Description
Druckregelv orrichtungen werden benutzt an Maschinen, welche mit Druckflüssigkeit, Druckluft oder Dampf betrieben werden, oder bei Anlagen, welche unter Flüssigkeits- oder Gasdruck stehen. und dienen dazu, den Druck an der Verbrauchsstelle in geringen Grenzen gleichbleibend zu halten. Sie bestehen aus Absperrorganen. welche die Zuflußleitung zu der Verbrauchsstelle absperren, wenn der gewünschteDruck erreicht ist, und wieder öffnen. wenn ein Druckabfall eintritt. Die Betätigung dieser Absperrorgane erfolgt meistens selbsttätig durch geeignete, druckabhängige Übertragungen, wie Kontaktmanometer, mit Federn oder Gewichten belastete Kolben u. dgl.Pressure regulating devices are used on machines that operate with hydraulic fluid, Compressed air or steam are operated, or in systems that operate under liquid or gas pressure. and serve to reduce the pressure at the point of consumption in low To keep boundaries constant. They consist of shut-off devices. which the inflow line to the point of consumption when the desired pressure is reached and again to open. when a pressure drop occurs. The actuation of these shut-off devices takes place mostly automatically through suitable, pressure-dependent transmissions, such as contact pressure gauges, Pistons loaded with springs or weights, etc.
Wenn diese Druckregelorgane undicht sind, so kann es vorkommen, daß der Druck an der Verbrauchsstelle über das gewünschte oder zulässige 'Maß ansteigt und Überanstrengungen oder Zerstörungen veranlaßt. Die Erfindung bezweckt, einen solchen unzulässigen Druckanstieg zu verhindern, und wird dadurch gekennzeichnet, daß zwischen dem Druckregelorgan und einem in die Leitung eingeschalteten Rückschlagventil ein Zwischenventil eingeschaltet ist, welches bei geschlossenem Absperrventil geöffnet wird, um die durch U ndichtheit des Absperrventils übertretende Druckflüssigkeit ins Freie abzuleiten.If these pressure regulating elements are leaking, it can happen that the pressure at the point of consumption rises above the desired or permissible level and causes overexertion or destruction. The invention aims to provide a to prevent such an unacceptable rise in pressure, and is characterized by that between the pressure regulator and a check valve connected in the line an intermediate valve is switched on, which opens when the shut-off valve is closed is to reduce the pressure fluid overflowing due to the leakage of the shut-off valve to divert into the open.
Die Abbildung zeigt ein Ausführungsbeispiel. In die von dem Druckspeicher zur Verbrauchsstelle von a nach b gehende Leitung sind ein Absperrventil c und ein Rücksehlagventil d 'eingeschaltet. Das Absperrventil c wird, solange in der Verbrauchsstelle b Druckflüssigkeit benötigt wird, durch einen Elektromagneten ofiengehalten. Der Magnet g wird durch einen Selbstschalter 1c und ein Kontaktmanometer i gesteuert. Das Kontaktmanometer -ist an die zur Verbrauchsstelle führende Leitung b oder unmittelbar an der -\'erbrauchsstelle angeschlossen. Nenn der Druck P an der Verbrauchsstelle die gewünschte und am Kontaktmanometer eingestellte Höhe erreicht hat, wird der Maximalkontakt des letzteren geschlossen, der Magnet g wird stromlos und fällt ab. Das Regelventil c schließt sich und verhindert einen weiteren Druckanstieg an der Verbrauchsstelle.The figure shows an exemplary embodiment. A shut-off valve c and a non-return valve d 'are switched on in the line going from the pressure accumulator to the point of consumption from a to b. The shut-off valve c is kept open by an electromagnet as long as pressure fluid is required in the point of consumption b. The magnet g is controlled by an automatic switch 1c and a contact manometer i. The contact pressure gauge is connected to the line b leading to the point of use or directly to the point of use. If the pressure P at the point of consumption has reached the desired level set on the contact manometer, the maximum contact of the latter is closed, the magnet g is de-energized and drops out. The control valve c closes and prevents a further increase in pressure at the point of consumption.
Zwischen dem Absperrventil c und Rückschlagventil d ist ein Zwischenventil e eingeschaltet, welches mit dem Absperrventil c durch den Hebel f so verbunden ist, daß es schließt, solange das Absperrventil c offen ist. Sollten nun bei geschlossenem Ventil c Undichtheiten an diesem vorhanden sein, so kann die hindurchtretende Druckflüssigkeit durch das geöffnete Ventil e ins Freie treten, ohne weiteren Druckanstieg an der -#'erl>rauchsstelle b zu veranlassen. Der Druck an der Verbrauchsstelle bleibt aufrechterhalten, da das Rückschlagventil d geschlossen ist.C between the shutoff valve and check valve d is switched between a valve e, which c with the check valve by the lever f is connected so that it closes as long as the shut-off valve is open c. If there are leaks on valve c when it is closed, the hydraulic fluid that passes through can enter the open air through the open valve e without causing any further pressure increase at the smoke point b. The pressure at the point of consumption is maintained because the check valve d is closed.
Wenn durch irgendwelche Umstände der Druck an der Verbrauchsstelle b fällt, so wird der Minimalkontakt des Kontaktmanometers i geschlossen, der Magnet g erhält wieder Strom und schließt das Ventil e und öffnet das Ventil c, so daß neue Druckflüssigkeit zur Verbrauchsstelle eintreten und den ursprünglichen Druck wiederherstellen kann.If by any circumstances the pressure at the point of consumption b falls, the minimum contact of the contact manometer i is closed, the magnet g receives power again and closes valve e and opens valve c, so that new hydraulic fluid enter the point of consumption and the original pressure can restore.
An Stelle des Magneten g können zur Betätigung der Ventile c und e auch druckabhängige Vorrichtungen, wie Kolben, die durch Feder und Gewichte belastet sind, treten.Instead of the magnet g can be used to actuate the valves c and e also pressure-dependent devices, such as pistons, which are loaded by springs and weights are, kick.
