Description
Absperrschieber Zusatz zum Patent q.go 816 Bei den Absperrschiebern nach dem Patent 490 816 ist nur der untere, im Gehäuse sitzende Andruckkeil verstellbar eingerichtet, während die beiden oberen seitlichen Keile feststehend angeordnet sind. Es hat sich nun gezeigt, daß, wenn die beiden oberen Keile gleichzeitig und beiderseitig zum Anliegen an die Keilplatten kommen sollen, ein großer Genauigkeitsgrad in der Bearbeitung erforderlich wird.Gate valve Addition to patent q.go 816 For gate valves according to the patent 490 816 only the lower pressure wedge seated in the housing is adjustable set up, while the two upper side wedges are fixed are. It has now been shown that when the two upper wedges simultaneously and Both sides should come into contact with the wedge plates, a high degree of accuracy becomes necessary in the processing.
Um diesem Übelstand abzuhelfen, wurden nach der Anordnung, die den Gegenstand der vorliegenden Erfindung bildet, die beiden oberen Andruckkeile im Gehäuse so angeordnet, daß dieselben mit Zapfen oder zapfartigen Teilen um Achsen drehbar sind, die zur Verbindungslinie der beiden Keilflächen parallel liegen. Zu diesem Zwecke sind die Keilstücke mit einem Bund in dem Gehäuse gelagert und stützen sich des ferneren mit ihrer unteren zylindrischen Fläche auf ebene Tragflächen des Gehäuses.In order to remedy this problem, according to the order that the The present invention forms the two upper pressure wedges in the Housing arranged so that the same with pins or pin-like parts around axes are rotatable, which are parallel to the connecting line of the two wedge surfaces. to For this purpose, the wedge pieces are mounted and supported with a collar in the housing moreover, with their lower cylindrical surface on the flat bearing surfaces of the Housing.
Durch diese Anordnung wird erreicht, daß bei der Berührung mit den entsprechenden Keilnocken der Abschlußplatten die Andruckkeile sich selbsttätig so einstellen können, daß das Anliegen an die Keilnocken beiderseitig gleichmäßig erfolgt.This arrangement ensures that when in contact with the corresponding wedge cams of the end plates the pressure wedges automatically can be adjusted so that the contact with the wedge cam is uniform on both sides he follows.
Zu dem gleichen Zwecke ist den Keilen auch eine beschränkte seitliche Verschiebungsmöglichkeit belassen.For the same purpose, the wedges are also limited to the side Leave the possibility of shifting.
Auf der Zeichnung ist ein Ausführungsbeispiel eines solchen Absperrschiebers dargestellt worden, und zwar zeigt Abb. z einen senkrechten Längsschnitt durch den Absperrschieber, während Abb. a einen senkrechten Schnitt nach der Ebene A-B der Abb. x zeigt.The drawing shows an embodiment of such a gate valve has been shown, namely Fig. Z shows a vertical longitudinal section through the Gate valve, while Fig. A is a vertical section along the plane A-B of the Fig.x shows.
An dem Gehäuse a sind unterhalb der beiden seitlichen Andruckkeile zwei Rippen b und c angegossen. Auf der oberen ebenen Fläche dieser Rippen ruht die untere abgerundete Fläche der beiden Keile d und e, derart, daß diese darauf eine kurze rollende Bewegung ausführen können. Die Keile d und e treten mit seitlichem Spiel durch die Fenster f hindurch. Sie tragen an ihrer Außenseite einen Bund g, der in einer tellerförmigen Vertiefung des Gehäuses ebenfalls mit seitlichem Spiel gelagert ist. Der Zweck dieses seitlichen Spieles ist, den Keilen d und e gegebenenfalls eine kurze seitliche Verschiebung zu gestatten. Auf der äußeren Stirnfläche tragen die Keile d und e je einen Vierkant h, der mit Spiel in eine entsprechende vierkantige Vertiefung i der Deckel k eingreift, welche für den dichten Abschluß des Gehäuses an dieser Stelle sorgen. Dieser Vierkant A ist dazu bestimmt, eine zu starke Verdrehung der Keile d und e zu verhindern.Two ribs b and c are cast on the housing a below the two lateral pressure wedges. The lower rounded surface of the two wedges d and e rests on the upper flat surface of these ribs in such a way that they can perform a short rolling movement thereon. The wedges d and e pass through the window f with lateral play. They wear a collar g on their outside, which is also mounted with lateral play in a plate-shaped recess in the housing. The purpose of this lateral play is to allow the wedges d and e to move sideways if necessary. On the outer end face, the wedges d and e each have a square h which engages with play in a corresponding square recess i of the cover k , which ensures the tight closure of the housing at this point. This square A is designed to prevent the wedges d and e from twisting too much.
