体积小，偏心半球阀靠旋转阀恋来使阀门疏通或闭塞。球阀开关轻便。可以做成很大口径，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，各行业得到广泛的应用。偏心半球阀是一种比较新型的球阀类别，有着自身结构所独有的一些优越性，如开关无摩擦，密封不易磨损，启闭力矩小。这样可减小所配执行器的规格。配以多回转电动执行机构，可实现对介质的调节和严密切断。 偏心半球阀的结构特点：1启闭无摩擦。这一功能xx解决了保守[wiki]阀门[/wiki]因密封面之间相互摩擦而影响密封的问题。2上装式结构。对装在管道上的阀门可直接在线检查与维修，能有效减少装置停车，降低本钱。3单阀座设计。xx了阀门中腔介质因异常升压而影响使用平安的问题。4低扭矩设计。特殊结构设计的阀杆，只需配一个小手把阀门就能轻松启闭。5楔形密封结构。阀门是靠阀杆提供的机械力，将球楔压到阀座上而密封，使阀门的密封性不受管线压差变化的影响，各种工况下密封性能都有可靠保证。6密封面的自清洁结构。当球体倾离阀座时，管线中的流体沿球体密封面成360°均匀通过，不只xx了高速流体对阀座局部的冲刷，也冲走了密封面上的聚积物，达到自清洁的目的。

Small, eccentric half ball straight through rotary valve to clear or block the valve. Valve switch light. Can be made into large-caliber, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often closed state, can not easily be eroded media, been widely used in various industries. Eccentric semi-ball valve is a relatively new type of structure has its own unique number of advantages, such as the switch without friction, seal easy to wear, hoist torque small. This reduces the actuator with the specifications. Accompanied by multi-turn electric actuator, enabling the regulation of the media and close off. Eccentric semi-ball of the structural features: 1 open and close without friction. This feature completely solve the conservative [wiki] valve [/ wiki] due to the friction between the sealing surface affect the sealing problem. Coat structure 2. On the valve installed in the pipe-line inspection and maintenance directly, can effectively reduce the plant parking, reduce capital. 3 single-seat design. Remove the valve in the cavity medium affected by abnormal use boost peace issues. 4 low-torque design. Special structural design of the stem, just with a little hand to easily open and close valves. 5 wedge-shaped seal structure. Valve stem is provided by mechanical force, the ball seat on the wedge pressure to seal against the valve sealing pressure pipeline impact of changes in sealing performance under different conditions have a reliable guarantee. 6 sealing surface of the self-cleaning structure. When the ball away from the seat tilt, the pipeline of the fluid along the sealing surface of the sphere into 360 ° uniform through, not only to eliminate local high-speed fluid on the valve seat erosion, but also washed away the surface of the accumulation of sealing material, to achieve the purpose of self-cleaning .
