Shut-off valve housing and shut-off valve

1. A shutoff valve housing for installation in a sanitary device comprising

a water duct, which is arranged in the shutoff valve housing and has an inlet and an outlet,

wherein the shutoff valve housing comprises a housing element, made of plastic, and at least one connector element, made of metal, the at least one connector element being in connection with the housing element, wherein the water duct extends through the housing element and through the connector element,

wherein the connector element is configured as an insert part and the housing element as an injection molded part,

wherein the housing element is molded onto the connector element such that a one-piece shutoff valve housing is provided,

wherein the connector element comprises at least two, with respect to the water duct, opposite flats, which flats are part of the connector element and are made of metal, and

wherein the housing element comprises in the region of the flats corresponding recesses through which the flats are accessible.

2. The shutoff valve housing as claimed in claim 1 , wherein the shutoff valve housing comprises an inlet connector comprising the inlet, and an outlet connector comprising the outlet, and

wherein the connector element comprises the inlet connector or the outlet connector.

3. The shutoff valve housing as claimed in claim 1 , wherein the shutoff valve housing comprises an inlet connector comprising the inlet, and an outlet connector comprising the outlet, wherein solely the inlet connector comprises the metallic connector element, while the outlet connector and the housing element are made of plastic.

4. The shutoff valve housing as claimed in claim 1 , wherein the connector element, with a bore or opening, constitutes an extension of the water duct and a part of the housing wall of the water duct.

5. The shutoff valve housing as claimed in claim 1 , wherein the connector element at least partially encloses a housing wall of the water duct with a bore on a surface of the connector element facing away from the water duct.

6. The shutoff valve housing as claimed in claim 5 , wherein the housing element fully covers the surface of the connector element which is facing toward the water duct.

7. The shutoff valve housing as claimed in claim 1 , wherein the housing element and the connector element are integrally and/or positively connected to each other, forming a one-piece shutoff valve housing.

8. The shutoff valve housing as claimed in claim 1 , wherein the connector element and the housing element, respectively, comprise at least one connecting portion, by which at least one of the connecting portion, the connector element, and the housing element are in connection with each other.

9. The shutoff valve housing as claimed in claim 8 , wherein the connector element is at least partially surrounded in a region of the connecting portion, both on a side facing away from the water duct and on a side facing toward the water duct, by the housing element.

10. The shutoff valve housing as claimed in claim 1 , wherein the connector element projects in a region of the connecting portion into the housing element.

11. The shutoff valve housing as claimed in claim 1 , wherein the connector element comprises on a side facing toward the water duct a functional structure in the form of circumferential grooves running radially to the water duct, which functional structure improves the connection to the housing element, and/or wherein the connector element comprises on a side facing away from the water duct a functional structure in the form of circumferential grooves running axially to the water duct, which functional structure improves the connection to the housing element.

12. The shutoff valve housing as claimed in claim 11 , wherein said flats are arranged in the region of the functional structure.

13. The shutoff valve housing as claimed in claim 1 , wherein the shutoff valve housing is configured as an angle valve housing,

wherein the water duct has a deflection region, and

wherein the inlet connector runs at an angle to the outlet connector.

14. The shutoff valve housing as claimed in claim 1 , wherein in the water duct is arranged at least one valve seat for the cooperation of a valve tappet, and

wherein in the housing element is arranged at least one receiving portion for receiving the valve tappet.

15. The shutoff valve housing as claimed claim 1 , wherein the housing element and/or the connector element comprises a positioning portion for the positioning of the shutoff valve housing in a cistern, and/or wherein the housing element and/or the connector element comprises a fastening portion, via which the shutoff valve housing is fastenable with a fastening element to a cistern, and/or wherein the connector element comprises on the outer side a thread.

16. A shutoff valve, in particular an angle valve, comprising a shutoff valve housing as claimed in claim 1 , wherein a valve tappet is arranged in the water duct.

17. A cistern arrangement comprising a cistern having a receptacle for the fastening of a shutoff valve as claimed in claim 16 .

18. A method for producing a shutoff valve housing as claimed in claim 1 , wherein the metal connector element is placed in an injection mold, and wherein the plastic housing element is subsequently molded onto the connector element.

19. The shutoff valve housing as claimed in claim 14 , wherein the receiving portion is a thread.
