UPVC 管以其重量轻,不结垢,耐腐蚀,外观美观,施工简便,劳动强度低等优点,在建筑工程中获得了广泛的应用。一、立管的通水能力UPVC 排水立管内壁光滑,水流速度较快,导致UPVC 排水立管内的负压值增大,使卫生器具的水封易于遭受破坏。因此,其立管最大排水能力,宜仍采用铸铁管的相应值。若采用 UPVC 管内壁呈螺旋状三角凸缘的管材为立管,据报导 DN110是排水能力达6.51/s。二、降低嗓音影响普通的 UPVC 排水立管的通水噪音比铸铁管大2-6dB(A)。在立管拐弯及装有消能装置的地方,水的冲击声音尤为突出,夜深人静之时,则感觉更为严重。UPVC 排水立管象铸铁立管一样,在设计上习惯多置于卫生间之间,这不仅占用空间,而且在排水时,噪音难以回避。为了减小立管排水噪音,将 UP-VC 排水立管安装于外墙,排水是噪音就几乎听不到了;为避免被暴晒,UPVC 排水立管应当考虑安装于
UPVC pipe with its light weight, non-fouling, corrosion resistance, beautiful appearance, easy construction, low labor intensity, obtained in the construction of a wide range of applications. First, the riser through the water capacity UPVC drainage riser wall smooth, fast water flow, resulting in UPVC drainage riser negative pressure value increases, so that the sanitary ware seal easily damaged. Therefore, the maximum drainage capacity of its riser, the appropriate value should still be cast iron pipe. If the UPVC pipe wall is spirally shaped triangular pipe flange pipe, it is reported that DN110 is the drainage capacity of 6.51 / s. Second, reduce the impact of ordinary UPVC UPVC drainage pipe water noise than cast iron pipe large 2-6dB (A). In the stand bends and equipped with energy dissipation devices, the impact of water is particularly prominent, when the dead of night, then feel more serious. UPVC drainage riser, like cast-iron riser, is designed to be used more than the bathroom, which not only takes up space, but also in the drainage, the noise is difficult to avoid. In order to reduce the riser drainage noise, the UP-VC drainage riser installed in the outer wall, the drainage is almost noise can not be heard; to avoid being exposed, UPVC drainage riser should be considered installed in
