Verfahren zur Herstellung von Ventilen und Hähnen.
Die Erfindung betrifft eine Ausführungsform für Hähne und Ventile aller Art'mittels des Spritz-oder Pressgussverfahrens hergestellt,-durch welche die Nachteile bei Verwendung von Ersatzmetallen wie Zink-und Aluminiumlegierungen und Eisen vermieden werden. Die Nachteile der Ersatzmaterialien für Rot-und Gelbguss sind bekannt. Eisen rostet Zink-oder Aluminiumlegierung nutzt sich an den beanspruchten Bestandteilen rasch ab, Zinklegierung wird von Wasser und Dampf angegriffen und zersetzt, was namentlich an den Dichtungflächen sehr nachteilig wirkt. Durch die Sprödigkeit der Zinklegierung entsteht schon bei Herstellung und Montage ein grösserer Prozentsatz Abfall, welcher die Billigkeit und Verwendbarkeit aus solchen Materialien hergestellter Hähne und'Ventile in Frage stellt.
Die Erfindung besteht darin, die Gehäuseteile zwar aus einer spritzgussfähigen Legierung herzustellen, dagegen die Gewindezapfen oder Gewindebohrungen, die den Gebrauch ausgesetzt oder durch das An-und Abschrauben, usw., also durch die Montage gefährdet sind, aus-einem harten widerstandsfähigem Metall, beispielsweise aus Messing oder Eisen, herzustellen, welche Bestandteile der Erfindung gemäss in genau zentrischer Lage zur Hahnoder Ventilbohrung während der Spritzgussoperation gleich in die Gehäuseteile eingegossen werden.
Die Zeichnung zeigt als Ausführungsbeispiele in Fige I einen Auslaufhahn für Wasserleitungen, in Fig. 2 einen Kükenhahn im Längsschnitt, Die im Querschnitt gleichartigen Kernöffnungen a und b des Spritzgussgehäuses schliessen an die nur wenig grössere Gehäusebohrung c an und sind entsprechend gegeneinander versetzt.

Process for the manufacture of valves and taps.
The invention relates to an embodiment for taps and valves of all kinds produced by means of the injection or pressure casting process, by means of which the disadvantages of using substitute metals such as zinc and aluminum alloys and iron are avoided. The disadvantages of substitute materials for red and brass are known. Iron rusts Zinc or aluminum alloy wears off quickly on the stressed components, zinc alloy is attacked and decomposed by water and steam, which has a particularly disadvantageous effect on the sealing surfaces. As a result of the brittleness of the zinc alloy, a large percentage of waste is generated during manufacture and assembly, which calls into question the cheapness and usability of taps and valves made from such materials.
The invention consists in producing the housing parts from an injection-mouldable alloy, while the threaded pins or threaded bores, which are exposed to use or are endangered by screwing and unscrewing, etc., i.e. from assembly, from a hard, resistant metal, for example made of brass or iron, which components of the invention are poured into the housing parts in an exactly central position to the tap or valve bore during the injection molding operation.
The drawing shows as exemplary embodiments in Fig. I a drain cock for water pipes, in Fig. 2 a plug cock in longitudinal section, the cross-section similar core openings a and b of the injection molded housing adjoin the only slightly larger housing bore c and are accordingly offset from one another.
The spindle nut e, the valve seat f, the cock chuck g and on the cock. the rooster-

made of brass or the like, possibly also made of galvanized iron, and are smooth, with projections, with ribs or with thread, cast into the housing made of injection-mouldable alloy.
