Description

A kind of flat-head type roof Quick drainage device

Technical field

The utility model belongs to roof drainage equipment technical field, and in particular to a kind of flat-head type roof Quick drainage fills It sets.

Background technology

Siphonic drainage system is to realize gas-water separation using the special rainwater funnel in roof.Due to gravity when beginning, Make to generate vacuum in storm sewer, when the water in pipe is in pressure stream mode, forms siphonage, constantly drained, finally Reach flowing full state in rain pipe.During the rainfall, since continuously siphonage, whole system are able to quick drain Rainwater on roof.

As the Chinese utility model patent of Patent No. CN201621023959.8 discloses a kind of quick row in workshop top Water installations, the drainage arrangement include roof drain, drainpipe, ponding ditch, and ponding ditch is arranged in the top in house, the bottom surface of ponding ditch Ponding ditch length direction is provided with slope, the minimum point in ponding ditch is arranged in roof drain, and the lower end of roof drain connects drainpipe, Roof drain includes block, bucket body, and the outer diameter of bucket body is more than the outer diameter of drainpipe, and the opening of bucket body is provided with boss, boss Outer diameter is more than the outer diameter of bucket body, and bucket body, boss are absorbed in building interior, and block is arranged above boss, the top surface and side of block It is both provided with leakage hole, the leakage hole of cap side faces is less than the bottom surface nadir of ponding ditch.

The drainage arrangement is arranged by the way that ponding ditch is arranged at the top of house, and by roof drain in ponding ditch minimum point, to carry High drainage efficiency.

Drainpipe is usually made of being connected to VERTICAL TUBE by horizontal tube, and the communicating position of horizontal tube and VERTICAL TUBE can be formed Corner negative pressuren zone, siphon is to be accelerated to decline by gravity at the corner negative pressuren zone by rainwater, lead to negative pressure, to atmospheric pressure Rainwater can be promoted constantly to enter drainpipe.Siphonic drainage system can realize that the premise of Quick drainage is gas-water separation, though So when rainwater flow is larger, roof drain can realize this purpose, but less (with rainfall initial period or knot in rainwater flow The beam stage) when, air still easily enters in drainpipe, and siphon is caused to fail, and drainage efficiency reduces.

Utility model content
