Description
Es ist bekannt. mittels eines Hilfsventils ein Hauptventil in der Weise zu steuern, daß an einem mit dem Hauptventil. verbundenen Steuerkolben, der im Ruhezustand auf beiden Seiten vom Druck des zu steuernden Mediums (Fluds - ) beeinflußt wird. mittels des Hilfs- ventils der Druck auf der einen Kolbenseite abgelassen wird, so daß der Druck auf der anderen Seite überwiegt und den Kolben sanit Hauptventil in die Öffnungslage bewegt, während bei geschlossenem Hilfsventil wieder ein Druckausgleich beiderseits des Steuerkolbens durch einen engen Kanal oder eine Undichtheit eintritt. der das Hauptventil in seine Schließlage zurückkehren läßt. It is known. by means of an auxiliary valve to control a main valve in such a way that at one with the main valve. connected control piston, which is influenced on both sides by the pressure of the medium to be controlled (Fluds -) at rest. By means of the auxiliary valve, the pressure on one side of the piston is released so that the pressure on the other side predominates and the piston moves into the open position, while when the auxiliary valve is closed, there is again pressure equalization on both sides of the control piston through a narrow channel or a leak entry. which allows the main valve to return to its closed position.
Bei verhältnismäßig großem Hauptventil und entsprechend großem Steuerkolben besteht nun die -Möglichkeit daß die Undichtheit etwa ebensoviel oder gar noch mehr Flud durchläßt als das geöffnete Hilfsventil und dann die gewünschte Steuerung nicht zustande kommt.With a relatively large main valve and a correspondingly large control piston there is now the possibility that the leakage is about as much or even more Flud does not let through as the opened auxiliary valve and then the desired control comes about.
Uin dem abzuhelfen -. ist gemäß der Erfindung dem mit dem Hauptveritil verbundenen Kolben ein Hilfskolben vorgelagert worden, der vorn Hilfsventil gesteuert wird und nun seinerseits den Hauptkolben steuert. Dadurch ist zugleich die praktische 'Möglichkeit geschaffen, dasselbe kleine Hilfsventil unverändert auch für beliebig große Hauptventile und Steuerkolben zu verwenden.U to remedy that -. According to the invention, the piston connected to the main valve is preceded by an auxiliary piston which is controlled by the auxiliary valve and now in turn controls the main piston. This also creates the practical 'possibility of using the same small auxiliary valve unchanged for any size main valve and control piston.
Ein Ausführungsbeispiel ist in der Zeichnuner in einem Axialschnitt dargestellt.One embodiment is shown in the drawing in an axial section shown.
Das Hauptventil a ist mit einem Steuerkolben b verbunden. der mit einer gewissen Undichtheit c in seinem Zvlinder d beweglich ist und von einer 'Mittelb#hrung e durchsetzt ist. Diese Mittelbolirung ist für gewöhnlich verschlossen durch die Dichtscheibe f eines Hilfskolbens -, der ebenso wie der Hauptkolben von einer 'Mittelbohrungh durchsetzt ist und in seinem Zvlinder i nicht vollständig dicht geführt ist.The main valve a is connected to a control piston b . which is movable in its cylinder d with a certain leakage c and is penetrated by a central guide e. This central bore is usually closed by the sealing washer f of an auxiliary piston - which, like the main piston, is penetrated by a central bore and is not completely sealed in its cylinder i.
Die 'Mittelbohrung li ist nun vom Schließkörper k des Hilfsventils beherrscht. das in an sich bekannter Weise mittels des Kerns in 1 eines Elektromagneten ji gesteuert werden kann.The 'central bore li is now dominated by the closing body k of the auxiliary valve. which can be controlled in a manner known per se by means of the core in FIG. 1 of an electromagnet ji.
In dem gezeichneten Ruhezustand wirkt der Druck des bei o in das Ventilgehäuse eintretenden Fluds auf die Ringfläche p des mit dem Hauptventil a verbundenen Kolbens b. Derselbe Druck herrscht aber auch im Raum q hinter dem Kolben b infolge des Druckaus-"leiches durch die Undichtheit c hindurch, so daß das Hatiptventil a auf seinem Sitz ruhen bleibt und den Durchtritt des Fluds absperrt. Die Mittelbohrting c ist durch die Dichtscheibe f des Hilf skolhens - abgeschlossen und ebenso die 'MittelbohrunIgh des Hilfskolbens durch den Abschlußkörper 1, des Hilfsventils. Auch beiderseits des Hilfskolbens - herrscht der Druck des dem Ventil zugeführten Fluds.In the idle state shown, the pressure of the fluid entering the valve housing at o acts on the annular surface p of the piston b connected to the main valve a. However, the same pressure prevails in the space q behind the piston b due to the breather capillary "leiches by the leakage c therethrough, so that the Hatiptventil a remains resting on its seat and shuts off the passage of the Fluds. The Mittelbohrting c f by the sealing disc of the Helpful skolhens - completed and also the 'MittelbohrunIgh of the auxiliary piston through the sealing body 1, the auxiliary valve is also on both sides of the auxiliary piston -. prevails the pressure of the valve supplied Fluds.
Wird nun das Hilfsventil k- mittels Elektroniao'neten a und -Kern m geöffnet, dann wird der oberhalb des Hilfskolbeiis herrschende Druck durch die Mittelbohrungen li und c nach der Auslaßseite des Ventils abgelassen. Der Druck auf der unteren Seite des Hilfskolben-, - überwie-t und bewirkt ein Abheben der Dichtscheibe t von der Mittelbohrung c des Hauptsteuerkolbens 1). N-un wird auch der Druck- im Rauni (1 trotz des Bestehen, der Undichtheit c rasch zum Verschwinden gebracht. da die 'Mittelbohrung c eineii vergleichsweise großen Querschnitt 1 iaben kann. Es überwiegt jetzt der Druck auf der unteren Kolbenringfläche p und veranlaßt ein Anheben des Kolbens lk und des #-entils c7, also ein Minen des Durchflusses. If the auxiliary valve k is now opened by means of electronics a and core m , then the pressure prevailing above the auxiliary piston is released through the central bores li and c to the outlet side of the valve. The pressure on the lower side of the auxiliary piston - predominates and causes the sealing disk t to lift off the central bore c of the main control piston 1). N-un c is rapidly brought and the pressure in the Rauni (1, despite the existence of the leak to disappear. As the 'central bore c can iaben eineii comparatively large cross-section 1. It now prevails the pressure on the lower piston ring surface p and causes a Lifting the piston lk and the # -valve c7, so a mining of the flow.
Läßt man das Hilfsventil 7, wieder auf seinen Sitz zurücksinken. so gleicht sich zunächst der Druck beiderseits des Hilfskolbens g aus. und der Kolben schließt dann die Mittelbohrung e des Hauptkolbens b ab. worauf auch ein Druckausgleich beiderseits dieses Kolbens stattfindet und infolgedessen ein Schließen des Hauptventils.If the auxiliary valve 7 is allowed to sink back onto its seat. so initially the pressure on both sides of the auxiliary piston g is equalized. and the piston then closes the central bore e of the main piston b . whereupon pressure equalization takes place on both sides of this piston and as a result the main valve closes.
An Stelle der gezeichneten elektrornagnetischen Steuerung des Hilf sventils könnte auch irgendeine andere Steuerung, z. B. mittels 'Jembran, treten.Instead of the drawn electromagnetic control of the auxiliary sventils could also be any other control, e.g. B. by means of 'Jembran, step.
