Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Vorrichtung, welche gestattet, bei Dampfheizungen bekannter Art, bei denen dem zur Heizung dienenden Dampf durch einen Düsenapparat Luft beigemischt wird, die Menge des einströmenden Dampfes und damit die Heizkörpertemperatur zu regeln. Die Erfindung besteht darin, daß das Dampfluftgemisch vor seinem Eintritt in den Heizkörper auf einen Ausdehnungskörper einwirkt, welcher eine Drosselvorrichtung für den frischen Dampf in der Weise beeinflußt, daß bei steigender Temperatur des Gemisches die Dampfeintrittsöffnung mehr verschlossen wird.The invention relates to a device which makes it possible to use steam heating systems Type in which air is added to the steam used for heating through a nozzle device, the amount of the inflowing To regulate the steam and thus the radiator temperature. The invention consists in that the vapor-air mixture before his Entry into the radiator acts on an expansion body, which has a throttle device for the fresh steam is influenced in such a way that the steam inlet opening increases as the temperature of the mixture rises more closed.

Die Zeichnung veranschaulicht die Anwendung der Erfindung bei einem Heizkörper. Der Dampf strömt durch die Leitung α und das Drosselventil b dem Injektor c zu, welcher aus der zur Entlüftung des Heizkörpers und zur Abführung des Kondensationswassers dienenden Leitung d durch das Rohr e Luft ansaugt, die mit dem Dampf durch das Rohr/, die Kammer g und das Rohr h dem Heizkörper zuströmt. . In der Kammer g befindet sich der Ausdehnungskörper i, an welchem die Stange k befestigt ist, die durch die Stopfbüchse / in das Gehäuse des Drosselventils b geführt und mit dem Kegel des Ventils verbunden ist.The drawing illustrates the application of the invention to a radiator. The steam flows through the line α and the throttle valve b to the injector c , which sucks in air from the line d , which is used for venting the radiator and for discharging the condensation water, through the pipe e , which with the steam through the pipe /, the chamber g and the pipe h flows towards the radiator. . In the chamber g is the expansion body i, to which the rod k is attached, which is guided through the stuffing box / into the housing of the throttle valve b and connected to the cone of the valve.

Bei steigender Temperatur des Dampfluftgemisches wird durch die Ausdehnung des Körpers i der dem Injektor zuströmende Dampf gedrosselt. Das in den Heizkörper eintretende Gemisch wird also ärmer an Dampf, und seine Temperatur sinkt infolgedessen. Die Regelungsvorrichtung arbeitet demnach auf die Erhaltung einer annähernd gleichbleibenden Heizkörpertemperatur hin.As the temperature of the steam-air mixture rises, the expansion of the body i throttles the steam flowing into the injector. The mixture entering the radiator becomes poorer in steam and its temperature drops as a result. The control device therefore works towards maintaining an approximately constant radiator temperature.

Anstatt jeden Heizkörper mit einem besonderen Injektor und einem eigenen Regelungsapparat zu verbinden, kann man natürlich auch für ein ganzes Heizungssystem oder eine größere Anzahl von Heizkörpern einen einzigen Injektor nebst zugehöriger Regelungsvorrichtung anordnen.Instead of each radiator with a special injector and its own control apparatus can of course also be used for an entire heating system or a large number of radiators Arrange single injector together with the associated control device.
