Fluid Regulator Having Pressure Registration Flow Modifier

A fluid regulating device, comprising:

• a valve body having an inlet, an outlet, and a valve port, the valve body defining a flow path extending from adjacent the inlet, through the valve port, and exiting through the outlet along an outlet axis;
• a control element shiftably disposed within the valve body, the control element displaceable relative to the valve port to control the flow of a fluid between the inlet and the outlet;
• a control assembly comprising a valve actuator, the control assembly operatively coupled to the control element, the control assembly including a diaphragm disposed adjacent a diaphragm chamber;
• a sense tube having a first end, a second end, and an intermediate portion, the first end positioned to provide flow communication with the diaphragm chamber of the control assembly, the second end disposed adjacent a distal portion of the outlet and the intermediate portion disposed adjacent an intermediate portion of the outlet;
• a flow interrupter disposed in the flow path adjacent the intermediate portion of the sense tube;
• and
• a flared portion disposed in the flow path adjacent the second end and downstream of the flow interrupter.

A method of sensing output pressure in a fluid regulating device, the method comprising the steps of:

• providing a valve body having an inlet, an outlet, and a valve port, the valve body defining a flow path extending from adjacent the inlet, through the valve port, and exiting through the outlet along an outlet axis;
• providing a control element shiftably disposed within the valve body, the control element displaceable relative to the valve port to control the flow of a fluid between the inlet and the outlet;
• providing a control assembly comprising a valve actuator, the control assembly operatively coupled to the control element, the control assembly including a diaphragm disposed adjacent a diaphragm chamber;
• providing a sense tube having a first end, a second end, and an intermediate portion;
• positioning the first end to provide flow communication with the diaphragm chamber of the control assembly;
• positioning the second end adjacent a distal portion of the outlet of the valve body;
• positioning a flow interrupter along the flow path adjacent an intermediate portion of the sense tube;
• and
• providing a flared portion on the sense tube, and positioning the flared portion adjacent the second end of the sense tube and downstream of the flow interrupter.
