Abstract

The non-return valve has several valve passages each contg. a ball (2) closure member. The passages are arranged in parallel in a common housing and each take a part of the flow through the assembly. The valve is especially for large flow dias. e.g. diameters > 1.5. inch and avoids weight area problems associated with relatively large balls. The passages may be provided in two coaxial generally cylindrical components (1, 3). In one of the components the passages are widened to receive the respective balls. In the other component the ends of the passages define seat (4) for the balls.

KugelrückschlagventilBall check valve

Die Erfindung betrifft ein Kugelrückschlagventil für größere Durchmesser.The invention relates to a ball check valve for larger diameters.

Die bekannten Kugelrückschlagventile sind unempfindlich gegen Verschmutzung und gegen Verklemmen der Kugel. Auch gibt es keine eingeschlagenen Dichtrillen9 da stets eine andere Stelle der Kugeloberfläche gegen den Sitz abdichtet. Es ist auf Grund seiner Schließ- und Dichteigenschaften besser als andere Ventile geeignet, auch zum Verpumpen von dickflüssigen Medien. Das mit zunehmender Kugelgröße ungünstiger werdende Gewichts/ Flächenverhältnis begrenzt jedoch den Einsatz der Kugelrückschlagventile .The known ball check valves are insensitive to contamination and to jamming of the ball. There are also no stamped-in sealing grooves 9 since there is always a different point on the spherical surface sealing against the seat. Due to its closing and sealing properties, it is better suited than other valves, also for pumping viscous media. However, the weight / area ratio, which becomes more unfavorable with increasing ball size, limits the use of ball check valves.

Daher werden bei größeren Nennweiten ein- oder zweiseitig geführte Kegelventile eingesetzt und Plattenventile. Diese Ventile sind immer federbelastet. Sie sind in den vorgenannten Punkten den Kugelrückschlagventilen zumeist unterlegen. Ein Nachteil des Kegelventils ist auch die starke Geräuschentwicklung. Therefore, in the larger N e nnweiten one or both sides guided plug valves used and plate valves. These valves are always spring loaded. They are mostly inferior to ball check valves in the aforementioned points. Another disadvantage of the cone valve is that it generates a lot of noise.

Es ist Aufgabe der Erfindung, ein Kugelrückschlagventil zu schaffen, das bei größeren Nennweiten ein günstiges Flächen/ Gewichtsverhältnis hat.It is the object of the invention to create a ball check valve that has a favorable surface area / Has weight ratio.

Erfindungsgemäß wird vorgeschlagen, mehrere Ventileinheiten bestehend aus Kugel und Ventilsitz so anzuordnen, daß jede Ventileinheit nur von einem Teil des Medienstromes durchströmt wird. Der Gesamtquerschnitt der Kugelventile entspricht dabei dem Sollventilquerschnitt.According to the invention it is proposed to arrange several valve units consisting of ball and valve seat so that each valve unit only part of the media flow flows through it. The total cross-section of the ball valves corresponds to the target valve cross-section.

In Fig. 1 ist ein Ausführungsbeispiel der Erfindung dargestellt. Es handelt sich um eine Gruppe von drei in einer Ebene liegenden Kugelventilen. Der Gesamtquerschnitt der drei Kugelventile entspricht dem Querschnitt eines üblicherweise eingesetzten Kegel- oder Plattenventils. Die Kugel 2 verhindert das Zurückströmen des in Pfeilrichtung fließenden Medienstromes, der sich zu gleichen Teilen auf die 3 Ventileinheiten verteilt.In Fig. 1, an embodiment of the invention is shown. It is a group of three ball valves lying in one plane. The total cross-section of the three ball valves corresponds to the cross section of a commonly used cone or plate valve. The ball 2 prevents the flow back of the media flow flowing in the direction of the arrow, which is distributed equally over the 3 valve units.

Die drei Dichtsitze 4 sind in einer Ebene im Sitzteil 3 angeordnet. Im Käfig 1 wird der Weg der Kugeln 2 auf bekannte Art begrenzt.The three sealing seats 4 are arranged in one plane in the seat part 3. In the cage 1, the path of the balls 2 is limited in a known manner.

Fig. 2 zeigt die Draufsicht auf das Sitzteil 3 des Ausführungsbeispiels. Fig. 2 shows the plan view of the seat part 3 of the embodiment.

Ab einer Nennweite von 1 1/2" kann die Erfindung besonders vorteilhaft eingesetzt werden. Ein Prototyp, der nach dem Prinzip der Fig. 1 ausgeführt wurde, war 4000 Betriebsstunden zum Verpumpen von 200°C heißem Glykol eingesetzt und zeigte keinen Verschleiß. Darüber hinaus lief die mit diesem Ventil ausgerüstete Kolbenpumpe mit einem um 15 bis 20 dBa geringeren Geräuschpegel als die mit der Originalventilbestückung mit Kegelventilen ausgerüsteten Pumpe, die mit 90 dBa lief.From a nominal diameter of 1 1/2 ", the invention can be particularly advantageous can be used. A prototype, which was carried out according to the principle of FIG. 1, was 4000 operating hours for pumping of 200 ° C hot glycol and showed no wear. In addition, the one equipped with this valve ran Piston pump with a noise level 15 to 20 dBa lower than that with the original valve assembly with cone valves equipped pump that ran at 90 dBa.
