Definitions

  • the present invention relates to an adapter for Connection of a hydraulic device to a heating or Cooling system with a housing that has at least two connection openings for connecting a flow line and a return line has, the connection openings in the housing flow out.
  • the invention also relates to a hydraulic Device, namely an electrically operated pump, especially a centrifugal pump, for pumping a medium in the heating or cooling system, which is a pump chamber with a Has inlet and an outlet, being within the Pump chamber an impeller is arranged.
  • Hydraulic devices are also known which include a Have hydraulic part that is introduced into the lines and on which a mechanically operable control panel or electrically operated actuator is attached.
  • the Actuator or control unit can be replaced without the hydraulic part being removed from the line.
  • the hydraulic part acts as an adapter for the actuator or the attached control panel.
  • Centrifugal pumps in particular are hydraulic devices known in a variety of embodiments and become many used in heating circuits in buildings.
  • the pump is in a suitable place, for example in Flow near the boiler, the pipe system interrupted and before the pump by means of flanges at the pipe ends is connected.
  • Pumps are also known in which the hydraulic part from the electrical part through a containment shell is separated so that the electrical part for maintenance purposes is exchanged while the hydraulic part in the system can remain.
  • the object of the invention is on the one hand, a constructive simple and therefore inexpensive adapter to create the Possibility of using different types of hydraulic Offers devices and the exchange of the Device without draining the heating or cooling system enables. It is also an object of the invention to provide a electrically operated pump as hydraulic devices too create, which are connected to the system via the adapter can and which is great with little design effort Reliability, high ease of maintenance and so a great cost saving guaranteed.
  • the particular advantage of the adapter according to the invention is that it can be used anywhere in the system and on site the possibility of connecting any hydraulic Device for example of a thermostatic valve or Pump offers.
  • the adapter according to the invention acts in the Kind of a lock, the housing interior being the Lock chamber forms, first by closing the Connection openings by means of the shut-off part from the pipe system is decoupled before this is now only a residual amount housing containing tap water is opened.
