虹吸式雨水斗

Siphonic rainwater hoppers

虹吸式雨水斗的作用：可控制天沟水深，防堵效果很好，使用年限长。
对于排水量而言，分RC-50（12L/S），RC-80（30L/S），RC-100（50L/S）三种型号雨水斗；
荣成雨水斗底盘、防水夹圈采用不锈钢304材质，一体式外罩，采用铝合金压铸，表面并经电泳化处理，耐腐蚀性能好，外罩与底盘的连接设计采用专用六角不锈钢螺帽，大大减少了偷盗。

Effect of siphonic rainwater hoppers: can control depth of water in gutters, containment effect is very good, and service life is long.
From the viewpoint of water discharge, rainwater hoppers are divided into three models, i.e. RC-50 (12L/S), RC-80 (30L/S) and RC-100 (50L/S).
Chassis and waterproof clamp ring of Rongcheng rainwater hopper employ 304 stainless steel, integrated cover and die-casting of aluminum alloy, the surface is processed with electrophoresis with good corrosion resistance, connection between cover and chassis is designed by means of hexagonal stainless steel nuts to reduce steal greatly.

固定系统Fixed system

雨水横管固定有专业的二次悬吊系统，悬吊系统包括与管道平行的方形钢管，管道与方形钢管间的连接管卡(根据不同的管径，每隔0.8至2.0米布置管卡)，用于固定钢导管的骑卡及镀锌小插销。
荣成悬吊系统可以防止在刚性安装的排放系统中，由于热胀冷缩受到阻隔而产生的力会对建筑结构的破坏，吸收热胀冷缩导致的管道位移。同时，还可以避免管道因为悬挂受力而变形。
无论是系统震动带来的外力，还是热胀冷缩引起的内力，甚至是悬挂管道承受的重力，都由连接件传至方形钢导管，避免引起系统的变化，减少对于建筑结构的影响。
荣成悬吊系统除了可以起到固定管道，转移管道受力的作用，还有助于增加屋面到水平管的间距， 而不影响管道的水平受力。
总而言之，荣成悬吊系统虽然是虹吸式雨水排放系统的辅助部分，却起到至关重要的保护的作用。
荣成悬吊系统的所有固定配件表面均经镀锌处理，外表美观，经久耐用。

The horizontal rainwater pipe is fixed with specialized secondary suspension system, which includes square steel pipes parallel to pipelines, connecting pipe clamps between pipelines and square steel pipes (arranged every 0.8~2.0m in accordance with different pipe diameters), riding clamps for fixing steel conduits and galvanized small pins.
Rongcheng suspension system can prevent damage of force produced due to obstruction of expansion caused by heat and contraction caused by cold to building structures in rigidly installed drainage system and displacement of pipelines caused by absorption of expansion caused by heat and contraction caused by cold. In the meantime deformation of pipelines due to stress on suspension can be avoided.
Both external force brought by vibration of system and internal force due to expansion caused by heat and contraction caused by cold, and even the gravity borne by suspension pipelines are transmitted by connectors to square steel pipes to avoid changes of system and to reduce influences on building structures.
Besides effects of fixing pipelines and transferring stress on pipelines, Rongcheng suspension system is also helpful to increase space between roof and horizontal pipes without affecting horizontal stress on pipelines.
In a word, although being auxiliary part of the siphonic rainwater drainage system, Rongcheng suspension system plays a critical role of protection.
Thanks to galvanized treatment for surfaces of all stationary fittings, Rongcheng suspension system is elegant in appearance and durable in use.
