Description

Thermostatisch gesteuertes Regelventil, insbesondere Dampfwasserableiter Zur Erzielung einer einwandfreien Funktion von thermostatisch gesteuerten Regelventilen ist es erforderlich, die mit dem durchfließenden Medium ankommenden Schmutzteilchen vom Thermostat und vom Abschlußorgan fernzuhalten. Zu diesem Zweck wird meist ein Sieb verwendet, das entweder in einem getrennten Gehäuse vor dem Regelventil in die Rohrleitung eingebaut wird oder mit im Gehäuse des Regelventils untergebracht ist. Während die Anordnung eines Siebes in einem besonderen Gehäuse einen sehr großen baulichen Aufwand erfordert, ist bei den in das Gehäuse des Regelventils mit einbezogenen Sieben, die bisher als flache oder zylinderförmige Siebe bekannt sind, die wirksame Sieboberfläche meist sehr klein und damit der Strömungswiderstand groß.Thermostatically controlled regulating valve, especially steam water drain To achieve perfect functioning of thermostatically controlled control valves it is necessary to remove the dirt particles arriving with the flowing medium keep away from the thermostat and the closing device. This is usually done using a Sieve used, which is either in a separate housing in front of the control valve the pipeline is installed or housed in the housing of the control valve is. Whereas the arrangement of a sieve in a special housing is a very large one Requires structural effort, is included in the housing of the control valve Sieves, previously known as flat or cylindrical sieves, are the most effective The sieve surface is usually very small and therefore the flow resistance is large.

Aufgabe der Erfindung ist es, die wirksame Siebfläche der in das Gehäuse des Regelventils eingebauten Siebe wesentlich zu vergrößern und dadurch den Strömungswiderstand zu verringern, ohne daß das Gehäuse selbst größer gebaut werden muß.The object of the invention is to reduce the effective screen surface in the housing of the control valve built-in sieves and thereby the flow resistance to reduce without the housing itself must be built larger.

Die Erfindung geht aus von einem thermostatisch gesteuerten Regelventil, insbesondere einem Dampfwasserableiter, mit einem im Gehäuse des Regelventils untergebrachten, in Durchflußrichtung vor dem Thermostat angeordneten Sieb und besteht darin, daß das Sieb glockenförmig um den Thermostat herum angeordnet ist, wobei die Maschenweite des Siebes sich zu dessen geschlossenem Ende hin, also nach oben hin, vergrößert. Das Sieb wird vorteilhaft durch einen bügelförmigen, den Thermostat umgebenden Stützkörper gehalten.The invention is based on a thermostatically controlled control valve, in particular a steam trap, with one housed in the housing of the control valve, arranged in the flow direction upstream of the thermostat sieve and consists in that the sieve is arranged in a bell shape around the thermostat, with the mesh size of the sieve is enlarged towards its closed end, i.e. towards the top. The sieve is advantageously provided by a bow-shaped support body surrounding the thermostat held.

Die erfindungsgemäße Ausbildung des im Gehäuse des Regelventils untergebrachten Siebes hat den Vorteil, daß der Durchflußwiderstand des Regelventils weit unter dem der bekannten Regelventile liegt und daß das durchfließende Medium gezwungen wird, dicht am Thermostat vorbeizuströmen, wodurch dessen Reaktionszeit bei Temperaturänderungen beträchtlich verkürzt wird. Durch die nach oben hin wachsende Maschenweite des Siebes wird das durchströmende Medium so beeinflußt, daß es die gesamte Oberfläche des Siebes zum Durchströmen ausnutzt und von allen Seiten den Thermostat umströmt. Die kontinuierliche Vergrößerung der Maschenweite vom Führungsring bis zum oberen, geschlossenen Ende des glockenförmigen Siebes läßt sich durch besondere Maßnahmen beim Tiefziehen des Siebes erreichen.The inventive design of the housed in the housing of the control valve Sieves has the advantage that the flow resistance of the control valve is far below that of the known control valves and that the flowing medium is forced will flow close to the thermostat, reducing its response time to temperature changes is shortened considerably. Due to the increasing mesh size of the sieve the flowing medium is influenced in such a way that it covers the entire surface of the Utilizes sieves to flow through and flows around the thermostat from all sides. the continuous enlargement of the mesh size from the guide ring to the upper, closed one The end of the bell-shaped screen can be removed by special measures during deep drawing of the sieve.

In der Zeichnung ist ein thermostatisch gesteuertes Regelventil mit einem darin angeordneten erfindungsgemäßen Sieb dargestellt. Das Gehäuse 1 des Regelventils ist mit einem Einlaßkana12 und einem Auslaßkana13 versehen und durch einen Deckel 4 verschlossen. Im Gehäuse 1 ist eine Baueinheit angeordnet, welche im wesentlichen aus einer Halterung 5, einem Abschlußorgan 6, einem Thermostat 7 und einem glockenförmigen Sieb 8 besteht. Das Sieb 8 wird durch einen bügelförmigen Stützkörper 9 gehalten, welcher mit der Halterung 5 fest verbunden ist. An seinem freien Ende ist das Sieb 8 mit einem Führungsring 10 verbunden, der eine dichte Verbindung von Sieb 8 und Halterung 5 gewährleistet. Die Maschen des Siebes 8 werden mit wachsender Entfernung vom Führungsring 10, also nach dem oberen, geschlossenen Ende des Siebes 8 hin, weiter.The drawing shows a thermostatically controlled regulating valve with a sieve according to the invention arranged therein. The housing 1 of the control valve is provided with an inlet channel 12 and an outlet channel 13 and is closed by a cover 4. A structural unit is arranged in the housing 1 which essentially consists of a holder 5, a closing element 6, a thermostat 7 and a bell-shaped sieve 8. The sieve 8 is held by a bow-shaped support body 9 which is firmly connected to the holder 5. At its free end, the sieve 8 is connected to a guide ring 10 , which ensures a tight connection between the sieve 8 and the holder 5. The meshes of the sieve 8 become wider with increasing distance from the guide ring 10, that is to say towards the upper, closed end of the sieve 8.
