球阀的工作原理
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。
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。
球阀的主要优点
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。
The working principle of ball valve
Ball valve it has rotated 90 degrees, the cock body for a sphere, a round hole or tunnel through its axis. Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium, it just has to rotate 90 degrees of operating and small rotational torque can be closed tightly. Ball valve is suitable to do the most switch, cut-off valve, ball valve but recent development have designed to make it with throttling and control flow, such as V type ball valve.
Ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields. Ball valve body can be a whole, also can be combined.
The main advantage of the ball valve
1. The fluid resistance is small, little flow resistance full size of ball valve.
2. Simple structure, small volume, light weight.
3. Compact and reliable. It has two sealing surface, and the widely use of all kinds of plastic ball valve sealing surface of materials, good sealing, can realize completely sealed. Have 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, simple structure of ball valve, 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 isolation, 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.) wipe because of ball valves in the process of opening and closing and so can be used to bring in the medium of suspended solid particles.
