Abstract

The valve has two independent plates, the top one moving through the leak-monitoring chamber to strike the bottom one and lift it clear of its seat. There are two or more passages connected to the chamber, both of which can be shut by controlled valves. Cleaning material is introduced through one passage, and leaves the chamber via a monitoring passage. This passage remains open when the main valve is shut. The valve is particularly for handling foodstuffs, and when open the material handled can in no way escape to atmosphere etc.

Doppelsitzventil mit LeckkontrollraumDouble seat valve with leak control room

Doppelsitzventile mit Leckkontrollraum sind bekannt z.B. in der Auslegeschrift 2 001 599· Zwischen zwei.Ventiltellern befindet sich ein Leckkontrollraum mit einer öffnung ins Freie. Wenn einer der Ventilteller undicht ist, gelangt die Leckflüssigkeit nach außen und ist somit die Undichtigkeit erkennbar.Double seat valves with a leak control chamber are known, for example, from Auslegeschrift 2 001 599 Between two valve disks there is a leak control room with an opening to the outside. If one of the valve plates is leaking, gets the leakage fluid to the outside and thus the leak can be identified.

Der Nachteil bei einem solchen Doppelsitzventil ist der, daß bei jedem Schaltvorgang Flüssigkeit nach außen gelangt, weil der obere Ventilteller einen bestimmten Weg zurücklegen muß, ehe er sich auf den unteren Ventilteller setzt, um den VentilVerschluß aufzuheben. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, mit einem oberen Ventilteller einen unteren Ventilteller zu öffnen, aber so, daß in dem Moment des Öffnungsvorganges der Leckkontrollraum geschlossen ist. Der Vorteil in dieser Erfindung liegt darin, daß der Leckkontrollraum in geschlossener Stellung des. Doppelsitzventils eine öffnung ins Freie aufweist, daß diese öffnung aber vor Betätigung der Teller im Gegensatz zu der Auslegeschrift 260I 599 geschlossen wird und dasThe disadvantage of such a double seat valve is that with every switching operation liquid escapes, because the upper valve disk has to cover a certain distance before it sits on the lower valve disk, to unlock the valve. The present invention is based on the task of opening a lower valve disc with an upper valve disc, but in such a way that at the moment of opening the leak control room is closed. The advantage in this invention is that that the leak control chamber has an opening to the outside in the closed position of the double seat valve, that However, this opening is closed before actuation of the plate, in contrast to the Auslegeschrift 260I 599 and that

Förderprodukt nirgends austreten kann. Das Wesentliche bei Nahrungsmxttelventxlen ist die Reinigungsmöglichkeit des Leckkontrollraumes und daher hat erfindungsgemäß dieses Doppelsitzventil zwei Anschlüsse, und zwar ein verschließbares Reinigungsrohr und eine verschließbare öffnung ins Freie. Bei der Hubbewegung sind beide Anschlüsse geschlossen. In der beiliegenden Zeichnung ist eine Ausführungsform veranschaulicht. Im Ventilgehäuse mit seinem Zuflußgehäuseteil 2 und seinem Abflußgehäuseteil 3 eines Doppelsitzventils gemäß der Erfindung, befindet sich eine Sitzfläche 4, die den oberen Ventilteller 5 mit einer Ventilspindel 10 und .den unteren Ventilteller 6 mit einer Sitzfläche 4 a in Schließstellung des Ventils aufnimmt. Zwischen den Ventiltellern 5 und 6 befindet sich ein Leckkontrollraum 7· Dieser Leckkontrollraum 7 hat eine Kontrollbohrung 19 , die ins Freie mündet. Diese Kontrollbohrung 19 beim Abwärtsgang des oberen Ventiltellers 5, der sich zur Weiteröffnung auf den unteren Ventilteller 6 mit seiner Ventilspindel 8 der unteren Feder 14 und dem Bund 13 legt, wird durch den Ventilteller 20 mit der Ventilspindel 21 und der Ventilfeder 22 geschlossen. In den Leckkontrollraum 7 führt das Reinigungsrohr 15» das durch den Ventilteller l6 mit der Ventilspindel 17 und der Ventilfeder 18 absperrbar ist. Bei geschlossenem Ventil ist an der Kontrollbohrung zu erkennen, ob die Ventilsitze 4 und 4 a dicht sind. Wird das Ventil gereinigt, so sind die Ventilteller 16 und vom Sitz herunter und die Reinigungsflüssigkeit strömt in das Reinigungsrohr 15, passiert den Leckkontrollraum 7, um bei der Kontrollbohrung 19 wieder auszutreten.The conveyed product cannot escape anywhere. The essential feature of food valves is the possibility of cleaning the leak control room and therefore, according to the invention, this double seat valve has two connections, namely a closable cleaning tube and a closable opening to the outside. Both connections are closed during the lifting movement. An embodiment is illustrated in the accompanying drawing. In the valve housing with its inflow housing part 2 and its outflow housing part 3 of a double seat valve according to the invention, there is a seat 4, which receives the upper valve disk 5 with a valve spindle 10 and .den lower valve disk 6 with a seat 4 a in the closed position of the valve. A leak control space 7 is located between the valve disks 5 and 6. This leak control space 7 has a control bore 19 which opens out into the open. This control bore 19 during the downward movement of the upper valve disk 5, which lies on the lower valve disk 6 with its valve spindle 8, the lower spring 14 and the collar 13 for further opening, is closed by the valve disk 20 with the valve spindle 21 and the valve spring 22. The cleaning tube 15, which can be shut off by the valve disk 16 with the valve spindle 17 and the valve spring 18, leads into the leak control chamber 7. When the valve is closed, the control hole shows whether the valve seats 4 and 4 a are tight. When the valve is cleaned, the valve disks 16 and 16 are removed from the seat and the cleaning fluid flows into the cleaning tube 15, passes through the leakage control space 7, in order to exit again at the control bore 19.
