They are used, for example, on filter housings which are equipped with filter modules and are operated under a pressure difference
In vielen Bereichen, insbesondere bei der Filtration von Fluiden in der pharmazeutischen, biotechnologischen und lebensmitteltechnischen Industrie müssen Ventile verwendet werden, die folgenden Ansprüchen gerecht werden Gewahrleistung einer hohen Betriebssicherheit, wie Nusschluß der Möglichkeit einer Entfernung der Ventilnadel oder einer Unwirksamkeit der Dichtung des Ventils durch unsachgemäße Bedienung, Ausschluß von schwer zuganglichen Bereichen und von Totvolumina, die eine absolute Reinigung des Ventils oder eine Entfernung unerwünschter Medien verhindern, Gewahrleistung einer leichten Wartung, zum Beispiel zum Ersatz von Dichtungen durch unerfahrenes Personal, kostengünstige Herstellung Die Ventile des Standes der Technik werden diesen Ansprüchen nicht gerechtIn many areas, in particular in the filtration of fluids in the pharmaceutical, biotechnological and food technology industries, valves must be used which meet the following requirements. Ensuring high operational safety, such as the possibility of removal of the valve needle or ineffectiveness of the valve seal due to improper use Operation, exclusion of areas that are difficult to access and dead volumes that prevent absolute cleaning of the valve or removal of unwanted media, guarantee easy maintenance, for example for the replacement of seals by inexperienced personnel, cost-effective manufacture. The valves of the prior art meet these requirements not fair
Bei den bekannten Ventilen ist eine in einem Ventilgehause mit einem zylindrischen Ventilsitz befindliche hohle Ventilnadel aus Edelstahl mit einer Dichtung versehen Durch Drehen einer Überwurfmutter oder der Ventilnadel selbst wird die Dichtung auf eine Ventiloffnung gepreßt oder von ihr entfernt Die Dichtung besteht aus Gründen der hohen chemischen Resistenz aus Kunststoff, beispielsweise aus Polytetrafluorethylen Nachteilig ist, daß die Dichtung bei unsachgemäßem Schließen des Ventils in die Ventiloffnung hineingedruckt wird, was dazu fuhren kann, daß sich beim Offnen des Ventils die Dichtung von der Ventilnadel ablost und die Ventilöffnung verstopft oder das Ventil verklemmt, wodurch es unbrauchbar wird Zur Gewahrleistung der Dichtfunktion müssen die Dichtungen eine planare Oberflache aufweisen Daher muß die Dichtung, nachdem sie auf die Ventilnadel aufgesetz wurde, plan abgedreht werden Nachteilig ist, daß dazu entsprechende Werkzeuge und fachkundiges Personal erforderlich ist Die Dichtung kann zwar leicht ausgetauscht werden, jedoch verliert der Sitz der Dichtung im Betrieb schnell an Festigkeit, so daß die Funktion des Ventils beeinträchtigt ist Nachteilig ist auch, daß bei den Ventilen, deren Ventilnadel ganz aus dem Ventilsitz herausgedreht werden kann, ein Flussigkeits- oder Gasstrom in diesem Zustand nicht mehr kontrollierbar ist Das kann zur Kontamination der Umgebung und zu Verletzungen des Bedienerpersonals fuhren Bekannt ist das Verhindern des Herausziehens der Ventilnadel mittels einer Kette, die am Ventilgehause befestigt und über die Ventilnadel gelegt ist Allerdings stellt die Kette ein zusatzliches Bauelement dar, das schwer zu reinigen und damit für Arbeiten unter Reinraum- oder unter sterilen Bedingungen ungeeignet ist Nachteilig ist auch, daß ein im Inneren des Ventilgehauses liegendes Gewinde eine Ansammlung von Ecken und Kanten darstellt, die schwer zu reinigen sind und Kontaminationen der Fluide verursachen kannIn the known valves, a hollow valve needle made of stainless steel located in a valve housing with a cylindrical valve seat is provided with a seal. By rotating a union nut or the valve needle itself, the seal is pressed onto or removed from a valve opening. The seal is made for reasons of high chemical resistance made of plastic, for example polytetrafluoroethylene It is disadvantageous that the seal is pressed into the valve opening if the valve is improperly closed, which can lead to the fact that when the valve is opened The valve detaches the seal from the valve needle and closes the valve opening or jams the valve, rendering it unusable. To ensure the sealing function, the seals must have a planar surface. Therefore, the seal must be turned flat after it has been placed on the valve needle. that appropriate tools and skilled personnel are required for this purpose. The seal can be easily replaced, but the seat of the seal quickly loses strength during operation, so that the function of the valve is impaired. It is also disadvantageous that the valve needle has its valve needle completely out the valve seat can be unscrewed, a liquid or gas flow can no longer be controlled in this state.This can lead to contamination of the environment and injuries to the operating personnel. It is known to prevent the valve needle from being pulled out by means of a chain which is attached to the valve housing and above the valve needle is inserted However, the chain is an additional component that is difficult to clean and therefore unsuitable for work in clean room or under sterile conditions. It is also disadvantageous that a thread inside the valve housing represents a collection of corners and edges, which are difficult to clean and can cause contamination of the fluids
Der Erfindung liegt die Aufgabe zugrunde, ein Ventil für Flüssigkeiten und Gase bereit zu stellen, das eine hohe Betriebssicherheit, eine gute Reinigung und eine einfache Wartung gewahrleistetThe invention has for its object to provide a valve for liquids and gases, which ensures high operational reliability, good cleaning and easy maintenance
Die Aufgabe wird durch ein Ventil mit den Merkmalen des Anspruchs 1 gelost Vorteilhafte Ausgestaltungen des Ventils werden durch die Merkmale der abhangigen Ansprüche definiertThe object is achieved by a valve with the features of claim 1. Advantageous refinements of the valve are defined by the features of the dependent claims
Das erfindungsgemaße Ventil für Flüssigkeiten und Gase besteht mindestens aus einem Ventilgehause mit einem zylinderformigen Ventilsitz mit einer Durchgangsbohrung, über welche das Ventil mit einem Behalter kommunizierend verbindbar ist, und aus einer mit einem Kanal für die Flüssigkeiten und Gase und einer geschlossenen Spitze ausgestatteten Ventilnadel, die in dem Ventilgehause mit dem zylinderformigen Ventilsitz beweglich angeordnet ist derart, daß die Spitze mit Dichtung im geschlossenen Zustand des Ventils bis an die Durchgangsbohrung reicht Die Spitze der Ventilnadel besitzt ein Außenprofil, über welches sich die Dichtung, vorzugsweise aus Kunststoff, mit einem zu dem Außenprofil inversen Innenprofil befindet Dabei sind die Profile in der Art eines Schnappverschlusses ausgebildet Durch die erfindungsgemaße Ausbildung der Profile wird ein besonders fester Sitz der Dichtung auf der Spitze der Ventilnadel erreicht Selbst wenn die Ventilnadel unter Zuhilfenahme von Werkzeugen, wie Zangen oder Maulschlüsseln, beim Schließen des Ventils über Gebuhr festgezogen worden ist, kann sich die Dichtung zwar verformen, sie lost sich beim Offnen des Ventils aber nicht von der Spitze der Ventilnadel ab Damit bleibt die Betriebssicherheit des Ventils auch bei unsachgemäßer Handhabung erhaltenThe valve according to the invention for liquids and gases consists at least of a valve housing with a cylindrical valve seat with a through-hole, via which the valve can be communicatively connected to a container, and a valve needle equipped with a channel for the liquids and gases and a closed tip in the valve housing with the cylindrical valve seat is arranged movably such that the tip with seal in the closed state of the valve extends to the through hole The tip of the valve needle has an outer profile, over which the seal, preferably made of plastic, is located with an inner profile that is inverse to the outer profile. The profiles are designed in the manner of a snap lock A particularly tight fit of the seal on the tip of the valve needle is achieved. Even if the valve needle has been tightened with the aid of tools such as pliers or spanners, the seal can deform, and it will come loose when the valve is opened but not from the tip of the valve needle. This ensures that the valve remains operational even if it is not handled properly
Andererseits laßt sich zum Wechseln der Dichtung die auszutauschende Dichtung von der Spitze der Ventilnadel mittels eines Werkzeuges, beispielsweise einer Zange, in der Regel nur unter Zerstörung der Dichtung, zumindest aber des Innenprofils, entfernen Damit wird sichergestellt, daß nur neue intakte Dichtungen für eine Neubestuckung verwendet werden können Die Neubestuckung erfolgt dabei so, daß die neue Dichtung mit der Dichtflache nach unten auf eine glatte Unterlage gelegt wird und die Ventilnadel mit der profilierten Spitze in die Profiloffnung der Dichtung hinein gedruckt wird, bis die Profile einrasten Das Ventil laßt sich mit einfachen Mitteln auch von wenig erfahrenem Personal sicher warten Ein weiterer Vorteil besteht dann, daß durch die Ausgestaltung der Profile keine Totraume zwischen der Dichtung und der Ventilnadel entstehen, in denen sich schwer entfernbare Verunreinigungen ansammeln konnten In einer bevorzugten Ausführungsform der Erfindung ist die Dichtung in ihrem Frontbereich zur Abdichtung der Durchgangsbohrung trapezförmig ausgebildet, wodurch ein besonders guter Sitz der Dichtung im geschlossenen Zustand des Ventils erreicht wirdOn the other hand, to replace the seal, the seal to be replaced can be removed from the tip of the valve needle by means of a tool, for example pliers, as a rule only by destroying the seal, or at least the inner profile. This ensures that only new intact seals for new equipment The new equipment can be used so that the new seal is placed with the sealing surface facing down on a smooth surface and the valve needle with the profiled tip is pressed into the profile opening of the seal until the profiles snap into place Safe maintenance even by inexperienced personnel. Another advantage is that the design of the profiles means that there are no dead spaces between the seal and the valve needle in which contaminations that are difficult to remove could accumulate. In a preferred embodiment of the invention, the seal is in its front area to seal the through hole trapezoidal, whereby a particularly good fit of the seal is achieved in the closed state of the valve
