Description
Die Erfindung betrifft ein, selbsttätig durch Strömungsdruck sich öffnendes und durch Federkraft sich schließendes Ventil, insbesondere für Luftpumpen, dessen Ventilplatte außen durch drei an einem Ringkörper angebrachte, über den Umfang verteilte Stege geführt wird.The invention relates to a self-acting flow pressure valve that opens and closes by spring force, especially for air pumps, whose valve plate is attached to the outside by three on an annular body, over the circumference distributed webs is performed.
Bei den bekannten Ventilen dieser Bauart ermöglicht die Ausbildung des Ringkörpers das seitliche Abströmen des durch das Ventil strömenden Mediums unmittelbar oberhalb des Ventilsitzes. Hierdurch treten Kräfte auf, die die Ventilplatte in radialer Richtung zu verschieben suchen. Diese Kräfte führen mit der Zeit dazu, daß die Ventilplatte eckt und sich dann Ventilstörungen ergeben. Zur Verringerung der genannten seitlichen Kräfte hat man es schon für nötig befunden, eine besondere Leitwand in das Pumpengehäuse einzugießen.In the known valves of this type, the training allows of the ring body, the lateral outflow of the medium flowing through the valve immediately above the valve seat. This creates forces that affect the valve plate seek to move in the radial direction. Over time, these forces lead to that the valve plate corners and then valve malfunctions result. To reduce of the lateral forces mentioned, it has already been found necessary, a special one Pour the guide wall into the pump housing.
Nach der Erfindung schließt sich der Ringkörper unmittelbar an den Ventilsitzkörper an, und die Stege ,gehen in Haken über, die die Ventilfeder halten. Beim neuen Ventil wird die Strömung oberhalb des. Ventilsitzes zunächst in axialer Richtung weitergeleitet. Infolgedessen treten keine Kräfte auf, die die Ventilplatte in radialer Richtung zu verschieben suchen. Dadurch, daß die die Ventilfeder haltenden Haken an derselben Stelle sitzen, wo sich auch die Stege befinden, tritt durch die Haken keine zusätzliche Unterbrechung der Strömung auf. Das neue Ventil hat .daher einen günstigen hydraulischen Wirkungsgrad. Die erwähnte eingegossene Leitfläche wird überflüssig, so daß das Gußstück vereinfacht wird.According to the invention, the ring body connects directly to the Valve seat body on, and the webs go into hooks that hold the valve spring. With the new valve, the flow above the valve seat is initially axial Direction forwarded. As a result, there are no forces that affect the valve plate seek to move in the radial direction. By the fact that the holding the valve spring The hook sits in the same place where the webs are located, occurs through the Do not add any additional interruptions to the flow. The new valve has .therefore favorable hydraulic efficiency. The mentioned cast-in guide surface becomes unnecessary, so that the casting is simplified.
Die Erfindung besteht weiterhin in .der Anordnung des Ventils derart, daß sein Ventilsitz bei verkehrtem Einbau des Ventils gegen einen am Pumpenzylinder angegossenen Zäpfen trifft, bevor er in seine Führung im Pumpengehäuse einschnäbelt. Der am Pumpenzylinder angegossene Zapfen dringt in den Raum zwischen den hakenförmigen Stegen ein. Hierdurch werden die schroffen übergänge in den verschieden großen Strömungsquerschnitten gemildert, so daß die sonst bestehende turbulente Strömung weitgehend in eine laminare Strömung umgewandelt wird. Dies trägt dazu bei, das Ansetzen von Fremdkörpern an den Ventilteilen zu verhindern.The invention also consists in the arrangement of the valve in such a way that that if the valve is installed the wrong way, its valve seat is against one on the pump cylinder cast cones before it snaps into its guide in the pump housing. The pin cast on the pump cylinder penetrates the space between the hook-shaped ones Webbing. This creates the sharp transitions in the different sized flow cross-sections mitigated so that the otherwise existing turbulent flow largely in a laminar Flow is converted. This helps prevent foreign bodies from attaching to prevent the valve parts.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes und: seine Anordnung .dargestellt, und zwar zeigt Fig. i einen senkrechten Mittelschnitt des Ventils, Fig. 2 .einen senkrechten Mittelschnitt des Ventilsitzkörpers mit durch strichpunktierte Linien angedeuteter Form des Ventilsitzkörper-Rohlings und Fig. 3 de Anordnung .des neuen Ventils.The drawing shows an embodiment of the subject matter of the invention and: its arrangement .shown, namely Fig. i shows a vertical center section of the valve, Fig. 2. A vertical center section of the valve seat body with through Dash-dotted lines of the shape of the valve seat body blank and Fig. 3 de location of the new valve.
Das gezeichnete Ventil -setzt sich zusammen aus .dem Ventilsitzkörper i 'mit den Stegen 8, der Ventilplatte a, der Ventilfeder 3 und dem Ringkörper 4.. Beim Schlagen im Gesenk erhält der Ventilkörper an, seiner die Sitzfläche bildenden Seite den Boden 7. Dieser wird zusammen mit der Sitzfläche 6 auf der Drehbank. abgedreht. An einer Seite des Ventilsitzkörpers ist das Gewindesackloch 9 angeordnet, in das eine Handschraube eingedreht werden kann, mittels deren der Ventilsitzkörper von Druckventilen aus dem Pumpengehäuse herausgenommen werden kann.The drawn valve is composed of the valve seat body i 'with the webs 8, the valve plate a, the valve spring 3 and the annular body 4 .. When it hits the die, the valve body comes into contact with the one that forms the seat Side the floor 7. This is together with the seat 6 on the lathe. turned off. The threaded blind hole 9 is arranged on one side of the valve seat body, into which a hand screw can be screwed in, by means of which the valve seat body of Pressure valves can be removed from the pump housing.
Zur Führung .der Ventilplatte dient der Ringkörper 4 mit drei an ihm angebrachten, über den Umfang verteilten Stegen. Die Stege gehen in Haken über, die die Ventilfeder 3 halten. Der Ringkörper 4 schließt sich unmittelbar an den Ventilsitzkörper i an.The ring body 4 with three on it is used to guide the valve plate attached, over the circumference distributed webs. The bridges merge into hooks, which hold the valve spring 3. The ring body 4 connects directly to the Valve seat body i.
In den Zylinder ii ist ein Zapfen i2 ,eingegossen, der zentral in das Ventil hineinragt und .dicht vor dem Ventilsitzkörper i endigt. Würde man das Ventil verkehrt einbauen wollen, so würde der Zapfen 12 gegen den Ventilsitzkörper anstoßen, bevor das Ventil in seine Führung 13 im Pumpengehäuse einschnäbelt.In the cylinder ii, a pin i2 is cast, which is centrally located in the valve protrudes and ends tightly in front of the valve seat body i. You would Want to install the valve the wrong way round, the pin 12 would be against the valve seat body before the valve snaps into its guide 13 in the pump housing.
