style="text-indent:25px">適用場(chǎng)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(dòng)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><div

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(shí)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(huì)導(dǎo)致球體與密封座間的摩擦力矩增加，影響球閥的動(dòng)作性能;并可能引起密封座的塑性變形，導(dǎo)致密封失效。對(duì)于聚四氟乙烯密封座，其預(yù)緊比壓一般應(yīng)為0.
