</p><p> <span style="font-size:16px;"> 球閥是由旋塞閥演變而來，它的啟閉件是一個球體，利用球體繞閥桿的軸線旋轉(zhuǎn)90°實現(xiàn)開啟和關(guān)閉的目的。球閥在管道上主要用于切斷、分配和改變介質(zhì)流動方向，設(shè)計成V形開口的球閥還具有良好的流量調(diào)節(jié)功能。球閥的材質(zhì)有防腐襯氟球閥，鑄鐵球閥，使用場合不同，材料的選用也不同，球閥的使用性能及優(yōu)點有哪些呢？具有低的流阻(實際為0);因在工作時不會卡住(在無潤滑劑時)，故能可靠地應(yīng)用于腐蝕性介質(zhì)和低沸點液體中;在較大的壓力和溫度范圍內(nèi)，能實現(xiàn)完全密封;可實現(xiàn)快速啟閉，某些結(jié)構(gòu)的啟閉時間*為，以保證能用于試驗臺的自動化系統(tǒng)中?？焖賳㈤]閥門時，操作無沖擊;關(guān)閉件能承受關(guān)閉時的高壓差。全焊接閥體的球閥，可以直埋于地下，使閥門內(nèi)件不受浸蝕，使用壽命可達(dá)30年，是石油、天然氣管線理想的閥門。球形關(guān)閉件能在邊界位置上自動定位;工作介質(zhì)在雙面上密封可靠;在全開和全閉時，球體和閥座的密封面與介質(zhì)隔離，因此高速通過閥門的</span><span

style="font-size:16px;">由于球閥通常用橡膠、尼龍和聚四氟乙烯作為閥座密封圈材料，因此它的使用溫度受到閥座密封圈材料的限制。球閥主要的閥座密封圈材料就是聚四氟乙烯（PTFE），它對幾乎所有的化學(xué)物質(zhì)都是惰性的，且具有摩擦系數(shù)小、性能穩(wěn)定、不易老化、溫度適用范圍廣和密封性能優(yōu)良的綜合性特點。但聚四氟乙烯的物理特性，包括較高的膨脹系數(shù)，對冷流的敏感性和不良的熱傳導(dǎo)性，要求閥座密封的設(shè)計必須圍繞這些特性進(jìn)行。閥座密封的塑性材料也包括填充聚四氟乙烯、尼龍和其他許多材料。但是，當(dāng)密封材料變硬時，密封的可靠性就要受到破壞，特別是在低壓差的情況下。此外，像丁青橡膠這樣的合成橡膠也可用作閥座密封材料，但它所適用的介質(zhì)和使用的溫度范圍藥受到限制。另外，如果介質(zhì)不潤滑，使用合成橡膠容易卡住球</span><span
