Balanced Port Sense Profile for Improved Capacity Performance

摘要

A fluid regulating device includes a regulator valve having an inlet, an outlet, and a valve port disposed between the inlet and the outlet. An actuator is coupled to the regulator valve and includes a valve disc that displaces along a longitudinal axis to open and close the fluid regulating device. The valve disc includes a sealing surface disposed adjacent to an outer radial end of the valve disc, and the sealing surface is adapted to sealingly engage the valve port in the closed position. The valve disc also includes an intermediate surface disposed inward of the sealing surface, and a groove is formed in the intermediate surface. The groove extends along a groove axis extending along the intermediate surface normal to the longitudinal axis, and the groove axis is at least partially curved when viewed along the longitudinal axis.

1. A fluid regulating device, comprising:
a regulator valve having an inlet, an outlet, and a valve port disposed between the inlet and the outlet; an actuator coupled to the regulator valve and comprising a valve disc, the valve disc disposed within the regulator valve and adapted for displacement along a longitudinal axis between a closed position sealingly engaging the valve port and an open position disposed away from the valve port; the valve disc including:
a sealing surface disposed adjacent to an outer radial end of the valve disc, the sealing surface adapted to sealingly engage the valve port in the closed position;an intermediate surface disposed radially inward of the sealing surface; anda groove formed in the intermediate surface, the groove extending along a groove axis extending along the intermediate surface normal to the longitudinal axis, the groove axis being at least partially curved when viewed along the longitudinal axis.
