Abstract

A hydraulic control and/or safety device, particularly for utility apparatuses or systems or appliances, which is preferably able to carry out a flow shut-off and/or limitation, particularly in the event of fault of the utility apparatus or system or appliance, and/or one or more features that improve the device and/or the apparatus performance. In particular, the device can carry out the function of the fluid treatment, so as to be particularly reliable, as it prevents at least the formation of deposits on its mechanical components designed to limit the water flow.

First claim

The invention claimed is:

1. A control or safety device for hydraulic apparatuses or systems, said device comprising:
a body in which there is a water path extending between an inlet or an inlet fitting and an outlet or an outlet fitting;
a water control and/or shut-off means arranged between said inlet or inlet fitting and said outlet or outlet fitting, the water control and/or shut-off means being adapted to count a flow of water and to block the flow of water flowing through the body in an event of a fault of the hydraulic apparatuses or systems or when a pre-set amount of the water has been supplied;
an insert disposed within the body; and
water treating parts that are active along said water path, the water treating parts comprising one or more permanent magnets that are inserted into the insert and that operate to prevent limestone formation on the water control and/or shut-off means, and
wherein said water treating parts are located upstream and/or in a proximity of the water control and/or shut-off means.

2. The device according to claim 1 , wherein at least a part of the water treating parts is associated and/or integrated with the body and/or with a part of the water control and/or shut-off means.

3. The device according to claim 1 , wherein a portion of the water treating parts is moulded or is made of polymer or plastic material charged with a charge.

4. The device according to claim 3 , wherein the charge is a ferromagnetic charge and/or an anti-microbial charge.

5. The device according to claim 1 , wherein the water treating parts are arranged in connection with the water control and/or shut-off means.

6. The device according to claim 1 , comprising:
the insert, which is adapted to define a seat or a hollow portion for housing the water treating parts, and
wherein an interspace is arranged around the hollow portion in which the water flows, the interspace being in fluidic communication with a passage seat towards the water control and/or shut-off means.

7. The device according to claim 6 , wherein the insert comprises a distribution chamber or cavity and/or holes or apertures for distributing the water flow in a substantially uniform manner into the interspace.

8. The device according to claim 6 , wherein the interspace determines a substantially laminar or thinner flow at the water treating parts.

9. The device according to claim 8 , wherein the water treating parts comprise an active core comprising a plurality of treating elements.

10. The device according to claim 1 , wherein the water treating parts comprise an active core comprising a plurality of treating elements.

11. The device according to claim 10 , wherein the plurality of treating elements include magnetic or anti-limestone treating elements and anti-microbial treating elements.

12. The device according to claim 1 , wherein the body or a part thereof comprises or is associated with magnetic or ferromagnetic material, cooperating with a magnetic treating core or means provided in the insert to concentrate a magnetic flux in predefined water passage areas.

13. The device according to claim 1 , wherein the water treating parts comprise tablets and/or cartridges comprising disinfectant or filtering substances.

14. The device according to claim 1 , wherein the insert houses the water treating parts and is provided with fitting means for connecting to a tap and/or to a pipe and/or to one or more water mains,
wherein the insert is coupled to the body, and
wherein at least one of the insert and the body is provided with engaging means for a fastening tool, for a purpose of coupling the device to said tap and/or pipe and/or one or more water mains.

15. The device according to claim 1 , wherein the insert includes a casing comprising a hollow portion that receives the water fed to the device, and
wherein the casing, when inserted with the insert into the body, forms an interspace for the water to flow between the casing and an upper half-body of the body, the casing being provided with a plurality of apertures for passage of the water from the hollow portion of the casing outwardly towards the interspace, each aperture included in the plurality of apertures being arranged in a substantially radial direction relative to an axis of the insert such that the water is distributed along a perimeter of the interspace.

16. The device according to claim 1 , wherein the water treating parts further comprise an anti-microbial treating means of a type in which ions and/or ionic substances are released into the water flow.

17. The device according to claim 1 , wherein at least part of the water treating parts is associable with and/or removable from the body or applied to the body at the inlet.

18. The device of claim 1 , wherein the insert comprises a casing having a hollow portion and a closing bottom applied to an end portion of the casing to close off the hollow portion and stably house the one or more permanent magnets that are disposed within the hollow portion of the casing.

19. The device of claim 18 , wherein the water path extends around an outer periphery of the casing which houses the one or more permanent magnets.

20. The device of claim 18 , wherein the casing forms only a part, but not an entirety, of a length of the insert such that the water path extends through a different part of the insert prior to reaching the casing.

21. The device of claim 1 , wherein:
the body comprises a lower half-body and an upper half-body,
the water control and/or shut-off means is disposed within the lower half-body, and
the insert is removably disposed within the upper half-body of the body.

22. A control and/or treatment device for hydraulic apparatuses or systems, said device comprising:
a body in which there is a water path extending between an inlet and an outlet;
a water control and/or shut-off means arranged between said inlet and said outlet, said water control and/or shut-off means being adapted to count a flow of water when passing through the water path;
an insert disposed within the body; and
anti-microbial treating means at least partly made of a polymer or thermoplastic material or of a polymer or thermoplastic material charged with treating sub stances,
an anti-limestone treating means comprising one or more permanent magnets that are disposed within the insert and that operate to prevent limestone formation on the water control and/or shut-off means,
wherein the anti-microbial treating means comprises at least one silver-based substance or charge adapted to release Ag+ ions, or comprises proteins or nanomaterials or copper alloys,
wherein the anti-microbial treating means releases ions and/or ionic substances into a flow of water when the flow of water is flowing through the body,
wherein an interspace of the body is structured to cause at least a part of a flow of water to flow in a substantially laminar manner when flowing through the body,
wherein said anti-microbial treating means and said anti-limestone treating means are located upstream and/or in a proximity of the water control and/or shut-off means.

23. The device according to claim 22 , wherein the insert includes a casing comprising a hollow portion that receives water fed to the device, and
wherein the casing, when inserted with the insert into the body, forms the interspace for water to flow between the casing and an upper half-body of the body, the casing being provided with a plurality of apertures for
