Description
Bei vielen Betrieben werden in Rohrführungen heiße Gase oder heiße Flüssigkeiten oder heiße Dämpfe geleitet. Diese Flüssigkeiten sollen durch äußere Beheizung der Rohrführungen in der Temperatur erhöht werden, und es besteht dann die Gefahr, daß innerhalb der Rohre durch zu starken Wärmestau in den Wandungen die Beanspruchungen das zulässige Maß überschreiten und schließlieh Brüche der Rohre herbeigeführt werden. Namentlich bei Hochdruckdampf anlagen hängt von der sicheren Heizungsmöglichkeit die Durchführung des Betriebes überhaupt ab.In many companies there are hot gases or hot liquids in pipe guides or direct hot vapors. These liquids are said to be due to external heating of the Pipe guides are increased in temperature, and there is then a risk that the stresses inside the pipes due to excessive heat build-up in the walls exceed the permissible dimension and ultimately break the pipes. In the case of high-pressure steam systems in particular, it depends on the safe heating option Implementation of the operation at all.
Im nachfolgenden soll eine neue Sicherungs- und Regelvorrichtung für Betriebe mit heißen Rohrführungen für Hochdruckdampfbetrieb beschrieben werden, durch welche die Gefahren solcher Betriebe nach Möglichkeit verhütet werden sollen. Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.In the following a new backup and control device for companies with hot pipe guides for high pressure steam operation are described by means of which the dangers of such operations are prevented as far as possible should be. An exemplary embodiment is shown in the drawing.
In einem Rohrnetze 1 soll ein heißes Medium geleitet und durch Heizgase von der Feuerstelle / aus beheizt werden. Zur Sicherung und Regelung der Heizungswirkung und zur Verhütung eines zu großen Wärmestaues in den Rohrwandungen wird von dem Rohrnetz 1 ein möglichst gerades Stück (Meßrohrstück 2) herausgegriffen, welches Meßrohrstück in den Zug der Feuergase gelegt und an der einen Seite mittels einer Klemm- oder ähnlichen Vorrichtung 3 ortfest, auf der anderen Seite aber in einer Führung 4 frei gleitend gehalten wird, so daß es sich frei ausdehnen kann. Zur Sicherung dieser Ausdehnungsmöglichkeit ohne Störung der Strömung in der Rohrführung wird das gerade Meßrohr stück an seinen beiden Seiten unter Zwischenschaltung von nachgiebigen und federnden Rohrbügeln oder Krümmern 5 mit dem andern Teil der Rohrführung verbunden. In a pipe network 1, a hot medium is to be passed and by heating gases from the Firepit to be heated / off. For securing and regulating the heating effect and to prevent excessive heat build-up in the pipe walls, the pipe network 1 is as straight as possible Piece (measuring tube piece 2) picked out which measuring tube piece in the train of the fire gases placed and fixed on one side by means of a clamping or similar device 3, but on the other side in one Guide 4 is held to slide freely so that it can expand freely. To secure this possibility of expansion without disturbing the flow in the pipe guide is the straight measuring tube piece on both sides with the interposition of flexible and resilient pipe brackets or bends 5 connected to the other part of the pipe guide.
Mit steigender Temperatur dehnt sich das Meßrohrstück 2 nach der Gleitseite 4 aus, und die Ausdehnung kann durch eine Stange 6 und einen in einem Lager 7 drehbaren Hebel 8 zur Anzeige der Dehnung, die als Maß für die Temperatursteigerung und den Wärmestau gilt, dienen.As the temperature rises, the measuring tube section 2 expands towards the sliding side 4, and the expansion can be achieved by a rod 6 and a lever 8 rotatable in a bearing 7 to display the elongation, which is a measure of the temperature increase and heat build-up applies, serve.
Es ist auch möglich, mit Hilfe einer Stange 9 und eines damit verbundenen Eisenkerns 10, welcher sich innerhalb von Spulen bewegt, die' Ausdehnung des Meßrohrstückes 2 elektromagnetisch mit Hilfe einer Stromquelle 12 und einer Anzeigevorrichtung in beliebiger Entfernung kenntlich zu machen.It is also possible with the help of a rod 9 and an iron core connected to it 10, which moves within coils, the 'expansion of the measuring tube piece 2 electromagnetically with the aid of a power source 12 and a display device to be identified at any distance.
Durch die Ausdehnung des Meßrohrstückes 2 kann aber auch unter Vermittlung einer Stange· 14 und eines Griffes 15 ein Absperrorgan 16 in der Zuführung des bei α zutretenden Brennstoffes derart bewegt werden, daß mit steigender Ausdehnung des Meßrohrstückes der Durchlaß im Absperrorgan allmählich verkleinert und schließlich in einer Grenzstellung der Zutritt des Brennstoffes zur Feuerstelle f ganz geschlossen wird.Due to the expansion of the measuring tube section 2, however, a shut-off element 16 in the supply of the fuel entering at α can also be moved with the help of a rod 14 and a handle 15 in such a way that, with increasing expansion of the measuring tube section, the passage in the shut-off element gradually decreases and finally in a Limit position of the access of the fuel to the fireplace f is completely closed.
In ähnlicher Weise lassen sich die verschiedenartigsten Signal- und Sicherheitseinrichtungen vom Meßrohrstück 2 aus zur Wirkung bringen.A wide variety of signaling and safety devices can be set up in a similar manner from the measuring tube section 2 to take effect.
