Description

Entlastetes Magnetventil mit automatischer Federspannung Die Erfindung betrifft ein entlastetes Magnetventil mit einem mit dem Magnetanker verbundenen Verschlußstück und einer sich an einem Magnetführungsrohr abstützenden Rückstellfeder, die bei der magnetischen Betätigung des Ventils gespannt wird.Relieved solenoid valve with automatic spring tension The invention relates to a relieved solenoid valve with one connected to the solenoid armature Closure piece and a return spring supported on a magnet guide tube, which is tensioned when the valve is magnetically actuated.

Bei den bekannten druckentlasteten Magnetventilen arbeitet das Verschlußstück mit einer Rückstellfeder zusammen. Zur Betätigung des Verschlußstücks in beide Richtungen wird jeweils die gleiche Kraft benötigt, um den Reibungswiderstand der Abdichtmittel für die Druckentlastung und den Strömungswiderstand des Durchflußmittels zu überwinden. Die Rückstellfeder ist in beiden Endstellungen gespannt. Beim Betätigen des Ventils muß zusätzlich zur Reibung der Abdichtmittel und zum Widerstand des strömenden Durchflußmittels auch die Kraft der vorgespannten Feder vom Magneten überwunden und weitergespannt werden.In the known pressure-relieved solenoid valves, the closure piece works together with a return spring. To operate the locking piece in both directions the same force is required in each case to reduce the frictional resistance of the sealant for pressure relief and to overcome the flow resistance of the flow medium. The return spring is tensioned in both end positions. When actuating the valve must in addition to the friction of the sealing means and the resistance of the flowing fluid the force of the pretensioned spring was also overcome by the magnet and tensioned further will.

Bei einem anderen Ventil arbeitet das Verschlußstück mit zwei Magneten zusammen. Für jede Schaltstellung ist ein Magnet erforderlich.In another valve, the closing piece works with two magnets together. A magnet is required for each switch position.

Der große Nachteil dieser Ventile ist, daß entweder ein sehr großer oder aber zwei Magneten benötigt werden.The major disadvantage of these valves is that either one is very large or two magnets are required.

Aufgabe der Erfindung ist demgegenüber ein druckentlastetes Mehrzweckventil für alle Druckbereiche zu schaffen, bei dem die Magnetkraft verringert werden kann und das somit in seinen Abmessungen kleiner und billiger zu fertigen ist.In contrast, the object of the invention is a pressure-relieved multipurpose valve for all pressure areas where the magnetic force can be reduced and that is therefore smaller and cheaper to manufacture in terms of its dimensions.

Gemäß der Erfindung wird das dadurch erreicht, daß die Rückstellfeder durch einen an sich bekannten Kolben gespannt wird, der abgedichtet in den Magnetanker hineinragt und über einen an sich bekannten inneren Kanal des Magnetankers und des Verschlußstücks vom Ventileinlaß her mit Druckmittel beaufschlagt wird.According to the invention this is achieved in that the return spring is tensioned by a piston known per se, which is sealed into the magnet armature protrudes and via a known inner channel of the armature and the Closure piece is acted upon by pressure medium from the valve inlet.

Weitere Merkmale der Erfindung ergeben sich aus dem Unteranspruch.Further features of the invention emerge from the subclaim.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung, bei dem die Magnetspule spannungslos ist, dargestellt.In the drawing is an embodiment of the invention in which the solenoid is de-energized, shown.

Das Ventilgehäuse 1 hat eine Bohrung 19, in deren Mitte der Distanzring 21 festgesetzt ist. Die Ventileinsätze 20 werden ebenfalls von der Bohrung 19 aufgenommen und beiderseits vom Distanzring 21 gehalten. Durch die Abdichtmittel 3 und die am Verschlußstück 17, 17' zur Druckentlastung angebrachten Abdichtmittel4', 4" wird der Ventilinnenraum in drei Kammern 5, 6, 7 geteilt und jeweils eine Kammer mit einem Ventilanschluß, nämlich Kammer 5 mit Anschluß C, Kammer 6 mit Anschluß A und Kammer 7 mit Anschluß B, verbunden. Die Ventileinsätze 20 werden durch die Deckel 2 und 1.8 im Ventilgehäuse 1 gehalten. Der Deckel 18 hat einen Gewindeansatz 18', auf den das Magnetführungsrohr 13 aufgeschraubt ist. Um das Magnetführungsrohr 13 ist die nur schematisch angedeutete Wicklung 12 des Elektromagneten aufgebaut. In dem Magnetführungsrohr 13 ist der Magnetanker 15 gleitend gelagert. Das Verschlußstück 17,17' ist mit dem Magnetanker 15 durch ein Gewinde verbunden und durch die Kontermutter 9 festgesetzt. In dem Magnetanker 15 sind eine Nutringmanschette 16, ein Kolben 11 mit einem Bund 11' und eine Rückstellfeder 14 untergebracht. Das Verschlußstück 17, 17' ist mit einem Kanal 8 versehen, der den Kolbenraum 10 mit der Ventilkammer 5 verbindet. Wirkungsweise Wird der Ventileingang A mit einer Druckleitung verbunden, ist im Ventil freier Durchfluß von Anschluß A nach Anschluß B. Da der Querschnitt an den Ventilsitzen 20', 20" gleich dem Querschnitt an den Dichtstellen 4', 4" ist, ist das Verschlußstück 17, 17' in jeder Stellung vollkommen entlastet. Durch die völlige Entlastung braucht die Magnetspule bei Erregung nur den Reibungswiderstand der Dichtmittel 4', 4" und den Strömungswiderstand des Druckmittels überwinden. Bei erregter Magnetspule wird das Ventil umgesteuert, und das Verschlußstück 17, 17' dichtet mit der oberen Dichtfläche 17' am Sitz 20" ab. Dadurch wird der Durchgang vom Ventileingang A zum Ventilausgang B geschlossen und der Durchgang vom Ventileingang A zum Ventilausgang C geöffnet. Das Druckmittel strömt durch den Kanal 8 in den Kolbenraum 10, beaufschlagt den Kolben 16, 11, 11' und spannt die Rückstellfeder 14. Bei unerregtem Magneten wird das Verschlußstück 17, 17' von der Feder 14 wieder in die Ausgangsstellung zurückgedrückt, das im Kolbenraum 10 vorhandene Druckmittel fließt in den Ausgang C, und die Feder 14 entspannt sich wieder.The valve housing 1 has a bore 19, in the center of which the spacer ring 21 is fixed. The valve inserts 20 are also received in the bore 19 and held on both sides by the spacer ring 21. The valve interior is divided into three chambers 5, 6, 7 and one chamber with a valve connection, namely chamber 5 with connection C, chamber 6 with the sealing means 3 and the sealing means 4 ', 4 "attached to the closure piece 17, 17' for pressure relief terminal a and chamber 7 with terminal B, respectively. the valve inserts 20 are held by the lid 2, and 1.8 in the valve housing 1. the cover 18 has a threaded neck 18 'is screwed onto the the magnetic guide tube 13. to the magnetic guide tube 13, the only schematically indicated winding 12 constructed of the electromagnet. In the magnetic guide tube 13, the armature 15 is slidably mounted. the closure member 17,17 'is connected by a thread to the armature 15 and fixed by the lock nut 9. In the armature 15, a Nutringmanschette 16, accommodates a piston 11 with a collar 11 'and a return spring 14. The closure piece 17, 17' is provided with a channel 8 which connects the piston enraum 10 with the valve chamber 5 connects. Mode of operation If the valve inlet A is connected to a pressure line, there is free flow in the valve from port A to port B. Since the cross-section at the valve seats 20 ', 20 "is the same as the cross-section at the sealing points 4', 4" , the closure piece 17 is , 17 'completely relieved in every position. Due to the complete relief, the solenoid only needs to overcome the frictional resistance of the sealing means 4 ', 4 " and the flow resistance of the pressure medium when energized. When the solenoid is energized, the valve is reversed and the closure piece 17, 17' seals with the upper sealing surface 17 'on the seat 20 " from. This closes the passage from valve input A to valve output B and opens the passage from valve input A to valve output C. The pressure medium flows through the channel 8 into the piston chamber 10, acts on the piston 16, 11, 11 'and tensions the return spring 14. When the magnet is de-energized, the locking piece 17, 17' is pushed back by the spring 14 into the starting position, which is in the piston chamber 10 existing pressure medium flows into the outlet C, and the spring 14 relaxes again.

Das vorher beschriebene Ventil kann auch als Durchgangs- oder Dreiwegeventil benutzt werden, jedoch wird dann beim Durchgangsventil der Anschluß B blindgeschlossen, der Anschluß A ist der Ventileingang und der Anschluß C Ventilausgang. Beim Dreiwegeventil muß der Kolbenraum 10 durch die Bohrung B mit der Ventilkammer 6 verbunden werden, und der Anschluß C ist dann Ventileingang.The valve described above can also be used as a two-way or three-way valve, but in the case of a two-way valve, port B is blindly closed, port A is the valve inlet and port C is the valve outlet. When three-way valve of the piston chamber 10 must be connected through the bore B with the valve chamber 6, and the terminal C is then input valve.
