This is achieved in that said diaphragm has at least one sensor (8, 10) for overload and/or wear monitoring.

Description

MEMBRAN EINES MEMBRANVENTILS MEMBRANE OF A MEMBRANE VALVE
Die Erfindung betrifft eine Membrane für Membranventile, insbesondere Standard-Membranventile, Bodenablassventile, Blockventile, T-Ventile, Tandemventile, Multiportventile und/oder Schweißkonstruktionsventile .The invention relates to a diaphragm for diaphragm valves, in particular standard diaphragm valves, bottom drain valves, block valves, T-valves, tandem valves, multiport valves and / or welded construction valves.
Derartige Ventile werden bei einer Vielzahl industrieller und gewerblicher Vorgänge eingesetzt und führen bei einem plötzlichen und unerwarteten Defekt zu unnötigen und häufig sehr kostenträchtigten Stillstandzeiten. Aus diesem Grund werden die Membranen häufig vorsorglich ausgewechselt, und zwar schon lange vor einem möglichen Defekt. Dadurch entstehen ebenfalls unnötige Material- und Arbeitskosten. Im Vordergrund steht jedoch stets der Gesichtspunkt der maximal möglichen Sicherheit, vor allem im Bereich der Lebensmittelproduktion, im Pharma- und Kosmetikbereich, der Chemie, Petrochemie und Halbleiterherstellung.Such valves are used in a variety of industrial and commercial operations and result in a sudden and unexpected defect to unnecessary and often very costly downtime. For this reason, the membranes are often replaced as a precaution, and indeed long before a possible defect. This also creates unnecessary material and labor costs. However, the focus is always on the maximum possible safety, especially in the area of food production, in the pharmaceutical and cosmetics sector, in the chemical, petrochemical and semiconductor industries.
Aufgabe der Erfindung ist es daher, eine Membrane zu schaffen, die erst dann ausgewechselt werden muss, bzw. ausgewechselt werden kann, bevor tatsächlich ein Defekt auftritt.The object of the invention is therefore to provide a membrane that only needs to be replaced, or can be replaced before a defect actually occurs.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, dass die Membrane wenigstens einen Sensor zur Belastungs- und/ oder Verschleißkontrolle aufweist.This object is achieved according to the invention in that the membrane has at least one sensor for load and / or wear control.
Hiermit wird erreicht, dass Membranen erst kurz vor ihrer Zerstörung und zeitnah ausgewechselt werden können und müssen.This ensures that membranes can and must be replaced shortly before their destruction and in a timely manner.
Die erfindungsgemäße Membrane weist beispielsweise einen Tex- tilsensor auf. Mit derartigen fadenförmigen Sensoren aus Tex- tilwerkstoffen ist eine Überlastungs- und Verschleißkontrolle möglich. Reißt der Sensorfaden durch oder wird er über ein zuvor definiertes Maß hinaus gedehnt, wird das durch diesen ausgelöste Signal unterbrochen, so dass aufgrund einer entsprechenden Anzeige in einem Überwachungsgerät oder -räum eine rechtzeitige Membranauswechselung veranlasst werden kann. Derartige Textilsensoren können auch aus leitfähigen Nanokom- positmaterialien bestehen. Diese werden etwa durch eine spino- dale Zersetzung in geeigneten quasi-binären-Systemen (z.B. Titannitrid und Sili-Cium-Nitrid (TiN und Si3N4)) gebildet werden und sind nur einige Nanometer große Kristalle, die durch eine etwa eine Monolage dicke zweite Phase zusammengehalten werden. Eine solche Nanostruktur ist wesentlich stärker als perfekte Einkristalle der beiden Phasen. Da die praktisch erreichbare Festigkeit von Materialien durch Baufehler wie Versetzungen, Mikrorisse, Korngrößen, etc. begrenzt ist, können diese neuen, auf chemischem Wege durch Selbstorganisation entstandenen Nanokomoposite eine sehr hohe, mit Diamant vergleichbare Härte erreichen. Darüber hinaus weisen diese eine sehr hohe Oxidationsbeständigkeit auf.The membrane according to the invention has, for example, a textile sensor. Such filament-shaped sensors made of textile materials enable overload and wear control. If the sensor thread breaks or is stretched beyond a previously defined extent, the signal triggered by it is interrupted so that a timely replacement of the membrane can be initiated on the basis of a corresponding display in a monitoring device or space. Such textile sensors can also consist of conductive nanocomposite materials. These are formed, for example, by spinidal decomposition in suitable quasi-binary systems (eg, titanium nitride and silicon-cium nitride (TiN and Si3N4)) and are only nanometer-sized crystals through a second phase about one monolayer thick held together. Such a nanostructure is much stronger than perfect single crystals of the two phases. Since the practically achievable strength of materials is limited by structural defects such as dislocations, micro-cracks, grain sizes, etc., these new, by chemical means by self-organization nanocomposites can achieve a very high comparable with diamond hardness. In addition, these have a very high oxidation resistance.
In einer anderen Ausgestaltung sieht die Erfindung einen Tex- tilsensor in Form wenigstens eines Dehnungssensors aus Silikon vor. Auch kommen Hitzesensoren auf Basis von Heißsiegelfäden in Betracht. Ebenso kann ein Kontrollreißfaden auf der Grundlage versilberter Nylonfäden vorhanden sein.In another embodiment, the invention provides a textile sensor in the form of at least one strain sensor made of silicone. Also, heat sensors based on heat-sealing threads come into consideration. Likewise, a control tear thread based on silver-plated nylon threads may be present.
Schließlich kommen auch Lichtleitfäden in Betracht, insbesondere aus Polymethylmetazylat.Finally, optical fibers are also suitable, in particular polymethylmetazylate.
Sämtliche Sensoren können insbesondere fadenförmig ausgebildet sein, beispielsweise die Kontrollreißfaden, Dehnungssensoren und Hitzesensoren.All sensors may be formed in particular filiform, for example, the control thread, strain sensors and heat sensors.
Kontrollreißfaden lassen auf einfache Weise erkennen, ob eine bestimmte Dehnung oder Spannung überschritten wurde. Dabei macht man sich die mechanischen Eigenschaften des Kontroll- reißfadens zu nutze, die auf das umgebende Textil abgestimmt sein müssen. Bei erfolgreicher Abstimmung reißt der Kontrollreißfaden aufgrund zu hoher Dehnung noch bevor das Textil versagt. Das Reißen des Sensorfadens kann rein optisch erfasst werden, sofern der Sensorfaden auf der Textiloberflache sichtbar ist.Control tears make it easy to see if a certain stretch or tension has been exceeded. In doing so, one makes use of the mechanical properties of the control thread, which must be matched to the surrounding textile. If the tuning is successful, the control thread will tear because of excessive stretching even before the fabric fails. The tearing of the sensor can be detected purely optically, as long as the sensor thread is visible on the textile surface.
Er kann aber insbesondere auch durch die Ausnutzung physikalischer Effekte detektiert werden. Dabei macht man sich den Effekt zu nutze, dass mit dem Reißen des Fadens das Signal unterbrochen wird. Das gilt sowohl für optisch, wie auch für elektrisch leitende Fäden. Derartige Kontrollreißfäden müssen nicht zwangsweise an der Oberfläche der Membran eingebracht, sondern können auch in deren Inneres integriert werden. Insbesondere ist eine Integration in die lastaufnehmenden Komponenten und die am meisten reiß- oder bruchgefährdeten Bereiche möglich.However, it can also be detected in particular by exploiting physical effects. In doing so, one makes use of the effect that the signal is interrupted by the tearing of the thread. This applies to both optical as well as electrically conductive threads. Such control tear threads need not necessarily be introduced at the surface of the membrane, but can also be integrated into their interior. In particular, integration in the load-bearing components and the most tear or breakage-prone areas is possible.
Als stromleitende Fäden kommen insbesondere versilberte Nylonfäden in Betracht, beispielsweise aus zwei verzwirnten Nylonfilamenten, die mit einer Silberbeschichtung versehen sind.Particularly suitable as current-conducting filaments are silver-plated nylon filaments, for example two twisted nylon filaments which are provided with a silver coating.
Bei lichtleitenden Fäden handelt es sich z.B. um geschlossene Lichtwellenleiter mit Kern-Mantel-Aufbau. Der lichtführende Kern besteht insbesondere aus Polymethylmethacrylat mit einem Brechungsindex von 1,49 und einer numerischen Apertur von 0,5. Dieser ist mit einer 5 mm dicken Schicht fluoriertem Polymer ummantelt, die den Lichtstahl durch Reflektion am Verlassen der Kernhülle hindert. Die Feinheit des Fadens beträgt 600 dtex.For example, light-conducting filaments are closed fiber optic cable with core-shell-construction. The light-guiding core consists in particular of polymethyl methacrylate with a refractive index of 1.49 and a numerical aperture of 0.5. This is covered with a 5 mm thick layer of fluorinated polymer, which prevents the light beam by reflection from leaving the nuclear envelope. The fineness of the thread is 600 dtex.
Die angegebenen Dehnungssensoren nutzen die Änderung des elektrischen Widerstandes eines leitfähigen Polymerfadens in Abhängigkeit von seiner Dehnung aus, um über eine Widerstandsmessung die Dehnung zu ermitteln. So gibt es beispielsweise mit Ruß gefüllte Silikonfäden mit Duchmessern von 0,5 und 1,0 mm. Als Hitzesensoren werden Fäden vorgeschlagen, die unter Wärmeeinwirkung ihre Form, Farbe oder Steifigkeit verändern. Hier gibt es insbesondere sogenannte Heißsiegelfäden, bei denen sich die Fadenkräuselung bzw. -Steifigkeit im Laufe der Zeit verändert .The specified strain sensors make use of the change in the electrical resistance of a conductive polymer thread as a function of its elongation in order to determine the elongation via a resistance measurement. For example, there are silicon filaments filled with carbon black with diameters of 0.5 and 1.0 mm. As heat sensors threads are proposed, which change their shape, color or stiffness under heat. Here there are in particular so-called heat-sealing threads, in which the thread curl or stiffness changes over time.
Die fadenförmigen Sensoren können auch als Gewerbeeinlage ausgebildet sein, um eine großflächige Detektion der Membrane zu ermöglichen.The thread-like sensors can also be designed as a commercial insert to enable a large-area detection of the membrane.
Die Sensorsignale sind erfindungsgemäß an einer beliebigen Stelle der Membrane, fallweise auch über eine Membranadaption abgreifbar. Dies hat den Vorteil, dass verschiedenste Membrantypen und Membrangehäuse, beispielsweise auch Membranventilkörper mit Zentralgewinde, hiermit ausgestattet und zum Einsatz kommen können.According to the invention, the sensor signals can be tapped at any point on the membrane, in some cases also via a membrane adaptation. This has the advantage that a wide variety of membrane types and membrane housing, for example, diaphragm valve body with central thread, hereby equipped and can be used.
Das abgegriffene Signal wird durch eine nachgeschaltete Messelektronik oder Auswerteschaltung ausgewertet. Gerade bei elektrischen oder optisch leitenden Fäden ist eine einfache Auswertung des Signals mittels Durchgangsprüfung möglich.The tapped signal is evaluated by a downstream measuring electronics or evaluation circuit. Especially with electrical or optically conductive threads a simple evaluation of the signal by means of continuity testing is possible.
Die Erfindung ist nachstehend anhand der Zeichnung beispielhaft näher erläutert. Diese zeigt in:The invention is explained in more detail below by way of example with reference to the drawing. This shows in:
Fig. 1 eine Seitenansicht einer erfindungsgemäßen Memban mit eingebettetem Textilsensor,1 is a side view of a membrane according to the invention with embedded textile sensor,
Fig. 2 eine Aufsicht auf eine herkömmliche Membran mit aufgeklebtem fadenförmigen Sensor und Signalabgriff.Fig. 2 is a plan view of a conventional membrane with glued thread-like sensor and signal pickup.
Eine erfindungsgemäße, allgemein mit 1 bezeichnete Membran für nicht näher dargestellte Membranventile weist einen Membrankörper 2 und einen Verbindungsstift 3 in der Mitte auf. Dieser Verbindungsstift 3 ist mit einem innenliegenden Pluspol 4 und einem äußeren Minuspol 5 versehen und über Leitungen 6, 7 mit einem Sensorfaden 8 verbunden, der eng in das Gewebe 9 der Membran 1 eingeflochten ist. Kommt es zu einer Überlastung oder einem Verschleiß der Membran 1, wird der Sensorfaden 8 über ein vordefiniertes Maß gedehnt oder reißt gar ganz. Hierdurch wird das vom Sensorfaden 8 ausgelöste Signal unterbrochen. Über eine entsprechende, nicht näher dargestellte Auswerteschaltung erfolgt eine Anzeige in einem Überwachungsgerät oder -räum, von wo aus eine rechtzeitige Auswechselung veran- lasst werden kann. Hierdurch werden erhebliche Produktionsstillstände, -Störungen und dergleichen vermieden.An inventive, generally designated 1 membrane for diaphragm valves, not shown, has a membrane body 2 and a connecting pin 3 in the middle. This connecting pin 3 is provided with an inner positive pole 4 and an outer negative pole 5 and via lines 6, 7 with connected to a sensor thread 8, which is intertwined in the fabric 9 of the membrane 1. If it comes to an overload or wear of the membrane 1, the sensor thread 8 is stretched over a predefined amount or even tears completely. As a result, the triggered by the sensor thread 8 signal is interrupted. By means of a corresponding evaluation circuit (not shown in more detail), a display is made in a monitoring device or room, from where a timely replacement can be initiated. As a result, significant production stoppages, disturbances and the like are avoided.
Figur 2 zeigt in einer alternativen Ausführungsform eine Aufsicht auf eine herkömmliche, in diesem Fall viereckige Membran 1 mit einem Membrantypenindex (Lappen) 14 und vier Befestigungslöchern 15, ohne dass die Ausführung der Erfindung auf eine solche Gestaltung beschränkt wäre. Vielmehr sind auch quadratische, runde, ovale und sonstige Membranen ebenso ausrüstbar. Auf der Oberfläche 12 der Membran 1 ist beispielsweise ein äußerer Sensorfaden 10 in geeigneter Art und Weise angebracht, beispielsweise aufgeklebt, aufvulkanisiert oder dergleichen. Auch dieser wird wieder über eine Membranadaption 11, 13 abgegriffen und einer Auswerteschaltung, Messelektronik oder dergl. zugeführt.Figure 2 shows, in an alternative embodiment, a plan view of a conventional, in this case, quadrangular membrane 1 with a membrane type index (tab) 14 and four fastening holes 15, without limiting the embodiment of the invention to such a design. Rather, square, round, oval and other membranes are also available. On the surface 12 of the membrane 1, for example, an external sensor thread 10 is attached in a suitable manner, for example glued, vulcanized or the like. This is again tapped via a membrane adaptation 11, 13 and fed to an evaluation circuit, measuring electronics or the like.
Natürlich ist die Erfindung nicht auf die dargestellten Ausführungsbeispiele beschränkt. Weitere Ausgestaltungen sind möglich, ohne den Grundgedanken zu verlassen. Wesentlich ist nur, dass die Membrane 1 überhaupt einen Sensor 8, 10 zur Überlast- und/oder Verschleißkonrolle aufweist. Of course, the invention is not limited to the illustrated embodiments. Further embodiments are possible without departing from the basic idea. It is only important that the membrane 1 has a sensor 8, 10 for overload and / or Verschleückkonrolle at all.
