  • Figure 1 shows a concealed valve partially in longitudinal section;
  • Figure 2 shows a part of the flush valve according to Figure 1 with a modified protective sleeve part and extension piece.

Bei den beiden Ausführungsbeispielen in der Zeichnung sind gleiche oder entsprechende Elemente der Einfachheit halber mit jeweils gleichen Bezugszeichen versehen. Das in der Figur 1 gezeigte Unterputz-Ventil besteht aus einem Ventilgehäuse 1 mit Anschlußöffnungen 10 für 1/2"-Rohrleitungen. In dem Ventilgehäuse 1 ist ein normiertes Ventiloberteil 2 eingeschraubt, welches mit einem axial beweglichen Ventilteller 23 versehen ist, der mit einem im Ventilgehäuse 1 eingeschraubten Ventilsitz 11 zusammenwirkt. Durch Drehung einer Betätigungsspindel 21 wird hierbei die Axialbewegung des Ventiltellers 23 erzeugt. Neben dem vorstehend beschriebenen Ventiloberteil 2 können selbstverständlich auch entsprechend in den Außenabmessungen normierte Ventileinsätze mit Keramikventilscheiben angeordnet werden. Der Ventilein satz wird hierbei ebenfalls in das Ventilgehäuse 1 eingeschraubt und gelangt an dem Ventilsitz 11 zur dichten Anlage, wobei die Regelung des Durchflusses mit zueinander verdrehbaren, aneinanderliegenden, geschliffenen Keramikscheiben erfolgt.In the two exemplary embodiments in the drawing, the same or corresponding elements are provided with the same reference numerals for the sake of simplicity. 1 consists of a valve housing 1 with connection openings 10 for 1/2 " pipelines. A standardized upper valve part 2 is screwed into the valve housing 1, which is provided with an axially movable valve disk 23, which is provided with an in Valve housing 1 interacts with screwed-in valve seat 11. The axial movement of valve plate 23 is generated by rotating an actuating spindle 21. In addition to the valve upper part 2 described above, valve inserts with ceramic valve disks that are standardized in terms of their external dimensions can of course also be arranged 1 screwed in and arrives at the valve seat 11 for tight sealing, the flow being regulated with mutually adjoining, ground, ground ceramic disks.

An dem normierten Ventiloberteil 2 ist ein Verlängerungsstück 51 mit einer Verlängerungsspindel 5 sowie eine Schutzhülse 3 befestigbar. Die Schutzhülse 3 ist zweiteilig ausgebildet, wobei die untere Hülse 31 mit einem Feingewinde 24 fest auf das Ventiloberteil 2 aufschraubbar ist. Zur Durchführung des Schraubvorgangs sind im Mantel der Hülse 31 Radialbohrungen 34 ausgebildet. Koaxial zur Hülse 31 ist mit einer Aufnahmeöffnung 511 das Verlängerungsstück 51 mit Hilfe einer Riefenverzahnung 53 drehfest auf der Betätigungsspindel 21 angeordnet. Zur Axialsicherung sind außerdem im Verlängerungsstück 51 im Bereich der Aufnahmeöffnung 511 Schnappzungen 513 ausgebildet, mit denen das Verlängerungsstück 51 in der Stecklage auf der Betätigungsspindel 21 gesichert wird. Auf der Hülse 31 ist ein vorstehender Teil der Schutzhülse 3 als Kappe 32 ausgebildet und mittels Gewinde 33 teleskopartig aufschraubbar angeordnet. Koaxial in der Kappe 32 ist eine Verlängerungsspindel 5 an einer Schulter 322 mit Hilfe eines Sprengrings 55 axial festliegend, aber drehbar gelagert angeordnet. Die Verlängerungsspindel 5 weist dabei eine Axialöffnung 54 auf, in der eine Riefenverzahnung 53 ausgebildet ist, die zusammen mit der auf der Mantelfläche 512 des Verlängerungsstücks 51 ausgebildeten Riefenverzahnung 53 eine drehfeste, aber axial verschiebbare Kupplung der beiden Teile bewirkt. An der äußeren Mantelfläche der Kappe 32 ist außerdem ein Außenbund 321 ausgebildet, an dem sich eine auf der Mantelfläche verschiebbare Rosette 4 ab stützt. An der äußeren Stirnseite der Kappe 32 ist ferner ein Zapfen 52 an der Verlängerungsspindel 5 ausgebildet, auf dem ein Griffstück 6 mit Hilfe einer bekannten Isolier-und Schnapphalterung 61 fixiert ist.An extension piece 51 with an extension spindle 5 and a protective sleeve 3 can be attached to the standardized valve upper part 2. The protective sleeve 3 is formed in two parts, the lower sleeve 31 being securely screwed onto the valve upper part 2 with a fine thread 24. To carry out the screwing process 31 radial bores 34 are formed in the jacket of the sleeve. The extension piece 51 is arranged coaxially to the sleeve 31 with a receiving opening 511 in a rotationally fixed manner on the actuating spindle 21 by means of a serration 53. For axial securing, snap tongues 513 are also formed in the extension piece 51 in the area of the receiving opening 511, with which the extension piece 51 is secured in the plugged position on the actuating spindle 21. On the sleeve 31, a protruding part of the protective sleeve 3 is designed as a cap 32 and can be screwed on telescopically by means of thread 33. An extension spindle 5 is arranged coaxially in the cap 32 on a shoulder 322 with the aid of a snap ring 55, axially fixed but rotatably mounted. The extension spindle 5 has an axial opening 54 in which a serration 53 is formed which, together with the serration 53 formed on the lateral surface 512 of the extension piece 51, causes a rotationally fixed but axially displaceable coupling of the two parts. On the outer circumferential surface of the cap 32, an outer collar 321 is also formed, on which a movable rosette 4 is supported on the outer surface. On the outer end face of the cap 32, a pin 52 is also formed on the extension spindle 5, on which a handle 6 is fixed with the aid of a known insulating and snap holder 61.

Bei der Montage des Unterputz-Ventils wird zunächst die untere Hülse 31 auf das Ventileinsatzgehäuse 22 geschraubt und das Verlängerungsstück 51 auf die Betätigungsspindel 21 gesteckt. Nunmehr wird die Kappe 32 mit der Verlängerungsspindel 5 und der Rosette 4 soweit auf die Hülse 31 mit dem Gewinde 33 aufgeschraubt, bis die Rosette 4 fest an der Gebäudewand 7 aufliegt und die Gebäudewandöffnung verschließt, wodurch gewährleistet ist, daß der Abstand der Ventilbetätigungseinrichtung von der Wandoberfläche unabhängig von der Ventileinbautiefe ist. Außerdem wird die Schraubverbindung des Gewindes 33 durch diese Anordnung gesichert und die Schutzhülse 3 abgestützt. Nunmehr kann das Griffstück 6 mit Hilfe der Isolier-und Schnapphalterung 61 auf den Zapfen 52 aufgesteckt werden, worauf dann das Unterputz-Absperrventil betriebsbereit ist. Die Schutzhülse 3 sowie das Verlängerungsstück 51 und die Verlängerungsspindel 5 sind so ausgelegt, daß die normal auftretenden Einbautiefen von X bis Y bei Unterputz-Ventilen (z.B. 50 bis 80 mm) stufenlos einstellbar sind.When installing the flush-mounted valve, the lower sleeve 31 is first screwed onto the valve insert housing 22 and the extension piece 51 is plugged onto the actuating spindle 21. Now the cap 32 with the extension spindle 5 and the rosette 4 is screwed onto the sleeve 31 with the thread 33 until the rosette 4 lies firmly against the building wall 7 and closes the building wall opening, thereby ensuring that the distance of the valve actuating device from the Wall surface is independent of the valve installation depth. In addition, the screw connection of the thread 33 is secured by this arrangement and the protective sleeve 3 is supported. Now the handle 6 can be plugged onto the pin 52 with the aid of the insulating and snap holder 61, whereupon the flush-mounted shut-off valve is ready for operation. The protective sleeve 3 and the extension piece 51 and the extension spindle 5 are designed so that the normal installation depths from X to Y for flush-mounted valves (e.g. 50 to 80 mm) are infinitely adjustable.

In Figur 2 ist eine abgewandelte Ausführung des in Figur 1 gezeigten Unterputz-Ventils dargestellt. Hierbei ist eine untere Hülse 31 a und ein Verlängerungsstück 51 a vorgesehen, die beide die gleiche Vorkraglänge aufweisen. Auf der Hülse 31a ist das Gewinde 33 mit einer Ringnut 331 unterteilt. Die Abmessungen der Schutzhülse 3 sowie der Verlängerungsspindel 5 mit dem Verlängerungsstück 51 a sind hierbei so ausgelegt, daß eine stufenlose Verstellung von 80 bis 50 mm Einbautiefe (Y bis X) ermöglicht ist. Bei Sondereinbaufällen kann es jedoch vorkommen, daß nur eine Einbautiefe bis zu 20 mm erzielbar ist. Für diesen Fall kann z.B. vor der Installation des Unterputz-Ventils die Hülse 31 a zusammen mit dem Verlängerungsstück 51 a im Bereich der Ringnut 331 abgetrennt werden. Hiernach ist dann eine stufenlose Einstellung von X bis Y z.B. von 20 bis 50 mm möglich. Um eine relativ einfache Abtrennung zu ermöglichen, können zweckmäßig das Stützrohr 3 und das Verlängerungsstück 51a aus Kunststoff im Spritzgießverfahren hergestellt werden.FIG. 2 shows a modified version of the concealed valve shown in FIG. 1. Here, a lower sleeve 31 a and an extension piece 51 a are provided, both of which have the same protruding length. The thread 33 is divided on the sleeve 31a by an annular groove 331. The dimensions of the protective sleeve 3 and the extension spindle 5 with the extension piece 51 a are designed so that a continuous adjustment of 80 to 50 mm installation depth (Y to X) is possible. In special installation cases, however, it is possible that only an installation depth of up to 20 mm can be achieved. In this case, the sleeve 31 a can be separated together with the extension piece 51 a in the region of the annular groove 331, for example before the flush-mounted valve is installed. Then there is a continuous setting from X to Y, for example from 20 to 50 mm possible. In order to enable a relatively simple separation, the support tube 3 and the extension piece 51a can expediently be produced from plastic in an injection molding process.
