Definitions

  • the present invention relates to a connection fitting with the preamble features of claim 1, as known from EP 1 882 784 A1 is known.
  • the present invention further relates to a drinking and service water system.
  • connection fitting of the aforementioned type to arranged in a connected via this connection fitting ring line when removing drinking or service water via a downstream flow direction Consumer to achieve a loop flow.
  • a partial flow of the strand is led out at the Ausfädelömie the connection fitting and passed over the ring line to the at least one connected to the ring line consumer.
  • the ring line opens into the threading of the connection fitting.
  • each main line is understood, regardless of whether this extends within a floor and within the floor several successively arranged wet cells supplied via a ring line with drinking or service water, or as riser cabinet, for example, in several stories superimposed Connecting wet cells with each other.
  • connection fitting of the aforementioned type is known as part of an ultrapure water supply system.
  • connection fitting the recirculated from the loop in the strand loop flow is introduced at an angle of about 90 ° to the main flow direction in the connection fitting.
  • the return of the loop flow takes place via a threading opening arranged in a cross-sectional constriction.
  • the threading opening is therefore provided in an area with the lowest pressure. Since the cross-sectional constriction in the manner of a Venturi nozzle acts and causes the above-described pressure difference between the Aus- and Einfädelötechnisch, directed by the Ausfädelö réelle to the threading flow when removing drinking or service water.
  • the generated flow is therefore directional.
  • This is the from the DE 39 19 074 A1 previously known connection fitting for drinking or service water systems unsuitable, in which a flow through the strand is provided as needed in one or the other direction.
  • connection fitting differs from the above-described connection fitting substantially in that the threading is provided in the region of a diffuser and the recirculation flow recirculated from the loop line is introduced at an angle of not more than 75 ° to the main flow direction.
  • This connection fitting is also unsuitable for a drinking or service water system with intended flow reversal, as in the case of flow reversal desired in the loop purge effect is drastically reduced or no longer exists, so that a flushing of subsequent connected to the strand loops can not be guaranteed safely.
  • Such a flow reversal can occur when the floor or riser pipe is also formed as a ring and the removal of drinking or service water in one of the connected to the floor or riser ring lines a flow in both the upstream and the downstream Connecting fittings causes.
  • the present invention is based on the problem of specifying a connection fitting for connecting a ring line with at least one consumer on a floor or riser or ring, with a reliable flushing effect of the loop can be achieved even with flow reversal, and to provide a drinking or domestic water system which uses such a connection fitting.

  • the inventive arrangement of the inlet and Ausfädelö réelle allows a flow through the connection fitting in both directions such that a desired flushing effect of the ring lines is ensured regardless of the prevailing flow in the strand. In other words, when removing drinking or service water to a consumer all in the flow direction in front of the strand connected ring lines can be flushed. It has been found to be advantageous that a conditional by the inventive arrangement of the inlet and Ausfädelö réelle pressure loss within the connection fitting, whereby several in the main flow direction one behind the other arranged connection fittings are tunable to each other taking into account a prevailing operating pressure in the strand, so that a sufficient Flushing effect of all loops remains guaranteed.

  • the inflow angle is preferably between 35 ° and 55 ° to the main flow direction.
  • the inflow angle between 42 ° and 47 ° relative to the main flow direction, which results in a relatively low pressure loss at the threading opening for a relative to the main flow direction aligned recirculated loop flow.

  • a flow passage area in the cross-sectional widening can be variably adjusted such that a passage area formed between the closure body and an inner wall of the cross-sectional constriction can be displaced by displacing the closure body can be increased or decreased in or against the main flow direction. In this way, a pressure difference adapted to different volume flows for generating a loop flow can be achieved in a simple manner.
  • the closure body closes the cross-sectional constriction at low flow rates up to a critical volume flow substantially sealing.
  • a critical volume flow is understood as meaning a volume flow which is sufficient to move the closure body in the main flow direction solely on the basis of frictional and compressive forces acting on the closure body.
