Air three-way ball valve is a three channel rotary ball valve, which is used for medium diversion, confluence and flow direction conversion. Any pipeline can be used as inlet or outlet. Pneumatic three-way ball valve is divided into pneumatic three-way L-type ball valve and pneumatic three-way T-type ball valve, which can meet the requirements of different production processes. The pneumatic three-way L-shaped ball valve cuts off two of the three pipelines, and the pneumatic three-way T-shaped ball valve realizes the confluence and diversion of the three pipelines.

气动三通球阀的控制

Control of pneumatic three-way ball valve

气动三通球阀与电气阀门定位器配套，输入4～20mADC信号及0.4～0.7MPa气源即可控制运转，实现对压力、流量、温度、液位等参数的调节。亦配行程限位开关、电磁阀、减压阀及0.4-0.7MPa气源可实现开关操作，并送出二对无源触点信号指示上海良工阀门的开关。

The pneumatic three-way ball valve is matched with the electric valve positioner. The operation can be controlled by inputting 4 ~ 20mADC signal and 0.4 ~ 0.7MPa air source to realize the adjustment of pressure, flow, temperature, liquid level and other parameters. It is also equipped with travel limit switch, solenoid valve, pressure reducing valve and 0.4-0.7mpa air source to realize switching operation, and send two pairs of passive contact signals to indicate the switching of Shanghai Lianggong valve.

气动三通球阀的特点

Characteristics of pneumatic three-way ball valve

(1)流体阻力小，其阻力系数与同长度的管段相等。

(1) The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section with the same length.

(2)结构简单、体积小、重量轻。

(2) The utility model has the advantages of simple structure, small volume and light weight.

(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。

(3) It is tight and reliable. At present, plastic is widely used as the sealing surface material of ball valve, with good sealing performance. It has also been widely used in vacuum system.

(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。

(4) It is easy to operate and open and close quickly. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.

(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。

(5) The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.

(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，不会引起气动三通球阀密封面的侵蚀。

(6) When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the sealing surface of the pneumatic three-way ball valve.
