Abstract

The invention relates to a valve for regulating the flow of hot water through a heating-system circuit and/or service-water circuit. Valves of this type comprise a housing (32), an inlet (33) and two outlets (34, 35). The incoming hot water that flows through the inlet can either be fed to a first outlet (34) or a second outlet, using a valve body (36). The first outlet feeds the hot water to the heating-system circuit and the second outlet feeds said water to the service-water circuit. A bypass valve (41) is integrated into the valve body of the inventive valve. The number of subassemblies necessary and the installation costs are thus reduced.

In such prior art combined systems, a standard 3-way valve is used to provide the water coming from the boiler to either the heating circuit or the process water circuit. In systems according to the prior art, a separate bypass valve is also required to avoid high pressure differences, which can damage the components of the system. The bypass adjustment must be connected to the system via its own connection lines. With regard to prior art • Reference is made to DE 198 37 012 Al, DE 35 37 063 Al and DE 295 00 325 Ul.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu - Grunde, ein neuartiges Ventil zur Regelung des Warmwässerstroms durch einen- Heizungskreislauf und/oder Brauchwasserkreislauf zu schaffen.Proceeding from this, the present invention addresses the problem of creating a novel valve for regulating the hot water flow through a heating circuit and / or process water circuit.
Dieses Problem wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Das erfindungsgemäße Ventil kombiniert die Funktion des nach dem Stand der Technik als separates Ventil ausgebildeten 3 -Wege- Ventils mit der Funktion des Bypaß-Ventils in einem einzigen Ventil. Hierdurch verringert sich die Anzahl der notwendigen Baugruppen sowie der Installationsaufwand. Dies ergibt eine Kostenredüktion. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und der Beschreibung. Nachfolgend wird ein bevorzugtes Ausfühningsbeispiel der Erfindung anhand der Zeichnung näher erläutert. In der Zeichnung zeigt:This problem is solved by a device with the features of claim 1. The valve according to the invention combines the function of the 3-way valve designed as a separate valve according to the prior art with the function of the bypass valve in a single valve. This reduces the number of modules required and the installation effort. This results in a cost reduction. Further advantageous embodiments of the invention result from the subclaims and the description. A preferred exemplary embodiment of the invention is explained in more detail below with reference to the drawing. The drawing shows:
Fig. 1 ein kombiniertes System aus Brauchwasserkreislauf und Heizungskreislauf nach dem Stand der Technik; Fig. 2 ein kombiniertes System aus Brauchwasserkreislauf und Heizungskreislauf unter Verwendung des erfindungsgemäßen Ventils; Fig. 3 das erfindungsgemäße Ventil im Querschnitt;Figure 1 shows a combined system of hot water circuit and heating circuit according to the prior art. Figure 2 shows a combined system of domestic water circuit and heating circuit using the valve according to the invention. Figure 3 shows the valve according to the invention in cross section.
Fig. 4 eine erste Arbeitsstellung des erfindungsgemäßen Ventils gemäß Fig. 3; Fig. 5 eine zweite Arbeitsstellung des erfindungsgemäßen Ventils gemäß Fig. 3; und Fig. 6 eine dritte Arbeitsstellung des erfindungsgemäßen Ventils gemäß Fig. 3.FIG. 4 shows a first working position of the valve according to the invention according to FIG. 3; FIG. 5 shows a second working position of the valve according to the invention according to FIG. 3; and FIG. 6 shows a third working position of the valve according to the invention according to FIG. 3.
Figur 1 zeigt ein kombiniertes System 10 aus Brauchwasserkreislauf und Heizungskreislauf nach dem Stand der Technik. Das von einem nicht-dargestellten Boiler erwärmte Wasser wird über eine Zuleitung 11 einem Standard-3- Wege- Ventil 12 zugeführt, an welchem zwei Ableitungen 13, 14 angreifen. Die erste Ableitung 13 führt das Warmwasser einem Heizungskreislauf 15 zu, während die zweite Ableitung 14 das Warmwasser einem Brauchwasserkreislauf 16 zuführt. Im Detail wird das Warmwasser einem in den Brauchwasserkreislauf 16 eingeschalteten Wärmeaustauscher 17 zugeführt. Der Wärmeaustauscher 17 erhitzt das Wasser des eigentlichen, vom Heizungskreislauf 15 strömungstechnisch getrennten Brauchwasserkreislaufs 16a. Mit anderen Worten wird das vom Standard-3-Wege- Ventil 12 der Ableitung 14 zugeführte Warmwasser über einen Eingang 18 dem Wärmeaustauscher 17 zugeführt und es verläßt den Wärmeaustauscher 17 über einen Ausgang 19. Hiervon getrennt ist der eigentliche Brauchwasserkreislauf 16a, dessen Kaltwasser dem Wärmeaustauscher über den Eingang 20 zugeführt wird und dessen Warmwasser dem Wärmeaustauscher 17 über einen Ausgang 21 verläßt. Über eine Pumpe 22 wird das Wasser wieder in Richtung auf den nicht-dargestellten Boiler zurückgefühlt.FIG. 1 shows a combined system 10 comprising a domestic water circuit and a heating circuit according to the prior art. The water heated by a boiler (not shown) is fed via a feed line 11 to a standard 3-way valve 12, to which two discharge lines 13, 14 act. The first discharge line 13 supplies the hot water to a heating circuit 15, while the second discharge line 14 supplies the hot water to a process water circuit 16. In detail, the hot water is supplied to a heat exchanger 17 switched into the process water circuit 16. The heat exchanger 17 heats the water of the actual service water circuit 16a, which is fluidically separated from the heating circuit 15. In other words, the hot water supplied from the standard 3-way valve 12 to the discharge line 14 is fed to the heat exchanger 17 via an inlet 18 and it leaves the heat exchanger 17 via an outlet 19. The actual process water circuit 16a, the cold water of which is the heat exchanger, is separated from this is fed via the input 20 and its hot water leaves the heat exchanger 17 via an output 21. The water is returned to the boiler (not shown) by a pump 22.
Bei dem in Figur 1 dargestellten System 10 nach dem Stand der Technik ist in Strömungsrichtung nach dem Standard-3- Wege- Ventil 12 in den Heizungskreislauf 15 ein separates Bypass-Ventil 23 über entsprechende Zu- und Ableitungen angeschlossen. Das Bypass-Ventil 23 ist erforderlich, um große Druckunterschiede zu vermeiden, die den Bauelementen des Systems 10 Schaden zufügen kömien. Wie bereits erwähnt, ist das Bypass-Ventil 23 bei den Systemen nach dem Stand der Technik als separates Ventil ausgestaltet. Demgegenüber zeigt Figur 2 ein System 30 unter Verwendung eines erfindungsgemäßen Ventils 31. Das erfindungsgemäße Ventil 31 kombiniert die Funktion des 3-Wege-Ventils und des Bypass-Ventils in einem einzigen Ventil. Hierdurch verringert sich die Anzahl der notwendigen Baugruppen und der Installationsaufwand. Dies sorgt insgesamt für eine Kostenersparnis. Um unnötige Wiederholungen zu vermeiden, sind in Figur 2 die Baugruppen, die ebenfalls bei dem System 10 der Figur 1 vorkommen, mit gleichen Bezugsziffern versehen. Es wird diesbezüglich auf die obigen Ausfüllrungen verwiesen.In the prior art system 10 shown in FIG. 1, a separate bypass valve 23 is connected in the flow direction after the standard 3-way valve 12 into the heating circuit 15 via corresponding supply and discharge lines. The bypass valve 23 is required to avoid large pressure differences, which could damage the components of the system 10. As already mentioned, the bypass valve 23 is designed as a separate valve in the systems according to the prior art. In contrast, FIG. 2 shows a system 30 using a valve 31 according to the invention. The valve 31 according to the invention combines the function of the 3-way valve and the bypass valve in a single valve. This reduces the number of modules required and the installation effort. Overall, this saves costs. In order to avoid unnecessary repetitions, the modules in FIG. 2, which also occur in the system 10 in FIG. 1, are provided with the same reference numbers. In this regard, reference is made to the fillings above.
Figur 3 zeigt das erfindungsgemäße Ventil 31 im Querschnitt: Einem Gehäuse 32 des Ventils 31 sind ein Einlaß 33 sowie zwei Auslässe 34, 35 zugeordnet. Am Einlaß 33 greift die Zuleitung 11 an, während am ersten Auslaß 34 die Ableitung 13 für den Heizungskreislauf 15 und am zweiten Auslaß 35 die Ableitung 14 für den Brauchwasserkreislauf 16 angreift. An dieser Stelle sei nochmals angemerkt, daß der eigentliche Brauchwasserkreislauf 16a strömungstechnisch hiervon getrennt ist. Mit dem Brauchwasserkreislauf 16 soll also das Warmwasser des Boilers dem Wärmeaustauscher 17 zur Erwärmung des eigentlichen, hiervon getrennten Brauchwasserkreislaufs 16a zugeführt werden.FIG. 3 shows the valve 31 according to the invention in cross section: an inlet 33 and two outlets 34, 35 are assigned to a housing 32 of the valve 31. At the inlet 33, the supply line 11 engages, while at the first outlet 34, the discharge line 13 for the heating circuit 15 and at the second outlet 35, the discharge line 14 for the hot water circuit 16 acts. At this point it should be noted again that the actual process water circuit 16a is separated from this in terms of flow. With the hot water circuit 16, the hot water of the boiler is to be supplied to the heat exchanger 17 for heating the actual, separate hot water circuit 16a.
Um das über die Zuleitung 11 zugeführte, vom nicht-dargestellten Boiler erhitzte Warmwasser entweder dem Heizungskreislauf 15 oder dem Brauchwasserkreislauf 16 zuzuführen, ist im Ventil 31 ein Ventilkörper 36 angeordnet, der mit einer Ventilstange 37 verbunden ist, die von einem Antrieb 38 zwischen den beiden Arbeitsstellungen des Ventilkörpers 36 hin- und herbewegt werden kann. Bei der in Figur 3 gezeigten Darstellung des erfindungsgemäßen Ventils 31 liegt der Ventilkörper 36 auf einem unteren Ventilsitz 39 auf, wobei in dieser Arbeitsstellung das Wäπnwasser über die Ableitung 13 dem Heizungskreislauf 15 zugeführt wird. Liegt hingegen der Ventilkörper 36 auf dem oberen Ventilsitz 40 auf, so wird das Warmwasser über die Ableitung 14 dem Brauchwasserkreislauf 16 zugefülirt.In order to supply the hot water supplied via the supply line 11 from the boiler (not shown) to either the heating circuit 15 or the hot water circuit 16, a valve body 36 is arranged in the valve 31, which is connected to a valve rod 37 which is connected by a drive 38 between the two Working positions of the valve body 36 can be moved back and forth. In the illustration of the valve 31 according to the invention shown in FIG. 3, the valve body 36 rests on a lower valve seat 39, the heating water being supplied to the heating circuit 15 via the drain 13 in this working position. If, on the other hand, the valve body 36 rests on the upper valve seat 40, the hot water is fed to the process water circuit 16 via the drain 14.
Erfindungsgemäß ist im Ventilkörper 36 ein Bypassventil 41 integriert. Das Bypass-Ventil 41 verfügt über ein Federelement 42. Das Federelement 42 hält das Bypass-Ventil 41 in Schließstellung. Unter Bezugnahme auf Figur 3 bedeutet dies, daß das Federelement 42 einen Ventilkörper 43 des Bypassventils 41 gegen einen entsprechenden Ventilsitz 44 desselben drückt. Nur dann, wenn der Druck im Heizungskreislauf 15 eine durch das Federelement 42 vorbestimmte Druckdifferenz überschreitet, öffnet das Bypass-Ventil 41 und nimmt die in Figur 3 gezeigte Position ein. Zum Druckausgleich wird dann über das Bypass-Ventil 41 Warmwasser dem Brauchwasserkreislauf 16 zugeführt. Figuren 4 bis 6 zeigen das erfindungsgemäße Ventil 31 in den drei möglichen Arbeitsstellungen. Die in Figur 6 gezeigte Darstellung entspricht der in Figur 3 gezeigten Arbeitsposition. In dieser Arbeitsposition leitet der Ventilkörper 36 das Warmwasser in den Heizungskreislauf 15, wobei gleichzeitig das Bypass-Ventil 41 infolge der herrschenden Druckbedingungen geöffnet ist und einen Teil des Warmwassers zum Druckausgleich in den Brauchwasserkreislauf 16 leitet. In der in Figur 5 gezeigten Arbeitsposition leitet der Ventilkörper 36 ebenfalls das Warmwasser in den Heizungskreislauf 15, wobei hingegen die durch das Federelement 42 des Bypass-Ventils 41 vorbestimmte Druckreferenz nicht überschritten ist und somit das Bypass-Ventil 41 geschlossen bleibt. In dieser Arbeitsposition wird demnach das gesamte Warmwasser dem Heizungskreislauf 15 zugeführt. In der in Figur 4 gezeigten Arbeitspositions des erfϊndungsgernäßen Ventils 31 leitet der Ventilkörper 36 das gesamte Wasser dem Braμchwasserkreislauf 16 zu. In dieser Arbeitsposition bleibt das Bypass-Ventil stets geschlossen. According to the invention, a bypass valve 41 is integrated in the valve body 36. The bypass valve 41 has a spring element 42. The spring element 42 holds the bypass valve 41 in the closed position. 3, this means that the spring element 42 presses a valve body 43 of the bypass valve 41 against a corresponding valve seat 44 thereof. Only when the pressure in the heating circuit 15 exceeds a pressure difference predetermined by the spring element 42 does the bypass valve 41 open and assume the position shown in FIG. 3. To equalize the pressure, hot water is then supplied to the process water circuit 16 via the bypass valve 41. FIGS. 4 to 6 show the valve 31 according to the invention in the three possible working positions. The representation shown in FIG. 6 corresponds to the working position shown in FIG. 3. In this working position, the valve body 36 conducts the hot water into the heating circuit 15, the bypass valve 41 being opened at the same time as a result of the prevailing pressure conditions and directing part of the hot water into the service water circuit 16 for pressure compensation. In the working position shown in FIG. 5, the valve body 36 also directs the hot water into the heating circuit 15, the pressure reference predetermined by the spring element 42 of the bypass valve 41 not being exceeded, and the bypass valve 41 thus remaining closed. In this working position, the entire hot water is accordingly supplied to the heating circuit 15. In the working position of the valve 31 according to the invention shown in FIG. 4, the valve body 36 directs all of the water to the hot water circuit 16. The bypass valve always remains closed in this working position.
