Available with pressure flow(Flow Pressure)Rainwater SystemSiphon-type Rainwater Drainage SystemA novel rainwater drainage system developed in recent years.The system has been utilized in numerous prominent projects domestically in recent years.ToApplications. Proven in practice.Compared to traditional standard rainwater drainage systems, this system boasts advantages such as higher drainage capacity, reduced pipe usage, and ease of pipe layout.Dot.The pressure flow roof rainwater drainage system consists of pressure flow rain gutters, rain suspended pipes, rain vertical pipes, buried pipes, and rain outlet pipes. The pressure flow rain gutters have excellent straightening functions, ensuring no air seeps in during the design rainfall intensity. During the rainfall, it is akin to a small pond with a stable water level on the roof draining downwards, passing through the internal roof drainage system and exiting via the discharge pipe. The pipes are in a fully filled pressure flow state, making the roof rainwater drainage process an siphon drainage process. Therefore, referring to the roof rainwater drainage system with siphon drainage capability as a pressure flow rainwater drainage system is quite appropriate. It is widely used in large-span roof buildings such as stadiums and factories, where the roofs are complex in structure, and it is an effective approach to roof drainage.Available with pressure flowSiphonStyle）Rain trays are available in various specifications to meet the actual needs of engineering projects, and they are made ofStainless steelDuring the rainfall process, roof rainwater falls through the inlet grate into a deep trough, with the trough containing porous...FairingStabilizes the rainwater in an eddy state, allowing it to smoothly overflow and exit in a submerged discharge.Drain pipeThe siphon-type rainhead minimizes the water depth entering the gutter, reducing the roof's rain load to the minimum, while also ensuring a greater submergence depth at the rainhead outlet, eliminating the issue of working under design flow conditions.LeakageThe phenomenon has increased the rated flow rate of the rainhead.Pressurized downspoutIncluding flow guide, diffuser, hopper, and discharge short pipe; the lower edge of the flow guide is equipped with a flange, with flow channels distributed on the top and sides, which are fixedly connected to the upper part of the hopper via the flange. The discharge short pipe is made of high-density polyethylene and is connected to the lower part of the hopper through a top flange. The diffuser is located in the space between the hopper and the flow guide, comprising a diffuser plate and several guide vanes fixed around it, each vane pointing towards the center of the diffuser plate and being perpendicular to it. The rainwater hopper of this utility model is easy to install, has high drainage efficiency, and offers simple and effective connection with the system pipeline.
