Abstract

Metallplate belagt med polymer og fremgangsmåte for fremstilling av denne.Metal plate coated with polymer and process for its manufacture.

Description

Anordning ved vannvarmer. Device at water heater.

Denne oppfinnelse vedrører en spe-' siell drosleventil som anbringes i rørfor-bindelsen mellom en beholder for varmt vann og det tilhørende ekspansjonskar. This invention relates to a special throttle valve which is placed in the pipe connection between a container for hot water and the associated expansion vessel.

En meget anvendt type vannvarmer har foruten selve trykkbeholderen for bruksvannet en ytre beholder med stillestående vann hvor varmeelementet er plasert. A widely used type of water heater has, in addition to the actual pressure vessel for the service water, an outer vessel with stagnant water where the heating element is placed.

Vannet i denne beholder har behov for et ytre ekspansjonskar til å oppta volum-forandringer ved temperaturvariasjoner i vannet. The water in this container needs an external expansion vessel to absorb volume changes due to temperature variations in the water.

Oftest sitter dette ekspansjonskar på toppen av vannvarmeren, forbundet med et kort rør for den ytre beholder. Most often, this expansion vessel sits on top of the water heater, connected by a short pipe to the outer container.

Dette rør må av sikkerhetshensyn, hvis koking skulle forekomme, ha et ganske stort tverrsnitt. For safety reasons, if boiling were to occur, this pipe must have a fairly large cross-section.

Dette medfører imidlertid at det oppstår en ikke ubetydelig, såkalt selvsirkula-sjon av vann mellom beholder og ekspansjonskar, ved at varmt vann fra beholderen finner veien opp i ekspansjonskaret, mens tilsvarende mengde kaldt vann strømmer ned i beholderen. However, this means that a not insignificant, so-called self-circulation of water occurs between the container and the expansion vessel, in that hot water from the container finds its way up into the expansion vessel, while a corresponding amount of cold water flows down into the container.

Det har lenge vært kjent at dette er uheldig. It has long been known that this is unfortunate.

Varmetapet blir større enn nødvendig og fordampningen og behovet for etterfyl-ling i ekspansjonskaret er stort på grunn av høy temperatur på vannet i ekspansjonskaret. The heat loss becomes greater than necessary and the evaporation and the need for top-up in the expansion vessel is great due to the high temperature of the water in the expansion vessel.

Ennå alvorligere er det at denne uøns-kede sirkulasjon av vann forkorter hele vannvarmerens levetid. Even more serious is that this unwanted circulation of water shortens the whole life of the water heater.

Det vann som strømmer ned fra eks- The water that flows down from ex-

pansjonskaret, har opptatt surstoff ved kontakt med luft, og dette ganske surstoff-holdige vann foranlediger øket korrosjon når det kommer ned i beholderen. the boarding vessel, has taken up oxygen on contact with air, and this rather oxygen-containing water causes increased corrosion when it gets into the container.

Den beskrevne oppfinnelse reduserer The described invention reduces

de her nevnte ulemper betraktelig. the disadvantages mentioned here considerably.

Ideen er bygget på å anbringe en spe-siell ventil i den korte rørforbindelse. Denne ventil er konstruert og utformet således at den ved normal drift, dvs. når vannet ved oppvarming eller avkjøling strømmer opp i eller ned fra ekspansjonskaret, slip-per igjennom dette vann, men heller ikke mere. The idea is based on placing a special valve in the short pipe connection. This valve is constructed and designed so that during normal operation, i.e. when the water during heating or cooling flows up into or down from the expansion tank, it lets this water through, but no more.

Ventilen har imidlertid også den egen-skap at den, hvis overoppheting og koking finner sted, gir fri avgang for vann eller damp så at overtrykk ikke oppstår. However, the valve also has the property that, if overheating and boiling takes place, it allows water or steam to escape freely so that overpressure does not occur.

Denne oppfinnelse er selvsagt også an-vendelig på vannvarmere av den type hvor trykkvannet ledes gjennom en kobberspi-ral anbrakt i det stillestående magasin-vann. This invention is of course also applicable to water heaters of the type where the pressurized water is led through a copper spiral placed in the stagnant reservoir water.

Tegningen viser to eksempler på hvor-dan ventilen kan konstrueres, men den kan også utformes på andre måter. Fig. 1 viser1 rent skjematisk en varmt-vannsbeholder av den type oppfinnelsen vedrører. Fig. 2, 2a og 3 viser detaljer ifølge oppfinnelsen vedrørende varmtvannsbe-holderen ifølge fig. 1. The drawing shows two examples of how the valve can be constructed, but it can also be designed in other ways. Fig. 1 shows schematically a hot water tank of the type to which the invention relates. Fig. 2, 2a and 3 show details according to the invention regarding the hot water container according to fig. 1.

Med 1 er betegnet den ytre vannbehol-der, i hvilken er anbrakt den indre trykk-tette beholder 2 med tilløp 3 og avløp 4. I beholderen 1 er anbrakt varmeelementer 5, og på toppen av beholderen er der anordnet et ekspansjonskar 6, forbundet med beholderen 1 ved en rørstuss 7. 1 denotes the outer water container, in which is placed the inner pressure-tight container 2 with inlet 3 and drain 4. Heating elements 5 are placed in the container 1, and an expansion vessel 6 is arranged on top of the container, connected with the container 1 at a pipe connection 7.

Det er i overgangen mellom beholderen 1 og ekspansjonskaret 6 at oppfinnelsen kommer til anvendelse. Dette område er på fig. 1 innsirklet med strekprikkede linjer. Fig. 2 viser dette område i snitt i større målestokk og forsynt med en ventilanord-ning ifølge oppfinnelsen. Mellom ekspan-sjonskarets 6 bunn og rørstussen 7 er anordnet en gjenget hylse 8 for fastholdelse av en ventilskive 9 av elastisk materiale. Ventilskiven 9 er forsynt med et sentralt lite hull 10 samt har oppslissinger 11. Ved vanlig ekspansjon og konstruksjon av vannet i beholderen 1 er hullet 10 tilstrekkelig stort for den nødvendige forbindelse. Ved overoppvarming eller koking kan imidlertid den elastiske ventilskive 9 gi etter ved at flikene som dannes ved oppslissingene 11, bøyes ut som antydet ved 9', hvorved en vesentlig større passasje fåes mellom be holderen 1 og ekspansjonskaret. Fig. 2a viser selve den oppslissete ventilskive sett i plan. Fig. 3 viser en modifisert utførelse av en ventil ifølge oppfinnelsen. På toppen av forbindelsesrøret 7 er her anordnet en konisk ventil 12 med et lite hull 13. Ventilen 12 er vektbelastet som antydet ved 14. Det lille hull 13 gir tilstrekkelig forbindelse under vanlige forhold. Ved koking vil imidlertid hele ventilen 12 kunne løftes opp mot virkningen av vekten 14 og derved gi tilstrekkelig passasje. It is in the transition between the container 1 and the expansion vessel 6 that the invention comes into use. This area is in fig. 1 circled with dotted lines. Fig. 2 shows this area in section on a larger scale and equipped with a valve device according to the invention. Between the bottom of the expansion vessel 6 and the pipe connection 7, a threaded sleeve 8 is arranged for retaining a valve disk 9 of elastic material. The valve disk 9 is provided with a central small hole 10 and has slits 11. In the case of normal expansion and construction of the water in the container 1, the hole 10 is sufficiently large for the necessary connection. In the event of overheating or boiling, however, the elastic valve disk 9 can yield when the tabs formed by the slits 11 are bent out as indicated at 9', whereby a significantly larger passage is obtained between the container 1 and the expansion vessel. Fig. 2a shows the slotted valve disc itself seen in plan. Fig. 3 shows a modified version of a valve according to the invention. A conical valve 12 with a small hole 13 is arranged on top of the connecting pipe 7. The valve 12 is weight-loaded as indicated at 14. The small hole 13 provides a sufficient connection under normal conditions. When boiling, however, the entire valve 12 will be able to be lifted up against the action of the weight 14 and thereby provide sufficient passage.

Det vil forstås at de viste ventilutfø-relser ifølge fig. 2 og 3 bare er eksempler på hvorledes slike ventiler kan utføres og at en rekke variasjoner er mulig innenfor rammen av den idé som ligger til grunn for oppfinnelsen. It will be understood that the valve designs shown according to fig. 2 and 3 are only examples of how such valves can be made and that a number of variations are possible within the scope of the idea underlying the invention.
