三通球阀分T型三通球阀和L型三通球阀。T型能使三条正交的管道相互联通和切断第三条通道，起分流、合流作用。L三通球阀型只能连接相互正交的两条管道，不能同时保持第三条管道的相互连通，只起分配作用。
Three way ball valve is divided into T type and L type three way valve three way valve. T type channels to make the three orthogonal interconnected and cut off the third channel, has split, merge function. Two pipeline L three ball valve type can only be connected mutually orthogonal, communicated with each other can not keep the third pipelines at the same time, only as a distribution function.

它的工作原理如下
It works as follows
A、开启过程
A, open process
1在关闭位置，球体受阀杆的机械施压作用，紧压在阀座上。
1 in the closed position, the valve ball mechanical pressure action, pressed on the seat.
2当逆时针转动手轮时，阀杆则反向运动，其底部角形平面使球体脱开阀座。
2 when the handwheel counterclockwise, the stem is the reverse movement, the bottom of the angular plane to disengage the ball seat.
3阀杆继续提升，并与阀杆螺旋槽内的导销相互作用，使球体开始无摩擦地旋转。
3 stem continues to improve, and with the spiral groove of the guide pins stem interactions, the ball began to spin without friction.
4直至到全开位置，阀杆提升到极限位置，球体旋转到全开位置。
4 up to the fully open position, the valve stem to the limit position, rotate the sphere to the fully open position.
B、关闭过程
B, the closing process
1关闭时，顺时针旋转手轮，阀杆开始下降并使球体离开阀座开始旋转。
1 off, rotate the hand wheel clockwise, the stem began to decline and to leave the seat to rotate a sphere.
2继续旋转手轮，阀杆受到嵌于其上螺旋槽内的导销的作用，使阀杆和球体同时旋转90°。
2 continue rotating the handwheel, the stem is embedded in the spiral groove of the guide pin, the stem and ball rotating 90 °.
3快要关闭时，球体已在与阀座无接触的情况下旋转了90°。
The 3 is closed, the sphere has been no contact with the valve seat under the condition of 90 DEG rotation.
4手轮转动的最后几圈，阀杆底部的角形平面机械地楔向压迫球体，使其紧密地压在阀座上，达到完全密封。
4 hand rotation of the final laps, the stem at the bottom of the angular plane mechanical wedge pressure sphere, so closely pressed on the seat, to be completely sealed.
Q44F/Q45F-16~64C/P/R国标法兰三通球阀 的结构特点
Structural features of Q44F/Q45F-16~64C/P/R standard flange three way ball valve
1、启闭无摩擦。这一功能完全解决了传统阀门因密封面之间相互摩擦而影响密封的问题。
1, open and close without friction. This function completely solve the traditional valve sealing surface due to friction between the sealing problems.
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，降低成本。
2, jacket type structure. Can be directly online inspection and repair of the valve installed in the pipe, can effectively reduce the plant parking, reduce costs.
3、单阀座设计。消除了阀门中腔介质因异常升压而影响使用安全的问题。
3, single seat design. Remove the valve in the cavity medium affected by abnormal use boost security problems.
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。
4, low torque design. Special structural design of the stem, just with a little hand to easily open and close the valve.
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，在各种工况下密封性能都有可靠保证。
5, wedge-shaped seal structure. The valve stem is provided by the mechanical force, the ball seat on the wedge pressure to seal, the valve seal is not affected by the impact of changes in pipeline pressure, the sealing performance under various conditions have a reliable guarantee.
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，不仅消除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。
6, the sealing surface of the self-cleaning structure. When the ball roll away from the valve seat, fluid in the pipeline along the sealing surface of the sphere into 360 DEG through, not only eliminates the high-speed fluid to seat local scour, also washed away the accumulation on the seal face, to achieve self cleaning purposes.
