空氣式三通球閥是一種三通道回轉(zhuǎn)式球閥，用于介質(zhì)的分流、合流和流向轉(zhuǎn)換，任何管道均可用作進口或出口。氣動三通球閥分為氣動三通L型球閥和氣動三通T型球閥兩種，可滿足不同生產(chǎn)工藝要求。氣動三通L型球閥是將三個管路中的兩個管路切斷，氣動三通T型球閥實現(xiàn)三個管路的合流和分流。
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.

氣動三通球閥的控制
Control of pneumatic three-way ball valve
氣動三通球閥與電氣閥門定位器配套，輸入4～20mADC信號及0.4～0.7MPa氣源即可控制運轉(zhuǎn)，實現(xiàn)對壓力、流量、溫度、液位等參數(shù)的調(diào)節(jié)。亦配行程限位開關(guān)、電磁閥、減壓閥及0.4-0.7MPa氣源可實現(xiàn)開關(guān)操作，并送出二對無源觸點信號指示上海良工閥門的開關(guān)。
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.

氣動三通球閥的特點
Characteristics of pneumatic three-way ball valve
(1)流體阻力小，其阻力系數(shù)與同長度的管段相等。
(1) The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section with the same length.
(2)結(jié)構(gòu)簡單、體積小、重量輕。
(2) The utility model has the advantages of simple structure, small volume and light weight.
(3)緊密可靠，目前球閥的密封面材料廣泛使用塑料、密封性好，在真空系統(tǒng)中也已廣泛使用。
(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，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠距離的控制。
(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)維修方便，球閥結(jié)構(gòu)簡單，密封圈一般都是活動的，拆卸更換都比較方便。
(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)在全開或全閉時，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時，不會引起氣動三通球閥密封面的侵蝕。
(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.
