Definitions

  • Such hydraulic assemblies are used, for example, in compact heating systems, such as gas boilers, or as apartment stations in central heating systems.
  • the task of these hydraulic assemblies is usually to route a liquid heat transfer medium such as water optionally through at least one heating circuit or a domestic water heat exchanger for heating domestic water.
  • EP 2 372 257 A2 discloses a heat distribution device which, in addition to a circulating pump, has a mixing valve for adjusting the temperature of a heating circuit and a heat exchanger for generating heated service water, a switching valve being provided to switch the heating medium flow between the heat exchanger and the heating circuit.
  • the lever In a central position of the valve element between the two valve seats, the lever preferably extends essentially normal to the axis along which the two valve seats face one another.
  • the pivot axis preferably extends transversely and in particular likewise normal to this axis, along which the two valve seats face one another. In this case, however, the pivot axis is along in the direction of the lever from the axis which the valve seats face each other, spaced apart.
  • the drive for moving the lever on the outside of the valve housing is preferably a linearly movable drive which moves along an axis transversely to the lever and can move or pivot it back and forth.
  • the drive is particularly preferably designed to be self-locking, so that it maintains the switch position of the lever and thus of the valve element even without power or energy supply.
  • the drive is more preferably an electric motor, in particular a stepping motor.
  • the positioning of the valve element of the mixing valve is preferably regulated as a function of temperature by a control device, for which purpose the outlet temperature of the heat transfer medium on the outlet side of the mixing valve can be detected by a temperature sensor.
