style="font-size:16px;">為了滿足高溫、高壓、強(qiáng)沖蝕、長壽命等工業(yè)應(yīng)用的使用要求，近十幾年來，金屬密封球閥得到了很大的發(fā)展。尤其在工業(yè)發(fā)達(dá)的國家，如美國、意大利、德國、西班牙、荷蘭等，對(duì)球閥的結(jié)構(gòu)不斷改進(jìn)，出現(xiàn)全焊接閥體直埋式球閥、升降式球閥、使球閥在長輸管線、煉油裝置等工業(yè)領(lǐng)域的應(yīng)用，出現(xiàn)了大口徑（3050mm）、高壓力（70MPa）、寬溫度范圍（-196~815℃）的球閥，從而使球閥的技術(shù)達(dá)到一個(gè)全新的水平。球閥是由旋塞閥演變而來，它的啟閉件是一個(gè)球體，利用球體繞閥桿的軸線旋轉(zhuǎn)90°實(shí)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(dòng)方向，設(shè)計(jì)成V形開口的球閥還具有良好的流量調(diào)節(jié)功能。球閥只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動(dòng)力矩就能關(guān)閉嚴(yán)密。完全平等的閥體內(nèi)腔為介質(zhì)提供了阻力很小、直通的流道。通常認(rèn)為球閥**適宜直接做開閉使用，但近來的發(fā)展已將球閥設(shè)計(jì)成使它具有節(jié)流和控制流量之用。在各行業(yè)得到***的應(yīng)用。球閥閥體可以是</span><span style="font-size:16px;">整體的，也可以是組合式的。</span> </p><p> <span style="font-size:16px;">球閥的球體是固定的，受壓后不產(chǎn)生移動(dòng)。固定球閥都帶有浮動(dòng)閥座，受介質(zhì)壓力后，閥座產(chǎn)生移動(dòng)，使密封圈緊壓在球體上，以保證密封。通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門。為了減少球閥的操作扭矩和增加密封的可靠程度，近年來又出現(xiàn)了油封球閥，既在密封面間壓注特制的潤滑油，以形成一層油膜，即增強(qiáng)了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。球閥的球體是彈性的。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(shí)，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(dòng)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。</span>
