V86B高压焊接球阀它具有旋转90度的动作，旋塞体为球体，有圆形通孔或通道通过其轴线。球阀在管路中主要用来做切断、分配和改变介质的流动方向，它只需要用旋转90度的操作和很小的转动力矩就能关闭严密。球阀适宜做开关、切断阀使用，但近来的发展已将球阀设计成使它具有节流和控制流量之用，如V型球阀。

       V86B高压焊接球阀为活接焊接式，自带焊接短管，另外常用还有卡套连接和内螺纹连接。V86B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。球阀阀体可以是整体的，也可以是组合式的。

V86B高压焊接球阀优点：

       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．紧密完好。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。
