(74) Fuldmægtig under sagens behandling:(74) Plenipotentiary in the proceedings:

Ingeniørfirmaet Hofman-Bang & Boutard._ (54) Ekspansionshane til flaskegasbeholder.Hofman-Bang & Boutard Engineering Company._ (54) Bottle gas expansion tank.

Opfindelsen omhandler en ekspansionshane til flaskegasbeholdere og af den i krav l's indledning angivne art.The invention relates to an expansion valve for bottle gas containers and of the kind specified in the preamble of claim 1.

I de kendte ekspansionshaner af denne art løftes ventilklappen mere eller mindre bort fra ventilsædet, svarende til det på membranen af dennes udligningsfjeder udøvede tryk, ved hvis ophør klappen trykkes helt ind imod sædet. Det er dog vanskeligt helt at ophæve fjedertrykket, fordi fjederen ved drejning af manøvreknappen kan blive forspændt og derved forfalske nøjagtigheden af trykformindskelsen, når fjederen atter går i indgreb med membranen.In the known expansion taps of this kind, the valve flap is lifted more or less away from the valve seat, corresponding to the pressure exerted on the diaphragm by its counterbalancing spring, at the end of which the flap is pressed fully against the seat. However, it is difficult to completely cancel the spring pressure because the spring can be biased by turning the maneuver button, thereby falsifying the accuracy of the pressure reduction as the spring engages with the diaphragm.

2 U32362 U3236

Opfindelsen har til formål at afhjælpe denne ulempe og tilvejebringe en ekspansionshane af den angivne art, hvor nøjagtigheden af trykformindskelsen ikke kan ændres ved afspærring og genoptagelse af gasstrømningen.The invention has for its object to alleviate this disadvantage and to provide an expansion valve of the specified type, where the accuracy of the pressure reduction cannot be changed by shut-off and resumption of the gas flow.

Dette opnås ifølge opfindelsen ved en konstruktion af den i krav l’s kendetegnende del angivne art. Herved tilvejebringes der en fast, ikke dejusterbar regulering, hvor ventilklappen føres til lukkestillingen af returfjederen uden at skulle overvinde de lukkebevægelsen modvirkende kræfter fra udligningsfjederen. Manøvreknappen har to distinkte stillinger: lukkestillingen eller åbenstillingen uden usikre mellemstillinger, og man undgår de konventionelle fastspændingsorganer i form af skruer, stifter eller nitter.This is achieved according to the invention by a construction of the nature of the characterizing part of claim 1. This provides a fixed, non-adjustable control where the valve flap is guided to the closing position of the return spring without having to overcome the closing movement counteracting forces from the equalizing spring. The maneuver button has two distinct positions: the closing position or the open position without uncertain intermediate positions, and the conventional clamping means in the form of screws, pins or rivets are avoided.

Ekspansionshanen ifølge opfindelsen kan samtidigt fungere som fluidumhane ved en kvart omdrejning af manøvreknappen.The expansion valve according to the invention can simultaneously act as a fluid valve at a quarter turn of the control knob.

Yed den i krav 2 angivne opbygning opnås en simpel fastholdelse af alle de indgående styreorganer ved indklinkning, hvorved manøvreknappen bliver frit drejelig og ikke kan afmonteres af brugeren.In accordance with the structure of claim 2, a simple retention of all the incoming control means is achieved by the click-in, whereby the control knob becomes freely rotatable and cannot be removed by the user.

Ved den i krav 3 angivne opbygning muliggøres en længdeforskydning af det fjederunderstøttede legeme samtidig med dettes påtrykte drejning.In the structure set out in claim 3, a longitudinal displacement of the spring-supported body is possible at the same time as its applied rotation.

Ved den i krav 4 angivne trepunktsophængning af støttelegemet opnås en simpel og positionspræcis montage af støttelegemet, der sikrer dette imod forskydning.The three-point suspension of the support body as specified in claim 4 achieves a simple and precise positioning of the support body, which ensures this against displacement.

Ved de i krav 5 og 6 angivne udformninger af skålen og dennes holdeorgan opnås en simpel arretering af skålen i åben eller lukket ventilstilling og en sikker positionering af holdeorganet.The configurations of the bowl and its holding means according to claims 5 and 6 provide a simple arrangement of the bowl in the open or closed valve position and a safe positioning of the holding means.

Ved den i krav 7 angivne opbygning opnås, at ventilspindelen kan monteres uafhængigt af membranen og den øverste del af ekspansionshanen, samt at den af returfjederen forspændte ventilklap kan aktiveres af membranen uden fast forbindelse med ventilspindelen.In the structure of claim 7, it is achieved that the valve stem can be mounted independently of the diaphragm and the upper part of the expansion valve, and that the valve flap which is biased by the return spring can be actuated by the diaphragm without fixed connection to the valve stem.

Ved de i krav 8 og 9 angivne fastholdelser af pakringen undgås, at pakringen forbliver i berøring med ventilsædet, når ventilspindelen aktiveres af membranen.The retaining ring of the sealing ring according to claims 8 and 9 prevents the sealing ring from remaining in contact with the valve seat when the valve stem is activated by the diaphragm.

Opfindelsen forklares nærmere nedenfor i forbindelse med tegningen, hvor: fig. 1 viser et snit igennem en ekspansionshane ifølge opfindelsen i åben stilling, fig. 2 en udtrukket perspektivisk afbildning af mekanismen til afbrydelse og retablering af gasstrømmen, og fig. 3 en detalje af låsemekanismen på fig. 2.The invention is further explained below in connection with the drawing, in which: FIG. 1 shows a section through an expansion valve according to the invention in an open position; FIG. 2 is an exploded perspective view of the gas flow interruption and recovery mechanism; and FIG. 3 shows a detail of the locking mechanism of FIG. 2nd

Ekspansionshanen har en krop 1 med en gevindmuffe 2, der kan ind-skrues i en flaske med flydende gas, en tætslutningsdannende pakning 3 og et rørstykke 4, hvormed hanen kan tilsluttes en aftapningsbeholder. I en udboring 5 i muffen 2 er der med prespasning lejret kroppen af et sæde 6 for en ventilklap 7, som er fastgjort til en spindel 8, der frit kan glide i en udboring 9 i sædet. En fjeder 10 udøver på ventilklappen 7 et tryk i trykretningen p for gassens indgang og søger at trykke klappen imod sædet. En tværgående boring 11 i sædekroppen 6 muliggør for gassen i åben stand af klappen at strømme ind i et ekspansionskammer 12, som foroven afgrænses af en elastisk membran 13· Membranen 13, som er fastklemt imellem kroppen 1 og et dæksel 14, er i fast forbindelse med en skål 15 og forbundet med spindelen 8.The expansion cock has a body 1 with a threaded sleeve 2 which can be screwed into a liquid gas bottle, a tightly sealing gasket 3 and a pipe piece 4 with which the cock can be connected to a drain container. In a bore 5 in the sleeve 2, the body is secured with a press fit by a seat 6 for a valve flap 7, which is attached to a spindle 8 which can freely slide in a bore 9 in the seat. A spring 10 exerts on the valve flap 7 a pressure in the pressure direction p for the gas inlet and seeks to push the flap against the seat. A transverse bore 11 in the seat body 6 allows the gas in the open position of the flap to flow into an expansion chamber 12, which is delimited at the top by an elastic membrane 13 · The membrane 13 which is clamped between the body 1 and a cover 14 is fixedly connected with a bowl 15 and connected to the spindle 8.

Ekspansionshanen har en hul manøvreknap 16, som ved en rille 17 på sin indervæg er indklinket på et sidefremspring 18 på en bøsning 19, som udgør den øverste del af dækselet 14. En tap 20 i den underste del af knappens sidevæg indgriber i en cirkulær rille 21 i dækselet 14, hvilket begrænser knappens drejningsvandring til omkring 90°. Knappen 16 sidder på en riflet central aksel 22, hvis frie ende rager forbi det nederste parti af knappens sidevæg.The expansion tap has a hollow maneuver button 16 which, by a groove 17 on its inner wall, is clamped on a lateral projection 18 on a sleeve 19 which forms the upper part of the cover 14. A pin 20 in the lower part of the button's side wall engages in a circular groove. 21 in the cover 14, which limits the rotation of the button to about 90 °. Button 16 sits on a ribbed central shaft 22, the free end of which extends past the lower portion of the button side wall.

I dækselet 14 er der uformet tre hældende ramper 23, imod hvilke der kan anligge tre tapper 24 i form af en skråflade på et legeme 25» der virker som understøtning for en udligningsfjeder 26. Legemet 25 har to cylindriske koaksiale vægge 25a og 25b, som forneden er broforbundet over en cirkulær bund 25c. Den indvendige cylinder 25a er udformet med et øverste parti 25d med en åbning 25e hvis tværsnitsprofil svarer til profilet af akselen 22 af manøvreknappen 16, medens den udvendige cylinder 25b foroven bærer de radiale tapper 24» som er ligeligt fordelt langs omkredsen. Akselen 22 indgriber i åbningen 25e med en frigang, der svarer omtrent til den dobbelte frigang af den, som muliggøres af den nedenfor omtalte tilbagedrejning WC% til medførelse af legemet 25 i samro ta ti on med knappen 16, alt imedens legemet 25 frit kan glide langs akselen.In the cover 14 there are formed three sloping ramps 23 against which three pins 24 may be in the form of an inclined surface of a body 25 which acts as a support for a compensating spring 26. The body 25 has two cylindrical coaxial walls 25a and 25b which below is the bridge joint over a circular bottom 25c. The inner cylinder 25a is formed with an upper portion 25d with an opening 25e whose cross-sectional profile corresponds to the profile of the shaft 22 of the maneuver button 16, while the outer cylinder 25b carries the radial pins 24 »which are evenly distributed along the circumference. The shaft 22 engages in the opening 25e with a clearance approximately equal to the double clearance of that made possible by the retraction WC% referred to below to cause the body 25 in co-op ten with the button 16, while the body 25 can slide freely along the shaft.

Udligningsfjederen 26, er lejret i det cirkulære mellemrum imellem legemet 25's indervæg 25a og ydervæg 25b. En skål 27 af udstanset tynd plade udgør et overliggende anlæg for fjederen 26 og har en central åbning 27a» hvorigennem akselen 22 af knappen 16 kan passere med meget lille frigang. Skålen 27 fastholdes i den ønskede stilling af et holdelegeme 28, der ligeledes består af udstanset r* tynd plade, og som friktionsglider inden i dækselet 14 og ved en større eller mindre indtrykning muliggør at justere udligningsfjederen 26 til en nøjagtig værdi. Legemet 28 har et hul 28a, som muliggør en fri drejning af akselen 22 af knappen 16, og ombukkede lapper 28b ved legemets periferiske væg, hvilke lapper indgriber i riller 29 i dækselet 14 og orienterer legemet 28.The compensating spring 26 is mounted in the circular space between the inner wall 25a of the body 25 and the outer wall 25b. A plate 27 of punched-out thin plate forms an overlying abutment for the spring 26 and has a central opening 27a through which the shaft 22 of the button 16 can pass with very little clearance. The cup 27 is held in the desired position by a retaining member 28, which also consists of die cut thin plate and which frictionally slides inside the cover 14 and, by a larger or smaller indentation, allows the compensating spring 26 to be adjusted to an exact value. The body 28 has a hole 28a which allows free rotation of the shaft 22 by the button 16, and folded patches 28b at the circumferential wall of the body, which engages grooves 29 in the cover 14 and orientates the body 28.

Den øverste skål 27 har tre kugleformede oppresninger 27b, hvortil der svarer kugleformede oppresninger 28o og 28f med en indbyrdes vinkelforskydning på omkring 90° i holdelegemet 28, hvorved den overliggende skål 27 kan fastlåses til holdelegemetThe upper bowl 27 has three spherical grooves 27b, corresponding to spherical grooves 28o and 28f with an angular displacement of about 90 ° in the holding body 28, whereby the overlying bowl 27 can be locked to the holding body

28 i de på fig. 3 viste stillinger for lukning og åbning af manøvreknappen 16, hvis drejning imellem disse to stillinger medfører samtidig drejning af holdelegemet 28 og den overliggende skål 27. Skålen 27 muliggør for knappen 16 ved den svage frigang imellem åbningen 27a og akselen 22 at foretage en lille tilbagedrejning, når tappen 20 på knappen 16 er bragt i anslag mod bunden af rillen 21 i dækselet 14. Denne tilbagedrejning (C), som på fig. 3 er vist med stiplede linier for oppresningen 27b i skålen 27, virker til at skaffe frigang imellem knappens aksel 22 og fjederunderstøtningslegemet 25, hvorved dette kan glide fuldstændigt frit uden friktion.28 in the FIG. 3 for closing and opening the maneuver button 16, the rotation of which between these two positions results in simultaneous rotation of the holding body 28 and the overlying cup 27. The cup 27 enables the button 16 at the slight clearance between the opening 27a and the shaft 22 to make a slight retraction. , when the pin 20 of the button 16 is brought into contact with the bottom of the groove 21 in the cover 14. This retraction (C), as in FIG. 3 is shown in dotted lines for the upright 27b in the bowl 27, acts to provide clearance between the button shaft 22 and the spring support body 25, thereby allowing it to slide completely freely without friction.

I hanens lukkestilling ligger de tre tapper 24 på understøtningslegemet 25 an på oversiden af ramperne 23 i dækselet 14 i stillingen 23a. Legemet 25 antager da en opløftet stilling af en sådan art, at membranen 13 ikke længere underkastes virkningen af udligningsfjederen 26. Herved kan ventilklappen 7 ligge an imod ventilsædet 6 under påvirkning af returf jederen 10 og trykket af den ankommende gas. Oppresningeme 27b i skålen 27 ligger da i indgreb med oppresningeme 28f i holdelegemet 28.In the closing position of the male, the three pins 24 of the support body 25 lie on the upper side of the ramps 23 in the cover 14 in the position 23a. The body 25 then assumes an uplifted position such that the diaphragm 13 is no longer subjected to the action of the equalizing spring 26. Hereby, the valve flap 7 can abut against the valve seat 6 under the influence of the return spring 10 and the pressure of the oncoming gas. The uprights 27b in the bowl 27 then engage the uprights 28f in the holding body 28.

Ved drejning af manøvreknappen 16 imod den på fig. 1 viste åbne stilling af hanen medbringer knappens aksel 22 skålen 27 og frigør denne fra legemet 28. Samtidigt bevæger tapperne 24 på legemet 25 sig ned ad ramperne 23 og går til sidst fri af disse. Legemét 25 ligger da an imod membranen 13, og trykket fra udligningsfjederen 26 presser membranen nedefter. Spindelen 8 medbringer igen ventillegemet 7 og frigør det fra sædet. Drejningen af knappen 16 underkaster ikke fjederen 26 nogen vridning under denne manøvre.By turning the control knob 16 towards the one shown in FIG. 1, the shaft 22 of the button brings the cup 27 and releases it from the body 28. At the same time, the pins 24 on the body 25 move down the ramps 23 and eventually release them. The body 25 then abuts the diaphragm 13 and the pressure from the equalizing spring 26 presses the diaphragm downward. The spindle 8 again carries the valve body 7 and releases it from the seat. The rotation of the button 16 does not subject the spring 26 to any torsion during this maneuver.

Selv om manøvreknappen 16 er i åben stilling på fig. 1, er ventilknappen 7 vist i lukket stilling, idet lukningen er fremkaldt ved påvirkning af fluidets tryk i kammeret 12 på membranen 13.Although the control knob 16 is in the open position of FIG. 1, the valve button 7 is shown in the closed position, the closure being caused by the influence of the fluid pressure in the chamber 12 on the membrane 13.

På spindelen 8 af ventilklappen 7 er der prespasset og i en ønsket stilling blokeret en central bøsning 31 på en skål 30 af stål eller messing. I det indre af skålen 30 er der ved simpel adhæsion ved prespasning eller ved klæbning fastgjort en pakringOn the spindle 8 of the valve flap 7, a central bushing 31 on a steel or brass bowl 30 is blocked and in a desired position. In the interior of the bowl 30, by simple adhesion by pressing fit or by adhesive, a packing ring is attached
