Description
Die Erfindung betrifft ein Mischventil mit einer regelkreisgesteuerten, elektromechanisch betätigten und gegenläufigen Ventilsteuerung des Kalt- und Heißwasserzuflusses, nach Patent 2323841.The invention relates to a mixing valve with a closed-loop control, Electromechanically operated and counter-rotating valve control of the cold and Hot water inflow, according to patent 2323841.
Bei dem Mischventil nach dem Hauptpatent ist der Umstand nachteilig, daß beide Wasserzufuhrleitungen mit einem eigenen Verschlußstück ausgerüstet sind, an deren gemeinsamer Drehachse ein elektrischer Stellmotor mit Getriebe angreift.In the mixing valve according to the main patent, the disadvantage is that both water supply lines are equipped with their own locking piece, on whose common axis of rotation an electrical Servomotor attacks with gear.
Der Erfindung liegl die Aufgabe zugrunde, diesen baulichen Aufwand noch zu v.-.rringe/.i, so daß sich der Gestehungspreis und die Störungsanfälligkeit vermindern. The invention is based on the object of this structural effort still to v .-. rringe / .i, so that reduce the cost price and the susceptibility to failure.
Gelöst wird diese Aufgabe nach der Erfindung bei dem Mischventil der eingangs erwähnten Art durch folgende Kombination teilweise an sich bekannter Merkmale:This object is achieved according to the invention in the mixing valve of the type mentioned at the beginning the following combination of features, some of which are known per se:
a) an der Mündungsstelle der Kalt- und der Heißwasserzufuhrleitung ist ein gemeinsames, gegenläufig wirkendes Verschlußstück angeordnet,a) at the mouth of the cold and hot water supply lines a common, oppositely acting locking piece is arranged,
b) das Verschlußstück ist durch einen regelkreisgesteuerten Drehmagnet verstellbar.b) the closure piece can be adjusted by means of a rotary solenoid controlled by a closed-loop control system.
Durch die CH-Patentschrift 546366 und durch die GB-Patentschrift 1023399 sind zwar vergleichbare Mischventile bekanntgeworden, die ein gemeinsames, gegenläufig wirkendes Verschlußstück für zwei Flüssigkeitsströme haben. Dieses Verschlußstück ist jedoch lediglich von Hand zu verstellen und verfügt über keinerlei elektrisch betätigte eigene Antriebsmittel. In der US-Patentschrift 3206160 wird hingegen ein durch einen elektrischen Drehanker betätigtes Ver-The CH patent specification 546366 and GB patent specification 1023399 are comparable Mixing valves have become known which have a common, oppositely acting closure piece for two liquid flows to have. However, this locking piece can only be adjusted by hand and has no electrically operated own drive means. In US Patent 3206160, however, is a actuated by an electric rotating armature
schlulistück beschrieben, das jedoch nur eine einzige schmale Durchflußbohrung für einen einzigen Flüssigkeitsstrom besitzt, so daß für zwei Flüssigkeitsströme zwei derartige Verschlußstücke erforderlich sind, wogegen gemäß dem erfindungsgemäßen Vorschlag ein einziges gemeinsames Verschlußstück ausreicht. Schlulistück described, but only one narrow flow hole for a single flow of liquid possesses, so that two such closure pieces are required for two liquid flows are, whereas according to the proposal according to the invention, a single common closure piece is sufficient.
Nachfolgend wird an Hand der Zeichnung eine Ausführungsform der Erfindung näher erläutert. Es zeigtAn embodiment of the invention is explained in more detail below with reference to the drawing. It shows
Fig. 1 eine Draufsicht auf das Mischventil mit entfernter Abdeckplatte, etwa in natürlicher Größe undFig. 1 is a plan view of the mixing valve with the cover plate removed, approximately natural size and
Fig. 2 eine Seitenansicht gemäß Schnittlinie I-I in Fig. 1 in Verbindung mit einer ergänzenden Funktionssxizze. Fig. 2 is a side view according to section line I-I in Fig. 1 in connection with a supplementary functional sketch.
Auf der Grundplatte 11 sind neben dem elektronischen Regler 16 die beiden Rohrleitungen 14 und 15 befestigt, in denen die Wasserströme in Richtung der Pfeile 14' und 15' durch das zylinderförmige gemeinsame Verschlußstück 23 fließen. Auf der Drehachse 13 des Verschlußstückes 23 ist der Drehmagnet 17 angeordnet. Der Temperaturfühler 8 ist als Istwertgeber mit dem Potentiometer 19 als Sollwertgeber verbunden. Der Mikroschalter 10 legt an das Magnetventil 45 Spannung an, und das Mengenventil 6 dient zur Regulierung des Wassermengenauslaufs.In addition to the electronic controller 16, the two pipes 14 and 15 are on the base plate 11 attached, in which the water flows in the direction of arrows 14 'and 15' through the cylindrical joint Closure piece 23 flow. The rotary magnet 17 is on the axis of rotation 13 of the closure piece 23 arranged. The temperature sensor 8 is connected as an actual value transmitter to the potentiometer 19 as a setpoint transmitter. The microswitch 10 applies voltage to the solenoid valve 45, and the flow control valve 6 is used for Regulation of the water flow rate.
Die Bewegung des im Mischpunkt drehbaren Verschlußstücks 23 erfolgt durch den Drehmagnet 17, der durch die Reglerendstufe angesteuert wird. Bei dem in Fig. 2 dargestellten Zustand ist der Zufluß »warm« völlig geschlossen und der Zustand »kalt« völlig geöffnet. Wird nun der Sollwert auf eine beliebig wärmere Auslauftemperatur eingestellt, so wird die Spule 22 des Drehmagneten 17 über die Reglerendstufe entsprechend polarisiert. Zwischen dem Permanentmagneten und dem Elektromagneten entstehen somit Kräfte, die den drehbaren Permanentmagneten auslenken und damit synchron das Verschlußstück 23 bewegen. Durch die Drehung des Verschtußstücks 23 wird der Zuflußquerschnitt der Komponente »kalt« verringert und im gleichen Maße die Komponente »'Warm« geöffnet. Die entsprechende Mischtemperatur wird von dem Temperaturfühler 8 sofort registriert und als analoger Widerstand dem elektronischen Regler 16 zugeführt, der die Endstufe so lange ansteuert, bis die gewünschte Mischtemperatur erreicht ist.The movement of the closure piece 23, which is rotatable at the mixing point, is carried out by the rotary magnet 17, the is controlled by the controller output stage. In the state shown in Fig. 2, the inflow is "warm" completely closed and the "cold" state completely open. If the setpoint is now arbitrarily warmer If the outlet temperature is set, the coil 22 of the rotary magnet 17 is activated via the controller output stage polarized accordingly. This creates between the permanent magnet and the electromagnet Forces which deflect the rotatable permanent magnet and thus move the locking piece 23 synchronously. By turning the closure piece 23, the inflow cross-section of the component becomes "cold" and the component "Warm" is opened to the same extent. The corresponding mixing temperature is registered immediately by the temperature sensor 8 and as an analog resistance to the electronic Controller 16 supplied, which controls the output stage until the desired mixing temperature is reached.
Da der elektronische Regler 16 - auf der Basis des Spannungsvergleichs mit Hilfe einer Wheatstoneschen Brücke - nach Differenz Null arbeitet, wird somit auch bei Temperaturschwankungen einer oder beider Komponenten die Auslauftemperatur stets konstant gehalten.Since the electronic regulator 16 - on the basis of the voltage comparison with the help of a Wheatstone Bridge - works according to the difference zero, so even with temperature fluctuations an or of both components, the outlet temperature is always kept constant.
