Abstract
Description
Volumenstromregler üblicher Bauart bestehen aus einem äusseren Gehäuse mit innenliegendem Reglerblatt in quadratisch, rechteckig oder runder Form, welche über eine Achse gedreht und somit eine Volumenstrommenge einreguliert werden kann. Auch gibt es sog. Jalousieklappen, in welchen über- oder nebeneinanderliegende Reglerblätter synchron über Zahnräder oder Gestänge verdreht werden können. Der Antrieb kann manuell, elektrisch oder pneumatisch erfolgen. Üblicherweise werden diese Regler nur in metallener Werkstoffausführung angeboten.Volume flow controller usual Type consist of an exterior casing with internal regulator blade in square, rectangular or round Form, which over rotated an axis and thus regulated a volume flow amount can be. There are also so-called shutter valves, in which over- or adjoining regulator blades synchronously over gears or linkage can be twisted. The drive can be manual, electrical or pneumatic. Usually these regulators are offered only in metallic material version.
Ein Einsatz in bestimmten, agenzienverunreinigten Luftvolumenströmen, wie sie z. B in Labordigestorien vorkommen, ist nur beschränkt möglich, d. h. ein Einsatz von Metallwerkstoffreglern ist wg. der abgeführten, aggressiven Abluft und des damit verbundenen Verschleisses nur zeitlich begrenzt möglich. Darüber hinaus lassen sich solche Regler im „Defektfall" nur nach Ausbau der gesamten Einheit eventuell reparieren oder ersetzen. Auch eine exakte Definition der freien Fläche zur Ermittlung der Volumenstrommenge ist an der benannten Art Regler nicht möglich. Zur Strömungsmessung muss eine geeignete Messstrecke ober- oder unterhalb des Reglers gewählt werden, um dort die Geschwindigkeit oder den Differenzdruck zu messen, welcher für die Ermittlung der Volumenstrommenge notwendig wäre. Desweiteren sind Defekte von aussen nicht zu erkennen, da Inspektionsöffnungen üblicherweise nicht vorhanden sind.One Use in certain agent contaminated air flow rates, such as they z. B occur in laboratory strictures, is limited, d. H. a use of metal material regulators is wg. the discharged, aggressive Exhaust air and the associated wear only temporarily possible. Furthermore can such controllers in the "defect" only after removal Repair or replace the entire unit if necessary. Also an exact one Definition of the free area to determine the volume flow amount is not at the named type controller possible. For flow measurement must have a suitable measuring section above or below the controller chosen be used to measure the speed or differential pressure there, which for the determination of the volumetric flow volume would be necessary. Furthermore, there are defects Not visible from the outside, since inspection openings usually not available are.
Der im Patentanspruch 1 angegebenen Erfindung lag das vorher beschriebene Problem zugrunde, dafür einen Volumenstromregler zu konstruieren, der 1. im Reparatur- oder Inspektionsfall einen Ausbau des kompletten Reglers überflüssig macht; 2. auch in agenzienverunreinigtem Volumenstrom problemlos arbei tet und 3. der in jeder Klappenstellung per Tabelle eine klar definierte freie Fläche hat.Of the specified in claim 1 invention was the previously described Problem, for that to construct a volumetric flow regulator, the 1st in the repair or Inspection case makes an expansion of the complete controller superfluous; Second even in agent contaminated volume flow without any problems and 3. the in each flap position per table a clearly defined free area Has.
Dieses Problem wird mit den im Patentanspruch 1 bis 9 aufgeführten Merkmalen gelöst.This Problem is with the features listed in claim 1 to 9 solved.
Mit der Erfindung wird erreicht, dass 1. die im Innengehäuse untergebrachten Funktionsteile nach Abnahme einer Revisionsklappe am Aussengehäuse insgesamt herausgezogen werden können. Dazu muss lediglich noch der nicht verschraubte Umlenkhebel zur Seite ausgehangen werden. Der Gesamtzeitaufwand liegt bei maximal 2 Minuten; 2. die vorzugsweise verwendeten Werkstoffe sind bei Einsatz in agenzienverunreinigten Volumenströmen weitestgehend resistent und 3. die tabellarisch festgehaltenen freien Flächen in 100 Klappenpositionen lassen eine sehr einfache Einstellung der Volumenstrommengen zu. Die Messung erfolgt am Regler selbst über zwei Messbohrungen ober- und unterhalb des Trennbodens einmal bei voll geöffnetem Regler mit Differenzdruckmanometer. Ein einfaches Berechnungsprogramm kann dann alle Volumenstrommengen in allen übrigen Reglerstellungen definieren. Einzige Voraussetzung für den Einsatz eines Berechnungsprogramms ist stationäre Strömung, wie sie jedoch bei Anlagen mit Vordruckkanälen gegeben ist.With the invention is achieved that 1. accommodated in the inner housing Functional parts after removal of a revision flap on the outer housing as a whole can be pulled out. All you have to do is screw the non-bolted lever to the Side be hung. The total time required is maximum 2 minutes; 2. the materials preferably used are when used in Agent contaminated flow rates largely resistant and 3. the tabulated free areas in 100 flap positions allow a very simple adjustment of volume flow rates. The measurement is carried out on the controller itself via two measuring bores. and below the dividing shelf once with fully open regulator with differential pressure gauge. A simple calculation program can then calculate all volume flow rates in all the rest Define controller positions. Only condition for the employment A computational program is stationary flow, as in plants with pre-pressure channels given is.

Ausführungsbeispiel
wird anhand der
Durch einen Standard-Steckmotor (links-/rechtsdrehend) als Sonderausführung mit Endschaltern aufgesteckt auf das Spindelende ausserhalb des äusseren Kanals wird die Spindel in eine vorgewählte Position gefahren und über die Endschalter gestoppt, wobei durch das Links-/Rechtsgewinde der Spindel die Spindelmuttern mit den Klappenaufnahmen und den daran aufgehängenen Gelenkklappen synchron zur Spindelmitte oder umgekehrt fahren. Auch manuell kann ein Klappenstellungswechsel über eine anstelle eines Steckmotors angebrachte Handkurbel, welche zur Standardausrüstung gehört, erzielt werden. Die Anströmung der Luft erfolgt durch die Grundplatte im äusseren Kanal gegen die darüber fest verbundenen Gelenkklappen, umströmt sie und tritt am oberen Ende des Innenkanals in eine weiterführende Luftleitung.By a standard plug-in motor (left / right-hand rotation) as special version with limit switches attached to the end of the spindle outside the outer channel is the spindle in a preselected Position driven and over stopped the limit switch, whereby by the left / right-hand thread of the Spindle the spindle nuts with the flap holders and the it up hängenen Move joint flaps synchronously to the spindle center or vice versa. Also manually, a flap position change over a mounted instead of a plug-in motor Hand crank, which belongs to the standard equipment, can be achieved. The flow of air takes place through the base plate in the outer channel against the above connected joint flaps, flows around she and enters at the upper end of the inner channel in a continuing air line.
