Som vist i fig. 1-4 omfatter en ventil og en reguleringsanordning ifølge den foreliggende oppfinnelse et legeme eller As shown in fig. 1-4 comprises a valve and a regulation device according to the present invention a body or

hus 10 hvor det er anordnet fluktende porter 11 (hvorav bare den.'■"-'!>• house 10 where there are arranged floating gates 11 (of which only the.'■"-'!>•

ene er vist) . Huset 10 er utstyrt med endeflater 10a som gjør one is shown). The housing 10 is equipped with end surfaces 10a which make

det mulig å holde ventilen i stilling, f.eks. i en rørledning. it is possible to keep the valve in position, e.g. in a pipeline.

Portene 11 er anordnet i endene av en strømningskanal 13 og er The ports 11 are arranged at the ends of a flow channel 13 and are

atskilt fra hverandre ved hjelp av et seteorgankammer 14. Kammerveggens 14b endepartiér 14a har sirkelformet tverrsnitt for lett-vintere å kunne feste på dem et ventilstengeorgan som vil bli separated from each other by means of a seat member chamber 14. The end portions 14a of the chamber wall 14b have a circular cross-section so that a valve closing member can be attached to them, which will be

beskrevet nedenfor. Mellom endene har kammeret rektangulært tverrsnitt. Kammerets-lengdeakse danner fortrinnsvis en rett = vinkel-med husets 10 lengdeakse ...Som vist .-munner, kanalen -13 ut i kammeret 14. I kammerveggens 14b endepartiér 14a er det dannet omkretsspor 15 som er innrettet til å oppta endeflenser 16 på et fast anbrakt, hult organ 17 som danner et ventilstengeorgan. •' .• described below. Between the ends, the chamber has a rectangular cross-section. The longitudinal axis of the chamber preferably forms a straight = angle with the longitudinal axis of the housing 10 ... As shown, the channel 13 opens into the chamber 14. In the end portion 14a of the chamber wall 14b, a circumferential groove 15 is formed which is adapted to receive end flanges 16 on a fixed, hollow member 17 which forms a valve closing member. •' .•

Organet 17 inneholder og omslutter fullstendig en linseformet, dreibar kjerne 18 av stivt materiale. Kjernen 18 er utstyrt med tapplagre 19 i- hver ende, og disse er anbrakt i endelokk 20 i kammeret 14. Endelokkene. 20 holder også endene av ventil- " stengeorganet 17 på plass, og for dette formål er de utstyrt med en fals slik at det indre område av flensformete ender av stengeorganet 17 kan danne anlegg der. The member 17 contains and completely encloses a lens-shaped, rotatable core 18 of rigid material. The core 18 is equipped with journal bearings 19 at each end, and these are placed in end caps 20 in the chamber 14. The end caps. 20 also holds the ends of the valve closing member 17 in place, and for this purpose they are provided with a seam so that the inner area of the flange-shaped ends of the closing member 17 can form abutment there.

Som et alternativ til å anordne flenser 16 på endene av organet 17 for at de skal kunne holdes på plass, kan endene være plane og organet således være festet i stilling ved å feste det til de plane flater i endene av kammerveggen 14b. As an alternative to arranging flanges 16 on the ends of the member 17 so that they can be held in place, the ends can be flat and the member can thus be fixed in position by attaching it to the flat surfaces at the ends of the chamber wall 14b.

Det ene tapplager 19 er utstyrt med en forlengelse 21 iThe one journal bearing 19 is equipped with an extension 21 i

ett stykke, som rager utad fra det ene endelokk 20 for opptak-one piece, which projects outwards from one end cap 20 for recording

else av et ratt 22 eller liknende.Else of a steering wheel 22 or similar.

I bruk kan når ventilen er åpen slik som vist i fig. 1 ogIn use, when the valve is open as shown in fig. 1 and

4, medier i ledningen hvor ventilen er anbrakt passere utenom det linseformeté stengeorgan 17. For stenging av ventilen dreies 4, media in the line where the valve is located pass outside the lens-shaped closing member 17. To close the valve, turn

rattet 22, og når kjernen 18 dreier seg inne i stengeorganetthe steering wheel 22, and when the core 18 rotates inside the closing member

17, forandres dens konturer når hovedaksen for kjernen-18 for-17, its contours change when the main axis of the core-18 for-

skyves under dreiningen og reduserer således strømhingsrommet om stengeorganet 17 kontinuerlig inntil ventilen ettér en kvart omdreining av rattet 22 er stengt slik som vist i fig. 3. is pushed during the rotation and thus reduces the flow clearance around the closing member 17 continuously until the valve is closed after a quarter turn of the steering wheel 22 as shown in fig. 3.

Oppfinnelsen er selvsagt ikke begrenset til de ovenfor angitte detaljer. F.eks. kan det elastiske stengeorgars ytter- .'*/■ flate ha langsgående rifler som vist i fig.5 eller ha en annen kontur til dannelse av en meget effektiv seteflate som kan tryk- <j';, kes an mot kammerets.14 innerflate. Dessuten kan kammerets 14 innerflate være utstyrt med langsgående ribber eller spor for understøttelse av det elastiske stengeorgars 17 setedannende del . -.-når ventilen er i den stengte stilling. :f' ;Det er klart at endestengeorganene for kammeret 14 kan ha annen form enn det som er beskrevet ovenfor. F.eks. kan som vist ;i fig. 6 endestengeorganene ha formav påskrubare skiver 23, ;hvorav den ene i midten ér utformet med et blindhull 24 for opptakelse av tapplageret 19. Den andre endéskive 23 vil være utstyrt med en gjennomgående boring 25 for at en forlengelse.av ;tapplageret 19 kan løpe gjennom den for anbringelse av rattet '-' i'-* 22. Som det fremgår er begge skiver 23 falset for å frembringe sete for de riflete ender av kammerveggen 14a og for at inner- The invention is of course not limited to the above-mentioned details. E.g. can the outer surface of the elastic closing organ have longitudinal grooves as shown in Fig. 5 or have another contour to form a very effective seating surface which can be pressed against the inner surface of the chamber 14. In addition, the inner surface of the chamber 14 can be equipped with longitudinal ribs or grooves for supporting the seat-forming part of the elastic closing device 17. -.-when the valve is in the closed position. :f' ;It is clear that the end closing means for the chamber 14 can have a different shape than that described above. E.g. can, as shown in fig. 6, the end closing devices have the shape of screw-on discs 23, one of which in the middle is designed with a blind hole 24 for receiving the journal bearing 19. The other end disc 23 will be equipped with a through bore 25 so that an extension of the journal bearing 19 can run through the one for placing the steering wheel '-' i'-* 22. As can be seen, both discs 23 are rebated to produce a seat for the fluted ends of the chamber wall 14a and so that inner-

flaten av hver skive 23 kan danne fast anlegg mot den tilstøt- V the surface of each disc 23 can form a firm contact with the adjacent V

ende ende av stengeorganet 17. Det er klart at dersom det er ønskelig eller nødvendig kan rullelagre, nålelagre eller andre end end of the closing device 17. It is clear that if it is desirable or necessary, roller bearings, needle bearings or other

lagre 30 være anordnet (som vist i fig. 11) for anbringelse av kjernen .18 i kammeret 14, og i store ventiler kan det være anordnet kraftdrevne ventildrivanordninger som omfatter en kraftkilde 31 og f.eks. et gear 32 (som vist skjematisk i fig. 12) for dreining av kjernen 18 for åpning og stenging av ventilen. Dersom det er ønskelig er det anordnet lagre 30 (som vist) foran endene av kjernen 18. bearings 30 be arranged (as shown in Fig. 11) for placing the core .18 in the chamber 14, and in large valves there may be arranged power-driven valve drive devices comprising a power source 31 and e.g. a gear 32 (as shown schematically in fig. 12) for turning the core 18 for opening and closing the valve. If desired, bearings 30 (as shown) are arranged in front of the ends of the core 18.

Ifølge en annen modifikasjon er det anordnet en innret-ning for sikring av at kjernen 18 kan dreies relativt lettvint i det ikke dreibare stengéorgan 17, hvilket som angitt'ovenfor omslutter kjernen fullstendig. Mange alternative modifikasjoner av kjernen er mulig for å oppnå lettvint dreining.F.eks. kan kjernen 18 som vist i fig. 7 i enden av dens hovedakse være ut- According to another modification, a device is arranged to ensure that the core 18 can be rotated relatively easily in the non-rotatable closing member 17, which, as stated above, encloses the core completely. Many alternative modifications of the core are possible to achieve easy turning. E.g. can the core 18 as shown in fig. 7 at the end of its main axis be out-

styrt med ruller 26, eller som vist i fig. 8 med fjærbelastete blader 27. Ytterligere modifikasjoner kan f.eks. som vist i fig. controlled with rollers 26, or as shown in fig. 8 with spring-loaded blades 27. Further modifications can e.g. as shown in fig.

9 bestå i å anbringe hele kjernen 18 i en hylse 28 av materiale9 consist of placing the entire core 18 in a sleeve 28 of material

med liten friksjon, såsom PTFE (polytetrafluoretylen), eller somwith low friction, such as PTFE (polytetrafluoroethylene), or such

vist i fig. 10 kan kjernen 18 være utstyrt med smørespor for at smøremiddel under trykk kan føres mellom kjernen 18 og stengeorganet 17. shown in fig. 10, the core 18 can be equipped with lubrication grooves so that lubricant under pressure can be passed between the core 18 and the closing member 17.

Ifølge enda en annen modifikasjon som-spesielt er vist iAccording to yet another modification which is particularly shown in

fig. 13 er det anordnet en ventil som hovedsakelig består av et fig. 13, a valve is arranged which mainly consists of a

—legeme 100 og et stengeorgankammer 101 som er utformet i ett stykke med legemet og som har en lengdeakse som danner en rett vinkel med legemets 100 lengdeakse. Stengeorgankammérét er an- —body 100 and a closing member chamber 101 which is formed in one piece with the body and which has a longitudinal axis which forms a right angle with the longitudinal axis of the body 100. The closing organ chamber is an-

brakt sentralt i legemet 100. I legemet 100 er det utformet innvendig skruegjengete ender eller en annen type forbindelsesanord-ning som danner innløps- og utløpsporter 102. Til disse ender kan det være festet f.eks. to rør (ikke vist). brought centrally in the body 100. Internally screw-threaded ends or another type of connection device forming inlet and outlet ports 102 are formed in the body 100. To these ends there can be attached e.g. two pipes (not shown).

Det indre areal av stengeorgankammérét 101 kan være likt arealet av innløps- og utløpsportene 102, noe som særlig fremgårav"fig. 14, og i stillinger ved dets ender kan det være anordnet The inner area of the closing member chamber 101 may be equal to the area of the inlet and outlet ports 102, which is particularly apparent from "fig. 14, and in positions at its ends it may be arranged

fremspringene 107 på lagerbøssingene 108 er når de er anbrakt i sporene 106 innrettet til å hindre at bøssingene 108 dreies i forhold til stengeorgankammérét 101. Dessuten rager de kileformete fremspring 107 utad fra det som når bøssingene 108 er i.stilling danner en ytre flate 108a. Endene av fremspringene 107 hindrer sammen med blokker 109 på et betjeningselement 110 : bevegelse av elementet 110 til en bue på 90°. For dette formål er blokkene i betjeningselementet anbrakt slik at de når elementet 110 er i stilling ligger mellom sideflater 111 på de kileformete fremspring 107. Liknende blokker (ikke vist) som blokkene i betjeningsorganet 110 er dannet på en endekapsel 112 (se fig. 13 og 14) som i bruk er anbrakt på den motstående ende av -stengeorgankammérét 101. Endekapselen 112 og elementet 110 the protrusions 107 on the bearing bushings 108 are, when placed in the grooves 106, designed to prevent the bushings 108 from turning in relation to the closing member chamber 101. Moreover, the wedge-shaped protrusions 107 project outwards from what, when the bushings 108 are in position, forms an outer surface 108a. The ends of the projections 107 together with blocks 109 on an operating element 110 prevent: movement of the element 110 to an arc of 90°. For this purpose, the blocks in the operating element are placed so that when the element 110 is in position, they lie between side surfaces 111 of the wedge-shaped projections 107. Similar blocks (not shown) to the blocks in the operating element 110 are formed on an end cap 112 (see fig. 13 and 14) which in use is placed on the opposite end of the closing member chamber 101. The end cap 112 and the element 110

er begge utstyrt med en innadragende tapp 113 som er anbrakt i midten. Endekapselen 112 og elementet 110 samt deres tapper 113 er utboret i midten for opptakelse av festebolter 114.. Tappene 113 er innrettet til å anbringes i utsparinger 115 i are both equipped with an indenting pin 113 which is placed in the middle. The end cap 112 and the element 110 as well as their pins 113 are drilled in the middle for receiving fastening bolts 114. The pins 113 are designed to be placed in recesses 115 in

lagre 115a som vil bli beskrevet nedenfor. Inne i denne ventils elastiske stengéorgan 105 er det store 115a which will be described below. Inside this valve's elastic closing member 105 is

anbrakt en kjerne 116 som i motsetning til den kjerne 18 isom er fremstilt i ett stykke, i den ovenfor beskrevne ventil, består av tre elementer 117, 117a og 118. Kjernen fremgår best av fig. placed a core 116 which, in contrast to the core 18 which is produced in one piece, in the valve described above, consists of three elements 117, 117a and 118. The core is best seen in fig.

16. Som vist har elementene- 117, 117a samme form, og hvert består av lageret 115a og et par innbyrdes atskilte opptakelses-organer 119 som er utformet i ett stykke og som er innrettet til å oppta elementet 118. Opptakelsesorganet 119 har halvsirkel-formet ytre omriss i de ender som vender mot lagrene 115a, og dets tverrsnitt varierer i lengderetningen og ender i en rett-linjet kant. Atskilte, motsatt rettete flater 120 (se fig.; 14) på organene 119 i hvert par er flate selv om de i en utførelses-form ville kunne danne anlegg mot hverandre. Elementet 118 har slik lengde at det når det er anbrakt med sine endeområder mellom organene 119 er organenes 119 rettlinjete kanter atskilt, og lagrene 115a ér anbrakt i bøssingene 108 slik endeflater 121 på 16. As shown, the elements 117, 117a have the same shape, and each consists of the bearing 115a and a pair of mutually separated receiving means 119 which are designed in one piece and which are arranged to receive the element 118. The receiving means 119 has a semicircular shape outer outline at the ends facing the bearings 115a, and its cross-section varies in the longitudinal direction and ends in a rectilinear edge. Separate, oppositely directed surfaces 120 (see fig.; 14) on the members 119 in each pair are flat even though in one embodiment they could form contact with each other. The element 118 has such a length that when it is placed with its end areas between the bodies 119, the rectilinear edges of the bodies 119 are separated, and the bearings 115a are placed in the bushings 108 so that the end surfaces 121 of

organene 119 danner anlegg mot bøssingenes 108 endeflater. Bøs-singenes 108 endeflater ér avfaset i deres ytterkanter, for at en the bodies 119 form contact with the end surfaces of the bushings 108. The bushings' 108 end surfaces are chamfered at their outer edges, so that a

O-ringtetning (se fig..13 og 14) skal kunne anbringes mellom organene 119, bøssingene 108 og lagrene 115a. Elementet 118 har form som en flat stang med avrundete kanter 123. Elementets 118 ender har en sentral utboring og innvendig gjenget for opptakelse av boltene 114. O-ring seal (see fig..13 and 14) must be able to be placed between the bodies 119, the bushings 108 and the bearings 115a. The element 118 has the shape of a flat rod with rounded edges 123. The ends of the element 118 have a central bore and internal thread for receiving the bolts 114.

I bruk kan.ventilstengeorganet beveges fra en stilling hvor ventilen er åpen, slik det best fremgår av fig. 14, til en stilling hvor den er helt stengt, ved dreining av rattet 90° på samme måte som beskrevet ovenfor. In use, the valve closing member can be moved from a position where the valve is open, as can best be seen from fig. 14, to a position where it is completely closed, by turning the steering wheel 90° in the same way as described above.

Som følge av at størrelsen på tappene 113 er lik størrelsen på betjeningselementet 110 og endekapselen 112, kan disse anordninger anvendes på begge sider av stengeorgankammérét og betjen-ing av betjeningsorganet således foregå på den side av legemet 100 som er mest hensiktsmessig anbrakt for ventildrift. As a result of the size of the tabs 113 being equal to the size of the operating element 110 and the end cap 112, these devices can be used on both sides of the closing device chamber and operation of the operating device thus takes place on the side of the body 100 which is most conveniently placed for valve operation.

Dersom det er ønskelig kan betjeningsorganet erstattesIf desired, the operating device can be replaced

av en gearanordning slik at ventilen kan betjenes med en drivmotor som drives på liknende måte som det som er beskrevet ovenfor . of a gear device so that the valve can be operated with a drive motor which is operated in a similar way to that described above.

Ventilen ifølge oppfinnelsen har mange fordeler. Ikke minst som følge av at det anvendes et sete av elastomermateriale, kan det oppnås tett stenging av ventilen idet stengeorganet kan trykkes litt sammen mot flaten det danner anlegg mot, og således The valve according to the invention has many advantages. Not least due to the fact that a seat made of elastomer material is used, a tight closure of the valve can be achieved as the closing member can be pressed slightly against the surface it forms contact with, and thus

vil ikke små defekter i stengeorganet eller setet frembringe lekkasjebaner. Ved å bruke elastomermaterialer for stengeorganet small defects in the closing member or the seat will not create leakage paths. By using elastomeric materials for the closure member

behøver ikke bearbeidelsen av setet å være så nøyaktig som det som-er nødvendig ved fremstilling av et sete for et stivt ventilstengeorgan. Dessuten kan ventilen anvendes i røranlegg eller -systemer hvor skitne væsker skal håndteres, og i røranlegg eller -systemer hvor pulver og oppslemminger håndteres, idet stengeorganet, som har en relativt høy grad av elastisitet sammenliknet med et metallisk stengéorgan ikke vil bli ripet eller på annen måte bli ugunstig påvirket når partikler, granu-later eller liknende treffer det. the machining of the seat need not be as precise as that required in the manufacture of a seat for a rigid valve closing member. In addition, the valve can be used in pipelines or systems where dirty liquids are to be handled, and in pipelines or systems where powders and slurries are handled, as the closing member, which has a relatively high degree of elasticity compared to a metallic closing member, will not be scratched or otherwise way be adversely affected when particles, granules or the like hit it.

En annen fordel med de ovenfor beskrevne ventiler uten tetningsanordning er at ventilstengekammeret er helt isolert fra atmosfæren, og risikoen for forurensning er således utelukket. I tillegg, som følge av at ventilstengeorganet er fullstendig understøttet mot trykk, er rekken av polymermaterialer som kan Another advantage of the above-described valves without a sealing device is that the valve closing chamber is completely isolated from the atmosphere, and the risk of contamination is thus excluded. In addition, as a result of the valve closing member being fully supported against pressure, the range of polymer materials which can

Det faktum at ventilstengeorganet kan beveges fra en helt åpen til en helt stengt stilling med en kvart omdreining betyr at ventilen kan betjenes hurtig. Dessuten kan ventilen mellom helt stengt og helt åpen stilling reguleres meget fint, slik at ... ^. The fact that the valve closing member can be moved from a fully open to a fully closed position with a quarter turn means that the valve can be operated quickly. In addition, the valve can be adjusted very finely between fully closed and fully open positions, so that ... ^.

strømningsregulering av meget høy standard kan oppnås.flow regulation of a very high standard can be achieved.

Ventiler av den beskrevne type kan anvendes med vilkårlig orientering og ved horisontal orientering av ventilstengekammeret er ventilen' fullstendig selvdrenerénde. Dersom det er ønskelig kan de indre flater i ventilen være foret for å frembringe en hygienisk ventil, og dersom det er ønskelig kan hele ventilen, for noen bruksområder være fremstilt av plastmateriale. Valves of the described type can be used with any orientation and with a horizontal orientation of the valve closing chamber, the valve is completely self-draining. If desired, the inner surfaces of the valve can be lined to produce a hygienic valve, and if desired, the entire valve can, for some applications, be made of plastic material.

Det er også mulig, og i noen ventilutforminger foretrukket, å utelate endeflensen 16 i det elastiske, hule organ 17. I denne form av det hule organ er dettes ender festet til ventilhuset 10. It is also possible, and in some valve designs preferred, to omit the end flange 16 in the elastic, hollow member 17. In this form of the hollow member, its ends are attached to the valve housing 10.
