style="font-size:16px;">普通閥座的特點是在預(yù)緊力或流體壓力作用下閥座與球體壓緊，并使閥座材料產(chǎn)生彈塑性變形而達到密封，其密封效果取決于閥座在流體壓力或預(yù)緊力的作用下補償球體圓度和表面微觀不平度的能力。因此，閥座與球體之間必須具有足夠大的密封比壓。彈性閥座借助于彈性元件，如金屬彈簧架和彈簧等，在預(yù)緊力或流體壓力下產(chǎn)生彈性變形，以補償溫差、壓力和磨損等外界條件變化對球體密封性能的影響。彈簧組合式閥座是沿閥門通道橫向截面圓周均布一組壓縮彈簧或*用一只碟型彈簧的推力，始終保持閥座壓緊球體而達到預(yù)緊狀態(tài)?；钊介y座是依靠進口介質(zhì)壓力產(chǎn)生密封力，閥座被推動壓緊球體，密封圈產(chǎn)生彈塑性變形實現(xiàn)密封。截斷泄放閥座在閥腔內(nèi)的壓力異常升高到大于下游端壓力時，形成的壓差作用產(chǎn)生向外推</span><span

style="font-size:16px;">球閥適用于低溫、高壓、粘度大的介質(zhì)。大多數(shù)球閥可用于帶懸浮固體顆粒的介質(zhì)中，依據(jù)密封的材料要求也可用于粉狀和顆粒狀的介質(zhì)；全通道球閥不適用于流量調(diào)節(jié)，但適用于要求快速啟閉的場合，便于實現(xiàn)事故緊急切斷；通常在密封性能嚴格、磨損、縮口通道、啟閉動作迅速、高壓截止（壓差大）、低噪音、有氣化現(xiàn)象、操作力矩小、流體阻力小的管路中，推薦使用球閥；球閥適用于輕型結(jié)構(gòu)、低壓截止、腐蝕性介質(zhì)中；球閥還是低溫、深冷介質(zhì)的**理想閥門，低溫介質(zhì)的管路系統(tǒng)和裝置上，宜選用加上閥蓋的低溫球閥；選用浮動球球閥時其閥座材料應(yīng)承接球體和工作介質(zhì)的載荷，大口徑的球閥在操作時需要較大的力，DN≥200mm的球閥應(yīng)選用蝸輪傳動形式；固定球球閥適用于較大口徑及壓力較高的場合；</span><span style="font-size:16px;">另外，用于工藝劇毒物料、可燃介質(zhì)管道的球閥，應(yīng)具有防火、防靜電結(jié)構(gòu)。</span> </p><p> <span style="font-size:16px;">球閥只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動力矩就能關(guān)閉嚴密。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。球閥閥體可以是整體的，也可以是組合式的。球閥的分類：球閥按結(jié)構(gòu)形式可分為：浮動球閥、固定球閥、彈性球閥和油封球閥；按通道可分為直能式球閥、角式球閥和三通式球閥等，三通式又可分為T形和L形兩種。按連接方工可分為螺紋式連接球閥、法蘭連接球閥和焊接式球閥三種。球閥的球體是浮動的，在介質(zhì)壓力作用下，球體能產(chǎn)生一定的位移并緊壓在出口端的密封面上，保證出口端密封。浮動球閥的結(jié)構(gòu)簡單，密封性好，但球體承受工作介質(zhì)的載荷全部傳給了出口密封圈，因此要考慮密封圈材料能否經(jīng)受得住球體介質(zhì)的工作載荷，在受到較高壓力沖擊時，球體可能會發(fā)生偏移。這種結(jié)構(gòu)，一般用于中低壓球閥。</span>
