Abstract

To minimise the flow resistance of a valve for large diameter tubes, the valve disc is laterally retracted so that no cross sectional restriction resists the flow. The valve spindle to which the valve disc is attached has the form of a semi-circular arch. It is located in a curved external housing so that a worm attached to a handwheel shaft, is in mesh with the teeth on the outside curve of the valve spindle. The inside of the valve and the valve disc are coated with an anti-corrosion layer. The valve spindle section inside the valve is protected by a bellow.

Die Erfindung betrifft ein Freifluftventil- oder VollstroiTiventil. Derartige Ventile werden als Absperrventile für die verschiedensten Zwecke verwendet. Insbesondere in der chemischen Industrie müssen sie in der Lage sein, Kolonnen Türme usw. abzusperren, im geöffneten Zustand sollen sie jedoch möglichst keinen liderstand bieten. Medien wie Gasen und Flüssigkeiten, die mit verhältnismäßig geringem Druck gefördert werden sollen, z. B. Absorptions- und Destillieranlagen, Abwasserleitungen mit geringem Gefälle, stehen nur geringe Vordrucke zur Verfügung, so daß möglichst keine Widerstände durch Absperrventile auftreten dürfen. Gleichzeitig besteht jedoch 'die Forderung, diese Anlagen gasdicht abschließen zu können, um bei Druckanstieg die nachgeschalteten Geräte, die oft aus Glas bestehen, zu schützen.The invention relates to a free air valve or Full flow valve. Such valves are used as shut-off valves for a wide variety of purposes used. In the chemical industry in particular, they must be able to handle columns Lock towers etc. when open however, if possible, they should not offer any resistance. Media such as gases and liquids, which are to be promoted with relatively low pressure, z. B. Absorption and distillation systems, Sewer pipes with a slight gradient, only small forms are available, so that as far as possible no resistance from shut-off valves may occur. At the same time, however, there is the requirement that these systems To be able to seal gas-tight in order to prevent the downstream devices that often made of glass to protect.

Bekannt sind Ventile mit Klappen oder Membranen, die jedoch, insbesondere bei großen Nennweiten, noch einen zu großen Durchflußwiderstand leisten. Auch können die bekannten Freiflußventile nur mit großem Kostenaufwand gegen hochaggressive Medien ausgekleidet werden.Valves with flaps or membranes are known, which, however, especially in the case of large Nominal sizes, still provide too great a flow resistance. The known free-flow valves can only be lined against highly aggressive media at great expense.

Die Aufgabe der Erfindung besteht darin, ein Freiflußventil zu schaffen, das - selbst bei großen Nennweiten - einen kleineren Widerstand bietet, als die bisher bekannten Ventile, und das eine Auskleidung herkömmlicher V/eise gegen aggressive Medien ermöglicht.The object of the invention is to create a free-flow valve that - even with large nominal sizes - offers a smaller resistance than the previously known valves, and that enables conventional V / iron to be lined against aggressive media.

Diese Aufgabe wird erfindungsgemäß bei einem Freiflußventil mit einem quer im Ventilgehäuse angeordneten kegeligen. Ventil-Sitzring, sowie einem an einer Ventilspindel gelagerten Ventilteller dadurch gelöst, daß die Ventilspindel konstant gekrümmt ist, in einer seitlich der Gehäuselängsachse angeordneten, entsprechend gekrümmten Führung verschiebbar gelagert ist und an ihrem Ende auf der Außenseite eine Verzahnung trägt, in die eine Antriebsschnecke eingreift, welche als Ventilantrieb die Spindel kreisbogenförmig bewegt. Auf diese Weise kann der Ventilteller völlig aus dem Bereich des strömenden Mediums herausgeschwenkt werden. This object is achieved according to the invention in a free-flow valve with a transverse in the valve housing arranged conical. Valve seat ring, as well as a valve disk mounted on a valve spindle solved in that the valve spindle is constantly curved, in a side of the Housing longitudinal axis arranged, correspondingly curved guide is slidably mounted and at its end on the outside carries a toothing into which a drive worm engages, which acts as a valve drive and moves the spindle in a circular arc. In this way the valve disk can be swiveled completely out of the area of the flowing medium.

Ein Ausführungsbeispiel eines Ventils nach der Erfindung ist in der Zeichnung schematisch dargestellt.An embodiment of a valve according to the invention is shown in the drawing shown schematically.

Darin ist ein, im wesentlichen übliches, T-fö'rmiges Ventilgehäuse mit 1 bezeichnet. Es besitzt eine korrosionsfeste Auskleidung 2. Ein Ventil-Sitzring 3 und ein Ventilteller k mit einem korrosionssicheren Überzug 5 unterscheiden sich ebenfalls praktisch nicht von der sonst üblichen Bauart. Der Ventilteller k ist auf einen Gewindezapfen 6 einer konstant gekrümmten Ventilspindel 7 aufgeschraubt. Die Spindel 7 ist in einer seitlich der Gehäuselängsachse angeordneten, entsprechend gekrümmten Führung 8 verschiebbar gelagert. Am äußeren Ende trägt die Spindel auf ihrer Außenseite eine Verzahnung 9 in die eine Antriebsschnecke 10 eingreift. Durch Drehen eines Handrades 11 wird die Spindel kreisbogenförmig bewegt. Der Ventilteller A- gelangt auf diese Weise in die gestrichelt eingezeichnete Offenstellung.An essentially customary T-shaped valve housing is denoted by 1 therein. It has a corrosion-resistant lining 2. A valve seat ring 3 and a valve disk k with a corrosion-proof coating 5 likewise practically do not differ from the otherwise customary design. The valve disk k is screwed onto a threaded pin 6 of a constantly curved valve spindle 7. The spindle 7 is slidably mounted in a correspondingly curved guide 8 which is arranged to the side of the longitudinal axis of the housing. At the outer end of the spindle has a toothing 9 on its outside, into which a drive worm 10 engages. By turning a handwheel 11, the spindle is moved in a circular arc. The valve disk A- arrives in this way in the open position shown in dashed lines.

Der dem Medium ausgesetzte Teil der Spindel ist durch einen Faltenbalg 12 gegen Korrosion geschützt.The part of the spindle exposed to the medium is protected against corrosion by a bellows 12 protected.

Der Spindelquerschnitt kann rund, rechteckig oder quadratisch, sein. Die Länge der Ventilführung, gegebenenfalls nur in wenigen Bereichen, wird den Bedürfnissen angepaßt. Die Ventilfuhrung 8 ist bei dem dargestellten Ausführungsbeispiel zwar mit dem Gehäusedeckel 13 und der Lagerung der Antriebsschnecke 10 einteilig, dies ist jedoch nicht erforderlich. Auch die Betätigung der Spindel kann auf einem anderen, als dem dargestellten Wege erfolgen, gegebenenfalls auch elektrisch, hydraulisch oder pneumatisch.The spindle cross-section can be round, rectangular or square. The length of the valve guide, if necessary only in a few areas, is adapted to the needs. The valve guide 8 is in the illustrated embodiment with the housing cover 13 and the mounting of the drive worm 10 in one piece, but this is not necessary. The spindle can also be operated in a different way than the one shown, if necessary also electrically, hydraulically or pneumatically.
