上海京蝶閥門(mén)制造有限公司本著以質(zhì)量求生存、靠創(chuàng)新求發(fā)展、堅(jiān)持沒(méi)有只有更好的經(jīng)營(yíng)理念。不斷為客戶(hù)用戶(hù)提供更加適合國(guó)情的閥門(mén)設(shè)備。
Q45F三通球閥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。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。
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(mén)有其它要求請(qǐng)參閱樣本《球閥的型號(hào)編制方法》填寫(xiě)相應(yīng)的要求代號(hào)。
Remarks:
Double-seat configuration design is generally utilized for 3-way ball valve as shown in the 2 operating conditions in Flow Graph A which apply the L-Shaped construction with double-seat（Type Q44）.With regard to the 2 conditions of ① and ④ in Flow Graph B, the T-shaped construction with double-seat could also be applied（Type Q45）.In the ② and ③ conditions in this graph, the choice of the construction must be limited to T-shaped ones with 4-seat（Type Q45）. For other kinds of operating conditions, the construction with 4-seat
could also be applied, however, the construction of the relevant valve seats should be referred in advance in the contract for future delivery. For other requirements please refer to the sample of Organizing Method for Types of Ball Valves and fill in corresponding code numbers as required.
