Definitions

  • Such decentrally arranged pumps have been known for a short time. she replace the previously common central pump, which is located near a boiler is arranged and mostly supplies the heating system of a building alone.
  • the decentralized pumps attached to the radiator in particular have the Advantage that their performance can be adapted to the needs of the radiator and make an energy-saving, needs-based supply possible.
  • disadvantage of the pumps known to date is that special adapters are required for their assembly are that have to be integrated into the piping system as separate components. Retrofitting existing heating systems with the pumps mentioned is therefore comparatively complex.
  • the pump according to the invention ultimately takes on the same function as that Thermostatic valve, namely the hot water flow through the radiator
  • the Operation of the pump is similar to the operation of the thermostatic valve, so that the user is unable to determine any significant difference.
  • the electric motor can be handled by a rotatably mounted Ring, which is equipped with a scale like an adjustment knob and when it is rotated, a control variable relevant for motor control, for example, a target temperature is changed. So for the user is a greatest possible ease of use with an appealing design of the pump given.
  • the pump is hidden inconspicuously in the guise of the user Thermostatic valve.
  • FIG 1 the "simple" form of the centrifugal pump according to the invention in installed condition shown.
  • the corner of a radiator 1 as shown is shown is well known.
  • the flow line supplying the radiator points a knee with a flange, which is intended for the installation of a corner valve.
  • This forms a spherical valve housing 2 into which an inlet line 3 protrudes with its nozzle 7 and into which a drain line 4 opens.
  • the valve housing 2 arranged within the facing 6 of the radiator 1 also has a suitable for connecting a thermostatic valve Connection piece 5 with end flange, which protrudes from the facing 6, the connecting piece 5 is welded to the facing 6.
  • the pump itself has a drive on its electrical side Electric motor 8 and on the hydraulic side a held on the shaft 9 Impeller 10 on.
  • the impeller 10 sits with its central suction mouth 11 directly on the nozzle 7 of the inlet line 3 and thus takes the position and in a way in the valve housing 2 the function of a valve member in covering state, wherein the valve housing 2 which the impeller 10th surrounding impeller chamber forms.
  • On the hydraulic side of the pump is in End shield 13 an external thread 12 is provided, which forms a closure means and by means of which the pump can be screwed onto the valve housing 2.
  • To the Screwing in the connecting piece 5 has a corresponding internal thread.
  • the seal between the pump and the connector 5 is done by means of an O-ring 14.
  • the dimensions of the screw-in pump are adapted according to the existing circumstances.
  • Figure 2 also shows the corner of a radiator 1 with one in it located spherical valve housing 2.
  • the pump by means of an adapter forming an impeller chamber 15 16 screwed to the connecting piece 5, the adapter 16 the Inlet line 3 to the suction mouth 11 of the impeller 17 with an attachment 18 extended.
  • the attachment 18 has a pipe section 19 which is connected to the connector 7 is attached.
  • the attachment 18 has a hydraulic insert 20 which with its hole forms the inlet to the suction mouth and the one with its hydrodynamically designed surface forms an outlet channel and Defines the geometry of the impeller chamber 15. The outlet of the impeller chamber Ultimately opens axially in the valve housing 2 and thus in the drain line 4.
