Multifunctional roof drain for roof drainage

Abstract

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.

Description

technical field [0001] The invention relates to a multipurpose rain bucket for roof drainage, which belongs to a device for roof drainage. Background technique [0002] Building roof rainwater drainage system is an important measure to ensure the safety of buildings. In real life, the roof often leaks due to the poor drainage of the roof rainwater drainage system or the peeling off of the waterproof material around the rainwater outlet. The main reason is that the existing rain bucket used for roof rainwater drainage has an old structure and cannot meet the requirements of new waterproof materials and construction methods. [0003] According to different drainage systems, there are gravity rainwater buckets and siphon rainwater buckets commonly used for building roof rainwater drainage. Due to the difference in the structure of the gravity rain bucket and the siphon rain bucket, manufacturers often need to be equipped with two series of various molds to produce correspondi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the technical problems that the waterproof layer of the existing rainwater bucket is easy to lift and peel off, resulting in roof leakage and easy blockage of the drain, and to provide a multi-purpose rainwater bucket that can be used for both gravity flow and siphon pressure flow. Rain bucket for roof drainage

[0006] Because the present invention adopts the above-mentioned technical solution, it solves the technical problems that the waterproof layer in the existing rainwater bucket is easy to lift and peel off, causing water leakage on the roof and easy blockage of the drain outlet.
