Independent Claim
320 words
A diverter valve for underground installations operating at relatively low pressures for controlling the flow of effluent from a septic tank to a plurality of leach beds, having a valve body, a valve plug, and a retainer cap for the valve plug, comprising; a thick-walled valve body of cast urethane defining a vertically disposed cylindrical central valve chamber having an inlet port and a plurality of spaced outlet ports, centrally disposed circular openings in the top and bottom walls of the valve body, the walls of which provide bearing surfaces for a tapered valve plug, integrally cast downwardly tapered and uniformly spaced heavy ribs extending from the top to the bottom walls of the valve body dividing the central chamber into a plurality of substantially uniform smaller chambers communicating directly with the central chamber, a valve plug comprising a unitary urethane casting having circular top and bottom sections rotatively mounted for sealing contact with the upper and lower bearing surfaces of the valve body, the valve body having a cut-away center section providing a passageway for alternately connecting the inlet port with one of the outlet ports, the remaining center portion of the valve plug being in slidable and sealing contact with at least two of the ribs to close at least one of the outlets while one outlet remains open, the valve plug having an integrally cast shaft at the upper end thereof, said shaft extending through the upper central opening in the top of the valve body and through an opening in the retainer cap, the upper end of the shaft having an upwardly extending projection adapted to receive a slotted tool to actuate the plug from ground level, and a circular groove in the top surface of the valve body adapted to receive a section of pipe, closed with a cap provided with a screw-threaded plug to afford access to the valve plug for operating the same.

A diverter valve for underground installations operating at relatively low pressures for controlling the flow of effluent from a septic tank to a plurality of leach beds, having a valve body, a valve plug, and a retainer cap for the valve plug, comprising; a thick-walled valve body of cast urethane defining a vertically disposed cylindrical central valve chamber having an inlet port and a plurality of spaced outlet ports, centrally disposed circular openings in the top and bottom walls of the valve body, the walls of which provide bearing surfaces for a tapered valve plug, integrally cast downwardly tapered and uniformly spaced heavy ribs extending from the top to the bottom walls of the valve body dividing the central chamber into a plurality of substantially uniform smaller chambers communicating directly with the central chamber, a valve plug comprising a unitary urethane casting having circular top and bottom sections rotatively mounted for sealing contact with the upper and lower bearing surfaces of the valve body, the valve body having a cut-away center section providing a passageway for alternately connecting the inlet port with one of the outlet ports, the remaining center portion of the valve plug being in slidable and sealing contact with at least two of the ribs to close at least one of the outlets while one outlet remains open, the valve plug having an integrally cast shaft at the upper end thereof, said shaft extending through the upper central opening in the top of the valve body and through an opening in the retainer cap, the upper end of the shaft having an upwardly extending projection adapted to receive a slotted tool to actuate the plug from ground level, and a circular groove in the top surface of the valve body adapted to receive a section of pipe, closed with a cap provided with a screw-threaded plug to afford access to the valve plug for operating the same.
Claim 3
Dependent Claim
16 words
A diverter valve as defined in claim 1, having an inlet port and two outlet ports.
Claim 4
Dependent Claim
21 words
A diverter valve as defined in claim 2, in which the inlet port and the outlet ports are spaced 120° apart.
Claim 5
Dependent Claim
65 words
A diverter valve as defined in claim 1, in which the shaft of the upper end of the valve plug has a cast knob cooperating with a groove in the lower surface of the cap limiting the rotation of the valve plug and providing proper alignment of the passageway in the valve plug with the inlet port and an outlet port in the valve body.
Claim 6
Dependent Claim
42 words
A diverter valve as defined in claim 4, in which indicia are cast in the valve body to designate the inlet port and the outlet ports, and on the upper end of the valve plug to indicate the position of said plug.
