Abstract

A primary/secondary loop adapter comprising a valve body having a first primary loop port, a second primary loop port, a first secondary loop port and a second secondary loop port is provided. The secondary loop ports are disposed at respective ends or a linear secondary loop portion of the valve body. A primary loop portion of the valve body is formed by a pair of closely spaced tees extending from the secondary loop portion. At least one main valve portion is disposed in a first one of the tees. A drain/venting valve portion may extend from one or more of the main valve portions. One or both of the primary loop ports may include a flange for connecting to an apparatus in the primary loop.

Claims

1. A primary/secondary loop adapter comprising:

a valve body having a first primary loop port, a second primary loop port, a first secondary loop port and a second secondary loop port;

the secondary loop ports disposed at respective ends of a linear secondary loop portion of the valve body;

a primary loop portion of the valve body formed by a pair of closely spaced tees extending from the secondary loop portion; and

at least one main valve portion disposed in at least one of the tees between the secondary loop portion and a primary loop port.

2. The primary/secondary loop adapter of claim 1, comprising:

a portion of the secondary loop portion between the tees shared with the primary loop portion.

3. The primary/secondary loop adapter of claim 1, wherein flow in a primary loop and a secondary loop are hydraulically separated.

4. The primary/secondary loop adapter of claim 1, comprising:

a drain/venting valve portion extending from one or more of the at least one main valve portions.

5. The primary/secondary loop adapter of claim 1, comprising:

a main actuator extending from the valve body in said main valve portion and enabling a first and second position of the main valve portion; and

a purge valve actuator extending from the drain/venting valve portion and enabling a first and second position of the drain/venting valve portion.

6. The primary/secondary loop adapter of claim 5, comprising:

a main flow diversion device connected to a main handle via the main actuator; and

a purge valve flow diversion device connected to a purge valve handle via the purge valve actuator.

7. The primary/secondary loop adapter of claim 6, comprising:

said main flow diversion device including a main ball portion having a through hole extending centrally there-through and having a blind hole extending orthogonally to said through hole from a center of said main ball portion, said main ball portion being rotatable about an axis through said center and orthogonal to a plane of said through hole and said blind hole.

8. The primary/secondary loop adapter of claim 6, comprising:

said purge valve flow diversion device comprising a second ball portion having a through hole extending there-through and being rotatable about a central axis normal to the plane of said through hole.

9. The primary/secondary loop adapter of claim 1, comprising:

a flange configured on at least one of said primary loop ports, said flange adapted for connecting directly to an apparatus in the primary loop.

10. The primary/secondary loop adapter of claim 9, wherein said apparatus in the primary loop comprises a pump.

11. A primary/secondary loop adapter comprising:

a valve body having a first primary loop port, a second primary loop port, a first secondary loop port and a second secondary loop port;

the secondary loop ports disposed at respective ends of a linear secondary loop portion of the valve body;

a primary loop portion of the valve body formed by a pair of closely spaced tees extending from the secondary loop portion;

at least one main valve portion disposed in at least one of the tees between the secondary loop portion and a primary loop port; and

a flange configured on at least one of said primary loop ports, said flange adapted for connecting directly to an apparatus in the primary loop.
