Abstract
Description
529 081 Rördelen 3, genom vilket ett medium är avsett att strömma, uppvisar ett krökt parti 5, som är beläget inne i eldstaden. Därvid bildar det krökta partiet 5 företrädesvis en trubbig vinkel med fördelen 3.Vid partiets 5 mynning är anordnad en rörfonnig hållare 6 för en rörstump 7, som uppvisar en förträngning 8 vid sin yttre del som fungerar som munstycke. Rörstumpen 7 är därvid fastskruvad på hållaren 6. Utanpå rör Stumpen 7 appliceras ett annat rör 8 som vid sin yttre del är förbunden med en spridarläpp 9. 529 081 The pipe part 3, through which a medium is intended to flow, has a curved portion 5, which is located inside the fireplace. In this case, the curved portion 5 preferably forms an obtuse angle with the advantage 3. At the mouth of the portion 5 a tubular holder 6 for a pipe stub 7 is arranged, which has a constriction 8 at its outer part which functions as a nozzle. The pipe stub 7 is then screwed onto the holder 6. On the outside of the pipe The stump 7 is applied to another pipe 8 which at its outer part is connected to a spreader lip 9.
En reglerkropp 10 fig.2, som är droppfonnad, är anordnad väsentligen axiellt förskjutbar relativt munstycket 6 7 8, varigenom flödesmängden genom munstyckets mynning kan regleras.A control body 10 fi g.2, which is drop-shaped, is arranged substantially axially displaceable relative to the nozzle 6 7 8, whereby the amount of fate through the mouth of the nozzle can be regulated.
Regleringskroppen 10 fig. 2, är anordnad vid främre delen av en stång 12, vars bakre del skjuter ut utanför röret 3 och är fastsatt vid en vinkel led 14 inne i eldstaden.Adjusting body 10 fi g. 2, is arranged at the front part of a rod 12, the rear part of which projects outside the pipe 3 and is fixed at an angle joint 14 inside the fireplace.
Vinkelleden är sålunda också placerad utanför röret 3 och är fastsatt på dennes ovansida.The angle joint is thus also placed outside the tube 3 and is attached to its upper side.
Vinkel leden 14 utgöres av led där stången 18 är fastsatt så att stången 12 kan röras axielltVidare är stången 18 i sin andra ende fastsatt i en styrmotor 21 som i sin tur är kopplad till en flödesmätare.The angle joint 14 consists of joints where the rod 18 is fixed so that the rod 12 can be moved axially. Furthermore, the rod 18 is at its other end fixed in a control motor 21 which in turn is connected to a speedometer.
Signalen från en flödesmätare går till regulator på operatörens dataskärm där denne kan ändra ett bör värde som sedan stynnotom arbetar mot.The signal from a fate meter goes to the controller on the operator's computer screen where he can change a setpoint value which the thin note then works towards.
För att förhindra att vinkelleden 14 och stången 12 med tillhörande hylsa 11 inte skall komma i kontakt med de alstrande gaserna inne i eldstaden och sålunda tilltörsäkra användaren god manöverbarhet, är vinkelleden med dess reglerfunktion skyddad av en skyddskåpa 13, och är fastsatt på röret 3 på ovansidan.In order to prevent the angle joint 14 and the rod 12 with associated sleeve 11 from coming into contact with the generating gases inside the fireplace and thus ensure the user good maneuverability, the angle joint with its control function is protected by a protective cover 13, and is attached to the tube 3 on the top.
Kåpans tvärsnitt uppvisar lämpligen formen av ett upp och ned vänt u, där ena gaveln på kåpan är täckt för att skydda dess regleranordning.The cross section of the cover suitably has the shape of an upside down u, where one end of the cover is covered to protect its control device.
För att inte skyddsmanteln 13 ska ßrstöras av förbränningen inne i pannan är den dubbelmantlad och ett lämpligt kyl medium texJuft tillföres genom ett rör 15 och tas ut via röret 16.To prevent the protective jacket 13 from being disturbed by the combustion inside the boiler, it is double-jacketed and a suitable cooling medium such as air is supplied through a pipe 15 and taken out via the pipe 16.
