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.
Claims20
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.

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.
