Definitions

  • the end of the tubes 5 that is located in the tube disk 3 is first expanded hydraulically.
  • the tube 5, which is pressed onto the respective bore of the tube disk 3 and against a depression formed in the area thereof, is then welded to the outside of the tube disk 3.
  • the weld 7 used for securing the position and sealing can be seen in FIG.
  • the pipes 5 can also be fastened in the pipe disk 3 by rolling in or only by welding.
  • the cylindrical probe body 6a of the expansion probe 6 is now inserted into the still free end of the tube 5 such that the sealing rings 10, which are spaced apart from one another on this probe body 6a, are just within the wall thickness of the tubular disc 4.
  • a housing ring 11 is screwed onto the housing of the expansion probe 6, the end face 11a of which bears against the outer surface of the tubular disk 4.
  • a stop ring 12 is arranged in the interior of the housing ring 12, from whose front end face one or more contact pins 12a protrude, the front face of which lies at a predetermined distance a from the tubular disk 4.
  • this distance a corresponds at the same time to the length difference to be generated by heating the tube 5, which in turn is responsible for the occurrence of a prestress in the tube 5 welded between the tube disks 3 and 4 after the tube 5 has been fastened and cooled.
  • FIGS. 9 and 10 show two further design options for the switch 13 for controlling the valve 14. While in the embodiment according to FIGS. 6 and 7, the contact pins 12a in the electrically non-conductive stop ring 12 are installed in the circuit of the switch 13 in such a way that, when they come into contact with the end edge of the expanding tube 5, the switch 13 is actuated, the embodiment according to FIG. 9 instead of a stop ring 12 with contact pins 12a a switch lever 20 pivotally mounted on the housing ring 11, which cooperates with a contact 19 of the switch 13. Normally, the switching lever 20 loaded by the spring 20a is lifted off the contact 19. If the shift lever 20 is pivoted clockwise from the expanding end edge of the tube 5 according to FIG. 9, it comes to rest on the contact 19 as soon as the tube 5 has expanded by the dimension a, as shown in FIG. At this moment, the switch 13 causes the valve 14 to open, as described above with regard to the first exemplary embodiment.
  • the switching process is triggered by an induction coil 21 arranged in the housing ring 11.
  • an induction coil 21 arranged in the housing ring 11.
  • This embodiment can also be used to make contactless contact if, instead of the magnetic ring 23, the part of the tube 5 emerging from the tubular disk 2 is used to trigger the signal to be emitted by the induction coil 21.
