Q45F三通球閥產(chǎn)品特點(diǎn):
一、兩閥座密封三通球閥結(jié)構(gòu)緊湊、外型美觀、密封性能好。
它能實(shí)現(xiàn)對(duì)管道中介質(zhì)流向的切換。也能使相互垂直的兩個(gè)通道連通或關(guān)閉。（如流向圖A）
二、四閥座密封三通球閥造型美觀，結(jié)構(gòu)緊湊合理，它不僅可實(shí)現(xiàn)介質(zhì)流向的切換，也可使三個(gè)通道相互連通，同時(shí)也可關(guān)閉任一通道，使另外兩個(gè)通道連通，靈
活控制管路中介質(zhì)的合流或分流。（如流向圖B）
Features
1. In the double-seat sealing design, the 3-way ball valve enjoys compact structure,goodly configuration ａnd favorable sealing performance. The valve could make a realization the switching of flow direction of the medium inside the pipeline, furthermore, it also could connectshut-down the two orthogonal passages.（As shown in Flow Graph A）
2.In the 4-seat sealing design, the 3-way ball valve enjoys reasonable, compact structure ａnd goodly configuration. The valve could not only make a realization the switching of flow direction of the medium inside the pipeline, but also connect the 3 passages on another. Meanwhile, the valve also features the capacity of shutting-down one of the 3 passages while connecting the other 2 ones for the flexible control of the convergent flowshunting of the medium in pipelines.（As shown in Flow Graph B）

備注：三通球閥一般采用兩閥座結(jié)構(gòu)，如流向圖A所示兩種工況。選用兩閥座L型結(jié)構(gòu)（即Q44型）。流向圖B中①和④兩種工況亦可選用兩閥座T型結(jié)構(gòu)（即Q45型）。流向圖B 中②和③兩種工況必須選用四閥座T型結(jié)構(gòu)（即Q45型）。
其余工況也可選用四閥座結(jié)構(gòu),但應(yīng)在訂貨合同中注明閥座結(jié)構(gòu)。如閥門有其它要求請(qǐng)參閱樣本《球閥的型號(hào)編制方法》填寫相應(yīng)的要求代號(hào)。
