Abstract

Die Erfindung betrifft ein Schnellöffnungsventil für Auslösevorrichtungen mit unter hohem Druck stehenden Medien. Ziel der Erfindung ist die Steigerung der Kampfkraft durch Erhöhung der Zuverlässigkeit. Aufgabe der Erfindung ist es, ein Schnellöffnungsventil zu schaffen, das einfach in Herstellung und Handhabung ist und eine schnelle Wiederherstellung der Funktionsfähigkeit ermöglicht. Erfindungsgemäß wird dieses dadurch erreicht, daß ein Arbeitskolben aus einem oberen und unteren Schaft besteht, der durch eine Sprengpatrone mit Druck beaufschlagbar ist und durch das Liften durch den unteren Schaft die Verbindung zwischen Druckraum und Überströmkanal freigegeben wird, so daß das Medium fließen kann.The invention relates to a quick opening valve for release devices with high pressure media. The aim of the invention is to increase the combat power by increasing the reliability. The object of the invention is to provide a quick-opening valve that is easy to manufacture and handle and allows quick recovery of functionality. According to the invention this is achieved in that a working piston consists of an upper and lower shaft, which is acted upon by a blasting cartridge with pressure and the connection between the pressure chamber and overflow is released by the lifting through the lower shaft, so that the medium can flow.

Field of application of the invention The invention relates to a quick opening valve for release devices with high pressure media. Characteristic of the known technical solutions In DE-OS 2 343025 a Abscherventil with destructible composite piece is described in which in the release of the piston

mit Scherelement durch Gasdruck betätigt wird, und dabei die Dichtscheibe zerstört, so daß das unter Druck stehende Medium austreten kann.with shear element is actuated by gas pressure, thereby destroying the sealing disc, so that the pressurized medium can escape.

The disadvantage is that due to the small shear surface only low pressures are applicable. It is also a big effort

bei der Herstellung und der Wiederherstellung der Funktionstüchtigkeit erforderlich.required in the manufacture and restoration of the functionality.

Triggering by hand or an emergency release is not possible. In DE OS 3036140 A1 a quick opening valve is set out, in the interior of a bursting cylinder and in this one Explosive cartridge is arranged. When triggered, the bursting cylinder is destroyed and the shaft with the closure is down by the applied pressure

geschoben, so daß das Medium freien Durchtritt hat.pushed, so that the medium has free passage.

The disadvantage is that when closing the valve by the countersunk screw pressure on the bursting cylinder with explosive cartridge

aufgebracht und genau dosiert werden muß, damit einerseits eine zuverlässige Dichtung gewährleistet und andererseits ein vorzeitiger Bersten des Berstzylinders besonders bei dynamischer Belastung ausgeschlossen ist.applied and must be precisely metered, so on the one hand ensures a reliable seal and on the other hand premature rupture of the bursting cylinder is excluded, especially under dynamic load.

The bursting cylinder must thus withstand the applied Dicntkraft and the upcoming pressure of the medium. A hand or. Emergency release is not possible. , · Object of the invention The aim of the invention is to increase the combat power by increasing the reliability. Wasen the invention The object of the invention is to provide an automatically or manually operated opening valve, which is easy in the Manufacture and handling, a rapid restoration of functionality allows a reliable tightness

über Jahre gewährleistet und bei dem der Schaltzustand erkennbar ist.Guaranteed for years and in which the switching state is recognizable.

According to the invention this is achieved in that the working piston has a lower and an upper shaft. The upper, connected to a manual release shaft is guided in an expansion space, which through an overflow

mit einem eine Sprengpatrone enthaltenden, seitlich angeordneten Einschraubstutzen verbunden ist. Der untere Schaft ist in einem abgedichteten Bereich des Gehäuses gelagert, wobei die Abdichtung durch eine Stopfbuchse orfolgt.is connected to a blasting cartridge containing, laterally arranged mounting boss. The lower shaft is mounted in a sealed area of the housing, sealing by a stuffing box.

The manual release consists of a tilting lever, which is guided through a slot in the upper shaft, with lever and Shank have holes for receiving a pin. The open position is indicated by protruding the end of the upper piston skirt out of the housing. By igniting the explosive cartridge, the pressure is passed through the overflow into the expansion space and the Working piston raised. As a result, the lower shaft is simultaneously lifted, so that the medium under high pressure from the pressure chamber in the Overflow can flow. exemplary

Es zeigen Show it

Fig. 1: das Schnellöffnungsventil im Querschnitt, Fig.2: die Seitenansicht.Fig. 1: the quick opening valve in cross section, Figure 2: the side view.

The quick-opening valve consists of a housing 1 with holes for receiving the Arbsitskolbens 10 with the

unteren Schaft 2 und dem oberen Schaft 3.lower shaft 2 and the upper shaft 3.

In the lower part of the housing 1 is the Stopfbuchsonabdichtung with the pressure piece 4, sealing rings 5 and the Spacer 6. The screw 13 for receiving the explosive cartridge is arranged laterally and by a Overflow 11 is connected to the expansion space 12. In the upper part of the valve is the hand opening mechanism with the lever 16. This is stored in the block 17 and

steckt durch einen Schlitz 9 geführt im oberen Schaft 3. Dieser Schlitz 9 ist so lang gestaltet, daß beim Öffnen desinserted through a slot 9 out in the upper shaft 3. This slot 9 is designed so long that when opening the

Quick opening valve of the lever 16 remains in the rest position. The pin 15 is only for closing the valve in the holes

des Schaftes 3 und des Hebels 16 zu stecken. In der geschlossenen Stellung ist der Stift 15 zu entfernen. Zur Sicherung gegen unbefugte Betätigung ist der Hebel 16 in einem geschlitzten Bock 18. Ein Bolzen 19, der verplombt werden kann, verriegelt dieof the shaft 3 and the lever 16 to stick. In the closed position, the pin 15 is removed. To protect against unauthorized operation of the lever 16 in a slotted box 18. A bolt 19, which can be sealed, locks the

Manual operation. The explosive cartridge, which is ignited by a cable 14, generates a gas pressure which flows through the overflow channel 11 in the Expansion space 12 is passed. The pressure acts on the annular surface of the working piston 10 and pushes it upwards. As a result, by the lower shaft 2 of the Path for the flow of the high pressure medium from the pressure chamber 7 in the overflow 8 released. When triggered by hand, the bolt 19 is pulled out when the fuse is sealed and the lever 16 is in position via cable 20
