Description
145775145775
Den foreliggende opfindelse angår en injektor, fortrinsvis til højtryksrensere, og af den i indledningen til krav 1 angivne art. En sådan injektor benyttes f.eks. netop i højtryksrensere til løbende indføring af flydende rensemiddel i det udsprøjtede vand, omend der normalt kun arbejdes med såkaldt "spuling", dvs. udsprøjtning med forholdsvis lavt tryk gennem en forholdsvis åben spuledyse. Ved egentlig højtryksudstråling gennem en snæver højtryksdyse vil det sjældent være relevant at tilsætte noget tilsatsmiddel til vandstrømmen, idet det i den situation alene gælder om at opnå et virkeligt højt tryk. Som pumpe benyttes en stempelpumpe, eller en anden fortrængningspumpe, hvorved den afgivne vandmængde vil eller kan være den samme i de to tilfælde, medens det benyttede tryk vil afhænge af størrelsen af den benyttede udsprøjtningsdyse. Ofte forekommer både den store og den snævre dyse på det sprøjteredskab, der er monteret ved den ydre ende af en fra renseren udgående højtryksslange, og dyserne kan benyttes valgfrit ved betjening af tilhørende operationsventiler på selve sprøjteredskabet.The present invention relates to an injector, preferably for high pressure cleaners, and of the kind specified in the preamble of claim 1. Such an injector is used e.g. precisely in high-pressure cleaners for continuous introduction of liquid detergent into the sprayed water, although usually only so-called "flushing", ie. spraying at a relatively low pressure through a relatively open flush nozzle. In the case of actual high-pressure radiation through a narrow high-pressure nozzle, it will rarely be relevant to add any additive to the water flow, since in that situation it is only necessary to achieve a really high pressure. As a pump, a piston pump or other displacement pump is used, whereby the amount of water delivered will or may be the same in the two cases, while the pressure used will depend on the size of the spray nozzle used. Often, both the large and the narrow nozzle appear on the spraying device mounted at the outer end of a high-pressure hose exiting the cleaner, and the nozzles can be used optionally when operating associated operating valves on the spraying device itself.
En effektiv injektor kræver en markant dyseindsnævring i hovedstrømbanen, og en sådan indsnævring er både nødvendig og acceptabel, når der arbejdes med lavtryksspuling med injektionstilsætning af tilsatsmidlet, medens den er uønsket, når der skal udføres højtrykssprøjtning, da den jo betinger et tryktab i udgangen til højtryksslangen.An efficient injector requires a significant nozzle constriction in the main flow path, and such a constriction is both necessary and acceptable when working with low-pressure flushing with injection additive of the additive, while undesirable when performing high-pressure spraying, since it does result in a loss of pressure at the output of high pressure hose.
Nu kunne man arbejde med en simpel, manuelt betjent omløbsventil, der ved højtryksdrift kunne åbnes til muliggørelse af fri udstrømning af væsken udenom injektoren og dennes indsnævring, men i praksis vil dette være en uheldig løsning, fordi brugeren helst skal kunne veksle frit mellem højtryksudstråling og spuling blot ved at betjene de tilhørende ventiler på sprøjteredskabet. Der er derfor allerede udviklet automatisk virkende omkoblingsindretninger, som reagerer på de forskellige tryk- og strømningsforhold ved åbning af hen- 2 145775 holdsvis en lille og en stor udstrømningsdyse, så vandet løber gennem injektoren ved lavt tryk og gen nem en omledningsforbindelse udenom injektordysen, når der arbejdes med højtryk.Now you could work with a simple, manually operated bypass valve which, in high pressure operation, could be opened to allow free flow of the fluid outside the injector and its constriction, but in practice this would be an unfortunate solution because the user should preferably be able to switch freely between high pressure radiation and flushing simply by operating the associated valves on the spray tool. Therefore, automatically acting switching devices have already been developed which respond to the various pressure and flow conditions by opening a small and a large outflow nozzle, respectively, so that the water flows through the injector at low pressure and through a bypass connection outside the injector nozzle when working with high pressure.
De hidtil kendte omkoblingsindretninger til dette brug er imidlertid ret komplicerede, og nærværende opfindelse har til formål at angive en injektor af den nævnte art, som kan udformes på særdeles enkel måde.However, the prior art switching devices for this use are quite complicated, and the present invention aims to provide an injector of the kind mentioned which can be designed in a very simple manner.
Dette formål opnås ved en injektor ifølge opfindelsen, som er ejendommelig ved de træk, der er angivet i den kendetegnende del af krav 1.This object is achieved by an injector according to the invention, which is characterized by the features defined in the characterizing part of claim 1.
Opfindelsen bygger på den erkendelse, at det er muligt helt at undgå det nævnte særlige omløb, når injektordysen er således indrettet, at den kan omstilles mellem at opvise dyseindsnævringen og at opvise et bredt gennemstrømningstværsnit, hvilket' er opnåeligt på enkel måde ved brug af en dysekerne, der sammen med en omgivende cylinderdel af gennemstrømningskammeret danner en snæver ringdyse eller f.eks. et antal rillebegrænsede dysepassager, medens der vil være fri gennemstrømmelighed i nævnte cylinderdel, når kernen fjernes derfra, hvilket udmærket kan ske på enkel automatisk styret måde.The invention is based on the recognition that it is possible to completely avoid said particular circulation when the injector nozzle is arranged so that it can be switched between exhibiting the nozzle constriction and exhibiting a wide flow cross-section, which is easily achieved by the use of a the nozzles which together with a surrounding cylinder part of the flow chamber form a narrow ring nozzle or e.g. a plurality of groove-limited nozzle passages, while there will be free flow-through in said cylinder portion when the core is removed therefrom, which may very well be done in a simple, automatically controlled manner.
Opfindelsen forklares i det følgende nærmere i forbindelse med tegningen, på hvilken:The invention will now be explained in more detail in connection with the drawing, in which:
Fig. 1 er et længdesnit gennem en injektor ifølge opfindelsen, medens fig. 2 er et tilsvarende billede af en ændret udførelse.FIG. 1 is a longitudinal section through an injector according to the invention, while FIG. 2 is a similar view of a modified embodiment.
Fig. 1 viser en injektorblok 2 med et gennemstrømningskammer 4, udformet med en tilgangsåbning 6 for trykvand fra en højtrykspumpe og en udstrømningsåbning 8 for tilslutning til en 145775 3 højtryksslange, der ved sin udløbsende er forsynet med et håndstykke med betjeningsventiler til åbning og lukning for henholdsvis en snæver højtryksdyse og en mindre snæver spuledyse. Endvidere har blokken 2 en sideåbning 10 for tilslutning til en beholder for flydende rensemiddel, der skal injiceres i hovedvandstrømmen.FIG. 1 shows an injector block 2 with a flow chamber 4 formed with an inlet port 6 for pressurized water from a high pressure pump and an outlet port 8 for connection to a high pressure hose provided at its outlet end with a handpiece with control valves for opening and closing respectively. narrow high pressure nozzle and a smaller narrow flush nozzle. Further, block 2 has a side opening 10 for connection to a liquid cleaner container to be injected into the main stream.
Bagtil, set i forhold til hovedstrømretningen, er kammeret 4 lukket ved hjælp af en skrueprop 12, der har en central passage til glidende gennemføring af en stang 14, der udvendigt har en stopmøtrik 16 og ved sin forende inde i kammeret 4 har en hoveddel i form af en dysekerne 18. I den viste aktive stilling er denne kerne beliggende inde i en omgivende bøsning 20, der er fast forbundet med blokken 2 og sammen med kernen 18 'begrænser en snæver dysepassage ved kernens yderside. Sideindløbet 10 er forbundet med et injektorrum 22 ved forenden af bøsningen 20.In the rear, in relation to the main flow direction, the chamber 4 is closed by means of a screw plug 12, which has a central passage for sliding through a rod 14, which externally has a stop nut 16 and at its front end within the chamber 4 has a main part in the in the active position shown, this core is located within a surrounding bush 20 which is firmly connected to the block 2 and, together with the core 18 ', limits a narrow nozzle passage at the outside of the core. The side inlet 10 is connected to an injector compartment 22 at the front end of the sleeve 20.
Den således beskrevne indretning vil virke som en injektor, når dysekernen indtager sin aktive stilling, men ved fuld tilbagetrækning af dysekernen 18 fra bøsningen 20 bliver der frit gennemløb gennem passagen 24 i bøsningen. Der kan herved dannes en snæver og effektiv dyseåbning, som vil opvise den brugsmæssige fordel, at den vil være lidet sårbar for total tilstopning, og som ydermere vil være meget let at rense, hvis den tilstoppes helt eller delvis.The device thus described will act as an injector as the nozzle core assumes its active position, but upon full withdrawal of the nozzle core 18 from the sleeve 20, free passage through the passage 24 into the sleeve. Hereby a narrow and effective nozzle opening can be formed which will show the useful advantage that it will be little vulnerable to total clogging and which will furthermore be very easy to clean if it is clogged completely or partially.
Det effektive dysetværsnit kan endvidere være let regulerbart derved, at dysekernen enten som helhed er svagt ind-snævrende i fremadgående retning eller ved at den har langsgående overfladeriller 27, der bliver brede og/eller dybere fremefter; den ønskede dysestørrelse kan herved fastlægges ved indstilling på stopmøtrikken 16, der jo bestemmer, hvor langt kernen rager ind i bøsningen 20 i den aktive stilling.Furthermore, the effective nozzle cross-section can be easily controllable in that the nozzle core is either as a whole narrowly narrower in the forward direction or in that it has longitudinal surface grooves 27 which become wider and / or deeper forward; the desired nozzle size can hereby be determined by adjusting the stop nut 16, which determines how far the core projects into the bush 20 in the active position.
Forskydningsbevægelsen af dysekernen i afhængighed af driftforholdene kunne for så vidt godt styres udefra ved hjælp af 4 145775 et udvendigt trykregistreringsudstyr i betjeningsforbindelse med den udragende ende af kernestangen 14, men dette vil være overflødigt, fordi dysekernen i sig selv kan udvirke de ønskede ændringer blot ved passende indretning og dimensionering.The displacement movement of the nozzle core, depending on the operating conditions, could well be controlled from the outside by means of an external pressure sensing device in operation with the protruding end of the core rod 14, but this will be superfluous because the nozzle core itself can effect the desired changes only by appropriate decor and sizing.
Bagenden af selve kernelegemet 18 virker som anslag for en trykfjeder 26, der med forspænding holder en skive 28 i anlæg mod en fast stopring 30 på kernestangen 14. Den indre ende af skrueproppen 12 udgør et anslag for skiven 28, men inderst findes en reces 32, som kan optage låseringen 30, således at kernestangen 14 kan skydes et stykke videre udad imod virkningen af fjederen 26. Når skiven 28 under bagudgå-ende bevægelse af dysekernen støder an mod skrueproppen 12, vil forenden af selve dysekernen 18 være beliggende i den med A betegnede stilling, nær bagenden af bøsningen 20, og ved videre udtrykning vil samme forende være i den med B betegnede yderstilling, når låseringen 30 støder an mod bunden af recessen 32 med fjederen 26 ekstra spændt.The rear end of the core body 18 acts as a stop for a compression spring 26 which biasly holds a washer 28 against a fixed stop ring 30 on the core rod 14. The inner end of the screw plug 12 constitutes a stop for the washer 28, but a recess 32 is provided at the bottom. which can receive the locking ring 30 so that the core rod 14 can be pushed further outwardly against the action of the spring 26. When the disc 28, during backward movement of the nozzle core, abuts the screw plug 12, the front end of the nozzle core 18 will be located in the A designated position, near the rear of bush 20, and by further expression, the same front end will be in the outer position designated by B when the locking ring 30 abuts the bottom of recess 32 with spring 26 extra tight.
Når højtrykspumpen startes, vil der ske en generel trykopbygning i hele systemet, også selvom der arbejdes med særlige midler til at mindske dette tryk, så længe der er lukket for udløbsdyserne. Alt efter størrelsen af dette tryk vil dysekernesystemet være forskudt til mere eller mindre hårdt anlæg mod proppen 12, dvs. kerneforenden vil stå i stilling B eller eventuelt imellem A og B.When the high-pressure pump is started, a general pressure build-up will occur throughout the system, even if special means are used to reduce this pressure as long as the outlet nozzles are closed. Depending on the magnitude of this pressure, the nozzle core system will be displaced to more or less hard abutment against the plug 12, ie. the core front end will be in position B or optionally between A and B.
Når der åbnes for den forholdsvis store spuledyse ved udløbet, vil pumpen, der er en fortrængningspumpe, arbejde med fuld kapacitet, idet de nævnte trykreducerende midler gøres inaktive ved den begyndende udstrømning fra pumpen, men netop da spuledysen er stor og vandmængden begrænset, vil der ikke opbygges noget særligt stort tryk i kammeret 4. Der kan eksempelvis være tale om et tryk på ca. 25 bar. Fjederen 26 er imidlertid indrettet til at kunne overvinde dette tryk og altså til at holde eller bringe dysekernen 18 i eller til 145775 5 stilling A. I denne stilling er kernens forende beliggende tilstrækkelig nær ved den bageste del 34 af bøsningen 20 til, at der omkring den forekommer en fremadrettet vandstrøm, der ved at skabe undertryk på kernens forreste endeflade trækker kernesystemet mod højre indtil den aktive stilling nås ved anslaget af stopmøtrikken 16 mod ydersiden af proppen 12. Hermed er injektordysen dannet, og en tilhørende trykstigning i kammeret 4 formår ikke længere at føre kernesystemet fremad.When the relatively large flushing nozzle is opened at the outlet, the pump, which is a displacement pump, will operate at full capacity, making said pressure reducing agents inactive at the initial outflow from the pump, but just because the flushing nozzle is large and the water flow is limited. no particularly large pressure builds up in the chamber 4. For example, there may be a pressure of approx. 25 bar. However, the spring 26 is adapted to be able to overcome this pressure and thus to hold or bring the nozzle core 18 into or to position A. In this position, the front of the core is located close enough to the rear portion 34 of the bushing 20 to allow about it provides a forward flow of water which, by creating negative pressure on the front end face of the core, pulls the core system to the right until the active position is reached by the stop of the stop nut 16 towards the outside of the plug 12. This results in the injector nozzle and a corresponding pressure rise in the chamber 4 to advance the core system.
Når der lukkes for spuledysen, vil strømningen langs kernen ophøre, og der vil straks opbygges et sådant generelt overtryk i systemet 4,8, at kernesystemet vil blive trykket mod den passive stilling svarende til den beskrevne begyndelsesstilling, hvori kernen fortrinsvis står i stilling B.When the coil nozzle is closed, the flow along the core will cease and immediately such a general overpressure will build up in the system 4.8 that the core system will be pressed against the passive position corresponding to the initial position described, wherein the core is preferably in position B.
Hvis der derefter åbnes for den snævre højtryksdyse, sker der ikke noget betydende trykfald i kammeret 6, og da pumpen også nu arbejder med fuld kapacitet, nemlig nu med stan-dard-volumenstrøm under meget højt tryk, vil kernen blot blive trykket endnu kraftigere bagud mod stilling B, henholdsvis straks blive udpresset til denne stilling, og højtryksudsprøjtningen kan således foregå uden at injektordysen overhovedet etableres, dvs. uden noget deraf fremkaldt mellemtryktab. Når højtryksdysen lukkes, befinder kernesystemet sig i udgangsstillingen og er som beskrevet klar til at reagere, hvis den store spuledyse åbnes.If the narrow high-pressure nozzle is then opened, no significant pressure drop occurs in chamber 6, and as the pump is also now operating at full capacity, namely now with standard volume flow under very high pressure, the core will simply be pushed even more forcefully backwards towards position B, respectively, immediately being squeezed to this position, and the high-pressure spraying can thus take place without the injector nozzle being established at all, ie. without any consequent loss of medium pressure. When the high-pressure nozzle is closed, the core system is in its initial position and, as described, is ready to respond if the large flush nozzle is opened.
Hvis der efter en spuleoperation, hvori dysekernen er aktiv, lukkes for spuledysen, vil dysekernen 18 alligevel straks vandre til den helt passive stilling B, fordi der jo straks vil opbygges et så kraftigt tryk i afgangen 8, at dette vil påvirke kernesystemet med en bagudgående kraft, der er betydeligt større end den fremadgående kraft, som selve vandstrømningen giver anledning til.However, if after a flush operation in which the nozzle core is active, the flush nozzle is closed, the nozzle core 18 will immediately migrate to the fully passive position B, because after all, such a strong pressure will be built up in the outlet 8 that this will affect the core system with a backward force that is significantly greater than the forward force that the water flow itself gives rise to.
Det skal slutteligt nævnes, at det for en given højtryksrenser med given ydelse er muligt at indføre en betydeligt stør- 6 145776 re mængde tilsætningsmiddel gennem injektoren ifølge opfindelsen end gennem de hidtil kendte injektorer; forsøg synes at vise, at der kan indføres helt op til den dobbelte mængde, og forholdet formodes at bero på, at væsken i injektionsområdet opviser et meget større overfladeareal end ved brug af en dyse med en cirkulær åbning. Det viser sig, at indtaget af tilsætningsmiddel er uafhængig af vandmængdestrømmen; nogle højtryksrensere er forsynet med et kortsluttende pumpeomløb, der kan åbnes delvis for opnåelse af en kapacitetsregulering, eventuelt styret i afhængighed af arbejde trykket, og netop da tilsætningen er stort set afhængig af vandstrømmens størrelse, kan man altså udvirke en regulering af tilsætningsprocenten ved direkte eller indirekte at regulere på kapaciteten. Desuden kan en regulering naturligvis også udføres ved betjening af stopmøtrikken 16 til ændring af den aktive beliggenhed af det let koniske kernelegeme 22.Finally, it should be mentioned that for a given high-pressure cleaner with a given performance, it is possible to introduce a significantly greater amount of additive through the injector according to the invention than through the prior art injectors; tests seem to show that up to twice the amount can be introduced, and the ratio is supposed to be due to the fact that the liquid in the injection area has a much larger surface area than when using a nozzle with a circular aperture. It turns out that the intake of additive is independent of the water flow; some high-pressure cleaners are provided with a short-circuit pump circulation, which can be opened partially to achieve a capacity regulation, possibly controlled depending on the work pressure, and precisely because the addition is largely dependent on the size of the water flow, a regulation of the addition percentage can be effected by direct or indirectly regulating on capacity. In addition, of course, regulation can also be made by operating the stop nut 16 to change the active location of the slightly tapered core body 22.
Det kan eventuelt være kernen 18, som er fast, medens bøsningen 20 er bevægelig for rensning, indstilling eller neutralisering af dysen.It may optionally be the core 18 which is fixed while the bushing 20 is movable for cleaning, adjusting or neutralizing the nozzle.
Dyseåbningen behøver ikke at være en cirkulær spalte eller at være dannet af regelmæssigt fordelte, langsgående riller i en eller begge af de i dyseområdet modstående flader; selve dyseåbningen eller -åbningerne kan forefindes langs kun en del, f.eks. kun den ene halvdel af dysekernens omkreds.The nozzle opening need not be a circular slit or be formed of regularly spaced longitudinal grooves in one or both of the faces opposed to the nozzle region; the nozzle orifice itself may be present along only a portion, e.g. only one half of the nozzle core circumference.
Denifig. 2 viste udførelse adskiller sig ikke principielt fra fig. 1, og modsvarende henvisningsbetegnelser er benyttet. Bøsningen 20 er udformet med en bagudragende cylindrisk del 21 med en inderdiameter, som er kun lidt større end diameteren af den med 23 betegnede anslagsdel for fjederen 26, hvorved kernens fremskydningsbevægelse til den punkteret viste, aktive stilling på fordelagtig måde kan foregå over en større længde end i fig. 1. Indvendigt i bøsningen 20 findes en udvidelse 25 på det sted, hvor delen 23 er beliggende i den 7 1A5775 aktive stilling, således at der ikke opstår noget unødigt trykfald. Fortrinsvis er kernen 18 udformet med fladfræsede facetter 27, der definerer dyseåbningerne, medens de tilbageværende dele af den oprindelige cylinderoverflade virker som styr mod den ydre dyseflade. Facetterne er ikke generelt indadskrånende fremefter, men kun i området 29 ved deres bageste ender, og med dette område samvirkende med dysefladen 24 i den aktive stilling, vil dysen være let at justere ved indstilling af det foran omtalte anslagsstop 16 for fremskydningen.Denifig. 2 does not differ in principle from FIG. 1 and corresponding reference numerals are used. The sleeve 20 is formed with a rearwardly extending cylindrical portion 21 having an inner diameter which is only slightly larger than the diameter of the abutment portion indicated by 23 for the spring 26, whereby the core movement of the core to the punctured active position may advantageously take place over a greater length. than in FIG. 1. Inside the sleeve 20 is an extension 25 located at the location where the portion 23 is located in the active position so that no unnecessary pressure drop occurs. Preferably, the core 18 is formed with flat milled facets 27 defining the nozzle openings, while the remaining portions of the original cylinder surface act as guide against the outer nozzle surface. The facets are not generally inwardly inclined but only in the region 29 at their rear ends, and with this region cooperating with the nozzle surface 24 in the active position, the nozzle will be readily adjustable by adjusting the aforementioned impact stop 16 for the advance.
