Abstract
Description
Die Erfindung bezieht sich auf einen Flügelrad-Durchflußmesser gemäß dem Oberbegriff des Anspruches 1.The invention relates to an impeller flow meter according to the preamble of claim 1.
Bei einem bekannten derartigen Durchflußmesser sind die Hall-Sensoren an einem Montageplättchen befestigt, das mit zwei Schrauben an dem Gehäuse befestigt ist.In a known flow meter of this type, the Hall sensors are on one Mounting plate attached, which is attached to the housing with two screws.
Dabei ergibt sich jedoch der Nachteil eines erheblichen Aufwandes bei der Herstellung eines solchen Gehäuses. So ist es erforderlich, Gewinde-Sackbohrungen an dem Gehäuse anzubringen. Außerdem erfordert die Anbringung der Hall-Sensoren an der Außenseite einen erheblichen Montageaufwand. Außerdem muß meist noch ein Schutz gegen mechanische Beschädigungen der Hall-Sensoren vorgesehen werden. Auch dieser Schutz erfordert einen erheblichen Herstellungs- und Montageaufwand.However, there is the disadvantage of considerable effort in the production of a such housing. So it is necessary to have threaded blind holes on the housing to attach. It also requires that the Hall sensors be attached to the outside a considerable assembly effort. In addition, usually protection against mechanical damage to the Hall sensors can be provided. This protection too requires considerable manufacturing and assembly effort.
Ziel der Erfindung ist es, diese Nachteile zu vermeiden und einen Durchflußmesser der eingangs erwähnten Art vorzuschlagen, der sich durch einen einfachen Aufbau auszeichnet.The aim of the invention is to avoid these disadvantages and a flow meter to propose the type mentioned above, which is characterized by a simple structure.
Erfindungsgemäß wird dies bei einem Flügelrad-Durchflußmesser der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht. According to the invention, this is the case with an impeller flow meter of the type mentioned at the beginning Art achieved by the characterizing features of claim 1.
Durch die vorgeschlagenen Maßnahmen ist eine sehr einfache und gegen mechanische Beschädigungen geschützte Anbringung der Hall-Sensoren möglich. Dabei kann die Tasche bei der Herstellung des Gehäuses an dieses einstückig angeformt werden. Besonders leicht läßt sich dies bei gegossenen Gehäusen bewerkstelligen.The proposed measures are very simple and mechanical Damaged, protected attachment of the Hall sensors possible. The bag can be integrally formed on the housing during manufacture. Particularly easy this can be done with cast housings.
Durch die Merkmale des Anspruches 2 ergibt sich der Vorteil, daß ein Hall-Sensor sehr einfach montiert werden kann. Dazu genügt es, den Sensor in die Tasche einzuschieben, wobei dieser einrastet. Zum Demontieren eines Sensors genügt es, die Rastnase zurückzudrücken und den Sensor aus der Tasche zu ziehen.The features of claim 2 have the advantage that a Hall sensor very can be easily assembled. All you have to do is slide the sensor into your pocket, whereby this snaps into place. To remove a sensor, it is sufficient to use the latch push back and pull the sensor out of the pocket.
Durch die Merkmale des Anspruches 3 ergibt sich der Vorteil einer sehr steifen Konstruktion des Gehäuses, wobei die Wandstärke desselben gering gehalten werden kann.The features of claim 3 give the advantage of a very rigid construction of the housing, the wall thickness of which can be kept low.
Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:The invention will now be explained in more detail with reference to the drawing. Show:
Fig. 1 eine Draufsicht auf einen Durchflußmesser und Fig. 1 is a plan view of a flow meter and
Fig. 2. einen Schnitt durch die Kammer eines Durchflußmessers. Fig. 2. shows a section through the chamber of a flow meter.
Gleiche Bezugszeichen bedeuten in beiden Figuren gleiche Einzelteile.The same reference symbols in both figures mean the same individual parts.
Der Durchflußmesser weist zwei Anschlußstutzen 1, 2 auf, die koaxial ausgerichtet sind und von einer gegenüber diesen seitlich versetzten Kammer 3 wegführen.The flow meter has two connecting pieces 1 , 2 which are aligned coaxially and lead away from a chamber 3 which is laterally offset with respect to them.
In dieser Kammer 3 ist eine in zu den Anschlußstutzen 1, 2 im wesentlichen senkrecht verlaufende Achse 4 gehalten, auf der ein Flügelrad 5 drehbar gelagert ist. Dieses Flügelrad 5 ist mit mehreren Magneten 6 versehen. In this chamber 3 , an axis 4 , which is essentially perpendicular to the connecting pieces 1 , 2 and on which an impeller 5 is rotatably mounted, is held. This impeller 5 is provided with a plurality of magnets 6 .
Die Kammer 3 ist, wie aus der Fig. 2 zu ersehen ist, mit einem Deckel 7 abgedeckt.The chamber 3 is, as can be seen from FIG. 2, covered with a cover 7 .
An der Außenseite des Gehäuses 8 ist im Bereich der Kammer 3 eine Tasche 9 angeformt. Die Außenwand 10 der Tasche 9 ist mit einer Rastausnehmung 11 versehen, die zur Aufnahme einer federnden Rastnase 12 dient, die an einem Fühlerkopf 13 angeformt ist. Dieser Fühlerkopf 13 enthält einen Hall-Sensor, der ein Signal abgibt, sobald sich ein Magnet 6 aufgrund einer durch eine Durchströmung der Kammer 3 bedingte Drehung des Flügelrades 5 an dem Hall-Sensor vorbeibewegt.A pocket 9 is formed on the outside of the housing 8 in the region of the chamber 3 . The outer wall 10 of the pocket 9 is provided with a latching recess 11 which serves to receive a resilient latching lug 12 which is integrally formed on a sensor head 13 . This sensor head 13 contains a Hall sensor which emits a signal as soon as a magnet 6 moves past the Hall sensor due to a rotation of the impeller 5 caused by a flow through the chamber 3 .
Diese Signale werden über mit dem Fühlerkopf 13 verbundene Leiter 14 ausgeleitet und einer nicht dargestellte Steuerung zugeführt.These signals are routed via conductors 14 connected to the sensor head 13 and fed to a controller (not shown).
Die Montage des Hall-Sensors, bzw. des Fühlerkopfes 13 erfolgt durch einfaches Einschieben in die Tasche 9, wodurch dessen Rastnase 12 in die Rastausnehmung 11 der Wand 10 der Tasche 9 einrastet.The Hall sensor or the sensor head 13 is mounted by simply pushing it into the pocket 9 , whereby its latching lug 12 snaps into the latching recess 11 of the wall 10 of the pocket 9 .
Zur Demontage des Fühlerkopfes 13 genügt es, die Rastnase 12 in die Rastausnehmung 11 zurückzudrücken und den Fühlerkopf 13 aus der Tasche 9 herauszuziehen.To dismantle the sensor head 13 , it is sufficient to push the locking lug 12 back into the locking recess 11 and to pull the sensor head 13 out of the pocket 9 .
Durch die Unterbringung des Fühlerkopfes 13 in der Tasche 9 des Gehäuses 8 ist dieser gegen mechanische Beschädigungen geschützt.By accommodating the sensor head 13 in the pocket 9 of the housing 8, it is protected against mechanical damage.
Zur Erhöhung der Steifigkeit des Gehäuses 8 ist dieses mit Versteifungsrippen 15 versehen, die sich von den Anschlußstutzen 1, 2 zur Wand 16 der Kammer 3 erstrecken.To increase the rigidity of the housing 8 , this is provided with stiffening ribs 15 which extend from the connecting pieces 1 , 2 to the wall 16 of the chamber 3 .
