Abstract

In one aspect, a fluid flow disruptor is provided. The fluid flow disruptor includes a base flange having an outer diameter and an inner diameter, the base flange configured to couple to a valve, and a cap extending from the base flange. The cap includes a proximal end coupled to the base flange about the inner diameter, a distal end, and a sidewall extending between the proximal end and the distal end. At least one aperture is formed in the sidewall, and the fluid flow disruptor is configured to direct a fluid flowing in an axial direction to flow around the cap distal end, through the at least one aperture, and through the base flange inner diameter into the valve, to thereby increase a turbulence of the fluid to decrease an axial momentum load of the fluid acting on the valve.

First claim

The invention claimed is:

1. A pressure relief valve assembly comprising:
a pressure relief valve configured to couple to a fluid line, the pressure relief valve including a nozzle having an inlet port and a sleeve coupled to the nozzle, the sleeve having an outlet port; and
a fluid flow disruptor coupled to the pressure relief valve, the fluid flow disruptor comprising:
a base flange having an outer diameter and an inner diameter, the base flange coupled to the nozzle of the pressure relief valve; and
a cap extending from the base flange, the cap comprising a proximal end coupled to the base flange about the inner diameter, a distal end, and a sidewall extending between the proximal end and the distal end, wherein at least one aperture is formed in the sidewall,
wherein the fluid flow disruptor is configured to direct a fluid flowing in an axial direction of the fluid line around the cap distal end, transverse to the axial direction through the at least one aperture, along the axial direction through the base flange inner diameter, and along the axial direction through the inlet port, to thereby increase a turbulence of the fluid to decrease an axial momentum load of the fluid acting on the valve.

2. The assembly of claim 1 , wherein the cap is cylindrical.

3. The assembly of claim 2 , wherein the cap proximal end has a first diameter and the cap distal end has a second diameter, wherein the second diameter is greater than the first diameter.

4. The assembly of claim 1 , wherein the cap distal end is flat.

5. The assembly of claim 4 , wherein the cap distal end is oriented perpendicularly to an axis of a fluid line.

6. The assembly of claim 1 , wherein the at least one aperture is rectangular.

7. The assembly of claim 1 , wherein the sidewall is oriented at an angle between the cap proximal end and the cap distal end.
