Abstract

A water pressure regulator assembly has dual union ends on a pressure reducing valve body. The water pressure regulator assembly includes a drain port with a valve member and a strainer. The union fitting ends may include check inserts to prevent backflow of water within the associated plumbing system.

Claims (48)

1 . A water pressure regulator assembly, comprising:

a valve body having a fluid passageway between a first fitting end, a second fitting end, a drain port, a bell base, and a gauge port;

a bell coupled to said bell base;

a spring positioned within said bell;

a diaphragm coupled to said spring, said diaphragm coupled to a valve stem that is positioned within a stem opening in said bell base;

a screen member positioned within said drain port, said screen member including a portion that is positioned in said fluid passageway adjacent to said first fitting end;

a first fitting coupled to said first fitting end by a union coupling;

a second fitting coupled to said second fitting end by a union coupling;

a first check valve insert positioned in said first fitting adjacent to an internal shoulder in said first fitting, said first check valve insert permitting water to flow toward said first fitting end, but not permitting water to flow from said first fitting end out of said first fitting; and

a second check valve insert positioned in said second fitting adjacent to an internal shoulder in said second fitting, said second check valve insert permitting water to flow from said second fitting end to said second fitting, but not permitting water to flow from said second fitting to said second fitting end.

2 . The water pressure regulator assembly of claim 1 , including a friction ring positioned between said bell and said bell base.

3 . The water pressure regulator assembly of claim 1 , wherein said gauge port is positioned on said valve body opposite said stem opening.

4 . The water pressure regulator assembly of claim 1 , including a fastener coupled to a spring spacer that controls said spring.

5 . The water pressure regulator assembly of claim 4 , including a handle coupled to said fastener.

6 . The water pressure regulator assembly of claim 1 , wherein said drain port includes a valve member.

7 . The water pressure regulator assembly of claim 6 , wherein said drain port includes a female pipe thread end that couples to a male pipe thread on said valve member.

8 . The water pressure regulator assembly of claim 1 , wherein said first union fitting includes an O-ring that compresses against said first fitting end.

9 . The water pressure regulator assembly of claim 1 , wherein said second union fitting includes an O-ring that compresses against said second fitting end.

10 . A water pressure regulator assembly, comprising:

a valve body having a fluid passageway between a first fitting end, a second fitting end, a drain port, and a bell base;

a bell coupled to said bell base;

a spring positioned within said bell;

a diaphragm coupled to said spring, said diaphragm coupled to a valve stem that is positioned within a stem opening in said bell base;

a screen member positioned within said drain port, said screen member including a portion that is positioned in said fluid passageway adjacent to said first fitting end;

a valve member positioned on said drain port;

a first fitting coupled to said first fitting end by a union coupling;

a second fitting coupled to said second fitting end by a union coupling;

a first check valve insert positioned in said first fitting adjacent to an internal shoulder in said first fitting, said first check valve insert permitting water to flow toward said first fitting end, but not permitting water to flow from said first fitting end out of said first fitting; and

a second check valve insert positioned in said second fitting adjacent to an internal shoulder in said second fitting, said second check valve insert permitting water to flow from said second fitting end to said second fitting, but not permitting water to flow from said second fitting to said second fitting end.

11 . The water pressure regulator assembly of claim 10 , including a friction ring positioned between said bell and said bell base.

12 . The water pressure regulator assembly of claim 10 , including a gauge port positioned on said valve body opposite said stem opening.

13 . The water pressure regulator assembly of claim 10 , including a fastener coupled to a spring spacer that controls said spring.

14 . The water pressure regulator assembly of claim 13 , including a handle coupled to said fastener.

15 . The water pressure regulator assembly of claim 10 , wherein said drain port includes a female pipe thread end that couples to a male pipe thread on said valve member.

16 . The water pressure regulator assembly of claim 10 , wherein said first union fitting includes an O-ring that compresses against said first fitting end.

17 . A water pressure regulator valve assembly, comprising:

a valve body having a fluid passageway between a first fitting end, a second fitting end, a drain port, and a bell base;

a bell coupled to said bell base;

a spring positioned within said bell;

a diaphragm coupled to said spring, said diaphragm coupled to a valve stem that is positioned within a stem opening in said bell base;

a screen member positioned within said drain port, said screen member including a portion that is positioned in said fluid passageway adjacent to said first fitting end;

a first fitting coupled to said first fitting end by a union coupling;

a second fitting coupled to said second fitting end by a union coupling;

a first check valve insert positioned in said first fitting adjacent to an internal shoulder in said first fitting, said first check valve insert permitting water to flow toward said first fitting end, but not permitting water to flow from said first fitting end out of said first fitting; and

a second check valve insert positioned in said second fitting adjacent to an internal shoulder in said second fitting, said second check valve insert permitting water to flow from said second fitting end to said second fitting, but not permitting water to flow from said second fitting to said second fitting end.

18 . The water pressure regulator valve assembly of claim 17 , including a friction ring positioned between said bell and said bell base.

19 . The water pressure regulator valve assembly of claim 17 , including a gauge port positioned on said valve body opposite said stem opening.

20 . The water pressure regulator valve assembly of claim 17 , wherein said drain port includes a valve member.
