Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Das in Fig. 1 dargestellte Siederohr besteht aus einem geraden Rohre a, in welches an beiden Enden konisch abgedrehte Mundstücke b und c eingelöthet sind.The boiler tube shown in Fig. 1 consists of a straight tube a, in which conically twisted mouthpieces b and c are soldered at both ends.

Das obere Mundstück b wird von einem kupfernen Ring d dampfdicht umschlossen. Derselbe ist aufsen mit Gewinde versehen und hat oben einen Ansatz mit Einschnitten für den Schlüsselangriff. In einer Nuth dieses Ansatzes liegt eine Bleidichtung m, welche sich beim Einschrauben des Ringes d in die Rohrwand e so viel zusammenprefst, dafs beim Aufliegen des Ringes d auf dem Konus b auch das Gewinde gedichtet ist. Der untere Konus c sitzt direct in der Rohrwand/.The upper mouthpiece b is enclosed in a vapor-tight manner by a copper ring d. It is threaded on the outside and has a neck with notches on top for the key attack. In one groove of this approach there is a lead seal m which, when the ring d is screwed into the pipe wall e , compresses so much that when the ring d rests on the cone b , the thread is also sealed. The lower cone c sits directly in the pipe wall /.

Fig. 2 zeigt die Anbringung der Röhren in einem Dampfkessel. Die Feuergase werden in dem Feuerrohr g entwickelt und treffen dann in der Feuerkiste h sofort nur dünne Rohrwände, welche sie normal bestreichen müssen, während das Wasser in den letzteren durch die Erwärmung eine verticale Bewegung annimmt. Die abgekühlten Gase entweichen dann durch das Uebergangsrohr i direct in den Schornstein k. An der Seite der Feuerkiste befinden sich hohle Stehbolzen //, welche einerseits als Verankerung dienen, andererseits den Zweck haben, durch dieselben mittelst Dampfinjection die äufsere Röhrenfiäche von Rufs zu säubern.Fig. 2 shows the installation of the tubes in a steam boiler. The fire gases are developed g in the fire tube and then meet in the fire box h immediately only thin tube walls, which have to coat normal, while the water in the latter assumes a vertical movement by the heating. The cooled gases then escape through the transition pipe i directly into the chimney k. On the side of the fire box there are hollow stud bolts // which serve as anchoring on the one hand, and on the other hand have the purpose of cleaning the outer tube surface of ruffles by means of steam injection.

Bei gröfseren Kesseln (wie bei dem gezeich-■ neten), bei welchen der Raum unter der Feuerkiste genügend grofs ist, um befahren werden zu können, ist es nach Ansicht des Patentinhabers vortheilhaft, die Dichtungsschrauben in der unteren Rohrwand anzuordnen. Es ändert dies indessen nichts an der Rohrverbindung selbst.With larger boilers (like the one shown), where the space under the fire box is big enough to be driven on, according to the patent proprietor advantageous to arrange the sealing screws in the lower pipe wall. It changes However, this has nothing to do with the pipe connection itself.

Fig. 3 zeigt die Möglichkeit des Einsetzens der Röhren von dem Innern der Feuerkiste aus.Fig. 3 shows the possibility of inserting the tubes from inside the fire box.

Die Vortheile dieser Siederohrdichtung sollen folgende sein:The advantages of this boiler pipe seal are said to be as follows:

1. durch die Möglichkeit des Einsetzens der Röhren von dem Innern der Feuerkiste aus ist über der Feuerkiste kein höherer Raum nothwendig, als erforderlich ist, um in liegender Stellung die Dichtungsringe einschrauben zu können;1. by the possibility of inserting the tubes from inside the fire box No higher space is necessary above the fire box than is necessary in order to be in a lying position Position to be able to screw in the sealing rings;

2. das Dichthalten der Verschlüsse wird durch den Dampfdruck befördert, da dieser die beiden Rohrplatten fest gegen die konischen Enden anprefst;2. The tightness of the closures is promoted by the steam pressure, as this is the two Presses tube plates firmly against the conical ends;

3. die geraden Rohrwände der Feuerkiste brauchen nicht verankert zu werden, da jedes Rohr für sich als Säule den auf dasselbe entfallenden Dampfdruck überträgt;3. The straight pipe walls of the fire box do not need to be anchored, as each Tube for itself as a column transfers the vapor pressure allotted to the same;

4. Die Reinigung des Kessels von Kesselstein kann nach dem Herausnehmen der Röhren sehr bequem und vollständig bewirkt werden, ebenso der Ersatz etwa schadhafter Röhren.4. The boiler can be cleaned of scale after removing the tubes can be carried out conveniently and completely, as can the replacement of damaged tubes.
