一、兩閥座密封三通球閥結構緊湊、外型美觀、密封性能好。它能實現對管道中介質流向的切換。也能使相互垂直和兩個通道兩桶或關閉(如流向圖A)。
二、四閥座密封三通球閥造型美觀，結構緊湊合理，它不僅可實現介質流向的切換，也可使三個通道相互連通，同時也可關閉任一通道，使另外兩個通道連通，靈活控制管路中介質的合流或分流(如流向圖B)。
1.in the double-seat sealing design,the 3-way ball valve enjoyscompact structure,goodly configuration and favorable sealingperformance.The value could make a realization the switching offlow direction of the medium inside the pipeline,furthermore,it also could connect or shut-down the two orthogonal passages(As shown in Flow Graph A).
2.ln the 4-seat sealing design,the 3-way ball value enjoys reasonable,compact structure and goodly configuration.The value could not onlymake a realization the swithing off low direction of the medium insidethe pipeline,but also connect the 3 passages on another.Meanwhile,the value also features the capacity of shutting-down one of the 3passages while connecting the other 2 0nes for the flexible controlof the convergent flow or shunting of the medium in pipelines (As shown in Flow Graph B). |

Remarks:
Double-seat configuration design is generally utilized for 3-way ball value as shown in the 2 0pratingconditions in Folw Graph A which apply the L-Shaped construction with double-seat(Type Q44).With regard to the 2 condition of ①and ④ in flow Graph B,the T-shaped construction with double-seat could also be applied(Type Q45).ln the ② and ③ conditions in this graph, the choice of the cinstruction must be limited to T-shapedones with 4-seat(Type Q45).For other kinds of opeqating conditions, the construction with 4-seat could also be applied,however,the construction of the relevent valve seats should be referred in advance in the contractfor future delivery.For other requirements please refer to the sample of Organizing Methord for Types of Ball Valves and fill in corresponding code numbers as required. |
