Multifunctional roof drain for roof drainage
The invention relates to a multifunctional roof drain for roof drainage and belongs to a device for roof drainage. The roof drain mainly aims to solve the technical problems that according to an existing roof drain, a waterproof layer is prone to turning up and peeling off, and accordingly water leakage happens to a roof and a drainage opening is blocked easily. According to the technical scheme, the multifunctional roof drain for roof drainage comprises a drain body, a pressing plate, a drain cap and a tail pipe, and further comprises an anti-vortex rectifier which is composed of a ring, a disc and multiple flow guide pieces, wherein the ring is arranged on the upper portion of the anti-vortex rectifier, the disc is arranged in the middle of the anti-vortex rectifier, the flow guide pieces are vertically arranged around the disc, and the tops of the flow guide pieces are connected with the bottom face of the ring. The roof drain has the advantages that the structure and the size are uniform, the roof drain can be produced and stored on a large scale, a construction method is consistent, engineering quality is guaranteed, the roof drain has the dual functions of a gravity type roof drain and a siphon pressure flow roof drain, interchangeability of parts and accessories is good, and the roof drain is convenient to maintain and replace.
