The author: Time:2019/10/12

        法兰球阀的阀瓣为一中间有通道的球体,球体环绕自已的轴心作90"旋转以实现阀门的开闭。结构比闸阀和截止阀简单,具有启闭迅速,操作方便,体积小,质量轻,零部件少,流体阻力小等特点,而且法兰球阀的流体阻力小,阻力系数与同长度的管段相等。其结构简单、体积小、重量轻、紧密可靠。
       法兰球阀在操作方面,比较方便,开闭迅速,从全开到全关只要旋转90° ,便于远距离的控制。维修方便,球阀结构简单,密封圈一般都是活动的,拆卸更换都比较方便。并且在全开或全闭时,球体和阀座的密封面与介质隔离,介质通过时,不会引起阀门密封面的侵蚀。适用范围广,通径从小到几毫米,大到几米,从高真空至高压力都可应用。
