Description
Pestwiderstand für fluidische Ströme Die Erfindung betrifft einen Festwiderstand zur Begrenzung gasförmiger oder flüssiger Ströme, insbesondere für pneumatische oder fluidische Steuerungs- und Regelungseinrichtungen. Pest resistance for fluidic flows The invention relates to one Fixed resistance to limit gaseous or liquid flows, especially for pneumatic or fluidic control and regulation devices.
Bei derartigen Einriehtungen müssen z.B. zur Erzielung von Zeitverzögerungen, zur Dämpfung von Druckstößen oder ganz allgemein zur Begrenzung des Durchflusses Leitungsverengungen, Widerstände eingebaut werden.With such arrangements, e.g. to achieve time delays, for damping pressure surges or in general for limiting the flow Line constrictions, resistors are built in.
Es ist bekannt, zu diesem Zwecke verstellbare Widerstände, Drosselventile, einzubauen. In Fällen, in denen eine Verstellbarkeit nicht notwendig oder nicht erwünscht ist, werden Festwiderstände in Form von Lochblenden eingesetzt.It is known to use adjustable resistors, throttle valves, to be built in. In cases where adjustability is not necessary or not If desired, fixed resistors in the form of perforated diaphragms are used.
Zur Erzielung einer guten Reproduzierbarkeit der Durchflußwerte müssen diese Lochblenden sehr sorgfältig hergestellt werden, was bei spanender Bearbeitung aufwendig ist.In order to achieve a good reproducibility of the flow values these apertured diaphragms are manufactured very carefully, which is what happens when machining is expensive.
Außerdem müssen sie in eine entsprechende Halterung eingepreßt oder eingeschraubt werden (Zeitschrift am+r, Jahrgang 1969, Heft 9 S.215).In addition, they must be pressed into a suitable holder or screwed in (magazine am + r, year 1969, issue 9 p.215).
Der Erfindung liegt die Aufgabe zugrunde, den Aufbau und die Handhabung von Pestwiderständen zu vereinfachen und die Möglichkeit zu schaffen, durch Kombination einer kleinen Anzahl gleichartiger Bauteile mit unterschiedlichen Blendendurchmessern eine größere Anzahl verschiedener Durchflußwerte zu erzielen.The invention is based on the object of the structure and handling of plague resistances and to create the possibility by combination a small number of similar components with different orifice diameters to achieve a greater number of different flow rates.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Festwiderstand aus zwei gleichartigen Hälften besteht, die die den Durchfluß bestimmenden Drosselbohrungen enthalten und die - über ein Paßstück zentriert - unlösbar miteinander verbunden werden. Jeder der beiden trichterförmigen Hälften ist als Schlauchtülle ausgebildet und mit einem Ansatz versehen, der die Angriffsfläche bildet für die Kraft zum Aufschieben oder Abziehen eines Schlauches.This object is achieved according to the invention in that the fixed resistor consists of two halves of the same type, which form the throttle bores which determine the flow rate and which - centered on a fitting piece - are inextricably linked will. Each of the two funnel-shaped halves is designed as a hose nozzle and provided with an approach which forms the contact surface for the force to push or pulling off a hose.
Die Zentrierung der beiden Hälften erfolgt vorzugsweise durch einen eingesetzten Filterkörper, der die stromabwärts liegende Drosselbohrung vor Verschmutzung schützt.The centering of the two halves is preferably done by one filter body used, which protects the downstream throttle bore from contamination protects.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die so aufgebauten Festwiderstände einfach und billig herzustellen sind, daß sie ohne Verwendung zusätzlicher Bauteile direkt in eine Schlauchleitung eingesetzt werden können und daß durch die unterschiedliche Kombination weniger Hälften eine größere Anzahl verschiedener Durchflußwerte erzielt werden kann.The advantages achieved with the invention are in particular: that the fixed resistors constructed in this way are simple and cheap to manufacture, that they are inserted directly into a hose line without the use of additional components can be and that by the different combination fewer halves one larger number of different flow rates can be achieved.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.
Es zeigt Fig. 1 einen Festwiderstand, bestehend aus den beiden Hälften 1 und 2 mit den Drosselbohrungen 3 und 4 und der zum Festhalten eines Schlauches erforderlichen Verzahnung 5. Die beiden Hälften 1 und 2 sind über den Filterkörper 6 geschoben und bei 7 durch Kleben oder Schweißen unlösbar miteinander verbunden. It shows Fig. 1 a fixed resistor consisting of the two halves 1 and 2 with the throttle bores 3 and 4 and the one for holding a hose required toothing 5. The two halves 1 and 2 are over the filter body 6 pushed and at 7 permanently connected to one another by gluing or welding.
