Q61N美标插焊球阀适宜做开关、切断阀使用,高压对焊球阀的主要特点是本身结构紧凑,密封稳定,结构简单,维修方便,密封面与球面常在闭合状态,不易被介质冲蚀,易于操作和维修,适用于水、溶剂、酸和天然气等一般工作介质,而且还适用于工作条件恶劣的介质,如氧气、过氧化氢、甲烷和乙烯等,在各行业得到广泛的应用。高压对焊球阀阀体可以是整体的,也可以是组合式的。
Q61N美标插焊球阀优点:
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.紧密稳定。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.由于高压对焊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。
