Lautlose, mechanisch betriebene Drosselklappe für lufttechnische AnlagenSilent, mechanically operated throttle valve for air-conditioning systems

In lufttechnische Anlagen, die in verstärktem Maße als Kombination Lüftung und Heizung realisiert werden, werden zur Regelung des Luftdurchsatzes bzw. der zugeführten Wärmeenergie Drosselklappen eingesetzt. Bekannte Drosselklappen für kleinere Rohrquerschnitte arbeiten mit Ausdehnungsstellgliedern mit relativ kleiner Hubbewegung.In air-conditioning systems, which are increasingly being implemented as a combination of ventilation and heating, throttle valves are used to regulate the air flow or the heat energy supplied. Known throttle valves for smaller pipe cross-sections work with expansion actuators with a relatively small stroke movement.

Die Konstruktion dieser Klappen in Bezug auf die Verbindungsglieder zwischen Stellglied und Drosselklappe setzt voraus, daß bei Wartung und Instandsetzung der ganze betreffende Rohrabschnitt ausgetauscht werden muß. Diese Nachteile werden erfindungsgemäß dadurch behoben, daßThe design of these flaps in relation to the connecting elements between the actuator and the throttle valve requires that the entire pipe section in question must be replaced during maintenance and repair. These disadvantages are eliminated according to the invention by

auch bei Anwendung vorbenannter Stellglieder der kurze Hub voll auf die Bewegung von Drosselklappen großen Querschnittes umgesetzt wird, indem das System lediglich aus einem aktiven Teil (Klappe) besteht und sämtliche weiteren Teile, wie Pleul mit Achsstiften etc. vermieden werden. Weiterhin ist es durch den gabelförmigen Eingriff möglich, das Verschleißteil von außen auszuwechseln, ohne daß Rohrabschnitte demontiert werden müssen.Even when using the aforementioned actuators, the short stroke is fully converted to the movement of throttle valves with a large cross-section, as the system consists of only one active part (valve) and all other parts, such as connecting rods with axle pins, etc. are avoided. Furthermore, the fork-shaped intervention makes it possible to replace the wearing part from the outside without having to dismantle pipe sections.

Die Erfindung wird an folgendem Ausführungsbeispiel beschrieben:The invention is described using the following embodiment:

Eine WeIIeI, welche die Drosselklappe 2 trägt, ist an einer Seite im Lüftungsrohr 3 mit Stiftschrauben 4 gelagert und an der anderen Seite durch die Rohrwandung hindurch im Bügel 5, der gleichzeitig Befestigung für das Stellglied 6 ist, gelagert.A shaft which carries the throttle valve 2 is mounted on one side in the ventilation pipe 3 with stud bolts 4 and on the other side through the pipe wall in the bracket 5, which is also the fastening for the actuator 6.

In einer Verdickung der Welle 1 ist mit Freimachung 7 der Antriebsstift 8 konzentrisch eingesetzt. Zur Vermeidung von Nebenluft ist zwischen Bügel 5 undThe drive pin 8 is inserted concentrically in a thickening of the shaft 1 with a clearance 7. To avoid secondary air, a spacer is provided between the bracket 5 and

Rohrwandung eine Gummischürze 9 eingesetzt. r"„\A rubber apron 9 is inserted into the pipe wall. r"„\

Das Stellglied 6 ist tangential zur Welle 1 in dem Bügel 5 verschraubt und trägt die Antriebsgabel 10, die wegen beliebiger Einschraubstellung rotationssymmetrisch ausgeführt ist.The actuator 6 is screwed tangentially to the shaft 1 in the bracket 5 and carries the drive fork 10, which is designed to be rotationally symmetrical because it can be screwed into any position.

Mit der Erfindung wird eine wartungsarme Drosselklappe mit sicherer Funktion angeboten, die an beliebiger Stelle im gesamten Rohrsystem eingesetzt werdenThe invention offers a low-maintenance throttle valve with reliable function that can be used anywhere in the entire pipe system
