style="text-indent:25px">當(dāng)球閥執(zhí)行機(jī)構(gòu)方向指示箭頭與管線平行時，閥門為開啟狀態(tài);指示箭頭與管線垂直時，閥門為關(guān)閉狀態(tài)。擁有較長的使用壽命和免維修期，將依賴以下幾個因素:正常的工作條件、保持和諧的溫度/壓力比，以及合理的腐蝕數(shù)據(jù)。注意: 球閥在關(guān)閉狀態(tài)下，閥體內(nèi)部依舊存在受壓流體；維修前，解除管線壓力并使閥門處于打開位置；維修前，斷開電源或氣源；維修前，將執(zhí)行機(jī)構(gòu)與支架脫離。使閥處于半開位置，沖洗、去除閥體內(nèi)外可能存在的危險物質(zhì)。關(guān)閉球閥，拆掉兩邊法蘭上的連接螺栓和螺母，然后將閥由管線上完全移除。</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。球閥的工藝是比較成熟嚴(yán)格的。</p><div

style="text-indent:25px">球閥的球體彈性的。球體和閥座密封圈都采用金屬材料制造，密封比壓很大，依靠介質(zhì)本身的壓力已達(dá)不到密封的要求，必須施加外力。這種閥門適用于高溫高壓介質(zhì)。彈性球體是在球體內(nèi)壁的下端開一條彈性槽，而獲得彈性。當(dāng)關(guān)閉通道時，用閥桿的楔形頭使球體漲開與閥座壓緊達(dá)到密封。在轉(zhuǎn)動球體之前先松開楔形頭，球體隨之恢復(fù)原原形，使球體與閥座之間出現(xiàn)很小的間隙，可以減少密封面的摩擦和操作扭矩。球閥長期以來受物料沖刷，產(chǎn)生摩擦，造成嚴(yán)重的沖擊磨損，不能滿足正常生產(chǎn)，同時造成了設(shè)備使用期的縮短。通常，軟密封球閥使用PTFE作為密封劑，而硬密封球閥則具有金屬表面。上海對焊球閥質(zhì)量</p><p
