Abstract
Abstract A fluid flow control valve having a valve body in which is formed a vertical elongated chamber. The valve body is provided with an inlet passage and an outlet passage, and with a stationary annular seal mounted around the inner end of each of said passages. A rotatable valve is operatively mounted between said annular seals. The rotatable valve is provided with means for releasably retaining the valve in a locked position when it is rotated to the closed position. The rotatable valve has a pair of chambers formed therein, with one of said chambers comprising an inlet chamber having an inlet port communicating with said inlet passage and a downwardly opening outlet port communicating with the lower end of said valve body chamber, and the other of said pair of chambers comprising an outlet chamber having an upwardly opening inlet port communicating with said valve body chamber and an outlet port communicating with said outlet passage, whereby fluid entering said inlet passage will pass through said rotatable valve inlet chamber and down into the lower end of said valve body chamber and thence upwardly around said rotatable valve and into said rotatable valve outlet chamber and into said outlet passage. The valve includes means mounted in the lower end of the valve body chamber for rotating the rotatable valve between open and closed positions. The lower end of the elongated valve body chamber is adapted to function as a sediment and condensate collection chamber. A valve means is operatively mounted in the valve body for regulating the flow of fluid from the upper end of the valve body chamber into the rotatable valve outlet chamber.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
341 words
A fluid flow control valve comprising: a. a valve body having a valve chamber therein; b. an inlet passage communicating with said valve body valve chamber and an outlet passage communicating with said valve body valve chamber at a point diametrically opposite to the inlet passage; c. an annular seal around each of said passages and being disposed at the point where each of said passages communicates with said valve body valve chamber; d. a rotatable valve in said valve chamber having an upper end and a lower end and being operatively seated between and against said annular seals; e. said rotatable valve being rotatable between a first position and a second position and having a pair of chambers formed therein with one of said chambers comprising an inlet chamber having a sidewardly facing inlet port communicating with said inlet passage when the rotatable valve is in a first position and a downwardly facing outlet port communicating with said valve body valve chamber through the lower end of the valve, and the other of said pair of chambers comprising an outlet chamber having an upwardly facing inlet port communicating with said valve body valve chamber through the upper end of the valve and a sidewardly facing outlet port communicating with said outlet passage when the valve is in a first position, whereby fluid entering said inlet passage will pass directly into and through said rotatable valve inlet chamber and downwardly into said valve body valve chamber and thence upwardly through only said valve chamber and around the outside of said valve and thence downwardly into said rotatable valve outlet chamber and directly into said outlet passage; and, f. means releasably connected to said rotatable valve for rotating said rotatable valve to a first position to permit said flow of fluid from said inlet passage and through said rotatable valve and only said valve chamber to said outlet passage, and to a second position whereby the flow of fluid between the inlet passage and outlet passage is blocked by said rotatable valve.
Claim 2
Dependent Claim
341 words
A fluid flow control valve comprising: a. a valve body having a valve chamber therein; b. an inlet passage communicating with said valve body valve chamber and an outlet passage communicating with said valve body valve chamber at a point diametrically opposite to the inlet passage; c. an annular seal around each of said passages and being disposed at the point where each of said passages communicates with said valve body valve chamber; d. a rotatable valve in said valve chamber having an upper end and a lower end and being operatively seated between and against said annular seals; e. said rotatable valve being rotatable between a first position and a second position and having a pair of chambers formed therein with one of said chambers comprising an inlet chamber having a sidewardly facing inlet port communicating with said inlet passage when the rotatable valve is in a first position and a downwardly facing outlet port communicating with said valve body valve chamber through the lower end of the valve, and the other of said pair of chambers comprising an outlet chamber having an upwardly facing inlet port communicating with said valve body valve chamber through the upper end of the valve and a sidewardly facing outlet port communicating with said outlet passage when the valve is in a first position, whereby fluid entering said inlet passage will pass directly into and through said rotatable valve inlet chamber and downwardly into said valve body valve chamber and thence upwardly through only said valve chamber and around the outside of said valve and thence downwardly into said rotatable valve outlet chamber and directly into said outlet passage; and, f. means releasably connected to said rotatable valve for rotating said rotatable valve to a first position to permit said flow of fluid from said inlet passage and through said rotatable valve and only said valve chamber to said outlet passage, and to a second position whereby the flow of fluid between the inlet passage and outlet passage is blocked by said rotatable valve.
