Abstract
Description
511 559 centrum och i ett första läge är spjällbladet stängt och efter vridning av detta en förutbestämd vinkel befinner sig spjällbladet i ett maximalt öppet läge. Tack vare den tilluftsventilen kompletterande termostatkassetten kan denna första reglering av spjällbladet åstadkommas auto- matiskt. Från det öppna läget kan spjällbladet manuellt vridas ytterligare en förutbestämd vinkel till ett helt stängt läge utan påverkan av termostatstyrningen. 511 559 center and in a first position the damper blade is closed and after rotation of this a predetermined angle is located the damper blade in a maximum open position. Thanks to it the supply air valve supplementary thermostat cartridge can this first regulation of the damper blade is achieved automatically matically. From the open position, the damper blade can manually turn another predetermined angle into a whole closed position without the influence of the thermostat control.
Spjällbladets manuella manövrering sker med hjälp av kugg- hjul och en självrensande kuggstång, varigenom smuts, fett och dylikt, som annars lätt fastnar i ventilen, icke hind- rar spjällets reglering.The manual operation of the damper blade is done by means of wheels and a self-cleaning rack, whereby dirt, grease and the like, which otherwise easily get stuck in the valve, do not regulates the damper.
Uppfinningen beskrivs närmare nedan med hjälp av ett före- draget utföringsexempel under hänvisning till bifogade ritningar, på vilka fig. 1 visar en schematisk perspektivvy snett bakifrån av en tilluftsventil enligt uppfinningen med en ter- mostatkassett monterad vid spjällbladet, fig. 2 visar den i fig. 1 avbildade ventilen i en schema- tisk perspektivvy från andra hållet, fig. 3 visar en sprängvy av tilluftsventilen enligt fig. 1 och 2, av vilken framgår, hur de olika ingående delarna är monterade i förhållande till varandra, och fig. 4 visar en schematisk sprängvy i perspektiv sett från andra hållet än vad som är fallet i fig. 3 med de olika delarna i ventilen isärlagda och då särskilt termostatkassetten.The invention is described in more detail below with the aid of a drawn embodiments with reference to the appended drawings, on which Fig. 1 shows a schematic perspective view obliquely from behind from behind a supply air valve according to the invention with a mustat cassette mounted at the damper blade, Fig. 2 shows the valve shown in Fig. 1 in a schematic political perspective from the other side, Fig. 3 shows an exploded view of the supply air valve according to fig. 1 and 2, which show how the different components the parts are mounted in relation to each other, and Fig. 4 shows a schematic exploded view in perspective from the other side than is the case in Fig. 3 with the various parts of the valve disassembled and then especially the thermostat cartridge.
Såsom framgår av ritningarna, utgörs en föredragen ut- föringsform av en tilluftsventil 1 enligt föreliggande 3 511 559 uppfinningen av ett spjällhus 2 med ett däri vridbart monterat spjällblad 3. Tilluftsventilen 1 är enligt det föredragna exemplet utförd så, att spjällbladet 3 är fjä- derförspänt medelst en på ritningen icke visad skruvfjäder i riktning mot sitt stängda, första läge, vilket visas i fig. 1 och 2.As can be seen from the drawings, a preferred embodiment is embodiment of a supply air valve 1 according to the present 3 511 559 the invention of a throttle body 2 with a rotatable therein mounted damper blade 3. The supply air valve 1 is according to it preferred example is designed so that the damper blade 3 is pre-tensioned by means of a helical spring (not shown in the drawing) in the direction of its closed, first position, which is shown in Figs. 1 and 2.
Från detta första, helt stängda läge är spjällbladet 3 vridbart en förutbestämd vinkel till ett öppet läge med hjälp av en vid spjällbladet 3 monterbar termostatkassett 4. Från det öppna läget, till vilket spjällbladet 3 vridits med hjälp av termostatkassetten 4, kan sedan, om så önskas, spjällbladet 3 stängas manuellt genom att detta ytterligare vrids en förutbestämd vinkel till ett andra helt stängt läge. Den manuella manövreringen av spjällbladet 3 sker via en^spak_19 med hjälp av minst ett mot en kuggstång 5 ver- kande kugghjul 6; 7, som i sin tur påverkar spjällbladets 3 vridning. Kuggstången 5 utgörs i det visade exemplet av en slitsförsedd platta 8, vars slitsar 9 är rektangulära i och för samverkan med kuggstångens 5 slitsar 9. Genom denna utformning av kuggstången 5 blir densamma självrensande från fett, smuts och dylikt.From this first, completely closed position, the damper blade is 3 rotatable a predetermined angle to an open position with using a thermostat cassette mountable at the damper blade 3 4. From the open position, to which the damper blade 3 has been turned by means of the thermostat cassette 4, can then, if desired, the damper blade 3 is closed manually by this further turn a predetermined angle to a second completely closed location. The manual operation of the damper blade 3 takes place via a lever_19 by means of at least one against a rack 5 ver- pitcher gear 6; 7, which in turn affects the damper blade 3 twist. In the example shown, the rack 5 consists of one slotted plate 8, the slits 9 of which are rectangular in and for co-operation with the slots 9 of the rack 5 design of the rack 5 becomes the same self-cleaning from grease, dirt and the like.
För termostatkassettens 4 lägesfixering uppvisar spjäll- bladet 3 en centralt belägen urtagning 10, i vilken termo- statkassetten 4 är lägesfixerbar med ett enkelt handgrepp.For the position fixation of the thermostat cassette 4, the damper blade 3 a centrally located recess 10, in which thermo- the state cassette 4 is position-fixable with a simple grip.
Termostatkassettens 4 utgående vridaxel 11 rör sig i bero- ende av påverkan från en utomhustemperaturen avkännande känselkropp 12 och denna vridaxel 11 påverkar i sin tur spjällbladets 3 reglering. Termostatkassetten 4 innefattar förutom känselkroppen 12 en styrhylsa 16 med omslutande skruvfjäder 17 och ett vriddon 13, som uppvisar två motsatt belägna, snedskurna avsatser 14, 15, vilka överför känsel- kroppens 12 linjära rörelse till en vridrörelse och vilka delar hålls ihop av ett bygelelement 20. Vridrörelsen överförs således från vriddonet 13 till det underliggande spjällhuset 2 för spjällbladets 3 vridning. 511 559 Det kugghjul 6 som befinner sig under termostatkassetten 4 uppvisar ett flertal efter varandra anordnade kuggar 18 över endast sin i huvudsak halva omkrets motsvarande den vridning av spjällbladet vilken sker manuellt.The output rotary shaft 11 of the thermostat cassette 4 moves in end of the impact of an outdoor temperature sensing sensor body 12 and this rotary shaft 11 in turn actuate throttle blade 3 regulation. The thermostat cartridge 4 includes in addition to the sensing body 12, a guide sleeve 16 with enclosure coil spring 17 and a knob 13, which have two opposite located, sloping ledges 14, 15, which transmit emotional the linear movement of the body 12 to a rotational movement and which parts are held together by a stirrup element 20. The rotational movement is thus transferred from the rotary device 13 to the underlying the damper housing 2 for the rotation of the damper blade 3. 511 559 The gear 6 located under the thermostat cassette 4 has a plurality of successively arranged teeth 18 over only its substantially half circumference corresponding to it rotation of the damper blade which is done manually.
Tilluftsventilen 1 enligt uppfinningen fungerar på följande sätt. I det fall spjällbladet 3 försetts med en termostat- kassett 4, sker en automatisk reglering de första 70-90° efter utomhustemperaturen under spjällbladets 3 första öppningsfas från stängt till öppet läge. Härefter kan en manuell stängning av spjällbladet 3 ske genom vridning ytterligare en förutbestämd vinkel till cirka 140-180°. I det fall en termostatkassett 4 ännu icke monterats vid spjällbladet 3, genomförs öppning och stängning av ventilen 1 endast manuellt och då över ett område, som befinner sig över spjällbladets 3 andra öppningsfas från öppet till stängt läge och åter.The supply air valve 1 according to the invention operates on the following way. In the event that the damper blade 3 is provided with a thermostat cassette 4, an automatic adjustment takes place the first 70-90 ° after the outdoor temperature below the damper blade 3 first opening phase from closed to open position. Hereafter one can manual closing of the damper blade 3 is done by turning another predetermined angle to about 140-180 °. IN in case a thermostat cassette 4 has not yet been mounted throttle blade 3, opening and closing of the valve is performed 1 only manually and then over an area, which is located over the second opening phase of the damper blade 3 from open to closed mode and again.
