Description

147516147516

Den foreliggende opfindelse angår en ventil af drejety-pen, såsom kugleventiler eller haner, og af den art, der omfatter et ventilhus med mindst to tilslutningsåbninger og en åbning for en ventilspindel til drejning af et drejeligt lejret ventillegeme om en drejningsakse til mindst én lukket og én åben ventilstilling, hvor ventillegemet har et med mindst én boringsåbning forsynet ækvatorialområde, der ved ventillegemets drejning om sin drejningsakse successivt føres forbi en tætningsring ved en af ventilhusets tilslutningsåbninger.The present invention relates to a type of valve, such as ball valves or taps, and of the type comprising a valve housing with at least two connection openings and an opening for a valve stem for rotating a rotatably mounted valve body about a axis of rotation to at least one closed and one open valve position, wherein the valve body has an equatorial region provided with at least one bore opening, which, when turning the valve body about its axis of rotation, is successively passed by a sealing ring at one of the valve housing connection openings.

Ventilen ifølge opfindelsen er ejendommelig ved, at ventillegemet i en lukket ventilstilling ligger an mod tætningsringen langs et ringformet berøringsområde, der befinder sig i større afstand fra ventillegemets drejningsakse end ventillegemets overflade andre steder i ækvatorialområdet.The valve according to the invention is characterized in that the valve body in a closed valve position abuts against the sealing ring along an annular contact area which is at a greater distance from the axis of rotation of the valve body than the surface of the valve body elsewhere in the equatorial region.

Derved tilvejebringes en ventil af nævnte art, som i en åben ventilstilling har ingen eller forholdsvis ringe friktionsmodstand mod drejning i retning mod en lukket ventilstilling, fordi ventillegemets indgreb med tætningsringen sker under et lavere anlægstryk end det, som forekommer i ventilens lukkede stilling. Derved tilvejebringes en ventil med længere driftslevetid før udskiftning af tætningsring, både på grund af det ringere tryk mod tætningsringen i ventilens åbne stilling og på grund af, at kanterne på ventillegemets boringsåbning passerer tætningsringen under væsentligt lavere tryk imod denne, end det tryk ventillegemet udøver i ventilens lukkede stilling. Anlægstrykket mod tætningsringen kan på grund af ventilens konstruktion i ventilens lukkede stilling være væsentligt højere end de hidtil kendte anlægstryk i sådanne ventiler, der sædvanligvis har et tætningsanlægstryk af en sådan størrelsesorden, at der til lukning af ventilen på dennes ventilspindel højst skal udøves et drejningsmoment på 75 Nm, medens ventilen iføl- 147516 2 ge opfindelsen kan opnå et tætningstryk, hvortil der skal anvendes et drejningsmoment på ventilspindelen af størrelsesordenen 350 Nm, d.v.s. et tætningstryk, som er ca. 5 gange større end hidtil opnået i kugleventiler eller haner.Thereby, a valve of said kind is provided which, in an open valve position, has no or relatively low frictional resistance to rotation in the direction of a closed valve position, because the engagement of the valve body with the sealing ring occurs at a lower abutment pressure than that occurring in the closed position of the valve. This provides a valve with longer service life before replacing the sealing ring, both because of the lower pressure against the sealing ring in the open position of the valve and because the edges of the valve body bore opening pass the sealing ring under substantially lower pressure than the pressure exerted by the valve body. the closed position of the valve. Due to the design of the valve in the closed position of the valve, the system pressure against the sealing ring can be substantially higher than the known abutment pressures in such valves, which usually have a sealing system pressure of such magnitude that a maximum torque of at least one torque of the valve spindle must be exerted. 75 Nm, while the valve of the invention can achieve a sealing pressure to which a torque is applied to the valve spindle of the order of 350 Nm, i.e. a sealing pressure which is approx. 5 times greater than previously achieved in ball valves or taps.

Ved ventilen ifølge opfindelsen kan hver ækvatorialområde-del med nævnte største afstand til ventillegemets centrum eller drejningsakse være bredere end tætningsringens største diameter for denne rings berøringsflade med ventillegemet. Derved sikres, at hele tætningsringens berøringsflade får samme tætningstryk eller anlægstryk mod ventillegemet i lukkestillingen.In the valve according to the invention, each equatorial area portion with said greatest distance to the center of the valve body or axis of rotation may be wider than the largest diameter of the sealing ring for the contact surface of this ring with the valve body. This ensures that the entire contact surface of the sealing ring receives the same sealing pressure or abutment pressure against the valve body in the closing position.

Hvor ventilen er af hanetypen med cylindrisk eller kegleformet ventillegeme, kan ved ventilen ifølge opfindelsen ventillegemets ækvatorialområde, d.v.s. nævnte område, der ved ventilens drejning passerer tætningsringens berøringsområde, være sammensat af parvis modsat beliggende cylinder- eller keglefladedele af parvis samme form, samtidig med at mindst ét par af nævnte modstående cylinder- eller keglefladedele har fælles akse og større afstand til ventillegemets drejningsakse end de øvrige par af nævnte cylindereller keglefladedele. Derved præciseres en foretrukken udførelsesform for opfindelsens anvendelse i ventiler af hanetypen.Where the valve is of the male type with cylindrical or cone-shaped valve body, the valve according to the invention may have the equatorial region of the valve body, i.e. said region passing through the contact area of the valve ring when rotating the sealing ring is composed of pairs of opposite cylindrical or conical surface portions of the same shape, while at least one pair of said opposite cylinder or conical surface portions have a common axis and a greater distance from the axis of rotation of the valve body. other pairs of said cylinder or cone surface parts. Thereby, a preferred embodiment of the invention is specified in male-type valves.

Hvor ventilen er en kugleventil, kan ved ventilen ifølge opfindelsen ventillegemets ækvatorialområde være sammensat af parvis modsat beliggende kuglefladedele af parvis samme overfladekrumning, samtidig med at mindst ét par af nævnte modstående kuglefladedele har samme centrum og større afstand til kuglens centrum end de øvrige par kuglefladedele. Derved præciseres en foretrukken udførelsesform for en modificeret kugleventil, idet ventillegemet kun for en del af sit ækvatorialområde behøver at have centrum i ventilens drejningsakse.Where the valve is a ball valve, in the valve according to the invention the equatorial region of the valve body may be composed of pairs of oppositely located ball surface portions of pairs of the same surface curvature, while at least one pair of said opposing ball surface portions have the same center and greater distance from the center of the ball than the other pairs of ball portions. Thereby, a preferred embodiment of a modified ball valve is clarified, since the valve body only needs to have the center of the valve axis of rotation for part of its equatorial range.

Opfindelsen vil i det følgende blive nærmere forklaret i forbindelse med nogle udførelseseksempler og under henvisning til tegningen, hvor fig. 1 viser et ventillegeme ifølge opfindelsen, fig. 2 det i fig. 1 viste legeme set fra siden, fig. 3 det i fig. 1 viste set forfra, fig. 4 et snit langs I-I i fig. 3 gennem en ændret udførelsesform, fig. 5 et snit langs II-II i fig. 3, fig. 6 en udførelsesform med plane flader ved boringen, og fig. 7 en tætningsring.The invention will be explained in more detail below with reference to some embodiments and with reference to the drawing, in which fig. 1 shows a valve body according to the invention; FIG. 2 shows the embodiment of FIG. 1 is a side view of the body; FIG. 3 shows the embodiment of FIG. 1, FIG. 4 is a section along I-I of FIG. 3 through a modified embodiment; 5 is a section along II-II of FIG. 3, FIG. 6 shows an embodiment with planar surfaces at the bore; and FIG. 7 a sealing ring.

Fig. 1 viser et ventillegeme 1 ifølge opfindelsen af kugletypen. Ventillegemets boring 2 har en åbning beliggende ved en kuglefladedel 3, som har mindre afstand til kuglens centrum end en kuglefladedel 4, hvori ingen boringsåbninger findes. Øverst er ventillegemet forsynet med en flade 5, i hvis midte er udformet et kasseformet fremspring 6 til at gå i indgreb med en gennem det ikke viste ventilhus forløbende ventilspindel, der ved sin indgrebsende er forsynet med en komplementært til fremspringet 6 udformet kærv, fordybning eller hul.FIG. 1 shows a valve body 1 according to the invention of the ball type. The valve body bore 2 has an opening located at a ball face portion 3 which is less spaced to the center of the ball than a ball face portion 4 in which no bore openings are found. At the top, the valve body is provided with a surface 5, in the middle of which is a box-shaped projection 6 for engaging a valve spindle extending through the valve housing not shown, which is provided at its engagement end with a groove, groove or complementary to the projection 6. hole.

Fig. 2 viser samme ventillegeme set fra siden med afrundede overgange mellem de to flader 3 og 4. Denne ventil er af én-vejs ventiltypen med en enkelt boring i ventillegemet, men opfindelsen kan også udøves med to-vejs og trevejs ventiltyper af såvel hane- som kugletypen. Ventillegemet 1 drejes om dets drejningsakse 7, og kuglefladen 4 har centrum i ventillegemets centrum 8. I dette tilfælde er kuglens centrum beliggende, hvor drejningsaksen 7 4 1Λ7516 skærer boringens 2 akse 9. I fig. 2 er indtegnet ventillegemets ækvatorialområde 10, det område, som under ven-tillegemets 1 drejning successivt føres forbi en tætningsring i ventilhuset. Et eksempel på en tætningsring 12 er vist i fig. 7, hvor tætningsringens berøringsflade eller anlægsflade 14 til tætning mod ventillegemet i dettes lukkede stilling er vist skrånende i forhold til tætningsringens plan. Et indvendigt fremspring 16 på tætningsringen 12 har vist sig i ventilens åbne stilling at fjerne ventilstøj i de udførelsesformer for ventillegemet, hvor fladen 3 også bringes i indgreb med tætningsringen 12, omend under et ringere anlægstryk, på grund af, at fladen 3 befinder sig i mindre afstand fra drejningsaksen 7 end fladen 4.FIG. 2 shows the same valve body as seen from the side with rounded transitions between the two faces 3 and 4. This valve is of one-way valve type with a single bore in the valve body, but the invention can also be practiced with two-way and three-way valve types of both male and female. ball type. The valve body 1 is rotated about its axis of rotation 7, and the ball face 4 is centered in the center of the valve body 8. In this case, the center of the ball is located, where the axis of rotation 7 4 1Λ7516 intersects the axis 9 of the bore. 2, the equatorial region 10 of the valve body is plotted, the area which, during the rotation of the friend body 1, is successively passed by a sealing ring in the valve housing. An example of a sealing ring 12 is shown in FIG. 7, wherein the contact surface of the sealing ring or abutment surface 14 for sealing against the valve body in its closed position is shown inclined relative to the plane of the sealing ring. An internal projection 16 of the sealing ring 12 has been found in the open position of the valve to remove valve noise in the embodiments of the valve body, where the surface 3 is also engaged with the sealing ring 12, albeit under a lower abutment pressure, because the surface 3 is in the less distance from the axis of rotation 7 than the surface 4.

Fig. 3 viser ventillegemet 1 set forfra, ligeledes med ækvatorialområdet 10 vist.FIG. 3 is a front elevational view of the valve body 1 as well as the equatorial region 10 shown.

Fig. 4 viser et snit langs I-I i fig. 3 igennem en udførelsesform, hvor fremspringet 6 er erstattet af en udsparing 18 til indgreb med ventilspindelen. Her er med stiplet linie vist den sædvanlige tværsnitskontur 20 for en normal kugleventil, hvorved det lettere forstås, hvorfor ventillegemet 1 ifølge opfindelsen ligger an mod ventilhusets tætningsring 12 med et ringere anlægstryk i ventilens åbne stilling end i dennes lukkede stilling.FIG. 4 shows a section along I-I in FIG. 3 through an embodiment in which the projection 6 is replaced by a recess 18 for engagement with the valve stem. Here is shown in dotted line the usual cross-sectional contour 20 for a normal ball valve, whereby it is more easily understood why the valve body 1 according to the invention abuts against the sealing ring 12 of the valve housing with a lower abutment pressure in the open position of the valve than in its closed position.

Fig. 5 viser et snit langs II-II i fig. 3 midt igennem ventillegemets 1 ækvatorialområde 10. Med streg-prik-linien 22 er antydet ventillegemets 1 bane for kuglefladedelen 4.FIG. 5 shows a section along II-II in FIG. 3 through the equatorial region of the valve body 1 with the dash-dot line 22 is indicated the path of the valve body 1 for the ball face portion 4.

Fig. 6 viser en udførelsesform for ventillegemet 1, hvor kun fladedelene 4 er kugleformede med afrundede overgange til de plane flader 26, hvori ventillegemets boring 2 udmunder, og hvor en flade 24 modsat fladen 5 også er plant udformet. Afstanden mellem fladerne 5 og 24 svarer til ækvatorialområdets 10 bredde. Derved kan opnås en ventil- 147516 5 hus med lav byggehøjde, og hvor alle opfindelsens fordele er udnyttet.FIG. 6 shows an embodiment of the valve body 1 in which only the surface parts 4 are spherical with rounded transitions to the planar surfaces 26, in which the bore 2 of the valve body opens, and in which a surface 24 opposite the surface 5 is also formed flat. The distance between the faces 5 and 24 corresponds to the width of the equatorial region 10. Thereby a low housing height valve housing can be obtained and all the advantages of the invention are utilized.

De afrundede overgange til fladerne 26 giver mindre slitage på tætningsringen 12 end rundingskanter på boringsmundinger i ventillegemet.The rounded transitions to the faces 26 provide less wear on the sealing ring 12 than the rounding edges of bore openings in the valve body.

Hvor mere end én boring findes i ventillegemet 1, skal der i dettes ækvatorialområde 10 være mindst én boringsåbnings-fri overfladedel af en større bredde, målt langs ventillegemets 1 omkreds ved ækvatorialområdet 10, end tætningsringens 12 største diameter for dens berøringsområde 14 med ventillegemet 1. Det vil sige, at berøringsområdet 14 er mindre end den berøringsåbningsfri overfladedel. Ventilhusets tilslutningsåbninger, som kan afspærres af boringsåbningsfri overfladedele på ventillegemet 1, er alle beliggende radialt ud for ækvatorialområdet 10, men ventilhuset kan også have andre tilslutningsåbninger, f.eks. en anbragt modsat ventilhusets åbning ventilspindlen.Where more than one bore is provided in the valve body 1, in its equatorial region 10 there must be at least one bore-free surface portion of a larger width, measured along the circumference of the valve body 1 at the equatorial region 10, than the largest diameter of the sealing ring 12 for its contact area 14 with the valve body 1. That is, the contact area 14 is smaller than the contact opening-free surface portion. The valve housing connection openings, which can be blocked by bore-free surface portions of the valve body 1, are all located radially off the equatorial region 10, but the valve housing may also have other connection openings, e.g. one positioned opposite the valve housing opening valve stem.
