Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf ein Mischventil zum Einstellen von verschiedenen Mischungen von Warmund Kaltwasser und mit selbsttätiger Regelung der Mischwassertemperatur durch Verwendung von in ihrer Längsrichtung dehn- und zusammenziehbaren Hohlrippenrohren bzw. Federbälgen.The invention relates to a mixing valve for setting different mixtures of warm and Cold water and with automatic control of the mixed water temperature by using in their longitudinal direction expandable and contractible hollow finned tubes or bellows.
Bei den bekannten, derartigen Mischventilen ist man gezwungen, das Hohlrippenrohr in großen Baulängen verbunden mit einer großen Wellenzahl auszuführen, um Überbeanspruchungen durch zu starke Streckungen zu vermeiden. Dadurch ergibt sich eine unerwünscht große Baulänge des Mischventils. Die Baulänge wird so groß, daß man gezwungen ist, das Ventil vor die Wand zu installieren, weil die Baunormen bestimmte Mauerwerkstärken vorschreiben, so daß das von der modernen sanitären Technik erwünschte Verlegen unter Putz nicht möglich ist.In the case of the known mixing valves of this type, the hollow finned tube is forced to have great overall lengths connected with a large wave number to avoid overstressing caused by excessive Avoid stretching. This results in an undesirably long overall length of the mixing valve. the The overall length is so great that one is forced to install the valve in front of the wall because of the building standards prescribe certain masonry thicknesses, so that what is desired by modern sanitary technology Laying under plaster is not possible.
Wenn man die bewährten Mindestlängen der Hohlrippenrohre kürzt, um das sperrige Aussehen des Gehäuses zu vermeiden und es innerhalb der Mauerstärke unterbringen zu können, so wird die Lebensdauer des Mischventils sehr beschränkt. Außerdem leidet die Temperaturgenauigkeit. Man kann zwar das Ventil unter Beibehaltung der vorgeschriebenen Baulänge breitseitig unter Putz verlegen. Bei dieser Einbauart sind jedoch zusätzliche Bauelemente notwendig, z. B. Kegelräder des Übertragungsgliedes oder flexible Wellen, die zu Ungenauigkeiten in der Temperatureinstellung führen.If you shorten the tried and tested minimum lengths of the hollow finned tubes to reduce the bulky appearance of the housing to avoid and to be able to accommodate it within the wall thickness, so the service life of the mixing valve is very limited. In addition, the temperature accuracy suffers. You can Lay the valve under plaster on the broad side while maintaining the prescribed length. At this Installation type, however, additional components are necessary, z. B. bevel gears of the transmission link or flexible shafts that lead to inaccuracies in the temperature setting.
Mit der Erfindung läßt sich die sonst notwendige große Baulänge vermeiden, indem mehrere Federbälge konzentrisch ineinander angeordnet werden, die sich in ihrer Länge im wesentlichen überdecken und gegenseitig abstützen, so daß ihre Hübe sich addieren, wobei ihr Gesamthub durch die beiden Endstellungen des Verschluß Stückes begrenzt ist, das die beiden Einlässesteuert, diebeidenFederbälgeaber innerhalb dieses Hubes frei ausdehnbar und zusammenziehbar sind.With the invention, the otherwise necessary large overall length can be avoided by arranging several spring bellows concentrically one inside the other, which essentially overlap in length and support each other so that their strokes add up, their total stroke being limited by the two end positions of the closure piece is that controls the two inlets, but the two bellows are freely expandable and contractible within this stroke.
Auf diese Weise ist die notwendige Länge des Federbalges oder Hohlrippenrohres so aufgeteilt, daß bei gleichem entsprechendem Hub die gleiche Ausdehnungslänge erreicht wird.In this way, the necessary length of the bellows or hollow rib tube is divided so that the same expansion length is achieved with the same corresponding stroke.
Man erhält dadurch ein Mischwasserventil, welches in der Baulänge erheblich reduziert ist, so daß man es ohne Schwierigkeiten unter Putz verlegen kann. An dem Reaktionsvermögen des Ventils ändert sich gegenüber der längeren Bauweise nichts. Das Ventil spricht in gleicher Weise bei Temperaturänderungen empfindlich an.This gives a mixed water valve, which is considerably reduced in length, so that one it can be laid under plaster without difficulty. The responsiveness of the valve changes nothing compared to the longer construction. The valve speaks in the same way when the temperature changes sensitive to.
Man kann mehr als zwei ineinandergeschachtelte Teilstücke der Hohlrippenrohre verwenden, und zwar mit der gleichen Auswirkung auf das gesamte notwendige Ausdehnungsmaß. Es ergeben sich dabei sehr geringe Bautiefen des Mischwasserventils bzw. -reglers.You can use more than two nested sections of the hollow finned tubes, namely with the same effect on the total necessary expansion. It turns out very much low installation depths of the mixed water valve or regulator.

In der Zeichnung sind zwei AusführungsbeispieleIn the drawing are two exemplary embodiments
ao (Fig. 1 und 2) der Erfindung dargestellt.ao (Fig. 1 and 2) of the invention.
Das Mischventil hat ein Gehäuse 1, bei dem ein Zulauf 2 z. B. für Heißwasser und ein Zulaufstutzen 3 für Kaltwasser vorgesehen ist. Die beiden Zuleitungen 4 und 5 führen zu einer Kammer 6, in der die Mischung zwischen Heiß- und Kaltwasser stattfindet, je nachdem welche Stellung das Doppelventil 7 mit den Verschlußkegeln 8 und 9 einnimmt. Dieses Ventil steht unter der Wirkung einer Feder 10. Von der Kammer 6 führt eine um die Zuleitung 5 herumführende Leitung 11 zu dem thermostatischen Element 12, das über die Scheibe 13 mit einer Ventilstange 14 in Wirkungsverbindung steht, die mittels des Handgriffes 15 betätigt werden kann. An der Stange 14 befindet sich das Abschlußventil 16. Das das thermostatische Element umspülende Wasser gelangt über den Raum 17 durch die Kammer 18 in den Schraubteil 19 und den querlaufenden Kanal 20 zu dem Raum 21 und dort zu dem Auslaßkanal 22 zwischen den Auslässen 23 bzw. 24. Die Auslässe 23 bzw. 24 können mittels des Umstellhahnes 25 und des halbzylindrischen Schiebers 26 wahlweise geschlossen oder geöffnet werden. Das dargestellte Mischventil zeigt außerdem noch die Ausgestaltung, daß mit dem Hebel 15, mit dem die Temperatur der durchströmenden Flüssigkeit durch Verstellung der Scheibe 13 einstellbar ist, das Abschlußventil 16 betätigt werden kann. Insoweit bietet das Ventil keine Besonderheiten. The mixing valve has a housing 1, in which an inlet 2 z. B. is provided for hot water and an inlet connection 3 for cold water. The two feed lines 4 and 5 lead to a chamber 6 in which the mixture of hot and cold water takes place, depending on which position the double valve 7 with the closure cones 8 and 9 assumes. This valve is under the action of a spring 10. A line 11 , which runs around the supply line 5 , leads from the chamber 6 to the thermostatic element 12, which is operatively connected via the disk 13 to a valve rod 14 which can be actuated by means of the handle 15 . The shut-off valve 16 is located on the rod 14. The water flowing around the thermostatic element passes via the space 17 through the chamber 18 into the screw part 19 and the transverse channel 20 to the space 21 and there to the outlet channel 22 between the outlets 23 and 24. The outlets 23 and 24 can optionally be closed or opened by means of the reversing valve 25 and the semi-cylindrical slide 26. The mixing valve shown also shows the embodiment that with the lever 15, with which the temperature of the flowing liquid can be adjusted by adjusting the disk 13 , the shut-off valve 16 can be actuated. In this respect, the valve offers no special features.
Das thermostatische Element 12 besteht aus einer Anordnung von Hohlrippenrohren 27 und 28, die ineinandergeschachtelt sind. Hierbei stützt sich das Hohlrippenrohr 28 mittels des Fußes 29 auf den Boden 30 einer Büchse 31 ab, die Bestandteil des Hohlrippenrohrelementes 27 ist. Zwischen dem TeilThe thermostatic element 12 consists of an arrangement of hollow finned tubes 27 and 28 which are nested one inside the other. Here, the hollow-finned tube 28 is supported by means of the foot 29 on the bottom 30 of a bushing 31 , which is part of the hollow-finned tube element 27 . Between the part
