Description

Schwimmer. Die Erfindung betrifft einen Schwimmer, wie er im Maschinenbau- für die Einleitung von Bewegungen in Abhängigkeit von einem Flüssigkeitsstande Verwendung findet. Schwimmer, welche als geschlossene-Hohlkörper ausgeführt sind und unter äußerem Druck arbeiten müssen, sind der Gefahr ausgesetzt, zusammengedrückt zu werden. Es kann z. B. durch entsprechende Verstärkung der Wandungen des Schwimmkörpers dieser Gefahr begegnet werden. Ebenfalls bereits bekannt ist es, in den Schwimmer ein wenigstens bei verminderter Temperatur teilweile in flüssigem Zustand sich befindendes Mittel einzufüllen, das durch Verdampfung den Druckausgleich bewirken soll. In jedem Fall wird jedoch die Auftriebskraft des Schwimmers erheblich geschwächt. Sodann kann es bei der Verwendung derart angefüllter Schwimmer für Dampfkessel vorkommen, daß der Schwimmer infolge der besonderen Natur des Dampfkessels in kalte Wasserschichten eintaucht, wodurch die Schwimmerflüssigkeit nicht zur Verdampfung gelangt, und somit gar kein oder nur ein ungenügender Druckausgleich zur Wirkung kommt.Swimmer. The invention relates to a float as used in mechanical engineering for the initiation of movements depending on a liquid level use finds. Floats, which are designed as a closed hollow body and under external pressure are exposed to the risk of being squeezed. It can e.g. B. by appropriate reinforcement of the walls of the float this Danger to be met. It is also already known to have at least one in the swimmer means that is partly in a liquid state at a reduced temperature to be filled in, which is to effect pressure equalization through evaporation. In any case however, the buoyancy of the swimmer is considerably weakened. Then can it can happen when using floats for steam boilers that are filled in such a way that the swimmer in cold water layers due to the special nature of the steam boiler immersed, so that the float liquid does not evaporate, and thus No or insufficient pressure equalization comes into effect.

Statt dessen steht das Innere des Schwimmers nach vorliegender Erfindung unter Druck eines eingefüllten Gases. Die Auftriebskraft wird dadurch, weil die Flüssigkeitsfüllung fehlt, nicht beeinträchtigt.Instead, there is the interior of the float according to the present invention under pressure of a filled gas. The buoyancy is because the Liquid filling missing, not impaired.

Der Druck im Innern des Schwimmers braucht bei drucklosem Zustand von außen nicht unbedingt gleich dem im Betriebe vorkommenden Außendruck gewählt zu werden, da wenigstens bei Dampfkesseln mit dem Wachsen des Außendruckes durch Temperatursteigerung auch der Druck -im Innern des Schwimmkörpers gesteigert wird.The pressure inside the float needs when it is depressurized from the outside not necessarily chosen to be the same as the external pressure occurring in the company to become, because at least in the case of steam boilers, with the increase in external pressure Temperature increase also the pressure inside the float is increased.

PATENTANSPRÜCHE: r. Schwimmer in Form eines geschlossenen Hohlkörpers für Verwendung in Druckräumen, insbesondere von Dampfkesseln, dadurch gekennzeichnet, daß das Innere des Schwimmers unter Druck eines eingefüllten Gases steht. a. Schwimmer nach Anspruch s, dadurch gekennzeichnet, daß zur Verwendung des Schwimmers in Räumen mit zunehmendem Druck infolge Temperatursteigerung der Anfangsdruck des Gases im Schwimmer kleiner gewählt ist als der Außendruck, wobei dann der Innendruck mit der mit wachsendem Außendruck zunehmenden Temperatur sich ebenfalls erhöht.PATENT CLAIMS: r. Float in the form of a closed hollow body for use in pressure rooms, especially steam boilers, characterized in that that the interior of the float is under pressure of a gas filled therein. a. swimmer according to claim s, characterized in that the float is used in rooms with increasing pressure as a result of temperature increase, the initial pressure of the gas in the The float is selected to be smaller than the external pressure, with the internal pressure then also being included the temperature, which increases with increasing external pressure, also increases.
