美标不锈钢法兰球阀优点
1.流体阻力小,全通径的球阀基本没有流阻。 2.结构简单、体积小、重量轻。 3.紧密可靠。它有两个密封面,而且目前球阀的密封面材料广泛使用各种塑料,密封性好,能实现完全密封。在真空系统中也已广泛使用。 4.操作方便,开闭迅速,从全开到全关只要旋转90°,便于远距离的控制。 5.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。 6.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。 7.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。 8.由于球阀在启闭过程中有擦拭性,所以可用于带悬浮固体颗粒的介质中。
