Description
In Form eines Absperrorgans mit düsenförmiger Durchtrittsöffnung ausgebildeter Dampfwasserableiter. Zwecks Vereinfachung und Verbilligung der Dampfwasserabscheidung aus Dampfleitungen sind Vorrichtungenbekannt geworden, die bei Vermeidung jeglicher beweglichen Organe lediglich durch einfache, feststehende Düsen das Dampfwasser ausströmen lassen, wobei die Düse im .Hahnküken eines Ventils angeordnet sein kann.In the form of a shut-off device with a nozzle-shaped passage opening Steam trap. For the purpose of simplifying and making steam water separation cheaper devices have become known from steam lines which, while avoiding any moving organs only through simple, fixed nozzles the steam water Let flow out, wherein the nozzle can be arranged in the .Hahnküken of a valve.
Bei geringem oder ganz ausbleibendem Dampfwasseranfall infolge hoher Leitungstemperatur oder genügend hoher Überhitzung des fortgeleiteten Dampfes tritt Dampf aus.If there is little or no steam water flow due to high Line temperature or sufficiently high overheating of the transported steam occurs Steam off.
Versuche haben nun zwar ergeben, daß infolge des sogenannten Siedeverzuges aus einer und derselben Düse und bei gleichem Druck in der Zeiteinheit mehr Kaltwasser als Heißwasser und nur sehr viel weniger Dampf austreten kann, so daß in diesem Umstande schon eine gewisse Selbstregelung liegt. Die Selbstregelung ist aber recht begrenzt und die Düsenbemessung bei wechselnden und meist vorher nicht genau .bestimmbaren Dampfwassermengen sehr unsicher und schwierig. Falsch bemessene Ableiter können dabei Dampfverluste verursachen. Vorübergehend anfallende größere Dampfwassermengen können nur durch Öffnen des Umlaufventils abgelassen wenden, was unzulänglich ist, da diese Arbeitsweise in der Regel Dampfverluste verursacht.Tests have now shown that as a result of the so-called boiling delay from one and the same nozzle and with the same pressure in the unit of time, more cold water than hot water and only a lot less steam can escape, so that in this Circumstances already a certain self-regulation lies. Self-regulation is right, however limited and the nozzle dimensioning with changing and mostly not exactly .determinable beforehand Steam water quantities very unsafe and difficult. Incorrectly sized arresters can cause steam losses. Temporary larger amounts of steam water can only be drained by opening the circulation valve, which is insufficient, as this mode of operation usually causes steam losses.
Um eine einfache Vorrichtung zu schaffen, welche diese Mängel beseitigt, wird gemäß dieser Erfindung die Ablaßdüse im Kegel eines Absperrventils untergebracht, deren Durchtrittsquerschnitt durch ein von außen einstellbares Nadelventil geregelt wenden kann. Hierbei kann das zum Schutze der Düse vorzuschaltende Sieb auf der Eintrittsseite des Ventilkegels an diesem befestigt sein.In order to create a simple device which overcomes these deficiencies, according to this invention, the discharge nozzle is accommodated in the cone of a shut-off valve, whose passage cross-section is regulated by an externally adjustable needle valve can turn. The screen to be connected upstream to protect the nozzle can be placed on the Be attached to the inlet side of the valve cone.
Die ganze Vorrichtung kennzeichnet sich in dieser Form als gewöhnliches Durchgangs-oder Eckventil, das auch in geschlossenem Zustande .den Düsenquerschnitt für den Ausfluß des Dampfwassers frei läßt.The whole device is characterized in this form as ordinary Transit or Angle valve that .den even when closed Leaves nozzle cross-section free for the outflow of steam water.
Das von außen einstellbare Nadelventil ist außen mit Skala und Zeiger ausgerüstet, so daß der jeweilige freie Düsenquerschnitt abgelesen werden kann. Die Spindel des Regelungsventils wird dLirch :die hohle Spindel des Absperrventils hindurchgeführt.The externally adjustable needle valve has a scale and pointer on the outside equipped so that the respective free nozzle cross-section can be read. The spindle of the control valve becomes dLirch: the hollow spindle of the shut-off valve passed through.
Mit Hilfe des Regelungsventils kann die Düse .auch ganz geschlossen werden, so daß bei gleichzeitig geschlossenem Umlaufventil der ganze Ableiter abgesperrt ist und die Vorschaltung reines besonderen Absperrorgans sich erübrigt.With the help of the control valve, the nozzle can also be completely closed so that when the circulation valve is closed at the same time, the entire trap is shut off and the upstream connection of a special shut-off device is unnecessary.
In Abh. i der Zeichnung ist A das Ventilgehäuse mit dem Ventilkegel B, der von außen durch die hohle Spindel C und das Handrad D bewegt werden kann. E ist die Ablaßdüse mit dein Schutzsie-b F. G ist das als Nadelventil ausgebildete Regelungsventil mit Handgriff und Zeiger H. Das Dampfwasser tritt in Richtung der Pfeile ein und aus.Depending on the drawing, A is the valve housing with the valve cone B, which can be moved from the outside through the hollow spindle C and the handwheel D. E is the outlet nozzle with your protective sieve-b F. G is designed as a needle valve Control valve with handle and pointer H. The steam water enters the direction of the Arrows in and out.
Abb. z zeigt eine andere Form des Nadelventils; dort ist die Düse unterteilt, so daß zwei Düsen E entstehen, die durch Längsnuten in der Spindel G gebildet sind.Fig. Z shows another form of needle valve; there is the nozzle divided, so that two nozzles E are formed by longitudinal grooves in the spindle G are formed.
