Ventil. Valve.

Denne oppfinnelse vedrører en ventil hvis legeme bæres This invention relates to a valve whose body is carried

av en spindel.som er forskyvbar i lengderetningen ved hjelp av en kamdrivinnretning og som er pådratt av en fjær som virker i ventilens stengeretning, cg hvilken kamdrivinnretning i sin til ventilens stengte tilstand svarende stilling har klaring mellom kamorganet of a spindle which is displaceable in the longitudinal direction by means of a cam drive device and which is attracted by a spring which acts in the closing direction of the valve, cg which cam drive device in its position corresponding to the valve's closed state has clearance between the cam member

og det drivorgan som er i anlegg med kammen. and the drive member which is in contact with the cam.

Ventillegemet i en ventil av den nettopp nevnte type er vanligvis utstyrt med en tetning som er innrettet til å komme i anlegg med et ventilsete. Denne tetning slites ned etter hvert med det resultat at anlegget mellom tetningen og setet etter hvert blir mindre bra og stengevirkningen mindre pålitelig. The valve body in a valve of the type just mentioned is usually equipped with a seal which is arranged to come into contact with a valve seat. This seal gradually wears down with the result that the system between the seal and the seat gradually becomes less good and the closing effect less reliable.

Hensikten med denne oppfinnelse er å forhindre at ventilen brukes selv om tetningen er nedslitt altfor meget. Denne hen-sikt kar man oppnådd ved at kamflatens endeparti som er tilordnet ventilens stengestilling, har en fordypning som drivorganet ved stengt ventil smetter inn i og sperrer drivinnretningen når tykkelsen av tetningen mellom ventilsetet <p>g ventillegemet underskrider en forutbestemt toleransegrense. Når tetningen er nedslitt, blokkeres drivinnretningen og ventilen lar seg ikke åpne. Tetningen må The purpose of this invention is to prevent the valve from being used even if the seal is excessively worn. This purpose can be achieved by the end part of the cam surface, which is assigned to the valve's closed position, having a recess that the drive member slips into when the valve is closed and blocks the drive device when the thickness of the seal between the valve seat <p>g the valve body falls below a predetermined tolerance limit. When the seal is worn, the drive device is blocked and the valve cannot be opened. The seal must

da skiftes ut. Man vil også få et forhåndsvarsel om at tetningen begynner å bli nedslitt, fordi det etter hvert blir vanskeligere å få åpnet ventilen på grunn av smettevirkningen. Dette er en vesent-lig fordel ved en ventil fordi man da skifter ut ventilen før bety-delige ulemper begynner å melde seg slik at man unngår driftsfor-styrrelser, væsketap og eventuelt også skader på grunn av lekkasjer0. then replaced. You will also receive an advance warning that the seal is beginning to wear down, because it will gradually become more difficult to open the valve due to the contagion effect. This is a significant advantage of a valve because you then replace the valve before significant disadvantages begin to appear, so that you avoid operational disturbances, loss of fluid and possibly also damage due to leaks0.

Oppfinnelsen skal forklares nærmere ved hjelp av et ek-sempel under henvisning til tegningene, hvor: Fig. 1 viser et lengdesnitt gjennom ventilen, og fig. 2, 3 og 4 hhv. et lengdesnitt, et grunnriss og en utfolding av ventilens kamorgan. The invention shall be explained in more detail by means of an example with reference to the drawings, where: Fig. 1 shows a longitudinal section through the valve, and fig. 2, 3 and 4 respectively. a longitudinal section, a ground plan and an unfolding of the valve cam.

Den på tegningene viste ventil har et ventilhus 1 med stusser 2 og 3 for tilkobling av ledninger. I huset er det anordnet et ventilsete 4. Et ventillegeme 5 er festet på en spindel 6, hvis øvre del 7 har kvadratisk tverrsnitt og er forskyvbar i lengderetningen langs ventilsetets 4 akse i en føring 9 med tilsvarende til-passet åpning 8. En skruefjær 10 er anordnet koaksialt med spindelen 6 og virker i stengeretningen på ventillegemet 5. The valve shown in the drawings has a valve housing 1 with connectors 2 and 3 for connecting lines. A valve seat 4 is arranged in the housing. A valve body 5 is attached to a spindle 6, the upper part 7 of which has a square cross-section and is displaceable in the longitudinal direction along the axis of the valve seat 4 in a guide 9 with a correspondingly adapted opening 8. A coil spring 10 is arranged coaxially with the spindle 6 and acts in the closing direction on the valve body 5.

For omdannelse av ventilhåndtakets 11 dreiebevegelse til spindelens 6 og ventillegemets 5 rettlinjede bevegelse er det i ventilen anordnet en kamdrivinnretning omfattende et hult sylindrisk kamorgan 12 som samvirker med et drivorgan i form av en krysspinne 13 som går gjennom spindelen. Kamorganet 12 er koaksialt med spindelen 6 og er lagret på en ansats 14 på føringsstykket 9 og har ved sin bort fra ventillegemet 5 vendende ende to diametralt motsatt be-liggende i. omkretsretningen forløpende kamflater 15 og 16. Håndtaket 11 er fast forbundet med kamorganet 12, idet en indre fortanning 17 i håndtaket griper i en ytre fortanning 18 på kamorganet 12. Krysspinnen 13 forløper diametralt over kamorganet 12 og pinnens en-der ligger på hver sin kamflate 15 hhv. 16 når ventilen ikke er stengt fordi fjæren 10 presser pinnen mot kamflåtene. Kamorganet To convert the turning movement of the valve handle 11 into the rectilinear movement of the spindle 6 and the valve body 5, a cam drive device is arranged in the valve comprising a hollow cylindrical cam member 12 which cooperates with a drive member in the form of a cross pin 13 which passes through the spindle. The cam member 12 is coaxial with the spindle 6 and is mounted on a shoulder 14 on the guide piece 9 and has at its end facing away from the valve body 5 two diametrically opposed cam surfaces 15 and 16 running in the circumferential direction. The handle 11 is firmly connected to the cam member 12 , with an inner serration 17 in the handle engaging an outer serration 18 on the cam member 12. The cross pin 13 runs diametrically over the cam member 12 and the ends of the pin lie on each cam surface 15 or 16 when the valve is not closed because the spring 10 presses the pin against the cam floats. The chamber organ

12 kan dreies i ventilens stengeretning til en stilling hvor ventillegemet 5 kommer til anlegg med ventilsetet 4 samtidig som kamflate- 12 can be turned in the closing direction of the valve to a position where the valve body 5 comes into contact with the valve seat 4 at the same time that the cam surface

ne 15 og 16 fjerner seg fra pinnen 13. Man får da en klaring slik at fjæren 10 kan presse ventillegemet 5 mot ventilsetet 4. Kryss-pinnens stilling med stengt ventil er vist ved 13' på fig. 4. pins 15 and 16 are removed from the pin 13. A clearance is then obtained so that the spring 10 can press the valve body 5 against the valve seat 4. The position of the cross pin with the valve closed is shown at 13' in fig. 4.

Kamflatenes 15 og 16 endeparti som er tilordnet venti- The end parts of the cam surfaces 15 and 16 which are assigned to venti-

lens åpne stilling, har en fordypning 19 som pinnen 13 smetter inn i når ventilen er åpen slik at ventilen fastholdes i denne stilling. Kamflatenes 15 og 16 endeparti som er tilordnet ventilens stengte stilling, har en fordypning 21 som er anordnet og utformet slik at pinnen 13 bare kan smette inn i denne fordypning ved stengt ventil når tykkelsen av ventillegemets 5 tetning 20 underskrider en forutbestemt verdi. Denne fordypning er utført slik at ventilen under pinnens 13 innsmetning i denne blokkeres i stengestillingen (pin- len's open position, has a recess 19 into which the pin 13 slips when the valve is open so that the valve is retained in this position. The end part of the cam surfaces 15 and 16, which is assigned to the closed position of the valve, has a recess 21 which is arranged and designed so that the pin 13 can only slip into this recess when the valve is closed when the thickness of the seal 20 of the valve body 5 falls below a predetermined value. This depression is made so that the valve is blocked in the closed position when the pin 13 is inserted into it (pin-

nens stilling 13" på fig. 4). Derved hindres at ventilen arbeider med en utillatelig sterkt nedslitt tetning 20 og medvirker til at tetningen kan skiftes ut i rett tid. position 13" on fig. 4). This prevents the valve from working with an impermissibly severely worn seal 20 and helps ensure that the seal can be replaced at the right time.

Kamflatenes 15, 16 stigning kan under hensyntagen til fjærens 10 kraft være dimensjonert slik at ventilen vil stenges au-tomatisk ved utsmetning av pinnen 13 fra fordypningen 19. Uten fordypningen 19 vil ventilen være en selvlukkende ventil. The pitch of the cam surfaces 15, 16 can, taking into account the force of the spring 10, be dimensioned so that the valve will close automatically when the pin 13 is smeared from the recess 19. Without the recess 19, the valve will be a self-closing valve.

Selv om håndtakets 11 stillinger som er tilordnet ventilens åpne eller stengte stilling, er forskjøvet 90° i forhold til hverandre slik at man etter håndtakets stilling kan se om ventilen er stengt eller åpen, kan spindelens 6 ende som vender bort fra ventillegemet 5, ytterligere være forsynt med et merkehode, 22 som ved åpnet ventil rager aksialt ut av håndtaket. Dette merkehode 22 kan være farvet, f.eks. overtrukket med en lysende farve. Although the handle's 11 positions, which are assigned to the valve's open or closed position, are offset by 90° in relation to each other so that one can see from the handle's position whether the valve is closed or open, the end of the spindle 6 facing away from the valve body 5 can further be provided with a marking head, 22 which, when the valve is open, protrudes axially from the handle. This marking head 22 can be colored, e.g. coated with a luminous colour.
