Druckluftversorgungssystem für ein PreßluftatemgerätCompressed air supply system for a compressed air breathing apparatus
Die Erfindung betrifft ein Druckluftversorgungssystem für ein Preßluftatemgerät mit einem an eine Preßluftflasche angeschlossenen Druckminderer und an dessen Hoch- und Mitteldruckausgänge angeschlossene Druckleitungen.The invention relates to a compressed air supply system for a compressed air breathing apparatus with a pressure reducer connected to a compressed air bottle and pressure lines connected to its high and medium pressure outlets.
Bei den bekannten Preßluftatemgeräten ist an einer Trageplatte durch einen Spanngurt und durch die Verbindung mit einem Druckminderer eine Preßluftflasche befestigt. Der Druckminderer verfügt über mehrere Ausgänge, von denen Druckluftleitun- gen für Luft mit einem dem Flaschendruck entsprechenden hohen Druck zu einem Manometer bzw. einem entspannten Mitteldruck zu einem mit einer Atemschutzmaske verbundenen Lungenautomaten ausgehen. Von der Hochdruckleitung bzw. der Mitteldruckleitung abzweigende Druckschläuche dienen als Hochdruckschnellfül- lanschluß bzw. als Mitteldruckzweitanschluß. An eine weitere mit dem Druckminderer verbundene Druckleitung ist eine akustische Warneinrichtung angeschlossen. Die einzelnen Druckleitungen sind fest mit dem Druckminderer und den am freien Ende angeschlossenen Geräten verbunden.In the known compressed air breathing apparatus, a compressed air bottle is attached to a support plate by means of a tension belt and by connection to a pressure reducer. The pressure reducer has several outlets from which compressed air lines for air with a high pressure corresponding to the cylinder pressure go to a manometer or a relaxed medium pressure to a regulator connected to a respirator. Pressure hoses branching off from the high-pressure line or the medium-pressure line serve as a high-pressure quick-fill connection or as a second medium-pressure connection. An acoustic warning device is connected to a further pressure line connected to the pressure reducer. The individual pressure lines are firmly connected to the pressure reducer and the devices connected to the free end.
Diese Art der Druckluftversorgung ist insofern nachteilig, als die Vielzahl von Druckleitungen beim Anlegen des Preßluftat- mers und während des Einsatzes der Rettungskräfte hinderlich ist. Es besteht die Gefahr des Hängenbleibens und die Schläu- ehe können durcheinander geraten oder in sich verdreht werden, so daß die Beweglichkeit des Geräteträgers eingeschränkt wird. Bei der Beschädigung einer Hochdruckleitung geht bis zum Schließen des Preßluftflaschenventils viel Luft verloren. Die Handhabung eines Preßluftatemgerätes mit einem solchen Druck- luftversorgungssystem bereitet darüber hinaus insoweit Schwierigkeiten, als die Anschlüsse für Manometer, Lungenautomat, Signalpfeife usw. nicht an ein und derselben Stelle im Frontbereich des Geräteträgers liegen.This type of compressed air supply is disadvantageous in that the large number of pressure lines is a hindrance when the compressed air breathing apparatus is put on and when the rescue workers are deployed. There is a risk of getting caught and the tubing can become confused or twisted, so that the mobility of the device carrier is restricted. If a high pressure line is damaged, a lot of air is lost until the compressed air cylinder valve closes. The handling of a compressed air breathing apparatus with such a compressed air supply system also presents difficulties insofar as the connections for the pressure gauge, regulator, Signal whistle etc. are not in the same place in the front area of the equipment rack.
Der Erfindung liegt daher die Aufgabe zugrunde, das Druckluft- Versorgungssystem eines Preßluftatemgerätes so auszubilden, daß der Benutzungskomfort beim Anlegen und Tragen und Handhaben des Gerätes verbessert wird.The invention is therefore based on the object of designing the compressed air supply system of a compressed air breathing apparatus in such a way that the ease of use when putting on and carrying and handling the apparatus is improved.
Erfindungsgemäß wird die Aufgabe mit einem Druckluftversor- gungssystem gemäß den Merkmalen des Patentanspruches 1 gelöst.According to the invention the object is achieved with a compressed air supply system according to the features of patent claim 1.
Der Grundgedanke der Erfindung liegt in der Anordnung einer einstückigen kombinierten Hoch- und Mitteldruckleitung, die an dem jeweiligen Ende axial drehbar in den Druckminderer und in einen im Frontbereich des Geräteträgers angeordneten Verteilerblock mit mehreren Ausgängen für die unter Hoch- und Mitteldruck zugeführte Luft eingebunden ist. An dem Verteilerblock vorgesehene Hoch- oder Mitteldruckausgänge können mit einem Lungenautomaten, einem Manometer und einer akustischen Warneinrichtung verbunden werden oder als zweiter Mitteldruckanschluß bzw. als Hochdruckschnellfullanschluß benutzt werden.The basic idea of the invention lies in the arrangement of a one-piece combined high and medium pressure line which is integrated at the respective end in an axially rotatable manner in the pressure reducer and in a distributor block arranged in the front region of the equipment carrier and having a plurality of outlets for the air supplied under high and medium pressure. High or medium pressure outlets provided on the distributor block can be connected to a regulator, a pressure gauge and an acoustic warning device or used as a second medium pressure connection or as a high pressure quick fill connection.
Bei einem derartigen Druckluftversorgungs- und -verteilungs- System liegen alle Druckluftausgänge und damit auch die an diese angeschlossenen Meßgeräte, Warngeräte und dgl . an ein und derselben Stelle im Sicht- und Handhabungsbereich des Geräteträgers. Der Handhabung des Gerätes wird somit wesentlich vereinfacht. Zudem ist nur noch eine einzige kombinierte Hoch- und Mitteldruckleitung mit dem Druckminderer verbunden. Dadurch wird die Benutzung des Preßluftatmers weiter erleichtert. Es gibt kein Leitungswirrwarr mehr und selbst die einzige verbleibende Druckluftleitung, die auf einfache Weise entlang eines Rückengurts geführt werden kann, ist nicht in sich verdrehbar, da sie über eine Drehanschlußkupplung axial drehbar im Verteilerblock und im Druckminderer gelagert ist. Da der an den Verteilerblock angeschlossenen akustischen Warneinrichtung sowohl Hochdruckluft als auch Mitteldruckluft zur Verfügung steht, kann diese in vorteilhafter Weise zwar mit Hochdruckluft gesteuert, aber mit Mitteldruckluft betrieben werden, so daß die Erzeugung eines langanhaltenden akustischen Warnsignals mit ausreichender Klangstärke möglich ist.In such a compressed air supply and distribution system, all compressed air outlets and thus also the measuring devices, warning devices and the like connected to them are located. at one and the same place in the viewing and handling area of the equipment carrier. The handling of the device is thus considerably simplified. In addition, only a single combined high and medium pressure line is connected to the pressure reducer. This further facilitates the use of the compressed air breathing apparatus. There is no longer a tangle of lines and even the only remaining compressed air line that can be easily guided along a back belt cannot be twisted as it is axially rotatable in the distributor block and in the pressure reducer via a rotary coupling. There the high-pressure air as well as medium-pressure air is available to the acoustic warning device connected to the distributor block, this can advantageously be controlled with high-pressure air, but can be operated with medium-pressure air, so that the generation of a long-lasting acoustic warning signal with sufficient sound strength is possible.
Gemäß einem weiteren Merkmal der Erfindung ist die kombinierte Hoch- /Mitteldruckleitung als Koaxialleitung ausgebildet, und zwar in der Form, daß im Inneren eines Mitteldruckschlauches aus flexiblem Material eine zum Beispiel schraubenförmig gewundene und ebenfalls flexible Hochdruckleitung angeordnet ist. Bei einem Bruch der Hochdruckleitung gelangt die rasch ausströmende Druckluft nicht unmittelbar ins Freie, sondern in die mit einem Überdruckventil abgesicherte Mitteldruckleitung und kann daher durch den Geräteträger noch veratmet werden.According to a further feature of the invention, the combined high / medium pressure line is designed as a coaxial line, specifically in the form that, for example, a helically wound and also flexible high pressure line is arranged inside a medium pressure hose made of flexible material. If the high-pressure line breaks, the rapidly flowing compressed air does not go directly into the open air, but into the medium-pressure line, which is protected by a pressure relief valve, and can therefore be breathed in by the equipment wearer.
In weiterer Ausbildung der Erfindung umfaßt die Drehanschlußkupplung, über die die kombinierte Hoch-/Mitteldruckleitung an einem Ende in den Verteilerblock und am anderen Ende in denIn a further embodiment of the invention, the rotary connection coupling, via which the combined high / medium pressure line at one end in the distributor block and at the other end in the
Druckminderer axial drehbar eingebunden ist, eine Mitteldruck- Schlauchanschlußtülle und eine gasdicht mit dieser verbundene Hochdruckan-schlußtülle, die drehbar in dem Verteilerblock bzw. dem Verteilergehäuse des Druckminderers gelagert sind und jeweils mit einem Mitteldruckkanal bzw. Hochdruckkanal im Verteilerblock/Verteilergehäuse in Verbindung stehen. In jeder Drehstellung der Hoch- /Mitteldruckleitung bzw. der Drehanschlußkupplung kann entspannte Druckluft in den Mitteldruckschlauch und Hochdruckluft in die Hochdruckleitung ein- strömen bzw. aus diesen in den Verteilerblock ausströmen.Pressure reducer is axially rotatably integrated, a medium-pressure hose connection nozzle and a gas-tightly connected high-pressure connection nozzle, which are rotatably mounted in the distributor block or the distributor housing of the pressure regulator and are each connected to a medium-pressure channel or high-pressure channel in the distributor block / distributor housing. In any rotational position of the high / medium pressure line or the rotary connection coupling, relaxed compressed air can flow into the medium pressure hose and high pressure air into the high pressure line or flow out of the latter into the distributor block.
Der Druck in der Hochdruckleitung liegt zwischen 200 und 300 bar, während der Druck in der Mitteldruckleitung etwa 4 bis 10 bar beträgt . Aus der nachfolgend beschriebenen konkreten Ausführungsform eines Druckversorgungs- und -Verteilungssystems für einen Preßluftatmer sowie den Unteransprüchen ergeben sich weitere Merkmale und vorteilhafte Weiterbildungen der Erfindung.The pressure in the high pressure line is between 200 and 300 bar, while the pressure in the medium pressure line is about 4 to 10 bar. Further features and advantageous developments of the invention result from the specific embodiment of a compressed air supply and distribution system described below for a compressed air breathing apparatus and the subclaims.
Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail with reference to the drawing. Show it:

Bei der in Fig. 1 dargestellten Trageplatte 1 mit zwei Rückengurten 2 und einem Hüftgurt 3 , mit denen die Trageplatte 1 am Geräteträger fixiert wird, sowie mit einem Spanngurt 4 zur Befestigung einer Druckluftflasche (nicht dargestellt) ist am unteren Ende ein Druckminderer 5 befestigt. In dem an die Druckluftflasche angeschlossenen Druckminderer 5 wird ein Teil der unter Hochdruck anliegenden Luft auf einen Mittel- druck entspannt. Von einem Verteilergehäuse 6 des Druckminderers und einer in diesem drehbar angeordneten Kupplung 7 gelangen die Mitteldruckluft bei einem Druck von 10 bar und die Hochdruckluft bei einem Druck von 300 bar über eine einstückige flexible Druckluftverbindungsleitung, das heißt, eine einzige kombinierte 300 bar-Hoch-/10 bar-MitteldruckleitungIn the support plate 1 shown in Fig. 1 with two back straps 2 and a waist belt 3, with which the support plate 1 is fixed to the equipment carrier, and with a tension belt 4 for fastening a compressed air bottle (not shown), a pressure reducer 5 is attached to the lower end. In the pressure reducer 5 connected to the compressed air bottle, part of the air present under high pressure is expanded to a medium pressure. The medium-pressure air at a pressure of 10 bar and the high-pressure air at a pressure of 300 bar pass from a distributor housing 6 of the pressure reducer and a coupling 7 rotatably arranged in it via a one-piece flexible compressed air connection line, that is to say a single combined 300 bar high / 10 bar medium pressure line
8, die an einem der beiden Rückengurte 2 gehalten ist, zu ei- nem im Sicht- und Handhabungsbereich (Frontbereich) des Geräteträgers angeordneten Verteilerblock 9. In dem Verteilerblock 9 werden die zugeführte Hochdruckluft und Mitteldruckluft verteilt, und zwar auf einen ersten Mitteldruckanschluß 10 für eine mit einem Lungenautomaten 11 verbundene Mitteldruckleitung 12, einen zweiten Mitteldruckanschluß 13 und/ oder einen Hochdruckschnellfullanschluß 14, einen Hochdruckanschluß 15' für ein Manometer 15 (oder eine elektronische Messeinheit) und einen Hoch-/Mitteldruckanschluß 16 für eine Warneinrichtung, das heißt, eine durch den Hochdruck gesteuerte und durch den Mitteldruck betriebene Signalpfeife 17.8, which is held on one of the two back straps 2, to Nem arranged in the viewing and handling area (front area) of the equipment carrier distribution block 9. In the distribution block 9, the supplied high pressure air and medium pressure air are distributed, namely to a first medium pressure connection 10 for a medium pressure line 12 connected to a regulator 11, a second medium pressure connection 13 and / or a high-pressure quick-fill connection 14, a high-pressure connection 15 'for a pressure gauge 15 (or an electronic measuring unit) and a high / medium pressure connection 16 for a warning device, that is to say a signal whistle 17 controlled by the high pressure and operated by the medium pressure.
Durch die Anordnung nur einer einzigen Druckluftversorgungs- leitung in Verbindung mit einem an deren Ende im Frontbereich des Geräteträgers befindlichen Verteilerblock 9, in den alle erforderlichen Hoch- und Mitteldruckanschlüsse integriert sind, wird der Benutzungskomfort für den Geräteträger wesentlich verbessert, zumal die kombinierte einstückige Hoch- und Mitteldruckleitung 8 an ihren Enden jeweils drehbar in das Verteilergehäuse 6 des Druckminderers 5 bzw. den Verteilerblock 9 eingebunden ist. Das heißt, die Druckluftversorgungs- leitung kann sich nicht verdrehen. Die Gefahr des Hängenbleibens oder einer anderweitigen Behinderung des Geräteträgers durch eine Vielzahl von Gurten und Verbindungsleitungen wird wesentlich verringert. Die Handhabung und Benutzung des Atemschutzgerätes ist einfach und sicher, da sich das Manometer 15 und die Signalpfeife 17 an einem gemeinsamen Träger (Verteilerblock 9) im unmittelbaren Sicht- und Hörbereich des Geräteträgers befinden.The arrangement of only a single compressed air supply line in connection with a distributor block 9 at the end of which is located in the front area of the equipment carrier and in which all necessary high and medium pressure connections are integrated, the user comfort for the equipment carrier is significantly improved, especially since the combined one-piece high and medium pressure line 8 is rotatably connected at their ends to the distributor housing 6 of the pressure reducer 5 or the distributor block 9. This means that the compressed air supply line cannot twist. The risk of getting caught or otherwise obstructing the equipment carrier through a large number of belts and connecting lines is substantially reduced. The handling and use of the breathing apparatus is simple and safe, since the manometer 15 and the signal whistle 17 are located on a common support (distribution block 9) in the immediate field of vision and hearing of the device wearer.
Wie aus den Figuren 2 und 3 ersichtlich, besteht die kombinierte Hoch-/Mitteldruckleitung 8 aus einem durch einen flexiblen Elastomerschlauch gebildeten 10 bar-Mitteldruck- schlauch 18 und einer koaxial in diesem angeordneten 300 bar- Hochdruckleitung 19 aus hochfestem Material, wie zum Beispiel einer Kupferlegierung oder Teflon. Die Hochdruckleitung 19 ist hier ein schraubenförmig gewundenes Röhrchen mit geringem Durchmesser und daher hochelastisch, so daß die kombinierte Hoch-/Mitteldruckleitung 8 als Ganzes ebenfalls flexibel ist.As can be seen from FIGS. 2 and 3, the combined high / medium pressure line 8 consists of a 10 bar medium pressure hose 18 formed by a flexible elastomer hose and a 300 bar high pressure line 19 coaxially arranged therein made of high-strength material, such as, for example Copper alloy or teflon. The high pressure line 19 here is a helically wound tube with a small diameter and therefore highly elastic, so that the combined high / medium pressure line 8 as a whole is also flexible.
Ein wesentlicher Vorteil ist, daß die hier als Koaxialleitung ausgebildete einzige Hoch-/Mitteldruckleitung axial drehbar in dem Verteilergehäuse 6 und dem Verteilerblock 9 angeordnet werden kann. In dem Verteilergehäuse 6 / Verteilerblock 9 sind zu diesem Zweck jeweils ein erster Lagerzylinder 20 mit einem radial anschließenden Mitteldruckkanal 21 und ein von dem Boden des ersten Lagerzylinders 20 ausgehender zweiter Lagerzylinder 22 mit einem axial in diesen mündenden Hochdruckkanal 23 ausgebildet. In dem ersten Lagerzylinder 20 ist eine Mitteldruck-Schlauchanschlußtülle 24 drehbar gelagert, durch einen Sicherungssplint axial arretiert und jeweils mit einem Dichtungsring 26 nach außen und zum Hochdruckkanal 23 hin abgedichtet. In Höhe des Mitteldruckkanals 21 befinden sich in der Mitteldruck-Schlauchanschlußtülle 24 eine an deren Umfang umlaufende Ringnut 27 sowie eine radiale Durch- gangsbohrung 28. Somit kann über den Mitteldruckkanal 21 zugeführte Druckluft über die Ringnut 27 und die Durchgangsboh- rung 28 in die Mitteldruck-Schlauchanschlußtülle 24 und in den Mitteldruckschlauch 18 der Hoch- /Mitteldruckleitung 8 gelangen.A significant advantage is that the single high / medium pressure line, which is designed here as a coaxial line, can be arranged in the distributor housing 6 and the distributor block 9 so that it can rotate axially. For this purpose, a first bearing cylinder 20 with a radially adjoining medium pressure channel 21 and a second bearing cylinder 22 starting from the bottom of the first bearing cylinder 20 with an axially opening high pressure channel 23 are formed in the distributor housing 6 / distributor block 9. In the first bearing cylinder 20, a medium-pressure hose connection nozzle 24 is rotatably mounted, axially locked by a split pin and each sealed with a sealing ring 26 to the outside and to the high-pressure duct 23. At the level of the medium-pressure channel 21 there is an annular groove 27 encircling its circumference in the medium-pressure hose connection nozzle 24, as well as a radial through-hole 28. Compressed air supplied via the medium-pressure channel 21 can thus be fed into the medium-pressure Hose connection nozzle 24 and get into the medium pressure hose 18 of the high / medium pressure line 8.
Der Mitteldruckschlauch 18 (Elastomerschlauch) ist mittels einer Preßhülse 29 auf dem aus dem Verteilergehäuse 6 bzw. Verteilerblock 9 herausragenden Teil der Mitteldruck- Schlauchanschlußtülle 24 befestigt. Der Hochdruckanschluß an die innerhalb des Mitteldruckschlauches 18 angeordnete schraubenförmige Hochdruckleitung 19 erfolgt über eine in dem zweiten Lagerzylinder 22 und der Mitteldruck- Schlauchanschlußtülle 24 jeweils über einen Dichtungsring 30,31 abgedichtete, drehbar gelagerte Hochdruckanschlußtülle 32. Damit steht für den Transport der Hochdruckluft und derThe medium-pressure hose 18 (elastomer hose) is fastened by means of a compression sleeve 29 to the part of the medium-pressure hose connector 24 protruding from the distributor housing 6 or distributor block 9. The high-pressure connection to the helical high-pressure line 19 arranged within the medium-pressure hose 18 takes place via a rotatably mounted high-pressure connection nozzle 32, which is sealed in the second bearing cylinder 22 and the medium-pressure hose connection nozzle 24, in each case by means of a sealing ring 30, 31
Mitteldruckluft zwischen dem Verteilergehäuse 6 des Druckmin- derers 5 und dem Verteilerblock 9 an der Frontseite des Geräteträgers eine flexible und axial drehbewegliche Druckluftverbindungsleitung (kombinierte Hoch-/Mitteldruckleitung 8) zur Verfügung, die sich auch nicht verwinden kann und dadurch den Benutzungskomfort des Preßluftatemgerätes weiter verbessert. Ein weiterer Vorteil der kombinierten Hoch-/Mittel- druckleitung 8 besteht schließlich darin, daß die innen liegende Hochdruckleitung 19 durch den diese umhüllenden Mitteldruckschlauch 18 geschützt ist. Bei einem Bruch der Hoch- druckleitung 19 strömt die austretende Luft nicht sofort ins Freie, sondern in den mit dem Lungenautomaten 11 verbundenen Mitteldruckschlauch 18. Die Luft kann dadurch noch durch den Geräteträger veratmet werden und strömt erst bei größeren Leckagen, abgesichert durch ein Überdruckventil, ins Freie.Medium pressure air between the distributor housing 6 of the pressure min. derers 5 and the distributor block 9 on the front of the equipment carrier a flexible and axially rotatable compressed air connection line (combined high / medium pressure line 8) available, which can not twist and thereby further improves the ease of use of the compressed air breathing apparatus. Another advantage of the combined high / medium pressure line 8 is finally that the internal high pressure line 19 is protected by the medium pressure hose 18 enveloping it. If the high-pressure line 19 breaks, the escaping air does not immediately flow into the open air, but into the medium-pressure hose 18 connected to the regulator 11. As a result, the air can still be breathed through the device carrier and only flows in the event of major leaks, secured by a pressure relief valve. into the open.
Eine Ausführungsvariante für die axial drehbare Einbindung der kombinierten koaxialen Hoch-/Mitteldruckleitung 8 in das Verteilergehäuse 6 bzw. den Verteilerblock 9 ist in Fig. 3 wiedergegeben. In diesem Fall weist die Mitteldruck- Schlauchanschlußtülle 24' im gesamten oberen Abschnitt im Bereich des Mitteldruckkanals 21 einen verringerten Durchmesser auf und die Hochdruckanschlußtülle 32 ' ist fest in die Mitteldruck-Schlauchanschlußtülle 24' eingebunden, so daß im Bereich des ersten und zweiten LagerZylinders 20 und 22 jeweils nur ein Dichtring 28' und 30' benötigt wird. An embodiment variant for the axially rotatable integration of the combined coaxial high / medium pressure line 8 into the distributor housing 6 or the distributor block 9 is shown in FIG. 3. In this case, the medium-pressure hose connection nozzle 24 'has a reduced diameter in the entire upper section in the region of the medium-pressure channel 21 and the high-pressure connection nozzle 32' is firmly integrated into the medium-pressure hose connection nozzle 24 ', so that in the region of the first and second bearing cylinders 20 and 22 only one sealing ring 28 'and 30' is required.
