"Sperrventil mit automatischer entlüftung""Shut-off valve with automatic venting"
Sperrventile werden in Warmwasser-Pumpenheizungsanlagen verwendet und üblicherweise in Fließrichtung direkt hinter der Heizungspumpe eingebaut. Sie sollen verhindern, daß beim Abstellen der Pumpe aufgrund des Heizwasser-Temperaturunterschiedes in der Vor- und Rücklaufleitung eine Eigenzirkulation des Heizwassers eintritt.Shut-off valves are used in hot water pump heating systems and are usually installed directly behind the heating pump in the direction of flow. They are designed to prevent the heating water from circulating when the pump is switched off due to the difference in heating water temperature in the flow and return lines.
Bei längerer Stillstandszeit (z. B. im Sommer) und abgestellter Pumpe kann sich Luft unter dem geschlossenen Sperrventil sammeln. Diese Luftblase kann so groß werden, diß dt/ Pumpeninnenraum mit Luft gefüllt ist. Beim Einschalten der Pumpe würö? sich dann das Förderrad in der Luftblase drehen und kein Wasser ansaugen. Die Heizungsanlage wäre damit nicht funktionsfähig, und die Heizungspumpe könnte zerstört werden.If the pump is not in use for a long time (e.g. in summer) and is turned off, air can collect under the closed shut-off valve. This air bubble can become so large that the inside of the pump is filled with air. When the pump is switched on, the impeller would then rotate in the air bubble and not take in any water. The heating system would then not function and the heating pump could be destroyed.
Um diesen Nachteil zu beseitigen, wird erfindungsgemäß vorgeschlagen, den Teller des Sperrventiles durch einen Bypaß zu umgehen. Der Bypaßkanal enthält einen Ventilsitz, der durch einen Absperrkörper bei einer Rückströmung verschlossen wird.In order to eliminate this disadvantage, the invention proposes to bypass the plate of the shut-off valve using a bypass. The bypass channel contains a valve seat which is closed by a shut-off body in the event of backflow.
Das Sperrventil besteht aus dem Gehäuse 1 mit dem Eintrittsstutzen 2 und dem Austrittsstutzen 3. In dem Gehäuse 1 ist der Ventilsitz 1 angeordnet, der mit dem Teller 5 zusammenarbeitet. Der Teller 5 ist einseitig mit dem Zapfen 6 in der Tellerführung 7 und anderseitig mit den Füßen 8 in der Bohrung 9 gelagert. Die Feder 10 drückt den Teller 5 in Schließstellung. Der Bypaß wird durch die Bohrungen 11 und 12 gebildet. Die Bohrung 12 ist abgesetzt, wobei der Absatz 13 den Ventilsitz für den Verschlußkörper bildet. Der Öffnungsweg des Verschlußkörpers 11 wird durch die dicht in das Cehäuse 1 eingepetzte Schraube 15 begrenzt. Bei der Bildung einer Luftblase unter dem geschlossenen Teller 5 wird der Verschlußkörper 14 von seinem Sitz abgehoben, und die Luft kann durch den Bypafikanal entweichen The shut-off valve consists of the housing 1 with the inlet connection 2 and the outlet connection 3. The valve seat 1 is arranged in the housing 1 and works together with the plate 5. The plate 5 is mounted on one side with the pin 6 in the plate guide 7 and on the other side with the feet 8 in the bore 9. The spring 10 presses the plate 5 into the closed position. The bypass is formed by the bores 11 and 12. The bore 12 is stepped, with the step 13 forming the valve seat for the closure body. The opening path of the closure body 11 is limited by the screw 15 which is tightly fitted into the housing 1. When an air bubble forms under the closed plate 5, the closure body 14 is lifted off its seat and the air can escape through the bypass channel.
