Description
Returvann-blandeventil for varmtvannsvarmeanlegg. Return water mixing valve for hot water heating systems.
Returvann-blandeventiler eller blandeventiler anvendes i varmtvannsvarmeanlegg til regulering av vannets tempera-tur, f. eks. når vanntemperaturen i varmekjelen eller i berederen overstiger den som skal holdes i varmtvannsledningsnettet. Reguleringen kan utføres ved hjelp av et antall vanlige reguleringsorganer eller ved hjelp av en kompakt enhet i form av en blandeinnretning. Return water mixing valves or mixing valves are used in hot water heating systems to regulate the water temperature, e.g. when the water temperature in the boiler or in the boiler exceeds that which must be maintained in the hot water mains. The regulation can be carried out with the help of a number of common regulation means or with the help of a compact unit in the form of a mixing device.
Så lenge det var vanlig å lede returvannet fra varmtvannsledningen ned til oppvarmningskjelens nederste del, var det tilstrekkelig til dette formål å anvende blandeventiler ved hvilke i det minste to porter ble åpnet henholdsvis lukket for styring av blandingsforholdet. Slike ventiler har en forholdsvis enkel konstruk-sjon og er derfor tilsvarende billige i an-skaffelse. As long as it was common to lead the return water from the hot water line down to the bottom part of the heating boiler, it was sufficient for this purpose to use mixing valves by which at least two ports were opened and closed respectively to control the mixing ratio. Such valves have a relatively simple construction and are therefore correspondingly cheap to purchase.
Etter at det er blitt til vanlig praksis After it has become common practice
å legge returledningen i samme eller stort sett samme høyde som turledningen, er de nevnte ventiler ikke lenger anvendelige. Hvis en slik ventil, f. eks. utført i henhold til fig. 1, monteres direkte på en varmekjel som er forsynt med i et felles plan liggende koblingsstusser tilsvarende stussene 1 og 2, vil følgende ulemper oppstå. to lay the return line at the same or largely the same height as the flow line, the aforementioned valves are no longer applicable. If such a valve, e.g. carried out according to fig. 1, is mounted directly on a boiler which is equipped with connecting sockets lying in a common plane corresponding to sockets 1 and 2, the following disadvantages will occur.
Under forutsetning av at returvannet Provided that the return water
går inn gjennom innløpsstussen 3 og ved en hensiktsmessig innstilling av ventilen skal ledes over til utløpsstussen 4 uten at det er meningen å tilblande opphetet vann, vil der oppstå en motstrøm i kjelens tilkoblingsstuss 1. Gjennom det like store rørtverrsnitts øvre del vil der da av kjente årsaker strømme vann fra den varme kjel inn i varmeledningen, mens en tilsvarende enters through the inlet nozzle 3 and, with an appropriate setting of the valve, is to be led over to the outlet nozzle 4 without the intention of mixing in heated water, a counterflow will occur in the boiler's connection nozzle 1. Through the upper part of the same large pipe cross-section, there will then, of known causes water to flow from the hot boiler into the heating pipe, while a corresponding
stor vannmengde vil føres gjennom tverr-snittets nedre del tilbake til kjelen, slik at det til tross for stengt ventil vil oppstå en temperaturøkning i det turvann som strømmer ut i varmeledningsnettet. a large amount of water will be led through the lower part of the cross-section back to the boiler, so that despite the closed valve there will be a temperature increase in the circulating water that flows out into the heating network.
I henhold til det som er forklart oven-for, vil samme forhold oppstå hvis man ved en annen anordning flytter reguleringsorganet 5 fra kjelens tilkoblingsstuss 2 til tilkoblingsstussen 1. Heller ikke i dette til-felle kan den uønskede tilblanding unn-gåes. In accordance with what has been explained above, the same situation will occur if, by means of another device, the regulating member 5 is moved from the boiler's connection socket 2 to the connection socket 1. Even in this case, the unwanted admixture cannot be avoided.
I henhold til oppfinnelsen er der imid-lertid skaffet en blandingsventil, i hvilken ventilstyringen bare foregår i to porter, idet dannnelsen av en motstrøm hindres ved en hensiktsmessig, sifongaktig utform-ning av ventilkanalen. According to the invention, however, a mixing valve has been provided, in which the valve control only takes place in two ports, the formation of a counterflow being prevented by an appropriate, siphon-like design of the valve channel.
Hensikten med oppfinnelsen er således å tilveiebringe en returvann-blandeventil for varmtvannsvarmeanlegg som har to kjeltilkoblingssteder og to tilkoblingsstusser som skal forbindes med rørlednings-nettet og som er forsynt med et reguleringsorgan ved hjelp av hvilket gjennom-strømningstverrsnittet mellom ventilens to over hinannen liggende porter reguleres som utmerker seg ved at der i blandeventilens kanal som skal forbindes med var-mekj elen og i hvilken en uønsket motstrøm vil dannes når reguleringsorganet inntar en bestemt stilling, og i den tilsvarende tilkoblingsstuss som skal forbindes med rør-ledningsnettet, er anordnet en skillevegg som hindrer at der dannes en slik mot-strømning. The purpose of the invention is thus to provide a return water mixing valve for hot water heating systems which has two boiler connection points and two connection spigots to be connected to the pipeline network and which is provided with a regulating device by means of which the through-flow cross-section between the valve's two overlapping ports is regulated as is distinguished by the fact that in the channel of the mixing valve which is to be connected to the boiler and in which an unwanted countercurrent will form when the regulating body takes a certain position, and in the corresponding connection piece which is to be connected to the pipeline network, a partition is arranged which prevents that such a counter-flow is formed.
Oppfinnelsen skal forklares ved to ut-førelseseksempler under henvisning til teg-ningen, hvor det av fig. 2 fremgår at en skillevegg 6 er anordnet mellom stussene 1 og 4. The invention shall be explained by means of two exemplary embodiments with reference to the drawing, where it is shown from fig. 2 shows that a partition wall 6 is arranged between the spigots 1 and 4.
Som følge av at koldt vann vil samle seg i det frie rom under varmt vann, opp-nåes ved hjelp av skilleveggen 6 at koldt vann fra blandeventilen ikke kan strømme inn i kjelen, og opphetet vann ikke kan strømme gjennom blandeventilen inn i turledningen. As a result of the fact that cold water will collect in the free space under hot water, it is achieved by means of the partition wall 6 that cold water from the mixing valve cannot flow into the boiler, and heated water cannot flow through the mixing valve into the flow line.
For å gjøre ventilen lettere, både med hensyn til vekt og bearbeidelse under fremstillingen, kan kjeltilkoblingsåpnin-gen 1 og 2 utformes som vist på fig. 3, idet de munner ut i en eneste flens 7, hvorved også befestigelsen av ventilen til kjelen blir enklere å utføre. Særlig ved stålplate-kjeler er det vanlig at motflensene for stussene 1 og 2 må sveises på, hvilket er en kilde til sveisespenninger som igjen kan bevirke at flensforbindelsen er vanskelig å få tett og krever ekstra avrettingsarbeide. Disse vanskeligheter er meget lettere å overkomme når blandeventilen bare er ut-styrt med en eneste flens for begge løp, som vist på fig. 3. Ventilen er dessuten lettere å montere på en kjel som er utført av stålplater. In order to make the valve lighter, both with regard to weight and processing during manufacture, the boiler connection opening 1 and 2 can be designed as shown in fig. 3, as they open into a single flange 7, whereby also the attachment of the valve to the boiler becomes easier to carry out. Particularly with steel plate boilers, it is common that the counter flanges for the spigots 1 and 2 have to be welded on, which is a source of welding stresses which in turn can cause the flange connection to be difficult to seal and requires additional leveling work. These difficulties are much easier to overcome when the mixing valve is only equipped with a single flange for both runs, as shown in fig. 3. The valve is also easier to mount on a boiler made of steel plates.
