Abstract

The valve seat is attached to a central tube connected to a top plate. The valve head slides within the central tube and when the valve is fully open the perforations are fully exposed to the fluid flow. The central tube is surrounded by a larger perforated cylinder and the annular space between tube and cylinder is filled with layers of balls separated by a series of flat plates. The noise damping can be controlled by varying the resistance offered by the valve to the fluid flowing through it. The resistance can be varied by raising or lowering the valve head to expose varying numbers of layers of the balls.

Description

Schalldämpfende Durchflußstrecke mit regelbarem Widerstand Die Erfindung betrifft eine schalldämpfende Durchflußstrecke, die zum Einbau in Armaturen geeignet ist und deren Widerstand verändert werden kann.Sound-absorbing flow path with adjustable resistance The invention relates to a sound-absorbing flow path that is suitable for installation in fittings and whose resistance can be changed.

Bei der Drosselung strömender Stoffe in Regelarmaturen entstehen Strömungsgeräusche. Diese können bei überkritischen Entspannungen so laut werden, daß sie für die Umgebung eine unerträgliche Belästigung darstellen.Flow noises occur when flowing substances are throttled in control valves. During supercritical relaxation, these can become so loud that they affect the environment represent an intolerable nuisance.

Zur Lärmminderung werden Regelarmaturen mit schallmindernden Einbauten ausgerüstet, die hauptsächlich nach zwei Prinzipien arbeiten; nämlich Parallel- undioder Reihenschaltung von Drosselstellen.Control valves with noise-reducing fittings are used to reduce noise equipped that work mainly on two principles; namely parallel andior series connection of throttling points.

Parallelschaltung kann in Form von Löchkäfigen ausgeführt werden. Hierbei wird der Durchflußwiderstand so geregelt, daß je nach Stellung des Ventilkegels mehr oder weniger Öffnungen freigegeben werden.Parallel connection can be implemented in the form of perforated cages. The flow resistance is regulated in such a way that, depending on the position of the valve cone more or fewer openings are released.

Die Reihenschaltung von Widerständen wird beispielsweise in Form von Labyrinthkanälen ausgeführt, deren Durchfluß in gleicher Weise wie bei den Lochkäfigen geregelt wird.The series connection of resistors is for example in the form of Labyrinth channels run, their flow in the same way as with the perforated cages is regulated.

Es ist aber auch Geräuschminderung möglich durch Festwiderstände, die hinter der Regelarmatur eingebaut sind; beispielsweise Lochscheiben, Raschig-Ringe und Kugelschüttungen.However, noise reduction is also possible through fixed resistors, which are installed behind the control valve; for example perforated disks, Raschig rings and pebbles.

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

Nachstehend wird die Erfindung anhand des dargestellten schematischen Beispiels näher erläutert: Es zeigt Fig. 1 die Schnittdarstellung einer schalldämpfenden Durchflußstrecke, eingebaut in ein Regelventil. Das Regelventil ist teilweise geöffnet.The invention is described below with reference to the illustrated schematic Explained in more detail by way of example: FIG. 1 shows the sectional view of a sound-absorbing Flow path built into a control valve. The control valve is partially open.

Fig. 2 die Schnittdarstellung einer schalldämpfenden Durchflußstrecke als Bauteil und zwar ohne den Verschlußkörper.Fig. 2 shows the sectional view of a sound-absorbing flow path as a component without the closure body.

Der Verschlußkörper (1) steht in einer Zwischenstellung. Dadurch wird ein Teil der Durchflußöffnungen (2) freigegeben. Die Durchflußöffnungen (2) werden begrenzt durch die Trennscheiben(3) und Kugeln (4). Der innere Lochkäfig (5) und der äußere Lochkäfig (6) hindern die Kugeln (4) am Herausfallen. An der unteren Seite wird die Kugelschüttung durch den Sitz (7) und auf der oberen Seite durch die Druckplatte (8) begrenzt.The closure body (1) is in an intermediate position. This will some of the flow openings (2) are released. The flow openings (2) are limited by the cutting discs (3) and balls (4). The inner perforated cage (5) and the outer perforated cage (6) prevent the balls (4) from falling out. At the bottom The pebble bed is on the side through the seat (7) and through on the upper side the pressure plate (8) is limited.
