</p><p> <span style="font-size:16px;">浮動(dòng)球閥適用于：化工，石油，天然氣，冶金，等行業(yè)及含硫化氫介質(zhì)，雜質(zhì)多，腐蝕嚴(yán)重的天然氣長(zhǎng)輸管線(xiàn)。浮動(dòng)球閥的主要結(jié)構(gòu)特點(diǎn)為：1.閥門(mén)設(shè)有開(kāi)、關(guān)位置指示;2.鎖定裝置;3.閥桿防飛結(jié)構(gòu);4.防靜電裝置;5.防火結(jié)構(gòu);6.獨(dú)特閥座密封結(jié)構(gòu);7.中法蘭(閥體與左體連接部)無(wú)外漏結(jié)構(gòu)。球體有一個(gè)稱(chēng)為固定球閥的固定軸球閥。固定球閥主要用于高壓大口徑。根據(jù)閥座密封圈的不同安裝情況，固定球閥可以有兩種結(jié)構(gòu)：密封在球體前面的閥座和密封在球體內(nèi)的閥座。球閥是生產(chǎn)生活中常用的閥門(mén)之一；主要用于食品、化工、石油、電力等行業(yè)。球閥在管路中主</span><span

style="font-size:16px;">球閥適用場(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(lái)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(mén)，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。通常，在雙位調(diào)節(jié)、密封性能?chē)?yán)格、泥漿、磨損、縮口通道、啟閉動(dòng)作迅速（1/4轉(zhuǎn)啟閉）、高壓截止（壓差大）、低噪聲、有氣穴和氣化現(xiàn)象、向大</span><span
