Definitions

  • the invention relates to a heater with a Reversing valve according to the genus of the main claim.
  • a Reversing valve There are known as combi heaters with two heating circuits, optionally with the help of a reversing valve (3-way valve) between operating a room heater and Can switch domestic water heating. It is Reversing valve etc. due to the thermally lower Load arranged in the return of the two heating circuits.
  • the heater of the invention with the features of The main claim has the advantage that the closure body of the valve member press the closure body in Load direction towards the valve seats.
  • the actuator therefore only needs a while moving the valve member Apply strength.
  • Figure 1 schematically shows a heater and Figure 2 schematically a reversing valve.
  • a heater 10 is shown with a Heat exchanger 12 from an energy source 14 with heat is supplied.
  • An interior leads through the heater 10 Pipe system 16, within which the Heat exchanger 12 is arranged.
  • the piping system 16 has a reversing valve 18 arranged in the flow, from which a first pipeline 20 to one in the heater 10 arranged heat exchanger system 22 and from there a junction 24 leads.
  • a second pipeline string 26 leaves the heater 10 and leads to a schematic heating circuit 28 shown, from there back to the heater 10 and also to branch 24.
  • the heat exchanger system 22 is used for hot water preparation and the heating circuit 28 is used to operate room heating.
  • the heater 10 In the heater 10 is also a heating water promoting Pump 30 integrated into the inner piping system 16.
  • the pump 30 is located between the branch 24 and the Heat exchanger 12.
  • the reversing valve 18 is in the flow of the piping system 16 arranged.
  • the reversing valve 18 a housing 31 with three connections 32, 34, 36.
  • the connection 32 with the heat exchanger 12 the connection 34 with the heat exchanger system 22 and the connection 36 with connected to the heating circuit 28.
  • the port 32 fluidically seen as an input and ports 34 and 36 defined as outputs.
  • a valve member 38 is arranged within the housing 31, which has a closure body 40, the Closure body 40 corresponds to valve seats 42, 44.
  • the closure body 40 is connected to a rod 46, arranged on one side in a connection 34 Bearing 48 is slidably held.
  • An extension 50 protrudes into a coil 52, which is laterally attached to the housing 31. Between the coil 52 and the closure body 40 is inserted a spring 54. The elongated rod 50, the spool 52 and the spring 54 together form an actuator 56.
  • Heater 10 and reversing valve 18 operate as follows:
  • the heating medium flows into the pipeline string 26 and via the inlet 32 of the reversing valve 18 it flows to the Output 36 of the reversing valve 18, since the closure body 40 is lifted off the valve seat 44 and on the valve seat 42 lies on. From there, the heating medium passes through the heating circuit 28 and via the branch 24 to the input of the pump 30 and the cycle is closed.
  • the one generated by the pump 30 Pressure prevails in the piping system 16 through the Heat exchanger 12 up to the inlet 32 of the reversing valve 18 away.
  • the pump pressure does not act against the closing direction of the Valve member 38.
  • the spring 54 of the actuator 56 is dimensioned so that when the coil 50 is de-energized, presses the closure body 40 against the valve seat 42.
  • the pump 30 is switched off and after 1 to 2s Waiting time, the electrical coil 52 activated and the Extension 50 pulled into the coil 52.
  • the closure body 40 stands out from the valve seat 42 and is against the Valve seat 44 pressed (shown in dashed lines). The Heating medium thus flows through the heat transfer system 22.
  • the pump can also be switched operated with reduced power.
