Opfindelsen angår en taphane til at forbinde to ledninger med en afgangsåbning på en væskebeholder, især ølbeholder, hvis afgangsåbning har to koncentriske passager, der kan afspærres ved hjælp af ventiler, såsom en kontraventil for gassen, 5 der kan åbnes af gastryk ind mod væskebeholderen, og en væske ventil, der kan åbnes for væskeudstrømning fra beholderen efter mekanisk påvirkning fra en påsat taphane, og hvor hanen har et hus, som kan forbindes tætnende med beholderen, og i hvilket der er indsat en forskydelig, rørformet ventilskyder, 10 og der mellem denne og huset er udformet en med en ydre tryk- middelledning forbindbar gaskanal, som ved hjælp af en mellem ventilskyderen og huset anbragt pakning kan afspærres fra og forbindes gastæt med beholderen, hvorhos ventilskyderen har en ud af huset ragende hul del, som sammen med ventil-15 skyderens indre danner en væskekanal, som kan forbindes med en væskeledning.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a tap valve for connecting two lines to a discharge port on a liquid container, in particular a beer container, the discharge port having two concentric passages which can be blocked by valves, such as a gas check valve, which can be opened by gas pressure into the liquid container. and a liquid valve which can be opened for liquid outflow from the container after mechanical action from an attached tap cock, and wherein the male has a housing which can be sealingly connected to the container and into which a slidable tubular valve slider is inserted, and between this and the housing are formed a gas duct, which can be connected to an external pressure line, which can be blocked by means of a gasket arranged between the valve slider and the housing with the container, the valve slider having a hollow part projecting out of the housing, which together with valve The interior of the slider forms a fluid channel which can be connected to a liquid conduit.

Fra beskrivelsen til østrigsk patent nr. 273.706 kendes en taphane af denne art, som ved indsætning og indpresning i 20 en afgangsåbning på et fad åbner fadventilen, og hvis gaskanal samtidig åbnes. Til fiksering af taphanen på fadet må denne presses længere ind. Det er ved denne taphane ikke muligt at afspærre såvel gaskanalen som væskekanalen. Ved påsat taphane forbliver afgangsåbningen fra fadet således til stadighed 25 åben, så at der både for gasledningen og væskeledningen må anvendes et selvstændigt ekstra afspærringsorgan. Ved indpresning af taphanen kan der ske udstrømning af væske, så længe taphanen endnu ikke er presset tilstrækkeligt langt ind. Dette er især tilfældet, hvis taphanen ikke holdes nøjagtigt flugtende 30 med fadets afgangsåbning, og væsken i fadet står under tryk.From the specification of Austrian Patent No. 273,706, a tap valve of this kind is known which, when inserting and pressing into a outlet outlet on a dish, opens the dish valve and whose gas duct is simultaneously opened. To fix the tap tap to the dish, it must be pressed further in. At this tap, it is not possible to shut off both the gas duct and the liquid duct. Thus, with the tap tap applied, the outlet opening from the barrel remains open continuously so that an independent additional shut-off means must be used for both the gas line and the liquid line. When the tap tap is pressed out, liquid can be effected as long as the tap tap has not been pressed in far enough. This is especially the case if the tap tap is not kept exactly flush with the outlet opening of the dish and the liquid in the dish is pressurized.

Formålet med opfindelsen er at undgå disse ulemper og vanskeligheder og at tilvejebringe en taphane af den i indledningen omhandlede art, ved hjælp af hvilken væskebeholderens ventil først åbnes efter 35 påsætning og fiksering af taphanen på væskebeholderen, og ved hvilken ledningen, som kan forbindes med ventilen, lukkes ved hjælp af et enkelt afspærringsorgan. Uønsket udstrømning 2 148813 af gas og vaske, især ved påsættelse af taphanen, skal herved med sikkerhed kunne forhindres.The object of the invention is to avoid these drawbacks and difficulties and to provide a tap of the kind referred to in the preamble, by means of which the valve of the liquid container is only opened after the application and fixing of the tap valve to the liquid container and by which the cord which can be connected to the valve , is closed by a single locking means. Undesirable outflows of gas and sinks, especially when the tap tap is applied, must thereby be safely prevented.

Dette er ifølge opfindelsen opnået ved, at der i den bort 5 fra beholderen vendte del af ventilskyderen findes et i forhold til huset fikseret afsparringsstempel for væskekanalen, hvorhos ventilskyderen i taphanens hus ved hjælp af et manuelt betjen-bart, fortrinsvis over et gevind virkende indstillingsorgan kan bevæges frem og tilbage mellem en lukkestilling, hvori 10 - den spærrer begge kanalerne, og en åbnestilling, hvori den åbner for begge kanalerne, og hvor enden af ventilskyderen åbner væskeventilen i beholderen.This is achieved according to the invention in that in the portion of the valve slider turned away from the container there is a locking piston fixed to the housing, the valve slider of the tap valve housing being provided by a manually operable, preferably over a threaded adjusting means. can be moved back and forth between a closing position in which 10 - it locks both channels and an opening position in which it opens for both channels and where the end of the valve slider opens the liquid valve in the container.

Indstillingsorganet er fortrinsvis udformet som en på huset 15 drejeligt lejret og i et gevind i ventilskyderen indgribende møtrik, idet ventilskyderen er sikret mod drejning i forhold til huset. Herved er det muligt at finjustere indstillingen af taphanen.The adjusting means is preferably configured as a rotatable bearing on the housing 15 and in a thread engaging the valve slider, the valve slider being secured against rotation relative to the housing. This makes it possible to fine-tune the setting of the tap.

20 I en foretrukken udførelsesform er møtrikken udformet som en aksialt opdelt overløbermøtrik, som har en not, der griber ind over en flange på huset, og hvor møtrikkens dele sammenholdes af en som en enhed udformet bøsning, som er sikret mod drejning i forhold til møtrikken, hvorved samlingen af taphanen 25 kan ske på meget enkel måde.In a preferred embodiment, the nut is designed as an axially divided overflow nut having a groove engaging over a flange of the housing and the nut parts being held together by a sleeve-shaped sleeve secured against rotation relative to the nut. , whereby the assembly of the tap tap 25 can be effected in a very simple manner.

Overløbermøtrikkens dele har hensigtsmæssigt hver en flange, som griber ind i en not på det centralt i ventilskyderens indre anbragte stempel, hvorved stemplet uden andre dele holdes 30 i en i forhold til huset fastlagt stilling.Conveniently, the overflow nut portions each have a flange which engages a groove on the piston located centrally in the inner of the valve slider, thereby holding the piston without other parts in a position determined relative to the housing.

Det'er hensigtsmæssigt, at ventilskyderens udragende del er ført gennem en i siden af huset anbragt slids, idet taphanens byggehøjde derved kan holdes lille, og ventilskyderen samtidig 35 er sikret mod drejning i forhold til huset.Conveniently, the protruding portion of the valve slider is passed through a slot disposed in the side of the housing, thereby maintaining the tap height of the tap valve and at the same time the valve slider is secured against rotation relative to the housing.

Opfindelsen forklares i det følgende nærmere i forbindelse 148813 3 med et udførelseseksempel for taphanen og under henvisning til tegningen, hvor fig. 1 viser et aksialt snit gennem taphanen i lukket stilling 5 og fig. 2 taphanen i åben stilling.The invention will now be explained in more detail in connection with an exemplary embodiment of the tap and with reference to the drawing, in which fig. 1 shows an axial section through the tap in the closed position 5 and FIG. 2 the tap cock in the open position.

Med henvisningstallet 1 er betegnet et hus, hvis nederste 10 ende er forsynet med et bajonetlukke 2, hvormed det kan påsættes og fikseres i en ikke vist afgangsåbning i en væskebeholder, f.eks. et ølfad. Huset 1 bringes derved i tætnende forbindel-delse med afgangsåbningen ved hjælp af en ringformet pakning.By reference numeral 1 is indicated a housing whose bottom end is provided with a bayonet closure 2, with which it can be mounted and fixed in an outlet port not shown in a liquid container, e.g. a beer platter. The housing 1 is thereby sealingly connected to the outlet opening by means of an annular gasket.

I huset er i en i hovedsagen cylindrisk aksial udsparing 4 15 indsat en rørformet ventilskyder 5, som har en hul del 6, som rager ud gennem en i siden af huset udformet langdeslids 7. Den hule del 6 danner sammen med det indre af venti1skyderen en væskekanal 8 og har ved sin ene ende 9 et gevind for tilslutning af en ikke vist væskeledning. Ventilskyderen 5 er forskyde-20 lig i retning af den aksiale udsparing 4 i huset.In the housing is inserted in a generally cylindrical axial recess 4 15 a tubular valve slider 5, which has a hollow part 6 protruding through a longitudinal slit 7 formed in the side of the housing. The hollow part 6 forms together with the interior of the valve slider a fluid channel 8 and has at one end 9 a thread for connecting a fluid line not shown. The valve slider 5 is displaceable in the direction of the axial recess 4 in the housing.

Mellem huset og ventilskyderen dannes en ringformet gaskanal 10, hvori udmunder en fra en studs 11 udgående boring 12.Between the housing and the valve slider an annular gas duct 10 is formed, in which a bore 12 extending from a stud 11 opens.

Til studsen kan under indkobling af en læbeventil 13 tilsluttes 25 en ikke vist ledning for et gastrykmiddel. Som det ses af fig. 1, er den ringformede gaskanal 10 ved lukket taphane tættet ved hjælp af to ringformede pakninger 14,15, f.eks.A plug (not shown) for a gas pressure means can be connected to the plug during connection of a lip valve 13. As seen in FIG. 1, the annular gas duct 10 at the closed tap is sealed by two annular gaskets 14,15, e.g.

O-ringe foroven og forneden. Den nederste, nærmest fadet anbragte pakning 15 er som vist i fig. 1 anbragt tæt ved den nederste 30 ende af huset, således at den ved forskydning af ventilskyderen 5 i retning mod fadet træder ud af huset. Herved åbnes forbindelsen mellem gaskanalen 10 og fadet, og drivgas (CC>2 eller luft) kan gennem ledningen for gastrykmiddel via boringen 12 i gaskanalen ledes ind i det indre af fadet (fig. 2).O-rings top and bottom. The lower, closest to the dish, gasket 15 is shown in FIG. 1 is positioned close to the lower end of the housing so that, when displacing the valve slider 5 in the direction towards the dish, it exits the housing. This opens the connection between the gas duct 10 and the barrel, and propellant gas (CC> 2 or air) can be passed through the gas pressure line via the bore 12 in the gas duct into the interior of the barrel (Fig. 2).

Til forskydning af ventilskyderen 5 tjener en i et gevind 16 ved den øverste ende af ventilskyderen indgribende møtrik 35 4 148813 17, som er drejelig på en på huset 1 anbragt flange 18, hvorover den griber med en not 19. Møtrikken er aksialt opdelt i to dele 17',17" og kan således aftages i sideretningen. De to dele 17',17" holdes sammen med hjælp af en som et håndtag 5 ud i ét stykke formet bøsning 20, der skydes ind over de to samlede dele og er sikret mod drejning i forhold til disse dele ved hjælp af en not-feder-centrering 21. Håndtaget 20 og møtrikken 17 er fortrinsvis fremstillet af plastmateriale. Længden af ventilskyderen er dimensioneret således, at dens 10 nederste ende 5' i tilbagetrukket stilling, dvs. når væske kanalen er afspærret, kommer til at ligge over den endnu lukkede indre fadventil. Først når ventilskyderen forskydes i retning mod fadet, træder den med sin nederste ende i berøring med den indre fadventil og åbner denne.For displacement of the valve slider 5, a nut 35 engaging nut 35 4 148813 17 engaging a thread 16 which is pivotable on a flange 18 mounted on the housing 1, over which it engages a groove 19. The nut is axially divided into two portions 17 ', 17 "and thus can be detached in the lateral direction. The two parts 17', 17" are held together with the aid of one as a handle 5 in one-piece bush 20 which is inserted over the two assembled parts and is secured. against rotation with respect to these parts by a not-spring centering 21. The handle 20 and the nut 17 are preferably made of plastic material. The length of the valve slider is dimensioned such that its lower end 5 'in the retracted position, i.e. when the liquid duct is blocked, it will lie above the still closed inner faucet valve. Only when the valve slider is displaced in the direction of the dish does it contact its lower end with the inner dish valve and opens it.

Ved den øverste ende af møtrikken 17 findes en indadrettet flange 22, på hvilken et stempel 23 ved hjælp af en not 24 i dette er lejret således, at det rager ind i ventilskyderens 5 indre rum, centreret i dette. Herved er stemplet 23 fast-20 holdt i forhold til huset 1. Ventilskyderen 5 er dog aksialt bevægelig i forhold til stemplet 23.At the upper end of the nut 17 is an inwardly directed flange 22 on which a piston 23 is supported by a groove 24 in it so that it projects into the inner space of the valve slider 5, centered therein. Hereby the plunger 23 is held in relation to the housing 1. However, the valve slider 5 is axially movable relative to the plunger 23.

Stemplet 23 rækker, når taphanen er lukket, med sin i ventil-skyderen indragende ende, der bærer en pakning 25, ned til 25 en konisk tætningsflade 26 på ventilskyderens 5 væg omkring væskekanalen 8 efter indmundingen af den hule del 6 og afspærrer således med denne pakning 25 væskekanalen 8. Til tætning af stemplet udad i retning mod håndtaget findes endnu, en mod indervæggen i ventilskyderen rettet ringformet pakning 27.The piston 23, when the tap valve is closed, extends with its end projecting into the valve slider carrying a gasket 25, down to 25, a tapered sealing surface 26 on the wall of the valve slider 5 around the liquid channel 8 after the mouth of the hollow part 6, thus blocking with this packing 25 the liquid channel 8. To seal the piston outwards in the direction of the handle, there is still an annular gasket 27 directed towards the inner wall of the valve slider.

30 Håndtaget er fastgjort i aksial retning til stemplet 23 ved hjælp af en centreret skrue. 28.The handle is secured in axial direction to the piston 23 by means of a centered screw. 28th

Taphanen virker på følgende måde: 35 Før anbringelsen skal taphanen være lukket, hvorved væskekanalen 8 og gaskanalen 10 er afspærret, således at væske, der står i væskeledningen, ikke kan strømme ud, og drivgassen er hindretThe tap valve works as follows: 35 Before the application, the tap tap must be closed, whereby the liquid duct 8 and the gas duct 10 are blocked so that liquid contained in the liquid conduit cannot flow out and the propellant gas is obstructed.

Claims

5 When the handle 20 is turned, the valve slider 5 is moved downwardly in the two-piece nut 17 and thereby downwardly relative to the housing 1, the piston 23 being held stationary by the flange 22 on the nut 17. The sealing surface 26 formed on the valve slider 5 moves downwardly relative to the piston. 23, thereby opening the liquid channel 108. During the downward movement, the valve slider 5 presses, with its lower end projecting from the housing 5, to the inner valve in the outlet opening of the dish, thereby releasing the flow of liquid. In the downward movement of the valve slider 5, the O-ring 15 simultaneously exits the housing duct 15 and seals the propellant gas duct at the outlet of the dish. The propellant gas can thus flow into the dish. The O-ring 29 serves to provide extra security. At the low seal road of only approx. 2 mm, it is affected substantially less than the O-ring 14, so that it has a substantially longer life span than this one. Claims. 1 2 3 4 5 6 7 8 9 10 11
