Double placed type efficient syphonic roof outlet

Abstract

The invention relates to a double placed type efficient syphonic roof outlet which comprises a roof drain body. The roof drain body comprises a bucket seat and a fairwater, an inner anti-eddy assembly is arranged in the cavity, the inner anti-eddy assembly comprises a first circular sheet structure, a grating of the first circular sheet structure shifts to a first offset angle in the direction of southeast or northeast relative to a radial line; an outer anti-eddy assembly is arranged on the outside of the fairwater, the outer anti-eddy assembly comprises a second circular sheet structure, a grating of the second circular sheet structure shifts to a second offset angle in the direction of southeast or northeast with respect to the radial line; the first offset angle is less than or equal to the second offset angle. The difference between the double placed type efficient syphonic roof outlet and the existing roof drain is that the anti-eddy devices are arranged on the cavity inside the roof drain and an external cover plate, and the double place type efficient syphonic roof outlet can effectively prevent the air into the rainwater system to affect the formation of the siphon by the cooperation of the first offset angle and the second offset angle and is conducive to the improvement of the anti-eddy effect and the roof drainage speed is increased.

Description

technical field [0001] The invention belongs to the field of building water supply and drainage, in particular to a rainwater bucket, in particular to a double-mounted high-efficiency siphon rainwater bucket. Background technique [0002] The rainwater bucket is installed at the entrance where the roof rainwater enters the rainwater pipe from the gutter, which can quickly drain the roof rainwater, avoid the formation of an excessive vortex, stabilize the water level in front of the bucket, reduce aeration, quickly drain the roof rainwater and snowwater, and effectively block Larger debris. The rain bucket can be suitable for different roofs for rainwater drainage by combining with corresponding accessories, such as: concrete roofs, metal roofs, wooden roofs, roofs that consider people walking or greening, roofs with uneven roofs and trapezoidal structures, elevated, etc. [0003] It can be seen that the rainwater bucket is a key part of the drainage system. For the entire r...
