Description
Avstengningskran med føringsbøssinger for kulekiken. Shut-off valve with guide bushings for the ball valve.
Det er kjent avstengningskraner med Shut-off taps are also known
kuleformet kik uten føringstapper, som inne i kranhuset er sentrert ved hjelp av koaksialt med gjennomstrømmingsboringen innskrudde eller på annen måte festede føringsbøssinger, og som er avtettet ved hjelp av på begge sider anordnede koaksiale tetningsringer, idet disse på den side som vender fra kulekiken, står under trykk av såvel det strømmende medium som fjærkraft. spherical eye without guide pins, which is centered inside the faucet housing by means of guide bushings screwed in coaxially with the through-flow bore or fixed in some other way, and which is sealed by means of coaxial sealing rings arranged on both sides, as these on the side facing away from the ball eye under pressure from both the flowing medium and spring force.
Oppfinnelsen angår slike avstengningskraner, og har til hensikt å forbedre disse, slik at fremstilling og sammenbygging gjø-res billigere ved en enklere sentrering av kulekiken i kranhuset, samtidig som det sikres en god tetning også for relativt høye driftstrykk. The invention relates to such shut-off taps, and aims to improve them, so that manufacture and assembly are made cheaper by a simpler centering of the ball head in the tap housing, while at the same time ensuring a good seal even for relatively high operating pressures.
Denne hensikt oppnåes ifølge oppfinnelsen ved at den mot kulekikens overflate liggende, elastiske stempelring fortrinnsvis har trapesformet tverrsnitt, og at den på dens andre side liggende, f jærbelastede, so-lide trykkring har styring i en sylindrisk utdreining i føringsbøssingens indre vegg, hvilken utdreining samtidig tjener til av-støtting av trykkfjæren. This purpose is achieved according to the invention by the fact that the elastic piston ring lying against the surface of the ball bearing preferably has a trapezoidal cross-section, and that the spring-loaded, solid pressure ring lying on its other side is guided in a cylindrical twist in the inner wall of the guide bushing, which twist at the same time serves to support the compression spring.
Mellom den ringflate av føringsbøssin-gen som vender mot kulekiken, og kulekikens overflate kan det være anordnet i og for seg kjente glideringer av lagermetall eller kunststoff, f. eks. teflon. Disse tjener til å gi bedre styring av kulekiken og til å redusere friksjon, slitasje og korrosjon. Between the annular surface of the guide bushing that faces the ball bearing and the surface of the ball bearing there can be arranged in and of themselves sliding rings of bearing metal or plastic, e.g. teflon. These serve to provide better control of the ball bearing and to reduce friction, wear and corrosion.
På tegningene ivises et utførelseseksem-pel. An embodiment example is shown in the drawings.
Fig. 1 er et aksialt lengdesnitt gjennom avstengningskranen og Fig. 1 is an axial longitudinal section through the shut-off valve and
fig. 2 er et utsnitt av fig. 1 vist ved den strekprikkede sirkel hvorav sees stil-lingen av den på kulekikens overflate liggende glidering, hvilken også ligger an mot føringsbøssingens indre kantflate. fig. 2 is a section of fig. 1 shown by the dashed-dotted circle from which the position of the sliding ring lying on the surface of the ball bearing can be seen, which also rests against the inner edge surface of the guide bushing.
Avstengningsventilens hus er betegnet med 1. På begge sider av huset 1 er flenser 2 påsveiset eller festet på annen måte. I disse flenser 2 kan på begge sider innskrues føringsbøsser 3. Disse sentrerer med ende-partiene 5 kulekiken 4 i huset 1. Førings-bøssingene 3 har på innsiden uttagninger 6, som tjener som føring og opptagelse av stempeltetningsringene 7, trykkringene 8 og trykkfjærene 9. De sistnevnte ligger mellom trykkringenes 8 utside og ringflaten 6' for uttagningen 6 i føringsbøssingen. Trykkringens 8 og tetningsringens 7 indre diameter er lik diameteren for gjennom - løpsboringen 10 i kiken 4. Føringsbøssingen 3 er ved tetningsringer 11 avtettet mot huset 1. The shut-off valve housing is denoted by 1. On both sides of the housing 1, flanges 2 are welded on or fixed in some other way. Guide bushings 3 can be screwed into these flanges 2 on both sides. These, with their end parts 5, center the ball bearing 4 in the housing 1. The guide bushings 3 have recesses 6 on the inside, which serve as a guide and receptacle for the piston sealing rings 7, pressure rings 8 and pressure springs 9 The latter are located between the outside of the pressure rings 8 and the ring surface 6' for the recess 6 in the guide bushing. The inner diameter of the pressure ring 8 and the sealing ring 7 is equal to the diameter of the through-bore 10 in the eye 4. The guide bushing 3 is sealed against the housing 1 by sealing rings 11.
Den i en utformet uttagning i kulekiken 4 inngripende kranspindel 12, har styring i husets parti 13 ved en lagerbøssing 18, som ved bolter 19 holdes på plass i den stilling som er vist i fig. 1. I en boring i delen 13 av kranhuset er det en anslagsstift 14, som tjener til begrensning av kranens åpnings- og lukkestilling. Såvel sperre-skiven 15 som betjeningsarmen 16 for kra-nen er lagret på spindelens 12 firkantede parti 12'. Betjeningsarmen 16 er festet ved hjelp av skruen 17. The crane spindle 12, which engages in a designed recess in the ball cage 4, is controlled in the part of the housing 13 by a bearing bushing 18, which is held in place by bolts 19 in the position shown in fig. 1. In a bore in part 13 of the crane housing, there is a stop pin 14, which serves to limit the opening and closing position of the crane. Both the locking disk 15 and the operating arm 16 for the crane are stored on the square part 12' of the spindle 12. The operating arm 16 is fixed by means of the screw 17.
I fig. 2 er det anordnet en glidering 5' som ligger an mot kulekikens 4 overflate og er av lagermetall eller kunststoff. Ved anvendelse av en slik glidering, som — som In fig. 2, a sliding ring 5' is arranged which rests against the surface of the ball bearing 4 and is made of bearing metal or plastic.
