Absperrventil ir ünterputzVerlegungShut-off valve for flush-mounted installation
Die Erfindung betrifft ein Absperrventil für Unterputzverlegung, mit einem aus Kunststoff bestehenden Gehäuse, in dem ein metallisches Anschlußstück eingebaut ist, das mit einem Gewinde zum Einschrauben des Ventilabsperrorgans zur Steuerung des Ventildurchflusses versehen ist.The invention relates to a shut-off valve for concealed installation, with a plastic housing, in which a metallic connector is installed, which is provided with a thread for screwing in the valve shut-off device to control the valve flow.
Derartige Ventile werden in zunehmendem Maße bei der Verlegung von insbesondere aus Kunststoff bestehenden Wasserleitungsrohren eingesetzt, die selbst unter Putz bzw. im Mauerwerk von Decken und Wänden von Gebäuden verlegt werden.Such valves are increasingly used in the installation of water pipes, particularly those made of plastic, which are themselves installed under plaster or in the masonry of ceilings and walls of buildings.
Bei den bekannten Absperrventilen dieser Art besteht der Nachteil, daß an dem vom Kunststoff des Gehäuses umspritzten metallischen Anschlußstück besondere Vorkehrungen getroffen werden müssen, damit verhindert wird, daß sich dieses in Form einer mit einem Innengewinde versehenen Hülse ausgebildete Anschlußstück beim Ein- und Ausschrauben des Ventilabsperrorga.ns innerhalb des Kunststoffmantels mitdreht. Diese Vorkehrungen inThe known shut-off valves of this type have the disadvantage that special precautions must be taken on the metal connection piece that is molded into the plastic of the housing to prevent this connection piece, which is designed in the form of a sleeve with an internal thread, from rotating within the plastic casing when the valve shut-off device is screwed in and out. These precautions in

Form von oberflächlichen Schlitzen, Hohlräumen bzw. Durchbrüchen und Vertiefungen, in die das Kunststoffmaterial beim Spritzen eintreten kann, können vermieden werden, wenn gemäß dem ErfindungsVorschlag das metallene Anschlußstück Teil eines metallenen Vv i^-lkörpergehäuses ist, das insgesamt von dem Kunststoffgehäuse des Absperrventils umhüllt ist.Form of superficial slots, cavities or openings and depressions into which the plastic material can enter during injection molding can be avoided if, according to the invention proposal, the metal connection piece is part of a metal Vv i^-body housing, which is completely enclosed by the plastic housing of the shut-off valve.
Da das metallene Ventilkörpergehäuse in Durchf 1 .,ßrichtung des Ventils rohrfisrmige Verlängerungen aufweist, die dem Gehäuse eine in etwa T-förmige Form verleihen, wird das hülsenförmige Anschlußstück im Kunststoffgehäuse drehfest verankert, so daß zusätzliche Verankarungselemente auf der Oberfläche des Anschlußstückes entfallen können.Since the metal valve body housing has tubular extensions in the direction of flow of the valve, which give the housing an approximately T-shaped form, the sleeve-shaped connecting piece is anchored in the plastic housing in a rotationally fixed manner, so that additional anchoring elements on the surface of the connecting piece can be omitted.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung läßt sich der Gewindeausgang des Anschlußstückes zur Bildung einer zusätzlichen Abdichtung des Ventilabsperrorgans gegenüber dem Gehäuse mit dem Kunststoffmaterial, aus dem das Gehäuse besteht, überspritzen.According to an advantageous embodiment of the invention, the threaded outlet of the connecting piece can be overmolded with the plastic material from which the housing is made in order to form an additional seal between the valve shut-off device and the housing.
Die Erfindung wird nachfolgend anhand des in der Zeichnung dargestellten AusfUhrungsbeispiels, das eine Längsscnnittansicht des Absperrventils ohne Ventilabsperrorgan zeigt, näher erläutert.The invention is explained in more detail below using the embodiment shown in the drawing, which shows a longitudinal sectional view of the shut-off valve without a valve shut-off device.
Das Absperrventil für Unterputzverlegung besteht aus einem Gehäuse 1 aus Kunststoff und einem metallischen Anschlußstück 2 als Teil eines metallenen Ventilkörpergehäuses 7, das vollständig von dem Kunststoff 8 des Gehäuses 1 umhüllt ist, wobei die Umhüllung durch Umspritzen des metallenen Ventilkörpergehäuses erfolgt, welches im vorliegenden Fall aus Messing besteht.The shut-off valve for concealed installation consists of a housing 1 made of plastic and a metal connection piece 2 as part of a metal valve body housing 7, which is completely covered by the plastic 8 of the housing 1 , whereby the covering is carried out by overmolding the metal valve body housing, which in this case is made of brass.

In Durch f 1 uR ri c.-htunq 'les Ventils, die dur:h den (■ i.nqezeichneten Pfeil ^kennzeichnet .ist, weist das Kunststoffgehäuse des Absperrventils Muffen r>, G auf, nn die die Rohrleitungsabschnitte angeschlossen werden, in die das Ventil eingebaut wird. In diese Muffen erstrecken sich von dem metallenen Ventilkörpergehäuse hülsenartige Verlängerungen 9, 10, so daß das von dem Kunststoff üiüäpritzte VentiikörpergehSusc 7 in etwa T-Fcrm aufweist. Diese Konfiguration verhindert, daß sich das Anschlußstück 2, das mit einem Innengewinde 3 versehen ist, beim Ein- und Ausschrauben des nicht dargestellten Ventilabsperrorgans mitdreht. Somit stellen die hülsenförmigen Verlängerungen 9, 10 die Drehfestigkeit des Anschlußstücks 2 sicher.In the direction of the valve, which is indicated by the arrow marked ^, the plastic housing of the shut-off valve has sleeves r , G, to which the pipe sections into which the valve is installed are connected. Sleeve-like extensions 9, 10 extend from the metal valve body housing into these sleeves, so that the valve body housing 7 injected with the plastic has an approximately T-shape . This configuration prevents the connecting piece 2, which is provided with an internal thread 3, from rotating when the valve shut-off device (not shown) is screwed in and out. The sleeve-like extensions 9, 10 thus ensure the torsion resistance of the connecting piece 2.
Zur Verbesserung der Abdichtung des Absperrventils in bezug auf das in das Absperrventil einzuschraubende Ventilabsperrorgan ist der Ausgang 11 des Gewindes 3 mit dem Kunststoffmaterial des Gehäuses überspritzt, wie bei 4 dargestellt. Diese Uberspritzung bildet also eineTo improve the sealing of the shut-off valve in relation to the valve shut-off device to be screwed into the shut-off valve, the outlet 11 of the thread 3 is overmolded with the plastic material of the housing, as shown at 4. This overmold thus forms a
