Description
Entlastetes Magnetventil mit automatischer Federspannung Zusatz zur Anmeldung: B 75433 XII/47 g -Auslegeschrift 1256 492 Die Erfindung betrifft ein entlastetes Magnetventil mit einem mit dem Magnetanker verbundenen Verschlußstück und einer Rückstellfeder, die bei der magnetischen Betätigung durch einen Kolben gespannt wird und der Kolben über einen inneren Kanal im Verschlußstück vom Ventileinlaß her mit Druckmittel beaufschlagt wird, nach Patentanmeldung B 75433 XII/47 g (deutscheAuslegeschrift 1256 492).Relieved solenoid valve with automatic spring tension addition to Application: B 75433 XII / 47 g -Auslegeschrift 1256 492 The invention relates to a Relieved solenoid valve with a locking piece connected to the magnet armature and a return spring which, upon magnetic actuation, is actuated by a piston is tensioned and the piston via an inner channel in the closure piece from the valve inlet is applied with pressure medium, according to patent application B 75433 XII / 47 g (German Auslegeschrift 1256 492).
Bei diesem Ventil ist der Kolben im Magnetanker untergebracht. Diese Ausführung genügt in den meisten Fällen. Es hat sich jedoch gezeigt, daß es oft zweckmäßig ist, wenn der Kolben nicht im Magnetanker untergebracht wird, weil der Querschnitt des Magnetankers zu sehr geschwächt wird. In weiteren Fällen ist es erforderlich, daß der Kolben im Durchmesser größer sein muß als der Magnetanker, so daß eine Unterbringung im Magnetanker nicht möglich ist. Es kann auch von großem Vorteil sein, wenn die Feder leicht zugänglich ist, um sie auszutauschen, und man somit das Ventil den jeweiligen Betriebsbedingungen anpassen kann.In this valve, the piston is housed in the magnet armature. These Execution is sufficient in most cases. However, it has been shown often it is useful if the piston is not housed in the armature because of the Cross-section of the armature is weakened too much. In other cases it is required that the piston must be larger in diameter than the magnet armature, so that an accommodation in the armature is not possible. It can also be of great importance It would be an advantage if the spring is easily accessible to replace it, and you thus the valve can adapt to the respective operating conditions.
Es ist Aufgabe der Erfindung, diese Nachteile zu vermeiden.It is the object of the invention to avoid these disadvantages.
Nach der Erfindung wird das dadurch erreicht, daß die Rückstellfeder und der abgedichtete Kolben nicht mehr im Magnetanker, sondern im unteren Teil des Verschlußstückes untergebracht sind.According to the invention this is achieved in that the return spring and the sealed piston is no longer in the armature, but in the lower part of the Closure piece are housed.
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 in der Bohrung aufgenommen und beiderseits vom Distanzring 21 gehalten. Durch die Abdichtmittel3 und die am Verschlußstück 17,17' zur Druckentlastung angebrachten Abdichtmittel 4', 4" wird der Ventilinnenraum in drei Kammern 5, 6, 7 geteilt und jeweils eine Kammer mit einem Ventilanschluß, nämlich Kammer 5 mit Anschluß B, Kammer 6 mit Anschluß A und Kammer 7 mit Anschluß C, verbunden. Die Ventileinsätze 20 werden durch die Deckel 2 und 18, die je einen Gewindeeinsatz haben, im Ventilgehäuse 1 gehalten. Auf den Deckel 18 wird das Magnetführungsrohr 13 und auf den Deckel 2 die Verschraubung 21 aufgeschraubt. Am Boden der Verschraubung 21 stützt sich die Rückstellfeder 14 ab. 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. Im unteren Teil des Verschlußstückes sind eine Nutringmanschette 16, ein Kolben 11 mit einem Bund 11' und die Rückstellfeder 14 untergebracht. Das Verschlußstück 17, 17' ist mit einem Kanal 8 versehen, der den Kolbenraum 10 mit der Ventilkammer 7 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 dem Ventilsitz 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 unteren 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 Feder 14. Bei unerregtem Magneten wird das Verschlußstück 17, 17' von der Feder 14 wieder in die Ausgangsstellung zurückgedrückt, das im Kolbenraum 10 vorhandene Durchflußmittel fließt in den Ausgang C, und die Feder 14 entspannt sich wieder. 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 8 mit der Ventilkammer 6 verbunden werden, und der Anschluß C ist dann Ventileingang.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 and held on both sides by the spacer ring 21. The interior of the valve is divided into three chambers 5, 6, 7 and one chamber with a valve connection, namely chamber 5 with connection B and chamber 6 with the sealing means 3 and the sealing means 4 ', 4 "attached to the closure piece 17, 17' for pressure relief Connection A and chamber 7 are connected to connection C. The valve inserts 20 are held in the valve housing 1 by the covers 2 and 18, each of which has a threaded insert The return spring 14 is supported on the bottom of the screw connection 21. The only schematically indicated winding 12 of the electromagnet is built up around the magnet guide tube 13 connected by a thread and fixed by the lock nut 9. In the lower part of the closure piece, a grooved ring collar 16 and a piston 11 are provided a collar 11 ' and the return spring 14 housed. The closure piece 17, 17 'is provided with a channel 8 which connects the piston chamber 10 with the valve chamber 7. 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 seat 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 lower 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 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 flow medium flows into the outlet C, and the spring 14 relaxes again. 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 8 with the valve chamber 6, and the terminal C is then input valve.
