Fluid control valve having discrete flow channels arranged to equalize the velocity of fluid at the perimeter of the valve port
First Claim
1. A fluid flow control valve, comprising:
- a valve body defining an inlet, an outlet, and a valve port between the inlet and the outlet;
a plurality of discrete flow channels non-removably formed in the valve body, the plurality of discrete flow channels extending between the inlet and the valve port to distribute fluid flowing through the inlet to the valve port, the plurality of discrete flow channels comprising;
one or more first flow channels arranged to direct a first amount of the fluid flowing through the inlet to a front portion of the valve port;
one or more second channels arranged to direct a second amount of the fluid flowing through the inlet to a rear portion of the valve port opposite the front portion; and
one or more third channels arranged to direct a third amount of the fluid flowing through the inlet to one or both side portions of the valve port extending between the front and rear portions; and
a trim assembly arranged in the valve body, the trim assembly comprising a valve seat and a seat retainer, the valve seat defining the valve port, the seat retainer seated against the valve seat to retain the valve seat in position, and the seat retainer comprising a plurality of windows sized and shaped to correspond to a cross-section of the plurality of discrete flow channels.

Abstract
A valve body and a control valve including such a valve body, the valve body including an inlet, an outlet, and a valve port defined therebetween. The valve body also includes a plurality of discrete flow channels that extend between the inlet and the valve port to distribute fluid flow to the valve port in a manner that equalizes the velocity of fluid at the perimeter of the valve port. The plurality of discrete flow channels includes (i) one or more first flow channels arranged to direct a first amount of the fluid flow to a front portion of the valve port, (ii) one or more second flow channels arranged to direct a second amount of the fluid flow to a rear portion of the valve port, and (iii) one or more third flow channels arranged to direct a third amount of the fluid flow to one or both side portions of the valve port.
