Description
Die Erfindung betrifft einen Stoßdämpfer für Speiseleitungen von Dampferzeugern, insbesondere Röhrenschnellverdampfern, bei dem ein in der Speisedruckleitung angeordneter Dämpfungsraum ein durch entsprechende Beheizung eines Teiles des Speisemittels entstehendes Dampfpolster enthält. Erfindungsgemäß wird nun vorgeschlagen, den Dämpfungsraum durch ein von der Speiseleitung abzweigendes, blind endigendes Rohrstück zu bilden, das sich mit seinem freien Ende als Rohrschlange um eine Frisch- oder Anzapfdampfleitung legt. Ferner ist noch vorgesehen, das als Dämpfungsraum dienende Rohrstück von der Speiseleitung hinter einem Rückschlagventil abzuzweigen.The invention relates to a shock absorber for feed lines of steam generators, in particular Tube high-speed evaporators in which a Damping space created by appropriate heating of a part of the feed Includes steam pad. According to the invention it is now proposed that the damping space to form by a branching off from the feed line, blind-ended pipe piece, which is with its free end as Lies a pipe coil around a fresh or bleed steam line. It is also planned branch off the pipe section serving as a damping chamber from the feed line behind a non-return valve.
Auf diese Weise ergibt sich eine besonders einfache, mit wenigen Mitteln herzustellende Druckausgleichsvorrichtung für die Pumpenschlage der als Kolbenpumpe ausgebildeten Arbeitsmittelfördereinrichtung in der Speiseleitung. Die Vorrichtung zeichnet sich darüber hinaus noch durch geringen Raumbedarf aus, was besonders beim Einbau solcher Einrichtungen in Röhrenschnellverdampfern auf Straßen- oder Schienenfahrzeugen von ausschlaggebender Bedeutung sein kann. Die Verlegung des Beginnes der Abzweigleitung hinter ein Rückschlagventil in der Hauptleitung verhindert das Übertreten von Dampfblasen in die Arbeitsmittelfördereinrichtung und damit eine Störung in deren Betrieb.This results in a particularly simple one that can be produced with few resources Pressure compensation device for the pump stroke designed as a piston pump Work equipment conveyor in the feed line. The device stands out above it in addition, due to the small footprint, which is particularly important when installing such facilities in tube high-speed evaporators on road or rail vehicles of decisive Meaning can be. Laying the beginning of the branch line behind a check valve in the main line prevents vapor bubbles from entering the work medium conveying device and thus a disruption in their operation.
Es sind nun zwar besonders beheizte Stoßdämpfer für Speiseleitungen von Dampferzeugern bekannt, jedoch waren dabei diese Druckausgleicfrsvorrichtungen als windkesselartige Gefäße ausgebildet, in denen oder an die dann die Beheizungseinrichtung angebracht ist. Diese Vorrichtungen nahmen aber so viel Platz, der für andere wichtige Nebeneinrichtungen benötigt wurde, ein, daß die Vorsehung einer solchen Anordnung für Fahrzeuge nicht in Frage kommen konnte.There are now specially heated shock absorbers for feed lines of steam generators known, but these pressure compensation devices were in the form of air tanks Vessels formed in which or to which the heating device is then attached is. However, these devices took up so much space for other important ancillary equipment was needed, one that the provision of such an arrangement for vehicles could not come into question.
Die Zeichnung gibt ein Schaubild für ein Ausführungsbeispiel wieder. t-sThe drawing shows a diagram for an embodiment. t-s
In der Darstellung bedeuten a die zum Kessel d führende Speiseleitung, e eine in die Leitung α eingeschaltete Kolbenpumpe, / ein ebenfalls in der Leitung α sitzendes Rückschlagventil, b die hinter dem Ventil c beginnende Abzweigung aus der Förderleitung, die bei b' mit einem vom Kessel d •kommenden Frischdampfleitungsstrang c in Berührung steht und bei b" blind endigt.In the illustration, a denotes the feed line leading to the boiler d , e a piston pump connected to the line α , / a check valve also located in the line α , b the branch from the delivery line beginning behind the valve c, which begins at b ' with a Boiler d • Coming main steam pipe line c is in contact and ends blindly at b ".
Statt der Anordnung der Berührungsstelle ty der Abzweigung b an einer Frischdampfleitung kann auch eine solche an einer vom Anzapfdampf aus einer Zwischenstufe einer Antriebsmaschine durchrlossenen oder gegebenenfalls auch an einer Ab dampfleitung vorgesehen werden.Instead of arranging the contact point ty of the junction b on a live steam line, it can also be provided on a steam line through which the bleed steam from an intermediate stage of a drive machine flows or, if necessary, also on a steam line.
