Description

Technical Field

[0001] The utility model relates to the technical field of siphon drainage systems, in particular to a siphon type anti-vortex device. Background Art

[0002] The siphon drainage system is an important part of the building's water supply and drainage system. Its task is to promptly remove rainwater and snow water that fall on the roof of the building to avoid the formation of roof water accumulation that threatens the roof, or causes water disasters such as rainwater overflow and roof leakage. The characteristic of the siphon drainage system is that a full pipe flow is formed without a slope in the horizontal pipe, and the accumulated water on the roof is drained at an extremely fast speed. Among them, the anti-vortex device is an important accessory of the siphon drainage system. During use, the anti-vortex device of the existing siphon drainage system has a top cover that is installed on the siphon rainwater bucket by a number of screws. If a blockage occurs in the siphon rainwater bucket for cleaning, it is necessary to use tools to screw the various screws to disassemble and assemble the top cover, resulting in cumbersome disassembly and assembly operations on the top cover on the siphon rainwater bucket, affecting the convenience of later cleaning and maintenance of the siphon rainwater bucket. Therefore, we propose a siphon anti-vortex device to solve the above problems. Utility Model Content
