style="font-size:16px;">球閥的種類也很多，可以按材料類別、結(jié)構(gòu)形式、用途、密封形式等來(lái)劃分。常見(jiàn)的按照結(jié)構(gòu)形式來(lái)劃分包括：浮動(dòng)球閥，即球體是浮動(dòng)的，依靠介質(zhì)壓力，球體能產(chǎn)生位移，并緊壓在出口端的密封面上，這種結(jié)構(gòu)適用于中低壓環(huán)境；固定球閥球體是固定的，但閥座是可移動(dòng)的，受壓后閥座產(chǎn)生移動(dòng)緊壓在球體上保證密封，這種結(jié)構(gòu)適用于高壓與大口徑的閥門；除此外還有彈性球閥、分體式球閥、焊接球閥、頂裝式球閥等等。按閥體材料劃分，有鑄鋼球閥、鍛鋼球閥、碳鋼球閥、不銹鋼球閥等；按其通道位置可分為直通式、三通式、直角式等；按用途分類，可以分為，截?cái)嗲蜷y、V型調(diào)節(jié)球閥、保溫夾套球閥等；按密封形式，有塑料密封球閥、金屬橡膠雙重密封球閥、金屬硬密封球閥等等。另外，還有不同的驅(qū)動(dòng)配置方式，螺</span><span

style="font-size:16px;">球閥的結(jié)構(gòu)大體上主要由閥體、球體、閥座密封圈、閥桿以及驅(qū)動(dòng)裝置等組成：由于它的啟閉件是球體，在管路中截流時(shí)，介質(zhì)容易對(duì)球體的邊緣造成沖蝕，所以球閥只做全開(kāi)或全關(guān)，同時(shí)它還具有以下特點(diǎn)：1、不受安裝方向的限制，介質(zhì)的流向可任意。流體阻力小，全通徑的球閥基本沒(méi)有流阻。通道平整光滑，不易沉積介質(zhì)。2、密封性能好。球閥有兩個(gè)密封面，閥座密封圈一般采用聚四氟乙烯等材料，密封性好，而且球閥的密封力隨著介質(zhì)壓力的增加而增大，高真空及高壓力均可使用。3、球閥啟閉迅速、輕便。從全開(kāi)到全關(guān)只要旋轉(zhuǎn)90°。4、閥桿密封可靠，球閥啟閉時(shí)閥桿只做旋轉(zhuǎn)運(yùn)動(dòng)，因此閥桿的填料密封不易被破壞，其密封力也會(huì)隨著介質(zhì)壓力的增加而增大。5、球閥的啟閉只做90°轉(zhuǎn)動(dòng)，容易實(shí)現(xiàn)自動(dòng)化控制和遠(yuǎn)距</span><span
