电动闸阀和电动截止阀的区别

发布日期:2019-12-09 作者:大才阀门 点击:

电动阀简单地说就是用电动执行器控制阀门,从而实现阀门的开和关。其可分为上下两部分,上半部分为电动执行器,下半部分为阀门。动作力距比电动阀门大,电动闸阀开关动作速度可以调整,结构简单,易维护,动作过程中因气体本身的缓冲特性,不易因卡住而损坏,但必须有气源,且其控制系统也比电动阀门复杂。电动截止阀和法兰闸阀是同属一个类型的阀门,由电动执行机构或气动执行机构和截止阀两部分组成,区别在它的关闭件是个阀体,阀体绕阀体中心线作旋转来达到开启、关闭的一种阀门。 闸阀在管路中主要用来做切断、分配和改变介质的流动方向。二片式球阀,三片式球阀,是近年来被广泛采用的一种新型阀门。
