Description
Oppfinnelsen vedrorer en betjeningsmekanisme for dreining av en akseltapp, fortrinnsvis for et dreiespjeld, hvilken tapp strekker seg fra en stasjonær del på spjeldet og et med nevnte stasjonære del sammenkoblet hus som danner en sylinder, i hvilken et stempel av et trykkmedium kan forskyves aksialt og hvor sylinder og stempel er forsynt med samvirkende styreorganer slik at stempelet ved aksialbevegelse bibringes en rotasjonsbevegelse, og at stempelet videre er forbundet dreibart men aksialt forskyvbart med en koblingsdel for akseltappen, og hvor koblingsdelen gjennom en trykkmediumtett pakning rager inn i huset, og stempelet er hult og omslutter koblingsdelen. The invention relates to an operating mechanism for turning an axle pin, preferably for a rotary damper, which pin extends from a stationary part of the damper and a housing connected to said stationary part forming a cylinder, in which a piston of a pressure medium can be displaced axially and where cylinder and piston are provided with co-operating control devices so that the piston is imparted with a rotational movement during axial movement, and that the piston is further connected rotatably but axially displaceable with a coupling part for the axle pin, and where the coupling part projects into the housing through a pressure medium-tight gasket, and the piston is hollow and encloses the coupling part.
Fra tysk patent nr. 1.121.475 kjennes en mekanisme av den an-gitte art. Denne kjente mekanisme har en utadragende akseltapp. Derved vanskeliggjøres forbindelsen med f.eks. en dreiespjeldventil, som har en utadragende akseltapp. From German patent no. 1,121,475 a mechanism of the specified type is known. This known mechanism has a protruding axle pin. This makes the connection with e.g. a rotary damper valve, which has a protruding shaft pin.
Det for betjeningsmekanismen ifolge den foreliggende oppfinnelse karakteristiske er at koblingsdelen på i og for seg kjent måte er hul 'og utformet for opptagelse av akseltappen, og forbundet med stempelet ved hjelp av aksiale tenner. Derved lettes sammen-byggingen med f.eks. en dreiespjeldventil, som har en utadragende akseltapp, og der spares aksial byggelengde. What is characteristic of the operating mechanism according to the present invention is that the coupling part is, in a manner known per se, hollow and designed to accommodate the axle pin, and connected to the piston by means of axial teeth. This facilitates the joint construction with e.g. a rotary damper valve, which has a protruding shaft pin, and there is saved axial construction length.
Koblingsdelen og stempelorganet kan ifolge oppfinnelsen være forbundet med hverandre ved hjelp av aksiale tenner. Derved oppnås en lett mulighet for vinkeljustering under monteringen av betjeningsmekanismen på en spjeldventil. According to the invention, the coupling part and the piston member can be connected to each other by means of axial teeth. Thereby, an easy possibility of angle adjustment is achieved during the installation of the operating mechanism on a butterfly valve.
I det efterfolgende skal oppfinnelsen forklares nærmere under henvisning til tegningen, som viser en utforelsesform for en be- In what follows, the invention will be explained in more detail with reference to the drawing, which shows an embodiment of a
tjeningsmekanisme ifolge oppfinnelsen, delvis i lengdesnitt. operating mechanism according to the invention, partly in longitudinal section.
Den på tegningen viste betjeningsmekanisme har et stempelorgan The operating mechanism shown in the drawing has a piston member
1 med et stempel 8, som er forskyvbart i en sylinder 2. Stempelorganet har på sin nederste del utvendige, ikke selvsperrende gjenger 3, som samvirker med tilsvarende gjenger 4 på innsiden av sylinderen. Stempelorganet er hult og har innvendig en aksialt rillet overflate, hvori passer en tilsvarende rillet overflate 5 på en koblingsdel 6, som er fort inn i sylinderhuset gjennom en væsketett pakning 7. Når der tilfores trykkmedium til sylinderen 2 over eller under stempelet 8, vil dette beveges opp eller ned i sylinderen og derved dreies på grunn av innvirk-ningen mellom gjengene 4 og 5, og den oppståtte dreining vil over den rillede overflate 5 overfores til koblingsdelen 6. Dreiningsvinkelen i stempelets ene endestilling kan innstilles 1 with a piston 8, which is displaceable in a cylinder 2. The piston member has on its lower part external, non-self-locking threads 3, which interact with corresponding threads 4 on the inside of the cylinder. The piston member is hollow and internally has an axially grooved surface, in which a corresponding grooved surface 5 fits on a coupling part 6, which is quickly inserted into the cylinder housing through a liquid-tight seal 7. When pressure medium is supplied to the cylinder 2 above or below the piston 8, this is moved up or down in the cylinder and thereby rotated due to the interaction between the threads 4 and 5, and the resulting rotation will be transferred via the grooved surface 5 to the coupling part 6. The angle of rotation in one end position of the piston can be set
med et skrueorgan 9 i sylinderens overste endebunn. with a screw member 9 in the top end bottom of the cylinder.
Det vil forstås at betjeningsmekanismen ifolge oppfinnelsen vil kunne endres på mange måter for tilpasning til forskjellige formål. Istedenfor den rillede overflate 5 på koblingsdelen 6 It will be understood that the operating mechanism according to the invention will be able to be changed in many ways for adaptation to different purposes. Instead of the grooved surface 5 on the coupling part 6
kan der benyttes gjenger som samvirker med tilsvarende gjenger på den innvendige overflate av stempelorganet, og ved passende valg av stigningen og retningen av disse gjenger i forhold til dé utvendige gjenger på stempelorganet vil forholdet mellom de til akseltappen overforte dreiningskrefter og dreiningsvinkelen for denne derved kunne varieres innenfor meget vide grenser. threads can be used that cooperate with corresponding threads on the inner surface of the piston member, and by suitably choosing the pitch and direction of these threads in relation to the external threads on the piston member, the ratio between the turning forces transferred to the axle pin and the turning angle for this can thereby be varied within very wide limits.
Dette kan imidlertid også skje ved aksialt rillet ..overflate. En fordel med aksialt rillet overflate er at aksiallageret kun skal oppta de krefter som oppstår ved friksjonen mellom stempelorganet og koblingsdelen. However, this can also happen with an axially grooved ..surface. An advantage of an axially grooved surface is that the axial bearing must only absorb the forces arising from the friction between the piston member and the coupling part.
