Pressure flow (siphon) rainwater gutters are made of stainless steel. Different parts of the gutter have various structural functions. The rainwater gutter is positioned in the roof layer with an upper cover of an inlet grille. During rainfall, water enters the gutter through the side of the grille cover. As the roof collects water to a certain height, the anti-turbulent device inside the gutter blocks air from entering from the outside while eliminating turbulent conditions, allowing the rainwater to steadily flood and drain into the drainage pipe. The siphon rainwater gutter minimizes the depth of water accumulation in the gutter, reducing the roof's water load to the minimum, while also increasing the rated flow of the gutter. As a leading product in the market, it is highly adaptable and can be partially universal. Its greatest advantage lies in its wide applicability to different roof systems with varying functions and materials. In other words, a single rainwater gutter can be used with the corresponding accessories.Combination options to fit various roof types, such as concrete, metal, and wooden roofs, as well as roofs intended for pedestrian traffic or greenery, or those with trapezoidal sloping surfaces. The rain gutter is a crucial component of the entire siphon system. For the entire siphon roof rainwater drainage system, the primary concern is to prevent air from entering the system through the rain gutter. If air enters the rain gutter directly, it can form air pockets in the pipes, significantly reducing the system's drainage efficiency, ultimately similar to traditional gravity-based drainage systems. Therefore, the rain gutters used in siphon roof rainwater drainage systems must have a cover with an optimized design to prevent air vortices, ensuring that air is not carried into the system by the water flow through the rain gutter entry. This also helps to form a water seal when the water level in the gutter rises to a certain point, completely blocking the entry of air.
