Description

Regel- und Sperrorgan zur Verhinderung der Übertragung .von Rückstößen in Dampferzeugern, Überhitzern und Vorwärmern beliebiger Art. Die Erfindung bezieht sich auf ein Regel-und Sperrorgan zur Verhinderung der übertragung von Rückstößen in Dampferzeugern, Überhitzern und Vorwärmern beliebtger Axt. In dem Hauptpatent wird ein Regel- und Sperrorgan der vorliegenden. Art unter Schutz gestellt, das, besondere Kanäle besitzt, durch die das zu erwärmende und zu verdampfende Mittel derart geführt wird:, daß seine Strömung der Gewichtswirkung des frei. beweglich angeordneten Regel- oder Sperrorgans .entgegenwirkt. Gemäß vorliegender Erfindung soll eine Verbesserung dieser Einrichtung dadurch erbielt werden, daß neben .dem Regel- und Sperrorgan ständig offene Durchströmöffnungen für die zu verdampfende bzw. zu er- bzw. überhitzende Flüssigkeit vorgesehen werden. Diese sind so bemessen, daß sie als Drosselstellen wirken und hierdurch ein Rückströmen der Flüssigkeit bei auftretenden Druckstößen verhindern. Das Regelorgan selbst dient zum Durchlaß von infolge stärkerer Dampfentnahme .etwa erforderlich werdenden größeren Flüssigkeitsmengen.Control and locking device to prevent the transmission of recoil in steam generators, superheaters and preheaters of any kind. The invention relates relying on a regulating and blocking device to prevent the transmission of recoil Ax popular in steam generators, superheaters and preheaters. In the main patent becomes a regulating and blocking body of the present. Kind under protection that, has special channels through which the agent to be heated and evaporated is guided in such a way: that its flow is free from the weight effect of the. movable arranged regulating or blocking organ. counteracts. According to the present Invention, an improvement in this device is to be achieved in that besides .the regulating and blocking element constantly open flow openings for the to be evaporated or to be heated or superheated liquid are provided. These are dimensioned that they act as throttling points and thereby a backflow of the liquid prevent in the event of pressure surges. The regulating organ itself serves for the passage of larger amounts of liquid which may become necessary as a result of increased steam extraction.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar zeigt: Abb. i ein Fieldrohr mit einem am unteren Ende des Flüssigkeitszuführningsruubres angeordneten Regel- und Sperrorgan nach dem Hauptpatent, Abb.2 .einen Schnitt durch den Ventilsitz des Regel- und Sperrorgans, gemäß vorliegender Erfindung, Abb. 3 dien Ventilsitz nach Abb. a- in Grundriß.In the drawing, the invention is illustrated, for example, namely: Fig. i shows a field tube with a tube at the lower end of the liquid feed tube arranged regulating and blocking element according to the main patent, Fig.2. a section through the valve seat of the regulating and blocking element, according to the present invention, Fig. 3 the valve seat according to Fig. a- in plan.

In der Zeichnung ist a das nnntene Ende eines Fieldrohres, das durch ein Flüssigkeitszuführungsrohr b mit Flüssigkeit gespeist wird. Am unteren Ende dieses, Flüssigkeitszwfüb; rungsrohres ist ein Kopfstück c vorgesehen, in dem das Regel- und Sperrorgan gemäß der Erfindung angeordnet ist. Die nach unten strömende Flüssigkeit gelangt zunächst in eine Kammer d, strömt von dieser aus unter den, Ventilsitz i und hebt die als Rückschlagventil, wirkende Ventilkugel k an, worauf sie durch seitliche Kanäle nach unten in das Fieldrohr rx strömt.In the drawing, a is the inner end of a field tube that goes through a liquid supply pipe b is fed with liquid. At the bottom this, liquid zwfüb; approximately tube, a head piece c is provided in which the Control and locking member is arranged according to the invention. The one flowing down Liquid first enters a chamber d, from which it flows under the, Valve seat i and lifts the valve ball k, which acts as a check valve, whereupon it flows down through lateral channels into the field tube rx.

Wie aus Abb. a und 3 ersichtlich ist, ist der Ventilsitz i mit Einschnitten m versehen, die zusätzliche Durchströmöffnungen für die zu verdampfende Flüssigkeit bilden. n ist die den Ventilsitz enthaltende Platte. Die Durchströrnöffnungen können naturgemäß auch neben dem Ventilsitz oder sonstwo, beispielsweise als besondere Öffnungen, angeordnet werden.As can be seen from Fig. A and 3, the valve seat i is provided with incisions m which form additional throughflow openings for the liquid to be evaporated. n is the plate containing the valve seat. The flow-through openings can naturally also be arranged next to the valve seat or elsewhere, for example as special openings.
