Description

Die Erfindung betrifft eine lösbare Schnellverbindung als hydraulische Schnittstelle zwischen einer Leitungs-Anschlussstelle insbesondere einer Heizungs- und/oder Kühlanlage eines Gebäudes oder Fahrzeugs und einem ansteckbaren oder anschraubbaren Flüssigkeit führenden Bauteil, wobei die Anschlussstelle als Vorlauf- und Rücklaufleitung zwei Kanäle aufweist, die durch mindestens ein Ventil absperrbar sind, das durch das an der Anschlussstelle befestigbare Bauteil oder ein zusätzliches Stellteil während des Befestigens oder Lösens betätigbar ist.The invention relates to a releasable quick connection as a hydraulic interface between a line connection point, in particular a heating and / or cooling system of a building or vehicle and an attachable or bolted liquid leading component, wherein the connection point as a flow and return line has two channels, by at least a valve can be shut off, which can be actuated by the attachable at the junction component or an additional actuator during the fastening or loosening.

Aus der EP 1 033 495 und EP 1 302 725 sind lösbare Schnellverbindungen insbesondere für kleinere Pumpen bekannt. Der hydraulische Anschluss ist hierbei örtlich von den elektrischen Anschlüssen getrennt. Das Pumpengehäuse hat Anschlüsse für den Einbau in das Medium führende System. Am Elektromotor befinden sich die elektrischen Anschlüsse in der Regel in einem so genannten Klemmenkasten. Diese werden über Klemmen oder Stecker an das elektrische Netz angeschlossen. Üblicherweise werden die elektrischen Verbindungen einer Pumpe nach dem Einbau in das Medium führende System vorgenommen. Dies ist relativ aufwendig und ggf. ist es im Bereich der Haustechnik nötig, diese Arbeiten durch unterschiedliche Fachhandwerker durchführen zu lassen. Ferner erfordert nicht nur das Montieren, sondern auch das Demontieren insbesondere für ein Auswechseln einen erheblichen Arbeitsaufwand. Auch kann es geschehen, dass eine elektrisch angeschlossene Pumpe durch den Motor angetrieben wird, obwohl das/die Ventile nicht geöffnet sind.From the EP 1 033 495 and EP 1 302 725 are releasable quick connections especially for smaller pumps known. The hydraulic connection is locally separated from the electrical connections. The pump housing has connections for installation in the medium leading system. On the electric motor, the electrical connections are usually in a so-called terminal box. These are connected to the electrical network via terminals or plugs. Usually, the electrical connections of a pump are made after installation in the medium-leading system. This is relatively expensive and it may be necessary in the field of building services to have this work carried out by different skilled tradesmen. Furthermore, not only the mounting, but also the dismantling, especially for a replacement requires a considerable amount of work. Also it can happen that an electrically connected Pump is driven by the motor, although the / the valves are not open.

Aufgabe der Erfindung ist es, eine Verbindung der eingangs genannten Art so zu verbessern, dass bei einfacher Konstruktion, Herstellung und Bedienung eine einfache Montage und Demontage bei hoher Funktionssicherheit gegeben ist.The object of the invention is to improve a compound of the type mentioned so that with simple design, manufacture and operation a simple assembly and disassembly is given high reliability.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zusätzlich eine elektrische Schnittstelle zwischen der Anschlussstelle und dem Bauteil angeordnet ist.This object is achieved in that in addition an electrical interface between the connection point and the component is arranged.

Hierdurch wird die hydraulische und elektrische Verbindung gleichzeitig ermöglicht. Es ergibt sich vor allem im Servicefall eine deutliche Vereinfachung beim Aus- und Einbau, bzw. beim Tausch einer Pumpe. Neben der Spannungsversorgung können gleichzeitig auch die elektrischen Verbindungen von Kommunikationsleitungen und/oder Sensoren durchgeführt werden.As a result, the hydraulic and electrical connection is made possible simultaneously. Especially when servicing a clear simplification during removal and installation, or when replacing a pump. In addition to the power supply, the electrical connections of communication lines and / or sensors can be performed at the same time.

Es wird sichergestellt, dass die Pumpe nicht bei geschlossenen Ventilen in Betrieb genommen werden kann. Die elektrische Verbindung ist erst bei geöffneter hydraulischer Verbindung erreicht. In einem zentral gesteuerten System kann darüber hinaus über die elektrische Verbindung festgestellt werden, ob die Pumpe ordnungsgemäß eingebaut und die hydraulische Verbindung hergestellt ist.It is ensured that the pump can not be put into operation when the valves are closed. The electrical connection is reached only when the hydraulic connection is open. In addition, in a centrally controlled system, the electrical connection can be used to determine if the pump is properly installed and the hydraulic connection is made.

Vorteilhafte Weiterentwicklungen der Erfindung sind in den Unteransprüchen aufgeführt.Advantageous further developments of the invention are listed in the subclaims.

Ein Bauteil insbesondere ein Elektromotor 4 mit Pumpeneinheit 2 wird auf das Gehäuse 7 der Anschlussstelle 1 in einer definierten Position aufgesetzt. An dem Anschlussgehäuse 7 und der Pumpeneinheit 2 befinden sich Segmente (Bajonett), welche ineinander greifen und durch ein gegenseitiges Verdrehen in einem bestimmten Winkel, die sich innerhalb des Anschlussgehäuses 7 befindliche Ventile öffnen. Durch diese Drehung werden die Bauteile druckfest und hydraulisch dicht miteinander verbunden. An dem Anschlussgehäuse 7 befindet sich eine elektrische Kontakteinheit 6, welche über ein Kabel 5 mit dem elektrischen Netz verbunden ist. Durch die oben beschriebene Drehung wird gleichzeitig die Verbindung zwischen den Kontakten 3 des Elektromotors 4 mit der Kontakteinheit 6 hergestellt. Sich in dem Motor 4 befindliche Sensoren können ebenfalls auf diese Weise kontaktiert werden.A component, in particular an electric motor 4 with pump unit 2 is placed on the housing 7 of the connection point 1 in a defined position. On the connection housing 7 and the pump unit 2 are segments (bayonet), which mesh with each other and open by a mutual rotation at a certain angle, which are located within the terminal housing 7 valves. By this rotation, the components are pressure-resistant and hydraulically sealed together. At the connection housing 7 is an electrical contact unit 6, which is connected via a cable 5 to the electrical network. By the rotation described above, the connection between the contacts 3 of the electric motor 4 is made with the contact unit 6 at the same time. Sensors in the engine 4 can also be contacted in this way.

Vorzugsweise befinden sich die Kontakte 3 und 6 der Schnittstelle 10 an der Außenseite des Gehäuses 7 und der Pumpe 2 und damit in einem radialen aber gleichen Abstand zur (Dreh-)Achse von Pumpe 2, Motor 4 und Gehäuse 7 sowie der Dichtscheiben des Ventils im Gehäuse 7.Preferably, the contacts 3 and 6 of the interface 10 on the outside of the housing 7 and the pump 2 and thus in a radial but equal distance to the (rotary) axis of the pump 2, motor 4 and housing 7 and the sealing disks of the valve in Housing 7.

Statt einer Motorpumpe 2, 4 kann auch ein anderes Bauteil wie ein Ventil insbesondere ein Thermostatventil, eine Messvorrichtung insbesondere mit Display und/oder ein Sensor mit Gehäuse angeschlossen werden. In weiteren Alternativen weist das anzuschließende Bauteil zwei oder mehr elektrische Spannung führende Teile auf. So können die Pumpe und/oder der Motor Messvorrichtungen und/oder Sensoren aufweisen.Instead of a motor pump 2, 4, another component such as a valve, in particular a thermostatic valve, a measuring device, in particular with display and / or a sensor with housing can be connected. In further alternatives, the component to be connected has two or more electrical voltage-carrying parts. Thus, the pump and / or the motor can have measuring devices and / or sensors.

Ferner kann an der Außenseite des Anschlussgehäuses ein Stellteil insbesondere ein Stellring gelagert sein, durch den das Ventil im Anschlussgehäuse steuerbar und damit zu öffnen und zu schließen ist.Further, on the outside of the terminal housing, an adjusting part, in particular a collar be stored, through which the valve in the connection housing controllable and thus to open and close.
