Description
Die Erfindung betrifft eine Vorrichtung zum wahlweisen Filtern oder Ablassen der in einem an die Vorrichtung anschließbaren Kreislaufsystem von einer Pumpe geförderten Flüssigkeit, umfassend ein Vorrichtungsgehäuse mit mindestens zwei Anschlußöffnungen zum Anschluß der Vorrichtung an das Kreislaufsystem und mit einer durch ein Verschlußelement verschließbaren Entleerungsöffnung, sowie mit einem in einer Halteeinrichtung gehaltenen Filter, wobei das Verschlusselement durch die Halteeinrichtung des Filters gebildet ist.The invention relates to a device for selectively filtering or discharging in a connectable to the device circuit system by a pump-funded liquid, comprising a device housing having at least two connection openings for connection of the device to the circulatory system and with a closable by a closure element discharge opening, and with a held in a holding device filter, wherein the closure element is formed by the holding means of the filter.
Derartige Vorrichtungen sind insbesondere bei Heizungsanlagen zum Heizen von Gebäuden bekannt. Bei diesen bekannten Vorrichtungen werden mit einer Filtereinrichtung und einer hiervon getrennten Ablaßeinrichtung jedoch zwei separate Komponenten benötigt.Such devices are known in particular for heating systems for heating buildings. In these known devices, however, two separate components are required with a filter device and a separate discharge device.
So ist beispielsweise aus der DE 1 859 229 eine Vorrichtung mit einem herausnehmbaren Siebfilter bekannt. Das Verschlußelement der Entleerungsöffnung ist hierbei jedoch durch einen separaten Deckel gebildet, der vor der Entnahme des Siebes abgeschraubt werden muß.
Durch die zwei voneinander getrennten Komponenten werden aufwendige und relativ umfangreiche Montagearbeiten beim Einbau der zwei von einander getrennten Einrichtungen erforderlich. Ebenso wird durch zwei getrennte Komponenten bei einer Demontage zu Zwecken einer Reinigung, Wartung oder Reparatur der Vorrichtung ein erhöhter Arbeitsaufwand verursacht. Beide Vorgänge sind daher mit hohen Kosten verbunden. Darüber hinaus fallen auch die reinen Materialkosten der Vorrichtung durch die Anordnung von zwei einzelnen Komponenten höher aus. Ferner erhöht sich auch das Gewicht der Vorrichtung und es wird ein entsprechend großer Bauraum für die Anordnung der beiden Komponenten benötigt.For example, DE 1 859 229 discloses a device with a removable sieve filter. The closure element of Emptying opening is here, however, formed by a separate lid, which must be unscrewed before removing the sieve.
The two separate components complex and relatively extensive installation work when installing the two separate devices are required. Likewise, an increased workload is caused by two separate components in a disassembly for purposes of cleaning, maintenance or repair of the device. Both processes are therefore associated with high costs. In addition, the pure material costs of the device by the arrangement of two individual components are higher. Furthermore, the weight of the device also increases and a correspondingly large installation space is required for the arrangement of the two components.
Derartige Vorrichtungen sind auch aus den Dokumenten US-A-4082676, EP-A-0363586 und US-A-790346 bekannt.Such devices are also known from documents US-A-4082676, EP-A-0363586 and US-A-790346.
Aufgabe der vorliegenden Erfindung ist es daher, eine konstruktiv einfache, preiswerte herzustellende und leicht handhabbare Vorrichtung der eingangs genannten Art zu schaffen, die bei geringen Außenabmessungen und geringem Gewicht einfach und schnell zu montieren ist und die als kompakte Einheit sowohl eine Filterung als auch ein Ablassen der geförderten Flüssigkeit ermöglicht.Object of the present invention is therefore to provide a structurally simple, inexpensive to manufacture and easy to handle device of the type mentioned, which is easy and fast to install with small external dimensions and low weight and as a compact unit both filtering and draining allows the pumped liquid.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung nach Anspruch 1 gelöst. Wesentlich ist dabei, daß das Verschlußelement durch die Halteeinrichtung des Filters gebildet und verschiebbar und/oder verschwenkbar in dem Vorrichtungsgehäuse gelagert ist. Dabei übernimmt die Halteeinrichtung sowohl die Aufgabe, den Filter zu halten, als auch die Entleerungsöffnung zu verschließen.This object is achieved by a device according to claim 1. It is essential that the closure element is formed by the holding device of the filter and slidably and / or pivotably mounted in the device housing. In this case, the holding device takes over both the task of holding the filter, and to close the discharge opening.
Der Hauptvorteil liegt dabei darin, daß eine separate Ablaßeinrichtung mit einem eigenen Verschlußelement nicht mehr erforderlich ist. Durch die Integration der Drainage-Funktion (Ablassen der Flüssigkeit) in die Filtereinrichtung wird nicht nur erheblicher Bauraum und Gewicht eingespart, sondern auch die Montagearbeiten beim Anschluß der Vorrichtung sowie gegebenenfalls durchzuführende Demontagearbeiten werden deutlich verringert. Insgesamt sind für beide Funktionen nicht mehr vier Anschlüsse von zwei von einander getrennter Einrichtungen, sondern nur noch zwei Anschlüsse einer kombinierten Vorrichtung erforderlich.
Die Konstruktion ist einfach und die Vorrichtung dadurch leicht handzuhaben und preiswert herzustellen und zu montieren.The main advantage lies in the fact that a separate discharge device with its own closure element is no longer required. By the Integration of the drainage function (draining the liquid) in the filter device not only considerable space and weight is saved, but also the assembly work when connecting the device as well as possibly to be performed disassembly work are significantly reduced. Overall, no longer four ports of two separate devices, but only two ports of a combined device are required for both functions.
The construction is simple and the device thereby easy to handle and inexpensive to manufacture and assemble.
Auf besonders einfache Weise kann die Halteeinrichtung des Filters die beiden Aufgaben erfüllen, da sie erfindungsgemäß verschiebbar und/oder verschwenkbar in dem Vorrichtungsgehäuse gelagert ist. Dabei kann sie die Entleerungsöffnung in einer Position verschließen und in anderen Positionen teilweise oder vollständig freigeben.In a particularly simple manner, the holding device of the filter can perform the two tasks, since it is mounted according to the invention displaceable and / or pivotable in the device housing. It can close the discharge opening in one position and partially or completely release it in other positions.
Besonders vorteilhaft ist es dabei, wenn die Halteeinrichtung vermittels einer Gewindeverbindung verschiebbar ist. Dadurch ist bei einfacher Konstruktion eine besonders exakte Positionierung möglich.It is particularly advantageous if the holding device is displaceable by means of a threaded connection. As a result, a particularly accurate positioning is possible with a simple construction.
In einer bevorzugten Ausführungsform weist die Halteeinrichtung einen Gewindebolzen auf, der in ein Innengewinde eines drehbar an dem Vorrichtungsgehäuse gelagerten Betätigungselementes eingreift. Selbstverständlich ist es in umgekehrter Weise auch möglich, daß der mit dem Außengewinde versehene Bolzen an dem axial fest und drehbar gelagerten Betätigungselement vorgesehen ist, während die Halteeinrichtung des Filters eine Bohrung mit einem entsprechenden Innengewinde aufweist.In a preferred embodiment, the holding device on a threaded bolt which engages in an internal thread of a rotatably mounted on the device housing actuating element. Of course, it is also possible in the reverse manner that the bolt provided with the external thread is provided on the axially fixed and rotatably mounted actuating element, while the holding device of the filter has a bore with a corresponding internal thread.
Besonders vorteilhaft ist es dabei, wenn das Betätigungselement kraft- und/oder formschlüssig lösbar in dem Vorrichtungsgehäuse befestigt ist. Vorzugsweise wird vorgeschlagen, daß das Betätigungselement durch eine Nadelsteckverbindung in dem Vorrichtungsgehäuse gehalten ist. Auf diese Weise ist es besonders einfach möglich, den Filter im Falle einer Verstopfung nach dem Entleeren des kompletten Kreislaufsystems durch Lösen der Nadelsteckverbindung zusammen mit dem Betätigungselement aus der Vorrichtung zu entnehmen, um ihn zu reinigen oder auszutauschen.It is particularly advantageous if the actuator is non-positively and / or positively releasably secured in the device housing. It is preferably proposed that the actuating element is held in the device housing by a needle plug connection. To this It is particularly easy manner to remove the filter in the event of a blockage after emptying the entire circulatory system by releasing the needle connector together with the actuator from the device to clean or replace it.
Eine besonders einfach Konstruktion kann dadurch erreicht werden, daß der Filter in Form eines Hohlzylinders ausgebildet ist, der koaxial zu der Gewindeverbindung ausgerichtet ist.A particularly simple construction can be achieved in that the filter is in the form of a hollow cylinder, which is aligned coaxially with the threaded connection.
Günstig ist es ferner, wenn die Vorrichtung aus Kunststoff gefertigt ist, wodurch bei geringem Gewicht eine besonders einfache Herstellbarkeit gegeben ist.It is also advantageous if the device is made of plastic, whereby a particularly simple manufacturability is given at low weight.
Besonders vorteilhaft ist es außerdem, wenn weitere hydraulische Komponenten, beispielsweise ein Drucksensor und/oder ein Sicherheitsventil in die Vorrichtung integriert ist. Dadurch könnte beispielsweise eine drohende Verstopfung des Filters frühzeitig erkannt werden oder ein unzulässig hoher Systemdruck im Falle eines zu hohen Verstopfungsgrades des Filters vermieden werden.It is also particularly advantageous if further hydraulic components, such as a pressure sensor and / or a safety valve is integrated into the device. As a result, for example, an imminent blockage of the filter could be detected early or an inadmissibly high system pressure can be avoided in the event of a too high degree of clogging of the filter.
Neben dem Einsatz der erfindungsgemäßen Vorrichtung in Heizkreisläufen von Gebäuden ist ein Einsatz in Heiz- und/oder Kühlkreisläufen von Kraftfahrzeugen besonders vorteilhaft. Vorzugsweise kann die Vorrichtung in eine Anschlußvorrichtung zum Anschluß an die Pumpe des Kreislaufsystems integriert sein.In addition to the use of the device according to the invention in heating circuits of buildings, use in heating and / or cooling circuits of motor vehicles is particularly advantageous. Preferably, the device may be integrated into a connection device for connection to the pump of the circulatory system.
Eine weitere besonders bevorzugte Position zur Anordnung der erfindungsgemäßen Vorrichtung ist in einer Hydraulikbaugruppe für eine kombinierte Heizwasser- und Sanitärwasseranlage, mit der Sanitärwasser durch Heizwasser erwärmt werden kann. Dabei kann sie in einen derartigen, beispielsweise aus der DE 196 32 605 bekannten "Hydro-Block" integriert sein.Another particularly preferred position for the arrangement of the device according to the invention is in a hydraulic assembly for a combined heating water and sanitary water system, with the sanitary water can be heated by heating water. It may be integrated in such, for example, from DE 196 32 605 known "hydro-block".

Das Betätigungselement 13 ist über eine besonders einfach und schnell zu montierende und zu demontierende Nadelsteckverbindung 14 in einem am Gehäuse 2 ausgebildeten Stutzen 15 axial festgehalten, so daß eine Drehung des Betätigungselementes 13 zu einer axialen Bewegung der Halteeinrichtung 7 und somit des Filters 6 führt. Das Betätigungselement 13 ist ebenfalls über einen Dichtring 10 gegen den Stutzen 15 abgedichtet. Es kann an seinem unteren freien Ende in vorteilhafter Weise vier- oder sechseckig ausgebildet sein, um mit entsprechenden Werkzeugen eine einfache Verdrehung zu ermöglichen.Below the cylindrical region 8, the
In Höhe des Stutzens 15 weist das Gehäuse eine Entleerungsöffnung 16 auf, die in der zeichnerisch dargestellten Position der Halteeinrichtung 7 durch den Dichtring 10 am zylindrischen Bereich 8 gegenüber dem Kanal 5 abgedichtet ist.
