Description

Die vorliegende Erfindung bezieht sich auf eine frostsichere Wasserarmatur nach dem Gattungsbegriff des Patentanspruches 1.The present invention relates to a frost-proof water tap according to the Generic term of patent claim 1.

Bei einer solchen Armatur, wie sie aus dem DE-U1-298 20 782 bekannt ist, muß sichergestellt werden, daß der der Außentemperatur und damit unter Umständen dem Frost ausgesetzte Teil der Armatur bei abgesperrtem Ventil entlüftet wird, so daß es sich vollständig entleert und bei Frost nicht bersten kann. Ferner soll sichergestellt sein, daß beim Abbrechen des nach außen ragenden Teils der Armatur, z. B. infolge Vandalismus, die Schließstellung des in der Armatur enthaltenen Ventils beibehalten wird.With such a valve, as is known from DE-U1-298 20 782, must Ensure that the outside temperature and possibly the frost exposed part of the valve is vented with the valve shut off, so that it completely emptied and cannot burst in frost. It should also be ensured that when breaking off the protruding part of the fitting, e.g. B. due to vandalism The closed position of the valve contained in the valve is maintained.

Dies wird bei einer gattungsgemäßen Wasserarmatur durch die kennzeichnenden Merkmale des Patentanspruches 1 bewerkstelligt. Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen frostsicheren Wasserarmatur können den abhängigen Ansprüchen entnommen werden.This is the characteristic of a generic water fitting Features of claim 1 accomplished. Further advantageous embodiments of the Frost-proof water fitting according to the invention can the dependent claims be removed.

Anhand der einzigen Figur der beiliegenden Zeichnung sei im folgenden ein Ausführungsbeispiel der erfindungsgemäßen Wasserarmatur beschrieben, wobei diese Figur einen Axialschnitt durch die erfindungsgemäße Wasserarmatur zeigt.Based on the single figure of the accompanying drawing, one is in the following Embodiment of the water fitting according to the invention described, this Figure shows an axial section through the water fitting according to the invention.

Gemäß dieser Figur ist eine Wasserarmatur 10 in Form eines Absperrhahnes durch eine Wand 12 geführt, wobei eine Innenwand 14 einen frostsicheren Innenraum abgrenzt und eine Außenwand 16 den frostgefährdeten Außenbereich abgrenzt. Die Armatur 10 umfaßt ein Innengehäuse 18 und ein Außengehäuse 20, wobei sich das Innengehäuse 18 mit einem rohrförmigen Ansatz 22 in das Außengehäuse 20 erstreckt. Auf dem rohrförmigen Ansatz 22 wird das Außengehäuse 20 mittels eines Klemmringes 24 und einer Überwurfmutter 26 verschiebbar befestigt und abgedichtet. Das Innengehäuse 18 und das Außengehäuse 20 geben im Innern einen Hohlraum 28 vor. In diesen Hohlraum 28 ragt von außen eine Ventilspindel 30, wobei die Ventilspindel 30 mit einem Außengewinde 32 in ein Innengewinde 34 des Außengehäuses 20 greift, so daß sie bei einer Drehung eine Verschiebung erfährt. Die Ventilspindel 30 weist an ihrem vorderen Ende eine Mehrkant- Ausnehmung 36 auf, in die eine Verbindungsstange 38 eingreift, deren Querschnitt als passender Mehrkant ausgebildet ist. Das andere Ende der Verbindungsstange 38 greift in eine Mehrkant-Ausnehmung 40 in einem Ventilkegel 42, der mit einem Außengewinde 44 in einem Innengewinde 46 im Innengehäuse 18 durch Verschraubung axial verschiebbar ist und in der Schließstellung an einem Ventilsitz 48 im Innengehäuse 18 zur Anlage gelangt, wobei eine in den Ventilkegel 42 eingelegte Weichdichtung 50 die Abdichtung übernimmt. Der Ventilkegel 42 ist über einen Teil seines Umfanges mit einer oder mehreren Abflachungen 58 versehen, um bei geöffnetem Ventil 42, 48 einen ungehinderten Durchgang des Wassers zu ermöglichen.According to this figure, a water fitting 10 in the form of a shut-off valve is guided through a wall 12 , an inner wall 14 delimiting a frost-proof interior and an outer wall 16 delimiting the frost-prone outside area. The fitting 10 includes an inner housing 18 and outer housing 20 with the inner housing 18 extends with a tubular extension 22 into the outer housing twentieth On the tubular extension 22 , the outer housing 20 is slidably secured and sealed by means of a clamping ring 24 and a union nut 26 . The inner housing 18 and the outer housing 20 provide a cavity 28 in the interior. A valve spindle 30 protrudes from the outside into this cavity 28 , the valve spindle 30 engaging with an external thread 32 in an internal thread 34 of the outer housing 20 , so that it undergoes a displacement upon rotation. The valve spindle 30 has at its front end a polygonal recess 36 into which a connecting rod 38 engages, the cross section of which is designed as a suitable polygon. The other end of the connecting rod 38 engages in a polygonal recess 40 in a valve cone 42 , which can be axially displaced by screwing with an external thread 44 in an internal thread 46 in the inner housing 18 and comes into contact with a valve seat 48 in the inner housing 18 in the closed position, wherein a soft seal 50 inserted into the valve cone 42 takes over the sealing. The valve cone 42 is provided over one part of its circumference with one or more flats 58 in order to allow unimpeded passage of the water when the valve 42 , 48 is open.

Die Gewinde 32, 34 und 44, 46 können unterschiedliche Steigungen aufweisen, so daß sich bei gleicher Anzahl der Umdrehungen unterschiedliche Verschiebungen der Ventilspindel 30 und des Ventilkegels 42 ergeben. Die lose in die Mehrkant-Ausnehmungen 36 und 40 der Ventilspindel 30 und des Ventilkegels 42 eingesetzte Verbindungsstange 38 gestattet unterschiedliche Verschiebebewegungen der Ventilspindel 30 in Bezug auf den Ventilkegel 42. Der Ventilkegel 42 ist zweiteilig ausgeführt, wobei der äußere Teil 42' das Gewinde 44 aufweist und ein innerer Teil 42" den eigentlichen Kegel aufweist und gegen die Kraft einer Feder 51 in dem äußeren Teil 42' verschiebbar ist, um in bekannter Weise einen Rückflußverhinderer zu bilden.The threads 32 , 34 and 44 , 46 can have different pitches, so that different displacements of the valve spindle 30 and the valve cone 42 result with the same number of revolutions. The connecting rod 38 , which is loosely inserted into the polygonal recesses 36 and 40 of the valve spindle 30 and the valve cone 42 , permits different displacement movements of the valve spindle 30 with respect to the valve cone 42 . The valve cone 42 is designed in two parts, the outer part 42 'having the thread 44 and an inner part 42 "having the actual cone and being displaceable against the force of a spring 51 in the outer part 42 ' in order to provide a backflow preventer form.

Eine Rosette 52 ist auf das Außengehäuse 20 aufschraubbar und liegt mit einem Flansch 54 unter Zwischenfügung einer Flachdichtung 56 an der Außenwand 16 an, wodurch die Verbindung 24, 26 zwischen Innen- und Außengehäuse abgedeckt wird.A rosette 52 can be screwed onto the outer housing 20 and rests with a flange 54 with the interposition of a flat gasket 56 on the outer wall 16 , as a result of which the connection 24 , 26 between the inner and outer housing is covered.

Die Ventilspindel 30 wird durch ein Handrad 60 in Drehung versetzt, das auf die abgedichtet aus dem Außengehäuse 20 herausgeführte Ventilspindel 30 aufgesteckt ist. Der Hohlraum 28 ist mit einer Wasser-Entnahmestelle verbunden, die eine Rohrbelüftung 70 und eine Schlauchverschraubung 72 umfaßt. Ein Belüfter 62 besteht aus einem in das Außengehäuse 20 eingesetzten Stopfen 64, der gegen die Außenluft nicht abdichtet und einem Teller 68, der mit einer O-Ring-Dichtung 66 bei vorhandenem Wasserdruck an einer Schulter im Außengehäuse 20 zur Anlage gelangt und abdichtet; ansonsten aber eine Belüftung gestattet.The valve spindle 30 is set in rotation by a handwheel 60 which is attached to the valve spindle 30, which is sealed out of the outer housing 20 . The cavity 28 is connected to a water extraction point, which comprises a pipe ventilation 70 and a hose screw connection 72 . An aerator 62 consists of a plug 64 inserted into the outer housing 20 , which does not seal against the outside air, and a plate 68 , which comes into contact with an O-ring seal 66 with water pressure on a shoulder in the outer housing 20 and seals; otherwise ventilation is permitted.
