型号:JX214910H71W 对夹升降式止回阀 | $n型号:JX214935美标蝶形止回阀 | $n型号:JX214919H46H法兰双瓣旋启式止回阀 | $n
$n针对国内传统使用的H41型法兰连接升降式止回阀具有体积笨大,流体阻力大,阀门关闭时水锤压力高,安装、维修难,使用寿命短等缺点。针对传统法兰结构止回阀存在的问题,研制了对夹式止回阀系列,H71对夹式升降式止回阀具有结构长度短,体积小、重量轻,阀瓣关闭快速,水锤压力小,安装方便,流体阻力小,动作灵敏、密封性能好,阀瓣行程短、关阀冲击力小,整体结构、简单紧凑,使用寿命长、可靠性高等特点。对夹升降式止回阀由阀体、阀瓣、弹簧等组成,水平或垂直安装于管路系统,防止介质倒流。$n
$n$n产品特点$n$n$n1. 结构长度短,其结构长度只有传统法兰止回阀的1/4~1/8;
$n2. 体积小、重量轻,其重量只有传统法兰止回阀的1/4~1/20;
$n3. 阀瓣关闭快速,水锤压力小;
$n4. 水平管道或垂直管道均可使用,安装方便;
$n5. 流道通畅、流体阻力小;
$n6. 动作灵敏、密封性能好;
$n7. 阀瓣行程短、关阀冲击力小;
$n8. 整体结构、简单紧凑、造型美观;
$n9. 使用寿命长、可靠性高。$n
