Flow diversion means

Claim 2

Flow diversion means for a sump or the like adapted to collect separately, as run-off liquid from a surface; various liquids including a process liquid from a supply pipe, said flow diversion means including first and second outlet means from said sump and an outlet valve assembly co-operating operatively therewith and operable to place either said first or said second outlet means in liquid communication with said sump, said outlet valve assembly being normally biased to maintain said first outlet means in said closed condition, there being further provided control means connected operatively to said supply pipe whereby upon supply of liquid from said supply pipe, said outlet valve assembly operates automatically to close said second outlet means and simultaneously open said first outlet means so that process liquid entering said sump from said supply pipe will be diverted through said first outlet means.

Claim 3

Flow diversion means according to claim 1, wherein said second outlet means is spaced above said first outlet means.

Claim 4

Flow diversion means according to claim 2, wherein said surface comprises an open floor for collecting storm water run-off from said floor as well as process liquids discharged onto said floor, and wherein said second outlet means is adapted for connection to storm water mains and said first outlet means is adapted for connection to a waste treatment system.

Claim 5

Flow diversion means according to claim 2, wherein said control means is operable by fluid pressure and wherein said operative connection to said supply pipe includes a control hose communicating with said supply pipe and said control means in such manner that pressure build-up in said supply pipe is transmitted to said outlet valve assembly to actuate same.

Claim 6

Flow diversion means according to claim 4, wherein said supply pipe includes a valve for controlling flow therethrough and is further provided with flow restricting means between its outlet and the valve controlling flow therethrough and wherein said control hose is connected operatively to said supply pipe at a position intermediate said valve controlling flow through said supply pipe and said flow restricting means.

Claim 7

Flow diversion means according to claim 4, wherein said control means comprises a fluid actuated telescopic ram assembly.

Claim 8

Flow diversion means according to claim 6, wherein said telescopic ram assembly comprises a pair of rams each connected to a respective valve member adapted to cooperate with the respective outlet means.

Claim 9

Flow diversion means according to claim 4, wherein said first and second outlet means are disposed substantially at right angles to one another and said outlet valve assembly comprises a pair of valve members adapted for operative cooperation with a respective outlet means and supported on a valve frame assembly adapted for pivoted connecting to said sump in such manner that either valve member may be moved pivotally, alternately into or out of engagement with the respective outlet means and wherein said control means includes a bellows connected operatively to said control hose and adapted upon expansion to pivot said frame.

Claim 10

Flow diversion means according to claim 8, wherein said first outlet means comprises a valve seat adapted to be arranged at the bottom of said sump about a vertical axis and said second outlet means comprises a valve seat adapted to be arranged at the side of said sump about a horizontally extending axis.

Claim 13

A sump assembly having an inlet arranged to collect separately a plurality of liquids each emanating from a respective liquid source and to discharge the so-collected liquid through a respective one of a plurality of outlet means provided therein, said sump assembly having an outlet valve assembly adapted to cooperate operatively with said outlet means so as to place the respective outlet means in liquid communication with said sump for outflow of collected liquid therethrough, and control means adapted to monitor each liquid source to automatically actuate said outlet valve assembly to open the respective outlet means for outflow of the collected liquid emanating from the respective monitored source.

Claim 14

A sump assembly having an inlet arranged to collect separately a plurality of liquids each emanating from a respective liquid source and to discharge the so-collected liquid through a respective one of a plurality of outlet means provided therein, said sump assembly having an outlet valve assembly adapted to cooperate operatively with said outlet means so as to place the respective outlet means in liquid communication with said sump for outflow of collected liquid therethrough, and control means adapted to monitor each liquid source to automatically actuate said outlet valve assembly to open the respective outlet means for outflow of the collected liquid emanating from the respective monitored source.

Claim 15

Flow diversion means for a sump or the like adapted to collect separately, as run-off liquid from a surface, polluted processed liquid or clean liquid each emanating from a different source, said flow diversion means including first and second outlet means from said sump and an outlet valve assembly cooperating operatively therewith and operable in a first mode of operation in which said first outlet means is open for outflow of said clean liquid with said second outlet means closed, and in a second mode of operation in which said second outlet means is open for outflow of said polluted processed liquid with said first outlet means closed, and there being further provided control means adapted to monitor the polluted processed liquid source to automatically actuate said outlet valve assembly to operate in the respective mode of operation for outflow of the collected liquid emanating from respective sources through the respective outlet means.

Claim 16

Flow diversion means for a sump or the like adapted to collect separately, as run-off liquid from a surface, polluted processed liquid or clean liquid each emanating from a different source, said flow diversion means including first and second outlet means from said sump and an outlet valve assembly cooperating operatively therewith and operable in a first mode of operation in which said first outlet means is open for outflow of said clean liquid with said second outlet means closed, and in a second mode of operation in which said second outlet means is open for outflow of said polluted processed liquid with said first outlet means closed, and there being further provided control means adapted to monitor the polluted processed liquid source to automatically actuate said outlet valve assembly to operate in the respective mode of operation for outflow of the collected liquid emanating from respective sources through the respective outlet means.

Claim 17

Flow diversion means according to claim 12, wherein said outlet valve assembly further comprises means for biasing said assembly for operation in said first mode of operation.
