Abstract

The water outlet tap has a screw valve. A sealing washer made from flexible material is placed on the closure element and can oscillate for noise suppression against a hollow cavity. The clamping method of the washer ensures good sealing effect and long life for the washer. The cavity (9) behind the sealing washer (7) is connected by channels (10) in the valve closure element (3) with the low pressure chamber (11) of the valve. The valve closure element (3) is actuated normally by a screw spindle (6) in a valve upper part (5) by moving it into the housing (4) against the valve seat (2). The cavity (9) behind the washer is readily filled with water which is pushed back and forth due to the oscillating movement for damping purposes.

Wasserauslaufarmatur mit einem NiederschraubventilWater outlet fitting with a screw-down valve

Die Erfindung bezieht sich auf eine Wasserauslaufarmatur mit einem Niederschraubventil, in dessen Ventilschließkörper eine Dichtungsscheibe aus einem elastisch nachgiebigen Werkstoff eingesetzt ist, die gegen einen hinter ihr ausgesparten Hohlraum geräuschdämpfend ausschwingen kann.The invention relates to a water outlet fitting with a screw-down valve, in the valve closing body of which a Sealing washer made of an elastically resilient material is used against a cavity recessed behind it can swing out noise-dampening.

Im Ventilspalt treten im Hörbereich liegende Schallschwingungen auf, die die membranartig wirkende Dichtungsscheibe zum Mitschwingen anregen und auf ein hinter ihr in dem Hohlraum befindliches Luftpolster übertragen werden.Sound vibrations in the audible area occur in the valve gap, which the diaphragm-like sealing washer causes to resonate stimulate and be transferred to an air cushion located behind her in the cavity.

Da die Dichtungsscheibe, um schwingen zu können, nur an ihrem Außenrand eingespannt, z.B. in den Ventilschließkörper eingebördelt oder eingeklebt sein darf, besteht die Gefahr, daß mit der Zeit die hinter ihr befindliche Luft durch Undichtigkeit zwischen der Dichtungsscheibe und dem sie einfassenden Randteil des Ventilschließkörpers in den Niederdruckraum entweicht und allmählich durch überSince the sealing washer, in order to be able to vibrate, only on hers Clamped on the outer edge, e.g. crimped or glued into the valve closing body, there is a risk that over time the air behind it due to a leak between the sealing washer and the edge part of the valve closing body that surrounds it escapes into the low pressure chamber and gradually through over

die gleiche Undichtheit eindringendes Wasser ersetzt wird. Dann wird der Hohlraum hinter der Dichtungsscheibe, da er kein kompressibles Medium mehr enthält, schalltechnisch wirkungslos.the same leakage is replaced by penetrating water. Then the cavity is behind the sealing washer as it is not compressible Medium contains more, acoustically ineffective.

Aufgabe der Erfindung ist es, diesen Nachteil zu beseitigen. Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Hohlraum hinter der Dichtungsscheibe durch Bohrungen im Ventilschließkörper mit dem Niederdruckraum der Armatur verbunden ist. Nunmehr ist es schalltechnisch einerlei, ob der Hohlraum hinter der Dichtungsscheibe mit Luft oder Wasser gefüllt ist. Wenn die Dichtungsscheibe schwingt, wird eben Wasser aus dem hinter ihr befindlichen Hohlraum ausgeschoben und in ihn eingesaugt.The object of the invention is to eliminate this disadvantage. These The object is achieved according to the invention in that the cavity behind the sealing washer is formed by bores in the valve closing body is connected to the low pressure chamber of the valve. From a sound point of view, it is now irrelevant whether the cavity behind the sealing washer is filled with air or water. When the sealing washer vibrates, water is released from the cavity behind it pushed out and sucked into him.

In den Ventilschließkörper 3 ist eine dem Ventilsitz 2 gegenüberliegende Dichtungsscheibe 7 aus einem elastisch nachgiebigen Werkstoff, z.B. Gummi, eingesetzt, die an ihrem Außenrand in einem zylindrischen Randteil 8 des Ventilschließkörpers gefaßt, z.B. eingebördelt oder eingeklebt ist. Hinter der Dichtungsscheibe 7 ist in dem Ventilschließkörper 3 ein Hohlraum 9 ausgespart, der durch Bohrungen 10 mit dem Niederdruck- bzw. Abflußraum 11 des Ventilgehäuses verbunden ist. Auf diese Weise kann sich der Hohlraum 9 mit Wasser füllen. Die Dichtungsscheibe kann trotzdem geräuschdämpfend schwingen, weil sie durch die Bohrungen 10 des Ventilschließkörpers 3 zwischen dem Hohlraum 9 und dem Niederdruckraum 11 des Ventilgehäuses Wasser hin- und herschieben kann.In the valve closing body 3 is a valve seat 2 opposite Sealing washer 7 made of an elastically resilient material, e.g. rubber, used, which on its outer edge in a cylindrical Edge part 8 of the valve closing body is grasped, e.g. crimped or glued. Behind the sealing washer 7 is in the valve closing body 3 a cavity 9 is cut out, which is connected by bores 10 to the low-pressure or drainage chamber 11 of the valve housing. In this way, the cavity 9 can fill with water. The sealing washer can still vibrate in a noise-absorbing manner because they through the bores 10 of the valve closing body 3 between the Cavity 9 and the low pressure chamber 11 of the valve housing can push water back and forth.
