Description

Die Erfindung betrifft ein Ablaufventil für Meß-oder Prüfzylinder oder ähnliche Gefäße, dessen Ventil'körper beim Aufsetzen auf das zu füllende Gefäß angehoben wird. The invention relates to a drain valve for measuring or test cylinders or similar vessels, the valve body of which when placed on the vessel to be filled is raised.

Die bekannten Ablaufventile, bei denen der Ventilkörper beim Aufsetzen auf das zu füllende Gefäß angehoben wird, so daß die in dem mit dem Ventil versehenen Behälter befindliche Flüssigkeit auslaufen kann, haben den Nachteil, daß die auslaufende Flüssigkeit mangels geeigneter Führung verspritzen kann, ehe der Meß- oder Prüfzylinder sich voll auf das zu füllende Gefäß aufgesetzt hat. The known drain valves, in which the valve body when put on is raised on the vessel to be filled, so that the in the provided with the valve Container located liquid can leak, have the disadvantage that the leaking In the absence of suitable guidance, liquid can splash before the measuring or test cylinder has fully sat down on the vessel to be filled.

Dadurch kann es vorkommen, daß genau gemessene Flüssigkeitsmengen, z. B. Reagenzien, an Menge verlieren, wodurch die Genauigkeit der Meßreaktion leidet.As a result, it can happen that precisely measured amounts of liquid, z. B. reagents lose in amount, whereby the accuracy of the measurement reaction suffers.

Um diesen Mängeln zu begegnen, wird gemäß -Erfindung vorgeschlagen, daß der Ventil schaft mit einem Auffanggefäß verbunden ist, aus dem die ausströmende Flüssigkeit in geregeltem Flusse abläuft. In order to counteract these deficiencies, it is proposed according to the invention, that the valve shaft is connected to a collecting vessel from which the outflow Liquid runs off in a regulated flow.

Vorzugsweise hat das Auffanggefäß die Gestalt eines Trichters. an dessen Bodenrand schräg nach außen mündende Öffnungen vorgesehen sind. Das Auffanggefäß kann ferner an seinem unteren Ende einen Stutzen aufweisen, dessen Durchmesser vorzugssveise der lichten LIündungslveite des zu füllenden Gefäßes entspricht und an dessen Außenfläche die Auslaßöffnuiigen münden. Zwischen den Auslaßöffnungen können Abfiachungen am Stutzen vorgesehen sein, damit die Luft aus dem zu füllenden Gefäß besser entlveichen kann. The collecting vessel preferably has the shape of a funnel. at the bottom edge of which openings are provided which open at an angle to the outside. The collecting vessel can also have a connecting piece at its lower end, the diameter of which is preferably corresponds to the clear opening width of the vessel to be filled and on its outer surface the outlet openings open. Flattened areas can be located between the outlet openings Nozzles can be provided so that the air can better escape from the vessel to be filled can.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht. The invention is illustrated by way of example in the drawing.

Fig. I zeigt einen Längsschnitt durch das Ablaufventil gemäß Erfindung in der Verschlußstellung; Fig. 2 zeigt das Ablaufventil in gleicher Darstellungsweise wie Fig. I, jedoch in Öffnungsstellung; Fig 3 zeigt das Auffanggefäß von unten gesehen und in Seitenansicht. Fig. I shows a longitudinal section through the drain valve according to the invention in the closed position; Fig. 2 shows the drain valve in the same way of representation like FIG. I, but in the open position; 3 shows the collecting vessel seen from below and in side view.

Der Meß- oder Prüfzylinder I, wie er beispielsweise bei Geräten zur AIilchuntersuchung zur Abmessung von Reagenzien Verwendung finden kann, ist an seinem unteren Ende durch ein Ablaufventil verschlossen. welches aus einem kugel- oder kegelförmigen Ventilkörper 2 besteht, das die Ablauföffnung 3 verschließt, solange der Meß- oder Prüfzylinder I mit dem Reagens gefüllt wird. The measuring or test cylinder I, as it is, for example, in devices for Milk analysis can be used to measure reagents is at his closed lower end by a drain valve. which consists of a spherical or conical valve body 2, which closes the drain opening 3, as long as the measuring or test cylinder I is filled with the reagent.

Der Ventilschaft 4 trägt an seinem unteren Ende ein Auffanggefäß 5, welches innen, dem unteren Ende des Zylinders I benachbart, die Gestalt eines Trichters 6 hat. Das Auffanggefäß 5 läuft in einen Stutzen 7 aus, dessen Durchmesser vorzugsweise der lichten Weite a des zu füllenden GefäBes 8 angepaßt ist, derart, daß Ider Stutzen 7 leicht in die Mündung des Gefäßes 8 eingeführt werden kann. The valve stem 4 carries a collecting vessel at its lower end 5, which inside, adjacent to the lower end of the cylinder I, has the shape of a Has funnel 6. The collecting vessel 5 runs out into a nozzle 7, the diameter of which is preferably adapted to the clear width a of the vessel 8 to be filled, in such a way that that Ider nozzle 7 can be easily inserted into the mouth of the vessel 8.

Am Boden des Trichters 6 sind AuslaBöffnungen 9 vorgesehen, die schräg nach außen an der Außenfläche des Stutzens 7 münden. Zwischen den Auslaßöffnungen g befinden sich Axbflachungen IO, welche die im Behälter 8 befindliche Luft entweichen lassen, wenn Flüssigkeit eingefüllt wird. At the bottom of the funnel 6 there are outlet openings 9 which are inclined open outwards on the outer surface of the connecting piece 7. Between the outlet openings g are Axbflachungen IO, which the air in the container 8 escape leave when liquid is added.

Aus Fig. 2 ist ersichtlich, daß, wenn der Ventilkörper 2 beim Aufsetzen des Auffanggefäßes 5 auf den Mündungsrand II des Gefäßes sich hebt, die aus dem Gefäß I ausfließende Flüssigkeit sich zunächst im Trichter 6 fängt und von dort über die Öffnungen- g in geregeltem Flusse an dieWandungen des Gefäßes 8 gelangt, au denen sie in das Innere des Gefäßes 8 herunterrinnt, ohne daß auch nur unwesentliche Teilchen der Flüssigkeit verspritzen können. Dadurch wird die Handhabung sauberer und die Abmessung genauer als bei den bisher bekannten Abl;aufventilen. From Fig. 2 it can be seen that when the valve body 2 when placed of the collecting vessel 5 on the mouth rim II of the vessel is raised from the Vessel I outflowing liquid is first caught in the funnel 6 and from there reaches the walls of the vessel 8 via the openings g in a controlled flow, au which it runs down into the interior of the vessel 8, without even insignificant Particles of the liquid can splash. This makes handling cleaner and the dimensions more precisely than with the previously known drain valves.
