style="text-indent:25px">球閥具有的優(yōu)點(diǎn)：1．流體阻力小，其阻力系數(shù)與同長度的管段相等。2.結(jié)構(gòu)簡單、體積小、重量輕。3．緊密可靠目前球閥的密封面材料普遍使用塑料、密封性好，在真空系統(tǒng)中也已普遍使用。4．操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠(yuǎn)距離的控制。5.維修方便，球閥結(jié)構(gòu)簡單，密封圈一般都是活動的，拆卸更換都比較方便。6.在全開或全閉時，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時，不會引起閥門密封面的侵蝕。7.適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應(yīng)用。</p><p style="text-indent:25px">球閥一般有縮徑和不縮徑通道兩種結(jié)構(gòu)。無論那種結(jié)構(gòu)，球閥的流阻系數(shù)都比較小。特別是所謂全流量型，即不縮徑的球閥，由于其通道直徑等于管道內(nèi)徑，局部阻力損失只有同等長度管道的摩擦阻力，即在所有閥門中，這種球閥的流阻較小。在火箭發(fā)射及其試驗(yàn)系統(tǒng)中，要求輸送管道的阻力越小越好。減少管路系統(tǒng)的阻力有兩個途徑:一是降低流體流速，為此需要增大管徑和閥門通徑，這對于管路系統(tǒng)的經(jīng)濟(jì)性往往會產(chǎn)生不利的影響，特別對低溫輸送系統(tǒng)(液氫)是極為不利的。如何使球閥的應(yīng)用壽命更加長久？</p><div

style="text-indent:25px">適用場合：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。球閥的截止作用是靠金屬球體在介質(zhì)的作用下，于塑料閥座之間相互壓緊來完成的（浮動球球閥）。閥座密封圈在一定的接觸壓力作用下，局部地區(qū)發(fā)生彈塑變形。這一變形可以補(bǔ)償球體的制造精度和表面粗糙度，保證球閥的密封性能。又由于球閥的閥座密封圈通常采用塑料制成，故在選擇球閥的結(jié)構(gòu)和性能上，要考慮球閥的耐火和防火，特別是在石油、化工、冶金等部門，在易燃、易爆介質(zhì)的設(shè)備和管路系統(tǒng)中使用球閥，更應(yīng)注意耐火和防火。球閥的執(zhí)行器成套設(shè)備工作帶動閥體能快速的啟閉，速度可達(dá)到秒內(nèi)切斷的效果。薄型對夾球閥廠家有哪些</p><p style="text-indent:25px">球閥有哪些結(jié)構(gòu)特征？薄型對夾球閥廠家有哪些</p><p style="text-indent:25px">怎樣正確使用球閥？為了保證球閥在介質(zhì)工作壓力較低時的密封性，球體和密封座間必須形成一定的預(yù)緊比壓。在剛性密封座中，球閥工作的可靠性和使用壽命;夾于正確選擇密封座的預(yù)壓縮量。預(yù)壓縮量不足，不能保證球閥的低壓密封性:預(yù)壓縮量過大，會導(dǎo)致球體與密封座間的摩擦力矩增加，影響球閥的動作性能;并可能引起密封座的塑性變形，導(dǎo)致密封失效。對于聚四氟乙烯密封座，其預(yù)緊比壓一般應(yīng)為0. 1 PN，且不小于1.02MPa。球閥不僅結(jié)構(gòu)簡單、密封性能好，而且在一定的公稱通經(jīng)范圍內(nèi)體積較小、重量輕、材料耗用少、安裝尺寸小，并且驅(qū)動力矩小，操作簡便、易實(shí)現(xiàn)快速啟閉，是近十幾年來發(fā)展較快的閥門品種之一。薄型對夾球閥廠家有哪些</p><p
