Abstract
Abstract An improved brine valve assembly for control of the brine used to regenerate ion exchange material. The brine valve assembly includes a float valve arrangement for closing and sealing the inlet port when a predetermined low level is reached in the brine tank. The float valve is positioned to float within a float cage immediately prior to its sealing of the inlet port. The level of liquid within the cage is controlled through a tube having a lower end in communication therewith and an upper end in communication with the interior of the brine tank. The elevation of the upper end is adjustable to control the amount of brine drawn during each regeneration cycle. An alternative embodiment of the invention discloses a unique float construction which uses the weight of the brine to insure a better air shut-off.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
290 words
In a brine system for regenerating ion exchange material used for water conditioning including a brine tank, having a brine well positioned therein so as to define a brine valve compartment within said well and a brine storage compartment outside said well and means associated with the lower end of said well for permitting fluid communication between said brine valve compartment and said brine storage compartment; an improved brine valve assembly for controlling the influx of refill water to said tank and the efflux of brine from said tank, comprising: a. a valve body having an internal chamber and an upwardly opening annular port; b. annular seat means concentric with said annular port; c. a vertically elongated float guide means extending above said seat means in said well; d. a float means movable along said guide in response to changes in the level of liquid in said well; e. a valve closure member means carried by said float means to close against said seat means for closing said annular port when the brine level descends to a predetermined low level in said well; f. a float cage member concentric with said float guide means and positioned immediately above said valve body, said cage having a closed lower end in fluid communication with said annular port and an open upper end for receipt of said float means therethrough; g. a tube means having a lower end in fluid communication with said lower end of said float cage member and an upper end in fluid communication with said well; and h. a conduit means having a lower end in fluid communication with said valve body for withdrawing brine from said well and directing refill water into said well through said annular port.
Claim 2
Dependent Claim
290 words
In a brine system for regenerating ion exchange material used for water conditioning including a brine tank, having a brine well positioned therein so as to define a brine valve compartment within said well and a brine storage compartment outside said well and means associated with the lower end of said well for permitting fluid communication between said brine valve compartment and said brine storage compartment; an improved brine valve assembly for controlling the influx of refill water to said tank and the efflux of brine from said tank, comprising: a. a valve body having an internal chamber and an upwardly opening annular port; b. annular seat means concentric with said annular port; c. a vertically elongated float guide means extending above said seat means in said well; d. a float means movable along said guide in response to changes in the level of liquid in said well; e. a valve closure member means carried by said float means to close against said seat means for closing said annular port when the brine level descends to a predetermined low level in said well; f. a float cage member concentric with said float guide means and positioned immediately above said valve body, said cage having a closed lower end in fluid communication with said annular port and an open upper end for receipt of said float means therethrough; g. a tube means having a lower end in fluid communication with said lower end of said float cage member and an upper end in fluid communication with said well; and h. a conduit means having a lower end in fluid communication with said valve body for withdrawing brine from said well and directing refill water into said well through said annular port.
Claim 3
Dependent Claim
37 words
The invention as defined in claim 1 wherein said tube means being of a flexible material so as to permit adjustment of the level of said upper end to control the brine draw through said valve assembly.
Claim 4
Dependent Claim
51 words
The invention as defined in claim 2 wherein said upper end of said tube means is secured to a substantially vertical stem means which is supported for vertical movement within said well, said stem means having an opening formed therein to permit the flow of brine therethrough into said tube means.
Claim 5
Dependent Claim
38 words
The invention as defined in claim 3 wherein said stem means is slidably received within a stem housing means having a viewing window associated therewith, said stem means having level indicia thereon which are viewable through said window.
Claim 6
Dependent Claim
62 words
The invention as defined in claim 1 wherein said float means having a plurality of cavities formed integral therewith and extending substantially the entire depth thereof for receipt of brinE therein, said cavities having slots removed therefrom which have lower ends extending below the level of brine within said cavities when said float means is in an up position within said well.
