Sprayhuvud Föreliggande uppfinning avser ett sprayhuvud med ett antal dysar för sprutande av vätskedinuna.Spray Head The present invention relates to a spray head having a plurality of nozzles for spraying the liquid sheet.

5 Tili exempel i fartygsmaskinrum kan alternativt förekonuna häftiga bränder, säsom oljebränder, eller rela-tivt smä bränder som ofta är pyrande bränder.For example, in ship engine rooms, alternative fires can occur, such as oil fires, or relatively small fires which are often fires.

För att släcka en häftig brand, t.ex. i en diesel-motor, fordras ätminstone inledningsvis en vätskedimsträle 10 med stark penetration, dvs. med förmäga att tränga genom uppstigande hetluft och rökgaser ned tili själva brandhär-den. Platsen för en eventuell häftig brand kan i allmänhet förutsägas med god sannolikhet, och erforderliga sprayhuvud kan placeras pä ändamälsenliga ställen.To extinguish a violent fire, e.g. in a diesel engine, at least initially a liquid penetration jet 10 with strong penetration, i.e. with the ability to penetrate through rising hot air and flue gases down to the hearth itself. The site of a potentially violent fire can generally be predicted with good probability, and the required spray heads can be placed at appropriate locations.

15 En liten, eventuellt pyrande brand kan däremot bry- ta ut nästan var som heist och en sädan brand kan säkrast släckas genom att fyllä hela utrymmet ifräga med finförde-lad vätskedinuna, säkallad "total flooding".15 On the other hand, a small, possibly bursting fire can break out almost anywhere as a heist and such a fire can be extinguished most safely by filling the entire space with finely divided liquid dinuna, called "total flooding".

Ändamälet med uppfinningen är att ästadkonuna ett 20 nytt sprayhuvud, som kan utnyttjas för att släcka säväl Stora, häftiga bränder som smä bränder.The object of the invention is to give the town woman a new spray head which can be used to extinguish both large, violent fires and small fires.

Sprayhuvudet enligt uppfinningen är i huvudsak kän-netecknat av att det uppvisar ätminstone en dys med förhällandevis stor dysöpp-25 ning, för att under högt vätskedrivtryck alstra en stark vätskedimsträle, ett flertal dysar med avsevärt mindre dysöppning, för att alstra en finfördelad vätskedinuna, och att nämnda ätminstone ena dys med förhällandevis 30 stor dysöppning är anordnad att av en spindel, som belas-täs av en fjäder i riktning emot vätsketrycket, tillslutas vid ett pä förhand bestämbart vätsketryck.The spray head according to the invention is characterized in that it has at least one nozzle with a relatively large nozzle opening, to produce a strong liquid mist jet, a plurality of nozzles with considerably smaller nozzle opening, under high fluid pressure, to produce a finely divided liquid nozzle. the said at least one nozzle having a relatively large nozzle opening is arranged to close a fluid pressure which is pre-determined by a spring loaded by a spring in the direction of the liquid pressure.

Företrädesvis har man ett flertal dysar med förhäl-landevis stor dysöppning, t.ex. tre stycken centralt i 35 sprayhuvudet, medan dysarna med avsevärt mindre dysöpp- 2 96174 ning, t.ex. nio stycken, lämpligen är anordnade perifert i en krans.Preferably, there are a plurality of nozzles with relatively large nozzle openings, e.g. three nozzles centrally in the spray head, while the nozzles with significantly smaller nozzle opening, e.g. nine, preferably arranged circumferentially in a wreath.

Dysarna med förhällandevis stor dysöppning kan vara anordnade att stänga sig vid ett vätsketryck av t.ex. 70 5 bar. Vid lägre vätsketryck sprutar säledes sprayhuvudet vätskedimma endast via dysarna med avsevärt mindre dysöppning, varvid man med fördel kan blanda in tilläggsgas i vätskedimmman, t.ex. i enlighet med vad som är angivet i patentansökningen 941738 eller 941975.The nozzles with relatively large nozzle apertures may be arranged to close at a liquid pressure of e.g. 70 5 bar. Thus, at lower liquid pressures, the spray head only sprays liquid mist through the nozzles with considerably smaller nozzle opening, whereby additional gas can be mixed into the liquid mist, e.g. in accordance with patent application 941738 or 941975.

10 Uppfinningen skall i det följande beskrivas mer i detalj med hänvisning tili ett pä bifogade ritning visat utföringsexempel.The invention will now be described in more detail with reference to an embodiment shown in the accompanying drawing.

Figur 1 visar ett sprayhuvud i längdsnitt.Figure 1 shows a longitudinal sectional spray head.

Figur 2 visar i större skala ett längdsnitt av en 15 dys med förhällandevis stor dysöppning, i öppet läge.Figure 2 shows on a larger scale a longitudinal section of a nozzle with a relatively large nozzle opening, in the open position.

Figur 3 visar likt figur 2 en dys med förhällande-vis stor dysöppning, i stängt tillständ.Figure 3, like Figure 2, shows a nozzle with a relatively large nozzle opening, in the closed state.

Sprayhuvudets hus 1 uppvisar en central inlopps-kanal 2 för släckvätska, vilken inloppskanal 2 via förgre-20 ningar 3 stär i förbindelse med i föreliggande ritnings-exempel nio stycken perifert i en krans anordnade dysar 4 med liten dysöppning, t.ex. 0,5 mm i diameter. Frän tre av förgreningarna 3 utgär en ytterligare förgrening 6, tili i föreliggande ritningsexempel sammanlagt tre stycken cent-25 ralt anordnade dysar 7 med förhällandevis stor dysöppning -1 8, t.ex. 1,5 mm i diameter.The spray head housing 1 has a central extinguishing fluid inlet channel 2, which inlet channel 2, through latches 3, stays in communication with nine of the periphery of the present drawing example, peripherally arranged in a ring nozzle 4 with a small nozzle opening, e.g. 0.5 mm in diameter. From three of the branches 3, an additional branch 6, in the present drawing example, comprises a total of three centrally arranged nozzles 7 with relatively large nozzle opening -18, e.g. 1.5 mm in diameter.

I företrädesvis varje inloppskanal 6 tili dysarna 7 med förhällandevis stor dysöppning 8 är anbragt en spindel med en hylslik del 9 öppen i sin ände emot kanalen 6 och 30 företrädesvis i tätt glidande anliggning emot kanalens 6 vägg, med minst en genomströmningsöppning 10 i hylsväggen, och med ett huvud 11, emot vilket anligger en fjäder 12, vars andra ände är stödd via ett filter 13 emot dysens 7 hus.Preferably in each inlet channel 6 of the nozzles 7 with relatively large nozzle opening 8 is arranged a spindle with a sleeve-like part 9 open at its end against the channel 6 and preferably in a tightly sliding abutment against the wall of the channel 6, with at least one throughflow opening 10 and the socket 10. with a head 11, against which abuts a spring 12, the other end of which is supported via a filter 13 against the housing of the nozzle 7.

Il < Ukit li· Il :<·«· '’ » m 3 96174 I figur 2 är vätsketrycket i kansien 6 sä stort, t.ex. 200 - 300 bar, att spindeln med sltt huvud 11 trycker ihop fjädern 12, sä att huvudets 11 skuldra 16 lösgör sig frän motsvarande anliggningsyta 17 i sprayhuvu-5 dets hus 1 och släckvätska kan strömma ut via öppningarna 10, ringrummet 18 mellan spindelhuvudet 11 och huset 1, genom filtret 13 och mellan (längs) omkring en tapp 14 lagd spiralfjäders 15 slingor 1 en spiralformad bana 19 och ut genom dysöppningen 8.In figure 2, the liquid pressure in chance 6 is great, e.g. 200-300 bar, that the spindle with closed head 11 compresses the spring 12, so that the shoulder 16 of the head 11 detaches from the corresponding abutment surface 17 in the spray head housing 1 and extinguishing liquid can flow out through the openings 10, the annular space 18 between the spindle head 11 and the housing 1, through the filter 13 and between (along) around the coils of a pin 14, coil spring 15, a helical path 19 and out through the nozzle opening 8.

10 I figur 3 har vätsketrycket i kanalen 6 sjunkit, t.ex. tili 70 bar, varvid fjädern 12 har övervunnit vätsketrycket och pressat spindelns huvud 11 tili tät anligg-ning emot huset 1 (ytorna 16 och 17), varvid vätskeförbin-delsen frän kanalen 6 tili dysöppningen 8 har blivit 15 stängd och vätska nu endast strömmar tili kransdysarna 4.In Figure 3, the fluid pressure in the duct 6 has dropped, e.g. to 70 bar, whereby the spring 12 has overcome the fluid pressure and pressed the head 11 of the spindle into a tight abutment against the housing 1 (the surfaces 16 and 17), the liquid connection from the channel 6 to the nozzle opening 8 being closed and liquid now only flowing to the the wreath nozzles 4.
