Abstract
A proportioning system includes a cutoff valve, a three-way valve, a check valve and an eductor. The cutoff valve has a cutoff intake port and a cutoff discharge port. The cutoff valve is capable of receiving a carrier fluid from a carrier fluid source and selectively discharging the carrier fluid or inhibiting carrier fluid flow. The three-way valve is capable of receiving a first active fluid and a second active fluid and is capable of selectively discharging a selected one of the first active fluid and the second active fluid, or inhibiting flow from of both the first active fluid and the second active fluid. The eductor is capable of receiving an active fluid when the carrier fluid is passing through the eductor so as to mix the active fluid with the carrier fluid.
Claims19
A proportioning system, comprising:
- a. a cutoff valve, having a cutoff intake port and a cutoff discharge port, the cutoff valve capable of receiving a carrier fluid from a carrier fluid source and selectively discharging the carrier fluid through the cutoff discharge port, the cutoff valve also capable of inhibiting carrier fluid flow from the cutoff intake port to the cutoff discharge port;
- b. a three-way valve having a first intake port, a second intake port and a first discharge port, the three-way valve capable of receiving a first active fluid through the first intake port and a second active fluid through the second intake port and capable of selectively discharging a selected one of the first active fluid and the second active fluid through the first discharge port, the three-way valve also capable of inhibiting flow from of both the first active fluid and the second active fluid to the first discharge port;
- c. a check valve in fluid communication with the first discharge port;
- and
- d. an eductor, having an eductor intake port, an eductor suction port and an eductor discharge port, the eductor suction port in fluid communication with the check valve, the eductor intake port in fluid communication with the cutoff discharge port, the eductor capable of receiving an active fluid from the check valve through the suction port when the carrier fluid is passing from the eductor intake port to the eductor discharge port so as to mix the active fluid with the carrier fluid.
A proportioning system, comprising:
- a. a three-way valve having a first intake port, a second intake port and a first discharge port, the three-way valve capable of receiving a first active fluid through the first intake port and a second active fluid through the second intake port and capable of selectively discharging a selected one of the first active fluid and the second active fluid through the first discharge port, the three-way valve also capable of inhibiting flow from of both the first active fluid and the second active fluid to the first discharge port;
- and
- b. an eductor, having an eductor intake port, an eductor suction port and an eductor discharge port, the eductor suction port in fluid communication with the first discharge port of the three-way valve, the eductor intake port in fluid communication with a fluid source, the eductor capable of receiving an active fluid from the check valve through the suction port when the carrier fluid is passing from the eductor intake port to the eductor discharge port so as to mix the active fluid with the carrier fluid.
A method of proportioning fluids, comprising the steps of:
- a. fluidly coupling a selected one of a first active fluid source and a second active fluid source to a first discharge port;
- b. educting the selected one of the first active fluid and the second active fluid into a stream of a carrier fluid so as to cause mixing of the carrier fluid and the selected one of the first active fluid and the second active fluid, thereby forming a mixed fluid;
- and
- c. discharging the mixed fluid.
