Product Details

H71W型对夹止回阀概述:

      H71W型不锈钢对夹止回阀采用新型全部材料采用耐腐蚀不锈钢。可在任何位置的管路上安装,防止介质逆流,锅炉给水系统上回,其连接方式是利用原有管道两端法兰对夹即可投入运行。其各项指标都优于目前市售的任何一种上回阀。它的运用范围广泛用于给排水、消防、建筑、暖通、工业系统。凡水、气、油、酸、碱液、氢、氨、特别消防管道等介质均可使用。例如:可安装于水泵出口处,能避免产生水锤、水击声和破坏性冲击,达到防止逆流和保护设备的目的,有较好节能效果。

H71W对夹止回阀的特点:

      对夹止回阀的阀瓣行程短,阀瓣轻巧,具有弹簧辅助关闭,关阀速度很快。结构长度很短、体积很小、重量很轻、流体阻力小、密封可靠、启闭平稳、耐磨损、使用寿命长、油压、缓闭不受介质影响,有较好节能效果等特点,为阀门的安装、搬运、存放及管道的布置带来很大的便利,并能大量节约材料、降低造价。

用途:

 止回阀用于管路系统,其主要作用是防止介质倒流、防止泵及其驱动电机机反转,以及容器内介质的泄放。止回阀还可用于给其中的压力可能升至超过主系统压力的辅助系统提供补给的管路上。 止回阀根据材质的不同,可以适用于各种介质的管路上。 止回阀安装在管路上,即成为这一完整管路的流体部件之一,其阀瓣启闭过程就要受它所处系统瞬变流动状态所影响;反过来,阀瓣的关闭特性又对流体流动状态产 作用
