Abstract

A boiler loop system including a primary-secondary piping loop interface apparatus 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 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, the tubular fluid conduit being without a valve and providing a flow path without obstruction between the first end and the second end,

first and second neck portions extending substantially perpendicular from the circumferential sidewall and being substantially parallel to each other, wherein the first and second neck portions comprise first and second drain valve portions, respectively, extending from the first and second neck portions, including a drain shut-off valve and a drain port, wherein at least one of the first and second drain valve portions is oriented at an oblique angle relative to the tubular fluid conduit, 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.

2. The primary-secondary piping system of claim 1, wherein the first drain valve portion is substantially parallel to the tubular fluid conduit and the second drain valve portion is oriented at an oblique angle relative to the tubular fluid conduit.

3. The primary-secondary piping system of claim 2, wherein the second drain valve portion is oriented at angle between 15 and 75 degrees relative to the tubular fluid conduit.

4. The primary-secondary piping system of claim 3, wherein the second drain valve portion is oriented at 45 degrees relative to the tubular fluid conduit.

5. The primary-secondary piping system of claim 1, wherein the first drain valve portion extends from the first neck portion in direction away from the second neck portion and the second drain valve portion extends from the second neck portion in a direction towards the first neck portion.

6. The primary-secondary piping system of claim 1, further comprising a secondary piping loop circulation pump.

7. The primary-secondary piping system of claim 6, 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.

8. The primary-secondary piping system of claim 7, wherein the flange is independently rotatable with respect to the first or the second neck portion.

9. 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.

10. The primary secondary piping system of claim 9, wherein each of the plurality of secondary piping loops constitutes a separate heating zone.

11. The primary-secondary piping system of claim 1, wherein the primary-secondary piping loop interface apparatus is constructed as a single unit.

12. 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, the first tubular fluid conduit being without a valve and providing a flow path without obstruction between the first end and the 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, the second tubular fluid conduit being without a valve and providing a flow path without obstruction between the first end and the second end,

first and second neck portions extending substantially perpendicular from the second circumferential sidewall and being substantially parallel to each other, wherein the first and second neck portions comprise first and second drain valve portions, respectively, extending from the first and second neck portions, including a drain shut-off valve and a drain port, wherein at least one of the first and second drain valve portions is oriented at an oblique angle relative to the second tubular fluid conduit, 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.

13. The primary-secondary piping system of claim 12, wherein:

the first drain valve portion of the primary-secondary piping loop interface apparatus is substantially parallel to the second tubular fluid; and

the second drain valve portion of the primary-secondary piping loop interface apparatus is oriented at angle between 15 and 75 degrees relative to the second tubular fluid conduit.

14. The primary-secondary piping system of claim 12, further comprising a boiler operatively connected to the near boiler piping loop.

15. The primary-secondary piping system of claim 12, further comprising a near boiler piping loop circulation pump.
