Väkuumhahn.Vacuum cock.

Dia Erfindung bezieht Bich auf einen Hahn, insbesondere einen Hahn für Vakuum- oder Niederdruckgeräte und dergleichen.The invention relates to a tap, in particular a tap for vacuum or low pressure devices and the like.

Bei Hähnen dieser Art ist as bekannt, den Verschluss dadurch zu bewerkstelligen, dass ein Poleterglied gegen ein sogenanntes Messerechneideglied gedruckt wird, wobei das Polsterglied aus Kupfer öder öold besteht, aber diese Konstruktion hat den Kaohteil, dass naoh mehreren Abüclilieas vorgänge η der Vakuumverschluss unwirksam ist, weil das aus Kupfer öder Gold bestehende Polster flieset und sich unter dem Brück der Jfeiäsörschneide verformt»In taps of this type, it is known to close the valve to accomplish that a Poleter member against a so-called Knife cutting member is printed with the cushion member made of copper or Öold exists, but this construction has the kaoh part that naoh several Abüclilieas processes η the vacuum seal is ineffective because the padding, made of copper or gold, flows under the Jfeiäsörschneide bridge deformed »

Bin AuefUhrungebeispiel der Erfindung ist in der Zeichning. dargestellt und vird im folgenden naher beschrieben. In der Figur, die schematisch einen Schnitt durch den Verschluss darstellt, bezeichnet das Meeserschneideglied, während 2 ein Bolster ist, das, wenn es unter der Einwirkung eines mit Gewinde versehenen Gliedes 3, das mit einer nicht dargestellten feststehenden Hut zusamoenarbeitet, bewegt wird, gegen die Messerschneide 1 gedrückt werden kann, so dass sich ein Abschluss ergibt. Sin Federrohr 4 ist luftdicht mit dem Polster 2 verbunden und erlaubt eine gewisse Bewegung des Polsters, wahrend die Gasdrücke beiderseits des Polsters 2 verschieden sein können.A execution example of the invention is in the drawing. and is described in more detail below. In the figure that schematically represents a section through the closure, denotes the sea cutter while 2 is a bolster that when it is under the action of a threaded member 3 with a fixed hat, not shown, works together, is moved, can be pressed against the knife edge 1, so that there is a conclusion. Sin spring tube 4 is airtightly connected to cushion 2 and allows a certain movement of the cushion, while the gas pressures on both sides of the cushion 2 can be different.

Auf der Seite des Polsters 2, die der Messerschneide 1 zugekehrt ist, ist vorzugsweise auf galvanischem Wege eine dünne Ooldsohicht 5 angebracht. Das Polsterglied 2 kann aus rostfreiem Stahl bestehen, der erheblich harter als Gold ist und das erwähnte Abstützmaterial bildet. Die Messerschneide kann ebenfalls aus rostfreiem Stahl bestehen. Als rostfreier StaüL wird vorzugsweise ein in der britischen Forakode . bekanntes Material gewXhlt.On the side of the pad 2 facing the knife edge 1, there is a thin Ooldso layer, preferably by electroplating 5 attached. The cushion member 2 can consist of stainless steel, which is considerably harder than gold and forms the aforementioned support material. The knife edge can also be made of stainless steel. The preferred stainless steel stool is a in the British fora code. known material selected.

Die Messerschneide, die einen Schneidewinkel von etwa 60° aufweist, kann scharf sein oder einen sehr schmalen Rand einer Breite von etwa 0,1 bis 0,13 Millimeter aufweisen.The knife edge, which has a cutting angle of about 60 ° can be sharp or have a very narrow edge about 0.1 to 0.13 millimeters wide.

Bevor die Goldsohicht 5 angebracht wird, wird der rostfreie Teil galvanisch mit einer dünnen Nickelschioht versehen. Die Qoldechioht wird danach gleichfalls galvanisch aus einer Lösung von Goldcyanid, an die Kaliumthiocyanid hinzugefügt ist, niedergeschlagen; die Schichtstarke beträgt etwa 5 bis 10 Mikron.Before the gold layer 5 is attached, the stainless Part galvanically provided with a thin nickel layer. The Qoldechioht is then also electroplated from a solution of gold cyanide the potassium thiocyanide is added, precipitated; the layer thickness is about 5 to 10 microns.
