Abstract

The advantage of this type of valve is that noise when the valve is in use is very much reduced. The opening in the valve seat when seen in plan has the profile of a three point polygon. The sides may be curved, at a large radius, with the points consisting of curves of small radius, and it can be positively located position using the appropriately shaped key. The sleeve is mfd. for all common pipe sizes. There is a chamfering on upper and lower sides of the seating sleeve on the edges of the polygon shaped opening. The valve plunger is shaped to fit into the sleeve.

Description

entilsitzvalve seat

Die Erfindung betrifft einen einschraubbaren, als Hülse ausgebildeten Ventilsitz für Sanitärarmaturen.The invention relates to a screwable, as a sleeve trained valve seat for sanitary fittings.

Bekannte einschraubbare Ventilsitze sind an der Durchgangsöffnung für die vfesserführung mit Innensechskant oder Innenrief enverzahnung ausgerüstet, in welche ein entsprechend geformter Schlüssel ansetzbar ist.Known screw-in valve seats are on the through opening for the vfesserführung with a hexagon socket or internal groove toothing, in which a correspondingly shaped key can be attached.

In neuerer Zeit werden immer höhere Anforderungen an Sanitärarmaturen in bezug auf Geräuscharmst gestellt. Die bekannten Einschrr.ubventilsitze zeigen ein ungünstiges Verhalten in bezug auf die Geräuschentwicklung, - .More and more demands on sanitary fittings have recently become in relation to low noise. The well-known screw-down valve seats show an unfavorable behavior in with regard to the noise development, -.

Aufgabe der Erfindung ist es, die genannten Nachteile der bekannten Einschraubventile zu vermeiden.The object of the invention is to avoid the disadvantages mentioned of the known screw-in valves.

Die Aufgabe wird erfindungsgemäß dndurch gelöst, daß der als Hülse ausgebildete Ventilsitz eine Durchgangsöffnung hat, deren Querschnitt ein Dreipunktpofygonprofil bildet.The object is achieved according to the invention in that the valve seat designed as a sleeve has a through opening, the cross section of which forms a three-point pofygon profile.

Durch diese Ausbildung wird einerseits erreicht, daß mit einem entsprechend geformten Schlüssel der Ventilsitz sicher fest eingeschraubt werden kann und andererseits, wie durchgeführte Versuche gezeigt haben, ein wesentlich günstigeres Geräuschverhalten erzielt wird.This design achieves on the one hand that the valve seat can be securely screwed in with a suitably shaped key and, on the other hand, as tests carried out have shown, a significantly more favorable noise behavior is achieved.

Ein praktisches Ausführungsbeispiel der Erfindung ist in der Zeichnung vergrößert dargestellt und wird im folgenden näher beschrieben.A practical embodiment of the invention is shown in FIG The drawing is shown enlarged and is described in more detail below.

Fig. 1 zeigt einen einschraubbaren Ventilsitz in Ansicht teilweise geschnitten; Fig. 2 zeigt den einschraubbaren Ventilsitz in Draufsicht.1 shows a screw-in valve seat in a partially sectioned view; Fig. 2 shows the screw-in valve seat in plan view.

Der Ventilsitz ist als Schraubhülse ausgebildet, an deren einen Seite ein Ansatz mit Gewinde 1 zum Einschrauben in ein Ventilgehäuse angeordnet ist. Die Durchgangsbohrung 2 ist als Dreipunktpolygonprofil ausgebildet und trägt oben und unten zur geräuscharmen An- und Ableitung der Flüssigkeit sowie zum sicheren Anführen des Schlüssels Anfasüngen 3 und 4,The valve seat is designed as a screw sleeve to which one side has a thread 1 approach for screwing into a valve housing. The through hole 2 is designed as a three-point polygon profile and contributes to the low-noise intake and discharge of the liquid at the top and bottom as well as to safely guide the key bevels 3 and 4,

Selbstverständlich ist das Dreipunktpolygonprofil für alle unterschiedlichen Durchtrit.tsquerschnitte, wie sie im Sanitärarmaturenfach gebräuchlich sind, anwendbar.Of course, the three-point polygon profile is for everyone different passage cross-sections, such as those in the sanitary fittings compartment are common, applicable.
