Abstract:
A pump intake pressure control apparatus includes an intake conduit joining a pump to either a pressurized or unpressurized liquid source, a wide-range flow controller configured to control the flow of liquid through the intake conduit, pressure sensors for detecting the pressure of the liquid in the intake conduit upstream and downstream of the flow controller, and an electronic master controller programmed to receive input from the pressure sensors and to actuate the wide-range flow controller to maintain the pressure downstream of the wide-range flow controller at or below a predetermined desired value. In one embodiment of the invention, the wide-range flow controller is a branched portion of the intake conduit having a valve in each branch. In another embodiment of the invention, the flow controller is a gate valve having a stationary triangular blocking member projecting into the passage between the inlet and outlet ports of the valve.

Claim (Index 5):
The intake pressure control system according to  claim 1 , wherein the wide-range flow controller comprises:\n a valve housing having a distal end; a valve seat formed in the distal end of the valve housing; a gate mounted for reciprocation within the valve housing, the gate having a distal surface, a triangular blocking member supported in the distal end of the valve housing, the triangular blocking member having a base extending parallel to the valve seat and an upper vertex abutting a side wall of the valve housing; and an actuator configured to move the gate from a fully closed position against the valve seat to a fully open position above the upper vertex of the triangular member; wherein the gate, the triangular blocking member, and the valve housing define a triangular flow passage allowing flow to pass through the flow controller at a low flow rate when the distal surface of the gate is positioned between the valve seat and the upper vertex of the triangular blocking member; and wherein the gate, the triangular blocking member, and the valve housing define a trapezoidal flow passage allowing flow to pass through the flow controller at a high flow rate when the distal surface of the gate is positioned above the upper vertex of the triangular blocking member.
