Abstract

The closure element (2) is a conical plug rotatably mounted transversely to the flow direction in the lower part of the valve passage (5). The conical plug has a section (4) machined out to corresp. to the cross-sectional shape of the pipeline and hence does not constrict the flow cross-section.The conical plug has a sealed mounting in a plastic bush and can be machined to corresp. to the valve cross-section. A piston jet can be used instead of a specimen bottle to ensure specimen extraction with no dead vol.

Description

Das Ventil zur Probeentnahme von Flüssigkeiten aus einer Rohrleitung ist hauptsächlich für eine Probeentnahme in Laborflaschen vorgesehen.The valve for sampling liquids from a Pipeline is mainly for sampling in Laboratory bottles provided.

Bisher bekannte Probeentnahmeventile dieser Art haben als Verschluß einen Dichtkegel, welcher zum Öffnen der Entnahme­ bohrung aus dem Kegelsitz herausgezogen wird.So far known sampling valves of this type have Closure a sealing cone, which is used to open the removal hole is pulled out of the cone seat.

Dieses hat den Nachteil, daß beim Schließen der Öffnung im Produkt befindliche Feststoffe sich zwischen Dichtkegel und Dichtkegelsitz festsetzen und somit die Dichtheit des Verschlusses beeinträchtigen können.This has the disadvantage that when the opening is closed Solids in the product are between the sealing cone and sealing cone seat and thus the tightness of the Can affect closure.

Außerdem wird die Dichtkegelstange durch die Durchflußöff­ nung des Ventiles geführt zwecks Betätigung des Verschlusses. Dieses wiederum hat den Nachteil, daß kein freier Rohrlei­ tungsquerschnitt vorhanden ist und somit bei molchbaren Rohrleitungen nicht eingesetzt werden kann.In addition, the sealing plug stem is through the flow opening Valve led out to actuate the closure. This in turn has the disadvantage that there is no free pipe cross-section is available and thus with piggable Pipelines cannot be used.

Die Erfindung weist diese Nachteile nicht auf und wird nachstehend anhand von vier Zeichnungen näher beschrieben. The invention does not and does not have these disadvantages described below with reference to four drawings.

Fig. 4 Längsschnitt des Ventiles zur Probeentnahme von Flüssigkeiten über Injektionsnadeln. Fig. 4 longitudinal section of the valve for sampling liquids via injection needles.

Das Ventil zur Probeentnahme von Flüssigkeiten aus Rohrlei­ tungen besteht aus einem Ventilgehäuse (1) und einem Ver­ schlußelement (2) welches drehbar gelagert in einer Kunst­ stoffbuchse (3) angeordnet ist und eine Ausarbeitung (4) aufweist, die im geschlossenen Zustand der Form des Durch­ lasses (5) angepaßt ist. Unter dem Verschlußelement (2) ist eine Öffnung (6) im Gehäuse angebracht, welche bei einer Drehung des Verschlußelementes (2) einen Durchfluß (7) zu der in einer Vorrichtung (8) eingesetzten Flasche (9) freigibt.The valve for sampling liquids from pipelines consists of a valve housing ( 1 ) and a United closure element ( 2 ) which is rotatably mounted in a plastic bushing ( 3 ) and has a draft ( 4 ) which, in the closed state, the shape of the By lasses ( 5 ) is adjusted. Under the closure element ( 2 ) there is an opening ( 6 ) in the housing which, when the closure element ( 2 ) rotates, releases a flow ( 7 ) to the bottle ( 9 ) used in a device ( 8 ).

Eine zweite Bohrung (10) dient zur Entlüftung der Flasche.A second hole ( 10 ) is used to vent the bottle.

Claims (5)

1. Ventil zur Probeentnahme von Flüssigkeiten aus Rohr­ leitungen, dadurch gekennzeichnet, daß das Verschluß­ element ein Kegelküken ist und quer zur Durchflußrich­ tung am unteren Teil des Durchganges des Ventiles dreh­ bar angeordnet ist.1. Valve for sampling liquids from pipes, characterized in that the closure element is a plug and is arranged transversely to the flow direction at the lower part of the passage of the valve rotating bar. 2. Ventil nach Anspruch 1, dadurch gekennzeichnet, daß das Kegelküken entsprechend der Querschnittsform der Rohrleitung ausgearbeitet ist und somit den Leitungs­ querschnitt nicht verengt.2. Valve according to claim 1, characterized in that the cone plug according to the cross-sectional shape of the Pipeline is worked out and thus the pipeline cross-section not narrowed. 3. Ventil nach Anspruch 1, dadurch gekennzeichnet, daß das Kegelküken in einer Kunststoffbuchse dichtend ge­ lagert ist und ebenfalls ausgearbeitet ist entsprechend der Querschnittsform des Ventiles.3. Valve according to claim 1, characterized in that sealing the cone plug in a plastic bushing is stored and also worked out accordingly the cross-sectional shape of the valve. 4. Ventil nach Anspruch 1, dadurch gekennzeichnet, daß anstelle der Probeflasche eine Kolbenspritze angebracht werden kann, wobei die Öffnung der Kolbenspritze formschlüssig gegen das Kegelküken gedrückt wird, so daß eine totraumfreie Probeentnahme gewährleistet ist.4. Valve according to claim 1, characterized in that A plunger syringe is attached instead of the sample bottle can be, opening the plunger syringe is positively pressed against the cone plug so that a dead space-free sampling is guaranteed is. 5. Ventil nach Anspruch 1, dadurch gekennzeichnet, daß der Hebel zur Auf-Zu-Stellung des Verschlußelementes als Totmannhebel ausgeführt ist.5. Valve according to claim 1, characterized in that the lever for the open-closed position of the closure element is designed as a dead man's lever.
