Abstract (en)

A nozzle pipe (3) protrudes into the steam pipe and branches off from the cooling water supply unit (2) which has a regulator valve (4) regulating the water pressure (P2) in the nozzle (5)-pipe. Each nozzle has a tubular nozzle-pot (10) fixed in the nozzle pipe and crossing it. At least one water inlet (11) inside the nozzle-pipe is in the pot-casing. A spring-tensioned (12) nozzle pin (13) is positioned in the pot. A cap (15) is screwed onto the open end of the pot protruding from the pipe and has a spray hole (14) with which the end point (16) of the pin cooperates. The other end of the pin protruding from the pot base forms a piston surface exposed to steam pressure.(P1)

Abstract (de)

Der Einspritzkühler zur Temperaturregelung von überhitztem Dampf besitzt eine an einem Dampfrohr (1) festlegbare Kühlwasser-Zuführarmatur (2) und ein davon abgehendes und in das Dampfrohr (1) hineinragendes Düsenrohr (3). Die Zuführarmatur (2) beinhaltet ein den Wasserdruck (P2) im Düsenrohr (3) einstellendes Regelventil (4) und das Düsenrohr (3) weist mindestens eine sich in Abhängigkeit vom Wasser- und Dampfdruck (P2,P1) einstellende Düse (5) auf. Die Düse (5) oder Düsen (5) sind im Düsenrohr (3) quer zur Längsrichtung des Düsenrohres (3) und in Längsrichtung des Dampfrohres (1) angeordnet. <IMAGE>
