Abstract

A configuration for installation into a pipeline of a fluid network. The configuration has a connection housing with an inlet, an outlet, and a connection opening for connection of an exchangeable functional unit. The connection housing has a rotatably arranged core piece whose rotation makes it possible for the throughflow of the fluid through the connection housing to be blocked and/or released. The core piece has a receptacle for connection of the functional unit, and the receptacle and the connection opening are oriented in the same direction.

First claim

The invention claimed is:

1. A configuration for installation into a pipeline of a fluid network, the configuration comprising:
an exchangeable functional unit;
a connection housing having an inlet, an outlet, and a connection opening formed therein for connection to said exchangeable functional unit;
a core piece rotatably disposed in said connection housing, a rotation of said core piece makes it possible for a throughflow of a fluid through said connection housing to be blocked or released, said core piece having a receptacle for connection of said exchangeable functional unit, said receptacle and said connection opening are oriented in a same direction;
said receptacle connected to said exchangeable functional unit such that rotation of said exchangeable functional unit rotates said core piece, to selectively release or block throughflow through said connection housing and said core piece;
said core piece being held rotatably in said connection housing by a holding ring;
said exchangeable functional unit having fasteners enabling a mechanically releasable connection of said exchangeable functional unit to said holding ring; and
said exchangeable functional unit is formed such that it is able to be locked in at least one rotational position to said holding ring.

2. The configuration according to claim 1 , wherein said inlet and said outlet are disposed along a throughflow axis, and a direction of connection of said exchangeable functional unit runs substantially orthogonally with respect to the throughflow axis.

3. The configuration according to claim 1 , wherein said core piece is inserted into said connection opening.

4. The configuration according to claim 1 , further comprising projections disposed on said exchangeable functional unit as said fasteners for establishing the mechanically releasable connection and the projections engage into corresponding recesses of said holding ring.

5. The configuration according to claim 1 , wherein said fasteners for establishing the mechanically releasable connection include a bayonet closure.

6. The configuration according to claim 1 , wherein said exchangeable functional unit has a seal which seals off said exchangeable functional unit with respect to said core piece.

7. The configuration according to claim 1 , wherein said exchangeable functional unit has a connection geometry.

8. The configuration according to claim 1 , wherein said exchangeable functional unit is selected from the group consisting of: a placeholder functional unit, a descaling functional unit, a filtering functional unit, a pressure reduction functional unit, a monitoring functional unit, a germ reduction functional unit, a functional unit for determining chemical and microbiological parameters, a functional unit for determining pH, electrical conductivity, nitrate, nitrite, sulphate, carbon dioxide, iron, fluoride, chlorine, copper, phosphate, silicon, ammonium, hardness, temperature, carbonate, salinity, germ content or metal content, data functional unit, a communication functional unit, a display functional unit and a function unit performing a combination of these recited units.

9. The configuration according to claim 1 , wherein said core piece has a core piece inlet and a core piece outlet disposed opposite said core piece inlet.

10. The configuration according to claim 9 , wherein said core piece inlet and said core piece outlet are in each case connected to said receptacle.

11. The configuration according to claim 9 , wherein by rotating said core piece inside said connection housing, said inlet and said outlet of said connection housing, and said core piece inlet and said core piece outlet of said core piece, are able to be brought into fluidic connection.

12. The configuration according to claim 9 , wherein said exchangeable functional unit has a throughflow channel which, in a connected state, is situated inside said core piece and is connected to said core piece inlet and said core piece outlet.

13. The configuration according to claim 1 , further comprising a sealing element for sealing off said connection housing with respect to said core piece, said sealing element is disposed in a region of said inlet and/or said outlet.

14. The configuration according to claim 13 , wherein said sealing element has a first seal which acts radially, against said connection housing, and a second seal which acts axially, against said core piece.
