Definitions

Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Vorregelung von Heizkörpern nach den Merkmalen der Oberbegriffe der Ansprüche 1 und 9.The invention relates to a method and a device for the precontrol of radiators according to the features of the preambles of claims 1 and 9.
Die vorliegende Erfindung gliedert sich in zwei Grundprinzipien der Vorregelung von Heizkörpern, die erfindungsgemäß nicht wie aus dem Stand der Technik bekannt im Ventileinsatz, sondern in der unmittelbar unter dem Heizkörper angeordneten Anschlussverschraubung, einem Hahnblock integriert sind. Dabei umfasst die Erfindung die zwei an sich bekannten Grundprinzipien der Vorregelung, die aber in die Anschlussverschraubungen (Hahnblöcke) integriert werden, nämlich erstens das Prinzip der Vorregelung / Konstanthaltung des am Ventil wirksamen Differenzdruckes (Differenzdruckregelung) und zweitens das Prinzip der Begrenzung des über das Ventil zulässigen Heizfluid- bzw. Wasserstromes auf einen einstellbaren Wert.The present invention is divided into two basic principles of pre-regulation of radiators, which according to the invention are not integrated in the valve insert as known from the prior art, but in the connection fitting arranged directly below the radiator, a faucet block. In this case, the invention comprises the two known basic principles of pre-regulation, but which are integrated in the Anschlußverschraubungen (valve blocks), namely, first, the principle of pre-regulation / constant maintenance of the valve effective differential pressure (differential pressure control) and, secondly, the principle of limiting the over the valve permissible Heizfluid- or water flow to an adjustable value.
Die vorbekannten Verfahren und Bauformen weisen aber entweder einen fixen Differenzdruck auf oder es gibt nur einen einstellbaren maximalen Heizfluid- bzw. Wasserstrom, unabhängig vom Differenzdruck. Die Patentschrift
Die Aufgabe der vorliegenden Erfindung besteht deshalb darin ein Verfahren und eine Vorrichtung vorzustellen, mit welchen die aus dem Stand der Technik bekannten Lehren verbessert werden können.However, the previously known methods and designs either have a fixed differential pressure or there is only one adjustable maximum Heizfluid- or water flow, regardless of the differential pressure. The patent
The object of the present invention is therefore to present a method and a device with which the teachings known from the prior art can be improved.
Nach dem Prinzip der Differenzdruckregelung wird dazu in den Verbindungssteg eines Hahnblockes eine Differenzdruckerfassung eingesetzt, z. B. in Form eines federbelasteten Kolbens, oder einer Membran. Beide wirken dann über eine mechanische Verbindung zu Elementen, die den Querschnitt des Wasserstromes variieren. Solcherart Elemente können z. B. Kolbenschieber oder Klappen sein. Je nach Höhe der Druckdifferenz wird damit ein im Weg des Wasserstromes am Vorlauf- und / oder Rücklaufanschluss des Hahnblockes befindlicher Regelquerschnitt verändert. Bei steigender Druckdifferenz wird der Querschnitt verengt, bei sinkendem Differenzdruck wird er erweitert. Eine Anpassung des Vorregel-Differenzdruckes erfolgt beispielsweise durch Variation der Vorspannung der auf den Kolben wirkenden Feder oder der der Membran.According to the principle of differential pressure control, a differential pressure detection is used in the connecting web of a tap block, z. B. in the form of a spring-loaded piston, or a membrane. Both then act via a mechanical connection to elements that vary the cross section of the water flow. Such elements can z. B. piston valve or flaps. Depending on the magnitude of the pressure difference, a regulating cross-section located in the path of the water flow at the flow and / or return connection of the faucet block is thus changed. As the pressure difference increases, the cross section becomes narrowed, with decreasing differential pressure it is extended. An adaptation of the precursor differential pressure is effected, for example, by varying the bias of the spring acting on the piston or of the membrane.
Symmetrisch aufgebaute Anordnungen sind hierbei von Vorteil, da sie unabhängig davon, welcher der Anschlüsse als Vorlauf, also der mit dem höheren Gesamtdruck und welcher als Rücklauf, also der mit dem niedrigeren Gesamtdruck im Fluid, gewählt wird, gleichermaßen funktionieren. Dies ist besonders wichtig bei der Eckausführung des Hahnblockes, bei der horizontal aus der Wand kommende Rohre mit den vertikalen Anschlüssen am Heizkörper verbunden werden müssen. Eine Festlegung der Anschlüsse bezüglich der Zuordnung Vorlauf und Rücklauf würde zwei Ausführungsformen erforderlich machen, analoges gilt für die Hahnblockausführung mit integriertem Ventil, bei der sich die Variantenzahl ebenfalls verdoppeln würde.Symmetrically constructed arrangements are advantageous in this context, since they function equally regardless of which of the connections is used as the flow, that is, the one with the higher total pressure and which as the return, that is, with the lower total pressure in the fluid. This is particularly important in the corner design of the faucet block, in which horizontally coming out of the wall pipes must be connected to the vertical connections on the radiator. A determination of the connections with respect to the assignment flow and return would require two embodiments, the same applies to the Hahnblockausführung with integrated valve, in which the number of variants would also double.
Zur Umsetzung des Prinzips der Begrenzung des Heizfluid- bzw. Wasserstromes wird für die Begrenzung des Wasserstromes auf einen maximal zulässigen Wert beispielsweise ein federbelasteter Regelkegel oder eine federbelastete Regelklappe als Regeleinheit in einer bei geöffnetem Ventil durchströmten Regelgeometrie angeordnet. Bei steigendem Wasserstrom wird die im Durchflussquerschnitt angeordnete Regeleinheit aus der Neutrallage ausgelenkt. Steigt der Durchfluss bis auf den eingestellten maximal zulässigen Wert an, ist die Regeleinheit soweit ausgelenkt, dass ein weiteres Ansteigen des Durchflusses verhindert wird. Mittels Variation der Vorspannung der Feder, Variation der Distanz zwischen Regeleinheit und Regelgeometrie oder Variation des Durchflusswiderstandes der Regeleinheit kann auch hier eine Anpassung des maximal zulässigen Durchflusses erfolgen.To implement the principle of limiting the Heizfluid- or water flow is for limiting the water flow to a maximum allowable value, for example, a spring-loaded control cone or a spring-loaded control valve arranged as a control unit in a flow-through with open valve control geometry. As the flow of water increases, the control unit arranged in the flow cross-section is deflected out of the neutral position. If the flow increases to the set maximum permissible value, the control unit is deflected so far that a further rise in the flow is prevented. By variation of the bias of the spring, variation of the distance between the control unit and the control geometry or variation of the flow resistance of the control unit can also be made an adjustment of the maximum allowable flow.
Auch für dieses Prinzip gilt, dass symmetrisch aufgebaute Anordnungen von Vorteil sind, da sie unabhängig von der Wahl, welcher der Anschlüsse als Vorlauf und welcher als Rücklauf gewählt wird, gleichermaßen funktionieren.
Vorteil der beiden erfindungsgemäß umgesetzten Grundprinzipien ist die universelle Anströmbarkeit. Die stetige Regelung des Differenzdruckes muss unabhängig davon, welcher der beiden Anschlüsse des Hahnblockes als Vor- und welcher als Rücklaufanschluss gewählt wird, gleichermaßen funktionieren. Hintergrund ist, dass die anzuschließenden Heizkörper und Anschlussverschraubungen (Hahnblöcke) im Markt bezüglich der Positionierung von Vor- und Rücklauf nicht einheitlich gestaltet sind. Nachfolgend soll die Erfindung anhand von Ausführungsbeispielen zu den verschiedenen Ausführungsformen näher erläutert werden.It is also true for this principle that symmetrically constructed arrangements are advantageous, since they function equally regardless of the choice of which of the connections is selected as the flow and which as the return.
The advantage of the two basic principles implemented according to the invention is the universal ability to be approached. The continuous regulation of the differential pressure must function equally regardless of which of the two ports of the valve block is selected as the forward port and which as the return port. The background to this is that the radiators and connection fittings (faucet blocks) to be connected are not uniform in the market with regard to the positioning of supply and return lines. The invention will be explained in more detail with reference to embodiments of the various embodiments.

An einer der Verbindungen 1.1, 1.2 zum Heiznetz ist in einer durchströmten Kartusche 30 ein Regeleinsatz 31 mit einem Doppelkegel 32 zwischen zwei Federn 33, 34 befestigt. Der Strömungsweg geht am linken Anschluss des Hahnblockes 1 von oben kommend links in die Kartusche 30, durch den Regelquerschnitt (Regelblende) 35 des Regeleinsatzes 31 hindurch und dann rechts aus der Kartusche 30 heraus nach unten. In der Ruheposition befindet sich der Doppelkegel 32 in der Mittelstellung, dort befindet sich auch die zweifach ausgeführte Regelblende 35, 35'. Die Wasserströmung ist in der Mittelstellung maximal frei gegeben. Ein steigender Wasserstrom bei Vorlauf rechts lenkt den Doppelkegel 32 nach rechts aus der Mittelstellung heraus, der Durchfluss um den Doppelkegel 32 herum wird begrenzt. Ist der Vorlauf links, erfolgt die Auslenkung entsprechend nach links, die Wirkung auf den zulässigen Wasserstrom ist gleich. Um die wirksame Durchflussbegrenzung einstellen zu können, ist eine Verstellung des Abstandes zwischen den beiden Regelblenden 35,35', z. B. durch ein Links-Rechts-Gewinde, vorgesehen. Bei einem Tausch der Vorlaufmit der Rücklaufseite laufen die beschriebenen Vorgänge in anderer Richtung ab.In the

Im Verbindungssteg 1.5 zwischen Vor- und Rücklauf V, R befindet sich eine fluiddichte Membran 40, die je nach Druckverhältnissen in beide Richtungen auslenkbar ist. An der Membran 40 ist eine bewegliche Schubstange 41 befestigt, die auf miteinander verbundene Doppelkegel 42 einer Regeleinrichtung 43 in einer der Fluidverbindungen 1.1,1.2 zum Heiznetz wirkt.
