Abstract

The valve head (1) slides in a cylindrical space surrounded by a stack of corrugated discs (3) which extend from the valve seat (7) to a cover plate (8). The corrugated discs are secured at a uniform distance from each other by collars and the assembly is held together by bolts. The position of the valve head (1) determines the effective area of cross section (3) of the fluid flowing through the valve and this in turn controls the resistance to flow which can be adjusted to reduce the noise to a minimum. The use of corrugated discs closely spaced provides a high degree of resistance and a corresponding reduction in noise.

Drosselstrecke mit aufgeteilten Strömungsquerschnitten und regelbarem Widerstand.Throttle section with split flow cross-sections and adjustable resistance.

Die Erfindung betrifft eine Drosselstrecke mit schichtweise aufgeteilten Strömungsquerschnitten, die zum Einbau in Regelarmaturen geeignet ist.The invention relates to a throttle section with flow cross-sections divided into layers, which are intended for installation in control valves suitable is.

Bei der Drosselung strömender Stoffe in Regelarmaturen entstehen Strömungsgeräusche, die das zulässige Maß besonders dann überschreiten, wenn sehr hohe Drücke in der Armatur entspannt werden.When flowing substances are throttled in control valves, flow noises occur which are particularly high in the permissible range exceed when very high pressures are released in the valve.

Zur Lärmminderung werden Schalldämpfer verwendet oder auch schallmindernde Drosselstrecken in die Regelarmaturen eingebaut; beispielsweise als Lochkäfige oder Reihenschaltung von Widerständen. Die Reihenschaltung von Widerständen wird beispielsweise in Form von Labyrinthkanälen ausgeführt, wobei im Labyrinthkanal mehrere Widerstände hintereinander geschaltet sind. Eine Durchflußkennlinie wird dadurch erreicht, daß eine größere Anzahl von Labyrinthkanälen parallel geschaltet sind und daß ein Ventilkegel mehr oder weniger Kanäle frei gibt oder absperrt.To reduce noise, silencers are used or noise-reducing throttles are built into the control valves; for example as perforated cages or series connection of Resistances. The series connection of resistors is implemented, for example, in the form of labyrinth channels, with Several resistors are connected in series in the labyrinth channel. A flow characteristic is achieved in that a larger number of labyrinth channels are connected in parallel and that a valve cone more or less channels are free gives or shuts off.

Der Erfindung lag die Aufgabe zugrunde einen regelbaren Durchflußwiderstand zu schaffen, der mit einfachen Konstruktionselementen eine geräuscharme Drosselung ermöglicht. The invention was based on the object of a controllable flow resistance to create, which enables a low-noise throttling with simple construction elements.

Nachstehend wird die Erfindung anhand des dargestellten schematischen Beispiels näher erläutert:The invention is described below with reference to the illustrated schematic Example explained in more detail:

In Fig. 1 ist der Verschlußkörper (1) in einer Zwischenstellung dargestellt. Dadurch wird ein Teil der Durchflußöffnungen (2) freigegeben. Die Durchflußöffnungen (2) werden begrenzt durch die Begrenzungswände (3) deren Abstände durch Distanzstücke (M-) hergestellt werden. Mittels Bolzen (5) und Muttern (6) werden die Begrenzungswände (3) und Distanzstücke (1O zusammengespannt wobei der Sitzring (7) und die Druckplatte (8) die untere und obere Begrenzung des Drosselstrecken-Pakets bilden. Der Verschlußkörper (1) gleitet an der Innenkontur (9) der Begrenzungswände (3) und erhält dort seine Führung. In Fig. 1, the closure body (1) is shown in an intermediate position. This releases part of the flow openings (2). The flow openings (2) are delimited by the boundary walls (3), the distances between which are made by spacers (M-). By means of bolts (5) and nuts (6) the limiting walls (3) and spacers (1 O are clamped together with the seat ring (7) and the pressure plate (8) form the lower and upper limit of the throttle sections packet. The closure body (1) slides on the inner contour (9) of the boundary walls (3) and is guided there.
