Description

Die Erfindung betrifft einen Strahlregler mit einer Strahlzerlegeeinrichtung, die den zufließenden Wasserstrom in eine Vielzahl von Einzelstrahlen unterteilt.The invention relates to a jet regulator with a jet disintegrating device which divides the incoming water flow into a plurality of individual jets.

Aus der DE 30 00 799 ist bereits ein Strahlregler bekannt, der eine als Lochplatte ausgestaltete Strahlzerlegeeinrichtung hat. Diese Strahlzerlegeeinrichtung des vorbekannten Strahlreglers unterteilt den zufließenden Wasserstrom in eine Vielzahl von Einzelstrahlen. Die in der Strahlzerlegeeinrichtung gebildeten Einzelstrahlen treffen abströmseitig auf mehrere, einander nachgeschaltete Metallsiebe einer Homogenisiereinrichtung, welche die Einzelstrahlen wieder zu einem homogenen, perlend-weichen Gesamtstrahl formen soll.From the DE 30 00 799 already a jet regulator is known, which has a designed as a perforated plate jet disintegrating device. This jet disintegrating device of the prior art jet regulator divides the incoming water flow into a plurality of individual jets. The individual jets formed in the jet disintegrating device meet on the outflow side to a plurality of metal sieves of a homogenizing device connected downstream of one another, which is intended to reshape the individual jets into a homogeneous, pearly-soft overall jet.

Aus der WO 2004/033807 A1 ist bereits ein belüfteter Strahlregler mit einer Strahlzerlegeeinrichtung bekannt, die den zufließenden Wasserstrom in eine Vielzahl von Einzelstrahlen unterteilt. Dabei ist die Strahlzerlegeeinrichtung derart ausgerichtet, dass die Einzelstrahlen auf jeweils einen Knotenpunkt einander kreuzender Gitterstäbe eines abströmseitig nachgeschalteten Gitternetzes aufprallen. Zum Belüften der Einzelstrahlen sind am Gehäuseumfang des Strahlreglergehäuses mehrere Belüftungsöffnungen vorgesehen. Durch die Belüftungsöffnungen kann die zum Belüften des Wasserstrahls erforderliche Luft angesaugt werden. Dabei besteht jedoch die Gefahr, dass die Luftansaugung und somit die ordnungsgemäße Funktionsweise des vorbekannten Strahlreglers durch den vorbeiströmenden verwirbelten Wasserstrahl beeinträchtigt wird.From the WO 2004/033807 A1 A ventilated jet regulator with a jet disintegrating device is already known, which subdivides the incoming water flow into a plurality of individual jets. In this case, the jet disintegrating device is oriented such that the individual jets impinge on a respective intersection of intersecting bars of a downstream grid network. To ventilate the individual jets several ventilation openings are provided at the housing periphery of the jet regulator housing. Through the ventilation openings required for aerating the water jet air can be sucked. However, there is a risk that the air intake and thus the proper functioning of the prior art jet regulator is affected by the flowing swirling stream of water.

US 4 313 564 beschreibt einen Gegenstand gemäß dem Oberbegriff des Anspruchs 1. US 4,313,564 describes an article according to the preamble of claim 1.

Es besteht die Aufgabe, einen mit vergleichsweise geringem Aufwand herstellbaren Strahlregler der eingangs erwähnten Art zu schaffen, der sich durch eine bessere Zerlegung und Luftbeimischung der zuströmseitigen Einzelstrahlen auszeichnet.It is the object to provide a producible with comparatively little effort jet regulator of the type mentioned above, which is characterized by a better decomposition and air admixing of the inflow side individual beams.

Die erfindungsgemäße Lösung dieser Aufgabe ist im geltenden Patentanspruch 1 beschrieben.The achievement of this object is described in the current claim 1.

Bei dem erfindungsgemäßen Strahlregler trifft zumindest einer der in der Strahlzerlegeeinrichtung gebildeten Einzelstrahlen auf einen Knotenpunkt einander kreuzender Gitterstäbe eines abströmseitig nachgeschalteten Gitternetzes auf. Da zumindest einzelne der vom Strahlzerleger kommenden Einzelstrahlen jeweils auf einen, durch einander kreuzende Gitterstäbe gebildeten Knotenpunkt aufprallen, erfolgt in diesem Bereich jeweils eine weitere mehrachsige Strahlzerlegung jedes Einzelstrahles.In the case of the jet regulator according to the invention, at least one of the individual jets formed in the jet disintegrating device strikes a node of intersecting bars of a grid network connected downstream. Since at least some of the individual beams coming from the beam splitter impact on a node formed by intersecting grids, in each case a further multi-axial beam splitting of each individual beam takes place.

Der erfindungsgemäße Strahlregler ist als belüfteter Strahlregler ausgestaltet, dessen Strahlreglergehäuse an seinem Außenumfang zumindest eine Belüftungsöffnung hat und am Gehäuse-Innenumfang in Strömungsrichtung unterhalb der zumindest einen Belüftungsöffnung einen Abweisvorsprung zum Fernhalten des verwirbelten, d.h. des von den die Einsenkungen umgrenzenden Axialwänden abgelenkten Wasserstrahls von der Belüftungsöffnung, aufweist. Durch die am Gehäuseumfang des Strahlreglergehäuses vorgesehenen Belüftungsöffnungen kann die zum Belüften des Wasserstrahls erforderliche Luft angesaugt werden. Um diese Luftansaugung nicht nur den vorbeiströmenden verwirbelten Wasserstrahl zu beeinträchtigen, ist am Gehäuse-Innenumfang des erfindungsgemäßen Strahlreglers in Strömungsrichtung unterhalb der zumindest einen Belüftungsöffnung ein Abweisvorsprung vorgesehen. Dieser Abweisvorsprung hält den durch das Gehäuseinnere des Strahlreglers durchströmenden verwirbelten Wasserstrahl von den Belüftungsöffnungen fern.The jet regulator according to the invention is designed as a ventilated jet regulator whose jet regulator housing has at least one ventilation opening on its outer periphery and on the housing inner circumference in the flow direction below the at least one ventilation opening a Abweisvorsprung to keep away the swirled, ie the deflected by the depressions Axialwänden the water jet of the Ventilation opening, has. By provided on the housing periphery of the jet regulator housing ventilation holes required for aerating the water jet air can be sucked. In order not to affect this air intake not only the flowing stream of water flowing past, a deflecting projection is provided on the housing inner circumference of the jet regulator according to the invention in the flow direction below the at least one ventilation opening. This deflecting projection keeps the swirling water jet flowing through the housing interior of the jet regulator away from the ventilation openings.

Dabei ist es vorteilhaft, wenn das Gitternetz plattenförmig ausgestaltet ist.It is advantageous if the grid is designed plate-shaped.

Vorteilhaft ist es, wenn die Gitterstäbe zuströmseitig zumindest im Bereich einzelner ihrer Knotenpunkte bereichsweise längsrandseitig gerundet oder abgeschrägt sind. Da bei dieser Ausführungsform die Gitterstäbe zuströmseitig zumindest im Bereich ihrer Knotenpunkte beidseits längsrandseitig gerundet oder abgeschrägt sind, wird eine übermäßige Verwirbelung der Einzelstrahlen vermieden und die Bildung eines homogenen, perlend-weichen Wasserstrahls verbessert.It is advantageous if the grids are rounded or chamfered on the inflow side, at least in the region of some of their nodes, in certain regions along the longitudinal edge. Since, in this embodiment, the bars are rounded or chamfered on both sides along the inflow side at least in the area of their nodal points, excessive swirling of the individual jets is avoided and the formation of a homogeneous, pearly-soft jet of water is improved.

Dabei sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass die Gitterstäbe im Bereich ihrer Knotenpunkte zuströmseitig satteldachförmig abgeschrägt sind.In this case, a preferred embodiment according to the invention provides that the grid bars are chamfered saddle-roof-shaped on the inflow side in the region of their nodes.

Eine besonders vorteilhafte Ausführungsform der Erfindung sieht vor, dass die zuströmseitigen Einsenkungen des Gitternetzes hohlzylindrisch ausgestaltet sind.A particularly advantageous embodiment of the invention provides that the inflow-side depressions of the grid network are configured as hollow cylindrical.

Um den Wasserstrahl über seinen gesamten Strahlquerschnitt gut belüften zu können, ist es vorteilhaft, wenn das Strahlreglergehäuse mehrere, in Umfangsrichtung verteilte Belüftungsöffnungen hat.In order to be able to aerate the water jet well over its entire beam cross-section, it is advantageous if the jet regulator housing has a plurality of circumferentially distributed ventilation openings.

Der erfindungsgemäße Strahlregler kann einen oder mehrere Abweisvorsprünge aufweisen, die jeweils im Bereich einer Belüftungsöffnung vorgesehen sind. Zweckmäßig ist es jedoch, wenn ein Abweisvorsprung am Gehäuse-Innenumfang ringförmig umläuft. Dabei kann der Abweisvorsprung flanschartig ausgestaltet und insbesondere seine der Wasserströmung zugewandten bzw. abgewandten Flachseiten in zueinander etwa parallelen Querschnittsebenen angeordnet sein.The jet regulator according to the invention can have one or more deflecting projections, which are each provided in the region of a ventilation opening. It is expedient, however, if a Abweisvorsprung on the housing inner circumference rotates annular. In this case, the Abweisvorsprung designed flange and in particular its water flow facing or facing away from flat sides may be arranged in approximately parallel cross-sectional planes.

Besonders vorteilhaft ist es jedoch, wenn der Abweisvorsprung auf seine der Belüftungsöffnung in Strömungsrichtung abgewandten Seite eine sich in Strömungsrichtung erweiternde Abweisschräge aufweist. Durch die sich in Strömungsrichtung erweiternde Abweisschräge wird ein im Gehäuseinneren verwirbelter Wasserstrahl von den am Gehäuse-Umfang vorgesehenen Belüftungsöffnungen weg zur Gehäuse-Längsachse geführt.However, it is particularly advantageous if the deflecting projection has a deflection slope widening in the flow direction on its side facing away from the ventilation opening in the direction of flow. Due to the deflection slope widening in the direction of flow, a water jet swirled in the interior of the housing is guided away from the ventilation openings provided on the housing circumference to the housing longitudinal axis.

Um den erfindungsgemäßen Strahlregler modular zusammenstellen zu können, ist es vorteilhaft, wenn das Gitternetz als separates Bauteil in das Gehäuse einsetzbar ist. Somit kann der Strahlregler wahlweise mit oder ohne das erfindungsgemäß ausgestaltete Gitternetz bereitgestellt werden.In order to assemble the jet regulator according to the invention modular, it is advantageous if the grid is used as a separate component in the housing. Thus, the jet regulator can optionally be provided with or without the grid network designed according to the invention.

Die modulare Bauweise des erfindungsgemäßen Strahlreglers wird begünstigt, wenn dem Gitternetz zumindest ein weiteres, in das Gehäuse einsetzbares Bauteil einer Homogenisiereinrichtung und/oder eines Strömungsgleichrichters nachgeschaltet ist.The modular construction of the jet regulator according to the invention is favored if the grid network is followed by at least one further component, which can be inserted into the housing, of a homogenizing device and / or a flow rectifier.

Weiterbildungen gemäß der Erfindung ergeben sich aus den Patentansprüchen sowie der Zeichnung. Nachstehend wird die Erfindung anhand eines Ausführungsbeispieles noch näher beschrieben.Further developments according to the invention will become apparent from the claims and the drawings. The invention will be described below described in more detail with reference to an embodiment.

In den Fig.1 und 5 ist jeweils ein Strahlregler 1 dargestellt, der eine als Lochplatte 2 ausgestaltete Strahlzerlegeeinrichtung hat, die den zufließenden Wasserstrom in eine Vielzahl von Einzelstrahlen unterteilt. Aus den Fig.1 und 5 wird deutlich, dass die in der Strahlzerlegeeinrichtung 2 gebildeten Einzelstrahlen auf jeweils einen Knotenpunkt 3 einander kreuzender Gitterstäbe 4, 5 eines abströmseitig nachgeschalteten Gitternetzes 6 aufprallen. Dabei sind die Gitterstäbe 4 als radiale Stege und die Gitterstäbe 5 als konzentrische Ringwände ausgestaltet. Im Bereich der Knotenpunkte 3 erfolgt eine weitere mehrachsige Zerlegung der zuströmenden Einzelstrahlen.In the Fig.1 and 5 In each case, a jet regulator 1 is shown, which has a designed as a perforated plate 2 jet disintegrating device, which divides the inflowing water flow into a plurality of individual jets. From the Fig.1 and 5 It is clear that the individual beams formed in the beam splitting device 2 impact on a respective intersection 3 of intersecting bars 4, 5 of a downstream grid network 6. The bars 4 are designed as radial webs and the bars 5 as concentric ring walls. In the area of the nodes 3, a further multiaxial decomposition of the incoming individual beams takes place.

Aus einem Vergleich der Fig.1 bis 3 bzw. der Fig.5 bis 7 wird deutlich, dass die Gitterstäbe 4, 5 im Bereich ihrer Knotenpunkte 3 beidseits längsrandseitig abgeschrägt sind. In dem hier dargestellten Ausführungsbeispiel sind die Gitterstäbe 4, 5 im Bereich ihrer Knotenpunkte 3 zuströmseitig satteldachförmig abgeschrägt. Da die Gitterstäbe 4, 5 in diesem Bereich abgeschrägt oder gerundet sind, wird eine übermäßige unerwünschte Verwirbelung der von der Strahlzerlegeeinrichtung 2 kommenden Einzelstrahlen vermieden und die Bildung eines homogenen, perlend-weichen Gesamtstrahles in den Strahlreglern 1 begünstigt.From a comparison of Fig.1 to 3 or the Fig.5 to 7 It is clear that the bars 4, 5 are bevelled in the region of their nodes 3 on both sides along the longitudinal edge side. In the exemplary embodiment illustrated here, the bars 4, 5 are chamfered saddle-roof-shaped in the region of their nodal points 3 on the inflow side. Since the bars 4, 5 are chamfered or rounded in this area, an excessive undesired turbulence of the individual beams coming from the jet disintegrating device 2 is avoided and the formation of a homogeneous, sparkling-soft overall jet in the jet regulators 1 is favored.

In den Fig.1 bis 4 und den Fig.5 bis 8 ist dargestellt, dass die Knotenpunkte 3 jeweils als zuströmseitige Einsenkung des vorzugsweise plattenförmigen Gitternetzes 6 ausgestaltet sind. Dabei sind die zuströmseitigen Einsenkungen des Gitternetzes 6 hohlzylindrisch ausgebildet. Da die Knotenpunkte 3 als Einsenkungen des plattenförmigen Gitternetzes 6 ausgestaltet sind, werden diese Einsenkungen durch die benachbarten Gitterstäbe 4, 5 umgrenzt. In den als Einsenkung des Gitternetzes 6 ausgestalteten Knotenpunkten 3 erfolgt eine weitere sekundäre Zerlegung der von der Lochplatte 2 zuströmenden Einzelstrahlen, da der im Knotenpunkt entlang der Satteldachlinien aufgeteilte Wasserstrahl am Ende der Einsenkung auf die etwa senkrecht zur Satteldachlinie angeordnete und die Einsenkung umgrenzende Wandung trifft. Hierdurch wird der Strahl nochmals zerlegt und abgebremst. Der hier dargestellte Strahlregler 1 zeichnet sich daher durch eine weitestgehende Zerlegung der zuströmenden Einzelstrahlen aus, wobei eine unerwünschte Verwirbelung dieser Einzelstrahlen im Gehäuseinneren des Strahlreglers 1 vermieden wird.In the Fig.1 to 4 and the Fig.5 to 8 it is shown that the nodes 3 are each configured as an inflow-side depression of the preferably plate-shaped mesh 6. In this case, the inflow-side depressions of the mesh 6 are formed as a hollow cylinder. Since the nodes 3 are designed as depressions of the plate-shaped mesh 6, these depressions are bounded by the adjacent bars 4, 5. In the sinking of the Grid 6 configured nodes 3 is carried out a further secondary decomposition of the incoming from the perforated plate 2 individual beams, as the divided at the junction along the saddle roof lines water jet meets at the end of the depression on the approximately perpendicular to the gable roof line and the depression bounding wall. As a result, the beam is again decomposed and decelerated. Therefore, the jet regulator 1 shown here is characterized by a most extensive decomposition of the incoming single jets, whereby an undesirable turbulence of these individual jets inside the housing of the jet regulator 1 is avoided.

Aus den Fig.1 und 5 wird deutlich, dass die hier dargestellten Strahlregler 1 belüftete Strahlregler sind. Die Strahlregler 1 weisen ein Strahlreglergehäuse 7 auf, das an seinem Gehäuseumfang mehrere, in Umfangsrichtung gleichmäßig voneinander beabstandete Belüftungsöffnungen 8 hat. Mit Hilfe der durch das Gehäuseinnere des Strahlreglers 1 fließenden Wasserströmung kann über die Belüftungsöffnungen 8 somit Luft in das Gehäuseinnere eingesaugt werden, die anschließend zur Belüftung des Wasserstrahls verwendet wird.From the Fig.1 and 5 it becomes clear that the jet regulators shown here are 1 aerated jet regulators. The jet regulators 1 have a jet regulator housing 7 which has a plurality of circumferentially uniformly spaced apart ventilation openings 8 at its housing periphery. With the help of flowing through the housing interior of the jet regulator 1 water flow can thus be sucked into the housing interior via the ventilation openings 8, which is then used for ventilation of the water jet.

Aus einem Vergleich der Fig.1 und 4 bzw. Fig.5 und 8 wird deutlich, dass am Gehäuse-Innenumfang in Strömungsrichtung unterhalb der Belüftungsöffnungen 8 ein Abweisvorsprung 9 vorgesehen ist. Dieser Abweisvorsprung 9 läuft am Gitternetz 6 ringförmig um. In den Fig. 1 und 4 ist zu erkennen, dass der ringförmig umlaufende Abweisvorsprung 9 auf seiner den Belüftungsöffnungen 8 in Strömungsrichtung abgewandten Seite eine Abweisschräge 10 aufweist, die sich in Strömungsrichtung erweitert. Demgegenüber ist der hier ebenfalls ringförmig umlaufende Abweisvorsprung 9 bei dem in den Fig.5 bis 8 dargestellten Strahlregler 1 flanschartig ausgestaltet, wobei seine der Wasserströmung zugewandten bzw. abgewandten Flachseiten in zueinander etwa parallelen Querschnittsebenen angeordnet sind. Durch den Abweisvorsprung 9 kann der zu belüftende Wasserstrahl von den im Gehäuseinneren mündenden Belüftungsöffnungen 8 ferngehalten werden. Dabei werden aufwirbelnde Wasserstrahlen mit Hilfe des Abweisvorsprungs 9 und insbesondere mittels der Abweisschräge 10 von den Belüftungsöffnungen 8 weg in Richtung zur Gehäuse-Längsachse des Strahlreglergehäuses 7 geführt.From a comparison of Fig.1 and 4 respectively. Figure 5 and 8th It is clear that a deflecting projection 9 is provided on the housing inner circumference in the flow direction below the ventilation openings 8. This deflecting projection 9 circulates annularly on the grid 6. In the Fig. 1 and 4 It can be seen that the annular circumferential Abweisvorsprung 9 on its side facing away from the ventilation openings 8 in the flow direction side has a Abweisschräge 10, which widens in the flow direction. In contrast, the here also annular circumferential Abweisvorsprung 9 in which in the Fig.5 to 8 illustrated jet controller 1 designed flange-like, with its water flow facing or facing away flat sides are arranged in approximately parallel cross-sectional planes. By Abweisvorsprung 9, the water jet to be ventilated can be kept away from the opening in the housing interior ventilation openings 8. In this case, whirling up water jets are guided by means of the Abweisvorsprungs 9 and in particular by means of Abweisschräge 10 away from the ventilation openings 8 in the direction of the housing longitudinal axis of the jet regulator housing 7.

Aus einem Vergleich der Fig.1 bis 4 sowie der Fig.5 bis 8 wird deutlich, dass das Gitternetz 6 als separates plattenförmiges Bauteil ausgestaltet ist. Das als separates Bauteil ausgestaltete Gitternetz 6 ist in das Strahlreglergehäuse 7 lösbar einsetzbar. Dabei ist dem Gitternetz 6 ein weiteres, in das Gehäuse 7 einsetzbares Bauteil 13 der Homogenisiereinrichtung nachgeschaltet. Das ebenfalls plattenförmig ausgestaltete Bauteil 13 weist mehrere Ringwände 14 auf, die jeweils in der Verlängerung zwischen zwei Knotenpunkten 3 des Gitternetzes 6 angeordnet sind.From a comparison of Fig.1 to 4 as well as the Fig.5 to 8 it is clear that the grid 6 is designed as a separate plate-shaped component. The designed as a separate component grid 6 is detachably inserted into the jet regulator housing 7. In this case, the grid 6 is followed by a further insertable into the housing 7 component 13 of the homogenizer. The also plate-shaped configured component 13 has a plurality of annular walls 14, which are each arranged in the extension between two nodes 3 of the grid 6.

Dem Bauteil 13 ist ein Strömungsgleichrichter 15 nachgeschaltet, der die abströmseitige Stirnseite der Strahlregler 1 bildet. Auch der Strömungsgleichrichter 15 der in den Fig.1 bis 4 bzw. der Fig.5 bis 8 dargestellten Strahlregler 1 weist Ringwände 16 auf, die in Verlängerung der Ringwände 15 des Bauteils 13 angeordnet sind und eine demgegenüber geringfügig kleinere Wandungsstärke aufweisen. Die Ringwände 16 des Strömungsgleichrichters 15 sind an ihrem abströmseitigen Schmalrand gerundet, um die Bildung eines homogenen Gesamtstrahles zu begünstigen. Zu dem gleichen Zweck ist am abströmseitigen Gehäuserand im Strömungsgleichrichter 15 eine ringförmig umlaufende Gehäuseeinschnürung 17 vorgesehen.The component 13 is followed by a flow rectifier 15, which forms the downstream end of the jet regulator 1. Also, the flow rectifier 15 of the in the Fig.1 to 4 or the Fig.5 to 8 illustrated jet regulator 1 has annular walls 16 which are arranged in extension of the annular walls 15 of the component 13 and have a contrast slightly smaller wall thickness. The annular walls 16 of the flow rectifier 15 are rounded at their downstream narrow edge to promote the formation of a homogeneous total beam. For the same purpose, an annular circumferential constriction 17 is provided on the downstream housing edge in the flow rectifier 15.

Aus Fig.1 ist erkennbar, dass das Strahlreglergehäuse 7 der Strahlregler 1 im wesentlichen zweiteilig ausgestaltet ist. Das in einer quer zur Strömungsrichtung orientierten Trennebene unterteilte Strahlreglergehäuse 7 weist ein zuströmseitiges sowie ein abströmseitiges Gehäuseteil 18, 19 auf, die lösbar miteinander verrastbar sind, - aber auch zusätzlich dichtend verschweißt oder dergleichen verbunden werden können.Out Fig.1 It can be seen that the jet regulator housing 7 of the Jet regulator 1 is designed substantially in two parts. The jet regulator housing 7, which is subdivided in a plane of separation oriented transversely to the direction of flow, has an inflow-side and an outflow-side housing part 18, 19, which can be latched to one another in a releasable manner, but can also be sealingly welded or the like connected.

In den Fig.1 und 5 ist dargestellt, dass den Strahlreglern 1 zuströmseitig ein im wesentlichen kegelförmiges Vorsatzsieb vorgeschaltet ist, welches im Wasserstrahl mitgeführte Schmutzpartikel aussondern und von den Strahlreglern 1 fernhalten soll. Das Vorsatzsieb 20 ist an der zuströmseitigen Gehäuse-Stirnseite des Strahlreglergehäuses 7 lösbar verrastbar. In the Fig.1 and 5 It is shown that the jet regulators 1 on the inflow side upstream of a substantially conical auxiliary sieve, which is to separate entrained in the water jet dirt particles and to keep away from the jet regulators 1. The front screen 20 is releasably latched to the inflow-side housing end face of the jet regulator housing 7.
