Description

Dampfwasserableiter mit vom Schwimmer bewegtem Abflußorgan. Die Erfindung betrifft einen mit Schwimmer versehenen Dampfwasserableiter (Kondenstopf) zur selbsttätigen Entfernung des sich abscheidenden Dampfwassers aus geschlossenen Behältern und Rohrleitungen, die mit Dampf oder Gasen gefüllt sind und unter gewissem Betriebsdruck stehen.Steam water trap with drainage element moved by the float. The invention relates to a steam drain (condensate trap) equipped with a float for automatic Removal of the steam water that separates out of closed containers and pipelines, which are filled with steam or gases and are under a certain operating pressure.

Derartige Vorrichtungen besitzen Auslaßventile oder -Schieber, die nach Maßgabe des zufließenden Wassers durch ,einen Schwimmer bewegt werden, und haben die Eigen-Schaft, daß die für diese Bewegung erforderliche und vom Schwimmer oder dessen Gewicht und Auftrieb aufzubringende Kraft in erster Linie von dem Produkt aus Ventil-oder Austrittsquerschnitt mal Ausflußdruck abhängt. Letzterer ist die Differenz der absoluten Drücke vor und hinter dem Abschlußorgan, also für gewöhnlich zwischen Betriebsdruck und äußerer Atmosphäre. Der Verwendungsbereicll derartiger Ableiter von gegebener Schwimmergröße ist demnach hinsichtlich des Betriebsdruckes mit Rücksicht auf das Arbeitsvermögen des Schwimmers engb.egrenzt, und man muß mit zunehmendem Betriebsdruck dazu übergehen, entweder den Schwimmer zu vergrößern oder den Austrittsquerschnitt des Abschlußorgans zu verkleinern, in welch letzterem Falle aber die Leistung oder Durchlaßmenge des Dampfwasserableiters abnimmt, weil die Ausflußgeschwindigkeit nicht proportional dem Ausflußdruck, sondern annähernd nur proportional der Quadratwurzel aus dem Ausflußdruck wächst.Such devices have exhaust valves or slides that moving a float according to the inflowing water, and have the own shaft that is required for this movement and used by the swimmer or its weight and buoyancy to be applied primarily by the product from the valve or outlet cross-section times the outlet pressure depends. The latter is the Difference in absolute pressures upstream and downstream of the closing organ, i.e. usually between the operating pressure and the external atmosphere. The range of use of such Trap of a given float size is therefore with regard to of Operating pressure is narrowly limited with regard to the work capacity of the swimmer, and as the operating pressure increases, you have to switch to either the float to enlarge or to reduce the exit cross-section of the closure organ, in in the latter case, however, the performance or flow rate of the steam trap decreases because the outflow velocity is not proportional to the outflow pressure, but rather approximately only proportionally to the square root of the outflow pressure increases.

Nach der Erfindung wird nun der Verwendungsbereich eines derartigen Ableiters von gegebenem Sch«rimmerausmaß und beliebiger bekannter Bauart vergrößert bzw. bei erhöhtem Betriebsdruck die sonst erforderliche Verkleinerung des Austrittsquerschnittes vermieden und die Leistung bzw. Durchlaßmenge konstant erhalten, indem durch Einbau eines mit Feder, Gewicht o. dgl. regulierbar belasteten selbsttätigen Auslaßventils in die Abflußleitung des Ableiters ein beliebig einstellbarer, unveränderlicher und so bemessener Staudruck erzeugt wird, daß der Ausflußdruck, d. h. die Differenz der absoluten Drücke vor und hinter dem durch den Schwimmer bewegten Abschlußorgan auch bei erhöhtem Betriebsdruck unverändert bleibt. In der schematischen Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht, und zwar ist a das vom Schwimmer bewegte Abschlußorgan und s das regulierbar belastete Stauventil. Um auch bei. aufsitzendem Stauventil ein Abfallen cles Staudruckes und damit ein Blockieren des vom Schwimmer bewegten Abflußorgans infolge der dann zu großen, dem Arbeitsvermögen des Schwimmers nicht mehr entsprechenden Druckdifferenz mit Sicherheit zu verhindern, kann eine kapillare Verbindung des Raumes zwischen Abschlußorgan a und Stauventil s mit dem unter Betriebsdruck stehenden Raum vor dem Abschlußorgan a, z. B. durch eine feine Bohrung k, hergestellt- werden. Für gewöhnlich werden die praktisch nicht zu vermeidenden Undichtigkeiten des vom Schwimmer bewegten Abschlußorgans a zur Verhinderung des Staudruckabfalles ausreichend sein. -According to the invention, the field of use of such a Arrester of a given size and of any known type enlarged or the otherwise necessary reduction of the outlet cross-section in the case of increased operating pressure avoided and the power or flow rate kept constant by installing an automatic outlet valve loaded with a spring, weight or the like in an adjustable manner into the discharge line of the arrester an arbitrarily adjustable, unchangeable one and back pressure is generated so that the outflow pressure, d. H. the difference the absolute pressures in front of and behind the closing organ moved by the float remains unchanged even with increased operating pressure. In the schematic drawing the subject matter of the invention is illustrated, for example, namely a is that the closing element moved by the float and s the adjustable pressure dam valve. To also at. seated back pressure valve a drop in the back pressure and thus a Blocking of the drainage organ moved by the swimmer as a result of the then too large, the Working capacity of the swimmer no longer corresponds to the pressure difference with certainty to prevent a capillary connection of the space between the closure organ a and back-up valve s with the space under operating pressure in front of the closing element a, z. B. by a fine bore k, are produced. Will usually be the practically unavoidable leaks in the closure member moved by the swimmer a be sufficient to prevent the back pressure drop. -
