  • 产品描述
    • 商品名称: 8500X-16Q沟槽泄压阀
    • 商品编号: 1100456456558891008

    阀门某一规格批量制造时,应委托权威性机构进行以下性能的检测:

    阀门某一规格批量制造时,应委托权威性机构进行以下性能的检测:
    ①阀门在工压状况下的启闭力矩;
    ②在工压状况下,能保证阀门关闭严密的连续启闭次数;
    ③阀门在管道输水状况下的流阻系数的检测。
    4.2阀门在出厂前应进行以下的检测:
    ①阀门在开启状况下,阀体应承受阀门工压值二倍的内压检测;
    ②阀门的关闭状况下,两侧分别承受1.1倍阀门工压值,无渗漏;但金属密封的蝶阀,渗漏值亦不大于相关要求。
    五,暗杆闸阀的内外防腐
    5.1阀体(包括变速传动箱体)内外,首先应抛丸清砂除锈,力求静电喷涂粉状无毒环氧树脂,厚度达0.3mm以上。特大型阀门静电喷涂无毒环氧树脂有困难时,亦应刷涂、喷涂相似的无毒环氧漆。
    5.2阀体内部以及阀板各个部位要求全面防腐,一方面浸泡在水中不会锈蚀,在两种金属之间不产生电化学腐蚀;二方面表面光滑使过水阻力减少。
    5.3阀体内防腐的环氧树脂或油漆的卫生要求,应有相应权威机关的检测报告。化学物理性能亦应符合相关要求。
