Description

Vorliegende Erfindung betrifft einen Absperrschieber mit zwei parallelen Dichtungsflächen, bei welchem zwei Zahnstangen derart einander gegenüberliegend an zwei aufeinandergleitenden Schieberplatten angebracht sind, daß beide Platten durch ein einziges zwischen den Zahnstangen drehbar gelagertes Ritzel gegeneinander verschoben werden können. Die Schieberplatten sind zwecks besserer Abdichtung in der Schlußstellung in bekannter Weise keilförmig ausgebildet.The present invention relates to a gate valve with two parallel sealing surfaces, in which two toothed racks mounted opposite one another on two sliding plates are that both plates are rotatably supported by a single one between the racks Pinions can be moved against each other. The slide plates are better for the purpose Sealing in the final position is wedge-shaped in a known manner.

Absperrschieber, bei welchen zwei sich überdeckende und aufeinandergleitende Schieberplatten durch zwei Zahnstangen betätigt werden, skid bekannt. Jedoch sind hierbei die Zahnstangen so auf beiden Seiten des Absperrorgans angeordnet, daß zu ihrer Betätigung je ein Ritzel erforderlich ist. Diese Ritzel sind durch zwei Zahnsegmente bewegao lieh verbunden. Die bekannte Einrichtung an Absperrschiebern erfordert außerdem durch das vorhandene zweite Ritzel noch die Anbringung einer zweiten Stopfbüchsenabdichtung. Gate valve in which two overlapping and sliding gate valves operated by two racks, known as skid. However, here are the racks are arranged on both sides of the shut-off device so that they can be actuated one pinion each is required. These pinions can be moved by two tooth segments borrowed connected. The known device on gate valves also requires through the existing second pinion still needs to be fitted with a second gland seal.

Demgegenüber ist der Erfindungsgegenstand wesentlich einfacher, wobei hinzukommt, daß durch die günstige Anordnung der Zahnstangen in Verbindung mit den keilförmigen Schieberplatten es möglich ist, in der Schlußstellung die Schieberplatten fest an die Dichtungsringe anzupressen, ohne daß im Ritzellager Zugkräfte auftreten.In contrast, the subject of the invention is much simpler, with the addition of that by the favorable arrangement of the racks in connection with the wedge-shaped Slide plates it is possible, in the final position, to firmly attach the slide plates to the sealing rings pressed without tensile forces occurring in the pinion bearing.

Fig. ι und Fig. 2 zeigen den beschriebenen Absperrschieber in Querschnitt und Seitenschnitt. Fig. Ι and Fig. 2 show the gate valve described in cross section and side section.

Wie aus Fig. 1 und Fig. 2 ersichtlich, sind in dem Gehäuse <a zwei Schieberplatten b und Q beweglich gelagert. An diesen befestigt sind die Zahnstangen d und e, welche in das zwischen ihnen im Gehäuseköpf/ gelagerte Zahnritzel g eingreifen. Die Schieberplatten b und c sind keilförmig ausgebildet, so daß bei einer gegenläufigen Bewegung die parallelen Dichtungsflächen fest gegen die Dichtungsringe h und i gepreßt werden. Für den freien Durchgang bei geöffnetem Absperrschieber haben die Schieberplatten je eine Bohrung. Das Ritzel g wird durch den Hebel k betätigt. Zur Verminderung der Reibung können an den gegenseitigen Beruh- go rungsflächen der Schieberplatten Kugeln oder RoEen gelagert werden.As can be seen from Fig. 1 and Fig. 2, two slide plates b and Q are movably mounted in the housing <a. The toothed racks d and e, which engage in the pinion g mounted between them in the housing head / mounted between them, are attached to these. The slide plates b and c are wedge-shaped so that when they move in opposite directions, the parallel sealing surfaces are pressed firmly against the sealing rings h and i. The valve plates each have a hole for free passage when the gate valve is open. The pinion g is operated by the lever k . In order to reduce the friction, balls or tubes can be mounted on the mutual contact surfaces of the slide plates.
