Description
Foreliggende oppfinnelse angår en termostat og da særlig en termostat med en ekspanderbar masse anbragt i en stort sett stiv" innkapsling. The present invention relates to a thermostat and in particular a thermostat with an expandable mass placed in a largely rigid enclosure.
Ved termostater av denne type er det vanlig at den ekspanderbare massen er innelukket i en stiv, begerformet innkapsling. Da vil den ekspanderbare massen innta en form av en kompakt sylinder hvis overflate er relativt liten i forhold til dens volum. De vanlige ekspanderbare masser har en relativt lav termisk ledningsevne, og dette fører til at termostater bygget opp på denne måten far en stor tidsforsinkelse eller en langsom reaksjonshastighet slik at disse elementer vanligvis er dårlig egnet for sanitæranlegg og særlig for blandebatterier i slike anlegg. With thermostats of this type, it is common for the expandable mass to be enclosed in a rigid, cup-shaped enclosure. Then the expandable mass will take the form of a compact cylinder whose surface is relatively small in relation to its volume. The usual expandable masses have a relatively low thermal conductivity, and this leads to thermostats built in this way experiencing a large time delay or a slow reaction speed, so that these elements are usually not suitable for sanitary installations and especially for mixer taps in such installations.
For å unngå disse ulemper er det fra tysk patentsøknad nr. 24 41 224 kjent .å anbringe den ekspanderbare massen i et hul-legeme som er bégrenset av en indre og en ytre sylinder som står: i koaksialt inngrep med hverandre og danner en hul sylinder. In order to avoid these disadvantages, it is known from German patent application no. 24 41 224 to place the expandable mass in a hollow body which is bounded by an inner and an outer cylinder which are: in coaxial engagement with each other and form a hollow cylinder .
I overgangsområdet til membranen ér det innført hylser med gjennomgående åpninger som utgjør passasjer som forbinder rommet innenfor og utenfor hul-legemet med hverandre. En slik konstruksjon kan forbedre reaksjonstiden, men produksjonen og fyllingen av innkapslingen er vanskelig og derfor også kostbar. In the transition area to the membrane, sleeves with through openings are introduced which form passages that connect the space inside and outside the hollow body with each other. Such a construction can improve the reaction time, but the production and filling of the encapsulation is difficult and therefore also expensive.
Formålet med foreliggende oppfinnelse er derfor å tilveie-bringe en termostat som gir en kort reaksjonstid og som kan frem- "' stilles ved enkle midler. Dette oppnås ved å utføre termostaten i overensstemmelse med de nedenfor fremsatte patentkrav. The purpose of the present invention is therefore to provide a thermostat which gives a short reaction time and which can be produced by simple means. This is achieved by making the thermostat in accordance with the patent claims set out below.
Ved å utforme termostaten i overensstemmelse med foreliggende oppfinnelse, oppnås at den ekspanderbare massen, som f.eks. kan være voks, kan anbringes med optimal fordeling i forhold til overflaten til termostatens innkapsling slik at reaksjonstiden.til termostaten blir så kort at den er egnet f.eks. for'blanding av kaldt og varmt vann i blandebatteriér. By designing the thermostat in accordance with the present invention, it is achieved that the expandable mass, which e.g. can be wax, can be placed with optimal distribution in relation to the surface of the thermostat's enclosure so that the reaction time to the thermostat is so short that it is suitable e.g. for mixing cold and hot water in mixer taps.
Den enkle og rimelige konstruksjon av termostatens innkapsling, den enkle fyllingen méd' ekspanderbar masse og den enkle avluk5-ningen av innkapslingen, f.eks. v.hj.a. flens, alt sammen kjente og velprøvde metoder, kan opprettholdes. Fortréngningslegemet kan fremstilles med lave kostnader, f.eks. ved préss-støping av aluminium- eller sinklegeringer eller av en plast med liten termisk utvidelseskoeffisient. The simple and affordable construction of the thermostat's enclosure, the simple filling with expandable mass and the simple closing of the enclosure, e.g. v.hj.a. flange, all known and proven methods, can be maintained. The displacement body can be manufactured with low costs, e.g. by die-casting of aluminum or zinc alloys or of a plastic with a small coefficient of thermal expansion.
For å gi én klarere forståelse av foreliggende oppfinnelse vises til nedenstående detaljerte beskrivelse av et utførélses-eksempel, såmt til de ledsagende tegninger, hvor: To provide a clearer understanding of the present invention, reference is made to the detailed description below of an exemplary embodiment, together with the accompanying drawings, where:
Fig. 1 viser et termostatelement i lengdesnitt,Fig. 1 shows a thermostat element in longitudinal section,
Fig. 2 viser termostaten i henhold til fig. 1 snittet gjennom planet II. Fig. 2 shows the thermostat according to fig. 1 the section through plane II.
Termostatelementet består av en innkapsling 1 som i sin tur omfatter en begerformet bunndel 2 og en topp-plate 3, som omfatter en konsentrisk styring og fastholdelse for en trykkstift 5, en skive 6 og en membran 4. I den sylindriske bunndelen 2 er det anbragt et fortrengningslegeme 7 med avstandsribber 8 som gjør at selve hoveddelen av legemet 7 oppnår en liten klaring fra veggene til innkapslingen 1. Antallet avstandsribber 8 er 4, og de er tildannet på den sylindriske overflaten til fortréngningslegemet 7 og rager ut over endestykkene, men bare så mye at det tilsvarer en forutbestemt avstand mellom innkapslingen og hoveddelen av fortréngningslegemet 7, slik at fortréngningslegemet 7 både aksielt og radielt posisjoneres med liten avstand fra veggene til ! innkapslingen 1. Det.lille mellomrommet mellom innkapslingen 1 og fortréngningslegemet 7 fyiles med en ekspanderbar masse 9, f.eks. voks. Etter at den ekspanderbare massen er helt inn i mellomrommet og fortréngningslegemet 7 er anbragt i bunndelen og membranen er montert i toppdelen, blir de to seksjonene bragt sammen og forbindes med hverandré, f.eks. v.hj.a. konvensjonelle flenser, så dét oppstår en tett forsegling mellom flensen 10 og bunndelen 2. Dersom nå temperaturen forandrer seg i området som omgir termostaten'som er tildannet på denne måten, vil tempera-turforandringene overføres direkte til den ekspanderbaré massen 9,,. og overføringen vil være meget effektiv på grunn av den store overflaten som massen får på grunn av fortréngningslegemet 7. Overflaten til den ekspanderbare massen 9 blir meget stor i forhold til volumet, og temperaturendringer vil derfdir frembringe en hurtig forandring i volumet som fører til tilsvarende utbøy-* ninger av membranen 4 og dermed også til en forskyvning av trykk-stiften 5. The thermostat element consists of an enclosure 1 which in turn comprises a cup-shaped bottom part 2 and a top plate 3, which comprises a concentric guide and retention for a pressure pin 5, a disc 6 and a membrane 4. In the cylindrical bottom part 2 is placed a displacement body 7 with spacer ribs 8 which means that the main part of the body 7 itself achieves a small clearance from the walls of the enclosure 1. The number of spacer ribs 8 is 4, and they are formed on the cylindrical surface of the displacement body 7 and protrude above the end pieces, but only so much that it corresponds to a predetermined distance between the enclosure and the main part of the displacement body 7, so that the displacement body 7 is positioned both axially and radially with a small distance from the walls of the ! the enclosure 1. The small space between the enclosure 1 and the displacement body 7 is filled with an expandable mass 9, e.g. wax. After the expandable mass has completely entered the space and the displacement body 7 has been placed in the bottom part and the membrane has been mounted in the top part, the two sections are brought together and connected to each other, e.g. v.hj.a. conventional flanges, so a tight seal occurs between the flange 10 and the bottom part 2. If the temperature now changes in the area surrounding the thermostat, which is created in this way, the temperature changes will be transferred directly to the expandable mass 9,,. and the transfer will be very efficient due to the large surface that the mass gets due to the displacement body 7. The surface of the expandable mass 9 will be very large in relation to the volume, and temperature changes will therefore produce a rapid change in the volume which leads to a corresponding deflection -* nings of the membrane 4 and thus also to a displacement of the pressure pin 5.
Hvis membranen 4 er fremstilt av gummi eller et lignende fjærende, materiale, kan membranens ytre del også virke som en forsegling mellom topp- og bunndelen 2 henholdsvis 3 i området til flensens fremspring .10. Detter selvfølgelig også mulig å benytte en membran av metall istedenfor gummimembranen, og tetning kan da skje med konvensjonelle paknlngsringer eller toppdelen kan sveises til bunndelen. Fortréngningslegemet 7 kan; gjerne fremstilles ved press-støping av sink- eller aluminiums-legeringer eller av en plast med en lav termisk utvidelseskoeffisient. If the membrane 4 is made of rubber or a similar resilient material, the outer part of the membrane can also act as a seal between the top and bottom parts 2 and 3 respectively in the area of the flange's projection .10. Of course, it is also possible to use a metal membrane instead of the rubber membrane, and sealing can then be done with conventional packing rings or the top part can be welded to the bottom part. The displacement body 7 can; preferably produced by die-casting of zinc or aluminum alloys or of a plastic with a low coefficient of thermal expansion.
