Opfindelsen beskæftiger sig med reguleringsapparater/ der anvender en membran til - uanset tilgangstrykket og forbruget - at opretholde et i hovedsagen konstant afgangstryk/ specielt ved gasreduktionsventiler.The invention relates to control devices / which use a diaphragm to maintain - regardless of the supply pressure and consumption - a substantially constant discharge pressure / especially at gas reduction valves.
5 Fra beskrivelsen til US patent nr. 3 900 045 kender man en gasreduktionsventil, der omfatter en membran,hvis ene side er i kontakt med en plade, og hvis kant er fastklemt mellem et hus og et dæksel. Huset og dækslet har fortrinsvis form som omdrejningslegemer i forhold til en 10 akse. Membranen deler det af huset og dækslet afgrænsede rum op i to kamre. Det ene kammer indeholder pladen samt en fortrinsvis i afstand fra aksen beliggende fjeder, der presser på pladen. Det andet kammer har forbindelse med en afgangsstuds og med en tilgangsstuds, over hvis 15 munding membranen presses, når pladen vipper om et mellem fjederen og mundingen beliggende støttepunkt. Støttepunktet og fjederen befinder sig fortrinsvis på hver sin side af aksen. Fremstillingen af denne reduktionsventil foregår på følgende måde: Man anbringer den med pladen 20 forbundne membran på huset. Man placerer fjederen på pladen. Man placerer dækslet på huset rundt om fjederen.From the specification of US Patent No. 3,900,045, a gas reduction valve is known which comprises a diaphragm whose one side is in contact with a plate and the edge of which is clamped between a housing and a cover. The housing and cover preferably take the form of revolving bodies relative to an axis. The diaphragm divides the space of the house and cover boundary into two chambers. One chamber contains the plate as well as a preferably spaced spring which presses on the plate. The second chamber communicates with an outlet nozzle and with an inlet nozzle above which the orifice diaphragm is pressed as the plate tilts about a support point located between the spring and the orifice. The support point and the spring are preferably located on either side of the axis. The preparation of this reduction valve is carried out as follows: The membrane connected to the plate 20 is placed on the housing. You place the spring on the plate. Place the cover on the housing around the spring.
Medens man holder dækslet imod fjederens kraft, foretager man en foreløbig indfalsning, hvorefter den halvfærdige samling bringes til en anden arbejdsstation, 25 hvor falsningen færdiggøres.While holding the cover against the force of the spring, a preliminary folding is performed, after which the semi-finished assembly is brought to another workstation, where the folding is completed.
Opfindelsen giver anvisning på en gasreduktionsventil, der er enklere at fremstille end den kendte reduktionsventil .The invention provides a gas reduction valve which is easier to manufacture than the known reduction valve.
Med henblik herpå omfatter en gasreduktionsventil 30 af den indledningsvis nævnte art midler til tilbageholdelse af pladen på daskslet.To this end, a gas reduction valve 30 of the type mentioned initially comprises means for retaining the plate on the casing.
Fremgangsmåden ved fremstilling af en sådan gasreduktionsventil foregår ved, at der tilvejebringes en enhed, der består af en membranbæreplade, der tilbage-35 holdes i et dæksel efter anbringelse af en fjeder mellem pladen og dækslet. Denne enhed behøver ingen foreløbig 2The process of producing such a gas reduction valve is by providing a unit consisting of a membrane support plate which is retained in a cover after a spring is placed between the plate and the cover. This device does not need any preliminary 2

indfalsning og kan transporteres fra en arbejdsstation til en anden uden behov for trykpåvirkning på dækslet.fold-in and can be transported from one workstation to another without the need for pressure on the cover.
Takket være de nævnte midler til tilbageholdelse af pladen på dækslet vil de enkelte dele af enheden ikke kunne 5 løsne sig fra hinanden. Man afskaffer således operationen til foreløbig indfalsning og vanskelighederne med at opretholde trykpåvirkning på dækslet under operationerne.Thanks to the said means for holding the plate on the cover, the individual parts of the unit will not be able to detach from each other. The operation is therefore abolished for preliminary folding and the difficulties in maintaining pressure on the cover during the operations.
Man opnår desuden en helt tilfredsstillende ventilfunktion, idet den af pladten og membranen bestående enhed, 10 der tilbageholdes i den ene side,'er i stand til uden forhindring og uden risiko for blokering at vippe i forhold til støttepunktet, selv om ventilens enkelte be-! standdele ikke er fremstillet med meget præcise toleran cer.In addition, a completely satisfactory valve function is achieved, since the plate and diaphragm unit, which is retained on one side, is able to tilt without hindrance and without risk of blocking relative to the support point, even if the valve's individual ! stands are not manufactured with very precise tolerances.
15 I henhold til en særlig enkel og dermed hensigts mæssig udførelsesform -udgøres de nævnte midler til tilbageholdelse af pladen på dækslet af en ledforbindelse mellem pladen og dækslet. Denne ledforbindelse giver mulighed for både at opnå vipning og.tilbageholdelse af 20 pladen. Eksempelvis kan pladen være udformet med ben, der danner lejer for en på dækslet monteret, drejelig aksel*. Ledforbindelsesakslen er dog fortrinsvis tilvejebragt ud i ét med dækslet, navnlig ved støbning, medens pladen ved midler af passende form, f.eks. elastiske 25 læber, snaplåses til akslen. Naturligvis kan ledforbindelsesakslen udformes sammen med pladen, f.eks. ved støbning, medens dækslet ved hjælp af elastiske læber snaplåses til akslen. Når pladen vipper, kan membranen, som er i kontakt med pladen, udsættes for indre spændin-30 ger, som er uhensigtsmæssige for en fin regulering. For at afhjælpe dette er det hensigtsmæssigt, at pladen er ledforbundet med dækslet, således at det udover vippebevægelsen har en yderligere bevægelsesfrihedsgrad, navnlig bevægelse i retning vinkelret på aksen. Dette 35 giver mulighed for tværgående justering af pladen for at svække kraftpåvirkningerne på membranen. Med henblik 3According to a particularly simple and thus convenient embodiment, said means for holding the plate to the cover is constituted by a joint connection between the plate and the cover. This joint allows for both tilting and retaining of the plate. For example, the plate may be formed with legs forming a bearing for a rotatable shaft mounted on the cover *. However, the articulated shaft is preferably provided integrally with the cover, in particular by casting, while the sheet is by means of suitable form, e.g. elastic 25 lips, snap-lock to the shaft. Of course, the articulated joint shaft can be formed together with the plate, e.g. by casting, while the cover is snap-locked to the shaft by means of elastic lips. As the plate tilts, the membrane which is in contact with the plate may be subjected to internal stresses which are unsuitable for fine regulation. To remedy this, it is desirable that the plate be articulated with the cover so that, in addition to the tilting movement, it has a further degree of freedom of movement, in particular movement in a direction perpendicular to the axis. This allows transverse adjustment of the plate to weaken the force effects on the membrane. For the purpose 3
DK 163386 BDK 163386 B
herpå kan der eksempelvis anvendes aflange lejer, hvis storakse strækker sig i retning vinkelret på ventilens akse, og hvori ledforbindelsesakslen placeres.for this, elongated bearings can be used, for example, whose major axis extends in a direction perpendicular to the axis of the valve and in which the articulated shaft is placed.
Samlingsoperationerne forenkles også ved, at der 5 i det kammer, der rummer fjederen, findes midler til begrænsning af pladens vippebevægelse i den af fjederkraften fastlagte retning. Herved opnår man sikkerhed for, at fjederen ikke kan forlade kammeret, hvis man vipper pladen for meget. Dette har ingen indvirkning på regule-10 ringen, eftersom det til regulering fornødne område for vippebevægelse af membranen er relativt lille. Med disse midler til begrænsning af pladens vippebevægelse er der sikkerhed for korrekt samling af enheden, indbefattende dækslet og pladen; på huset. Disse midler til begræns-15 ning af pladens vippebevægelse kan udgøres.af et på dækslet tilvejebragt stop, der befinder sig på den anden side af støttepunktet.i forhold til fjederen, hvilket stop også kan være tilvejebragt på pladen og komme i, an- i læg mod dækslet eller også ved en sådan udformning af 20 daskslet, at der er begrasnset pladevipning.The assembly operations are also simplified by the fact that in the chamber containing the spring there are means for limiting the tilting movement of the plate in the direction determined by the spring force. This ensures that the spring cannot leave the chamber if you tilt the plate too much. This has no effect on the control, since the area required for control of the tilting movement of the membrane is relatively small. With these means for limiting the tilting movement of the plate, there is a guarantee of proper assembly of the unit, including the cover and the plate; on the house. These means for limiting the tilting movement of the plate may be constituted by a stop provided on the cover which is on the other side of the support point relative to the spring, which stop may also be provided on the plate and come in and out. place against the cover or also in such a configuration of the cover that there is limited sheet tilt.
Da membranen ingen fast forbindelse har med pladen, kan man under samleoperationerne bedre se beliggenheden af de enkelte dele i det indre af det kammer, der indeholder fjederen, og det er nemmere at få en kor-25 rekt placering af huset i forhold til dækslet uden behov for mærker. Denne adskillelse mellem membranen og pladen giver mulighed for at montere membranen uden indre spændinger. Energien til bevægelse af membranen er lavere. Reguleringen er finere og ventilens funktion bedre. Da 30 membranen er mere følsom, kan den også have mindre dimension. Reduktionsventilen kan have mindre dimensioner. Samlingen foregår ved, at man samler dækslet og pladen, som holder fjederen tilbage, i en enhed, der efter indsætning af membranen placeres på huset. På denne måde 35 afskaffes operationen til fast forbindelse mellem membranen og pladen.Since the diaphragm has no fixed connection to the plate, during the assembly operations it is better to see the location of the individual parts in the interior of the chamber containing the spring, and it is easier to get a correct positioning of the housing relative to the cover without need for brands. This separation between the diaphragm and the plate allows the diaphragm to be mounted without internal stresses. The energy to move the membrane is lower. The control is finer and the function of the valve better. As the membrane is more sensitive, it may also have less dimension. The reduction valve may have smaller dimensions. The assembly is done by assembling the cover and plate holding the spring back into a unit which, after insertion of the diaphragm, is placed on the housing. In this way, the operation for firm connection between the diaphragm and the plate is abolished.

I henhold til en udførelsesform omfatter ventilen en anden fjeder, der har mindre fjederkraft end førstnævnte fjeder, og som er således indrettet, at den på den del af membranen, der skal presses på mundingen, ud-5 øver en kraf-t, der søger at fjerne membranen fra mundingen .According to one embodiment, the valve comprises a second spring which has less spring force than the first spring and is arranged so that it exerts a force on the part of the membrane to be pressed on the mouth. removing the membrane from the mouth.
I henhold til fig. 1 i nævnte US patentskrift nr.According to FIG. 1 of said US Pat.
3 900 045 er det kendt at anvende en fjeder til dette formål. Denne fjeder virker dog også som hovedfjeder.3 900 045, it is known to use a spring for this purpose. However, this spring also acts as a main spring.
10 Som følge heraf er der i forhold til ledforbindelsesakslen en kort momentarm, hvorfor fjederen ikke virker så effektivt som hovedfjederen. Da fjederen skal være kraftig, er samlingsarbejdet besværligt. Ved i henhold til opfindelsen at anvende to separate fjedre, den ene 15 til regulering, den anden til at forhindre membranen i at sætte sig fast på mundingen, afhjælper man disse u-1emper.As a result, there is a short torque arm relative to the articulated shaft, so the spring does not work as efficiently as the main spring. Since the spring must be strong, the assembly work is cumbersome. By using two separate springs according to the invention, one for regulation, the other for preventing the membrane from attaching to the mouth, these disadvantages are remedied.
Når en reduktionsventil i henhold til opfindelsen bruges som hane, kan den hensigtsmæssigt være udstyret 20 med et greb, der i hovedsagen har samme rotationsakse som ventilens akse. Brugeren forventer at finde en reduktionsventils hane i denne stilling og er i stand til umiddelbart at betjene den på samme måde som en konventionel hane. For at bibeholde denne brugervenlige for-25 del ved en reduktionsventil i henhold til opfindelsen er denne ventil udformet med et ben, der fortrinsvis strækker sig parallelt med aksen, og som vipper sammen med pladen og har forbindelse med denne ved ledforbindelsespunktet, samt en mekanisme til forskydning' af den 30 frie ende af benet i en bevægelse, der' har en komposant vinkelret på aksen. Herved opnår man en vipning af pladen og dermed af den i kontakt med pladen værende mem- i bran ved rotation af mekanismen med håndgrebet, og dette opnås uden behov for alt for stor betjeningskraft fra 35 brugeren, eftersom det kraftoverførende ben strækker sig fra støttepunktet, hvorfor den af håndgrebet påførte'Conveniently, when a reduction valve according to the invention is used as a tap, it may be provided with a grip having substantially the same axis of rotation as the axis of the valve. The user expects to find a reducing valve cock in this position and is able to operate it immediately in the same way as a conventional cock. In order to maintain this user-friendly advantage of a reduction valve according to the invention, this valve is formed with a leg which preferably extends parallel to the axis and which flips with the plate and communicates with it at the link point, as well as a mechanism for displacement 'of the 30 free end of the leg in a motion having' a component perpendicular to the axis. This results in tilting of the plate and thus of the membrane in contact with the plate by rotation of the mechanism by the handle, and this is achieved without the need for excessive operating force from the user as the power transmitting leg extends from the support point, why the one applied by the handle '

Dette ville ikke være tilfældet, hvis benet havde forbindelse med pladen i større afstand fra'støttepunktet.This would not be the case if the bone was connected to the plate at a greater distance from the supporting point.
5 ' Opfindelsen forklares nærmere i dét følgende under henvisning til den skematiske tegning, hvor fig. 1 viser et snit gennem en reduktionsventil i henhold til opfindelsen, fig. 2 et snit langs snitlinien II-II i fig. 1, og 10 fig. 3-6 diverse udførelsesformer.The invention is further explained in the following with reference to the schematic drawing, in which fig. 1 is a section through a reduction valve according to the invention; FIG. 2 is a sectional view along section line II-II of FIG. 1 and 10 in FIG. 3-6 miscellaneous embodiments.
Den i fig. 1 og 2 viste gasreduktionsventil omfatter en membran 1, hvis overside er i kontakt med en plade 2 uden at have fast forbindelse med denne, og hvis kant er fastklemt mellem et hus 3 og et dæksel 4 15 ved indfalsning som vist ved 5. Huset 3 og dækslet 4 har i hovedsagen form som omdrejningslegemer i forhold til aksen X, X'. Membranen 1 deler det af huset 3 og dækslet 4 afgrænsede rum op i to kamre A, B.The FIG. 1 and 2, the gas reduction valve comprises a diaphragm 1, the upper side of which contacts a plate 2 without having a fixed connection therewith, and the edge of which is clamped between a housing 3 and a cover 4 15 by folding in as shown at 5. The housing 3 and the cover 4 is generally in the form of revolutions relative to the axis X, X '. The diaphragm 1 divides the space delimited by the housing 3 and the cover 4 into two chambers A, B.
Det øvre kammer A indeholder pladen 2 og en i af-20 stand fra aksen X, X' værende fjeder 6, hvis ene ende støtter sig til toppen af dækslet 4, og hvis anden ende trykker på pladen 2. Det nedre kammer B har forbindelse med en tilgangsstuds 7 og med en afgangsstuds 8, og pladen 2 er drejeligt lejret på en ledforbindelses-25 aksel 9 i to lejer 10, der er støbt ud i ét med dækslet 4. Akslen 9 danner et støttepunkt mellem fjederen 6 og tilgangsstudsen 7's munding i kammeret B, således at pladen 2 kan vippe og dermed bringe membranen 1 til at ligge an mod tilgangsstudsen 7's mun-30 ding eller bort derfra. En fjeder 11, der har mindre fjederkraft end fjederen 6, omgiver tilgangsstudsen 7's munding og forhindrer membranen i at sætte sig fast på mundingen. På pladen 2 og ved støttepunktet findes der et ben 12, der strækker sig parallelt med aksen X, X'.The upper chamber A contains the plate 2 and a spring 6 spaced from the axis X, X ', one end of which supports the top of the cover 4 and the other end of which presses the plate 2. The lower chamber B is connected with an inlet nozzle 7 and with an outlet nozzle 8, and the plate 2 is pivotally mounted on a hinge connection shaft 9 in two bearings 10 cast integrally with the cover 4. The shaft 9 forms a support point between the spring 6 and the inlet nozzle 7 in the chamber B so that the plate 2 can tilt and thereby cause the membrane 1 to abut the mouth of the inlet nozzle 7 or away from it. A spring 11 having less spring force than the spring 6 surrounds the mouth of the inlet nozzle 7 and prevents the diaphragm from attaching to the mouth. On the plate 2 and at the supporting point there is a leg 12 extending parallel to the axis X, X '.

Denne kraft har tendens til at bringe pladen til at vippe i den trigonometriske retning og til dermed at presse membranen 1 mod tilgangsstudsen 7's munding.FIG. 6 shows an embodiment of the pressure reducing valve. A cam 19 on the spirit valve 14 of the reduction valve abuts against the vertical branch 20 of a spring formed in the center, with a winding surrounding the rotary shaft so that the plate 2 can tilt relative to the cover 4, while The opposite of the spring, in the generally horizontal branch 21, exerts spring force on the plate 2. This force tends to cause the plate to tilt in the trigonometric direction and thus to push the diaphragm 1 against the mouth of the access stud 7.

En sådan enhed holdes samlet uden behov for kraftpåvirkning til at holde bestanddelene sammen.The method of producing the reducing valve according to FIG. 4 is intended to first assemble the plate 2, the cover 4 and the spring 6 into a unit, after which this unit is mounted on the housing 3 without preliminary folding in, whereupon folding is carried out. Such a unit is held together without the need for force to hold the components together.
