Operating principle: rainwater water inlet pipe 1 is installed on the building rain-water drainage standpipe, and during rainfall, flow is Q
0Rainwater enter rainwater diffluence room 2 by rainwater water inlet pipe 1 since the action of gravity meeting by flow distribution plate 3 by float valve 13 enter the bottom rain water drainage chamber 11.The volume that stores early-stage rainwater in the rain water drainage chamber 11 constantly increases, and water level rises in the rain water drainage chamber 11, and float valve 13 turns down automatically because of ball float rises, and water level arrives design liquid level H in rain water drainage chamber 11
1The time, the normally closed floating drum valve 5 of liquid level is opened automatically because of floating drum rises, and opening degree constantly increases.Water level arrives design liquid level H in rain water drainage chamber 11
2The time, normally closed floating drum valve 21 is identical by flow with float valve 13, is Q
1And less than flow of inlet water Q
0This moment, 11 water inlets of rain water drainage chamber reached dynamic balance state with water outlet, and reservoir volume is V in the rain water drainage chamber 11
1Early-stage rainwater.Along with rainfall is carried out, the part early-stage rainwater is by rainwater discharge pipe 7 continuous dischargers, and this part early-stage rainwater volume is V
2It is V that the residue early-stage rainwater can temporarily be stored in volume
3Rainwater diffluence room 2 in, water levels can raise gradually in the rainwater diffluence room 2, when arriving overflow weir 17 height, storing the early-stage rainwater volume in the rainwater diffluence room 2 is V
3, the filter screen 16 of later stage clean rainwater above overflow weir 17 enters rainwater utilization chamber 18, flows into the rainwater utilization facility by rainwater catchment system pipe 15.A small amount of clean rainwater in rainfall latter stage enters rain water drainage chamber 11 by rainwater diffluence room 2 by float valve 13, flushing action is played in rainwater diffluence room 2, float valve 13 and rain water drainage chamber 11, this moment is because the ball float decline in the normally closed floating drum valve 21 can make normally closed floating drum valve 21 close, rainwater after the flushing slowly flows into rainwater discharge pipe 7 and discharger by the leaking port of being located on the glue lid 58, finish whole abandoned stream process, prepare next rainfall and use.If the early-stage rainwater cumulative volume is V, then V=V
1+ V
2+ V
3, promptly device is used to store the volume of early-stage rainwater for only being V
1+ V
3Determine device each several part size according to the abandoned stream amount of early-stage rainwater, can realize the automatic flow abandoning of early-stage rainwater.
