Since the cross-sectional constriction in the manner of a Venturi nozzle acts and causes the above-described pressure difference between the Aus- and Einfädelötechnisch, directed by the Ausfädelö réelle to the threading flow when removing drinking or service water.
- the generated flow is therefore directional.
- This is the from the DE 39 19 074 A1 previously known connection fitting for drinking or service water systems unsuitable, in which a flow through the strand is provided as needed in one or the other direction.
- connection fitting differs from the above-described connection fitting substantially in that the threading is provided in the region of a diffuser and the recirculation flow recirculated from the loop line is introduced at an angle of not more than 75 ° to the main flow direction.
- This connection fitting is also unsuitable for a drinking or service water system with intended flow reversal, as in the case of flow reversal desired in the loop purge effect is drastically reduced or no longer exists, so that a flushing of subsequent connected to the strand loops can not be guaranteed safely.
- Such a flow reversal can occur when the floor or riser pipe is also formed as a ring and the removal of drinking or service water in one of the connected to the floor or riser ring lines a flow in both the upstream and the downstream Connecting fittings causes.

In other words, when removing drinking or service water to a consumer all in the flow direction in front of the strand connected ring lines can be flushed. It has been found to be advantageous that a conditional by the inventive arrangement of the inlet and Ausfädelö réelle pressure loss within the connection fitting, whereby several in the main flow direction one behind the other arranged connection fittings are tunable to each other taking into account a prevailing operating pressure in the strand, so that a sufficient Flushing effect of all loops remains guaranteed.

In this way, a pressure difference adapted to different volume flows for generating a loop flow can be achieved in a simple manner.
- the closure body closes the cross-sectional constriction at low flow rates up to a critical volume flow substantially sealing.
- a critical volume flow is understood as meaning a volume flow which is sufficient to move the closure body in the main flow direction solely on the basis of frictional and compressive forces acting on the closure body.

Abstract
Description
Die vorliegende Erfindung betrifft eine Anschlussarmatur mit den Oberbegrifflichen Merkmalen von Anspruch 1, wie sie aus der
Im Bereich von Trink- oder Brauchwassersystemen ist es insbesondere zur Vermeidung von Verkeimung in den Trink- oder Brauchwasserleitungen bekannt, eine Anschlussarmatur der vorerwähnten Art vorzusehen, um in einer über diese Anschlussarmatur angeschlossene Ringleitung bei Entnahme von Trink- oder Brauchwasser über einen in Strömungsrichtung nachfolgend angeordneten Verbraucher eine Ringleitungsströmung zu erzielen. Dabei wird eine Teilströmung des Stranges an der Ausfädelöffnung der Anschlussarmatur herausgeleitet und über die Ringleitung zu dem wenigstens einen an der Ringleitung angeschlossenen Verbraucher geführt. Die Ringleitung mündet in der Einfädelöffnung der Anschlussarmatur. In Hauptströmungsrichtung ist der Einfädelöffnung eine Querschnittsverengung vorgelagert, die nach Art einer Düse wirkt und zwischen der Aus- und Einfädelöffnung eine Druckdifferenz bewirkt, durch welche bei einer Strömung in dem Strang auch in der Ringleitung eine Strömung erzeugt wird. Die Hauptströmungsrichtung ist im Sinne der vorliegenden Erfindung synonym zur axialen Erstreckungsrichtung des Stranges zu verstehen. Als Strang im Sinne der vorliegenden Erfindung wird jede Hauptleitung verstanden, unabhängig davon, ob diese sich innerhalb eines Stockwerkes erstreckt und innerhalb des Stockwerkes mehrere hintereinander angeordnete Nasszellen über jeweils eine Ringleitung mit Trink- oder Brauchwasser versorgt, oder als Steigrohrschrank beispielsweise in mehreren Stockwerken übereinander liegende Nasszellen miteinander verbindet.In the field of drinking or service water systems, it is known in particular to avoid contamination in the drinking or service water lines to provide a connection fitting of the aforementioned type to arranged in a connected via this connection fitting ring line when removing drinking or service water via a downstream flow direction Consumer to achieve a loop flow. In this case, a partial flow of the strand is led out at the Ausfädelöffnung the connection fitting and passed over the ring line to the at least one connected to the ring line consumer. The ring line opens into the threading of the connection fitting. In the main flow direction of the threading is preceded by a cross-sectional constriction, which acts in the manner of a nozzle and between the discharge and Einfädelöffnung causes a pressure difference, through which a flow is generated in a flow in the strand in the ring line. For the purposes of the present invention, the main flow direction is to be understood as synonymous with the axial extension direction of the strand. As a strand in the context of the present invention, each main line is understood, regardless of whether this extends within a floor and within the floor several successively arranged wet cells supplied via a ring line with drinking or service water, or as riser cabinet, for example, in several stories superimposed Connecting wet cells with each other.

Die aus der
Der vorliegenden Erfindung liegt das Problem zugrunde, eine Anschlussarmatur zum Anschließen einer Ringleitung mit mindestens einem Verbraucher an einem Stockwerks- bzw. Steigrohrstrang oder Ring anzugeben, mit der ein zuverlässiger Durchspülungseffekt der Ringleitung auch bei Strömungsumkehr erzielt werden kann, und ein Trink- oder Brauchwassersystem bereitzustellen, welches eine solche Anschlussarmatur verwendet.The present invention is based on the problem of specifying a connection fitting for connecting a ring line with at least one consumer on a floor or riser or ring, with a reliable flushing effect of the loop can be achieved even with flow reversal, and to provide a drinking or domestic water system which uses such a connection fitting.
Zur Lösung des obigen Problems wird mit der vorliegenden Erfindung eine Anschlussarmatur mit den Merkmalen von Anspruch 1 und ein Trink- oder Brauchwassersystem mit den Merkmalen von Anspruch 15 vorgeschlagen. Die erfindungsgemäße Anschlussarmatur zeichnet sich gegenüber der gattungsgemäßen Anschlussarmatur durch eine Einfädelöffnung, die im Bereich der einen Querschnittserweiterung und/oder unmittelbar an dieser auf der der Querschnittsverengung gegenüberliegenden Seite angrenzend angeordnet ist, und durch eine Ausfädelöffnung aus, die im Bereich der anderen Querschnittserweiterung und/oder an dieser auf der der Querschnittsverengung gegenüberliegenden Seite unmittelbar angrenzend angeordnet ist. Die erfindungsgemäße Anordnung der Ein- und Ausfädelöffnung erlaubt eine Durchströmung der Anschlussarmatur in beide Richtungen derart, dass ein gewünschter Durchspülungseffekt der Ringleitungen unabhängig von der in dem Strang vorherrschenden Strömungsrichtung sichergestellt bleibt. Mit anderen Worten können bei Entnahme von Trink- oder Brauchwasser an einem Verbraucher sämtliche in Strömungsrichtung davor an den Strang angeschlossene Ringleitungen durchspült werden. Dabei hat es sich als vorteilhaft herausgestellt, dass ein durch die erfindungsgemäße Anordnung der Ein- und Ausfädelöffnung bedingter Druckverlust innerhalb der Anschlussarmatur minimierbar ist, wodurch mehrere in Hauptströmungsrichtung hintereinander angeordnete Anschlussarmaturen aufeinander unter Berücksichtigung eines in dem Strang vorherrschenden Betriebsdruckes abstimmbar sind, so dass ein ausreichender Durchspülungseffekt sämtlicher Ringleitungen gewährleistet bleibt. Insbesondere hat es sich als vorteilhaft zur Verminderung der Druckdifferenz erwiesen, die Einfädelöffnung in Hauptströmungsrichtung in einem Bereich unmittelbar hinter der Querschnittserweiterung anzuordnen, sprich in einem Bereich, in welchem üblicherweise zu erwarten wäre, dass der Leitungsdruck dem Druck an der Ausfädelöffnung entspricht, womit eine Durchspülung der Ringleitung mangels Druckdifferenz nicht erreichbar wäre. Es hat sich aber herausgestellt, dass die Strömung in dem unmittelbar hinter der Querschnittserweiterung liegendem Bereich einen niedrigeren Druck als an der Ausfädelöffnung aufweist, so dass eine Druckdifferenz erreichbar ist, die einen Durchspülungseffekt der Ringleitung gewährleisten kann. Im Einzelnen wirkt die der Einfädelöffnung vorgelagerte Querschnittsverengung als Düse, wodurch die Strömung in den nachgeordneten Diffusor mit erhöhter Geschwindigkeit eingeleitet wird. Obwohl die Strömungsgeschwindigkeit im Diffusor abnimmt, strömt ein bestimmter Anteil der Strömung mit erhöhter Strömungsgeschwindigkeit in den unmittelbar hinter dem Diffusor liegenden Bereich und nimmt in seiner Strömungsgeschwindigkeit erst in einem diesem nachfolgenden Bereich auf eine zu der übrigen Strangströmung korrespondierenden Strömungsgeschwindigkeit ab. Einhergehend mit der erhöhten Strömungsgeschwindigkeit dieser Teilströmung ist der Druck niedriger als an der Ausfädelöffnung, wodurch ein die Durchspülung der Ringleitung bewirkender Unterdruck an der in diesem Bereich angeordneten Einfädelöffnung resultiert. Da die Druckdifferenz allerdings gering ist, sollte vorzugsweise ein durch die Ringleitung auf die Ringleitungsströmung wirkender Strömungswiderstand unter Berücksichtigung der Ringleitungs-Ausgestaltung, beispielsweise durch Anpassung der Oberflächenbeschaffenheit der Ringleitungs-Innenwandung, der Ringleitungslänge, der Anzahl an Krümmungen oder Kanten minimiert werden, um so einem Erliegen der Ringleitungsströmung vorzubeugen.To solve the above problem, the present invention proposes a connection fitting having the features of
In einer bevorzugten Ausgestaltung der vorliegenden Erfindung ist die Einfädelöffnung derart ausgebildet, dass die aus der Ringleitung zurückgeführte Ringleitungsströmung unter einem Einströmwinkel von nicht mehr als 75° zur Hauptströmungsrichtung einströmt. Vorzugsweise beträgt der Einströmwinkel zwischen 35° und 55° zur Hauptströmungsrichtung. Unter Berücksichtigung der vorgenannten Einströmwinkel können eine Vielzahl von Anschlussarmaturen in einem Strang in Strömungsrichtung hintereinander angeordnet werden, die jeweils für sich bei einer Durchströmung des Stockwerk- oder Steigrohrstranges eine Durchspülung der Ringleitung bewirken, ohne dass ein übermäßiger Betriebsdruck in dem Rohrleitungssystem aufgewendet werden muss. Die Strömung wird dabei mit relativ geringer Druckdifferenz durch jede einzelne Armatur im Bereich des Stranges, d.h. der Hauptströmung geführt und beim Zurückführen von der Ringleitung in den Strang strömungsgünstig und verlustarm zurückgeführt. Besonders bevorzugt beträgt der Einströmwinkel zwischen 42° und 47° bezogen auf die Hauptströmungsrichtung, womit sich für eine relativ zu der Hauptströmungsrichtung ausgerichtete zurückgeführte Ringleitungsströmung ein relativ geringer Druckverlust an der Einfädelöffnung ergibt.In a preferred embodiment of the present invention, the threading opening is designed in such a way that the loop stream recirculated from the ring pipe flows in at an inflow angle of not more than 75 ° to the main flow direction. The inflow angle is preferably between 35 ° and 55 ° to the main flow direction. Taking into account the aforementioned inflow, a plurality of connection fittings in a strand in the flow direction can be arranged one behind the other, each effect a flushing of the loop in a flow through the floor or riser without an excessive operating pressure must be expended in the piping system. The flow is thereby with relatively small pressure difference through each individual armature in the region of the strand, i. the main flow out and returned when returning from the loop in the strand streamlined and low loss. Particularly preferably, the inflow angle between 42 ° and 47 ° relative to the main flow direction, which results in a relatively low pressure loss at the threading opening for a relative to the main flow direction aligned recirculated loop flow.
In einer weiteren bevorzugten Ausgestaltung der vorliegenden Erfindung ist die erfindungsgemäße Anschlussarmatur zumindest hinsichtlich der Ausgestaltung der Querschnittserweiterung und der Ein- und Ausfädelöffnungen symmetrisch zu wenigstens einer Mittelpunktachse der Querschnittsverengung ausgebildet. Insbesondere sind die eine Strömung führenden und einen Strömungsquerschnitt ausbildenden Bereiche der Querschnittserweiterungen und der Ein- und Ausfädelöffnungen symmetrisch zu beispielsweise einer vertikal zur Hauptströmungsrichtung liegenden Mittelpunktachse der Querschnittsverengung auszuformen, um für beide Hauptströmungsrichtungen eine im Wesentlichen identische Druckdifferenz zwischen der Ein- und Ausfädelöffnung zur Erzeugung einer Ringleitungsströmung vorsehen zu können.In a further preferred embodiment of the present invention, the connection fitting according to the invention is formed symmetrically with respect to at least one center axis of the cross-sectional constriction, at least with regard to the configuration of the cross-sectional widening and the entry and Ausfüelöffnungen. In particular, the flow leading and forming a flow cross-sectional areas of the cross-sectional enlargements and the inlet and Ausfädelöffnungen symmetrical to form, for example, a lying perpendicular to the main flow direction center axis of the cross-sectional constriction in order for both main flow directions, a substantially identical pressure difference between the input and Ausfädelöffnung to produce a Provide loop flow.
Gemäß einer weiteren bevorzugten Ausgestaltung der vorliegenden Erfindung umfasst die Anschlussarmatur einen in der Querschnittsverengung angeordneten und in Hauptströmungsrichtung verschieblichen Verschlusskörper. Mit dem Verschlusskörper lässt sich beispielsweise eine Strömungsdurchtrittsfläche in der Querschnittserweiterung derart variabel einstellen, dass eine zwischen dem Verschlusskörper und einer Innenwandung der Querschnittsverengung ausgebildete Durchtrittsfläche durch Verschieben des Verschlusskörpers in oder entgegen der Hauptströmungsrichtung vergrößert bzw. verkleinert werden kann. Damit lässt sich eine zu verschiedenen Volumenströmen angepasste Druckdifferenz zur Erzeugung einer Ringleitungsströmung auf einfache Weise erreichen.According to a further preferred embodiment of the present invention, the connection fitting comprises a closure body arranged in the cross-sectional constriction and displaceable in the main flow direction. With the closure body, for example, a flow passage area in the cross-sectional widening can be variably adjusted such that a passage area formed between the closure body and an inner wall of the cross-sectional constriction can be displaced by displacing the closure body can be increased or decreased in or against the main flow direction. In this way, a pressure difference adapted to different volume flows for generating a loop flow can be achieved in a simple manner.
Nach einer weiteren bevorzugten Ausgestaltung der vorliegenden Erfindung verschließt der Verschlusskörper die Querschnittsverengung bei kleinen Volumenströmen bis zu einem kritischen Volumenstrom im wesentlichen dichtend. Unter einem kritischen Volumenstrom wird im Sinne der vorliegenden Erfindung ein solcher Volumenstrom verstanden, der ausreicht, den Verschlusskörper allein aufgrund von auf den Verschlusskörper wirkenden Reibungs- und Druckkräften in Hauptströmungsrichtung zu bewegen. Die vorgenannte Ausgestaltung hat sich in der Hinsicht als vorteilhaft erwiesen, dass bei einer zu erwartenden, geringen Druckdifferenz zwischen Ein- und Ausfädelöffnung bei Entnahme von Trink- oder Brauchwasser der in die Anschlussarmatur vollständig einströmende Volumenstrom durch die Ringleitung geleitet wird. Somit wird auf einfache Weise sichergestellt, dass auch im Falle einer unzureichenden Druckdifferenz zwischen Ein- und Ausfädelöffnung zur Erzeugung einer Ringleitungsströmung bei Entnahme von Trink- oder Brauchwasser ein Durchspülungseffekt in dieser und in weiteren an den Stockwerks- bzw. Steigrohrstrang angeschlossenen Ringleitungen erzielt werden kann.According to a further preferred embodiment of the present invention, the closure body closes the cross-sectional constriction at low flow rates up to a critical volume flow substantially sealing. For the purposes of the present invention, a critical volume flow is understood as meaning a volume flow which is sufficient to move the closure body in the main flow direction solely on the basis of frictional and compressive forces acting on the closure body. The aforementioned embodiment has proven to be advantageous in the respect that is passed at an expected low pressure difference between inlet and Ausfädelöffnung upon removal of drinking or service water in the connection fitting completely inflowing flow through the loop. Thus, it is ensured in a simple manner that even in the case of an insufficient pressure difference between inlet and Ausfädelöffnung for generating a loop flow when removing drinking or service water a flushing effect in this and in other connected to the floor or riser ring loops can be achieved.
Vorzugsweise ist der Verschlusskörper ellipsenförmig ausgebildet. Dadurch kann eine zwischen dem Verschlusskörper und der Innenwandung der Querschnittsverengung ausgebildete Kontaktfläche im Falle eines dichten Verschlusses vergrößert werden, um so einerseits die Dichtigkeit zwischen dem Verschlusskörper und Querschnittsverengung weiter zu verbessern und andererseits den kritischen Volumenstrom in Abhängigkeit der zwischen dem Verschlusskörper und der Innenwandung der Querschnittsverengung wirkenden Reibungskraft und der von dem Volumenstrom ausgehenden Druckkraft geeignet einzustellen.Preferably, the closure body is elliptical. In this way, a contact surface formed between the closure body and the inner wall of the cross-sectional constriction can be increased in the event of a tight closure in order to further improve the tightness between the closure body and the cross-sectional constriction on the one hand and the critical volume flow as a function of the between the closure body and the inner wall of the cross-sectional constriction acting frictional force and emanating from the volume flow pressure force suitable.
Weiter bevorzugt wirkt der Verschlusskörper mit wenigstens einer in Hauptströmungsrichtung wirkenden Rückholfeder zusammen. So kann der Verschlusskörper auf einfache Weise in Hauptströmungsrichtung verschoben oder bei Nachlassen des Volumenstromes in seine Ausgangsposition zurückgeschoben werden, wobei sich die zwischen dem Verschlusskörper und der Innenwandung der Querschnittsverengung und Querschnittserweiterung ausgebildete Durchtrittsfläche dynamisch in Abhängigkeit des Volumenstromes geeignet eingestellt. Zudem ist ein zum Bewegen des Verschlusskörpers notwendiger kritischer Volumenstrom über den Betrag der Federkraft der Rückholfeder vorsehbar.More preferably, the closure body cooperates with at least one return spring acting in the main flow direction. Thus, the closure body can be moved in a simple manner in the main flow direction or pushed back to its original position upon release of the volume flow, wherein the formed between the closure body and the inner wall of the cross-sectional constriction and cross-sectional enlargement passage area adjusted dynamically depending on the volume flow. In addition, a necessary for moving the closure body critical volume flow over the amount of the spring force of the return spring is providable.
Besonders bevorzugt liegt ein Angriffspunkt der Rückholfeder an dem Verschlusskörper in einer parallel zur Hauptströmungsrichtung verlaufenden Symmetrieachse des Verschlusskörpers und vorzugsweise wirkt eine von der Rückholfeder ausgehende Kraft entlang dieser Symmetrieachse. Dadurch wird einer Verkantung des zu verschiebenden Verschlusskörpers begegnet, womit der Verschlusskörper leichter in und/oder entgegengesetzt der Hauptströmungsrichtung verschoben werden kann.Particularly preferably, a point of application of the return spring on the closure body lies in a symmetry axis of the closure body running parallel to the main flow direction, and preferably a force originating from the return spring acts along this axis of symmetry. As a result, a tilting of the closure body to be displaced is encountered, with which the closure body can be displaced more easily in and / or opposite to the main flow direction.
Nach einer weiteren bevorzugten Ausgestaltung der vorliegenden Erfindung greift an den jeweiligen in Hauptströmungsrichtung liegenden Enden des Verschlusskörpers wenigstens eine Rückholfeder an, wobei die in Hauptströmungsrichtung wirkende resultierende Kraft der Rückholfeder bei Strömungslosigkeit gleich Null ist. Der Verschlusskörper kann somit bei Strömungslosigkeit sicher in seiner Ausgangsposition gehalten werden. Ferner können vorspannfreie und/oder vorgespannte Rückholfedern verwendet werden. Weiterhin kann ein Ort der zwischen dem Verschlusskörper und der Innenwandung der Querschnittsverengung ausgebildeten Kontaktfläche derart gewählt werden, dass dieser näher an der einen oder an der anderen Querschnittserweiterung oder gleichmäßig beabstandet zu diesen liegt. Dadurch kann insbesondere ein für beide Hauptströmungsrichtungen unterschiedlich zueinander festgelegter kritischer Volumenstromwert vorgesehen werden. Auch kann ein bis zum Erreichen einer die Querschnittsverengung passierende Durchlassströmung vorgesehener Zeitraum im Bedarfsfall angepasst werden.According to a further preferred embodiment of the present invention, at least one return spring acts on the respective ends of the closure body lying in the main flow direction, the resultant force of the return spring acting in the main flow direction being equal to zero in the event of flowlessness. The closure body can thus be securely held in its initial position in flowless. Furthermore, preload-free and / or preloaded return springs can be used. Furthermore, a location of the contact surface formed between the closure body and the inner wall of the cross-sectional constriction can be chosen such that it is closer to or evenly spaced at one or the other cross-sectional widening. As a result, it is possible in particular to provide a critical volume flow value which is determined differently for each of the two main flow directions. It is also possible, if required, to adjust a period of time provided until the passage of flow passing through the cross-sectional constriction is reached.
Weitere bevorzugte Ausgestaltungen sind durch solche Anschlussarmaturen gekennzeichnet, die parallel zur Hauptströmungsrichtung ein Rohr aufnehmen können. Dieses Rohr wird verwendet, um die Rückführleitungen von Ringleitungen, z.B. die Zirkulationsleitung von Trinkwasser warm, auszubilden. Ebenso können Trinkwasser kalt Ringleitungen auf diese Art und Weise effizient aufgebaut werden.Further preferred embodiments are characterized by such connection fittings, which can receive a pipe parallel to the main flow direction. This tube is used to connect the return lines of loop lines, e.g. the circulation pipe of drinking water warm, train. Likewise, drinking water cold ring lines can be constructed efficiently in this way.
