Abstract
Abstract Fluid pump-effluent is completely and instantaneously routed to one of two conduits in a system which includes a vertically extending main line, passing through a special valve, and a secondary line passing laterally from said valve. The valve includes a closure member pivotable around a pivot line through an arch which is upstream with respect to said pivot line, and generally below said pivot line, the pivot line being positioned at one side of said main steam above the secondary line, the closure member being seatable on both primary line, and secondary line, valve seats.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
213 words
A valve comprising: a casing including an inlet and a pair of upwardly directed outlets, and including a vertical conduit connecting the inlet with a first of the upwardly directed outlets and an upwardly and outwardly extending conduit connecting the vertical conduit with the second outlet, annular valve seats at said first and said second outlets; a closure member adapted to alternatively engage said valve seats to selectively close said first or said second outlet; a shaft journaled in said housing for pivotally supporting the closure member about a horizontal axis located at the juncture of said conduits; said shaft extending through said casing to an external portion thereof; a handle-indicator fixed to said external portion of said shaft; said shaft being free swinging and said closure member being heavy enough to swing to a position below said shaft when there is no flow of fluid to said valve at which position said first outlet is substantially open and said second outlet is partially closed whereby pressure exerted by upwardly flowing fluid within said valve casing moves said closure member to close said second outlet and to permit flow only through said first outlet, said handle-indicator being manipulatable to move said closure member to open said second outlet and close said first outlet.

A valve comprising: a casing including an inlet and a pair of upwardly directed outlets, and including a vertical conduit connecting the inlet with a first of the upwardly directed outlets and an upwardly and outwardly extending conduit connecting the vertical conduit with the second outlet, annular valve seats at said first and said second outlets; a closure member adapted to alternatively engage said valve seats to selectively close said first or said second outlet; a shaft journaled in said housing for pivotally supporting the closure member about a horizontal axis located at the juncture of said conduits; said shaft extending through said casing to an external portion thereof; a handle-indicator fixed to said external portion of said shaft; said shaft being free swinging and said closure member being heavy enough to swing to a position below said shaft when there is no flow of fluid to said valve at which position said first outlet is substantially open and said second outlet is partially closed whereby pressure exerted by upwardly flowing fluid within said valve casing moves said closure member to close said second outlet and to permit flow only through said first outlet, said handle-indicator being manipulatable to move said closure member to open said second outlet and close said first outlet.
