三通阀门在化工、塑料、铸造业中应用广泛，过去大都是人工操作。随着科学技术的发展，自动控制技术已广泛应用于各个生产领域，气控三通阀门就是在这种情况下诞生的。气控三通阀门可以通过电－气控制技术在生产过程中实现自动控制。 1.气缸体　2.活塞　3.活塞杆　4.气缸盖 5.滚柱组件　6.螺旋导套　7.防护盖　8.阀杆 9.调整丝套　10.螺旋套壳体　11.阀体　12.阀口　13.阀芯 气控三通阀门的工作原理如下： 气控三通阀门由上、中、下3部分组成,上部为一双作用气缸，中部为一旋转部组件,下部为一三通球阀。活塞2在气缸上端时，Ⅰ腔与Ⅱ腔相通,当气源从P1进入气缸时，气缸中活塞2在气压的作用下向下运动，活塞杆3带动滚柱5沿螺旋导套壳体导向槽向下运动使螺旋导套6旋转，当活塞2向下运动至气缸下端时，螺旋导套旋转90°，螺旋导套带动球阀阀杆8旋转90°， 阀芯13旋转90°，这样Ⅰ腔与Ⅱ腔隔离，Ⅰ腔与Ⅲ腔相通。反之，当气源从P2进入气缸时，气缸中活塞2在气压作用下向上运动，活塞杆3带动滚柱5向上运动，使螺旋导套6旋转，当活塞2向上运动至气缸上端时，螺旋导套向反方向旋转90°，螺旋导套带动球阀阀杆8反向旋转90°，阀芯13反向旋转90°，这样Ⅰ腔与Ⅲ腔隔离，Ⅰ腔与Ⅱ腔相通。 气控三通阀门可以通过气动电磁换向阀控制P1、P2口的进出气方向来控制。气控三通阀门可以通过的介质为流体、气液混合体及半流体。

Three valves in the chemical, plastics, foundry industry, is widely used in the past, mostly manual. With the development of science and technology, automation technology has been widely used in various production fields, gas control valve is the three links in this case was born. Three air control valve can be electric - gas control technology to achieve automation in the production process. 1. Cylinder 2. Piston 3. Piston rod 4. Cylinder head 5. Roller components 6. Screw guide sleeve 7. Protective cover 8. Stem 9. Adjustment of wire cover 10. Spiral sets of shell 11. Valve 12 . valve port 13. spool Three air control valve works as follows: Three air control valve from the upper, middle and lower 3 parts, the role of the upper part of a pair of cylinder, a rotating central Ministry of components, the lower part of a ball valve. The top of the cylinder when the piston 2, Ⅰ and Ⅱ lumen cavity, when the gas supply from P1 into the cylinder, the cylinder piston 2 downward movement under pressure, the piston rod 3 drive roller 5 driven along the spiral guide sleeve shell downward spiral groove to guide sleeve 6 rotation, when the piston 2 moves downward to the bottom of the cylinder, the screw guide sleeve rotate 90 °, screw guide sleeve driven rotary valve stem 8, 90 °, the spool 13 rotating 90 °, so Ⅰ and Ⅱ cavity isolation chamber, Ⅰ and Ⅲ lumen cavity. Conversely, when the gas supply from P2 into the cylinder, the cylinder piston 2 in the upward movement under pressure, the piston rod 3, the upward movement of drive roller 5 to rotate screw guide sleeve 6, when the piston 2 to move up to the top of the cylinder, the spiral guide sleeve to rotate the opposite direction 90 °, spiral valve stem guide sleeve 8, the reverse rotation drive 90 °, spool 13 counter-rotating 90 °, so Ⅰ and Ⅲ cavity isolation chamber, Ⅰ and Ⅱ cavity lumen. Three air control valve pneumatic solenoid valve controlled by P1, P2 and out of the mouth to control the air direction. Three air control valve for the fluid through the media, liquid and semiliquid mixture.
