气动球阀在管路中主要用来做切断速度快、分配和改变介质的流动方向。气动球阀是近年来被广泛采用的一种新型阀门，它具有以下优点：   

1． 流体阻力小，其阻力系数与同长度的管段相等。   

2． 结构简单、体积小、重量轻。   

3． 紧密可靠，目前球阀的密封面材料广泛使用塑料、密封性好，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，气动球阀结构简单，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. 因为气动球阀动力源采用的是气体，一般为0.2-0.8MPa压力，相对比较安全。气动球阀如果漏气的话，相对液动、电动来说，气体可以直接排出，对环境没有污染，同时具有较高的安全性。   

9.相对于手动和涡轮转动球阀来说，气动球阀可以大口径配置，（手动和涡轮转动球阀一般都在DN300口径以下，气动球阀目前可以达到DN1200口径。）   

气动球阀已广泛应用于石油、化工、发电、造纸、原子能、航空、火箭等各部门，以及人们日常生活中。

Pneumatic ball valve in the line is mainly used for cutting speed is quick, distribution, and change the flow direction of medium. Pneumatic ball valve is widely used in recent years a new type of valve, it has the following advantages:

1. The fluid resistance is small, its resistance coefficient with section of equal length.

2. Simple structure, small volume, light weight.

3. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.

4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

5. Easy maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient.

6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric ***lation, medium through, can not cause the valve sealing surface erosion.

7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.

8. Because of the power supply adopts pneumatic ball valve is a gas, usually 0.2 0.8 MPa pressure, is relatively safe. If air leakage, pneumatic ball valve relative hydraulic, electric, gas can directly discharge, no pollution to the environment, and has higher security.

9. Relative to manual and turbine rotating ball valves, pneumatic ball valve can be large caliber configuration, (manual and turbine rotating ball valve is generally under 12 caliber, pneumatic ball valve can now be reached 48 ") diameter.)

Pneumatic ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People&＃39;s Daily life.
