Medbringarskivan 8 Or forsedd med ett hal 17, som icke Or helt runt utan som Or utvidgat nagot i medbringarskiyans 8 radialriktning. I halet 17 Or en tapp 18' inford, vilken tapp Or anordnad pa ett utsprang 19 ph en plan ring 20, som Or utbildad med en innerganga. Bingen 20 utgor den ena delen av ett av tva delar sammansatt aystangningsorgan, mars andra del 20a Or forsedd med en tapp 21, som Or utbildad med en ytterganga. Tappen 21 Or inskruvad i ringen 20. Tappen 21 Or pa sin ena andyta utbildad med en fordjupning 22 och Or yid sin andra andyta forsedd med en sexkantig platta 23, vilken Or gjord i ett stycke med tappen. Ventilhusdelen 2 Or pa insidan utbildad med tva parallella 2— f92575 — styrningar 24 for tva motliggande sidor pa den sexkantiga plattan 23. Platt= 23 ligger I det visade avstangningslaget an mot ett ringformat sate 25 och tillsluter en genomstromningsoppning 26 i ventilhusdelen 2. The carrier disc 8 Or is provided with a hall 17, which is not completely round but which has expanded somewhat in the radial direction of the carrier disc 8. In the tail 17 there is a pin 18 'inserted, which pin Or arranged on a projection 19 ph a flat ring 20, which Or is formed with an inner passage. The bin 20 forms one part of one of the two-part composite aystangling means, March the second part 20a Or provided with a pin 21, which Or is formed with an outer passage. The pin 21 is screwed into the ring 20. The pin 21 is formed on one end face with a recess 22 and is provided on its other end face with a hexagonal plate 23, which is made in one piece with the pin. Valve housing part 2 Or on the inside formed with two parallel 2— f92575 - guides 24 for two opposite sides of the hexagonal plate 23. Plate = 23 lies in the shown cut-off layer against an annular seat 25 and closes a flow-through opening 26 in the valve housing part 2.

Ringen 20 ligger i detta lage an mot ett ring- format sate 27 i ventilhusdelen 1 och tillsluter tillsammans med tapper' 21 en genomstromningsoppning 28 i denna ventilhusdel; ventilhusdelen 1 är vidare utbildad med tva parallella styrningar 29 for ringen 20. The ring 20 abuts in this position against an annular sate 27 in the valve housing part 1 and together with pins 21 closes a flow opening 28 in this valve housing part; the valve housing part 1 is further formed with two parallel guides 29 for the ring 20.

I fig. 1 antydes med punktstreckade linjer, hurusom avstangningsventilen ar anbragt mellan flansar 30 och 31 pa tvenne ror (se aven fig. 4). Forutom tvd bultar 32, som tjana till att sammanhalla flansarna vid varand- ra, aro andra bultar genomforda genom hal i dessa flansar och genom halen 3' och 4' i ventilhusdelarna 1 och 2. Packningar 33 aro an- erdnade mellan flansarna och ventilhuset. Sedan hultarna avlagsnats, kan man dra ut avstangningsventilen mellan flansarna 30 och .31; anslutning och borttagning av ventilen är salunda ytterst enkel. Fig. 1 indicates with dotted lines how the shut-off valve is arranged between flanges 30 and 31 on two pipes (see also Fig. 4). In addition to two bolts 32, which serve to hold the flanges together at each other, other bolts are passed through halts in these flanges and through the tails 3 'and 4' in the valve housing parts 1 and 2. Gaskets 33 are arranged between the flanges and the valve housing. After the bolts have been removed, the shut-off valve can be pulled out between the flanges 30 and .31; connection and removal of the valve is thus extremely simple.

Far forklaring av den beskrivna avstangningsventilens arbetssatt antages forst, att ha- let 17 i medbringarskivan 8 är exakt runt. I detta fall skulle tappen 18 vid vridning av manoverarmen 1& rora sig exakt utefter den cir- kel 34, som i fig. 3 ar utmarkt med en punkt- streckad linje, och bibringa ringen 20 och ,darmed aven plattan 23 en fram- och Ater- ga.ende rorelse. Medbringarskivan 8 utgor i sjalva verket blott en speciell form av en vevslang. Explaining the operation of the shut-off valve described first, it is first assumed that the hole 17 in the drive plate 8 is exactly round. In this case, when the control arm 1 is rotated, the pin 18 would move exactly along the circle 34, which in Fig. 3 is marked with a dotted line, and impart to the ring 20 and, thereby also the plate 23, a forward and backward - ga.ende rorelse. The carrier disc 8 is in fact only a special shape of a crank hose.

Da manoverarmen 10 i detta fall vid stangd -ventil befinner sig i det i fig. 4 antydda stang- ningsldget 10' och vrides i den riktning, som anges av den med »tippen>.) betecknade pilen. Tor sig tappen 18 utefter cirkeln 34 i den rikt- ning, som anges av den i fig. 3 angivna pilen. Vid det i ritningen visade nedre dodlaget ar den genom vridningen astadkomna forskjutningen av ringen 20 till en borjan blott ringa; daremot vrides till en bOrjan denna ring avsevart medurs enligt fig. 3, varigenom den pa- skruvas langre upp pa tappen 21, vilken tapp pa grund av plattans 23 styrning fran styrytorna 24 ej kan vrida sig tillsammans med ringen 20. Darigenom minskar till en borjan aTstandet mellan de ytor pa plattan 23 och ringen 20, som frail borjan under tatning pressas mot satena 25 resp. 27, dvs. avstangningsorganets 20-20a verksamma tjocklek minskar, sa att darefter, vid ytterligare vridning av manoverarmen 10, avstangningsorganet utan motsta'nd lanas styrningarna 24 resp. 29 kan forskjutas fran sitt stangningslage. Since the control arm 10 in this case with the valve closed is located in the closing member 10 'indicated in Fig. 4 and is rotated in the direction indicated by the arrow denoted by the "tip". Rotate the pin 18 along the circle 34 in the direction indicated by the arrow indicated in Fig. 3. In the lower death layer shown in the drawing, the displacement of the ring 20 brought about by the rotation to a beginning is only slight; on the other hand, this ring is turned clockwise counterclockwise according to Fig. 3, whereby it is screwed further up on the pin 21, which pin due to the control of the plate 23 from the guide surfaces 24 cannot turn together with the ring 20. Thereby decreasing to a beginning The condition between the surfaces of the plate 23 and the ring 20, which from the beginning during sealing is pressed against the seats 25 and 25, respectively. 27, i.e. the effective thickness of the shut-off member 20-20a decreases, so that then, upon further rotation of the operating arm 10, the shut-off member without resistance is guided by the guides 24 and 24, respectively. 29 can be displaced from its rod bearing.

Efter en vridning av manoverarmen 10, som ar stOrre an 90°, bOrjar ringen 20 att vrida sig moturs, sa att den skruvas tillbaka pa tap-pen 21, varigenom avstangningsorganets 2020a verksamma tjocklek ater tilltager. Efter 180° vridning, dvs. i vevslangens Owe dodlage, dr avstangningsorganet 20-20a fastklamt mellan medbringarskivan 8 och ventilhusdelen 2, varigenom det sakras i sitt Oppna lage. Vid stangning av ventilen sker det beskrivna forloppet i omvand ordning: avstangningsorganet losgOres fran sitt fastklamda lage, forskjutes till stangningslaget och pressas dir Ater mot satena 25 och 27. After a rotation of the control arm 10, which is greater than 90 °, the ring 20 begins to turn counterclockwise, so that it is screwed back onto the pin 21, whereby the effective thickness of the shut-off member 2020a increases again. After 180 ° rotation, ie. in the Owe dead layer of the crank hose, the shut-off member 20-20a is clamped between the carrier plate 8 and the valve housing part 2, whereby it is secured in its open layer. When closing the valve, the described process takes place in the reverse order: the shut-off means is released from its clamped bearing, displaced to the closing layer and pressed dir Ater against the seats 25 and 27.

Da tappens 18 spel i medbringarskivans radialriktning i halet 17 Or stort, rOr sig tappen 18 i sjalva verket icke exakt utefter cirkeln 34. Vid vridning av medbringarskivan fran dodlagena sker darvid till en borjan blott en vridning av ringen. 29, utan att densamma forskjutes, sâ att den darpa foljande forskjutningen kan ske under liten friktion, emedan avstanguingsorganets 20-20a verksamma tjocklek redan liar minskats i tillrfieklig utstrackning, da forskjutningen tager sin bar-j an. Since the play of the pin 18 in the radial direction of the carrier disc in the tail 17 is large, the pin 18 is in fact not exactly along the circle 34. When the carrier plate is rotated from the dead layers, only a rotation of the ring takes place at the beginning. 29, without it being displaced, so that the subsequent displacement can take place under low friction, since the effective thickness of the resting member 20-20a has already been reduced to a sufficient extent, as the displacement takes its toll.

Den i fig. 5 och 6 visade avstangningsventilen Or avsedd for stOrre dimensioner och/ eller hogre tryck. De rorliga delarna Oro utbildade ph exakt samma satt som i en ventil enligt fig. 1.-4, men ventilhusdelarna 35 och 36 Oro forsedda med ett st8rre antal hal 37, 38 resp. 37', 38' for ett motsvarande stOrre antal bultar 39 resp. 40 for sammanhallning av ventilhusdelarna. Det finns fern bultar 39, vilka endast genomfOras genom de som flansar utbildade kanterna pa ventilhusdelarna 35 och 36 (i stallet for tre, som i det forsta utf0- ringsexemplet), och tre bultar 40, som darjamte genomforas Oven genom rorflansarna 41 och 42 (i stallet for bra, som i det forsta utforingsexemplet) . The shut-off valve Or shown in Figs. 5 and 6 is intended for larger dimensions and / or higher pressures. The movable parts Oro formed ph exactly the same way as in a valve according to Figs. 1.-4, but the valve housing parts 35 and 36 Oro are provided with a larger number of slides 37, 38 and 37 ', 38' for a correspondingly larger number of bolts 39 resp. 40 for assembling the valve housing parts. There are four bolts 39, which are only passed through the flanged edges of the valve housing parts 35 and 36 (instead of three, as in the first embodiment), and three bolts 40, which are also passed through the rudder flanges 41 and 42 ( in the stable for good, as in the first lining example).

De genom de hada halen 41a i flansen 41 och genom de motsvarande halen i flansen 42 genomforda bultarna genomforas icke genom ventilhusdelarna 35 och 36. The bolts penetrated through the had tail 41a in the flange 41 and through the corresponding tails in the flange 42 are not passed through the valve housing parts 35 and 36.

Till ventilen hor Oven en krampa 43, sammansatt av tva. tvarsldar 44. Var sla bar ett kraftigt liv och Or i andarna forsedd med Oglor 45. Genom de tva paren motliggande oglor 45 Oro icke utritade bultar genomforda, vilka Oro forsedda med motsvarande muttrar, varigenom tvarslaarna 44 fast sammanhallas. 130 sidan av var slits liv aro tre tappar 46 fastsvetsade, vilkas korta utskjutande delar 47 passa in i tre hal i rorflamarna 41 resp. 42. Vid fastdragning av krampan 43 forstarkes i hog grad forbandet mellan de bada rorflansarna 41 och 42, liksom fiSrbandet mellan ventilhusdelarna 35 och 36. To the valve belongs Oven a cramp 43, composed of two. crossbars 44. Each slab bore a strong life and Or in the spirits fitted with Oglor 45. Through the two pairs of opposite oglors 45 Oro not drawn bolts through, which Oro provided with corresponding nuts, whereby the crossbars 44 are firmly held together. 130 side of each slot life are three pins 46 welded, the short projecting parts 47 of which fit into three halls in the rudder flames 41 resp. 42. When tightening the cramp 43, the connection between the two rudder flanges 41 and 42, as well as the connection between the valve housing parts 35 and 36, is greatly strengthened.

Fran ventilhusdelens 35 lagerhylsa 6 utgar en bagformad forstarkningsfjader 48, mot vii-ken flansen 41 ligger an, och dessutom en forstarkningsfjader 49. Ventilhusdelen 36 Or forsedd med en bagforma:d fOrstarkningsfjader 50, mot silken flansen 42 ligger an, och dessutom med tva vinkelratt mot varandra forlopande forstarkningsfjadrar 51 och 52. From the bearing sleeve 6 of the valve housing part 35 a rear-shaped reinforcing spring 48 projects, against which the flange 41 abuts, and in addition a reinforcing spring 49. The valve housing part 36 Or is provided with a rear-shaped reinforcing spring 50, against the silk flange 42 abuts, opposing reinforcing springs 51 and 52.

Den beskrivna avstangningsventilen har den — --3 fordelen, att den tillsluter mycket tatt. I forhallande till kanda ventiler av motsvarande slag, vid vilka — med andra medel — en pressning av ventilkroppen mot satet astadkomrnes i stangningslaget, uppvisar MmHg- gande ventil en enklare uppbyggnad samt av- sevart mycket mindre yolym hch vikt. Viktminskriingen i forh011ande till i praktiken ofta anvanda ventiler uppgar till over 50 %. De hada flata ventilhusdelarna 1, 2 resp. 35, 36 kunna gjutas i mycket enkla formar och kunna mycket latt bearbeta.s. The described shut-off valve has the - --3 advantage that it closes a lot. In relation to known valves of a corresponding type, in which - by other means - a pressing of the valve body against the seat is effected in the closing stroke, the MmHg-going valve has a simpler construction and has a considerably smaller volume and weight. The weight loss in relation to valves often used in practice often amounts to more than 50%. They had flat valve housing parts 1, 2 resp. 35, 36 can be cast in very simple molds and can be processed very easily.s.

Genom att plattan 23 hair formen av en regelbunden sexhorning är det majligt att anbringa den i olika lagen, vinkelforskjutna 600 i forhallande till varandra. Detta medger en installning av det tryck, som av avstangningsorganet 20, 20a i stangningslaget skall utovas mot satena 25, 27. Plattan 23 skulle aven kunna ha formen av en regelbunden fyrhorning, attahorning etc., dvs. formen av en regelbunden manghorning med ett jamnt antal horn. For samma andamal kan man anordna flera hal 17 i medbringarskivan 8, foretradesvis ytterligare ett hal, forskjutet 1800 I fOrhallande till halet 17 och med ett nagot annat radialspel, varvid tappen 18 infores i det ena eller det andra av dessa hal. By the plate 23 hair the shape of a regular hexagon, it is possible to apply it in different layers, angularly offset 600 in relation to each other. This allows an installation of the pressure which is to be exerted by the shut-off means 20, 20a in the locking layer against the sates 25, 27. The plate 23 could also have the shape of a regular quadrilateral, attahorn, etc., i.e. the shape of a regular polygon with an even number of horns. For the same purpose, several halls 17 can be arranged in the carrier disc 8, preferably another hall, offset 1800 I in relation to the hall 17 and with a slightly different radial play, the pin 18 being inserted into one or the other of these halls.

Det är naturligtvis icke nodvandigt, att bulten 7 och medbringarskivan 8 aro gjorda i ett stycke; delarna 7 och 8 kunna vara fast forbundna med varandra pa vilket som heist satt. Likasa ar det endast nodvandigt, att tappen 21 och plattan 23 aro fast forbundna med varandra, men icke att de aro gjorda i ett stycke, ehuru (let sistnamnda utforandet av sakerhetsskal dr att foredraga. Vidare bor pa.pekas, att vevslangen 8 pa vilket som helst satt kan vara kinematiskt forbunden med manoverarmen 10 och icke blott ph det i ritningarna visade, mycket enkla sattet. It is of course not necessary that the bolt 7 and the carrier disc 8 are made in one piece; the parts 7 and 8 can be firmly connected to each other in whatever way. Likewise, it is only necessary that the pin 21 and the plate 23 are fixedly connected to each other, but not that they are made in one piece, although the latter design of safety shells is preferred there. any set can be kinematically connected to the control arm 10 and not only ph the very simple set shown in the drawings.

Tappen 18 skulle i stallet fOr pa ringen 20 kunna vara anordnad pa medbringarskivan 8, varyid halet 17 i stallet for i medbringarskivan 8 skulle vara anordnat i ringen 20. Ringen 20 skulk kunna vara styrd i ventilhusdelen 2 och plattan 23 i ventilhusdelen 1 utan andring av medbringarskivans 8 lage. The pin 18 could instead of the ring 20 be arranged on the carrier plate 8, the tail 17 instead of the carrier plate 8 could be arranged in the ring 20. The ring 20 could be guided in the valve housing part 2 and the plate 23 in the valve housing part 1 without changing the carrier's 8 layer.

I stallet for att anordna en krampa skulle man kunna svetsa fast tva forstarkningsfjadrar, som motsvara tvarslaarna 44, pa rorflansarna 41 och 42 och vid andarna forbinda dessa forstarkningsfjadrar med varandra me-deist bultar. Instead of arranging a cramp, one could weld two reinforcing springs, corresponding to the transverse shafts 44, on the rudder flanges 41 and 42 and connect these reinforcing springs to each other by means of bolts.

FOr den handelse avstangningsventilen är aysedd for mycket tjockflytande vatskor, t. ex. raolja eller tjara, kan man fOrse var ventilhusdel med ytterligare en del, vilken, t. ex. tillsammans med ventilhusdelarna 1 resp. 2, bildar ett halrum, van i anga eller varmvatten kan cirkuleras eller van i en elektrisk uppvarmningsanordning kan anbringas. Dessa ventilhusdelar kunna eventuent vara fhstade vid ventilhusdelarna 1 och 2 med samma bul tar, som tjana till att sammanhalla ventilhusdelarna 1 och 2. For the trade shut-off valve is provided for very viscous water shoes, e.g. crude oil or tar, one can fOrse each valve housing part with another part, which, e.g. together with the valve housing parts 1 resp. 2, forms a cavity, van in steam or hot water can be circulated or van in an electric heating device can be applied. These valve housing parts may optionally be attached to the valve housing parts 1 and 2 with the same bulge, which serve to hold the valve housing parts 1 and 2 together.

I stallet for att anordna en ganga, som for-binder delarna 20 och 20a med varandra, skulle man Oven kunna farse dessa delar med i en ring anordnade utsprang eller kammar med i tangentialriktningen lutande ytor fOr att uppna samma verkan. Instead of arranging a thread which connects the parts 20 and 20a to each other, it would also be possible to stuff these parts with projections arranged in a ring or combs with surfaces inclined in the tangential direction in order to achieve the same effect.

Den i fig. 7 visade avstangningsventilen innefattar ater tva flata ventilhusdelar 1 och 2, vilka var och en vid sina som flansar utbildade kanter aro forsedda med hal 3 resp. 4, genom vilka icke utritade bultar genomforas, for att fast forbinda de bada ventilhusdelarna med varandra. Ventilhusdelen 1 Or utbildad med en lagerhylsa 6, van i en utskjutande, med ansats forsedd bult 7 Or lagrad. Bulten 7 är gjord i ett stycke med en medbringarskiva 8, som befinner sig i ventilhuset, och en mani5verarm 10 Or fastad darpa. Medbringarskivan 8 Or forsedd med ett hal 17, som Or nagot utvidgat i skivans radialriktning. I Met Or en tapp 18 inford, vilken tapp Or anbragt pa ett utsprang 19 pa ett tillslutningselement 60. Detta element 60 Or i detta fall ej utbildat som en ring som vid de i fig. 1-6, visade utforingsformerna, utan som en skiva, vilken Or fOrsedd med en at hada sidor utvidgad kant 61. Ena sidan av denna kant 61 ligger vid det i ritningen visade avstangningslaget an mot en bronsring 62, som Or anordnad i ett mot ring-en svarande urtag i ventilhusdelen 1 vid dess genomstrOmningsoppning 28. The shut-off valve shown in Fig. 7 again comprises two flat valve housing parts 1 and 2, each of which at its edges formed as flanges are provided with halves 3 and 3, respectively. 4, through which undrawn bolts are passed, to firmly connect the two valve housing parts to each other. Valve housing part 1 Or formed with a bearing sleeve 6, used in a projecting, bolted bolt 7 Or bearing. The bolt 7 is made in one piece with a drive disc 8, which is located in the valve housing, and a control arm 10 Or fixed darpa. The carrier disc 8 Or provided with a slide 17, which Or slightly extended in the radial direction of the disc. In Met Or a pin 18 is inserted, which pin Or is arranged on a projection 19 on a closing element 60. This element 60 In this case Or is not formed as a ring as in the embodiments shown in Figs. 1-6, but as a disc One side of this edge 61 abuts the bronze ring 62 shown in the drawing, which is arranged in a recess corresponding to the ring in the valve housing part 1 at its flow opening 28. .

One side of the edge 67 abuts a bronze ring 68, which Or is arranged in a recess corresponding to the ring in the valve housing part 2 at its flow-through opening 26. In the middle and ph of the disc 66 there is arranged a cam curve 69, which Or is provided with a central bore 70, used in the pin for insertion.

For tydlighets skull Or skivan 66 avbildad perspektiviskt i fig. 8. Av denna figur framgar, att skivans 66 omkrets icke Or rund utan attakantig. Skivan 66 styres Oven i detta fall av tva parallella styrningar 24 i ventilhuset 2 och kan icke yrida sig, da den fOrskjutes, emedan tva motliggande sidor ay attahorningen ligga an mot dessa styrytor.

This figure shows that the circumference of the disc 66 is not Or round but angular. The disc 66 is also controlled in this case by two parallel guides 24 in the valve housing 2 and cannot rotate as it is displaced, since two opposite sides of the attachment abut against these guide surfaces. The disc 60 dar- - - against Or round and can be displaced under control Iran tvd parallel guides 29 in the valve housing part 1.

De hada kamkurvorna 64 och 69 aro lampligen omgivna av en valvd tatningsmanschett 72 (se fig. 7). Tatningsmanschetten 72 kan vara gjord av brans eller gummi; den är utbildad med en valvd, fjadrande mittdel 73 och med tva forstyvande andringar 74. Ringarna 74 tryckas under inverkan frail den fjadrande mittdelen 73 utat, alltsa einot skivorna 60 och 66, varigenom de, oberoende av avstandet mellan dessa skivor, under tatning avskilja kamkurvorna fran den vatska, som finnes i ventilhuset 1, 2. The cam curves 64 and 69 are suitably surrounded by a curved sealing sleeve 72 (see Fig. 7). The sealing sleeve 72 may be made of bran or rubber; it is formed with a curved, resilient center portion 73 and with two stiffening changes 74. The rings 74 are pressed under the action of the resilient center portion 73 outwardly, i.e. one of the discs 60 and 66, whereby they, independently of the distance between these discs, tightly separate the cam curves from the fluid contained in the valve body 1, 2.

Den senast beskrivna avstangningsventilen fungerar pa foljande salt: vid det i fig. 7 visade avstangningslaget befinna sig ansatserna pa kamkurvorna 64 och 60 pa ett visst vinkelavstând frail varandra. Skivorna 60 och 66 befinna sig i detta lage pa det storsta avstandet fran varandra, varvid genom kamkurvorna skivornas kanter 61 resp. 67 pressas mot de saten, som ringarna 62 resp. 68 utgora. Skivorna 60 och 66 aro sã dimensionerade, att de i delta lage under fjadring giva efter, 1. ex. omkring 0,2-1 mm da ventilen Or ny. DOrvid skola ej de utvidgade kanterna 61 resp. 67 deformeras pa grund av skivornas 60 resp. 66 fjadring, varigenom de bibehalla sina korrekta lagen parallellt med satesringarna 62 resp. 63. Skivornas fjadring a.ventyrar salunda icke den goda tatningen. Dá efter en tids anvandning ringarna 62 och 68 saval som tatningskanterna 61 och 67 ha notts nagot mot varandra, blir skivornas 60 och 66 fjadring i stangningslaget nagot mindre. Kanterna 61 och 67 pressas alltfort under fjadertryek mot satesringarna 62 och 68 ehuru det av kamkurvorna 64 och 69 hestamda avstandet mellan skivorna 60 och 66 fir detsamma, som da ventilen var fly — am man bortser frail den ringa avnotning fran kamkurvorna sjalva, som likaledes skulle leda till att ventilen bleve otat, om skivorna 60 oeh 66 voro styva. De avstangningselement, som i den i fig. 1-6 visade avstangningsventilen motsvara skivorna 60 och 66, aro i jamfiirelse med dessa skivor ytterst styva. For erhfillande av god fjadring hos skivorna ãr det lampligt att icke gOra kamkurvornas 64 och 69 diametrar star-re On 40 % av skivornas diametrar. The most recently described shut-off valve operates on the following salt: in the shut-off layer shown in Fig. 7, the shoulders of the cam curves 64 and 60 are at a certain angular distance from each other. The discs 60 and 66 are in this position at the greatest distance from each other, whereby through the cam curves the edges 61 and 61 of the discs, respectively. 67 is pressed against the sets, which the rings 62 resp. 68 utgora. The discs 60 and 66 are so dimensioned that in yield they give way during suspension, 1. ex. about 0.2-1 mm when the valve Or new. In addition, the widened edges 61 resp. 67 are deformed due to the discs 60 and 60, respectively. 66 suspension, whereby they maintain their correct laws parallel to the sates rings 62 resp. 63. The suspension of the discs thus does not endanger the good sealing. Then, after a period of use, the rings 62 and 68, as the sealing edges 61 and 67 have been worn slightly against each other, the suspension of the discs 60 and 66 in the rod layer becomes somewhat smaller. The edges 61 and 67 are constantly pressed under spring pressure against the sates rings 62 and 68, although the distance between the discs 60 and 66 of the cam curves 64 and 69 is the same as when the valve was flown - except for the slight wear from the cam curves themselves, which would likewise cause the valve to become untouched if the discs 60 and 66 were rigid. The shut-off elements, which in the shut-off valve shown in Figs. 1-6 correspond to the discs 60 and 66, are in comparison with these discs extremely rigid. In order to obtain good suspension of the discs, it is appropriate not to make the diameters of the cam curves 64 and 69 larger On 40% of the diameters of the discs.

Vid oppning av ventilen omvrides manoverarmen 10, varvid, via den vevslang, som medbringarskivan 8 utgor, tappen 18, som Or in-ford i halet 17 i skivan 8, och utspran.get 19 draga den runda skivan 60 uppat i styrningarna 29; darvid vrides skivan 60. Denna skiva for, via tappen 63, med sig skivan 66 upp- styrningarna 24. DO skivan 66 darvid icke kan vrida sig, vridas skivorna 60 och 66 relativt varandra, varvid vridningen sker i sadan riktning, att ansatserna i kamkurvorna 64 resp. 69 narma sig varandra, varav foljer, att skivorna 60 och 66 narma sig varandra och att dessa skivor losgoras frail satesringarna 62 och 68. Det avstangningsorgan, som skivorna 60 och 66 hilda, drages uppat, tills genomstromningsoppningarna 26 och 28 fritt Oro forbundna med varandra. When the valve is opened, the control arm 10 is rotated, whereby, via the crank hose constituting the carrier disc 8, the pin 18, which is inserted into the tail 17 in the disc 8, and the projection 19 pull the round disc 60 upwards in the guides 29; the disc 60 is rotated. This disc carries, via the pin 63, with it the disc 66 the guides 24. DO the disc 66 thereby cannot rotate, the discs 60 and 66 are rotated relative to each other, the rotation taking place in such a direction that the shoulders in the cam curves 64 resp. 69 approach each other, from which it follows that the discs 60 and 66 approach each other and that these discs are released from the sates rings 62 and 68. The support member, which the discs 60 and 66 hold, is pulled upwards, until the flow openings 26 and 28 are freely connected to each other. .

Efter 900 vridning av manoverarmen 10 ha skivorna 60 och 66 det minsta aystandet frail varandra.
