工作原理
　　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。球阀最适宜做开关、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。

Work priniple
  The globe valve has the working that revolve 90 degrees, the cock body there are circular through hole or gateway passing its shaft wires for the sphere.The globe valve mainly uses to the run direction of making the cutting, allocation and changes dielectric in the piping, it operation and pimping slewing moment of force that need to use to revolve 90 degrees can lock tight.The globe valve is the most suitable proper to make a switch and cut off valve of use, but the recent shape has already designed a globe valve make it has throttling and control flow of use, like V type globe valve.
主要特点
　　球阀的主要特点是本身结构紧凑，密封可靠，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。

Main features
  The main features of globe valve is oneself structure tightly packed, hermetic sealing firm, the structure is simple, maintenance repairs convenience, seal completely surface and sphere often in the close status, not easily drive dielectric erosion, be easy to operation and maintenance repairs, be applicable to water, melting agent, acis and natural gas etc. to generally work dielectric, and still be applicable to operate condition bad dielectric, like oxygen, super - oxadation hydrogen, marsk and ethylene etc., receive a far-ranging application in each craft.The globe valve valve body can be whole as well as be sectional.
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。

Merit
  1.the fluid resistance is small, the globe valve fundamental of whole diameter didn't flow a block.
   2.the structure is simple, small volume, the weight is light.
   3.close and dependable.It has two hermetic sealing surface, and the hermetic sealing surface of the globe valve material extensively uses various plastics currently and seal completely sex well, can carry out complete hermetic sealing.Have already extensively used as well in the uvauum system.
   4.the operation is quickly convenient, open to shut, arrive whole passeses from the full opening as long as revolving 90 °, easy to long-distance leave of control.
   5.the maintenance repairs is convenient, the globe valve structure is simple, the hermetic sealing ring all generally is a mobile, dismantles to unload to replace all more convenient.
   6.in the full opening or all shut, the hermetic sealing surface and dielectric separation of sphere and valve seat, when the dielectric passes can't spark the corrosion that seals completely surface in the valve portal.
   7.the appliance range is wide, the diameter arrived several mms since the childhood and greatly arrived several rices, from higher - uvauum go to the high pressure force could apply.
   8.globe valve's shutting in the Qi has already wiped sex in the process, so is more available than the dielectric that the tape suspends solid grain amid.

 用途：本阀适用于公称压力≤1.6MPa 的水、蒸汽、油品等非腐锈性介质的管路上，作启闭用，其最大优点为启闭迅速。

Use:This valve compliant male calls the piping of the etc. non- Fu rust dielectric of water, steam and oil article of the press ≤ 1.6 MPas up, make Qi to shut to use, its biggest merit for the Qi shut quickly.

阀的型号编制方法说明　　球阀的类型代号为Q。低温球阀前加“D”；保温球阀前加“B”。 　　

　手轮、手柄和扳手传动省略代号。 　　

　公称压力代号用阿拉伯数字表示，其数值是以兆帕为单位的公称压力值的10 倍。用于电站工业的阀门，当介质最高温度超过530℃时，其数值是以兆帕为单位的工作压力值的10 倍。
