Description
Es ist bekannt, Ventilgehäuse aus geformten Blechstücken, die durch Schweißnähte miteinander verbunden sind, herzustellen. Hierdurch erhält man Ventilgehäuse, die die in dieser Art der Herstellung beruhenden bekannten Vorteile aufweisen. Die so hergestellten Ventilgehäuse haben aber · den Nachteil, daß sie leicht Fonnabänderungen, die Undichtheiten im Gehäuse oder auch ein schlechtes Aufsitzen des Ventilkörpers auf dem Sitz im Gefolge haben, unterworfen und nicht genügend widerstandsfähig gegen höhere, Drücke sind.It is known, valve housing made of shaped sheet metal pieces, which are welded together connected to produce. This gives valve housings that are known to those based on this type of manufacture Have advantages. The valve housings produced in this way have the disadvantage that they easily change the shape, the leaks in the housing or even a bad one Seating of the valve body on the seat in the wake have been subjected and insufficient are resistant to higher pressures.
Gemäß der Erfindung sollen die erwähnten Nachteile dadurch beseitigt werden, daß das Ventilgehäuse aus vier oder mehreren Blechstücken zusammengesetzt ist, die in der lot-" rechten Mittellängsschnittebene des Gehäuses und mit dem den Ventilsitz tragenden Zwischenboden und den Gehäuseflanschen derart verschweißt sind, daß die in senkrecht zueinander verlaufenden Flächen liegenden Schweißnähte sich jeweils in zwei Punkten berühren. Dazu hat die neue Herstellungsweise die Vorteile, daß die Schweißnähte vollständig außen auf dem Ventilkörper liegen und so geprüft und durch Hämmern und Feilen nachbearbeitet werden können. Dabei entspricht die Gestaltung des neuen Ventilgehäuses der Form der bekannten gegossenen Ventilgehäuse. In der Zeichnung ist in mehreren Ausführungsbeispielen der Erfindungsgegenstand dargestellt. According to the invention, the disadvantages mentioned are to be eliminated in that the Valve housing is composed of four or more pieces of sheet metal, which are in the solder " right central longitudinal sectional plane of the housing and with the intermediate floor supporting the valve seat and the housing flanges are welded in such a way that they are perpendicular to one another The weld seams lying on the running surfaces touch each other at two points. In addition the new manufacturing method has the advantage that the welds are completely on the outside the valve body and so checked and reworked by hammering and filing can be. The design of the new valve housing corresponds to the shape the well-known cast valve body. The drawing shows several exemplary embodiments the subject matter of the invention presented.
Die Abb. 1 zeigt ein Ventil in Ansicht und zum Teil im Schnitt.Fig. 1 shows a valve in view and partly in section.
Abb. 2 stellt in perspektivischer Ansicht einen einzelnen Teil dar, bevor er mit den anderen Teilen des Gehäuses zur Bildung des Ventils verschweißt wird.Fig. 2 is a perspective view of a single part before it goes with the other parts of the housing is welded to form the valve.
Abb. 3 zeigt in Außenansicht und teilweisem Längsschnitt ein Ventil in anderer Ausführungsform. Fig. 3 shows an external view and a partial longitudinal section of a valve in a different embodiment.
Abb. 4 ist ein Querschnitt nach Linie IV-IV der Abb. 3.Fig. 4 is a cross section along line IV-IV of Fig. 3.
Die Abb. 5 und 6 zeigen in Außenansicht und in einem axialen Schnitt zwei andere Ventilformen, die gemäß der Erfindung hergestellt sind.Figs. 5 and 6 show two others in an external view and in an axial section Valve molds made in accordance with the invention.
Bei' allen dargestellten Ausführungen sind die Ventilgehäuse aus einzelnen geformten Blechstücken hergestellt, die miteinander durch Schweißnähte verbunden sind. Eine der Schweißnähte liegt in der Symmetrieebene des Ventilgehäuses und ist in allen Abbildungen mit ι bezeichnet.In all of the designs shown, the valve housings are molded from individual pieces Sheet metal pieces produced, which are connected to each other by welds. One of the The weld seam lies in the plane of symmetry of the valve housing and is shown in all figures denoted by ι.
Eine andere Schweißnaht verläuft längs dem Umfang des Zwischenbodens 7, in den der Sitz des Ventils eingesetzt ist. Die Fläche des Zwischenbodens 7 steht senkrecht zur Symmetrieebene des Ventilgehäuses, so daß auch die längs des Umfanges des Zwischenbodens befindliche Schweißnaht, die den Zwischenboden mit den Blechstücken verbindet, in einer senkrecht zur Symmetrieebene des Ventilgehäuses stehenden Fläche liegt. An den rohrartigen Enden des so geschaffenen Gehäuses sind Flansche 2, 2', 2" angebracht, die durch Schweißung mit dem Gehäuse verbunden sind. Jede der Schweißnähte 9, 10, 11 befindet sich in einer Ebene, die senkrecht zur Symmetrieebene des Gehäuses steht und folglich auch zu der darin enthaltenen Schweißnaht 1. Wie aus den Zeichnungen zu ersehen, berührt jede Schweißnaht in zwei Punkten eine andere Schweißnaht. Hiernach bilden die Schweißnähte einen Versteifungs- und Verstärkungskäfig für das Ventilgehäuse.Another weld seam runs along the circumference of the intermediate floor 7 in which the seat of the valve is inserted. The surface of the intermediate floor 7 is perpendicular to the plane of symmetry of the valve housing, so that the located along the circumference of the false floor Weld seam that connects the intermediate floor with the sheet metal pieces, in a vertical to the plane of symmetry of the valve housing standing surface. On the tube-like Ends of the housing created in this way are flanges 2, 2 ', 2 "attached by welding are connected to the housing. Each of the welds 9, 10, 11 is located in a plane which is perpendicular to the plane of symmetry of the housing and consequently also to the weld seam contained therein 1. As can be seen from the drawings, each touches Another weld seam at two points. After that form the welds a stiffening and reinforcing cage for the valve housing.
