Externally adjustable flow management valve assembly and system
Disclosed is a system and valve assembly that can be used to promote the laminar flow of a variety of fluids and gases. In one embodiment, the valve assembly can be used to remove entrained water bubbles from a water supply. This, in turn, increases the density of water running through an associated water meter. This ensures that the water meter is not inaccurately including entrained air as metered water. The result is more accurate water readings and reduced utility bills. The assembly can be externally adjusted using an adjustment tool so as to increase or decrease the tension on an interior spring which, in turn, increases or decreases the rate at which the interior block oscillates.
1. A valve assembly having an inlet and an outlet, the valve assembly adapted to increase the accuracy of an upstream meter, the valve assembly comprising:
a cylindrical valve housing nested within an upper housing and lower housing, the valve housing having a housing valve inlet and a housing valve outlet, a tapered valve seat positioned adjacent to the housing valve inlet, a plurality of adjustment bores, and a series of housing threads on an outside face of the valve housing;
a valve disc positioned within the valve housing, the disc being tapered along its length, wherein the taper of the valve seat matches the taper of the valve disc, the valve disc having a seated orientation wherein it is in contact with the valve seat and an unseated orientation wherein the valve disc is spaced from the valve seat;
a valve shaft having a forward end, a rearward end, and an intermediate extent therebetween, the valve shaft further comprising a retainer having a shoulder on the rearward end extending perpendicularly from a surface of the retainer and having an axial passage, the valve shaft slidably positioned within the axial passage;
a coil spring positioned about the intermediate extent of the valve shaft, the coil spring having a first end in contact with the shoulder of the retainer, a second end of the coil spring contacting the valve disc, whereby the spring tension is varied depending upon the position of the housing threads which may be raised or lowered using an adjustment tool, the adjustment tool comprising a grip having a proximal and a distal end wherein the distal end terminates in a curved prong having an extension which protrudes from the curved prong.
2. The valve assembly of claim 1 wherein the valve assembly is used in connection with a water meter.
3. The valve assembly of claim 1 wherein the valve assembly is used in connection with a fluid meter.
4. The valve assembly of claim 1 wherein the valve assembly is used in connection with a condensate meter.
5. The valve assembly of claim 1 wherein the valve assembly is used in connection with a gas meter.
6. The valve assembly of claim 1 wherein the extension of the adjustment tool comprises a prism shape.
7. An externally adjustable valve assembly comprising:
a valve housing including an outer housing with external threads, first and second sides, a valve seat, a series of adjustment holes formed within the outer housing, a valve disc positioned within the valve housing and positioned for selective engagement with the valve seat, a spring operatively connected to the valve disc and biasing the valve disc to a closed position against the valve seat;
a first enclosure positioned over the first side of the valve housing, the first enclosure including internal threads, the internal threads of the first enclosure mating with the external threads of the valve housing;
a second enclosure positioned over the second side of the valve housing and coupled to the first enclosure, the second enclosure including a plurality of windows around a periphery of the second enclosure, the adjustment holes being accessible through the plurality of windows;
whereby the adjustment holes can be used to rotate and move the valve housing relative to the first and second enclosures with the movement of the valve housing selectively adjusting the tension of the spring.
8. The externally adjustable valve assembly as described in claim 7 wherein the second enclosure includes internal threads that mate with the external threads of the valve housing.
9. The externally adjustable valve assembly as described in claim 7 wherein the plurality of windows are formed in the first enclosure.
