Pressure relief valve for acoustic induced vibration and noise reduction

A pressure relief value (PRV), comprising:

• a nozzle configured to direct a flow of fluid from an inlet of the nozzle through an outlet of the nozzle, wherein a seat is positioned at the outlet of the nozzle;
• a disc system configured to move from a closed position to an open position based at least in part on a pressure of the fluid at the inlet of the nozzle exceeding a threshold pressure, wherein the closed position restricts the fluid from flowing from the nozzle to an outlet chamber, and wherein the open position allows the fluid to flow from the nozzle to the outlet chamber;
• a spring coupled to the disc system and configured to enable the disc system to move from the closed position to the open position based at least in part on movement of the spring due to a compressive force from a fluid exceeding a threshold force when the pressure of the fluid in the nozzle exceeds the threshold pressure;
• a stem coupled to the spring and configured to align the spring with the disc system;
• and
• an outlet chamber configured to direct flow from the nozzle through an outlet of the PRV when the disc system is in the open position, wherein the outlet chamber comprises:
• a plurality of staged plates positioned across a length of the outlet chamber, wherein each staged plate from the plurality of staged plates comprises one or more orifices from a plurality of orifices, wherein each staged plate is associated with a respective pressure drop of the fluid from a plurality of pressure drops of the fluid, wherein both a first level of acoustic induced vibration and a first level of noise associated with the plurality of pressure drops are less than a second level of acoustic induced vibration and a second level of noise, respectively, associated with a single pressure drop across the outlet chamber.

A pressure relief value (PRV), comprising:

• a nozzle configured to direct a flow of fluid from an inlet of the nozzle through an outlet of the nozzle, wherein a seat is positioned at the outlet of the nozzle;
• a disc system configured to move from a closed position to an open position based at least in part on a pressure at the inlet of the nozzle exceeding a threshold pressure, wherein at least a portion of an inner circumference of the disc system is positioned around at least a portion of an outer circumference of the nozzle, wherein the disc system is configured to restrict the fluid from flowing from the nozzle through a plurality of first orifices in a flow splitting chamber in the closed position, and wherein the disc system is configured to allow the fluid to flow from the nozzle through the plurality of first orifices in the flow splitting chamber in the open position, the disc system further comprising:
• the flow splitting chamber comprising the plurality of first orifices that are configured to split the flow of the fluid through the nozzle from a single flow to a plurality of flows when the disc system is in the open position, wherein both a first level of acoustic induced vibration and a first level of noise associated with the plurality of flows are less than a second level of acoustic induced vibration and a second level of noise, respectively, associated with the single flow;
• and
• a disc positioned within the flow splitting chamber and configured to contact the seat in the closed position and to be a threshold distance from the seat in the open position, wherein the threshold distance is based at least in part on a position of the plurality of first orifices in the flow splitting chamber;
• a spring coupled to the disc system and configured to enable the disc system to move from the closed position to the open position based at least in part on movement of the spring due to a compressive force exceeding a threshold force when the pressure in the nozzle exceeds the threshold pressure;
• a stem coupled to the spring and configured to align the spring with the disc system;
• and
• an outlet chamber configured to direct flow from the nozzle through an outlet of the PRV when the disc system is in the open position, wherein the outlet chamber comprises:
• a plurality of staged plates positioned across a length of the outlet chamber, wherein each staged plate from the plurality of staged plates comprises one or more second orifices from a plurality of second orifices, wherein each staged plate is associated with a respective pressure drop of the fluid from a plurality of pressure drops of the fluid, wherein both a third level of acoustic induced vibration and a third level of noise associated with the plurality of pressure drops are less than a fourth level of acoustic induced vibration and a fourth level of noise, respectively, associated with a single pressure drop across the outlet chamber.
