Abstract

The intention of the present invention is to design a reliably operating nozzle which would also enable generation of fog - especially of water fog - in quantities high enough for the needs of firefighting, where the size of water droplets in thus created fog should be as small as possible and possibly also variable or even adjustable in advance, while the shape of the jet of the outcoming fog should be of such a kind that the fog generated would occupy the space in front of the nozzle to the greatest possible extent. The nozzle consists of a housing (1) and a head (2) arranged coaxially one along another, where the head (2) is attached to the housing (1) mentioned by means of a bolt (3). Between the housing (1) and the head (2) of the nozzle, aligned coaxially and pressed against each other, a splitting element of the basic splitting assembly (23) is clamped and is aligned coaxially with the housing (1) and the head (2) too. The nozzle can comprise also an additional splitting assembly (5) which is arranged in the plane of the splitting element (23) already mentioned, yet out of the area of the head (2) or the housing (1) of the nozzle respectively.

Description

Šoba, zlasti za tvorbo megleNozzle, especially for mist formation

Pričujoči izum se nanaša na šobo, ki je namenjena tvorbi megle oz. zamegljevanju, še zlasti tvorbi vodne megle, ki je uporabna npr. pri gašenju požarov.The present invention relates to a nozzle which is intended for the formation of fog. blurring, in particular the formation of water mist, which is useful e.g. when extinguishing fires.

Izum temelji na problemu, kako zasnovati zanesljivo delujočo šobo, ki naj bi omogočala ustvarjanje tudi za potrebe gašenja požarov zadostnih količin megle, zlasti vodne megle, pri čemer naj bi bila velikost vodnih kapljic v tako ustvarjeni megli karseda majhna in po možnosti spremenljiva, zlasti vnaprej določljiva, oblika curka iztekajoče megle pa naj bi bila takšna, da bi ustvarjena megla v kar naj večji meri zapolnjevala prostor pred šobo.The invention is based on the problem of how to design a reliable working nozzle, which is also intended to create sufficient fog volumes, especially water fog, for the purpose of extinguishing fires, whereby the size of water droplets in the fog created in this way is as small and possibly variable as possible, especially in advance. The fog jets are determinable, and the flow pattern of the fog should be such that the fog created will fill the space in front of the nozzle as much as possible.

Znano je, da za potrebe učinkovitega gašenja požarov uporabljajo tudi vodno meglo, t.j. meglo, ki jo ustvarijo z razbitjem vodnega curka na drobne vodne kapljice. Megla je kot sredstvo za gašenje požarov primerna celo za gašenje požarov, ki so posledica gorenja naftnih derivatov ali drugih vnetljivih kemikalij ali tudi npr. električnih napeljav s pripadajočimi napravami. Se zlasti je megla zelo primerna za gašenje požarov v predorih, rudnikih in podobnih zaprtih prostorih, kjer je ogromno storjenega že zgolj z lokalizacijo požara do te mere, daje dostop z drugimi morda še učinkovitejšimi sredstvi sploh mogoč. K temu velja pridati še ugotovitev, daje megla ekološko povsem neoporečno sredstvo za gašenje požarov.Water fog is also known to be used for effective fire fighting, i.e. mist created by breaking the water jet into tiny water droplets. Fog is suitable as a fire extinguisher even for extinguishing fires caused by the burning of petroleum products or other flammable chemicals, or e.g. electrical wiring with associated devices. In particular, the fog is well suited for extinguishing fires in tunnels, mines and similar enclosures where much has already been done by localizing the fire to such an extent that access by other, perhaps even more effective means, is even possible. Another point to note is that fog is an environmentally friendly fire extinguisher.

Meglo je mogoče ustvariti s pomočjo šobe, ki je priključena na primemo sredstvo za dovod vode pod razmeroma visokim tlakom, ki znaša vsaj nekaj deset barov. Pri tem je treba posebej opozoriti, da pri tvorbi megle za gašenje požarov ne pride v poštev nikakršno dovajanje zraka, npr. zaradi učinkovitejšega razbijanja kapljic.The fog can be created by means of a nozzle connected to a suitable means of supplying water at a relatively high pressure of at least a few tens of bars. It should be noted in particular that no air intake is required when forming a fire extinguishing mist, e.g. for more efficient droplet breaking.

Znanih je več rešitev šob za ustvarjanje megle. Pri najširše uporabljanih šobah prijavitelju neznanega izvora gre za rešitev, pri kateri je v ohišju šobe na voljo konusna votlina, ki je na vrhu oz. na čelni ploskvi opremljena s skoznjo luknjo razmeroma majhnega premera, namreč bistveno manj kot 1 mm. V omenjeno votlino je vstavljen konusni nastavek, ki se oži v smeri od priključnega območja šobe, ki služi za povezavo s cevovodom, proti omenjeni skoznji luknji. Vodni curek, ki iz cevovoda vstopa v notranjost šobe, se v območju konusnega nastavka zavrti po njegovi površini, pri čemer se ob pomikanju proti skoznji luknji giblje po vse manjšem premeru in z vse večjo hitrostjo. Ob prehodu skozi skoznjo odprtino se curek razleti na drobne kapljice, katerih velikost pri dovolj majhnem premeru luknje lahko znaša pod 100 pm. Tolikšna velikost sicer ni čisto zadovoljiva, ker so pri zamegljevanju zaželene še manjše kapljice. Razen tega megla iz šobe izstopa v vsaj približno koničnem curku, kije tudi razmeroma ozek oz. vitek. To pomeni, da pri gašenju požara curek vodne megle učinkuje v območju pred šobo oz. pred gasilcem, medtem ko sosednjih območij, kjer se konec koncev nahaja tudi gasilec sam, učinek megle ne doseže. Če predpostavimo, daje pozornost gasilca usmerjena predvsem v območje, kamor prši curek megle, je očitno, da je med gašenjem gasilec razmeroma močno izpostavljen možnosti, da celo njega samega zajame ogenj ne le od zadaj, marveč celo od strani. Po drugi strani pa je tovrstna šoba še bolj problematična z vidika zanesljivosti delovanja. Že en sam drobec nečistoče, vodni kamen ali podobni pri vodi čisto vsakdanji pojavi lahko z zamašitvijo skoznje luknje povsem onesposobijo šobo oz. prekinejo njeno delovanje. Očitno je, daje to še posebej pri gašenju požarov zelo neprijetno in nevarno, in zato v večini primerov docela nesprejemljivo. Če bi kot prednost te rešitve lahko navedli npr. dejstvo, da je mogoče kvaliteto megle oz. velikost kapljic spreminjati s spreminjanjem tlaka dotekajoče vode, je po drugi strani spet prisotna še nadaljnja velika pomanjkljivost, in sicer ta, daje pretok omejen na vsega približno 1 1/min, kar za gašenje požarov večjih razsežnosti niti približno ne zadostuje.Several fog nozzle solutions are known. The most widely used nozzles for the applicant of unknown origin is a solution in which a conical cavity is available in the nozzle body, which is located at the top or top. fitted with a relatively small diameter through the hole, substantially less than 1 mm in diameter. A conical nozzle is inserted into said cavity, which narrows in the direction from the connecting area of the nozzle, which is used to connect the pipeline to the said through hole. The water jet entering the nozzle from the pipeline rotates over its surface in the area of the conical nozzle, moving at a smaller diameter and increasing speed as it moves through the hole. When passing through the aperture, the jet spills into tiny droplets, the size of which, at a sufficiently small hole diameter, can be below 100 pm. This size is not quite satisfactory, though, since smaller droplets are desirable when blurring. In addition, the fog from the nozzle stands out in at least approximately a conical jet, which is also relatively narrow or. slim. This means that when a fire is extinguished, a jet of water fog has an effect in the area in front of the nozzle. in front of the firefighter, while the adjacent areas, where the firefighter himself is located, does not achieve the fog effect. Assuming that the firefighter's attention is directed primarily to the area where the jet of fog is sprayed, it is obvious that during the extinguishing process, the firefighter is relatively heavily exposed to the possibility of him even catching fire not only from behind, but even from the side. On the other hand, this kind of nozzle is even more problematic in terms of reliability of operation. Just a single slice of dirt, scale, or similar everyday occurrences of water can completely nozzle through the hole through the hole. they interrupt its operation. Obviously, this is especially uncomfortable and dangerous in the case of fire fighting, and is therefore completely unacceptable in most cases. If the advantage of this solution could be cited e.g. the fact that the quality of the fog is possible. varying the size of the droplets by varying the pressure of the flowing water, on the other hand, there is again another major drawback, namely that the flow rate is limited to only about 1 1 / min, which is not nearly enough to extinguish large-scale fires.

Pri drugi prijavitelju znani rešitvi gre za šobo, katere ohišje je znotraj cilindrično in zaključeno s široko razprto konično čelno ploskvijo, na vrhu katere je spet na voljo skoznja luknja oz. izstopna odprtina. Tovrstna šoba opremljena z iglo, ki je nameščena izven ohišja, in sicer soosno z njegovo notranjo konfiguracijo kot tudi z omenjeno izstopno odprtino. Vodni curek, ki pod visokim tlakom izstopa skozi izstopno odprtino, takoj po izstopu trču v omenjeno iglo, na kateri se razcepi na drobne kapljice, hkrati pa se tok preusmeri v obliko konusa. Dasiravno je v tem primeru verjetno lažje preprečiti zamašitev šobe, gre tudi pri tej šobi za vrsto pomanjkljivosti, ki so enake tistim pri predhodno opisani rešitvi.Another solution known to the applicant is a nozzle whose housing is cylindrical inside and terminated by a wide open conical face, at the top of which again a hole or a hole is available. exit outlet. A nozzle of this type is provided with a needle mounted outside the housing, coaxially with its internal configuration as well as with said outlet port. A high-pressure water jet which exits through the outlet, immediately after exit, collides into said needle, where it splits into tiny droplets, at the same time diverting the flow into a cone shape. In this case, it is probably easier to prevent the nozzle from clogging, and this nozzle also has a number of disadvantages which are the same as those of the previously described solution.

Pri še nadalnji rešitvi šobe je ta tako izvedena, da curek dotekajoče vode vodijo skozi razmeroma dolgo luknjo majhnega premera, nakakšno kapilaro. Na izstopu je na voljo divergentno konično območje, na odmiku od izstopa iz omenjene kapilare pa je na voljo takoimenovan žebelj, namreč podolgovat vitek in še zlasti nekoničasto oz. topo zaključen element. Iz omenjene kapilare dotekajoči tenek vodni curek trči v čelno površino omenjenega žeblja, kjer se razprši oz. razbije na majhne vodnje kaplje, s čimer se v divergentnem koničnem območju in vzdolž omenjenega žeblja ustvarja megla. V tem primeru gre lahko za razmeroma ustrezno oblikovan curek izstopajoče megle. Curek namreč ni koničen, marveč ima obliko približno rotacijskega paraboloida, kar pomeni, da je npr. pri gašenju požarov z učinkom megle mogoče računati tudi v območju neposredno ob šobi oz. v območju, kjer se nahaja gasilec. Zal pa prav izmere omenjene kapilare omejujejo pretok vode skozi šobo na vsega približno 6 1/h oz. 0,1 1/min, kar je za resno gašenje požarov spet občutno premalo. Podobna rešitev s približno enakimi pomanjkljivostmi je opisana tudi v PCT/N094/00214 (WO 95/17926).In the further solution of the nozzle, the nozzle is so designed that the jet of flowing water is led through a relatively long hole of small diameter, such as a capillary. A divergent conical region is available at the exit, and at the distance from the exit from the aforementioned capillary there is a so-called nail, namely an elongated slim, and especially a non-conical or. a finely finished element. From the said capillary, a flowing thin water jet collides into the front surface of said nail, where it is dispersed or. it breaks into small water droplets, creating mist in the divergent conical region and along said nail. In this case, it may be a relatively well-designed jet of prominent fog. The turkey is not conical, but rather has the shape of an approximately rotary paraboloid, which means that, e.g. fog-extinguishing fires can also be counted in the area immediately adjacent to the nozzle or. in the area where the firefighter is located. Unfortunately, it is precisely the dimensions of said capillary that limit the flow of water through the nozzle to only about 6 1 / h or. 0.1 1 / min, which is again significantly insufficient for serious fire fighting. A similar solution with approximately the same disadvantages is also described in PCT / N094 / 00214 (WO 95/17926).

Nalje je iz PCT/SE95/00007 (WO 95/18651) znana šoba za razprševanje vodne megle, ki sestoji iz ohišja oz. priključka za povezavo s dovodno napeljavo, kot tudi iz glave, ki je soosno vstavljena v omenjeno ohišje. Ohišje je na izstopnem delu opremljeno s konusno površino, na kateri nalega prav tako s konusno površino opremljena glava šobe. Na konusni površini glave šobe so na voljo cikcakasto razporejeni kanali oz. izpusti, v katere vstopa voda iz notranjosti ohišja pod tlakom približno 200 bar. Po dva in dva sosednja kanala konvergirata drug proti drugemu, tako da se zahvaljujoč omenjeni cikcakasti razporeditvi vsakokrat po dva sosednja curka zadeneta drug v drugega. Kot posledica takšnega zaletavanja vodnih curkov in razpršitve nastaja vodna megla, ki je sicer spet na voljo v lepo izoblikovanem izstopnem curku, ki je poudarjen tudi v radialni smeri, po drugi strani pa je rešitev povezana z vrsto pomanjkljivosti. Kot prvo velja omeniti, da so kljub visokim tlakom kapljice vode v megli razmeroma velike. Dimenzije omenjenih kanalov oz. izpustov so nedvomno izjemno majhne. Sicer takšnih kanalov ni problem izdelati, problem pa je vzdrževati njihovo funkcionalnost med uporabo šobe. Gre pač spet za vodo, ki lahko vsebuje vodni kamen, delce nečistoč, ledu in podobno. Po drugi strani je pretakanje po kanalih povezano z ekstremnimi upori, zato mora biti tudi tlak dotekajoče vode izjemno visok. Slednje za sabo potegne vrsto sekundarnih učinkov, vključno z dražjimi napravami, ki so za to potrebne, večjim tveganjem okvar in višjo raven zahtevane varnosti pri rokovanju s tovrstnimi napravi, nenazednje pa tudi bistveno večjo energijo, ki je potrebna za doseganje tolikšnih tlakov.Also known from PCT / SE95 / 00007 (WO 95/18651) is a water mist spray nozzle consisting of a housing or a water mist. connection for connection to the supply line, as well as from the head coaxially inserted into said housing. The housing is equipped with a tapered surface at the outlet part, on which the nozzle head is also fitted with the tapered surface. Zigzag channels or channels are available on the conical surface of the nozzle head. discharges into which water enters the interior of the enclosure at a pressure of about 200 bar. Two and two adjacent channels converge with each other, so that, thanks to the said zigzag arrangement, the two adjacent jets each hit each other. As a result of such jetting of water jets and dispersion, water mist is created, which is again available in a nicely shaped exit jet, which is also emphasized in the radial direction, but on the other hand, the solution is related to a number of disadvantages. Firstly, despite the high pressures, the water droplets in the fog are relatively large. The dimensions of the said channels respectively. releases are undoubtedly extremely small. Otherwise, it is not a problem to create such channels, but the problem is to maintain their functionality while using the nozzle. It is again water that may contain limescale, impurities, ice and the like. On the other hand, channel flow is associated with extreme resistances, and the flowing water must also be extremely high. The latter entails a number of secondary effects, including the more expensive devices required, the greater risk of failure and the higher level of safety required when handling such devices, and last but not least the significantly higher energy required to achieve such pressures.

Šoba, s kakršno se ukvarja pričujoči izum in ki je namenjena zlasti za tvorbo megle, še zlasti vodne megle, sestoji iz soosno drugega ob drugem razporejenih ohišja in glave, ki je na omenjeno ohišje pričvrščena s pomočjo vijaka. Pri tem omenjeno ohišje obsega priključni del, ki je namenjen za priključitev šobe na vsakorat razpoložljivo napeljavo za dovajanje vode ter v ta namen prednostno opremljen z navojem.The nozzle of the present invention, which is intended, in particular, for the formation of fog, in particular water mist, consists of a coaxially arranged housing and a head which is secured to said housing by means of a screw. In this case, said housing comprises a connecting part which is intended for connecting the nozzle to any available water supply line and is preferably provided with a thread.

Pri šobi po izumu je med soosno poravnanima ter drugim ob drugega pritisnjenima ohišjem in glavo vpet s slednjima prav tako soosen osnovni cepilni sklop, ki obsega vsaj en cepilni element, ki je prednostno vsaj približno krožen ter zasnovan kot tenka elastična rozeta oz. membrana.In the nozzle according to the invention, there is also a coaxial basic splitting assembly comprising at least one splitting element, preferably at least approximately circular and designed as a thin elastic rosette, or between a coaxially aligned housing and a pressed housing against the other. membrane.

Poleg osnovnega cepilnega sklopa lahko šoba po izumu obsega še dodatni cepilni sklop, katerega cepilni element je razporejen vsaj v bistvu v ravnini osnovnega cepilnega elementa, vendar izven območja glave šobe, tako da le-to npr. obdaja. Zlasti je prednostno, če omenjeni dodatni cepilni sklop obsega izven območja glave in ohišja šobe razporejen dodatni cepilni element, ki je vsaj v bistvu krožno zasnovan in razporejen vsaj v bistvu v ravnini osnovnega cepilnega elementa med ohišjem in glavo šobe nameščenega osnovnega cepilnega sklopa, namreč prečno glede na vzdolžno os šobe ter na odmiku od zunanje obodne površine glave oz. ohišja šobe. Omenjeni dodatni cepilni element je prednostno držan s pomočjo iz glave šobe radialno navzven štrlečih držalnih nastavkov, še zlasti, če so ti ekvidistančno razporejeni po obodu omenjene glave šobe.In addition to the basic splitting assembly, the nozzle of the invention may further comprise an additional splitting assembly, the splitting element of which is arranged at least substantially in the plane of the basic splitting member, but outside the area of the nozzle head, such that e.g. surrounds. It is particularly advantageous if said additional splitting assembly comprises an additional splitting element arranged outside the area of the nozzle head and housing, which is at least substantially circular and arranged at least substantially in the plane of the basic splitting element between the housing and the nozzle head of the mounted basic splitting assembly, namely transversely with respect to the longitudinal axis of the nozzle and at a distance from the outer circumferential surface of the head, or. nozzle housings. Said additional splitting element is preferably held with the help of the nozzle head radially outwardly projecting the retaining nozzles, especially if these are arranged equidistantly along the circumference of said nozzle head.

Cepilni element osnovnega cepilnega sklopa šobe po izumu je opremljen z nizom obodno ali celo v obodni smeri ekvidistančno razporejenih skoznjih lukenj in/ali nizom obodno ali celo v obodni smeri ekvidistančno razporejenih izsekov vsakokrat ustreznega obrisa. Pri eni od možnih izvedb je omenjeni cepilni element vpet med vsaj dvema držalnima elementoma, ki sta pri tem skupaj s cepilnim elementom nataknjena na steblu omenjenega vijaka.The cleavage element of the basic nozzle assembly of the nozzle according to the invention is provided with a series of circumferentially or even circumferentially spaced through holes and / or a string circumferentially or even circumferentially spaced portions of each corresponding contour. In one embodiment, said cleavage member is clamped between at least two holding members, which together with the cleavage member are mounted on the stem of said bolt.

Omenjeno ohišje šobe po izumu sicer sestoji iz priključnega dela in usmerjevalnega oz. vodilnega dela, pri čemer je priključni del opremljen z navojem, usmerjevalni del pa je opremljen z nizom v osni smeri šobe potekajočih in v obodni smeri šobe ekvidistančno razporejenih skoznjih lukenj. Pri tem je usmerjevalni del ohišja v območju med skoznjimi luknjami na proti glavi šobe obrnjeni strani opremljen z gnezdom za prejem stebla vijaka, na nasprotni strani pa z vsaj v bistvu paraboloidno zasnovano ter osrednje razporejeno usmerjevalno izbočitvijo. Še nadalje je omenjeni usmerjevalni del ohišja v območju omenjenih skoznjih lukenj na proti glavi šobe obrnjeni strani opremljen zunanjo konusno ploskvijo ter z vbočeno obodno potekajočo površino, ki skupaj tvorita v obodni smeri potekajoč oster naležni rob. V tem primeru je tudi glava šobe na proti ohišju obrnjeni strani opremljena z ostrim, v obodni smeri potekajočim naležnim robom. Še zlasti je prednostno, če je z osrednje razporejeno skoznjo luknjo za prejem stebla vijaka opremljena glava na proti ohišju obrnjeni strani opremljena z ostrim obodno potekajočim robom, ki ga tvorita vbočena čelna površina in konusno posneta obodna ploskev, kot tudi, če je v osrednje razporejeni skoznji luknji za prejem stebla vijaka predvidena tudi razširitev za prejem glave vijaka. Tako je pri najbolj prednostni izvedbi z osrednje razporejeno skoznjo luknjo za prejem stebla vijaka opremljena glava na proti ohišju obrnjeni strani opremljena z ostrim obodno potekajočim robom, ki ga tvori vbočena čelna površina, sestoječa iz neposredno ob omenjeni skoznji luknji nahajajoče se zaokrožitve in iz slednje izhajajočega konusnega območja, skupaj s konusno posneto zunanjo obodno ploskvijo.Said nozzle housing according to the invention otherwise consists of a connecting part and a directional or. of the guide part, the connection part being threaded and the guiding part provided with a string in the axial direction of the nozzle of extending and circumferentially spaced through holes in the nozzle. In this case, the guide portion of the housing is provided with a socket for receiving the stem of the bolt in the area between the holes through the holes on the nozzle face, and on the opposite side with at least essentially a paraboloid-shaped and centrally arranged guiding projection. In addition, said guide portion of the housing in the area of said through holes on the nozzle facing side is provided with an outer conical surface and a concave circumferential running surface, which together form a sharp sharp edge in the circumferential direction. In this case, the nozzle head is also provided with a sharp, contiguous running edge in the circumferential direction, facing the housing. In particular, it is advantageous if the centrally arranged through hole for receiving the bolt head is provided with a head on the housing facing side having a sharp circumferentially extending edge formed by a concave front surface and a tapered circumferential surface, as well as when centrally arranged an extension for receiving the screw head is also provided through the hole for receiving the bolt stem. Thus, in the most preferred embodiment, with the central through hole for receiving the stem of the screw, the head on the housing facing side is provided with a sharp circumferential edge formed by a concave front surface consisting of rounding immediately adjacent to said through hole, and emerging from the latter. of the conical region, together with the conical tapered outer circumferential surface.

Tako je pri šobi po izumu med omenjenim naležnim robom, ki je na voljo na ohišju, in med naležnim robom, ki je na voljo na glavi šobe, s pomočjo skozi glavo šobe potekajočega ter v ohišje privitega vijaka vpet cepilni sklop, ki sestoji iz vsaj dveh na vsakokrat pripadajočih robovih nalegajočih držalnih elementov, med katerima je nameščen vsaj en izrazito tanek oz. kot membrana oz. kot rezilo zasnovan cepilni element. Pri eni od možnih izvedb je cepilni element cepilnega sklopa zasnovan iz notranjega kolobarja in zunanjega kolobarja, ki sta med seboj povezana preko niza vsaj v bistvu radialno potekajočih in prednostno v obodni smeri ekvidistančno razporejenih krakov. Pri tem je prednostno tudi vsak od držalnih elementov zasnovan analogno kot cepilni element, namreč iz notranjega kolobarja in zunanjega kolobarja, ki sta med seboj povezana preko vsaj v bistvu radialno potekajočih krakov.Thus, in the nozzle of the invention, a splitting assembly consisting of at least between the said contact edge available on the housing and between the contact edge available on the nozzle head is provided by means of a cleavage assembly consisting of at least two on each of the respective edges of the adjacent holding elements, between which at least one distinctly thin, or substantially thin, member is mounted. as a membrane or. as a blade designed cleavage element. In one embodiment, the splitting element of the splitting assembly is formed of an inner ring and an outer ring, which are interconnected via a series of substantially radially extending and preferably circumferentially spaced arms in the circumferential direction. Preferably, each of the holding members is also designed analogously as a splitting element, namely from an inner ring and an outer ring, which are connected to each other via at least substantially radially extending arms.

Za ustvarjanje vodne megle za gašenje požarov večjih razsežnosti je še zlasti primerna izvedba šobe, pri kateri je med soosno poravnanima ter drugim ob drugega pritisnjenima ohišjem in glavo šobe vpet z ohišjem in glavo prav tako soosen cepilni sklop, ki obsega vsaj en cepilni element, pri čemer je v usmerjevalnem delu ohišja na voljo niz vzdolžno potekajočih skoznjih lukenj, med katerimi je na voljo navojno gnezdo za prejem stebla vijaka, na čelni površini ohišja je predviden obodno potekajoč oster naležni rob, proti glavi šobe obrnjena površina pa je v območju lukenj vbočena in skupaj z zunanjo konusno površino tvori omenjeni rob. S skoznjo luknjo za prejem vijaka, ki je prednostno opremljena tudi z razširitvijo za prejem glave vijaka, opremljena glava je na svoji proti ohišju obrnjeni strani opremljena z ostrim obodno potekajočim naležnim robom, ki gaIn order to create a water fog for larger extensions, it is particularly suitable to design a nozzle in which a splitting assembly comprising at least one cleavage element is mounted between the coaxially aligned housing and the nozzle pressed together with the housing and the head. whereby a series of longitudinally extending through holes are provided in the guiding portion of the housing, between which a threaded socket is provided to receive the bolt stem; a circumferentially sharp abutting edge is provided at the front surface of the housing, and the surface facing the nozzle is convex and together with the outer conical surface, it forms said edge.

Nadalje je na glavo 2 šobe soosno z njo namestljiv tkzv. osnovni cepilni sklop 23, ki sestoji iz cepilnega elementa 230 ter iz držalnih elementov 231, 232. Cepilni element 230, ki je razporejen med držalnima elementoma 231, 232, je zasnovan kot lamela oz. kot membrana oz. kot nekakšen tanek kolut v obliki rezila iz tanke kovinske pločevine ali folije debeline npr. nekaj desetink mm. Omenjeni cepilni element 230 v splošnem obsega vsaj en cepilni rob 2300, ki se v vgrajenem stanju šobe nahaja v območju med vsakokrat pripadajočo luknjo 121 vodilnega dela 12 ohišja 1 in čelno površino 22 glave 2 šobe, hkrati pa med obema roboma 1250 ohišja 1 in 220 glave 2 oz. v njuni neposredni bližini. V tem stanju razmeroma vitek oz. elastičen oz. kot nekakšna membrana izveden cepilni element 230 držan zahvaljujoč primemo togima držalnima elementoma 231, 231, ki sta - stiskajoč med sabo cepilni element 230 - vpeta med omenjenima roboma 1250 in 220.Furthermore, the nozzle 2 is coaxially coaxial with the nozzle. a basic splitting assembly 23 consisting of a splitting member 230 and a holding member 231, 232. The splitting member 230, which is disposed between the holding members 231, 232, is designed as a lamella or. as a membrane or. like a thin blade in the form of a blade made of thin metal sheet or foil with a thickness of e.g. a few tenths of a mm. Said cleavage element 230 generally comprises at least one cleavage edge 2300, which, in the built-in state of the nozzle, lies in the area between the respective hole 121 of the guide portion 12 of the housing 1 and the front surface 22 of the head 2 of the nozzle and simultaneously between the two edges 1250 of the housing 1 and 220. heads 2 oz. in their immediate vicinity. In this state, relatively slim or. elastic or. as a kind of diaphragm, the cleavage element 230 is held in place thanks to the rigid gripping elements 231, 231 which are clamped between the cleavage member 230 between said edges 1250 and 220.

V danem primeru je v vodilnem oz. usmerjevalnem delu 12 ohišja 1 na voljo šest lukenj 121, cepilni element 230 pa je zasnovan kot kolut oz. rozeta, ki sestoji iz notranjega kolobarja 2301, zunanjega kolobarja 2302 in šestih radialno potekajočih krakov 2303, s pomočjo katerih sta povezana omenjena kolobarja 2301, 2302. Notranji kolobar 2301 je predviden za prejem stebla 31 vijaka 3, tako daje med obratovanjem šobe cepilni element 230 vpet med držalnima elementoma 231, 232 in hkrati s pomočjo vijaka 3 držan v svojem nespremenljivem položaju soosno zIn the given case it is in the leading or. six holes 121 are available to the directing portion 12 of the housing 1, and the splitting element 230 is designed as a reel, respectively. a rosette consisting of an inner annulus 2301, an outer annulus 2302, and six radially extending arms 2303, by means of which said annulus 2301, 2302 are connected. The inner annulus 2301 is provided for receiving the stem 31 of screw 3 so that the nozzle member 230 is operable clamped between the holding elements 231, 232, and at the same time supported by a screw 3 in its fixed position co-

-1111 ohišjem 1 in samo glavo 2 šobe. Držalna elementa 231, 232 sta zasnovana povsem podobno, namreč z obročema in radialnimi kraki, ki na skici niti niso posebej označeni. S tem je v danem primeru v območju držalnih elementov 231, 232 ter cepilnega elementa 230 na voljo šest prehodov. Strokovnjaku bo razumljivo, da so prednostno predvidena tudi sredstva za preprečevanje rotacije cepilnega elementa 230 ter držalnih elementov 231, 232 okoli vijaka 3, ki pa na skici v zvezi s to izvedbo šobe niti niso posebej prikazana, so pa vidna npr. na sl. 8 do 13.-1111 housing 1 and only head 2 nozzles. The holding elements 231, 232 are designed in a similar manner, namely, with rings and radial arms, which are not specifically marked in the sketch. In this case, there are six passages in the region of the holding elements 231, 232 and the splitting element 230. It will be appreciated by the person skilled in the art that the means for preventing rotation of the splitting element 230 and the holding elements 231, 232 around the bolt 3 are also provided, which are not shown in the drawing in connection with this embodiment of the nozzle but are visible, for example. in FIG. 8 to 13.

Med obratovanjem šobe je glava 2 s pomočjo vijaka 3 pritrjena na ohišje 1 šobe, pri čemer je cepilni element 230 vpet med držalnima elementoma 231, 232 ter skupaj z njima po eni strani s pomočjo vijaka 3 stisnjen med ohišje 1 in glavo 2 oz. natančneje med robom 1250 ohišja 1 in robom 220 glave 2 šobe. Sama šoba je s svojim priključnim delom 11 ohišja 1 priključena na ustrezen dovod vode pod tlakom, ki znaša npr. nekaj deset barov. Med cepilnim elementom 230 in sosednjima držalnima elementoma 231, 232 je na voljo sicer minimalna, pa vendarle za delovanje šobe pomembna zračnost, ki jo je mogoče uravnavati s pomočjo pritezanja vijaka 3. Voda, ki pod tlakom doteka skozi priključni del 11 ohišja 1, naleti na vodilni oz. preusmerjevalni del 12, in se enakomerno porazdeli po luknjah 121. Po prehodu skozi luknje 121 se voda porazdeli po takorekoč vsaj približno toroidnem območju, ki je v sestavljenem stanju šobe na voljo med ohišjem 1 in glavo 2 v območju držalnih elementov 231, 231 in cepilnega elementa 230. Zahvaljujoč po eni strani tlaku vode v omenjenem območju in po drugi strani špranji oz. zračnosti, ki je na voljo med cepilnim elementom 230 ter držalnima elementoma 231, 232 se tok vode cepi oz. razbije na ekstremno majhne vodne kapljice, ki tvorijo meglo. Velikost kapljic je premosorazmema z velikostjo reže oz. špranje ob cepilnem elementu 230 oz. zračnosti vpetja le-tega ter jo je v splošnem mogoče vnaprej določiti oz. prilagajati npr. namenu uporabe šobe.During operation of the nozzle, the head 2 is secured to the housing 1 of the nozzle by means of a screw 3, the splitting element 230 being clamped between the holding elements 231, 232 and, together with them, by a screw 3, pressed between the housing 1 and the head 2 or. more specifically, between the edge 1250 of the housing 1 and the edge 220 of the head 2 of the nozzle. The nozzle itself, with its connecting part 11 of the housing 1, is connected to a suitable supply of pressurized water, e.g. a few dozen bars. While a minimal but significant clearance is available for the operation of the nozzle 230 and the adjacent holding elements 231, 232, the playable nozzle can be controlled by tightening the screw 3. The water which flows under pressure through the connecting part 11 of the housing 1, encounters to the leading or diversion part 12, and is evenly distributed through holes 121. After passing through holes 121, water is distributed over at least approximately the toroidal area available in the composite state of the nozzle between the housing 1 and the head 2 in the region of the holding elements 231, 231 and the splitter element 230. Thanks to the water pressure in the said area, on the one hand, and the slits and / or gaps on the other. of the clearance available between the splitting element 230 and the holding elements 231, 232, the water flow is split or broken. it breaks into extremely small fog-forming water droplets. The size of the droplets is bridging with the size of the slit or. flush with the splitting element 230 oz. its air tightness and it can generally be determined in advance or. adjust e.g. the purpose of using the nozzle.

Zahvaljujoč še nadalje sami zasnovi oz. obliki omenjenega v bistvu toroidnega območja med ohišjem 1 in glavo 2 šobe v območju namestitve cepilnega elementa 230 in držalnih elementov 231, 232, namreč obliki površine 125 v območju lukenj 121 s pripadajočo konusno poševnino 1251 na vodilnem oz. usmerjevalnem delu 12 ohišja 1 in njej nasproti ležeče čelne površine 222 glave 2 šobe je opredeljena smer poteka curka megle, ki izteka iz šobe. V prikazanem primeru oz. pri zasnovi omenjenih površin 1251 ter 222, kakršna je bila predhodno opisana, ima curek obliko rotacijskega paraboloida z izrazito sploščenim temenom, kar je izjemno ugodno za potrebe gašenja požarov.Thanks to the design or design itself. in the form of the substantially toroidal area between the housing 1 and the nozzle head 2 in the area of mounting of the cleavage element 230 and the holding elements 231, 232, namely, the shape of the surface 125 in the area of holes 121 with the corresponding tapered oblique 1251 on the guide or. the directional part 12 of the housing 1 and the opposite direction of the front face 222 of the head 2 of the nozzle is determined by the direction of flow of the mist flowing out of the nozzle. In the example shown, respectively. in the design of said surfaces 1251 and 222, as previously described, the jet has the shape of a rotary paraboloid with a distinctly flattened top, which is extremely advantageous for fire fighting purposes.

Pri nadaljnji izvedbi šobe po izumu, ki je prikazana na sl. 4 - 7, je poleg osnovnega cepilnega sklopa 23 predviden še dodaten cepilni sklop 5, ki je namenjen še nadaljnjemu razbijanju in preusmerjanju vodnih kapljic iz osnovnega cepilnega sklopa 23 šobe po izumu izhajajoče megle.In a further embodiment of the nozzle of the invention shown in FIG. 4 - 7, in addition to the basic splitting assembly 23, an additional splitting assembly 5 is provided, which is intended to further break and divert water droplets from the basic splitting assembly 23 of the fog nozzle according to the invention.

Ta dodaten cepilni sklop 5 obsega vsaj en dodatni cepilni element 51, ki je spet nameščen prečno glede na vzdolžno os šobe, namreč v ravnini osnovnega cepilnega elementa 230.

V prikazanem primeru je dodatni cepilni element 51 zasnovan kot tenka rozeta, zasnovana kot kolobar, v svojem položaju pa je držan s pomočjo iz glave 2 šobe radialno navzven štrlečih držalnih nastavkov 52, ki so v prikazanem primeru ekvidistančno razporejeni po obodni površini glave 2 šobe. Zahvaljujoč omenjenemu dodatnemu cepilnemu sklopu 5 je pri šobi po izumu mogoče računati s curkom megle, katerega oblika ustreza obliki osno simetričnega ali asimetričnegaThis additional splitting assembly 5 comprises at least one additional splitting element 51, which is again positioned transversely with respect to the longitudinal axis of the nozzle, namely in the plane of the basic splitting element 230. At the same time, this additional splitting element 51 is outside the area of the head 2, namely at a distance from its outer circumferential surface and at the same time at a distance from the outer circumferential surface of the adjacent leading or. of the guide part 12 of the housing 1 of the nozzle. In the example shown, the additional splitting element 51 is designed as a thin rosette, designed as a ring, and in its position is held by the help of the nozzle head 2 extending radially outwardly from the retaining nozzles 52, which in this case are arranged equidistantly along the circumferential surface of the nozzle head 2. Thanks to the aforementioned additional splitting assembly 5, a mist can be calculated in the nozzle according to the invention, the shape of which corresponds to the axis symmetrical or asymmetric

Cepilni element po sl. 9 je prav tako osno simetrično zasnovan opremljen z nizom v obodni smeri ekvidistančno razporejenih izsekov 234 in razen tega tudi z nizom prav tako v obodni smeri ekvidistančno razporejenih skoznjih lukenj 233. Cepilni element po sl. 10 je asimetrično zasnovan in opremljen z nizom obodno razporejenih izsekov 234 različne velikosti. Cepilni element po sl. 11 je prav tako osno simetrično zasnovan opremljen z nizom v obodni smeri ekvidistančno razporejenih izsekov 234, ki se razlikujejo od tistih pri izvedbi po sl. 9, in razen tega tudi z nizom prav tako v obodni smeri ekvidistančno razporejenih skoznjih lukenj 233. Cepilni element 230 po sl. 12 je zasnovan kot osno simetričen kolut oz. rozeta, ki sestoji iz notranjega kolobarja 2301, zunanjega kolobarja 2302 in šestih radialno potekajočih, v bistvu puščičasto zasnovanih krakov 2303, s pomočjo katerih sta povezana omenjena kolobarja 2301, 2302. Cepilni element po sl. 13 je prav tako osno simetrično zasnovan opremljen z nizom v obodni smeri ekvidistančno razporejenih izsekov 234, ki se razlikujejo od tistih pri izvedbah po sl. 9 in 11, razen tega pa tudi z nizom prav tako v obodni smeri ekvidistančno razporejenih skoznjih lukenj 233.Further, in FIG. 8 to 13 show various embodiments of the splitting elements 230 of the basic splitting assembly 23, which contribute to the formation of either an axially symmetrical or asymmetric (Fig. 10) jet of mist. The graft element of FIG. 8 is axially symmetrically designed and provided with a series of circumferentially spaced sections 234. The splitting element of FIG. 9 is also axially symmetrically designed, provided with a series of circumferentially spaced portions 234 in the circumferential direction and, in addition, a string also of holes through the circumferentially spaced through equidistantly spaced holes 233. The splitting element of FIG. 10 is asymmetrically designed and provided with a series of circumferentially spaced sections 234 of various sizes. The graft element of FIG. 11 is also axially symmetrically designed, provided with a series of circumferentially spaced sections 234 in the circumferential direction, different from those of the embodiment of FIG. 9, and in addition, with a string also in the circumferential direction of equidistantly spaced through holes 233. The splitting element 230 of FIG. 12 is designed as an axially symmetrical disc. a rosette consisting of an inner ring 2301, an outer ring 2302 and six radially extending substantially arrow-shaped arms 2303, by means of which the said rings 2301, 2302 are connected. 13 is also axially symmetrically designed, provided with a series of circumferentially spaced sections 234 in the circumferential direction, which are different from those of the embodiments of FIG. 9 and 11, moreover, with a string also in the circumferential direction of equidistantly spaced through holes 233.

Predmetna šoba očitno odlikuje po razmeroma majhnem številu sestavnih delov, kar pomeni, daje enostavna za vzdrževanje, razen tega pa je tudi tveganje v zvezi s potencialnimi okvarami posameznih sestavnih delov temu primemo majhno.The nozzle is clearly distinguished by its relatively small number of components, which means that it is easy to maintain, and the risk of potential failure of individual components is low.

Ploščine prečnih prerezov lukenj 121 so razmeroma velike, zato so dopustni pretoki v primerjavi z doslej znanimi rešitvami šob za ustvarjanje megle lahko neprimerno večji. V primeru vdora delcev nečistoč lahko vsak delec onesposobi delovanje šobe zgolj na neznatnem odseku oboda cepilnega elementa 230, nikakor pa ne delovanja šobe v celoti. Mašenje šobe je torej kvečjemu postopno in ga je mogoče pravočasno zaznati in temu primemo ukrepati. Ker voda izteka skozi takorekoč obročasto špranjo, je možnost zamašitve šobe tudi zaradi vodnega kamna ali morebitnih drugih v vodi prisotnih nečistoč minimalna oz. če že do zamašitve pride, je ta zgolj lokalnega značaja in ne more ogroziti delovanja šobe kot take. Iz tega izhaja tudi izjemna zanesljivost delovanja šobe, kar je seveda ključnega pomena pri njeni uporabi za potrebe gašenja požarov. Zato je mogoče šobo po izumu uporabljati pri gašenju požarov celo največjih večjih razsežnosti, npr. skupino ali niz tovrstnih šob celo za gašenje požarov v predorih, rudnikih, letalih ter drugih prometnih in transportnih sredstvih kot tudi na naftnih vrtalnih ploščadih in v podobnih najhujših požarnih situacijah. Po drugi strani so tudi hidravlične izgube pri tovrstnih šobah razmeroma majhne.The cross-sectional areas of the holes 121 are relatively large, so the permissible flow rates may be significantly larger compared to the known fog nozzle solutions known to date. In the event of impurity particles being impregnated, each particle can only disable the nozzle operation on only a small section of the circumference of the splitting element 230, and in no way the nozzle operation completely. The nozzle movement is therefore progressive at most and can be detected in a timely manner and action must be taken. Since water flows through the annular slot, the possibility of clogging the nozzle is also minimal due to limescale or any other impurities present in the water. if clogging occurs, it is of a local nature and cannot jeopardize the operation of the nozzle as such. This also results in the extremely reliable operation of the nozzle, which is of course crucial in its use for fire fighting purposes. Therefore, the nozzle of the invention can be used to extinguish fires of even the largest extents, e.g. a group or series of such nozzles, even for extinguishing fires in tunnels, mines, aircraft and other means of transport and transport, as well as on oil drilling platforms and in similar severe fire situations. On the other hand, the hydraulic losses of such nozzles are also relatively small.
