoming liquid at any temperature in a storage tank (3) for said liquid, wherein the stored liquid is layered at different temperatures due to different densities, the layer pipes (7) being adapted to stretch vertically through the liquid stored in the tank and comprises an inlet end and an outlet opening provided with a non-return valve device which permits an outflow of liquid into the tank but prevents an inflow from the tank into the layering tube, characterized in that the outlet opening is in the form of a an elongated opening or slot (8) extending in the longitudinal direction of the layering tube (7) and substantially along the entire length of said layering tube, and in that the non-return valve means comprises an elongated flexible member (11) fixed relative to the laying tube along with a line or area parallel to the longitudinal path end extension of the outflow opening and there, even or together with other flexible elements, the opening from the outside of the stratification tube overlaps in such a way as to allow a flow of liquid into the tank by deforming the flexible member locally and separated from the stratification tube in the region of a liquid layer in the tank having the same temperature as the liquid in the stratification tube while preventing flow in the opposite direction. Layering pipe according to claim 1, characterized in that it comprises one or more continuous slots (8) extending substantially along the entire length of the laying pipe. Laying pipe according to claim 1 or 2, characterized in that it comprises an angular element (9) located at a distance outside the gap (8) and provided with holes (10). Laying pipe according to claim 3, characterized in that the total hollow area of the angular element (9) is at least as large as the opening area of the slot (8). Layer pipe according to any one of the preceding claims, characterized in that the non-return valve device comprises two flexible elements (11) fixed relative to the layer pipe (7) on each side of the slot (8). Laying pipe according to claim 5, characterized in that the two flexible elements (11) abut each other along their respective longitudinal edges. Layer pipe according to any one of the preceding claims, characterized in that it comprises a vent and throttle device contained in an upper pipe portion (18) of the layer pipe and comprising a coil-shaped body (20) tapering in the cross-section towards the end regions. , with the largest cross-sectional dimension in a center portion (21) in such a way that a flow limiting passage (22) is formed between the inside of the pipe portion and the middle portion of the coil-shaped body. Layer pipe according to claim 7, characterized in that the coil-shaped body (20) is in the form of two cones whose bases are turned to face each other. Layering pipe according to claim 7 or 8, characterized in that two chambers are defined in the venting and throttling device, namely an upper chamber (23) above the central portion (21) of the coil-shaped body and a lower chamber (23) below the central portion, the upper chamber (23) communicates with the ambient atmosphere via a pressure equalization passage (27).
