        衬氟直流截止阀简述
        Time:2019-4-3 来源:本站原创
        衬氟直流截止阀

            衬氟直流截止阀主要以塞形的阀瓣来开启或者关闭阀门,内部的密封面?#35805;?#20197;锥?#20301;?#32773;平面为主,阀瓣在介质的中心以直线方式运动。
            衬氟直流截止阀的阀杆升降形式?#35805;?#20998;为两种,一种为阀杆本身做升降而手轮?#27426;?#21478;外一种为阀体上设置好螺母然后阀杆和手轮一起做升降运动。?#35805;?#27492;类截止阀只有全开和全关两种状态,不存在节流和调节的功能。
            衬氟直流截止阀的密封?#35805;?#20026;强制密封,所以在阀门启闭的时候,阀瓣需要外部对其施加?#27426;?#30340;压力来保证密封面不产生泄漏。而在介质从阀瓣?#36335;?#36827;入的时候,则需要克服阀杆和阀体本身摩擦产生的阻力。所以衬氟直流截止阀?#35805;?#20851;闭阀门所需要的力矩比开启阀门所需要的力矩大。
