The siphon drainage system is an important part of the building water supply and drainage system. Its mission is to promptly eliminate rainwater and snow water falling on the roof of the building, avoiding the formation of roof water and threatening the roof, or causing rainwater overflow, roof leakage, etc. Water accidents to ensure people's normal life and production activities. The siphon drainage system is characterized in that the horizontal pipe is formed without a slope, and a full pipe flow is formed to discharge the accumulated water on the roof at an extremely fast speed. The main components of the siphon drainage system consist of a siphon drainage pipe and a rainwater bucket.
Rainwater bucket for siphonic roof rainwater drainage system. It has functions such as gas-water separation and eddy current prevention. The water depth before the bucket can be effectively controlled. When the water level in front of the bucket reaches the designed water depth, the siphon full tube pressure flow is formed in the system.
In general, the design of the rain bucket is one of the key points for the entire siphon system to work according to the design requirements. The better its flow stability, the lower the roof water level required for siphon production, and the better the overall performance. .
The standard rainwater bucket is composed of a rainwater bucket base (PE material), a disc (ASA), and a grill top cover (PE). In addition, general-purpose insulating bases, fixing parts, flanges, welding pieces, fire protection caps, micro heating coils and other accessories are available upon request. The rated flow of the rainwater bucket is divided into 12L/s, 25L/s, 40L/s, 60L/s and 72L/s. The most commonly used rainwater buckets are rated flow of 25L/s and 40L/s.
