Abstract

A valve system enables use of a standard single line faucet with a water treatment system. The valve system may include a housing having ports for receiving untreated supply water, supplying water to a water treatment system, receiving treated water from the water treatment system and supplying treated water to a dispenser. The valve system includes an automatic shutoff device that prevents water from flowing into the water treatment system when the dispensing faucet is closed and allows water to flow into the water treatment system when the faucet is open. The valve system may include a pressure relief mechanism that removes pressure from the water treatment system when the faucet is closed and a check valve for maintaining a desired amount of pressure within the valve system.

Claims

1. A valve system device for connecting a downstream fluid treatment device to a single line faucet comprising:

a housing;

a first inlet port on said housing for receiving supply fluid into the valve system;

a first outlet port on said housing in fluid communication with said first inlet port, said first outlet port for transmitting fluid out of the valve system to the downstream device;

a second inlet port on said housing for receiving fluid into the valve system from the downstream device;

a second outlet port on said housing for transmitting fluid out of the valve system to the single-line faucet; and

a shutoff valve in said housing in fluid communication with said first inlet port, said first outlet port, said second inlet port, and said second outlet port, wherein said shutoff valve is capable of being switched between an open position and a closed position, said open position allowing fluid flow through said first inlet port to said first outlet port, and through said second inlet port to said second outlet port, said closed position prohibiting fluid flow from said first inlet port to said second outlet port.

2. The valve system of claim 1 including a check valve in said housing adjacent said second inlet port.

3. The valve system of claim 2 including a pressure relief mechanism between said check valve and said second inlet port capable of reducing a first pressure within said second inlet port.

4. The valve system of claim 2 wherein said check valve is capable of allowing fluid flow from said second inlet port to said second outlet port, and prohibiting fluid flow from said second outlet port to said second inlet port.

5. The valve system of claim 1 including a plunger in said shutoff valve, said plunger capable of being switched between a first position and a second position, said first position allowing fluid flow through said first inlet port to said first outlet port, and through said second inlet port to said second outlet port, said second position preventing fluid flow from said first inlet port to said second outlet port, wherein said plunger is in said first position when a pressure differential between a first pressure within said first inlet port and a second pressure within said second outlet port is greater than a specified value.

6. The valve system of claim 1 wherein said shutoff valve includes at least one stabilizing member, said stabilizing member biasing said plunger toward said closed position.

7. The valve system of claim 1 including a switch that prohibits said shutoff valve from placement in said open position.

8. A valve system comprising:

a housing;

an untreated supply flow path extending into said housing through a first inlet and out of said housing through a first outlet;

a treated supply flow path extending into said housing through a second inlet and out of said housing through a second outlet;

a check valve within said housing, wherein said check valve prevents fluid flow from said housing through said second inlet; and

a shutoff valve within said housing capable of being switched between an open position and a closed position, said open position allowing fluid flow through said untreated supply flow path and said treated supply flow path, said closed position prohibiting fluid flow through said untreated supply flow path.

9. The valve system of claim 8 including a bypass flow path extending into said housing through said first inlet and out of said housing through a third outlet.

10. The valve system of claim 9 including a pressure relief mechanism within said housing adjacent said second inlet, wherein said pressure relief mechanism is capable of venting said supply flow path when said shutoff valve is closed.

11. The valve system of claim 8 including a flow controller that limits the amount of fluid flow through said untreated supply flow path.

12. The valve system of claim 8 wherein a pressure differential is defined between a first pressure within said first inlet and a second pressure within said second outlet, said shutoff valve switched between said open position and said closed position as a function of said pressure differential.

13. The valve system of claim 8 including a stabilizing member within said shutoff valve that biases said shutoff valve toward said closed position.

14. A water treatment system comprising:

a water supply;

a water treatment device;

an input device; and

a valve system, including a first inlet port connected to said water supply for receiving supply fluid into said valve system, a first outlet port connected to said water treatment device for transmitting fluid out of said valve system to said water treatment device, a second inlet port connected to said water treatment device for receiving fluid into said valve system from said water treatment device, a second outlet port connected to said input device for transmitting fluid out of said valve system to said input device, and a shutoff valve in fluid communication with said first inlet port, said first outlet port, said second inlet port, and said second outlet port, wherein said shutoff valve is capable of switching between an open position and a closed position, said open position allowing fluid flow from said first inlet port to said first outlet port and from said second inlet port to said second outlet port, said closed position prohibiting fluid flow from said first inlet port to said first outlet port.

15. The water treatment system of claim 14 wherein said valve system includes a check valve adjacent said second inlet port.

16. The water treatment system of claim 15 including a pressure relief mechanism between said check valve and said second inlet port and a first pressure within said second inlet port, wherein said pressure relief mechanism is capable of reducing said first pressure.

17. The water treatment system of claim 14 including a flow controller adjacent to said water treatment device that limits the amount of fluid flow into said water treatment device.

18. The water treatment system of claim 14 wherein said shutoff valve includes a plunger and at least one stabilizing member, said stabilizing member biasing said plunger toward said closed position.

19. The water treatment system of claim 14 including a first pressure within said first inlet port, a second pressure within said second outlet port, and a pressure differential between said first pressure and said second pressure, wherein said shutoff valve is switched to said open position when said pressure differential is more than a specified value and said shutoff valve is switched to said closed position when said pressure differential is less than said specified value.

20. The water treatment system of claim 14 wherein the valve system includes a switch that prohibits said shutoff valve from placement in said open position.
