            对夹式止回阀

            铸钢对夹连接止回阀

             对夹式止回阀主要作用是防止介质倒流,是一种依靠介质压力开启和关闭的自动阀门。以往国内普遍采用的是H44型法兰连接旋启式止回阀和H41型法兰连接升降式止回阀,这种传统的法兰式止回阀体积笨大,流体阻力大,阀门关闭时水锤压力高,安装、维修难,使用寿命短。

            对夹式止回阀

            对夹止回阀系列具有结构长度短,体积小重量轻,阀瓣关闭快速,水锤压力小,流道通畅,流体阻力小,水平管道或垂直管道均可使用,安装方便,动作灵敏,密封性能好,阀瓣行程短、关阀冲击力小,简单紧凑、造型美观,使用寿命长、可靠性高,防止介质倒流,自动控制等优点。

            对夹式止回阀主要适用于城?#23567;?#24037;业?#26696;?#23618;建筑给水、排水管网上。由于对夹式止回阀的结构长度比?#35805;?#27861;兰式止回阀短,对有安装空间限制的场所较为适用。

            压力范围: PN1.0~42MPa、Class150~2500
            口径范围: DN15~1500,NPS 1/2 ~60
            工作温度: -29~425℃(碳钢)、-196~540℃(不锈钢)

            对夹式止回阀的标准规范

            设计与制造标准:JB/T 8937、API 594、API 6D
            结构长度标准:JB/T 8937、API 594、API 6D
            配管法兰标准:JB/T 74~90、GB/T 9112~9124、GB/T 13402、HG 20592~20635、SH 3406、ASME B16.5、API 605、ASME B 16.47、DIN 2543~2548
            压力温度等级标准:JB/T 74、GB/T 9124、HG 20604~20625、ANSI B16.34、DIN 2401、SH 3406
            检验与试验标准:JB/T 9092、API 598
