Opfindelsen angår en gasreduktionsventil af den i krav l's indledende del nævnte.The invention relates to a gas reduction valve of the preamble of claim 1.
Fra beskrivelsen til US patent nr. 3 900 045 kender man en gasreduktionsventil med en membran, hvis 5 ene side er fast forbundet med en plade, og som langs omkredsen er fastklemt mellem et hus og et dæksel, der begge i hovedsagen har form som omdrejningslegeme. Membranen deler rummet mellem huset og dækslet op i to kamre. Det ene kammer rummer pladen og en i afstand fra 10 omdrejningsaksen beliggende fjeder, der trykker på pladen. Det andet kammer står i forbindelse med en udgangsstuds og med en indgangs s tuds, på hvis munding membranen presses, når pladen vipper om et punkt mellem fjederen og mundingen. Dette støttepunkt og fjederen 15 befinder sig fortrinsvis på hver sin side af aksen. Da støttepunktet befinder sig på dækslet, medens indgangsstudsen befinder sig på huset, er der behov for meget præcis montering af dækslet på huset, eftersom dækslet ikke alene har til funktion at fastklemme membranen og 20 holde fjederen - for hvilken funktion placeringen af dækslet på huset kan være upræcis og vinkelmæssigt foretages vilkårligt i forhold til aksen - men også til funktion at placere støttepunktet rigtigt i forhold til indgangsstudsens munding, hvilken funktion nu kræver 25 præcision både i vinkelretning og i ventilens akseretning. Hvis støttepunktet i ventilens akseretning placeres forskudt fra den position, det bør have, vil membranen ligge an mod indgangsstudsens munding i et plan, der hælder for lidt eller for meget, hvilket fører til 30 dårlig tætlukning, og selv om der skulle være tætlukning, vil fjederkraften være for stor eller for svag i forhold til den kraft, ventilen er beregnet til. Den gastryk-børværdi, ved hvilken ventilen skal spærre for gastilførslen, vil i så fald ikke blive respekteret.From the specification of US Patent No. 3,900,045, there is known a gas reduction valve with a diaphragm, the one side of which is firmly connected to a plate and which is clamped along the circumference between a housing and a cover, both of which generally have the shape of a rotating body. . The diaphragm divides the space between the housing and the cover into two chambers. One chamber holds the plate and a spring located at a distance from the axis of rotation 10 presses the plate. The second chamber communicates with an outlet nozzle and with an inlet s nozzle on whose orifice the diaphragm is pressed as the plate tilts about a point between the spring and the orifice. This support point and the spring 15 are preferably located on either side of the axis. Since the support point is on the cover, while the input socket is on the housing, very precise mounting of the cover on the housing is required, since the cover not only functions to clamp the diaphragm and hold the spring - for which function the position of the cover on the housing can to be inaccurate and angular to be done arbitrarily in relation to the axis - but also to function to position the support point correctly in relation to the mouth of the inlet nozzle, which function now requires precision both in the angular direction and in the axis direction of the valve. If the support point in the valve direction of the valve is positioned offset from the position it should have, the diaphragm will abut against the mouth of the entrance nozzle in a plane that is inclined too little or too much, leading to poor closure, and even if there is to be closed, the spring force is too great or too weak in relation to the force for which the valve is intended. In this case, the gas pressure setpoint at which the valve is to block the gas supply will not be respected.
35 Opfindelsen afhjælper dise ulemper ved hjælp af en reduktionsventil, hvor præcisionen i den indbyrdesThe invention solves these disadvantages by means of a reduction valve, the precision of which is mutually
DK 164373 BDK 164373 B
2 placering af støttepunktet og mundingen eller sædet på indgangsstudsen, og den heraf følgende fordel ved pålidelig aflukning og overholdelse af det foreskrevne lukketryk, ikke længere er afhængige af monteringen af 5 dækslet på huset.2, the location of the support point and the mouth or seat on the entrance socket, and the consequent advantage of reliable closure and compliance with the prescribed closing pressure, no longer depend on the mounting of the cover on the housing.
Gasreduktionsventilen ifølge opfindelsen omfatter en membran, hvis ene side er fast forbundet med en plade, og som langs omkredsen er fastklemt mellem et hus og et dæksel, der begge i hovedsagen har form som 10 omdrejningslegeme, hvilken membran deler rummet mellem huset og dækslet op i to kamre, hvoraf det ene rummer en fjeder, der trykker på membranen, medens det andet kammer står i forbindelse med en udgangsstuds og med en indgangsstuds, på hvis munding pladen presses, når 15 pladen vipper om et støttepunkt mellem fjederen og membranen, idet støttepunktet og fjederen fortrinsvis befinder sig på hver sin side af aksen. Denne ventil er ejendommelig ved midler til at tilbageholde pladen i huset.The gas reduction valve according to the invention comprises a diaphragm, one side of which is firmly connected to a plate, which is clamped along the circumference between a housing and a cover, both of which generally have the shape of a rotating body, which diaphragm divides the space between the housing and the cover. two chambers, one of which holds a spring pressing the diaphragm, while the other chamber communicates with an outlet nozzle and with an inlet nozzle, on whose mouth the plate is pressed as the plate tilts about a support point between the spring and the diaphragm, the support point and the spring is preferably located on either side of the axis. This valve is peculiar by means of holding the plate in the housing.
20 Den relative beliggenhed af støttepunktet på pladen og mundingen i huset vil således bestemmes u-afhængigt af dækslet. Monteringen af dækslet kan således ikke længere have indflydelse på denne relative placering, som under fremstillingen direkte sikres, når 25 blot pladen monteres i huset.Thus, the relative location of the support point on the plate and the mouth of the housing will be determined independently of the cover. Thus, the mounting of the cover can no longer affect this relative location, which is directly ensured during manufacture when the plate is simply mounted in the housing.
I henhold til en særlig enkel foretrukken udførelsesform, kan midlerne til tilbageholdelse af pladen i huset udgøres af en ledforbindelse mellem pladen og huset. En sådan ledforbindelse giver mulighed for 30 både at opnå vipning af pladen og holde pladen tilbage. Eksempelvis kan pladen være udformet med ben, der danner leje for en i huset anbragt drejetap. Ledforbindelsesakselen er dog fortrinsvis tilvejebragt sammen med huset, f.eks. ved støbning, og pladen snaplåses til 35 denne aksel, eksempelvis ved en passende udformning med fjedrende læber. Det er dog klart at ledforbindelses-According to a particularly simple preferred embodiment, the means for retaining the plate in the housing may be constituted by a joint connection between the plate and the housing. Such a joint allows 30 to both tilt the plate and hold the plate back. For example, the plate may be formed with legs forming a bearing for a pivot pin located in the housing. However, the hinge shaft is preferably provided with the housing, e.g. by casting, and the plate is snap-fastened to this shaft, for example, by a suitable configuration with resilient lips. However, it is clear that
DK 164373 BDK 164373 B
3 akselen også kan tilvejebringes sammen med pladen, navnlig ved støbning, og snaplåses i fjedrende læber på selve huset. Når pladen vipper, kan membranen i kontakt med pladen blive udsat for indre spændinger, der 5 er uhensigtsmæssige for en finindstilling. For at afhjælpe dette, er det hensigtsmæssigt udover vippebevægelsen, at tilgodese en vis grad af bevægelsesfrihed, navnlig i retning vinkelret på akselen. Dette giver mulighed for tværgående justering af pladen for at mod-10 virke spændingerne i membranen. Med henblik herpå kan drejetappen lejres i aflange lejeåbninger, hvis storakse strækker sig vinkelret på ventilens akse.The shaft 3 can also be provided together with the plate, especially by casting, and snap into resilient lips on the housing itself. As the plate tilts, the membrane in contact with the plate may be exposed to internal stresses which are inappropriate for a fine tuning. To remedy this, in addition to the tilting motion, it is appropriate to accommodate a certain degree of freedom of movement, especially in the direction perpendicular to the shaft. This allows transverse adjustment of the plate to counteract the stresses in the membrane. To this end, the pivot pin can be mounted in elongated bearing openings whose major axis extends perpendicular to the axis of the valve.
Opfindelsen forklares nærmere i det følgende under henvisning til den skematiske tegning, hvor 15 fig. 1 viser et snit gennem en ventil ifølge opfindelsen, og fig. 2 en del af denne ventil.The invention is explained in more detail below with reference to the schematic drawing, in which FIG. 1 shows a section through a valve according to the invention, and FIG. 2 part of this valve.
Den viste gasreduktionsventil omfatter en membran 1 af elastomermateriale. Denne membran 1 er 20 fast forbundet med en plade 2. Membranen l's omkreds er fastklemt mellem et hus 3 og et dæksel 4, begge udformet i hovedsagen som omdrejningslegemer med akse XX'. Membranen deler rummet mellem huset 3 og dækslet 4 op i to kamre A, B. Kammeret A på dæk- 25 selsiden rummer en fjeder 6 i en vis afstand fra ak sen XX' og den ene ende af fjederen ligger an mod dækslet 4, medens den anden ende af fjederen presser membranen ud i retning mod kammeret B. Dette kammer står i forbindelse med en indgangsstuds 7 og med en 30 udgangsstuds 8. Den med membranen 1 forbundne plade 2 er drejeligt lejret ved en drejetap 9 i to lejer 10, som er tilvejebragt ved støbning sammen med huset 3. Drejetappen 9 danner støttepunkt mellem fjederen 6 og mundingen på indgangsstudsen 7 i kammeret B 35 således, at pladen 2 og membranen 1 kan vippe, hvorved pladen presses mod mundingen på indgangsstudsen 7 eller fjernes derfra.The gas reduction valve shown comprises a membrane 1 of elastomeric material. This diaphragm 1 is firmly connected to a plate 2. The circumference of the diaphragm 1 is clamped between a housing 3 and a cover 4, both formed essentially as rotary bodies with axis XX '. The diaphragm divides the space between the housing 3 and the cover 4 into two chambers A, B. The chamber A on the cover side accommodates a spring 6 at a certain distance from the shaft XX 'and one end of the spring abuts against the cover 4, while the other end of the spring pushes the diaphragm towards the chamber B. This chamber communicates with an inlet nozzle 7 and with an outlet nozzle 8. The plate 2 connected to the diaphragm 1 is pivotally mounted at a pivot 9 in two bearings 10 which is provided by casting together with the housing 3. The pivot pin 9 forms a supporting point between the spring 6 and the mouth of the inlet spout 7 in chamber B 35 so that the plate 2 and the membrane 1 can tilt, thereby pressing the plate against the mouth of the entrance spout 7 or being removed therefrom.
