三、进口微阻缓闭蝶式止回阀工作原理
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。止回阀一般分为升降式、旋启式、蝶式及卧式等四种类型,通式升降式止回阀应安装于水平管路上,立式升降式止回阀和底阀一般安装在垂直管路上,并且介质自下而上流动,旋启式止回阀安装位置不受限制,通常安装于水平管路,但也可以安装于垂直管路或倾料管路上。
四、进口微阻缓闭蝶式止回阀性能特点
1、体积小,重量轻,结构长度只有普通旋启式止回阀的三分之一左右;
2、缓闭系统性能优良,不受管道中介质影响;阀板先速关后慢关,可防止破坏性水锤的产生;启闭平稳,无震动,无噪音;
3、橡胶密封,密封效果好,耐磨损,使用寿命长;
4、阀门流阻小,有明显的节能效果。
