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參閱樣本《球閥的型號編制方法》填寫相應(yīng)的要求代號。
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-seatcould 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.

訂貨須知:
手動法蘭球閥主要用于截?cái)嗷蚪油ń橘|(zhì),也可用于流體的調(diào)節(jié)與控制。與其它閥類相比,球閥具有如下的一些優(yōu)點(diǎn): 流體阻力小,球閥是所有閥類中流體阻力最小的一種,即使是縮徑球閥,其流體阻力也相當(dāng)小。 開關(guān)迅速、方便,只要閥桿轉(zhuǎn)動90°,球閥就完成了全開或全關(guān)動作,很容易實(shí)現(xiàn)快速啟閉。 密封性能好。球閥閥座密封圈一般采用聚四氟乙烯等彈性材料制造,易于密封,而且球閥的密封力隨著介質(zhì)壓力的增加而增大。閥桿密封。球閥啟閉時(shí)閥桿只作旋轉(zhuǎn)運(yùn)動,因此閥桿的填料密封不易被破壞,而且閥桿倒密封的密封力隨著介質(zhì)壓力的增加而增大。球閥的啟閉只做90°轉(zhuǎn)動,故容易實(shí)現(xiàn)自動化控制和遠(yuǎn)距離控制,球閥可配置氣動裝置、電動裝置、液動裝置、氣液聯(lián)動裝置或電液聯(lián)動裝置。球閥通道平整光滑,不易沉積介質(zhì),可以進(jìn)行管線通球。 公稱通徑:DN15-500mm; 公稱壓力:PN1.6-2.5mpa; 適用介質(zhì):水、氣、油品、天然氣和酸堿腐蝕性、氧化性、尿素等介質(zhì); 適用溫度:-20-150-300℃; 驅(qū)動方式:手動、氣動、電動等; 閥體材質(zhì):碳鋼、鑄鋼、304、316、316L不銹鋼等;
