气动三通 球阀

气动三通球阀由GT型、DA型、AW型气动活塞式双作用或单作用（弹簧复位式）执行机构组成，有比例调节型（采用电-气阀门定位器，以电信号和压缩空气为动力，接受控制系统输入的0-10mA DC或4-20mA DC电流信号，改变球芯的旋转角度，可实现比例调节动作）。二位切换型（采用电磁换向阀、阀位回讯器，以AC220V或DC24V电源电压和压缩空气作动力，实现对流体介质的快速切换控制）

Pneumatic ball valve by the GT model, DA type, AW pneumatic piston double acting or single acting （spring return） actuator composed of a proportional control type （use of electricity - gas valve positioner to electrical signals and compression air-powered, the control system receiving input 0-10mA DC or 4-20mA DC current signal, change the angle of rotation of the ball core can achieve proportional control action）. Two switch-type （electromagnetic valve, valve back to the hearing to AC220V or DC24V power supply voltage and compressed air, the fluid medium to achieve fast switching control）

1．三通球阀有两座和四座密封结构，阀芯孔道有L型和T型两种结构形式，采用控制阀芯旋转角度，改变阀芯孔道与管道口的连接状态，可实现对三条支管不同的组合控制。三通球阀流通能力大，可控制气体、液体、蒸汽，更适用于控制高粘度，纤维颗粒状的流体。也适用于密封要求较严格的场合。
2．两阀座密封三通球阀具有结构紧凑、外形美观、密封性能好，它能实现对管道中介质流向的切换。也能使相互垂直的两个通道连通或关闭（如流向图A）
3．四阀座密封三通球阀具有造型美观、结构紧凑合理，它不仅可实现介质流向的切换，也可使三个通道相互连通，同时可关闭任意一个通道，使另外两个通道连通，灵活控制管路是介质的合流或分流（如流向图B）。
4．T型阀芯孔道可使三条正交的管道互相连通或切换，起分流或合流作用；L型孔道连接相互正交的两管道。使另一条孔道切断，起改变介质流向作用。

1. There are two and four-way ball valve sealing structure, L-valve and T channels are two kinds of structure, the use of control spool rotation, change the channel and pipe spool port connection status, can achieve three different branch combination control. Ball valve flow capacity, can control the gas, liquid, vapor, but also for control of high viscosity, fiber granular fluid. Sealing requirements are more stringent for the occasion.
2. Two way ball valve seat sealing with compact structure, beautiful appearance, good sealing performance, it can achieve in the medium of the pipeline flow switch. Perpendicular to each other can also connect two channels on or off （such as the flow chart A）
3. Four-way ball valve with a valve seat sealing beautiful shape, compact structure, which not only enables media flow switch also allows three channels interconnected, and can close any channel, connected to the other two channels, flexible control pipeline is the media mixing or diverting service （such as the flow of Figure B）.
4. T-valve allows three orthogonal channel pipes or switch connected to each other, from the confluence of diversion or the role; L-type channels to connect the two orthogonal channels. Another channel to cut off media flow from changes in the role.
