Description

Die vorliegende Erfindung betrifft eine Druckluftbehältereinheit mit Druckbehälter und Wegeventil zur Verwendung in pneumatischen Anlagen gemäß dem Oberbegriff des Anspruchs 1. Druckbehälter in pneumatischen Anlagen speichern komprimierte Luft und dienen zur Versorgung von Druckluftverbrauchern und/oder Druckluftkreisläufen mit Druckluft. Um gesetzliche Bestimmungen zu erfüllen und/oder um die Druckluftverbraucher und/oder Druckluftkreisläufe vom Druckbehälter zu trennen werden sperrende Wegeventile verwendet. Das sperrende Wegeventil wird üblicherweise in der Auslassleitung des Druckbehälters oder auch unmittelbar an der Auslassöffnung des Druckbehälters montiert. Druckbehälter und sperrende Wegeventile sind bekannt ( EP 2 591 257 B1 ). Die Komponenten Druckspeicher, Wegeventil und Montagezubehör müssen üblicherweise jedoch einzeln disponiert und montiert werden. Außerdem führt selbst eine unmittelbare Montage des Wegeventils an der Auslassöffnung des Druckbehälters zu einer insgesamt ungünstigen Einbaulänge und wegen der Vielzahl der außen liegenden Bauteile ist eine äußere Reinigung aufwändig.The present invention relates to a compressed air tank unit with pressure vessel and directional control valve for use in pneumatic systems according to the preamble of claim 1. Pressure tanks in pneumatic systems store compressed air and serve to supply compressed air consumers and / or compressed air circuits with compressed air. In order to meet legal requirements and / or to separate the compressed air consumers and / or compressed air circuits from the pressure vessel locking directional control valves are used. The blocking directional control valve is usually mounted in the outlet line of the pressure vessel or directly at the outlet opening of the pressure vessel. Pressure vessels and blocking valves are known ( EP 2 591 257 B1 ). The components pressure accumulator, directional control valve and mounting accessories must, however, usually be disassembled and mounted individually. In addition, even an immediate installation of the directional control valve at the outlet opening of the pressure vessel leads to an overall unfavorable installation length and because of the large number of external components an external cleaning is complex.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Druckluftbehältereinheit mit Druckbehälter und Wegeventil zu schaffen, die einbaufertig montiert ist, eine geringe Baulänge aufweist und einfach zu Reinigen ist.The protection specified in claim 1 invention is based on the problem of creating a compressed air tank unit with pressure vessel and directional control valve, which is mounted ready to install, has a small length and is easy to clean.

Die genannten Probleme werden mit den im Schutzanspruch 1 aufgeführten Merkmalen gelöst.The above problems are solved with the features listed in the protection claim 1.

Mit der Erfindung wird erreicht, dass die Druckluftbehältereinheit mit Druckbehälter und Wegeventil als einbaufertige Baugruppe disponiert werden kann. Durch das überwiegend in den Druckbehälter eingebaute pneumatisch vorgesteuerte Wegeventil und den Entfall diversen Montagezubehörs ergibt sich vorteilhaft eine insgesamt geringe Baulänge und eine vereinfachte äußere Reinigung.With the invention it is achieved that the compressed air tank unit can be arranged with pressure vessel and directional control valve as a ready-to-install assembly. Due to the pneumatically piloted directional control valve, which is predominantly installed in the pressure vessel, and the omission of various mounting accessories, the overall length is very small and the external cleaning is simplified.

Vorteilhafte Weiterbildungen des Gegenstandes des Anspruchs 1 ergeben sich aus den Merkmalen der Unteransprüche sowie aus der Beschreibung.Advantageous developments of the subject matter of claim 1 will become apparent from the features of the dependent claims and from the description.

Besondere Vorteile der erfindungsgemäßen Druckluftbehältereinheit ergeben sich bei Verwendung in unmittelbarer Nähe von großen Druckluftverbrauchern, z. B. für Blas- und Reinigungsfunktionen, wo eine platzsparende Bauweise von Vorteil ist.Particular advantages of the compressed air tank unit according to the invention arise when used in the immediate vicinity of large compressed air consumers, z. B. for blowing and cleaning functions, where a space-saving design is beneficial.

Ein Ausführungsbeispiel der Erfindung wird anhand der 1 erläutert. Es zeigen:An embodiment of the invention will be described with reference to 1 explained. Show it:

1 Druckluftbehältereinheit mit Druckbehälter und Wegeventil. 1 Compressed air tank unit with pressure tank and directional control valve.

In 1 ist die Druckluftbehältereinheit mit Druckbehälter 1 und Wegeventil 2 im Halbschnitt dargestellt. Der Druckbehälter 1 umschließt die eingeschlossene und komprimierte Luft 6 in seinem Druckbehälterinnenraum 5. In die Druckbehälterauslassöffnung 3 ist das pneumatisch vorgesteuerte Wegeventil 2 eingeschraubt, welches in der Zeichnung in gesperrter Schaltstellung dargestellt ist. Bei gesperrtem Wegeventil 2 ist die Verbindung zwischen dem Druckbehälterinnenraum 5 und der Auslassöffnung 7 getrennt. Durch Druckluftbeaufschlagung am Steuerluftanschluss 8 des pneumatisch vorgesteuerten Wegeventils 2 öffnet dieses, wodurch die komprimierte Luft 6 vom Druckbehälterinnenraum 5 zur Auslassöffnung 7 strömt und somit die dort angeschlossenen Druckluftverbraucher und/oder Druckluftkreisläufe mit Druckluft versorgt. Das Einspeisen von Druckluft in den Druckbehälter 1 erfolgt mittels einer nicht dargestellten Versorgungsleitung, welche an die Druckbehältereinlassöffnung 4 angeschlossen wird. Alternativ kann Druckluft auch durch das geöffnete Wegeventil 2 eingespeist werden. In der Zeichnung nicht dargestellt ist die Leitung zu den Druckluftverbrauchern und/oder der pneumatische Anlage, welche an die Auslassöffnung (7) angeschlossen wird. Ebenfalls nicht dargestellt sind das Pilotventil zur Ansteuerung des pneumatisch vorgesteuerten Wegeventils (2) und die für den Betrieb von Druckbehältern teils erforderlichen Zusatzausstattungen, wie z. B. ein Überdruckventil.In 1 is the compressed air tank unit with pressure tank 1 and directional valve 2 shown in half section. The pressure vessel 1 encloses the trapped and compressed air 6 in his pressure vessel interior 5 , Into the pressure vessel outlet 3 is the pneumatically pilot operated directional control valve 2 screwed, which is shown in the drawing in locked switching position. With blocked directional control valve 2 is the connection between the pressure vessel interior 5 and the outlet opening 7 separated. By applying compressed air to the control air connection 8th the pneumatically pilot operated directional control valve 2 opens this, reducing the compressed air 6 from the pressure vessel interior 5 to the outlet opening 7 flows and thus supplied there compressed air consumers and / or compressed air circuits supplied with compressed air. Feeding compressed air into the pressure vessel 1 takes place by means of a supply line, not shown, which to the pressure vessel inlet opening 4 is connected. Alternatively, compressed air can also through the open directional control valve 2 be fed. Not shown in the drawing is the line to the compressed air consumers and / or the pneumatic system, which at the outlet opening ( 7 ) is connected. Also not shown are the pilot valve for controlling the pneumatically piloted directional control valve ( 2 ) and for the operation of pressure vessels partly required additional equipment such. B. a pressure relief valve.
