Definitions

  • the invention relates to a device for regulating the circulation in a temperature-loaded media circuit having tapping points with, for example, hot process water leading section containing the tapping points and a section guiding the return of the process water.
  • the temperature-sensitive element of the circulation control valve consists of at least one convexly pre-bent bimetallic disc that jumps into a concave deflection when heated and returns to the convex deflection when it cools down.
  • Such disks can be constructed very inexpensively and do not require any control effort, since they are controlled by the temperature of the medium itself.
  • several such bimetallic discs can be arranged in series in the circulation control valve.
  • the cover (37) which closes the housing (34) is the second abutment for the spring element (42).
  • a timer (61) is fastened on the circulation control valve (6) via a holding bracket (60).
  • This can consist, for example, of a synchronous motor which circulates a magnet (62), which is fastened on a disk (63), in a twenty-four hour cycle.
  • the magnetic forces of the magnet (62) act on a magnet (64) which is firmly connected to a plunger (65).
  • This acts via the temperature-sensitive element (10) on the valve cover (18) and urges it against the valve seat (17).
  • the circulation control valve (6) is thus closed, although the temperature-sensitive element with its cooled bimetallic discs (23, 24) would in itself release the flow for the medium (11).
  • the temperature-sensitive element (10) again determines the circulation in the media circuit.
  • the return lines which generally have a smaller cross-section, are better protected against erosion damage and contamination or deposits due to the lower temperature level and the lower throughput.
  • the circulation control valve is arranged behind the last extraction point, it is also relatively well protected against contamination, deposits and erosion damage. In addition, it can prevent backflow at this installation location, so that when opening the medium can not flow to a tapping point via the return lines of the tapping point. Regardless of the position of the circulation control valve, for example the valve cover (18) would lie on the valve seat (17) and prevent the backflow (FIG. 10).
  • the circulating volume flowing through the return line and the resulting heat losses are so small that it makes sense, for example, in a domestic water system in a tenement building as a result of the invention, to incorporate quantity meters in branched line systems in the feeds for the purpose of hot water cost calculations without the line branches , which have the lower flow resistance as a whole, are impermissibly disadvantaged.
  • the invention also enables the automatic tuning of branched circuits when only one pump is installed in the common part of the return line.
