Z44HZ48H快速排污阀
Z44HZ48H快速排污阀一、Z44H/Z48H快速排污阀概述Z44H/Z48H快速排污阀是由闸阀演变而来的,利用齿轮转90℃带动阀杆提升实现开启和关闭的目的。Z44H排污阀不仅结构简单、密封性好,而且安装尺寸小、材料耗用少、重量轻、体积小,特别是驱动力矩小,操作简便,易实现快速启闭。二、快速排污阀主要性能规范:型号公称压力试验压力Ps(MPa)适用介质适用介质(℃)阀体密封P4448H-16C1.62.41.76水、蒸汽≤250P4448H-16P4448H-25C2.53.752.75P4448H-25≤425P4448H-40C4.06.04.4P4448H-40≤250三、快速排污阀主要零件材料:零件名称阀体、阀盖阀座、闸板阀杆齿轮轴填料垫片扳手P4448H-16CP4448H-25P4448H-40铸钢铬不锈钢铬不锈钢铬不锈钢油浸石墨石棉盘根橡胶石棉板球墨铸铁四、快速排污阀主要尺寸及重量:公称压力PN(MPa)公称通径DN(mm)-重量(kg)LDD1D2D6bZΦdHLO-1.6251601158565-144-Φ14160180103220013510078-164-Φ18180200114023014511085-164-Φ182202201650250160125100-164-Φ182302402065265180145120-184-Φ182502802880280195160135-208-Φ18280350382.5251601158565-164-Φ14160180103220013510078-184-Φ18180200114020014511085-184-Φ182202201650250160125100-204-Φ182302402065265180145120-228-Φ182502802880280195160135-228-Φ18280350384.025160115856558164-Φ1416018010321801351007866184-Φ1818020011402301451108576184-Φ18220220165025016012510088204-Φ182302402065265180145125110228-Φ182502802880280195160135121228-Φ1828035038)
