Description

Selbsttätiges Absperrorgan für strömende Medien, dessen Absperrflächen durch Magnetismus aufeinandergepreßt werden Die Erfindung bezieht sich auf solche Absperrorgane in Rohrleitungen für strömende Medien, die nicht von Hand betätigt werden.Automatic shut-off device for flowing media, its shut-off surfaces are pressed together by magnetism. The invention relates to such Shut-off devices in pipelines for flowing media that are not operated by hand will.

Bekanntlich versteht man unter Absperrorganen Einrichtungen, die den Durchfluß eines Mediums in einer Leitung wahlweise verhindern oder gestatten.As is well known, shut-off devices are understood to mean that the Optionally prevent or allow the flow of a medium in a line.

Zu den nicht von Hand betätigten Organen gehören Diruckminderer, Sicherheitsventile, Rückschlageinrichtungen, wie Rückschlagteller, -platten, -kugeln, -kegel u. ä. Derartige Organe wirken durch ihr Eigengewicht, zum Teil in Verbindung mit Federdruck oder Zusatzgewicht. Je nach Größe des Eigengewichts und der verwendeten sonstigen Belastung ist ein mehr oder minder hoher Anfangsdruck erforderlich, um den D;urchflußvorgang einzuleiten, und wird umgekehrt bei Unterschreiten eines 'bestimmten Drucks die Durchströmbewegung abgeschnitten. Je nach Bauart und Verwendungszweck ist der öffnungs- und Schließdruck gleich oder verschieden.The organs that are not operated by hand include pressure reducers, safety valves, Non-return devices such as non-return plates, plates, balls, cones and the like Organs work by their own weight, partly in connection with spring pressure or Additional weight. Depending on the size of the dead weight and the other loads used a more or less high initial pressure is required to start the flow process initiate, and is reversed when falling below a 'certain pressure the Cut off flow movement. Depending on the type and purpose of use, the opening and closing pressure the same or different.

Derartigen Einrichtungen haften Mängel an, die bei manchen Verwendungszwecken hinderlich in Erscheinung treten. Es sind dies -u. a. die Störung des Arbeitsvorganges durch Verschmutzung bei innenliegender Feder, der Zwang zur Einhaltung unerwünschter Abmessungen im Hinblick auf die außen- Moder innenliegenden Federn oder Gewichte oder auch die Ungleichförmigkeit des eingestellten DTUcks in Abhängigkeit vom Hub des Organs und damit in Abhängigkeit von der Durchflußm-enge je Zeiteinheit.Such facilities are liable to deficiencies in some uses appear in an obstructive manner. These are -u. a. the disruption of the work process due to contamination with internal spring, the compulsion to comply is undesirable Dimensions with regard to the external moder internal springs or weights or the irregularity of the set DTUck depending on the stroke of the organ and thus depending on the flow rate Time unit.

Ebenso ist es schwierig, rein mechanisch irgendwelche ganz bestimmten, irgendwie geforderten Abhängigkeiten zwischen strömendem Medium und dem sich einstellenden Diruck, z. B. von irgendeiner zeitlichen Funktion oder einer solchen der Durchflußme,nge, herzustellen.It is also difficult to mechanically identify any very specific, somehow required dependencies between the flowing medium and the emerging Diruck, e.g. B. of some temporal function or one of the flow rate, to manufacture.

Dier Erfindung liegt die Aufgabe zugrunde, diese Nachbeile zu beseitigen und ein Absperrorgan zu entwickeln, .das unempfindlich gegen Verschmutzung und unabhängig von Rückstellkräften ist, dabei aber eine möglichst große Freiheit in der Wahl der baulichen Abmessungen gestattet.The invention is based on the object of eliminating these disadvantages and to develop a shut-off device that is insensitive to pollution and independent of restoring forces, but the greatest possible freedom in the choice of structural dimensions permitted.

Erfindungsgemäß wird daher die Aufeina.nderfügung der dichtenden Flächen durch Magnetismus vorgenommen. Der Anpreßdruck ist neben dem lagebedingten Eigengewicht des Absperrorgans abhängig von der Größe der verwendeten Absperrteile und dem Grade ihrer magnetischen Sättigung. Sowohl die festen wie die beweglichen Teile des Absperrorgans können hieran Anteil haben.According to the invention, therefore, the assembly of the sealing surfaces made by magnetism. The contact pressure is next to the position-related dead weight of the shut-off device depending on the size of the shut-off parts used and the degree their magnetic saturation. Both the fixed and the moving parts of the shut-off device can participate in this.

Der Magnetismus kann ebenso auf Verwendung permanenter Magnete beruhen wie auf der Anwendung von Elektrizität.The magnetism can also be based on the use of permanent magnets as on the application of electricity.

Im folgenden sind Ausführungsbeispiele der Erfindung unter Bezugnahme auf die Zeichnungen näher beschrieben. Gleiche Teile haben in den Abbildungen gleiche Ziffern. i. Einfaches Rückschlagventil mit permanentem Magnet In dem Ventilkörper i aus nichtmagnetischem Werkstoff befindet sich eine Rückschlagkugel 2, die auf einem magnetischen Sitzkörper 3 ruht. Je nach dem geforderten Öffnungsdruck richtet sich die permanentmagnetische Sättigung von Kugel und,!oder Sitz sowie die Größe des Sitzkörpers. Um dessen Größe je nach den Anforderungen variieren zu können, ist eine entsprechend variable Zwischenbüchse 4 vorgesehen. Ein zu großer Hub wird durch den Begrenzungsstift 5 vermieden.In the following, exemplary embodiments of the invention are described in more detail with reference to the drawings. The same parts have the same numbers in the illustrations. i. Simple non-return valve with permanent magnet In the valve body i made of non-magnetic material there is a non-return ball 2 which rests on a magnetic seat body 3. The permanent magnetic saturation of the ball and,! Or seat as well as the size of the seat body depends on the required opening pressure. In order to be able to vary its size depending on the requirements, a correspondingly variable intermediate sleeve 4 is provided. Too long a stroke is avoided by the limiting pin 5.

2. Einfaches Rückschlagventil mit Elektromagnet Der Aufbau ist im Prinzip der gleiche wie unter Beispiel i, nur wird an Stelle des permanentmagnetischen Sitzkörpers 3 ein elektrisch magnetisierbarer verwendet. Er ist hier mit 6 bezeichnet. Um den Sitzteil des Ventilkörpers liegt eine Spule 7. Je nach ihrer Erregung richtet sich der öFfnungs-und Schließdruck; ein von beliebigen Faktoren hestimmhares Arbeitsprogramm ist möglich.2. Simple check valve with electromagnet. The structure is in Principle is the same as in example i, but instead of the permanent magnet Seat body 3 used an electrically magnetizable. It is denoted by 6 here. A coil 7 is located around the seat part of the valve body the opening and closing pressure; a program of work determined by any factors is possible.

3. Ventil mit Elektromagnet Der Aufbau ist im Prinzip der gleiche wie unter Beispiel 2, nur ist hier ein Öffnungsstift 8 mit einer zugehörigen weiteren Spule g vorgesehen. Auch hier ist der öffnungs- und Schließdruck durch die Erregung der Spulen regelbar; ein von beliebigen Faktoren bestimmbares Arbeitsprogramm ist möglich.3. Valve with electromagnet The structure is basically the same as in example 2, only here is an opening pin 8 with an associated additional one Coil g provided. Again, the opening and closing pressure is due to the excitation the coils adjustable; is a work program that can be determined by any factors possible.
