Description
Die Erfindung betrifft einen Strömungsregler gemäß dem Oberbegriff des Patentanspruchs 1, bekannt aus der EP-OS 106781.The invention relates to a flow regulator according to the preamble of Claim 1, known from EP-OS 106781.
Aufgabe der Erfindung ist es, den konstruktiven Aufbau, die Handhabung und Wartung solcher Strömungsregler zu vereinfachen und den allenfalls erforderlichen Austausch des Stellgliedes zu erleichtern.The object of the invention is the structural design, the handling and maintenance of such flow regulators simplify and the necessary exchange of the actuator to facilitate.
Erfindungsgemäß liegt die Lösung der Aufgabe in den Merkmalen des Patentanspruchs 1. According to the invention lies the solution to the problem in the features of the claim 1.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Patentansprüche.Advantageous further training the invention are the subject of the dependent claims.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in einer Zeichnungsfigur in einem Längsschnitt schematisch veranschaulicht. Der Erfindungsgegenstand beinhaltet eine zweiteilige Ausführung der vorzugsweise aus Kunststoff gefertigten Führungshülse, wobei eine Oberkappe aus verschleißfesterem Material, z. B. Metall, einen Ventilsitz darstellt, der im einen Fall auf die Führungshülse aufgeklipst und nach einem weiteren Beispiel aufgeschraubt sein kann. Diese der Vermeidung strömungsbedingter Erosionsschäden dienenden Oberkappen weisen ebenfalls radiale Zuflußöffnungen auf.An embodiment of the subject of the invention is in a drawing figure schematically illustrated in a longitudinal section. The subject of the invention includes a two-part version of the preferably made of plastic guide sleeve, one Upper cap made of more wear-resistant material, e.g. B. metal, represents a valve seat, which in one case on the Clip-on guide sleeve and according to another example can be screwed on. This avoidance top caps serving for flow-related erosion damage also have radial inflow openings.
Beim Strömungsregler gemäß der Figur besteht der Regelkolben 1 aus einem Rotationskörper mit einem über seine Länge variierenden Durchmesser, und zwar umfaßt dieser Körper einen zylindrischen Führungsbereich, mit dem er in einer Ringdichtung 2 geführt ist, einen Bereich verringerten Durchmessers, der in seiner Lage etwa den radialen Zuflußöffnungen 3 der Führungshülse 4 und Oberkappe 13 entspricht und einen sich stetig verjüngenden Bereich, der mit einem im Hohlraum 5 des Strömungsweges angeordneten Ventilsitz einen Ventilspalt 7 variierender Größe bildet.In the flow controller according to the figure, the control piston 1 consists of a rotating body with a diameter varying over its length, namely this body comprises a cylindrical guide area with which it is guided in an annular seal 2 , an area of reduced diameter, which in its position is approximately the same corresponds to radial inflow openings 3 of the guide sleeve 4 and the upper cap 13 and a continuously tapering region which forms a valve gap 7 of varying size with a valve seat arranged in the cavity 5 of the flow path.
Ein Verschlußdeckel 8, gegen den sich eine den Regelkolben 1 beeinflussende Feder 9 abstützt, hält die aus den genannten Bestandteilen bestehende, in einem Gehäuse 10 eingeschlossene Einheit in dem einen Teil des Strömungsweges bildenden Hohlraum 5 fest, wobei die Führungshülse 4 dichtend gegen das Widerlager 6 gedrückt wird.A sealing cover 8 , against which a spring 9 influencing the control piston 1 is supported, holds the unit consisting of the above-mentioned components enclosed in a housing 10 in the cavity 5 forming part of the flow path, the guide sleeve 4 sealingly against the abutment 6 is pressed.
Das Wasser, dessen Strömung zu regeln, nämlich konstant zu halten ist, gelangt über einen Zufluß 11 in den Hohlraum 5, tritt aus dem zwischen der Führungshülse 4 und dem Gehäuse 10 bzw. der Hohlraumwandung gebildeten Ringspalt über eine oder mehrere Öffnungen 3 in die Führungshülse 4 ein und wird - durch die jeweilige Größe des Ventilspaltes 7 geregelt - über die Abflußleitung 12 dem Heißwasserbereiter zugeführt, wobei die Strömung durch die hydraulische Gestaltung des sich in der Führungshülse 4 unter dem Einfluß des Strömungsdruckes und der Feder 9 bewegenden Regelkolbens 1 selbsttätig konstant gehalten wird.The water, the flow of which is to be regulated, namely to be kept constant, reaches the cavity 5 via an inflow 11 , exits the annular gap formed between the guide sleeve 4 and the housing 10 or the cavity wall via one or more openings 3 in the guide sleeve 4 and is - regulated by the respective size of the valve gap 7 - supplied to the hot water heater via the drain line 12 , the flow being kept constant by the hydraulic design of the control piston 1 moving in the guide sleeve 4 under the influence of the flow pressure and the spring 9 becomes.
Claims (3)
daß der Hohlraum (5) mittels des Verschlußdeckels (8), vorzugsweise durch Verschraubung, dichtend abgeschlossen ist,
daß die Führungshülse (4) mit der dem Verschlußdeckel (8) gegenüberliegenden Stirnseite an einem Widerlager (6) des Hohlraumes (5) abgestützt ist und
daß die Führungshülse (4) von einer Oberkappe (13) umfaßt ist, die aus verschleißfestem Material, z. B. Metall, hergestellt ist, wobei die Oberkappe (13) mit dem sich dort verjüngenden Bereich des Regelkolbens (1) einen Ventilsitz bildet.1. Flow controller for keeping the water supply of hot water heaters constant, with a spring-influenced control piston movable in a guide through which the fluid medium flows, the guide sleeve ( 4 ) having at least one radial inflow opening ( 3 ) with the control piston ( 1 ) and a spring abutment therein serving sealing cap ( 8 ) forms a unit which can be exchangeably inserted into a suitably dimensioned cavity ( 5 ) of the flow path, characterized in that
that the cavity ( 5 ) is sealed off by means of the sealing cover ( 8 ), preferably by screwing,
that the guide sleeve ( 4 ) is supported with the end face opposite the closure cover ( 8 ) on an abutment ( 6 ) of the cavity ( 5 ) and
that the guide sleeve ( 4 ) is surrounded by an upper cap ( 13 ) made of wear-resistant material, e.g. B. metal, is produced, wherein the upper cap ( 13 ) forms a valve seat with the region of the control piston ( 1 ) which tapers there.
