Abstract

A boiler loop system including a primary-secondary piping loop interface apparatus having unitary construction including a flow diversion device, and a drain valve and a drain port in branches from a circumferential sidewall. In an embodiment, supply branch piping and return branch piping connect the primary-secondary piping loop interface apparatus to a boiler and provide attachment points for auxiliary plumbing equipment. In an embodiment, the boiler loop is integrated into the primary loop.

Claims

1. A primary-secondary piping system, comprising:

a primary piping loop;

a near boiler piping loop;

a secondary piping loop;

a primary-near boiler piping loop interface apparatus comprising;

a first tubular fluid conduit having a first circumferential sidewall having a first end and a second end,

first and second neck portions extending substantially perpendicular from the circumferential sidewall and being substantially parallel to each other, wherein each neck portion comprises a drain valve portion extending from the neck portion, including a drain shut-off valve and a drain port, and

first and second flow diversion devices disposed in the first and second neck portions, respectively, wherein each flow diversion device forms a first flow path between the tubular fluid conduit and the neck in a first position and a second flow path between the drain valve portion and the neck in a second position; and

a primary-secondary piping loop interface apparatus comprising;

a second tubular fluid conduit having a second circumferential sidewall having a first end and a second end,

first and second neck portions extending substantially perpendicular from the second circumferential sidewall and being substantially parallel to each other, wherein each neck portion comprises a drain valve portion extending from the neck portion, including a drain shut-off valve and a drain port, and

first and second flow diversion devices disposed in the first and second neck portions, respectively, wherein each flow diversion device forms a first flow path between the second tubular fluid conduit and the neck in a first position and a second flow path between the drain valve portion and the neck in a second position.

2. The primary-secondary piping system of claim 1, further comprising a boiler operatively connected to the near boiler piping loop.

3. The primary-secondary piping system of claim 2, further comprising a near boiler piping loop circulation pump.

4. The primary-secondary piping system of claim 3, wherein the near boiler piping loop circulation pump is incorporated internally within the boiler.

5. The primary-secondary piping system of claim 3, wherein the near boiler piping loop circulation pump is external to the boiler.

6. The primary-secondary piping system of claim 5, wherein the first or second neck portion of the primary-near boiler piping loop interface apparatus comprises a flange to interface with the near boiler piping loop circulation pump.

7. The primary-secondary piping system of claim 6, wherein the flange is rotatable.

9. The primary-secondary piping system of claim 8, wherein the first or second neck portion of the primary-secondary piping loop interface apparatus comprises a flange to interface with the secondary piping loop circulation pump.

10. The primary-secondary piping system of claim 9, wherein the flange is rotatable.

11. The primary-secondary piping system of claim 1, further comprising a primary loop circulation pump operatively connected to the primary piping loop.

12. The primary-secondary piping system of claim 1, further comprising a plurality of secondary piping loops comprising a plurality of primary-secondary piping loop interface apparatus.

13. The primary secondary piping system of claim 12, wherein each of the plurality of secondary piping loops constituting a separate heating zone.

14. The primary-secondary piping system of claim 12, wherein each of the plurality of secondary piping loops comprises a secondary piping loop circulation pump.

15. The primary-secondary piping system of claim 1, wherein the primary-near boiler piping loop interface apparatus and the primary-secondary piping loop interface apparatus are each constructed as a single unit.

16. A primary-secondary piping system, comprising:

a primary piping loop;

a secondary piping loop; and

a primary-secondary piping loop interface apparatus comprising;

a tubular fluid conduit having a circumferential sidewall having a first end and a second end,

first and second neck portions extending substantially perpendicular from the circumferential sidewall and being substantially parallel to each other, wherein each neck portion comprises a drain valve portion extending from the neck portion, including a drain shut-off valve and a drain port, and

first and second flow diversion devices disposed in the first and second neck portions, respectively, wherein each flow diversion device forms a first flow path between the tubular fluid conduit and the neck in a first position and a second flow path between the drain valve portion and the neck in a second position.

17. The primary-secondary piping system of claim 16, further comprising a boiler operatively connected to the primary piping loop.

18. The primary-secondary piping system of claim 17, further comprising a primary piping loop circulation pump.

19. The primary-secondary piping system of claim 18, wherein the primary piping loop circulation pump is incorporated internally within the boiler.
