Definitions

  • the invention relates to a so-called heating circuit distributor for Connection to a liquid heater, especially a boiler from a housing with heating and heating circuit side Flow and return connections in the housing through channels with each other are connected, which in turn through connection areas for a heating circuit pump and an admixing valve are.
  • heating circuit distributors are well known and in use, so that no special printed evidence is required per se.
  • heating circuit distributors are also designed in the form of cast blocks which are in themselves uniform. It is also known and customary to integrate such heating circuit distributors directly behind the heating circuit-side supply and return connections in the supply and return lines coming from them, a line connecting the two lines with overflow valve. The arrangement of such overflow valves in a bypass line between the outgoing supply and return lines is also known on heating circuit distributors which represent pure line constructions, whereby line areas can be partially cast in one piece.
  • overflow lines equipped with an overflow valve is to ensure sufficient minimum circulation at partial load or, for example, even when all the radiator valves in a heating circuit are closed while the pump is still running, i.e. this measure can cause disturbing flow noises in the partial load range caused by impermissible pressure increases a central heating system can be avoided.
  • a minimum quantity of circulating water is retained when the thermostatic valves on the radiators are closed.
  • a heating circuit distributor of the type mentioned at the outset i.e. those in the aforementioned To simplify block construction of cast iron and to improve that this effort while ensuring the same Function is largely unnecessary, and connected with the proviso is the overflow line of such a heating circuit distributor without great effort when not in use do.
  • This task is with a heating circuit distributor of the generic type Kind according to the invention solved in that in the housing between the ducts on the pressure side behind the connection area the heating circuit pump an overflow opening connecting both channels arranged and this a plug or a Differential pressure relief valve is assigned.
  • this solution is advantageously implemented in such a way that a connection opening for the sealing plug or the overflow valve is arranged on the housing in alignment with the overflow opening and that, furthermore, in the duct leading to the heating flow connection, the pressure-side space behind the pump is formed by a wall in the form of a step from the return leading channel separated and in this wall the overflow opening designed in the form of a valve seat is arranged.
  • the connection opening on the housing is equipped with an internal thread and the sealing plug and the differential pressure overflow valve are provided with corresponding external threads that match the internal thread.
  • the heating circuit distributor according to the invention is based on the following the graphic representation of an embodiment explained in more detail.
  • the heating circuit distributor for connection to liquid heaters For example, a boiler still consists of a housing 1 with supply and return connections on the heater and heating circuit side 2,3; 4,5, which in the housing 1 through channels 6,7 with each other are connected, which in turn through connection areas 8.8 'for a heating circuit pump P and an admixing valve MV are led.
  • an overflow opening 9 connecting the two channels 6, 7 is arranged in the housing 1 between the channels 6, 7, namely on the pressure side behind the connection area 8 of the heating circuit pump P, and this has a sealing plug 10 or a differential pressure overflow valve 11 is assigned. If such a heating circuit distributor is supplied with a plug 10 inserted, this can then be replaced at any time by a differential pressure overflow valve 11 if necessary.
  • a connection opening 12 for the sealing plug 10 or the overflow valve 11 is arranged on the housing 1 in axial alignment with the overflow opening 9.
  • connection opening 12 on the housing 1 is provided with an internal thread, and the sealing plug 10 and the overflow valve 11 have corresponding external threads that match the internal thread.
  • connection opening 12 and the overflow opening 9 are advantageously in one plane with their axes, so that the necessary machining operations can be carried out from one side in one clamping of the housing 1.
