Roofing Rainwater Drainage and Collection System

Core Products Center

Roofing rainwater drainage and collection system has dual function of rainwater drainage. Following the flow pattern in the roof rainwater drain line, the system includes three systems namely gravity flow, semi-pressure flow and siphon flow. Rainwater in gravity flow system is not fully filled; rainwater in semi-pressure flow system is demonstrated via mixture of air water in pipeline; rainwater in siphon flow system is fully-filled on way. Different system should apply professional roof drain.                      

 

During raindrop, roofing runoff rainwater is converged in the gutter that enters drain pipe through rainwater of various forms. By installing rainwater sundry sewage inception, part flow arrangement or split-flow devices in the rainwater vertical drainage pipe and blow-off pipe so that it discharges rainwater to rainwater pipe network at the outset of rainfall and when rainfall runoff rainfall reaches the pre-set data, spilt-flow device would automatically turn off the split-flow pipe and the system enters rainwater collection stage with rainwater collected entering water storage pond. -www.1495.com-太阳集团游戏2138网站-33138.com太阳城集团

          

It consists of funnel, pod, effluent nozzle stub, connection pressing plate and rectifier. Pod is the roof drain used to incept leaves and other solid sundries that concurrently displays the effect of rectification; rectifier is an important component of siphon roof drain used to dredge flow, lower rotational flow and cut down air into effluent short pipe of roof drain; siphon roof drain can reach full flow status with smaller water depth before the funnel.
