Im Rohrleitungsbau, vor allem im Sanitärbereich, sind oft die Ventile, zumindest die Hauptabschlussventile, von Aussen nicht einsehbar hinter einer Installationswand versteckt. Die Befestigung und die Betätigung solcher Ventile muss an die Dicke der Installationswand angepasst werden können.In pipeline construction, especially in the sanitary sector, often the valves, at least the main shut-off valves, are hidden from the outside behind an installation wall. The attachment and operation of such valves must be able to be adapted to the thickness of the installation wall.

Aus der EP 854 243 B1 ist ein Unterputzventil bekannt. Das Unterputzventil wird an unterschiedlichen Dicken der Deckschichten angeglichen. Das Aussenrohr als wesentliche Befestigungsanordnung des Unterputzventils weist über die volle Länge ein Aussengewinde auf. Das Aussenrohr kann, damit das Aussengewinde nicht beschädigt wird, nur in Stufen von jeweils 5 mm an die gewünschte Länge angepasst werden. Eine weitere stufenlose Anpassung wird nur unter Zuhilfenahme zusätzlicher Hülsen erreicht. Die Betätigungsanordnung ist an einer ebenfalls in Längenstufen anpassbaren Betätigungsstange fest verbunden angeordnet.From the EP 854 243 B1 is a flush valve known. The flush valve is adapted to different thicknesses of the outer layers. The outer tube as the essential fastening arrangement of the flush valve has an external thread over the full length. The outer tube can be adjusted to the desired length only in increments of 5 mm so that the external thread is not damaged. Another continuous adjustment is achieved only with the help of additional sleeves. The actuator assembly is fixedly connected to a likewise adjustable in length stages operating rod.

DieThe DE 1 500 030DE 1 500 030 offenbart ein gattungsgemässes Unterputzventil bei dem das Aussenrohr komplett über die gesamte Länge durch das Aufliegen in der Wand abgestützt ist. Wodurch es den Einbau bei dünnen Wänden fast verunmöglich, da ein solcher Einbau zuwenig stabil wäre.discloses a generic flush valve in which the outer tube completely over the entire length by resting in the wall is supported. Which makes installation on thin walls almost impossible, as such an installation would be too little stable.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, ein System zur Befestigung und Betätigung eines hinter einer Installationswand angeordneten Unterputzventils anzugeben, das möglichst flexibel an die verschiedenen Ausführungen der Installationswände angepasst werden kann. Das System soll wahlweise auch unberechtigte oder unbefugte Betätigung des Unterputzventils verhindern.Based on this prior art, it is an object of the invention to provide a system for mounting and operating a mounted behind an installation wall flush valve, which can be adapted as flexibly as possible to the different versions of the installation walls. The system should also prevent either unauthorized or unauthorized operation of the flush valve.

Diese Aufgabe wird durch die Merkmalen des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Preferred developments of the invention will become apparent from the dependent claims.

Es ist von Vorteil, dass das System mit möglichst günstigen und handelsüblichen Elementen an unterschiedlichen Dicken der Installationswand angepasst werden kann. Dies wird dadurch erreicht, dass das Aussenrohr als ein glattes Rohr aus einem weichen Kunststoff, beispielsweise aus Polyäthylen ausgebildet ist. Dies wird auch dadurch erreicht, dass die Betätigungsstange als ein Sechskantrohr aus Leichtmetall ausgebildet ist. Solche Rohrleitungselemente sind günstig und handelsüblich, bedingen keine besondere Bearbeitung vor dem Einbau im System und können während des Einbaus nach Bedarf auf jeder beliebigen Länge abgeschnitten werden.It is advantageous that the system can be adapted with the most favorable and commercially available elements to different thicknesses of the installation wall. This is achieved in that the outer tube is formed as a smooth tube of a soft plastic, for example made of polyethylene. This is also achieved in that the actuating rod is designed as a hexagonal tube made of light metal. Such piping elements are cheap and commercially available, do not require any special processing before installation in the system and can be cut during installation to any length required.

Es ist auch von Vorteil, dass eine unbefugte Betätigung verhindert werden kann. Dies wird dadurch erreicht, dass das Handrad als eine Rosette mit einer zentral angeordneten Ausnehmung ausgebildet ist. Die Betätigungsstange weist eine Geometrie auf, die zu dieser Ausnehmung passt. Die Betätigungsstange kann einfach auf und/oder eingesteckt und, wenn eine Betätigung nicht erwünscht ist, auch wieder entfernt werden. Anstelle des Handrades kann auf dem handelsüblichen runden Kunststoffrohr während der Rohbauphase auch ein Blindstopfen aufgesteckt werden.It is also advantageous that unauthorized operation can be prevented. This is achieved by using the handwheel as a rosette with a central arranged recess is formed. The actuating rod has a geometry that fits this recess. The operating rod can be easily opened and / or inserted and, if an operation is not desired, also be removed again.

Die ringförmige Dichtung 23 verhindert, dass Wasser aus dem Sanitärraum in dem Zwischenraum zwischen dem Aussenrohr 10 und der Installationswand 2 eindringen kann.The annular part of the end nut 15 below the locking ring 25 fits in the likewise annular Wandabschlussflansch 14. The Wandabschlussflansch 14 is pressed by tightening the connection nut 15 fixed to the outside of the installation front wall 3. The Wandabschlussflansch 14 has on the front wall 3 side facing an annular projection 32, on the one in FIG. 1 apparent ring 33 can be attached as a medium marking 33 with a color to identify the flowing through the flush valve 20 medium. As medium marking 33, for example, a blue color for cold and a red color for warm water can be selected. Below the medium marking 33 is in FIG. 1 a closed-cell foam seal 23 is arranged. The annular seal Prevents water from the sanitary room in the space between the outer tube 10 and the installation wall 2 can penetrate.

In den Figuren 8 bis 10 ist die zweite Klemmverbindung 12 im Einzelnen dargestellt. Die zweite Klemmverbindung umfasst einen aus Kunststoff ausgebildeten geschlossenen Zugflansch 34 und einen offenen Klemmring 35. Der Klemmring 35 hat einen Innendurchmesser, der zum Aussendurchmesser des Aussenrohres 10 passt und weist auf der Innenseite eine Vielzahl von in mehreren Reihen angeordneten Zähnen 36 auf. Der offene Klemmring 35 mit den Zähnen 36 ist wiederum aus einem härteren Kunststoff als das Aussenrohr 10 hergestellt. Der Klemmring 35 weist auf der Aussenseite einen konischen Bereich 37 auf, der als Rampe oder Flanke zusammenwirkt mit einem weiteren ebenso konisch ausgebildeten Bereich 38 auf der Innenseite des Zugflansches 34.In the FIGS. 8 to 10 the second clamping connection 12 is shown in detail. The second clamping connection comprises a closed traction flange 34 made of plastic and an open clamping ring 35. The clamping ring 35 has an inner diameter which matches the outer diameter of the outer tube 10 and has a multiplicity of teeth 36 arranged in several rows on the inner side. The open clamping ring 35 with the teeth 36 is in turn made of a harder plastic than the outer tube 10. The clamping ring 35 has on the outside a conical region 37, which cooperates as a ramp or flank with another similarly conical region 38 on the inside of the pulling flange 34th

Der Klemmring weist einen Wulst 39 auf, mit der der Klemmring 35 bei der endgültigen Montage gegen axiale Verschiebung fest gehalten wird. Der Klemmring 35 weist auch eine in axialer Richtung verlaufende Vertiefung 40 auf, mit der der Klemmring 35 gegen Verdrehung gesichert wird. Die Vertiefung 40 und die Öffnung 41 des offenen Klemmringes 35 passen zu radialen Vorsprüngen 42, die an gegenüber liegenden Seiten auf der Innenseite des Zugflansches 34 ausgebildet sind. In Figur 10 ist der konische Bereich 38 des Zugflansches 34 ersichtlich. Wenn der offene Klemmring 35 in Bezug auf den geschlossenen Zugflansch 34 eine Bewegung in axialer Richtung ausführt, schliesst sich der Klemmring 35 und greifen die Zähne 36 in die Aussenwand des Aussenrohres 10 ein.The clamping ring has a bead 39, with which the clamping ring 35 is held firmly in the final assembly against axial displacement. The clamping ring 35 also has a recess 40 extending in the axial direction, with which the clamping ring 35 is secured against rotation. The recess 40 and the opening 41 of the open clamping ring 35 to radial projections 42 which are formed on opposite sides on the inside of the pull flange 34. In FIG. 10 is the conical portion 38 of the pull flange 34 can be seen. When the open clamping ring 35 performs a movement in the axial direction with respect to the closed pulling flange 34, the clamping ring 35 closes and engage the teeth 36 in the outer wall of the outer tube 10.

In Figur 11 ist der Bereich der zweiten Klemmverbindung 12 zusammen mit der Betätigungsstange 16 und dem Aussenrohr 10 im montierten Zustand geschnitten dargestellt. Der Zugflansch 34 weist drei Bohrungen 43 für Schrauben 44 auf, die den Zugflansch 34 bei der Endmontage von dem Befestigungsblech 7 der Installationswand 2 in axialer Richtung abheben. Der offene Klemmring 35 wird mit dem Wulst 39 in eine Öffnung im Befestigungsblech 7 gegen Verschiebung in axialer Richtung gehalten. Die konischen Bereiche 37,38 am Klemmring 35 und am Zugflansch 34 bewirken dass beim Anziehen der Schrauben 44 das Aussenrohr 10 In Bezug auf das Befestigungsblech 7 fest gehalten wird.In FIG. 11 the region of the second clamping connection 12 is shown cut together with the actuating rod 16 and the outer tube 10 in the mounted state. The pull flange 34 has three holes 43 for screws 44, which lift the pull flange 34 in the final assembly of the mounting plate 7 of the installation wall 2 in the axial direction. The open clamping ring 35 is with held the bead 39 in an opening in the mounting plate 7 against displacement in the axial direction. The conical regions 37, 38 on the clamping ring 35 and on the pull flange 34 cause that when tightening the screws 44, the outer tube 10 is held firmly in relation to the mounting plate 7.

In Figur 12 ist das System 1 zur Befestigung und Betätigung eines Unterputzventils 20 perspektivisch dargestellt. Das Aussenrohr 10 ist am Ende leicht aufgeweitet und mittels der ersten ringförmigen Klemmverbindung 11, hier dargestellt als eine Bride 11 fest mit dem Gehäuse 24 des Ventils 20 verbunden. Die erste Klemmverbindung 11 kann auch ohne Aufweitung des Ausserohres 10 und mit einem einfachen Klemmring 11 hergestellt werden. Hierzu wird dann das relativ dickwandige Aussenrohr 10 am Ende auf der Innenseite ausgedreht und auf dem Ventilgehäuse 24 gestülpt. Das Aussenrohr 10 ist mittels der zweiten Klemmverbindung 12 in Bezug auf das Befestigungsblech 7 der Installationswand 2 befestigt. Im Aussenrohr 10 ist die Betätigungsstange 16, hier das Sechskantrohr 16 aus Aluminium ersichtlich. In Figur 12 wurde die Vorwand 3 der Installationswand 2 weggelassen. Hiermit wird angedeutet, dass auch ohne Vorwand 3 eine ausreichende Befestigung des Unterputzventils 20 gegeben ist. Wenn kein Handrad 18 oder Rosette 18 gewünscht wird oder während der Rohbauphase kann die Betätigungsstange 16 weggelassen werden und kann das Aussenrohr 10 mit einem Blindstopfen abgeschlossen werden.In FIG. 12 the system 1 for attachment and operation of a flush valve 20 is shown in perspective. The outer tube 10 is slightly widened at the end and connected by means of the first annular clamping connection 11, shown here as a Bride 11 fixed to the housing 24 of the valve 20. The first clamp connection 11 can also be produced without widening the outer tube 10 and with a simple clamping ring 11. For this purpose, the relatively thick-walled outer tube 10 is then turned out at the end on the inside and slipped onto the valve housing 24. The outer tube 10 is fixed by means of the second clamping connection 12 with respect to the mounting plate 7 of the installation wall 2. In the outer tube 10, the actuating rod 16, here the hexagonal tube 16 made of aluminum can be seen. In FIG. 12 the pretext 3 of the installation wall 2 has been omitted. This is indicated that even without pretext 3 is a sufficient attachment of the flush valve 20 is given. If no handwheel 18 or rosette 18 is desired or during the shell construction phase, the actuating rod 16 can be omitted and the outer tube 10 can be completed with a blind plug.

Sowohl das Sechskantrohr 16 als auch das Aussenrohr 10 sind als Rohmaterial im Handel erhältlich und können auf jeder beliebigen Länge abgeschnitten werden. Hierdurch wird ein System 1 zur Betätigung und Befestigung eines Unterputzventils erreicht, dass einfach an jeder beliebigen Installation angepasst werden kann. Um unbefugte Betätigung des Unterputzventils 20 zu verhindern kann die Betätigungsstange 16, die lediglich auf die Ventilspindel 21 aufgesteckt wurde und die lediglich durch eine Steckverbindung mit dem Handrad 18 verbunden ist, wenn gewünscht entfernt werden.Both the hexagonal tube 16 and the outer tube 10 are commercially available as a raw material and can be cut to any length. As a result, a system 1 for operating and fixing a flush valve is achieved that can be easily adapted to any installation. In order to prevent unauthorized operation of the flush valve 20, the actuating rod 16, which has only been plugged onto the valve spindle 21 and which is merely connected by a plug connection with the handwheel 18, can be removed if desired.
