Abstract

A control valve features a first housing and a second housing. The first housing includes a first inlet port having a first inlet port orifice member with a first inlet port orifice size configured to provide a first inlet fluid with a first inlet volumetric flow rate, the first inlet port orifice member being detachably coupled inside the first inlet port; includes a second inlet port having a second inlet port orifice member with a second inlet port orifice size configured to provide a second inlet fluid with a second inlet volumetric flow rate, the second inlet port orifice member being detachably coupled inside the second inlet port; and includes a first housing rim configured to extend from the first fixed inlet and the second fixed inlet. The second housing includes a second housing rim coupled to the first housing rim and configured to form a mixture chamber to mix the first inlet fluid received from the first fixed inlet orifice and the second inlet fluid received from the second fixed inlet orifice and provide a mixture chamber fluid; and an outlet port having an outlet port orifice with an outlet port orifice size configured to provide the mixture chamber fluid as an outlet port fluid having an outlet volumetric flow rate. The outlet port fluid has a mixture ratio of the first inlet fluid and the second inlet fluid for a particular application that depends on dimensions of the first inlet port orifice size, the second inlet port orifice size and the outlet port orifice size.

First claim

What we claim is:

1. A control valve comprising:
a first housing including a first inlet port having a first inlet port orifice member configured with a first inlet port orifice with a first inlet port orifice size to provide a first inlet fluid with a first inlet volumetric flow rate, including a second inlet port having a second inlet port orifice member configured with a second inlet port orifice with a second inlet port orifice size to provide a second inlet fluid with a second inlet volumetric flow rate, and including a first housing rim configured to extend from the first inlet port and the second inlet port; and
a second housing having a second housing rim configured to extend from the second housing, the second housing rim being coupled to the first housing rim and forming a mixture chamber to mix the first inlet fluid received from the first fixed inlet orifice and the second inlet fluid received from the second fixed inlet orifice and provide a mixture chamber fluid, and also including an outlet port orifice member configured with an outlet port orifice having an outlet port orifice size to provide the mixture chamber fluid as an outlet port fluid having an outlet volumetric flow rate, the outlet port fluid having a mixture ratio of the first inlet fluid and the second inlet fluid that depends on dimensions of the first inlet port orifice size, the second inlet port orifice size and the outlet port orifice size.

2. A control valve according to claim 1 , wherein
the first inlet port orifice member is detachably coupled inside the first inlet port; or
the second inlet port orifice member is detachably coupled inside the second inlet port; or
the first inlet port orifice member is detachably coupled inside the first inlet port and the second inlet port orifice member is detachably coupled inside the second inlet port.

3. A control valve according to claim 1 , wherein
the first inlet port orifice member is integrated into the first housing; or
the second inlet port orifice member is integrated into the first housing; or
both the first inlet port orifice member is integrated into the first housing and the second inlet port orifice member is integrated into the first housing.

4. A control valve according to claim 1 , wherein the outlet port orifice member is integrated into, or detachably coupled to, the second housing.

5. A control valve according to claim 1 , wherein
the control valve comprises a first check valve and a second check valve;
the first inlet port is configured to receive the first check valve that allows the first inlet fluid to pass from the first inlet port, through the first fixed inlet orifice and to the mixture chamber and prevents backflow from the mixture chamber back to the first inlet port; and
the second inlet port is configured to receive the second check valve that allows the second inlet fluid to pass from the second inlet port, through the second fixed inlet orifice and to the mixture chamber and prevents backflow from the mixture chamber back to the second inlet port.

6. A control valve according to claim 1 , wherein
the control valve comprises an O-ring; and
either the first housing rim or the second housing rim includes a groove configured to receive the O-ring in order to seal the first housing rim of the first housing and the second housing rim of the second housing.

7. A control valve according to claim 1 , wherein the first inlet port orifice member and the second inlet port orifice member are replaceable with a different first inlet port orifice member having a different first inlet port orifice size and with a different second inlet port orifice member having a different second inlet port orifice size to achieve a different desired mixture ratio of the first inlet fluid and the second inlet fluid for a different application.

8. A control valve according to claim 1 , wherein
the first inlet port has a first inner channel with a first threaded inner channel surface with threads configured therein; and
the first inlet port orifice member has a first threaded outer surface with corresponding first threads for detachably coupling to the first threads on the first threaded inner channel surface inside the first inlet port.

9. A control valve according to claim 1 , wherein
the second inlet port has a second inner channel with a second threaded inner channel with second threads configured therein; and
the second inlet port orifice member has a second threaded outer surface with corresponding second threads for detachably coupling to the second threads on the second threaded inner channel surface of the second inlet port.

10. A control valve according to claim 1 , wherein
the first inlet fluid is a gas;
the second inlet fluid is a liquid; and
the outlet port fluid is a gas infused liquid.

11. A control valve according to claim 1 , wherein
the first inlet fluid is a first gas;
the second inlet fluid is a second gas; and
the outlet port fluid is a gas mixture having the first gas and the second gas.

12. A control valve according to claim 1 , wherein
the first inlet fluid is a first liquid;
the second inlet fluid is a second liquid; and
the outlet port fluid is a liquid mixture having the first liquid and the second liquid.

13. A control valve according to claim 1 , wherein
each inlet port is coupled to a respective fluid storage container;
the outlet port is coupled to a suction pump configured to draw respective inlet fluids from the respective fluid storage container through respective inlet port orifices, into the mixture chamber for mixing the respective inlet fluids, and drawing a corresponding mixture chamber fluid as an outlet port fluid through the outlet port orifice and from the outlet port; and
the outlet port fluid has a corresponding mixture ratio of the respective inlet fluids that depends on the dimensions of the first inlet port orifice size, the second inlet port orifice size and the outlet port orifice size, as well as the suction pressure of the suction pump.
