I behallaren uppstar en sedlinentering ay yhtskan varfor det Sr onskvart att vid dessa hada operationer undvika aterinblandninq •ay de sedimenterade vatskorna eller fasta bfororeningarna, som avlagrats pa behallarens botten. Salunda innehalla bransleeisterrier alltid en viss mangd vatten, som harror fran kondensering, samt fasta fororeningar, som tillfalligt infarts vid yatskans hantering. Vattnet och dessa fororeningar avskiljas genom tyngdverkan och bilda ett lager vid bottnen av behallaren. For att forhindra, att detta lager medfores vid tappning av yatska ur behallaren eller virvlas upp yid pafyllning ay vatska i behallaren, ha anordningar ay °vanniimnt slag foreslagits. Genom att medelst denna anordning avtaga vatska i narheten av dess ovre fria yta tages vaiskan Iran den del ay yatskemassan i behallaren, som forst undergatt sedimentering. In the container, a sedimentation occurs on the surface, which is why it is advisable to avoid remixing of the sedimented liquids or solid contaminants, which have been deposited on the bottom of the container, during these operations. Salunda, industry leisterries always contain a certain amount of water, such as grains from condensation, as well as solid pollutants, which occasionally enter during the handling of the yat tank. The water and these contaminants are separated by gravity and form a layer at the bottom of the container. In order to prevent this layer from being entrained when draining water from the container or swirling during filling with liquid in the container, devices of a different type have been proposed. By removing liquid near this upper free surface by means of this device, the liquid Iran is taken from the part of the yat mass in the container which has first undergone sedimentation.

Den i fig. 1 visade markcisternen är en liggande, cylindrisk platcistern 1 med stor diameter och stor langd nedsankt i en vall 2 och tillganglig vid andarna genom inspektionsbrunnar 3 och 4, som skydda manhal 5 och 6 i cisternen. Det forsta 5 av dessa utgoras av en rorstuts 7, och bada aro tillslutna med lock 8 resp. 9. Mellan manhalen är anbragt ett luftningsror 10. I bottnen av cisternen är anbragt en renslucka 11. En ledning 12 for-binder cisternen med en icke visad pump Over en avstangningsventil 13. The ground cistern shown in Fig. 1 is a horizontal, cylindrical flat cistern 1 with large diameter and large length sunk in a dike 2 and accessible by the spirits through inspection wells 3 and 4, which protect manhole 5 and 6 in the cistern. The first 5 of these consist of a rudder nozzle 7, and both are closed with lids 8 resp. 9. An aeration pipe is arranged between the manhole 10. A cleaning hatch 11 is arranged in the bottom of the cistern. A line 12 connects the cistern to a pump (not shown) over a shut-off valve 13.
Ledningen 12 är f6rd genom rorstutsen 7 och pa innersidan ay denna krokt nedat och fOrlangd medelst ett fast, vertikalt ledningsr8r 14 till en niva i jamnhojd med cisternens langdaxel. Nedre anden av roret 14 är led-hart forbunden med en med stigareroret kommunicerande, rorformig flottorarm 15, vars fria ande uppbares av flottorer 16. Alternativt kan ledningen fOras in I cisternen genom mitten av dess ena gavel och vara forsedd med en horisontal, inre anddel 17, som ersatter r8- ret 14 och till vars ande flottorarmen 15 an ansluten. Ledningen 12, roret 14 eller 17 och flottiirarmen 15 bilda tillsammans en ledning, som tjanar bade till fyllning och tappfling av cisternen. Flottorarmens 15 med roret 14 forbundna Linde ãr lampligen gaffelformigt forgrenat och med forgreningens skanklar pa lampligt satt kring en horisontal axel svangbart lagrad pa andarna av en pa anden av roret 14 anordnad, tvargaende rOrdel. The conduit 12 is passed through the pipe connection 7 and on the inside of this hook downwards and extended by means of a fixed, vertical conduit 14 to a level flush with the longitudinal axis of the cistern. The lower spirit of the rudder 14 is articulated to a rudder-shaped floating arm 15 communicating with the riser rudder, the free spirit of which is supported by floats 16. Alternatively, the conduit may be carried into the cistern through the center of one end and be provided with a horizontal inner portion. 17, which replaces the r8 14 and to whose spirit the float arm 15 is connected. The conduit 12, the rudder 14 or 17 and the float arm 15 together form a conduit which serves both for filling and tapping the cistern. The Linde of the raft arm 15 connected to the tube 14 is suitably fork-shaped branched and with the shanks of the branch suitably mounted around a horizontal axis pivotally mounted on the spirits by a transverse tube part arranged on the spirit of the tube 14.
Pa den fria, yttre anden ay flottorarmen: Sr, sasom visas i fig. 2-4, fast en rordel 48, som är forsedd med en utvidgning 49, innehallande en avstangningsanordning. Pa en yttre andflans av denna rordel 48 är fast mittgrenen 50 av ett T-ror, vars tvardel 51 bil dar ett symmetriskt, horisontalt rat. (fig. 3), vars andar utmynna i cisternens inre genom rorets oppna andar pa omse sidor om det vertikala svangningsmittplanet f5r flott5rarmen. Genom tva symmetriska utsprang 52 pa tvarroret 51 är ford en axe! 53, pa vars utskjutande andar aro svangbart lagrade tva plattformiga delar 54, pa vilka medelst byglar aro fasta flottorer 16. Dessa kunna ha godtycklig form men ha stor volym och gores foretradesvis cylindriska. Medan deras diameter an begransad till den inre diametern av manhalet, kan namligen deras langd uppga till flera ganger denna diameter. Till folj d av sin symmetriska anordning ãr resultanten av flottorernas uppdrift belagen i flottorarmens rorelsemittplan. Den svangbara lagringen av flottorerna kring den tvargaende axeln 53 medger, att flottorerna alltid intaga horisontalt lage, dvs. parallellt med vatskenivan i cisternen, medan flottorarmen alltefter nivahoj den intar olika vinkellagen 1 forhallande till vatskeytan. On the free, outer spirit of the float arm: Sr, as shown in Figs. 2-4, fixed a rudder part 48, which is provided with an extension 49, containing a shut-off device. On an outer end face of this rudder part 48 is fixed the middle branch 50 of a T-tube, the transverse part 51 of which forms a symmetrical, horizontal line. (Fig. 3), the spirits of which open into the interior of the cistern through the open spirits of the tube on opposite sides of the vertical center of oscillation of the float arm. Through two symmetrical projections 52 on the transducer 51, the shaft is an axis! 53, on whose projecting spirits are pivotally mounted two flat parts 54, on which by means of stirrups are fixed floats 16. These can have any shape but have a large volume and are preferably made cylindrical. While their diameter is limited to the inner diameter of the manhole, their length can be several times this diameter. As a result of its symmetrical arrangement, the resultant of the buoyancy of the fleets is located in the center of motion of the fleet arm. The pivoting bearing of the floats around the transverse axis 53 allows the floats to always assume a horizontal bearing, ie. parallel to the water level in the cistern, while the float arm according to the level height it occupies different angular layers 1 relative to the water surface.
Flott8rerna 16 kunna utgoras av ihâliga kroppar ay metall eller foretradesvis av ett inert konstmaterial, sasorn glasfiberarmerad plast. Flott8rerna kunna emellertid aven utgOras ay kroppar av latt material, t. ex. skumplast. liven de i vatskan nedsankta, rOrformiga delarna kunna vara framstallda av plast. The floats 16 may be made of hollow bodies of metal or preferably of an inert art material, such as glass fiber reinforced plastic. However, the floats can also be made of bodies of light material, e.g. foam plastic. The tubular, submerged parts of the liquid can be made of plastic.
Den genom utvidgningen 49 av r8rdelen 48 bildade kammaren är delad genom en cylindrisk vagg 55, som är koaxiell med rordelen och stracker sig langs dess mittparti. Den av vaggen 55 bildade cylindern an oppen i hada andarna samt fasthallen i rordelen medelst radiella flansar 56, sa att rordelen uppdelas i en axial cylinder och en yttre passage, bildad mellan flansarna 56. Den Ovre delen av utvidgningens 49 vagg Or mellan tva flansar 56 forsedd med en kort cylindrisk an-sets 57 (fig. 3, 4), sbm kommunicerar med den ena am de mellan flansarna 56 inneslutna kanalerna. Pa denna ansats 57 Or fast ett ventilholje 58, vars sidovaggar aro forsedda med hal 59. VentilhOljet bildar pa sin mot ansatsen vanda del ett sate for tallriken 60 till en overtrycksventil, som medelst en fjader Or belastad med en bestamd kraft. Ventilens vertikala spindel 62 Or styrd i ett nay i den ovre vaggen ay ventilholjet och skjuter utanfor detta. The chamber formed by the expansion 49 of the tube portion 48 is divided by a cylindrical cradle 55 which is coaxial with the tube portion and extends along its central portion. The cylinder formed by the cradle 55 is open in the hot breaths and the retaining member of the rudder part by means of radial flanges 56, so that the rudder part is divided into an axial cylinder and an outer passage, formed between the flanges 56. The upper part of the extension 49 cradle Or between two flanges 56 provided with a short cylindrical attachment 57 (Figs. 3, 4), sbm communicates with one of the channels enclosed between the flanges 56. Attached to this shoulder 57 is a valve housing 58, the side cradles of which are provided with a hole 59. The valve housing forms on its opposite part of the shoulder a seat for the plate 60 to a pressure relief valve, which by means of a spring is loaded with a certain force. The vertical spindle of the valve 62 Or is guided in a nay in the upper cradle ay the valve housing and projects outside it.
I cylindern Or forskjutbart styrd en avstangningskolv 63 av samma langd som cylindern, vilken kolv vid sin mot flottorarmsrarets mynning vanda ande an fOrsedd med en cylindersektionen fyllande tvarvagg. Kolyens cylindriska del Sr anordnad att i kolyens langst utat (till hoger i fig. 2) forskjutna lage avstanga forbindelsen mellan den yttre passagen och rordelens 48 yttre mynning. Kolvens forskjutning astadkommes med 101- jande mekanism. In the cylinder Or slidably guided a shut-off piston 63 of the same length as the cylinder, which piston at its habit towards the mouth of the float arm arm is provided with a transverse wall filling a cylinder section. The cylindrical part Sr of the casing is arranged to in the furthest outwardly displaced layer (to the right in Fig. 2) close off the connection between the outer passage and the outer mouth of the rudder part 48. The displacement of the piston is achieved by a 101st mechanism.
Pa en kolvtapp 64, som Or anbragt i tva — —3 motstaende, inre nay 65 ungefar pa halften av kolvens langd, ãr lagrad ena anden av en vevstake 66, som medelst tva hylsor 67 ãr med litet, asiellt spelrum centrerad mellan naven 65. I den yttre, gaffelformiga anden 68 av vevstaken är svangbart lagrad den ena armen ay en vinkelhavstang 69, som gar genom en Oppning i den nedre delen av mittgrenen 50 till T-roret 50, 51 och som är vridbart lagrad i ett utsprang 70 pa denna mittgren. Vinkelhavstangens 69 andra, nedatriktade arm är vid sin nedersta ande ombojd till ett anslag 71 och uppbar en motvikt 72, som normalt halter denna arm i det i fig. 2 i heldragna linjer visade laget, i vilket aystangningskolven 63 i sin helhet befinner sig inuti cylindern 55. Pa den ovre armen av vinkelhavstangen 69 är tradd en plat 73, som medbringas vid vinkelhavstangens rorelse och tacker genomforingsoppningen for armen genom rorgrenen 50. On a piston pin 64, which Or is arranged in two - —3 opposite, inner nay 65 approximately half the length of the piston, one end of a connecting rod 66 is mounted, which by means of two sleeves 67 is with a small, axial clearance centered between the hubs 65. In the outer, fork-shaped spirit 68 of the connecting rod, one arm is pivotally mounted on an angular sea rod 69, which passes through an opening in the lower part of the central branch 50 to the T-tube 50, 51 and which is rotatably mounted in a projection 70 thereon. middle branch. The second, downward-pointing arm of the angular sea rod 69 is bent at its lower spirit to a stop 71 and carries a counterweight 72, which normally holds this arm in the layer shown in solid lines in Fig. 2, in which the aisle piston 63 is entirely inside the cylinder. 55. On the upper arm of the angular sea rod 69 is threaded a plate 73, which is carried along by the movement of the angular sea rod and thanks the passage opening for the arm through the rudder branch 50.
I den Owe va.ggen av mittgrenen 50 är anordnad en oppning med ett yttre utsprang 74, som är i huvudsak diametralt motsatt utspranget 70 och i vilket är lagrat en havstang 75, bestaende av en nedatriktad arm, som medelst en tapp 76 stoder mot den nedat riktade havstangens 69 ovre arm, och en uppatriktad, krokt arm, som upptill avslutas med ett avrundat anslag 77 och som vid sin krok uppbar en lamell 78, som är anordnad att vid svangning av havstangen 75 mot flottiirarmen samverka med den utskjutande anden av overtrycksventilens spindel 62. Arranged in the upper wall of the central branch 50 is an opening with an outer projection 74, which is substantially diametrically opposite the projection 70 and in which is mounted a sea rod 75, consisting of a downwardly directed arm, which by means of a pin 76 abuts the the upper arm of the sea rod 69 is directed downwards, and an upwardly directed, hooked arm, which terminates at the top with a rounded stop 77 and which at its hook carries a lamella 78, which is arranged to co-operate with the projecting spirit of the overpressure valve when pivoting the sea rod 75 towards the flotation arm. spindle 62.
Kolvens 63 andvagg är fOrsedd med en Opp-fling 79, som normalt Sr tillsluten medelst en undertrycksventil 80, som är betas tad av en kalibrerad fjader 81. Fjadern stOder mot en brygga 82, som Sr fast pa kolvens andvagg och som Even utgor en styrning for sugventilens spindel 83. Denna undertrycksventil uter, sasom framgar av det faljande, en anordning for att mojliggora tappning, nar cisternen fyllts till sin fyllningsgrans. The piston wall of the piston 63 is provided with an O-flap 79, which is normally closed by means of a negative pressure valve 80, which is actuated by a calibrated spring 81. The spring rests against a bridge 82, which is fixed to the piston wall of the piston and which even forms a guide for the suction valve spindle 83. This pressure relief valve, as is apparent from the following, provides a device for enabling tapping when the cistern is filled to its filling boundary.
Vid svangning av flottorarmen i vertikalplanet till foljd av andringar i vatskenivan i cisternen, ror sig tvarroret 51 i hojdled under bibehallande ay sitt horisontella ld.ge och under bibehallande av ett litet avstand under vatskenivan. Da tvarrorets 51 mynningar aro riktade horisontalt och symmetriskt at motsalta hall, kommer det ay vatskans rorelse saval vid fyllning som vid tappning berorda omradet att vara begransat till narheten av vatskans fria yta. Dessutom bilda de plattformiga organen 54, pd vilka flottOrerna aro fasta, ovanf Or tvarrorets 51 mynningar belagna skarmar, vilka forhindra bildandet av virvlar och insugning ay luft vid utsugning av vatska ur cisternen. Vid tappning sker utsugning av valska mom ett omrade, där vatskan Sr ren aven, om cisternen blivit fylld for kort tid sedan, da valskan nara ytan forst utsattes for sedimenteringsverkan. Vid fyllning infores vatskan i ett horisontalt plan nara ytan, och eventuella virvlar berora aid-rig cisternens botten, sti att de ateruppblanda i batten sedimenterade vatskor, slamm och andra fororeningar, som sjunkit till bottnen. When pivoting the float arm in the vertical plane as a result of changes in the water level in the cistern, the transverse tube 51 moves vertically while maintaining its horizontal length and while maintaining a small distance below the water level. Since the orifices of the transom 51 are directed horizontally and symmetrically towards the opposite salt hall, it will ay the movement of the water saval at filling which when tapping touch the area be limited to the vicinity of the free surface of the water. In addition, the flat members 54, on which the floats are fixed, form coated screens above the mouths of the whirlpool 51, which prevent the formation of vortices and the suction of air into the suction of liquid from the cistern. When tapping, suction of the roller is carried out in an area where the liquid is clean even if the cistern has been filled a short time ago, when the roller near the surface was first exposed to sedimentation. When filling, the liquid is introduced in a horizontal plane near the surface, and any vortices touch the bottom of the aid-rig cistern, so that they remix in the bath sedimented water, sludge and other contaminants, which have sunk to the bottom.
Nar flottorarmen, beroende pa variationer i vatskenivan i cisternen, narmar sig cisternens nedre vagg yid tappning resp. cisternens Ovre vagg vid fyllning, traffar havstangens 69 anslagsande 71 resp. haystangens 75 anslagsande 77 den ifragavarande vaggen. When the float arm, depending on variations in the water level in the cistern, approaches the lower cradle of the cistern near tapping resp. the Upper cradle of the cistern when filling, hits the abutment 71 resp. the abutment 77 of the haystack 75 strikes the cradle in question.
I fOrsta fallet, glider anslagsanden 71 pa den nedatriktade havstangen 69 hings den nedre vaggen samtidigt, som flottorarmen canker sig ytterligare, varvid havstangen svanges medurs relativt flothirarmen och utovar en dragning pa avstangningskolven 63. I andlaget, mar den nedre cisternvaggen relativt flottorarmen uppnatt det i fig. 2 med betecknade laget, inta flottOrerna laget 16A och haystangen 69 laget 69A, varvid aystangningskolven 63 intar sitt yttre, hogra andlage, som antydes med streckprickade linjer i fig. 2, och som bestammes am ett inre anslag 84. Darvid avstanger kolven 63 den yttre an-den 48 av flottiirarmen. Pumpen kan da icke langre tappa mera vatska ur cisternen och flottorarmen avstannas i sitt nedre andlage, i vilket dess yttre mynning fortfarande befinner sig pa visst avstand fran bottnen Over bottenskiktet ay vatten och fororeningar. Detta nedre andlage behover dock icke nodvandigtvis uppnas, innan fly vatska pumpas in i cisternen. In the first case, the abutment spirit 71 on the downwardly directed sea rod 69 slides the lower cradle at the same time as the float arm cancels further, the sea rod swinging clockwise relative to the float arm and exerting a pull on the shut-off piston 63. In the abutment, Fig. 2 with the designated layer, take the float layer 16A and the hoist rod 69 the layer 69A, the aisle piston 63 occupying its outer, right abutment, which is indicated by dash-dotted lines in Fig. 2, and which is determined by an inner stop 84. Thereby the piston 63 the outer second 48 of the flotation arm. The pump can then no longer drain more liquid from the cistern and the float arm is stopped in its lower vessel, in which its outer mouth is still at a certain distance from the bottom. Over the bottom layer of water and contaminants. However, this lower capacity does not necessarily need to be reached before liquid is pumped into the cistern.
Om emellertid flottOrarmen 15 i bOrjan am fyllningen befinner sig i sitt nedre andlage, befinner sig kolven 63 i avstangningslaget, sa att den inpumpade vatskan icke kan stromma ut den vanliga vagen, dvs. genom tvarroret 51. Darfor uppstar dã en tryckhojning i ledningen, vilken hojning Sr tillräcklig for att lyfta overtrycksventilen 60 fran sitt sate och slappa vatskan genom denna ventil. Nar vatskenivan i cisternen darigenom hoj Is tillrackligt for att den nedatriktade havstangen 69 skall kunna svanga ned till sitt normala lage, aterfores kolven 63 till laget inuti cylindern 55, varigenom den normala utloppsvagen genom tvarroret 51 ater Oppnas. However, if the float arm 15 at the beginning of the filling is in its lower abutment, the piston 63 is in the shut-off layer, so that the pumped liquid cannot flow out of the usual carriage, i.e. through the transducer 51. Therefore, a pressure rise occurs in the line, which rise is sufficient to lift the pressure relief valve 60 from its seat and release the liquid through this valve. When the water level in the cistern thereby raises ice sufficiently for the downwardly directed sea rod 69 to be able to swing down to its normal position, the piston 63 is returned to the layer inside the cylinder 55, whereby the normal outlet wave through the transverse tube 51 is opened again.
Nar anslagsanden 77 pa den Ovre havstangen 75 vid cisternens fyllning natt cisternens Ovre vagg, glider den kings densamma och havstangen 75 svanges moturs och medbringar genom tappen 76 den Ovre anden ay den med motvikt forsedda havstangen 69 medurs, dvs. i samma riktning som i slutet am tappningen.

All utstriimning av vatska genom flottorarmen är da forhindrad. For att undvika ett for stort overtryck i ledningarna, Sr pumpen forsedd med en kand overtrycks- - sakring. Pumpens avstannande kan Sven, sasom ovan antytts, styras automatiskt, nar cisternen fyllts till viss Oin flottorarmen vid fyllningen natt det ovre andlaget, kvarhalles avstangningskolven 63 i avstangningslaget, sa lange vatskenivan i cisternen icke andras. Tappning kan dS joke ske den normala vagen, men undertrycksventilen 80 avlyftes av undertrycket, som vid utpumpning uppstar i ledningen, och vatska kan tappas genom denna ventil. Nfir vfitskenivan pa. sa salt sankts sa. mycket, att flottOrarmen sankts tillrackligt fOr att havstangen 75 under inverkan av motvikten pa haystangen 69 aterftirts till det normala lfiget, aterfores kolven 63 till det inre av cylindern 55 och friger ater vatskans fria passage genom tvarriiret 51. When the stop spirit 77 on the upper sea rod 75 at the filling of the cistern at night the upper cradle of the cistern, the king's slides the same and the sea rod 75 swings counterclockwise and carries through the pin 76 the upper spirit ay the counterbalanced sea rod 69 clockwise, i.e. in the same direction as at the end am bottling. The shut-off piston 63 is displaced (added to the closing layer. When the cistern wall relative to the float arm reaches the layer designated 1B in Fig. 2, the floats take the layer 16b relative to the float arm and the sea rod 75 the layer 75B. The lamella 78 arranged on the sea rod 75 depresses the valve stem 62 and blocks the overpressure valve 60 in a closed position. The piston then assumes the shut-off layer. All outflow of liquid through the float arm is then prevented. To avoid an excessive overpressure in the lines, the pump is fitted with a pressure override fuse. Sven, as indicated above, can be controlled automatically, when the cistern is filled to a certain Oin float arm at the filling night the upper abutment, the shut-off piston 63 is retained in the shut-off layer, as long as the water level in the cistern does not change.Tapping can dS joke happen the normal way, but the negative pressure valve 80 is lifted by the negative pressure, which during pumping arises in the line, and liquid can be drained through this valve. Nfir vfitskenivan pa. sa salt sankts sa. that the float arm is lowered sufficiently so that the sea rod 75, under the influence of the counterweight on the haystack 69, returns to normal life, the piston 63 is returned to the interior of the cylinder 55 and releases the free passage of the liquid through the transverse 51 again.
Vid den i fig. 5 visade, andrade utfOringsformen av den nedatriktade havstangen, Sr denna sammansatt av tva delar, namligen en arm 85, som uppbar motvikten 72 och som vid 86 Sr lagrad i mitten pa en arm 87, som Sr lagrad pa. vevstaken 66. Vid den fria anden av armen 87 och vid ett stalle av armen 85, soni Sr belagen pa samma avstand frail lagringspunkten 86, Sr fast anden av en bowden. kabel 88 resp. anden av bowdenkabelns holje 89. Denna kabel Sr ford till cisternens yttre t. ex. genom manhalet 7, for att man medelst denna shall kunna utifran andra vinkeln mellan armarna 85 och 87. Darigenom blir det mojligt att andra laget av armens 85 andanslag 71 i forhallande till avstfingningskolven och darigenom att installa flottorarmens nedre andlage, alltefter tjockleken av det pA hot-ten samlade skiktet av vatten och f5roreningar. In the second embodiment of the downwardly directed sea rod shown in Fig. 5, it is composed of two parts, namely an arm 85, which carried the counterweight 72 and which at 86 is mounted in the middle of an arm 87, which is mounted on. the connecting rod 66. At the free spirit of the arm 87 and at a stable of the arm 85, soni Sr coated at the same distance from the storage point 86, Sr fixed the spirit of a bowden. cable 88 resp. the spirit of the bowden cable housing 89. This cable Sr ford to the outside of the cistern e.g. through the manhole 7, so that by means of it the other angle between the arms 85 and 87 can be seen from it. This makes it possible for the second layer of the arm 85 to strike 71 in relation to the launch piston and thereby to adjust the lower arm of the naval arm, according to the thickness of the pA threat. -ten collected the layer of water and contaminants.
Vid den i fig. 6 visade utforingsformen Sr tvarvaggen pa kolven 63 stelt forbunden med en med kolven koaxiell kolvstang 90, vars yttre ande Sr krokt i form av en vagga med tva andanslag 91 och 92. Tva vertikala och sinsemellan parallella armar 93 och 94, som aro forda genom en oppning i den byre vfiggen av tvarroret 51, aro lagrade i utsprang 95 och 96 pa. en tvarstang 97, som forbinder de svangbara barorganen 54 for flottorerna 16, som darigenom Oro stelt forbundna med varandra. De nedre andarna av armarna 93 och 94 aro belagna i det inre av vaggan mellan dess and- anslag 91 och 92 och aro dar fOrsedda med tvargaende anslag 98 och 99. Vid armarnas 04 och 93 ovre andar aro fasta anden av kabeln 100 resp. 1051jet 101 till en bowdenkabel, liknande den, som visas i fig. 5. In the embodiment shown in Fig. 6, the transverse cradle of the piston 63 is rigidly connected to a piston rod 90 coaxial with the piston, the outer end of which is hooked in the form of a cradle with two breath stops 91 and 92. Two vertical and mutually parallel arms 93 and 94, which are passed through an opening in the byre vfiggen of the transverse tube 51, are stored in projections 95 and 96 pa. a cross bar 97, which connects the pivotable bar members 54 of the floats 16, thereby thereby rigidly connected to each other. The lower ends of the arms 93 and 94 are located in the interior of the cradle between its end stops 91 and 92 and are provided with transverse stops 98 and 99. At the upper ends of the arms 04 and 93 are fixed spirit of the cable 100 and 100, respectively. 1051jet 101 to a bowden cable, similar to that shown in Fig. 5.
Vid svangning av flottiirarmen 15 medfOr den relativa svangningen av den av flottorer- na 16 bildade enheten en andring av armarnas 93 och 94 lutning. Avstandet mellan ar- mamas nedre iindar kan installas medelst bowdenkabeln 100, 101. Vid en viss lutning av flottorarmen uppat traffar anslaget 98 pa. armen 93 anslaget 91, och vid lutning nedat traffar anslaget 99 pa. armen 94 anslaget 92 i vaggan. Om flottorarmen fran ett sa.dant 'age fortsatter sin rorelse i samma riktning, kommer flagon av armarna 94 eller 93 att forskjuta avstangningskolven at hoger eller at vanster i fig. 6. Vid slutet av flottorarmens svangningsrOrelse avstanger kolven passagen langs yttersidan av cylindern 55 vid den hogra resp. vanstra anden av rordelen 50. I fig. 6 ha varken overtrycksventilen eller undertrycksventilen visats, men det Sr klart, att sadana anordnas pa samma salt som enligt fig. 2 och 4. When the float arm 15 is pivoted, the relative pivoting of the unit formed by the floats 16 causes a change in the inclination of the arms 93 and 94. The distance between the lower ends of the arms can be installed by means of the bowden cable 100, 101. At a certain inclination of the float arm upwards, the stop hits 98 pa. the arm 93 strikes 91, and when sloping downwards strikes 99 pa. arm 94 abutment 92 in the cradle. If the float arm from such an age continues its movement in the same direction, the flap of the arms 94 or 93 will displace the shut-off piston to the right or to the left in Fig. 6. At the end of the float arm swing movement, the piston stops the passage along the outside of the cylinder 55 at the hogra resp. In the figure 6, neither the overpressure valve nor the underpressure valve have been shown, but it is clear that such are arranged on the same salt as in Figs. 2 and 4.
Enligt- den i fig. 7 visade utforingsformen 5.r avstangningskolven anordnad i del fasta raret 14. Ett mellanror 102 Sr fOrsett med en utvidgning 103 pa ena sidan °ch har sin tvarsektion uppdelad i en cylindrisk del 104 i rorets 14 axel och en sidokanal 105 av samma tvarsektionsarea medelst en inre cylindervagg 106, som vid vardera anden kvarlamnar en fOrbindelse mellan sektionens hada delar. En avstangningskolv 63 Sr forskjutbart styrd i den cylindriska delen och Sr anordnad att kunna avstanga den ena eller andra av forbindelseoppningarna genom axiell forskjutfling uppat eller nedat. Liksom i de forut beskrivna utforingsformerna Sr en undertrycksventil 80 anordnad i kolvens tvarvagg och en overtrycksventil 60 i mellanrdrets vagg i sadant lage, att inloppet till denna ventil avstanges av avstangningskolven 63, nar denna befinner sig i silt 5vre andlage. En vevstake 107 forbinder kolven med en stang 108, som Sr anbragt mellan tva utsprang 109 i de vridbara hylsorna for flottorarmens lagring 1 sa.- dant lag; att den ligger i ett plan, som gar genom flottorarmens lagringsaxel och flott5rarmens mittaxel. According to the embodiment shown in Fig. 7, the shut-off piston is arranged in the part fixed to the tube 14. An intermediate tube 102 is provided with an extension 103 on one side and has its transverse section divided into a cylindrical portion 104 in the shaft 14 of the tube and a side channel. 105 of the same cross-sectional area by means of an inner cylinder wall 106, which at each second leaves a connection between the two parts of the section. A shut-off piston 63 is slidably guided in the cylindrical part and is arranged to be able to shut off one or the other of the connection openings by axial offset flapping up or down. As in the previously described embodiments, a negative pressure valve 80 is arranged in the transverse wall of the piston and an overpressure valve 60 in the cradle of the intermediate ring in such a position that the inlet to this valve is shut off by the shut-off piston 63 when it is in the upper face. A connecting rod 107 connects the piston to a rod 108, which is arranged between two projections 109 in the rotatable sleeves for the floating arm bearing 1 such a layer; that it lies in a plane which passes through the bearing axis of the float arm and the center axis of the float arm.
En svangning av flottorarmen 15 uppai eller nedat medfor salunda en motsvarande forskjutning uppat resp. neat av avstangningskolven. Vid tappning medfOr flottar- armens sankning en forskjutning ay kolven nedat till ett nedre andlage, i vilket stigarroret ar helt avstangt. En fyllning i detta lage av flottorarmen majliggOres, tack vare over- trycksventilen 60, tills hojningen av vatskenivan i cisternen fortskridit sa langt, att flottorarmen forskjutit kolven tillbaka till oppningslaget och fyllningen darefter kan fortsattas-genom flottorarmen. Vid ovre gran- sen f6r cisternens fyllning har den vid flot- torarmens hojning uppat forskjutna kolven avstangt forbindelsen vid byre anden av mel- lanroret 103 och inloppet till Overtrycksven- tilen 60. Tappning av cisternen vid denna niva kan ske genom undertrycksventilen 80, tills sankningen av vatskenivan och darmed ay armen aterfort .avstangningskolven till ett — — lage, i vilket den. friger den fond avstiingda f5rbindelsen. An oscillation of the float arm 15 up or down thus entails a corresponding displacement upwards resp. neat of the shut-off piston. When draining, the lowering of the float arm causes a displacement of the piston down to a lower abutment, in which the riser tube is completely shut off. A filling in this layer of the float arm is allowed, thanks to the overpressure valve 60, until the raising of the water level in the tank has progressed so far that the float arm has displaced the piston back to the opening layer and the filling can then be continued through the float arm. At the upper boundary for the filling of the cistern, the displaced piston at the elevation of the float arm has shut off the connection at the upper end of the intermediate pipe 103 and the inlet to the overpressure valve 60. Draining of the cistern at this level can take place through the negative pressure valve 80. of the water level and thus the arm aterfort .the shut-off piston to a - - layer, in which it. the fund releases the conditional connection.
I den forut beskrivna utforingsformen Sr flottorarmens yttre ande f5rsedd med ett vars tvargaende del Sr horisontal och har symmetriska mynningar, ovanfor var oeh en av vilka Sr anordnad ett plattformigt bar-organ for en Donor, vilket organ bildar en skarm for forhindrande av virvelbildning i vatskans yta. In the embodiment described above, the outer spirit of the float arm is provided with a transverse part Sr which is horizontal and has symmetrical mouths, above each of which Sr is arranged a flat bar member for a Donor, which member forms a screen for preventing vortex formation in the liquid. surface.
I fig. 8 visas en modifierad utforingsform, vid vilken en skarm Sr anordnad omedelbart ovanfor tvarrorets 51 mynning. Denna skarm bildas av en platta 110, som fast sammanhanger med barorganet 54. Derma platta Sr fast pa lagret for barorganet 54 pa axeln 53 parallelli med flottorens axel. Den forblir darfor alltid horisontal. I detta fall kan satet for flottoren pa barorganet 54 utgoras av en konkav badd 111, pa vilken flottoren Sr fast. Fig. 8 shows a modified embodiment, in which a screen Sr is arranged immediately above the mouth of the twist tube 51. This screen is formed by a plate 110, which is fixedly connected to the bar member 54. This plate is fixed to the bearing of the bar member 54 on the shaft 53 parallel to the axis of the float. It therefore always remains horizontal. In this case, the seat of the float on the bar member 54 may be constituted by a concave bath 111, on which the float is fixed.
EnHO en annan i fig. 9-10 visad variant av denna anordning Sr svangningsaxeln 112 for flottorerna anordnad koaxiellt med tvarroret 51 och uppburen av lager 113, som uppbaras av radiella stodflansar 114. I varje mynningsoppning av tvarroret 51 Sr fritt vridbart inskjutet ett anslutningsror 115 till en flat, cylindrisk burk med hela ovre och nedre plana gavlar 116 och med i den cylindriska sidovaggen anordnade oppningar 117, anordnade med 0 forskjutning relativt tvarrOrets 51 axel. Anslutningsroren 115 arc centrerade relativt axeln 112 medelst nay 118, som uppbaras centralt i anslutningsroren av radiella armar 119. Burkarna aro ph detta satt fritt vridbara kring- axeln 112. Pa yttersidan av varje anslutningsrar 115 Sr fastsvetsad en ring 120, som fast sammanhanger med bad-den 111 for en flottor. Dessas axlar aro parallella med burkarnas galvar 116, vilka darigenom bilda standigt horisontala skarmar, mellan vilka vatskestrommen gar radiellt i flera olika riktningar. Darigenom fOrhindras effektivt bildandet av ytvirvlar i viitskan vid ifyllning eller utsugning ur eisternen dels genom skarroverkan av burkgavlarna 16 dels genom uppdelning av vatskestrommen i flera horisontalt riktade delstrommar. Another variant of this device shown in Figs. 9-10 is the pivot axis 112 of the floats arranged coaxially with the rudder 51 and supported by bearings 113, which are supported by radial support flanges 114. In each orifice of the rudder 51 a connecting pipe 115 is freely rotatably inserted. to a flat, cylindrical can with the entire upper and lower flat ends 116 and with openings 117 arranged in the cylindrical side cradle, arranged with a displacement relative to the axis 51 of the transverse member 51. The connecting tubes 115 arc centered relative to the shaft 112 by means of nay 118, which is supported centrally in the connecting tubes by radial arms 119. The jars aro ph this sat freely rotatable circumferential shaft 112. On the outside of each connecting tubes 115 Sr is welded a ring 120, which is fixedly connected to bath -the 111 for a float. Their axes are parallel to the galls 116 of the cans, which thereby form constantly horizontal seams, between which the liquid stream runs radially in several different directions. This effectively prevents the formation of surface vortices in the whitening when filling or extracting from the ester, partly by the scarring effect of the can ends 16 and partly by dividing the liquid drum into several horizontally directed sub-drums.
Far r5rliga behallare, som t. ex. bransletankarna i ett flygplan, kunna flottorarmarlia och de clamed sammanhangande organen ges ett forenklat utforande, som Sr mindre skrymmande och darigenom battre lampat for det mom sadana behallare tillgangliga utrymmet. Far r5rliga containers, such as. the fuel tanks in an aircraft, the fleet armarlia and the clamed connecting bodies can be given a simplified design, which Sr less bulky and thereby better lamped for the mom such containers available space.
Vid den utforingsform av flottorarmen, som visas i fig. 11 och 12, och som Sr sarskilt lampligt f5r anvandning i behallare av sistnamnda slag, utgoras flottorerna joke av frail flottorarmen skilda kroppar utan av flytorgan, som aro fast anbragta runtom armen 15 och tvarroret 51. PS ritningen visas flytorgan i form av ett tjockt skikt 121 av ett mycket latt material. En dubbelvagg, som runtom roret 15 innesluter ett lufttatt tillslutet rum Ran anvandas i stallet. In the embodiment of the float arm shown in Figs. 11 and 12, which is particularly suitable for use in containers of the latter kind, the floats are made up of separate float arm bodies but of floating means fixed around the arm 15 and the transverse tube 51. The PS drawing shows floating means in the form of a thick layer 121 of a very light material. A double cradle, which around the rudder 15 encloses an airtight enclosed space Ran is used in the stable.
Avstangningsorganen besta i detta fall av vridbara spjall 122, 123, anordnade det ena efter det andra i flottorarmen 15, varvid vart och ett av spj alien paverkas av en aterforingsfjader 124 resp. 125, som f5rbinder en pa. riirets 15 yttersida fast anordnad tapp 126 med en arm 127 resp. 128, fast pa spjallets 122 resp. 123 axel 129 resp. 130. Spjallen hallas normalt oppna av fjadrarna och aro vrid- bara till stangningslaget av var sin med spjallaxeln fast forbunden arm, som samverkar med behallarevaggen, nar flottorarmen nar sitt Ovre resp. nedre andlage. The shut-off means in this case consist of rotatable dampers 122, 123, arranged one after the other in the float arm 15, each of the dampers being affected by a return spring 124 resp. 125, which connects a pa. fixed surface 126 of the tube 15 with an arm 127 resp. 128, fixed on the panel 122 resp. 123 axle 129 resp. 130. The slats are normally held open by the springs and are rotatable to the closing layer of each arm firmly connected to the slat shaft, which cooperates with the container cradle when the float arm reaches its upper resp. lower face.
Spjallet 122, som Sr avsett att stiingas i slutet av tappningen, har en nedatriktad arm 13. Vridningen till det med streckprickade linjer visade stangningslaget 122A astadkommes av armens 131 vridning genom sam- verkan med behallarens nedre vagg, da denna relativt armen intar det visade laget 1A, varvid armen intar laget 131A. En overtrycks- ventil 132 Sr anbragt i spjallet 122 och medger igangsattandet av fyllningen, tills armen ater lyfts till ett 'age, diir spjallet kan aterforas till oppet lage av sin flatter. The slat 122, which is intended to be stitched at the end of the tapping, has a downwardly directed arm 13. The rotation to the bar layer 122A shown in dashed lines is effected by the rotation of the arm 131 by co-operation with the lower cradle of the container, as this relatively arm occupies the shown layer 1A, with the arm occupying layer 131A. An overpressure valve 132 is located in the damper 122 and allows the filling to be initiated until the arm is raised again to an age at which the damper can be returned to the top layer of its flatter.
Spjallet 123 Sr avsett att stangas i slatet. av fyllningen av behallaren, och doss arm 133 straeker sig uppat. Dess stangningslage, an- tytt med 123B, bestammer flottorarmens ovre andlage, i vilket behallarens ovre vagg re- lativt armen intagit laget 1B och svangt armen 133 till laget 133B. En undertrycksventil 134 Sr anordnad i spjallet 123 och medger, att tappningen Sven i flottorarmens byre andlage paborjas, tills flottorarmen sankt sig och spjallet darvid ater borjat oppnas. The slat 123 Sr is intended to be stabbed in the slat. of the filling of the container, and doss arm 133 straightens upwards. Its closing stroke, indicated by 123B, determines the upper abutment of the float arm, in which the upper cradle of the container relatively the arm has taken over the layer 1B and swung the arm 133 to the layer 133B. A negative pressure valve 134 Sr is arranged in the damper 123 and allows the tapping Sven in the floating arm of the raft arm to be drilled until the raft arm sinks and the damper is then started to open again.
Avstangningsorganens verkningssatt Sr salunda Oven vid denna utforingsform fullt ana- log med verkningssattet av avstfingningsorganen enligt fig. 2-4. Dot Sr klart, att man yid utforingsformen enligt fig. 11 och 12 skulle kunna ersatta aterforingsfjadrarna med motvikter. Actuation of the shut-off means Sr salunda Even in this embodiment, it is fully analogous to the actuation of the shut-off means according to Figs. 2-4. It is clear that in the embodiment according to Figs. 11 and 12, the return springs could be replaced with counterweights.
Nar det Sr fraga om rorliga behallare, ligger en olagenhet dari, att den oversta delen av behallaren icke fylles till foljd av att fyll- ningsspjallet stanges genom anslag av armen 133 mot behallarens ovre vagg, innan behal- laren fullstandigt fyllts. Detta Sr sarskilt ofordelaktigt i samband med bransletankar pa flygplan, vilkas utrymme maste utnyttjas till det yttersta for transport av bransle. For att undvika denna olagenhet kan man till den nyss beskrivna avstangningsanordningen foga den anordningen, som visas i fig. 13 och 14. Enligt denna utf5ringsform Sr flottOrarmen 15 forsedd med en rorstuts 135, som kommunicerar med flottiirarmen genom en oppning, i vilken Sr anbragt en Overtrycksventil 136, som normalt halles stangd av en fjader 137. I rorstutsen 135 Sr anordnat ett spjall 138, vans axel 139 pa hada sidorna om rorstutsen 6— — uppbar tva parallella armar 140 fOr anslutning till ett styrorgan, innefattande en tradbygel, som stracker sig over flottorarmen 15 °eh vars skanklar 141 aro ledbart forbundna med andarna av armarna 140. Bygelns mitt-del 142 Or upptill forbunden med en ogla 143 pa nedre anden av en vertikal sting 144. Denna Or med visst spel styrd i en hylsa 145, som uppbares av ett stool 146, som Or fast ph flottorarmen 15. Ovanfor flottorernas 16 flytniva (vattenlinje) Or stangen 144 forbunden med en mindre, sfarisk flottor 147, som i flottorarmens uppfitsvangda lage befinner sig under en sluten rorstuts 148 eller utbuktning pa behallaren. When it comes to movable containers, there is a disadvantage in that the upper part of the container is not filled as a result of the filling slat being closed by abutment of the arm 133 against the upper cradle of the container, before the container is completely filled. This is particularly disadvantageous in connection with fuel tanks on aircraft, the space of which must be used to the utmost for the transport of fuel. To avoid this inconvenience, the shut-off device just described can be connected to the device shown in Figs. 13 and 14. According to this embodiment, the float arm 15 is provided with a rudder nozzle 135, which communicates with the float arm through an opening in which Sr. Pressure relief valve 136, which is normally held closed by a spring 137. In the rudder socket 135 is arranged a damper 138, the shaft 139 of which has the sides of the rudder socket 6 - has two parallel arms 140 for connection to a guide member, comprising a wire bar which extends over the raft arm 15 ° eh whose shanks 141 are articulated connected to the spirits by the arms 140. The middle part 142 of the yoke is connected at the top by an ogla 143 on the lower end of a vertical stitch 144. This Or with some play is guided in a sleeve 145, which supported by a stool 146, which is fixed to the floating arm 15. Above the floating level (waterline) of the floats 16 or the rod 144 connected to a smaller, spherical floats 147, which in the floating arm of the floating arm then the bearing is located under a closed pipe end 148 or bulge on the container.
Sa range flottorarmen icke natt sitt ovre andlage, kommer den lilla flottaren 147, som halles Over vatskeytan av flottorerna 16, att vim a pa ovre anden av hylsan 145 och spjallet 138 Mies darigenom Oppet. Shlunda fore-Egger mojlighet for vatskan att strOmma ut genom rorstutsen 135 under avlyftning av overtrycksventilen 136, nar spjallet 123 stanges genom havstangens 133 anslag mot behallarens ovre vagg. Denna overtrycksventil, som forblev stangd, sa lange flottorarmens utlopp kunde ske normalt genom tvarroret 51, Oppnas dh. under inverkan av pumptrycket, sh att vatska kan fortsatta att strOmma in i behallaren, sedan flottorarmen stannat i sitt ovre andlage. If the raft arm does not reach its upper abutment, the small raft 147, which is held over the water surface by the rafts 16, will be on the upper spirit of the sleeve 145 and the damper 138. However, Egger allows the liquid to flow out through the pipe nozzle 135 while lifting the pressure relief valve 136 when the damper 123 is closed through the abutment of the sea rod 133 against the upper cradle of the container. This pressure relief valve, which remained closed as long as the outlet of the float arm could normally take place through the twist tube 51, Oppnas dh. under the influence of the pump pressure, sh that liquid may continue to flow into the tank, after the float arm has remained in its upper capacity.
Vid denna fortsatta fyllning kommer den lilla flottoren 147 sh. smhningom att lyftas i utbuktningen 148 av den stigande vatskenivan och att darvid vrida spjallet 138 mot stangningslaget. Denna reglering Or sh anordnad, att spjallet 138 stanges fullstandigt, nar vatskenivan nar in i utbuktningen 148 till den med 149 betecknade nivan, som motsvarar den ovre fyllningsgransen. Darigenom utnyttjas behallarens kapacitet fullstandigt, och man undviker forlusten av nyttigt utrymme, som utan denna anordning uppstar ovanfor den av flott5rerna 16 bestamda iivre gransnivan. At this continued filling, the small float 147 sh. gradually to be lifted in the bulge 148 of the rising water level and thereby to turn the damper 138 towards the closing stroke. This control is arranged so that the damper 138 is completely closed when the water level reaches the bulge 148 to the level denoted by 149, which corresponds to the upper filling boundary. In this way the capacity of the container is fully utilized, and the loss of useful space is avoided, which without this device arises above the upper spruce level determined by the floats 16.
Vid fullstandigt fylld behallare paborjas tappningen ph det i samband med fig. 11 och 12 beskrivna sattet genom en undertrycksventil i spjallet 123, som icke visas i fig. 13 och 14, tills nivan filer sjunkit sa langt, att spjallet 123 ater oppnas. I borjan av en shdan tappning sjunker den lilla flottoren 147 ned och aterstaller spjallet 138 till oppet lage, men overtrycksventilen 136 forblir stangd, vilket hindrar tappning genom rorstutsen 135, som skulle fororsaka virvlar. Aven fyllningen sker normalt genom tvarrOret 51 utom i detta sista efterfyllningsskede, emedan Overtrycksventilen 136 fOrblir stangd, sh lange spjallet 123 Or oppet. In the case of a completely filled container, the tapping ph as described in connection with Figs. 11 and 12 is drilled through a negative pressure valve in the slit 123, which is not shown in Figs. 13 and 14, until the level of files has dropped so far that the slit 123 is opened again. At the beginning of such a tapping, the small float 147 sinks down and restores the damper 138 to the up position, but the pressure relief valve 136 remains closed, which prevents tapping through the rudder nozzle 135, which would cause vortices. The filling also normally takes place through the cross member 51, except in this last refilling stage, because the overpressure valve 136 remains closed, with the throttle 123 open.
Den i fig. 15 visade anordningen Or avsedd for cisterner for flytande bransle och utgor en sakerhetsanordning for forhindrande av tapp ning av i botten av cisternen samlat vatten, nar flottorarmen nar sitt nedre andlage. Detta vattenskikt kan namligen uppnh en Whacklig tjocklek, for att tvarroret 51 skall kunna sankas ned i detta, i fall flottorarmens nedatrorelse endast begransas genom anslag av armen 131 mot cisternens botten. DO. i sadant fall spjallet 122 annu star Oppet, tappas vat-ten tillsammans med det flytande branslet. The device Or shown in Fig. 15 is intended for liquid fuel tanks and constitutes a safety device for preventing draining of water collected at the bottom of the tank when the float arm reaches its lower surface. Namely, this water layer can reach a wobbly thickness, so that the transverse tube 51 can be sunk into it, in case the downward movement of the float arm is limited only by abutment of the arm 131 against the bottom of the cistern. DO. in such a case the throttle 122 annu star Oppet, the water is drained together with the liquid fuel.
Enligt denna utforingsform Or spjallets 122 styrning medelst den nedatriktade armen 131 kompletterad med en hjalpstyrning medelst en for olika tathet i vatskan kanslig flottor, som ieke flyter upp, nar den Or helt nedsankt i branslet, men som intar ett jamviktslage, nfir den Or nedsankt till halften i bransle och till halften i vatten. Denna flottor 150 Or fast ph en arm 151, som Or lagrad ph tvarroret 51 vid 152. En lank 153 forbinder armen 151 med ena armen 154 av en vinkelhaystang, som dr fast pa spjallets 122 axel 129. Den andra armen 155 av vinkelhaystangen Or medelst en fjader 156 fOrbunden med en tapp 157 pa flottorarmen 15, genom vilken spjallet 122 Aterfores till oppningslaget. According to this embodiment, the control of the throttle 122 by means of the downwardly directed arm 131 is supplemented by an auxiliary control by means of a fleet capable of varying degrees of fluidity, which does not float when fully immersed in the industry, but which assumes an equilibrium stroke. half in fuel and half in water. This raft 150 is fixed to an arm 151, which is mounted on the transverse tube 51 at 152. A length 153 connects the arm 151 to one arm 154 of an angle lift bar, which is attached to the shaft 129 of the damper 122. The other arm 155 of the angle lift rod Or a spring 156 connected to a pin 157 on the float arm 15, through which the damper 122 is returned to the opening layer.
Skiljeytan mellan vattenskiktet oeh brans-let betecknas med 158, varvid antages, att cisternen innehaller en onormalt stor mangd vatten. DO under tappning flottorerna 16 folja den sjunkande branslenivan, nar flottoren 150 vattenskiktet, innan armen 131 kommit i beroring med cisternens 1 botten. Flottoren 150 nar da snarl ett jainviktslage, och dess sankningsrorelse avstannas. Flottorarmen daremot fortsatter sin sankningsrorelse, varvid armen 151 svanges medurs relativt flottorarmen 15, varvid spjallet 122 stanges. Anordningen Or sh.dan, att detta stangningslage uppnas strax, innan tvarroret 51 natt skiljeytan 158 melIan vatten och bransle. Om daremot vattenmangden i cisternens bonen Or liten, vilket normalt Or fallet, nar armen 131 bottnen av behallaren, innan flottoren 150 stannats, och spjallets 122 stangning sker genom inverkan av armens 131 anliggning mot eisternvaggen. Flottoren 150 trader alltsa i verksamhet endast, om vattenskiktet i cisternens botten Or onormalt tjockt, och den beskrivna sakerhetsanordningen fungerar saledes endast I onormala fall. The interface between the water layer and the industry is denoted by 158, it being assumed that the cistern contains an abnormally large amount of water. DO while tapping the floats 16 follow the declining industry level, when the float 150 the water layer, before the arm 131 comes into contact with the bottom of the tank 1. The fleet 150 then snarls a jain weight stroke, and its sinking motion is stopped. The float arm, on the other hand, continues its sinking movement, the arm 151 being pivoted clockwise relative to the float arm 15, whereby the damper 122 is closed. The device Or sh.dan, that this closing layer is reached shortly, before the tverror 51 night the dividing surface 158 between water and fuel. If, on the other hand, the amount of water in the cistern's bone is small, as is normally the case, the arm 131 reaches the bottom of the container, before the float 150 has stopped, and the closing of the slat 122 takes place by the action of the arm 131 abutting the eistern wall. The float 150 thus enters into operation only if the water layer in the bottom of the cistern is abnormally thick, and the described safety device thus functions only in abnormal cases.
Den i fig. 16 och 17 visade utforingsformen visar en annan sakerhetsanordning. Ett hj alpspjall 159 Or anordnat i den vertikala rordelen 18, som nedtill avslutar stigareroret 14. AxeIn 160 till detta hjalpspjall uppbar tva armar 161, vilka genom en stang 162 Oro forbundna med andarna av armar 163, vilka Oro svangbara kring en axel 164, som Or fast i en vertikal stang 165, som utgor en forlangning nedat av det fasta roret 14 och straeker sig nastan till cisternens botten. Vid sina mellersta delar Oro armarna 163 vid 166 ledbart f5rbundna med lankar 167, som vid 168 aro svangbart lagrade ph en fOr olika vatsketat- — —7 het kanslig flottor 169, som är f8rskjutbart styrd langs den vertikala stangen 165. The embodiment shown in Figs. 16 and 17 shows another safety device. An auxiliary damper 159 is arranged in the vertical rudder part 18, which at the bottom terminates the riser 14. Axis 160 to this auxiliary damper carried two arms 161, which by a rod 162 are connected to the spirits of arms 163, which are pivotable about an axis 164, which Or fixed in a vertical rod 165, which forms a downward extension of the fixed tube 14 and extends almost to the bottom of the cistern. At its middle parts, the arms 163 at 166 are pivotally connected to longitudinal rods 167, which at 168 are pivotally mounted to a different body of fluid 169, which is slidably guided along the vertical rod 165.
Nar det i cisternens botten samlade vattenskiktet nar tillracklig tjocklek, lyfter det flattoren 169 till det i fig. 16 visade laget, armarna 163 svangas darigenom medurs, sa att hjalpspjallet 159 sLanges medelst stangen 162 och armarna 161. Mot det da av flottoren 169 intagna hojdlaget svarar den hogsta tillatna hOjdnivan av skiljeytan 171 mellan vatten och bransle. Vid denna och hogre vattennivan 171 är spjallet 159 stangt och stigarroret Sr avstangt bade fOr fyllning och tappning. When the water layer collected in the bottom of the cistern reaches a sufficient thickness, it lifts the flatter 169 to the layer shown in Fig. 16, the arms 163 are thereby pivoted clockwise, so that the auxiliary slat 159 is slung by the rod 162 and the arms 161. Towards the height layer then occupied by the float 169 corresponds to the maximum permissible height level of the interface 171 between water and fuel. At this and higher water level 171, the damper 159 is closed and the riser pipe Sr is shut off both for filling and tapping.
Ett sugror 170, som mynnar ut vid cisternens botten, m8jligg8r utpumpningen av -vattenoverskottet. A suction pipe 170, which opens out at the bottom of the cistern, enables the pumping out of the excess water.
Den ovan beskrivna anordningen maste naturligtvis vara sa inställd, att, sa lange hjalpspjallet 159 är oppet, dvs. sa lange vattenskiktet joke natt den h5gsta tillatna nivan, flottorarmen 15 under tappning ej skall kunna sankas sa langt, att dess tvarriir 51 nar in i vattenskiktet. Nedre gransen for flott5rarmens rOrelse bestammes av armen 131, dá denna slar an mot cisternens botten och darvid stanger spjallet 122 eller ett annat avstangningsorgan. Man maste darfor se till, att detta avstangningsorgan ãr stangt och flottorarmen avstannad omedelbart, innan tvarroret 51 nar vattennivan 171. The device described above must, of course, be set so that, as long as the auxiliary slat 159 is open, i.e. so long the water layer joke night the highest permissible level, the float arm 15 during bottling should not be able to sink so far that its transverse 51 reaches the water layer. The lower limit of movement of the float arm is determined by the arm 131, which strikes the bottom of the cistern and thereby closes the damper 122 or other shut-off member. Care must therefore be taken to ensure that this shut-off means is closed and that the raft arm is stopped immediately before the turret 51 reaches the water level 171.
Spjallen 122 och 159 tillforsakra sa.ledes oberoende av varandra avstangningen av ledningen, men deras funktioner aro °like.. Spj al-let tillfOrsakrar avstangningen endast, nar flottorarmen nar sitt nedre andlage vid lagre vattenniva an den tillatna grfinsnivan 171. Iljalpspjallet 159 daremot stanges endast, om denna gransniva nas, oberoende av vilket lige flott5rarmen intar, och saledes aven under pagaende fyllning, om det inpumpade branslet innehaller tillrackligt med vatten for att h5ja vattennivan till den tillatna gransen 171. Denna sakerhetsanordning indikerar saledes forefintligheten av [Sr stor vattenmangd i brans-let. Det Sr tydligt, att man till den beskrivna flottOren 169 kan ansluta ett organ for indikering av den iivre nivan av det i botten av cisternen samlade vattenskiktet, t. ex. en med flottoren forbunden, uppai genom manhalet ford stang, som pfiverkar en indikator. The dampers 122 and 159 thus independently secure the shut-off of the pipe, but their functions are similar. The damper causes the shut-off only when the float arm reaches its lower abutment at a lower water level than the permitted graphine level 171. The oil damper 159, on the other hand, is closed. only if this spruce level is reached, regardless of what the floating arm consumes, and thus also during pagan filling, if the pumped fuel contains enough water to raise the water level to the permitted limit 171. This safety device thus indicates the presence of [Sr large amount of water in industry-let. It is clear that a means for indicating the upper level of the water layer collected at the bottom of the cistern can be connected to the described float 169, e.g. one connected to the float, uppai through the manhalet ford rod, which pfiverkar an indicator.
