An outlet valve in gas-pressurized submarine torpedo launchers for launching weapons by means of compressed gas which is suppliable from associated compressed-gas containers and controllable via a circuit arrangement, the speed of the opening stroke of the shut-off member (3) being predetermined as per system conditions, characterized in that the shut-off member (3) projects as a plug-like valve body (19) into a discharge bore (2) and the plug-like valve body (19) and/or the discharge bore (2) has a plurality of step-like shoulders such that the opening cross section increases discontinuously depending on the stroke.

Description

Die Erfindung bezieht sich auf ein Auslaßventil in Ausblaseinrichtungen für Ausstoß- und Ablaufrohre von U-Booten zum Ausstoßen von Waffen mittels Druckgas, das aus zugeordneten Druckgasbehältern zuführbar und über eine Schaltungsanordnung steuerbar ist, wobei die Geschwindigkeit des Öffnungshubes des Absperrorgans systembedingt vorgegeben ist.The invention relates to an outlet valve in blow-out devices for ejection and drain pipes of submarines for ejecting weapons by means of compressed gas, which can be supplied from associated compressed gas containers and controlled via a circuit arrangement, the speed of the opening stroke of the shut-off element being predetermined by the system.

Bei Ventilen dieser Art besteht das Problem, neben den eigentlichen Öffnungsfunktionen auch eine Steuerfunktion zu erfüllen, um die auszustoßenden Waffen bei allen Tauchtiefen mit vorgegebenen Geschwindigkeiten auszustoßen. Hierbei ist es somit erforderlich, die Durchsatzmengen und damit den Auslaßquerschnitt in Anpassung an die Tauchtiefe stark zu verändern. Es ist hierzu beispielsweise bekannt geworden, durch eine hydraulische Dämpfungseinrichtung die Öffnungsgeschwindigkeit des Auslaßventils in einem einstellbaren Geschwindigkeitsbereich konstant zu halten, wobei dieser Geschwindigkeitsbereich an die jeweilige Tauchtiefe angepaßt werden muß.With valves of this type, there is the problem of performing a control function in addition to the actual opening functions in order to eject the weapons to be ejected at all diving depths at predetermined speeds. It is therefore necessary to greatly change the throughput quantities and thus the outlet cross section to match the depth of the dive. For this purpose, it has become known, for example, to keep the opening speed of the outlet valve constant in an adjustable speed range by means of a hydraulic damping device, this speed range having to be adapted to the respective diving depth.

Die Aufgabe der Erfindung ist es, ein Auslaßventil der gattungsgemäßen Art zu schaffen, das einen einfachen mechanischen Aufbau ermöglicht und eine Anpassung der Öffnungsgeschwindigkeit an unterschiedliche Tauchtiefen durch zusätzliche Einstellungen im wesentlichen nicht mehr erforderlich macht.The object of the invention is to provide an outlet valve of the generic type which enables a simple mechanical structure and essentially no longer requires an adaptation of the opening speed to different diving depths by additional settings.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß das Absperrorgan als zapfenartiger Ventilkörper in eine Austrittsbohrung hineinragt und der zapfenartige Ventilkörper und /oder die Austrittsbohrung mehrere stufenartige Absätze derart aufweist, daß sich ein Öffnungsquerschnitt hubabhängig diskontinuierlich erweitert.This object is achieved according to the invention in that the shut-off element projects as a peg-like valve body into an outlet bore and the peg-like valve body and / or the outlet bore has a plurality of step-like shoulders such that that an opening cross-section widened discontinuously depending on the stroke.

Hierdurch wird bei konstanter Hübgeschwindigkeit des Auslaßventils der Durchtrittsquerschnitt für das Preßgas in mehreren diskontinuierlichen Sprüngen erweitert.As a result, the passage cross section for the pressurized gas is expanded in several discontinuous jumps at a constant speed of the exhaust valve.

Weiterhin wird zur Erzielung eines abschnittweisen konstanten Öffnungsquerschnittes vorgeschlagen, daß die gebildeten Absätze über einen Hubabschnitt annähernd konstant ausgebildet sind.Furthermore, in order to achieve a section-wise constant opening cross-section, it is proposed that the shoulders formed be designed to be approximately constant over a lifting section.

Zur weiteren Beeinflussung des Durchtrittsquerschnittes ist vorgesehen, daß zwischen den einzelnen Absätzen Übergangsbereiche mit im wesentlichen linearen oder quadratischen Querschnittserweiterungen ausgebildet sind. Zusätzlich wird vorgeschlagen, daß der Endbereich des zapfenartigen Ventilkörpers als kegelförmiger Ansatz ausgebildet ist.To further influence the passage cross-section, it is provided that transition areas with essentially linear or square cross-sectional widenings are formed between the individual paragraphs. In addition, it is proposed that the end region of the pin-like valve body is designed as a conical extension.

Es hat sich gezeigt, daß eine besonders vorteilhafte Ausgestaltung der Absätze dadurch geschaffen wird, daß der in Hubrichtung wirksame erste Absatz einen Öffnungsquerschnitt kleiner als 7 % und die nachfolgenden Absätze jeweils einen Öffnungsquerschnitt größer als 7 % des Maximalquerschnittes freigeben.It has been shown that a particularly advantageous embodiment of the paragraphs is created in that the first paragraph effective in the stroke direction releases an opening cross-section smaller than 7% and the subsequent paragraphs each an opening cross-section larger than 7% of the maximum cross-section.

In der Zeichnung sind Ausführungsbeispiele der erfindungsgemäßen Ausbildung schematisch dargestellt. Es zeigen:

  • Figur 1 einen Schnitt durch ein Absperrorgan mit einem sich stufenförmig verjüngenden Ventilkörper in einer zylindrischen Austrittsbohrung und
  • Figur 2 einen Schnitt durch ein Absperrorgan mit einem zylindrischen Ventilkörper und einer sich stufenförmig verjüngenden Austrittsbohrung.
Exemplary embodiments of the design according to the invention are shown schematically in the drawing. Show it:
  • Figure 1 shows a section through a shut-off device with a step-like tapered valve body in a cylindrical outlet bore and
  • Figure 2 shows a section through a shut-off device with a cylindrical valve body and a tapered outlet bore.

Ein dargestelltes Ventilgehäuse 1 ist mit einer Austrittsbohrung 2 versehen und besitzt ein Absperrorgan 3 mit einer stirnseitigen Dichtung 4, welche im geschlossenen Zustand an einem Ventilsitz 5 anliegt und damit einen Gasdurchtritt aus einem Druckraum 6 in die Austrittsbohrung 2 verhindert. Das Absperrorgan 3 weist einen zapfenartigen Ventilkörper 19 auf, der im Ruhezustand in die Austrittsbohrung 2 hineinragt. Über einen Ventilschaft 7 wird das Auslaßventil bei Einleitung eines Ausblasvorganges mit einer nicht näher dargestellten systembedingten Öffnungsgeschwindigkeit, die im Normalfall in etwa konstant ist, geöffnet. Dabei wird der Durchtritt an der axialen Dichtung 4 freigegeben und der Öffnungsquerschnitt gemäß Fig. 1 während eines ersten Teils 8 des Hubs durch den Durchmesser der Austrittsbohrung 2 und den Durchmesser 9 des Ventilkörpers 19 bestimmt. Nach Durchlaufen eines Übergangsbereiches 10 mit quadratisch mit dem Hub zunehmenden Querschnitt, d.h. kegelförmiger Kontur, wird ein zweiter konstanter Querschnitt über den Teil 11 des Hubes wirksam. Die Größe des Querschnittes wird bestimmt durch sich gegenüberstehende Durchmesser 2 und 12. Daran schließt sich ein weiterer Übergangsbereich 13 und ein dritter Querschnitt im Bereich des Teilhubes 14 an, dessen Größe durch die Durchmesser 2 und 15 festgelegt ist. Nach Überschreiten des Teilhubes 14 wird der kegelförmige Ansatz 16 wirksam, womit der maximal mögliche Öffnungsquerschnitt des Ventils erreicht wird. Der Durchmesser 2 der Austrittsbohrung erstreckt sich fortlaufend über die gesamte Länge 17 des Ventilkörpers 19, die beabsichtigte Ventilwirkung wird jedoch auch dann erreicht, wenn der Durchmesser 2 nur über einen kurzen Bereich 18 in der Nähe des Ventilsitzes 5 vorhanden ist.A valve housing 1 shown is provided with an outlet bore 2 and has a shut-off device 3 with an end seal 4 which, in the closed state, bears against a valve seat 5 and thus prevents gas passage from a pressure chamber 6 into the outlet bore 2. The shut-off device 3 has a peg-like valve body 19 which projects into the outlet bore 2 in the idle state. Via a valve stem 7, the outlet valve is opened at the start of a blow-out process with a system-dependent opening speed, not shown, which is normally approximately constant. The passage on the axial seal 4 is released and the opening cross section according to FIG. 1 is determined during a first part 8 of the stroke by the diameter of the outlet bore 2 and the diameter 9 of the valve body 19. After passing through a transition region 10 with a cross section increasing in square with the stroke, i.e. conical contour, a second constant cross-section is effective over part 11 of the stroke. The size of the cross section is determined by opposing diameters 2 and 12. This is followed by a further transition area 13 and a third cross section in the area of the partial stroke 14, the size of which is determined by the diameters 2 and 15. After the partial stroke 14 has been exceeded, the conical extension 16 takes effect, with which the maximum possible opening cross section of the valve is achieved. The diameter 2 of the outlet bore extends continuously over the entire length 17 of the valve body 19, but the intended valve action is also achieved if the diameter 2 is only present over a short area 18 in the vicinity of the valve seat 5.

Gemäß Fig. 2 ist eine Ausführungsform mit dem Ventilgehäuse 1, dem Absperrorgan 3 mit einem zylindrischen zapfenartigen Ventilkörper 19 und einem Kegelstumpf 16 als Abschluß dargestellt. In diesem Fall wird der gesamte gesteuerte Ventilhub durch die Länge 20 des Ventilkörpers 19 bestimmt. Die Teillängen, in denen die einzelnen im wesentlichen konstanten Querschnitte wirksam werden, sind bestimmt durch die Längen 21,22,23. Die zugehörigen Querschnitte ergeben sich aus dem Zapfendurchmesser 24 einerseits und den Stufendurchmessern 25, 26,27 andererseits der Austrittsbohrung. Die Übergänge zwischen den einzelnen Querschnitten sind hier linear angenommen, was bezüglich der Durchmesser eine parabolische Änderung bedeutet. Dieses kann natürlich auch näherungsweise durch kreisbogenförmige Übergänge ersetzt werden.2 is an embodiment with the valve housing 1, the shut-off device 3 with a cylindrical pin-like valve body 19 and a truncated cone 16 presented as a conclusion. In this case, the total controlled valve lift is determined by the length 20 of the valve body 19. The partial lengths in which the individual essentially constant cross sections are effective are determined by the lengths 21, 22, 23. The associated cross sections result from the pin diameter 24 on the one hand and the step diameters 25, 26, 27 on the other hand from the outlet bore. The transitions between the individual cross sections are assumed to be linear here, which means a parabolic change with regard to the diameter. Of course, this can also be replaced approximately by circular transitions.
