Description
Dreiwegeventil mit zwei Verschlußstücken und Druckmittelantrieb, insbesondere Dampf-Wasser-Ventil für Schallplattenpressen Die Erfindung bezieht sich auf ein Dreiwegeventil mit zwei Verschlußstücken, die mit je einem Sitz zusammenarbeiten und durch je einen durch eine Stange mit dem Verschlußstück verbundenen, in einem Zy- linder abgedichtet gleitenden Kolben durch Druckbeaufschlagung betätigt werden, mit konzentrischer Ineinanderanordnung der Stangen und mit einer derartigen Druckbeaufschlagung der Kolben, daß das eine Verschlußstück schließt, bevor das andere öffnet.Three-way valve with two closing pieces and pressure fluid drive, in particular steam-water valve for records pressing The invention relates to a three-way valve with two closing pieces, which cooperate each with a seat and connected by a respective through a rod with the closure piece, sealed in a ZY linder sliding pistons are pressurized with the rods nested concentrically and the pistons being pressurized such that one closure closes before the other opens.
Die Erfindung löst die Aufgabe einer einfacheren Ausbildung eines solchen Ventils, das auch für zwei Arbeitsmedien, nömlich Wasser und Dampf, eingesetzt werden kann.The invention solves the problem of a simpler training such a valve, which is also used for two working media, namely water and steam can be.
Die Lösung dieser Aufgabe erfolgt durch die gleichzeitige Anwendung folgender an sich bekannter Merkmale: a) Die beiden Kolben (14, 15) gleiten in einem gemeinsamen glatten Zylinder (16) unter Bildung von zwei Druckkammern (17, 18), b) sie werden durch eine Feder (19) auseinandergedrückt, und c) die Druckbeaufschlagung erfolgt nur auf die Außenseiten der beiden Kolben (14, 15). This object is achieved by the simultaneous use of the following known features: a) The two pistons (14, 15) slide in a common smooth cylinder (16) forming two pressure chambers (17, 18), b) they are through a spring (19) is pushed apart, and c) the pressure is only applied to the outer sides of the two pistons (14, 15).
Die beanspruchten Merkmale a) und b) dienen b6i einer bekannten Ausführung einem anderen Zweck, nämlich einem Schnellschluß; ferner ist ein druckmittelbetätigtes Absperrventil bekannt, bei dem der einzige Kolben beidseitig in einem glatten Zylinder beaufschlagt wird.The claimed features a) and b) serve b6i a known embodiment for a different purpose, namely a quick release; Furthermore, a pressure-actuated shut-off valve is known in which the single piston is acted upon on both sides in a smooth cylinder.
Als Ausführungsbeispiel nach der Erfindung ist in den Figuren schematisch ein Dampf-Wasser-Ventil dargestellt worden. Im geschlossenen Zustand (F i g. 1) strömt weder Dampf noch Wasser durch das Ventil in die Leitung.As an embodiment according to the invention, a steam-water valve has been shown schematically in the figures. In the closed state ( FIG. 1) , neither steam nor water flows through the valve into the line.
In der in F i g. 2 gezeigten Stellung des Ventils strömt nur Dampf durch das Ventil in die Zuleitung zur Preßform, und F i g. 3 gibt die Stellung des Ventils wieder, bei der nur Wasser durch das Ventil strömt und der Dampf abgesperrt ist.In the in F i g. The position of the valve shown in FIG. 2 only flows steam through the valve into the feed line to the mold, and FIG . 3 shows the position of the valve in which only water flows through the valve and the steam is shut off.
Das Ventil besteht aus dem Ventilgehäuse 11, das die Ventilkammer 10 enthält und von dem die Ab- leitungen 5 zur Preßform der Presse abgehen. Die Ventilkammer ist mit Sitzen 6, 7 versehen, durch die der Ventilkammer Dampf oder Wasser über die Verschlußstücke 9, 8 von den Zuleitungen 3, 4 zugeführt werden kann. Der Antrieb der Verschlußstücke erfolgt mittels Druckluft. Dazu sitzen die Verschlußstücke 9, 8 der Ventile auf Stangen 12, 13, an deren Enden Kolben 14, 15 ausgebildet sind. Die Stangen sind konzentrisch angeordnet. Zwischen den Kolben 14, 15 im Zylinder 16 ist eine Druckfeder 19 angeordnet, welche die beiden Kolben auseinandertreibt und dadurch bewirkt, daß beide Verschlußstücke die Sitze abschließen (Stellung F i g. 1). The valve consists of the valve housing 11 containing the valve chamber 10 and from which the exhaust pipes 5 to come off the press die. The valve chamber is provided with seats 6, 7 through which steam or water can be supplied to the valve chamber via the closure pieces 9, 8 from the supply lines 3, 4. The closure pieces are driven by means of compressed air. For this purpose, the closing pieces 9, 8 of the valves sit on rods 12, 13, at the ends of which pistons 14, 15 are formed. The rods are arranged concentrically. A compression spring 19 is arranged between the pistons 14, 15 in the cylinder 16 , which drives the two pistons apart and thereby causes the two locking pieces to close the seats (position FIG. 1).
Wird nun in die Druckkammer 17 über die Zuleitung 2 Druckluft eingelassen, dann öffnet beim Hochdrücken des Kolbens 15 das Dampfventil durch Abheben des Verschlußstücks 9. Das Verschlußstück 8 wird durch die zwischen den Kolben zusammengedrückte Feder noch stärker gegen den Sitz 6 für die Wasserzuleitung gedrückt und sperrt die Wasserzufuhr ab, so daß nur Dampf über die Zuleitung in die Ableitung 5 strömt (Stellung F i g. 2).If compressed air is now admitted into the pressure chamber 17 via the supply line 2, when the piston 15 is pushed up, the steam valve opens by lifting the closure piece 9. The closure piece 8 is pressed even more strongly against the seat 6 for the water supply by the spring compressed between the piston and blocks the water supply so that only steam flows through the supply line into the discharge line 5 (position F i g. 2).
Beim Umschalten von Wasser auf Dampf wird die Zuleitung 2 entlüftet, die Druckkammer 17 wird drucklos, und das Verschlußstück 9 schließt. Durch die Zuleitung 1 wird dann die Druckkammer 18 mit Druckluft versorgt, so gaß dadurch der Kolben 14 herabgedrückt und das Verschlußstück 8 vom Sitz 6 für Wasser abgehoben wird, so daß durch die Zuleitung 4 Wasser in die Ableitung 5 strömen kann. In dieser Stellung wird das Verschlußstück 9 verstärkt gegen den Sitz 7 für Dampf gezogen und damit der Dampf abgesperrt (Stellung F i g. 3). When switching from water to steam, the supply line 2 is vented, the pressure chamber 17 is depressurized, and the closure piece 9 closes. The pressure chamber 18 is then supplied with compressed air through the supply line 1 , so that the piston 14 gas is pressed down and the closure piece 8 is lifted from the seat 6 for water, so that water can flow through the supply line 4 into the discharge line 5. In this position, the closure piece 9 is increasingly pulled against the seat 7 for steam and thus the steam is shut off (position FIG. 3).
