Description

DK 154242 BDK 154242 B

Opfindelsen angår en tætningsanordning af den. i hovedkravets indledning angivne art.The invention relates to a sealing device thereof. specified in the introduction of the main claim.

Ved ventiler med keramiske ventilelementer er det kendt at anbringe tilslutningstætningerne som separate elemen-5 ter i en specielt udformet bunddel af et patronlignende hus, som kan indsættes i armaturer med til- og afløbskanaler. Det er også kendt at udforme patronhusets bunddel således, at der på den ene side mellem bunden og det keramiske ventilelement kan arrangeres et sæt tætningsor-10 ganer og på den anden side mellem bunden og armaturet kan arrangeres et andet sæt tætningsorganer.In the case of valves with ceramic valve elements, it is known to place the connection seals as separate elements in a specially designed bottom part of a cartridge-like housing, which can be inserted into luminaires with inlet and outlet ducts. It is also known to design the bottom portion of the cartridge housing such that on one side between the bottom and the ceramic valve member a set of sealing means can be arranged and on the other side between the bottom and the luminaire a second set of sealing means can be arranged.

Disse kendte tætningsaggregater kræver hvert en speciel bunddel til patronhuset, som f.eks. for at lette montering og demontering i armaturerne er forbundet med patronhu-15 set ved hjælp af svejsning, snapelementer eller friktion. Tætningsorganerne har derved to funktioner, nemlig på den ene side at garantere en sikker tætning og på den anden side at udligne fremstillingstolerancer, som uundgåeligt optræder ved fremstillingen af de enkelte ventilelementer 20 og af huset, og at sammenpresse de keramiske ventilelementer med en bestemt forspænding. Forårsaget af toleranceudligningen for enkeltdelene kommer det derved hyppigt til en forøget tilpresning af de keramiske elementer, hvilket fører til en Uønsket tunggang af ventilen.These known sealing assemblies each require a special bottom portion for the cartridge housing, such as e.g. to facilitate mounting and disassembly of the luminaires is connected to the cartridge housing by means of welding, snap elements or friction. The sealing means thereby have two functions, namely, on the one hand, to guarantee a secure seal and on the other to offset manufacturing tolerances that inevitably occur in the manufacture of the individual valve elements 20 and of the housing, and to compress the ceramic valve elements with a certain bias. As a result of the tolerance equalization of the individual parts, it frequently results in an increased compression of the ceramic elements, which leads to an undesirable heavy duty of the valve.

25 Det er formålet med opfindelsen at tilvejebringe en forbedret tætningsudformning til ventiler af den ovenfor beskrevne art.It is an object of the invention to provide an improved sealing design for valves of the kind described above.

Dette opnås ifølge opfindelsen ved at tilvejebringe en tætningsanordning, som er ejendommelig ved det i krav 30 1' s kendetegnende del angivne.This is achieved according to the invention by providing a sealing device which is characterized by the characterizing part of claim 30 1.

Yderligere udformninger ifølge opfindelsen er angivet i kravene 2-5.Further embodiments of the invention are set forth in claims 2-5.

De med opfindelsen opnåede fordele består især i, at det keramiske element kan frembringes i ét stykke med tætningsorganet, f.eks. ved påvulkanisering. De hidtil nødvendige, separate tætningsorganer samt de til holdning 5 eller støtning af tætningsorganerne nødvendige dele kan bortfalde. Desuden kan på simpel måde det på det keramiske element umiddelbart udformede tætningsorgan designes som formtætning, læbetætning, således at den ved fremstillingstolerancerne forårsagede forskellige tilpresning af 10 de keramiske ventilelementer i det mindste væsentligt reduceres.The advantages of the invention in particular consist in the fact that the ceramic element can be produced in one piece with the sealing means, e.g. by vulcanization. The necessary separate sealing means as well as the parts necessary for position 5 or support of the sealing means may lapse. In addition, in the simple manner, the immediately formed sealing member of the ceramic element can be designed as mold seal, lip seal, so that at the manufacturing tolerances, various compression of the ceramic valve elements can be at least substantially reduced.

Som resultat af forholdsreglerne ifølge opfindelsen kan derudover den samlede ventilpatronudformning forenkles, hvorved især også monteringen af patronen gøres lettere, 15 således at der opnås en specielt billig udførelse.In addition, as a result of the precautionary measures of the invention, the overall valve cartridge design can be simplified, whereby the mounting of the cartridge in particular is also facilitated, so that a particularly inexpensive embodiment is obtained.

Et udførelseseksempel på opfindelsen vil nu blive nærmere forklaret under henvisning til tegningen, på hvilken: fig. 1 viser et længdesnit gennem en blandingsventilpa-tron til sanitetsarmaturer, og 20 fig. 2 viser blandingsventilpatronen ifølge fig. 1 set nedenfra.An embodiment of the invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 is a longitudinal section through a mixer valve assembly for sanitary fittings; and FIG. 2 shows the mixing valve cartridge of FIG. 1 from below.

I et cylindrisk patronhus 1, som kan indsættes i en tilsvarende anbringelsesboring i sanitetsarmaturer (ikke vist på tegningen) og fastgøres ved hjælp af spændskru-25 er 11, er der vinkelret på længdeaksen 2 anbragt et oxidkeramisk ventilelement 3 stift holdt i patronhuset 1, hvilket ventilelement har to indgangsåbninger 31 for koldt og varmt vand og en udgangsåbning 32 for blandingsvandet. På den mod strømmen vendende endeflade af det 30 oxidkeramiske ventilelement 3 er der påvulkaniseret et tætningsorgan 33, som også delvis strækker sig over elementets cylindriske overflade. På den fra det oxidkera- 3In a cylindrical cartridge housing 1, which can be inserted into a corresponding placement bore in sanitary fittings (not shown in the drawing) and secured by clamping screws 11, an oxide ceramic valve member 3 is mounted rigidly in the cartridge housing 1, which valve member has two inlet openings 31 for cold and hot water and an outlet opening 32 for the mixing water. On the end-facing surface of the oxide ceramic valve member 3, a sealing member 33 is also vulcanized, which also partly extends over the cylindrical surface of the member. On it from the oxide core 3

Patronhuset 1 er i det væsentlige udformet som en cylindrisk 10 i'ndhylning og bærer på den fra det oxidkeramiske ventillegeme 3 bortvendte endeflade et koaksialt monteret dreje-:e.lement 5, i hvilket en vinkelret på længdeaksen 2 sving-;bflirt lejret toarmet indstillingsstang 6 er monteret. Den en:e ii.Mts-tillingsarm er ved hjælp af en tap 61 forbundet 15 med et s’tiyieelement 41 for reguleringselementet 4, medens den anden indstillingsarm er forbundet med et betjeningshåndtag (ikke vist på tegningen). Styreelementet 41 holdes derudover i en radialføring af drejeelementet 5, således at ved drejning af indstillingsa-r.me.ra 6 dre-20 jes reguleringselementet 4 tilsvarende via drejeelementet 5 eller forskydes ved en svingning af indstillings-armen 6 radialt i drejeelementets 5 føring. Ved en tilsvarende anordning af indløbs- og udløbsåbningerne 31, 32 i det oxidkeramiske ventilelement 3 og ved positionering 25 af en overstrømningskanal 42 i reguleringselementet 4 kan ved en drejning af indstillingsarmen 6 blandingsforholdet og ved en svingning af indstillingsarmen 6 gennemstrømningsmængden gennem ventilen bestemmes.The cartridge housing 1 is substantially shaped as a cylindrical casing 10 and carries on the end surface facing away from the oxide-ceramic valve body 3 a coaxially mounted pivot member 5, in which a perpendicular to the longitudinal axis 2 is pivoted; 6 is mounted. The second adjusting arm is connected by means of a pin 61 to a side element 41 of the control element 4, while the other setting arm is connected to a control handle (not shown in the drawing). In addition, the control element 41 is held in a radial guide of the rotating element 5, so that when the adjusting spacer 6 is rotated, the control element 4 is rotated correspondingly via the rotating element 5 or is displaced radially in the guide element of the rotating element 5. By a corresponding arrangement of the inlet and outlet openings 31, 32 of the oxide ceramic valve element 3 and by positioning 25 of an overflow channel 42 in the control element 4, the mixing ratio and by a swing of the adjusting arm 6 the flow rate through the valve can be determined.

Naturligvis kan tætningsanordningen f.eks. også realise-30 res med én eller flere indløbsåbninger.Of course, the sealing device can e.g. also be realized with one or more inlet openings.
