Description

DEUTSCHESGERMAN

Die Erfindung betrifft eine hydraulisch oder pneumatisch belastete Überdrucksicherung und besteht darin, daß die Schließbelastung auf die große Fläche eines Stufenkolbens wirkt, dessen Ringfläche vom abzusichernden Druck beaufschlagt ist. Dadurch wird erreicht, daß der Gegendruck der Schließbelastung nur einen Bruchteil des abzusichernden Druckes betragen muß und aus zur Verfügung stehenden Druckquellen entnommen werden kann, ohne das besondere Vorkehrungen zum Aufbau eines hohen Druckes ge- ίο troffen werden müssen. Wenn beispielsweise die von dem abzusichernden Leitungsdruck beaufschlagte Ringfläche nur ein Viertel der großen Druckkolbenfläche ausmacht, so genügt auch nur ein Viertel des Leitungsdruckes als Gegendruck.The invention relates to a hydraulically or pneumatically loaded overpressure safety device and consists in that the closing load acts on the large area of a stepped piston, the annular area of which is to be secured Pressure is applied. This ensures that the back pressure of the closing load only has to be a fraction of the pressure to be secured and from available pressure sources can be removed without taking special precautions to build up a high pressure ίο must be met. For example, if the line pressure to be protected is applied Ring area only a quarter of the large pressure piston area matters, only a quarter of the line pressure is sufficient as counter pressure.

Vorzugsweise wird erfindungsgemäß das Verschlußstück als Kolbenschieber ausgebildet, der beim Schließen in die Ablaßleitung eindringt.According to the invention, the closure piece is preferably designed as a piston slide, which at Close penetrates the drain line.

Weiterhin mündet dabei die Druckleitung in einem rechten Winkel zur Kolbenbewegung.Furthermore, the pressure line opens out at a right angle to the piston movement.

Die Erfindung wird in der Zeichnung noch weiter erläutert, welche einen schematischen Schnitt durch eine Ausführungsform der erfindungsgemäßen Überdrucksicherung in der geschlossenen Arbeitsstellung wiedergibt.The invention is further explained in the drawing, which is a schematic section through an embodiment of the overpressure protection according to the invention in the closed working position reproduces.

Die Überdrucksicherung besitzt einen Zylinder 1 mit Kolben 2, dessen oberer Teil 3 und entsprechender unterer Teil 4 in einem Zylinder gleitet. Der Zylinder endet unten in einer Ablaufleitung 5 und ist oben an eine Druckquelle über Leitung 6 mit Druckraum 7 angeschlossen. In der Mitte des Zylinders, das ist der Teil, in welchem der Kolben hin- und her geht, mündet die Druckleitung 8 in einer Erweiterung 9 des Zylinders. Infolgedessen wird nur die Ringfläche 10 des Druckkolbens von dem Leitungsdruck beaufschlagt. Am oberen Ende ist der Druckkolben mit einem Gummipolster 11 ausgerüstet.The overpressure safety device has a cylinder 1 with piston 2, its upper part 3 and the like lower part 4 slides in a cylinder. The cylinder ends at the bottom in a drain line 5 and is at the top a pressure source connected via line 6 to pressure chamber 7. In the middle of the cylinder, that's the one Part in which the piston goes back and forth, the pressure line 8 opens into an extension 9 of the Cylinder. As a result, only the annular surface 10 of the pressure piston is acted upon by the line pressure. The pressure piston is equipped with a rubber pad 11 at the upper end.

Die Wirkungsweise der erfindungsgemäßen Überdrucksicherung ist kurz folgende:The mode of operation of the overpressure safety device according to the invention is briefly as follows:

Entsteht in der Druckleitung 8 ein über den eingestellten Gegendruck hinausgehender Überdruck, so wird der Druckkolben infolge des Überdrucks nach oben geschoben und der Auslaß freigegeben. Die Öffnung des Auslasses erfolgt plötzlich, und der Drucküberdrucksictierimg If an overpressure that exceeds the set counterpressure arises in the pressure line 8, then so the pressure piston is pushed upwards as a result of the overpressure and the outlet is released. The opening the outlet occurs suddenly, and the overpressure sictierimg

kolben bleibt in der geöffneten Stellung stehen, solange ein Überdruck herrscht. Das nachteilige Flattern bekannter Sicherheitsventile (Feder- oder Gewichtsventile) ist ausgeschaltet. Nach Beseitigung des Überdrucks stellt sich die Überdrucksicherung unter Wirkung des Gegendrucks wieder in ihre eingestellte Ausgangslage ein.The piston remains in the open position as long as there is overpressure. The disadvantageous one Fluttering of known safety valves (spring or weight valves) is switched off. After elimination of the overpressure, the overpressure safety device returns to its set position under the action of the counterpressure Starting point.
