Description

Die Erfindung betrifft eine Vorrichtung zum Mischen von heißem Wasserdampf und kaltem Wasser mit einem statischen Mischer, dem über Ventile Dampf und Wasser zugeführt werden.The invention relates to a device for mixing hot steam and cold water with a static mixer, to which steam and water are supplied via valves.

Es sind Mischbatterien zum Herstellen von Warmwasser aus Dampf und Kaltwasser bekannt, die beim Abfallen des Wasserdrucks Dampf ungehindert ausströmen lassen, so daß der Benutzer verletzt werden kann. Auch können Schäden an temperaturempfindlichen Stoffen oder Einrichtungen verursacht werden. Ferner führen diese Mischbatterien zu einer schlechten Nutzung hochwertiger Energie.Mixer taps for producing hot water from steam and cold water are known which allow steam to flow out unhindered when the water pressure drops, so that the user can be injured. Damage to temperature-sensitive substances or equipment can also be caused. Furthermore, these mixer taps lead to poor use of high-quality energy.

Darüberhinaus sind Mischbatterien bekannt, die das unkontrollierte Austreten von Dampf bei einem Abfall des Wasserdrucks verhindern. Bei diesen Mischbatterien ist der Steuermechanismus infolge seiner im Medium liegenden Lagerstellen empfindlich und es bedarf einer regelmäßigen Wartung, um die Funktionsfähigkeit zu gewährleisten.In addition, mixer taps are known which prevent the uncontrolled escape of steam when the water pressure drops. With these mixer taps, the control mechanism is sensitive due to its bearing points in the medium and regular maintenance is required to ensure functionality.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Mischen von Wasserdampf und Wasser zu schaffen, die bei einem Abfallen des Wasserdrucks ein Ausströmen von Dampf sicher verhindert und deren Steuermechanismus umempfindlich gegen Ablagerungen ist.The object of the invention is a device for mixing of water vapor and water, which reliably prevents the escape of steam when the water pressure drops and whose control mechanism is sensitive to deposits.

Diese Aufgabe wird erfindungsgemäß daurch gelöst, daß ein die Dampfzufuhr steuerndes Ventil durch den Wasserdruck in der Weise gesteuert ist, daß es erst ab einem Wasserdruck bestimmter Höhe geöffnet und bei zu niedrigem Wasserdruck geschlossen wird.This object is achieved in that a valve controlling the steam supply is controlled by the water pressure in such a way that it is only opened from a water pressure of a certain height and is closed when the water pressure is too low.

Die Mischvorrichtung verhindert mit hoher Sicherheit, daß Wasserdampf dann austritt, wenn der Druck des kalten Wassers nicht ausreichend ist. Die Vorrichtung weist dabei eine einfache und störunanfällige Konstruktion auf. Es bestehen keine empfindliche Lagerstellen und Ablagerungen führen nicht zu Störungen. Die gesamte Vorrichtung weist geringe Außenabmessungen auf und kann darüberhinaus von geringem Gewicht sein.The mixing device prevents with high certainty that water vapor escapes when the pressure of the cold water is insufficient. The device has a simple and failure-prone construction. There are no sensitive bearing points and deposits do not lead to malfunctions. The entire device has small external dimensions and can also be of low weight.

Die Sicherheit der Vorrichtung wird weiter dadurch erhöht, wenn das die Dampfzufuhr steuernde Ventil bei zu geringem Wasserdruck schließbar ist.The safety of the device is further increased if the valve controlling the steam supply can be closed when the water pressure is too low.

Eine konstruktiv besonders einfache Vorrichtung von hoher Zuverlässigkeit wird dadurch erreicht, daß das die Dampfzufuhr steuerende Ventil einen Faltenbalg aufweist, der mit dem Ventilstellglied verbunden ist und an dem Wasserdruck anliegt.A structurally particularly simple device of high reliability is achieved in that the valve controlling the steam supply has a bellows, which is connected to the valve actuator and is applied to the water pressure.

Ferner wird vorgeschlagen, daß zur Verhinderung eines Eindringens von Dampf in die Wasserzufuhrleitung zwischen Mischer und Wasserzufuhrleitung ein Rückschlagventil angeordnet ist. Hierbei kann das Rückschlagventil als Stellglied eine frei bewegliche Kugel aufweisen. Alternativ kann aber auch das Verstellglied des Rückschlagventils federbelastet sein.It is also proposed that a check valve is arranged between the mixer and the water supply line in order to prevent steam from penetrating into the water supply line. Here, the check valve can have a freely movable ball as an actuator. Alternatively, however, the adjusting element of the check valve can also be used be spring loaded.

Eine leichte Bedienbarkeit als aber auch eine hohe Zuverlässigkeit und Sicherheit werden dadurch erreicht, daß in der Wasserzufuhrleitung und in der Dampfzufuhrleitung je ein Ventil angeordnet ist, deren Ventilverstellglieder durch ein gemeinsames Gestänge betätigbar sind. Hierbei kann das Gestänge eine Verstelleinrichtung aufweisen, durch die das Öffnungsverhältnis der Ventile veränderbar ist, so daß der Temperaturgradient des Vorlaufs und des Nachlaufs des Warmwassers in optimaler Weise an den Verbraucher angepaßt werden kann. Vorzugsweise wird vorgeschlagen, daß zum Einstellen von Wasser- und Dampfmenge je ein Dosierventil in den Zufuhrleitungen angeordnet ist.Ease of use as well as high reliability and safety are achieved in that a valve is arranged in the water supply line and in the steam supply line, the valve adjusting elements of which can be actuated by a common linkage. Here, the linkage can have an adjustment device by means of which the opening ratio of the valves can be changed, so that the temperature gradient of the flow and the flow of the hot water can be optimally adapted to the consumer. It is preferably proposed that a metering valve is arranged in each of the feed lines for adjusting the amount of water and steam.

Zwei Ausführungsbeispiele der Erfindung sind in den Zeichnungen darstellt und werden im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine schematische Darstellung der Vorrichtung, einer ersten Ausführungsart,
  • Fig. 2 eine Seitenansicht der Vorrichtung mit einem Längsschnitt durch das Sicherheitsventil, und
  • Fig. 3 eine Seitenansicht der Vorrichtung mit oberem Gestänge zum gleichzeitigen Bedienen des Wasserabsperrventils und des Dampfabsperrventils.
  • Fig. 4 eine schematische Darstellung einer zweiten Ausführungart.
Two embodiments of the invention are shown in the drawings and are described in more detail below. Show it:
  • 1 is a schematic representation of the device, a first embodiment,
  • Fig. 2 is a side view of the device with a longitudinal section through the safety valve, and
  • Fig. 3 is a side view of the device with an upper linkage for simultaneously operating the water shut-off valve and the steam shut-off valve.
  • Fig. 4 is a schematic representation of a second embodiment.

Die Mischbatterie besteht eingangs aus der Zuführleitung für Wasser 1, dem Wasserabsperrventil 3, der Zuführungsleitung für Dampf 2 und dem Dampfabsperrventil 4. Die Absperrventile 3 sind über ein Gestänge 5 mit dem Bedienungshebel 6 so verbunden, daß beide Absperrventile 3 und 4 gleichsinnig betätigt werden, wobei die Absperrarmatur für Wasser 3 vorrangig geöffnet wird. Über die Verstelleinrichtung 7 am Gestänge 5 ist das Öffnungsverhältnis der beiden Absperrarmaturen 3 und 4 einstellbar und damit kann der Temperaturgradient des Vorlaufs und des Nachlaufs des Warmwassers in optimaler Weise an den Verbraucher angepaßt werden.The mixer tap initially consists of the supply line for water 1, the water shut-off valve 3, the supply line for steam 2 and the steam shut-off valve 4. The shut-off valves 3 are connected via a linkage 5 with the operating lever 6 so that both shut-off valves 3 and 4 are actuated in the same direction, the shut-off valve for water 3 being opened primarily. The opening ratio of the two shut-off valves 3 and 4 can be adjusted via the adjusting device 7 on the linkage 5, and the temperature gradient of the flow and flow of the hot water can thus be optimally adapted to the consumer.

Die Einstellung der gewünschten Wassermenge erfolgt über das Dosierventil 8 in der Wasserzuführleitung 1, die Einstellung der gewünschten Wassertemperatur über das Dosierventil 9 in der Dampfzuführungsleitung 2.The desired amount of water is set via the metering valve 8 in the water supply line 1, and the desired water temperature is set via the metering valve 9 in the steam supply line 2.

Der Steuermechanismus besteht aus dem zylindrischen Gehäuse 10 mit dem quer zur Längsrichtung des Zylinderbodens 11 im Wasserraum 12 und dem auch quer angeordneten Zwischenboden 13 im Dampfraum 14 sowie aus der Bohrung 15 (Drossel) im Zwischenboden 11 für die Wasserzuführung 20, de Steuerkörper 16 im Ventilsitz des Bodens 11, dem Dampfregelventil 18 im Zwischenboden 13 sowie der Rückstelleinrichtung 17. Das kegelstumpfförmige Verstellglied 18 ist über eine Stange 18a mit einem temperaturbeständigen (Kunststoff-) Faltenbelag 17a der Rückstelleinrichtung 17 verbunden. Das Innere des Faltenbelags 17a ist Kaltwasser und dessen Druck ausgesetzt. Die Teile 10, 11, 13, 16, 17a, 18, 18a liegen zueinander koaxial. Der sich beim Betätigen des Bedienungshebels 6 durch das Öffnen des Wasserabsperrventils 3 im Wasserraum 12 unterhalb des Steuerkörpers 16 aufbauende Wasserdruck hebt den Steuerkörper 16 an und gibt damit den Weg des Wassers zum Mischrohr 19 frei. Zeitverzögert verschiebt der anstehende Wasserdruck über die Rückstelleinrichtung 17 den Ventilkegel des Dampfregelventils 18 und gibt damit die Dampfzufuhr zum Mischrohr 19 frei.The control mechanism consists of the cylindrical housing 10 with the transverse to the longitudinal direction of the cylinder base 11 in the water chamber 12 and the transversely arranged intermediate floor 13 in the steam chamber 14 and from the bore 15 (throttle) in the intermediate floor 11 for the water supply 20, de control body 16 in the valve seat of the floor 11, the steam control valve 18 in the intermediate floor 13 and the reset device 17. The truncated cone-shaped adjusting member 18 is connected via a rod 18a to a temperature-resistant (plastic) pleated covering 17a of the reset device 17. The inside of the pleated covering 17a is exposed to cold water and its pressure. The parts 10, 11, 13, 16, 17a, 18, 18a are coaxial with one another. The water pressure which builds up when the operating lever 6 is actuated by opening the water shut-off valve 3 in the water space 12 below the control body 16 raises the control body 16 and thus releases the path of the water to the mixing tube 19. With a time delay, the water pressure present shifts the valve cone of the steam control valve 18 via the resetting device 17 and thus gives the Steam supply to the mixing tube 19 free.

Im Mischrohr 19 ist ein statischer Mischer 20 eingebaut. An das Mischrohr schließt sich die Warmwasserleitung 21 mit dem Warmwasserventil 22 an. Bei geöffneten Absperrventilen 3 und 4 kann das Warmwasserventil 22 auch als Bedienungsventil benutzt werden, ohne daß die Funktionsfähigkeit der Sicherheitsmischbatterie beeinträchtigt wäre.A static mixer 20 is installed in the mixing tube 19. The hot water line 21 with the hot water valve 22 connects to the mixing tube. When the shut-off valves 3 and 4 are open, the hot water valve 22 can also be used as an operating valve without the functionality of the safety mixer tap being impaired.

Mit der Sicherheitsbatterie wird ausgeschlossen, daß bei Abfall des Wasserdrucks Dampf aus der Warmwasserleitung 21 ausströmt und zur Verbrennung von Bedienungspersonal oder zur Schädigung temperaturempfindlicher Stoffe oder Einrichtungen führt. Außerdem wird eine schlechte Ausnutzung der hochwertigen Energie Dampf ausgeschlossen.With the safety battery it is excluded that when the water pressure drops, steam flows out of the hot water line 21 and leads to the combustion of operating personnel or damage to temperature-sensitive substances or devices. In addition, poor exploitation of the high-quality energy of steam is excluded.

Durch die Ausbildung des Steuerventils für Wasser in der bevorzugten Ausführung als Schwimmkörper 16 dient dieses Ventil gleichzeitig als Rückflußverhinderer, so daß bei Druckabfall des Wassers kein Dampf in die Zuführungsleitung für Wasser 1 strömen kann. Ein Rückströmen von Wasser in die Dampfzuführungsleitung 2 bei Abfallen des Dampfdrucks wird durch einen eingebauten Rückflußverhinderer 23, in der bevorzugten Ausführung durch ein Rückschlagventil verhindert.Due to the design of the control valve for water in the preferred embodiment as a float 16, this valve also serves as a backflow preventer, so that no steam can flow into the supply line for water 1 when the water drops in pressure. A backflow of water into the steam supply line 2 when the steam pressure drops is prevented by a built-in backflow preventer 23, in the preferred embodiment by a check valve.

Während in dem in den Fig. 1 bis 3 gezeigten Ausführungsbeispiel das Ventilstellglied bzw. der Steuerkörper 16 von einer freien Kugel gebildet wird, kann der Steuerkörper auch in Schließrichtung federbelastet sein, um die Vorrichtung in einer nicht vertikalen, insbesondere waagerechten Stellung, insbesondere waagerechten Stellung einbauen zu können.1 to 3, the valve actuator or the control body 16 is formed by a free ball, the control body can also be spring-loaded in the closing direction in order to keep the device in a non-vertical, in particular horizontal position, in particular horizontal position to be able to install.

Die Ausführung 2 unterscheidet sich von Ausführung 1 wie folgt:
- die Bohrung 15, ausgeführt als Festdrossel und der Schwimmkörper 16 entfallen und werden durch den geführten und federbelasteten Schwimmkörper (25) ersetzt,
- zur Verhinderung des Eindringens von Dampf in die Wasserzufuhrleitung (1), bei Beschädigung des Faltenbalges (17a), ist der Wasserzufuhrleitung (1) zwischen Gehäuse (10) und der Wasserzufuhrleitung ( 1) ein Rückschlagventil (24) angeordnet. Die Funktion des Dampfregelventiles (19) wird durch die Beschädigung des Faltenbalges nicht beeinträchtigt. Version 2 differs from version 1 as follows:
- The bore 15, designed as a fixed throttle and the floating body 16 are eliminated and are replaced by the guided and spring-loaded floating body (25),
- To prevent the penetration of steam into the water supply line (1), if the bellows (17a) is damaged, the water supply line (1) between the housing (10) and the water supply line (1) a check valve (24) is arranged. The function of the steam control valve (19) is not affected by damage to the bellows.
