一 球型止回阀简介
球型止回阀又称逆止阀,其作用是防止管路中的介质倒流。启闭件靠介质流动和力量自行开启或关闭,以防止介质倒流的阀门叫止回阀。止回阀属于自动阀类,主要用于介质单向流动的管道上,只允许介质向一个方向流动,以防止发生事故。
二 球型止回阀结构性能特点
1、结构长度短,其结构长度只有传统法兰止回阀的1/4~1/8
2、体积小、重量轻、其重量只有传统微阻缓闭止回阀的1/4~1/20
3、阀瓣关闭快速,水锤压力小
4、水平或垂直管道均可使用,安装方便
5、流道通畅、流体阻力小
6、动作灵敏、密封性能好
7、阀瓣行程短、关阀冲击力小
8、整体结构、简单紧凑、造型美观
9、使用寿命长、可靠性高
