Abstract
Description
Die Erfindung betrifft einen sogenannten Heizkreisverteiler zum Anschluß an Flüssigkeitserhitzer, insbesondere Heizkessel, bestehend aus einem Gehäuse mit erhitzer- und heizkreisseitigen Vor- und Rücklaufanschlüssen, die im Gehäuse durch Kanäle miteinander in Verbindung stehen, die ihrerseits durch Anschlußbereiche für eine Heizkreispumpe und ein Beimischventil geführt sind.The invention relates to a so-called heating circuit distributor for Connection to a liquid heater, especially a boiler from a housing with heating and heating circuit side Flow and return connections in the housing through channels with each other are connected, which in turn through connection areas for a heating circuit pump and an admixing valve are.
Derartige Heizkreisverteiler sind hinlänglich bekannt und in
Benutzung, so daß es dazu an sich keines besonderen druckschriftlichen
Nachweises bedarf. Nur bspw. sei hierzu verwiesen
auf die DE-A-2734663, deren Gegenstand noch in Schalenbauweise
erstellt ist. Mittlerweile werden derartige Heizkreisverteiler
auch in Form von in sich einheitlichen Gußblöcken ausgeführt.
Bekannt und üblich ist auch, solchen Heizkreisverteilern unmittelbar
hinter den heizkreiseitigen Vor-und Rücklaufanschlüssen
in die von diesen abgehenden Vor-und Rücklaufstränge
eine beide Stränge verbindende Leitung mit Überströmventil
einzubinden. Die Anordnung derartiger Überströmventile in einer
Bypaßleitung zwischen den abgehenden Vor-und Rücklaufleitungen
ist außerdem an Heizkreisverteilern bekannt, die reine Leitungskonstruktionen
darstellen, wobei Leitungsbereiche teilweise
zusammengefaßt in Guß ausgeführt sein können. Zweck derartiger
mit Überströmventil ausgestatteter Überströmleitungen
ist es, bei Teillast oder bspw. auch bei Schließung aller in
einem Heizkreis vorhandener Heizkörperventile bei weiterlaufender
Pumpe noch für einen ausreichenden Mindestumlauf zu
sorgen, d.h., durch diese Maßnahme können störende, durch
unzulässigen Druckanstieg bedingte Fließgeräusche im Teil
lastbereich einer Zentralheizungsanlage vermieden werden. In
Anlagen mit vorgegebenen Mindestumlaufmengen bleibt auch, wie
erwähnt, bei geschlossen Thermostatventilen an den Heizkörpern
eine Mindestumlaufwassermenge erhalten.Such heating circuit distributors are well known and in use, so that no special printed evidence is required per se. For example, reference is made to DE-A-2734663, the subject of which is still in shell construction. In the meantime, such heating circuit distributors are also designed in the form of cast blocks which are in themselves uniform.
It is also known and customary to integrate such heating circuit distributors directly behind the heating circuit-side supply and return connections in the supply and return lines coming from them, a line connecting the two lines with overflow valve. The arrangement of such overflow valves in a bypass line between the outgoing supply and return lines is also known on heating circuit distributors which represent pure line constructions, whereby line areas can be partially cast in one piece. The purpose of such overflow lines equipped with an overflow valve is to ensure sufficient minimum circulation at partial load or, for example, even when all the radiator valves in a heating circuit are closed while the pump is still running, i.e. this measure can cause disturbing flow noises in the partial load range caused by impermissible pressure increases a central heating system can be avoided. In systems with specified minimum circulation quantities, as mentioned, a minimum quantity of circulating water is retained when the thermostatic valves on the radiators are closed.
Da die Anordnung eines Überströmventiles zwischen den heizkreisseitigen Leitungssträngen mit einem entsprechen Aufwand an Armaturen, Montagezeiten und Abdichtungserfordernissen verbunden ist, liegt der Erfindung die Aufgabe zugrunde, einen Heizkreisverteiler der eingangsgenannten Art, d.h. solchen in vorerwähnter Blockbauweise aus Guß dahingehend zu vereinfachen und zu verbessern, daß dieser Aufwand bei gewährleistet gleicher Funktion weitestgehend entbehrlich wird, und zwar verbunden mit der Maßgabe, die Überströmleitung eines solchen Heizkreisverteilers ohne großen Aufwand bei Nichtbedarf funktionslos zu machen.Since the arrangement of an overflow valve between the heating circuit side Line strings with a corresponding effort Valves, assembly times and sealing requirements connected is the object of the invention, a heating circuit distributor of the type mentioned at the outset, i.e. those in the aforementioned To simplify block construction of cast iron and to improve that this effort while ensuring the same Function is largely unnecessary, and connected with the proviso is the overflow line of such a heating circuit distributor without great effort when not in use do.
Diese Aufgabe ist mit einem Heizkreisverteiler der gattungsgemäßen Art nach der Erfindung dadurch gelöst, daß im Gehäuse zwischen den Kanälen druckseitig hinter dem Anschlußbereich der Heizkreispumpe ein beide Kanäle verbindende Überströmöffnung angeordnet und dieser ein Verschlußstopfen oder ein Differenzdruck-Überströmventil zugeordnet ist.This task is with a heating circuit distributor of the generic type Kind according to the invention solved in that in the housing between the ducts on the pressure side behind the connection area the heating circuit pump an overflow opening connecting both channels arranged and this a plug or a Differential pressure relief valve is assigned.
Bei dieser Lösung findet also unter entsprechenden Bedingungen
im Heizkreis die notwendige Mindestzirkulation im Heizkreisverteiler
selbst statt und alle bisher dafür notwendigen
äußeren Installationen und der damit verbundene Aufwand kommen
in Wegfall.
In konkreter Ausführungsform ist diese Lösung vorteilhaft derart
umgesetzt, daß am Gehäuse fluchtend zur Überströmöffnung
eine Anschlußöffnung für den Verschlußstopfen oder das Überströmventil
angeordnet ist und daß ferner im zum heizkreistigen
Vorlaufanschluß führenden Kanal der druckseitige Raum hinter
der Pumpe durch eine in Form einer Stufe ausgebildeten Wand
vom den Rücklauf führenden Kanal getrennt und in dieser Wand
die in Form eines Ventilsitzes ausgebildete Überströmöffnung
angeordnet ist.
Die Anschlußöffnung am Gehäuse ist dabei mit Innengewinde ausgestattet
und der Verschlußstopfen und das Differenzdruck-Überströmventil
sind mit entsprechenden, zum Innengewinde passenden
Außengewinden versehen.With this solution, the necessary minimum circulation in the heating circuit distributor itself takes place under appropriate conditions in the heating circuit and all the external installations previously required and the associated effort are eliminated.
In a concrete embodiment, this solution is advantageously implemented in such a way that a connection opening for the sealing plug or the overflow valve is arranged on the housing in alignment with the overflow opening and that, furthermore, in the duct leading to the heating flow connection, the pressure-side space behind the pump is formed by a wall in the form of a step from the return leading channel separated and in this wall the overflow opening designed in the form of a valve seat is arranged.
The connection opening on the housing is equipped with an internal thread and the sealing plug and the differential pressure overflow valve are provided with corresponding external threads that match the internal thread.
