Description
und 5 angeordnet ist Die Klappen 4 und 5 sind gleich ausgebildet und haben ein Profil das sich ausgehend von der jeweiligen Schwenkachse 6 bzw. 8 zum freien Ende der Klappen hin verjüngt Das Schwenklager der Schwenkklappe 4 liegt etwa in der Ebene der Trenn- s wand am stromaufwärtsliegenden Anfang 7 der öffnung, während das Schwenklager 8 der Klappe S am stromabwärtsliegenden Ende 9 der öffnung angeordnet istand 5 is arranged. The flaps 4 and 5 are identical and have a profile that starts from the respective pivot axis 6 or 8 tapers towards the free end of the flaps Swivel flap 4 lies approximately in the plane of the partition wall at the upstream beginning 7 of the opening, while the pivot bearing 8 of the flap S is arranged at the downstream end 9 of the opening is
Die Klappen 4 und 5 sind in einem getrennten Lei- to tungsabschnitt angeordnet, der aus drei zwischen den Anschlußleitungen 10 und 28 paketierten Einzelab-.xhnitten 11,12 und 13 besteht In den quer zur Trennwand 3 verlaufenden Teilfugen 14 und 15 sind Lagerbohrungen 16,17,18 und 19 für die Wellenzapfen 20,21, is 22 und 23 der mit ihren Schwenkachsen einstückig aus Feinguß gefertigten Klappen 4 und 5 angeordnetThe flaps 4 and 5 are arranged in a separate line section consisting of three between the Connection lines 10 and 28 packaged individual sections 11, 12 and 13 consists in the butt joints 14 and 15 running transversely to the partition 3, there are bearing bores 16, 17, 18 and 19 for the shaft journals 20, 21, is 22 and 23 of the one piece with their pivot axes Investment cast made flaps 4 and 5 arranged
An den Wellenzapfen 22 und 23 der Schwenkachsen 6 und 8 greifen Hebel 24 und 25 an, die über einen gemeinsamen Verbindungsbolzen 26 betätig.« werden. Der das Betätigungselement für die erste Klappe 5 bildende Hebel 25 ist mit dem das Betätigungselement für die zweite Schwenkklappe 4 bildenden Hebel 24 derart gekoppelt daß bei geschlossener Öffnung beide Klappen 4 und 5 etwa in der Ebene der Trennwand 3 liegen (vgL Abb. 3), während bei geöffneter öffnung die Klappe 5 die Sammelleitung 1 verschließt und die Klappe 4 etwa bis zur Mitte in die andere Sammelleitung 2 einschwenkt (vgl. A b b. 3, strichlierte Darstellung). Hierzu ist das Längenverhältnis der Hebel 24 und 25 zu 2 :1 gewählt, wobei der Hebel 25 im Bereich des Verbindungsbolzens ein Langloch 27 aufweistAt the shaft journals 22 and 23 of the pivot axes 6 and 8 act on levers 24 and 25, which have a common Actuate connecting bolt 26 «. The lever which forms the actuating element for the first flap 5 25 is coupled in this way to the lever 24 which forms the actuating element for the second pivoting flap 4 that when the opening is closed, both flaps 4 and 5 are approximately in the plane of the partition 3 (see Fig. 3), while when the opening is open, the flap 5 closes the collecting line 1 and the flap 4 closes approximately up to The middle swivels into the other collecting line 2 (cf. A b b. 3, dashed illustration). To do this is the aspect ratio the lever 24 and 25 selected to 2: 1, the lever 25 in the area of the connecting bolt Has elongated hole 27
