style="font-size:16px;">固定球閥的特點1、雙阻塞與排放功能：固定球閥采用彈簧預(yù)緊浮動閥座，無論閥門處于全開或全關(guān)狀態(tài)時，上下游側(cè)的閥座使流體阻斷，閥體中腔滯留物通過排放閥排泄。2、自動泄壓功能：閥門體腔停留介質(zhì)溫度升高而引起異常升壓時，不需通過安全閥，而*靠閥座功能就可自動泄壓，這對保證閥門在輸送液體介質(zhì)時的安全性非常重要。3、防火安全結(jié)構(gòu)：閥門都具備防火安全功能，其設(shè)計，民勤焊接球閥銷售廠家、制造均遵循API607和API6FA規(guī)范要求。固定球閥圖片固定球閥結(jié)構(gòu)圖固定球閥。閥座密封圈常用聚四氟乙烯制成，因為其摩擦因數(shù)小，耐腐蝕性能優(yōu)異，耐溫范圍寬。也可用聚三氟氯乙烯，它比前者耐腐蝕性能稍差，但機械強度高。橡膠密封性能很好，但耐壓、耐溫性能較差，只用于溫度不高的低壓管道。大型球閥，可以制</span><span

style="font-size:16px;">球閥的特點：①球閥的比較大特點是在眾多的閥門類型中其流體阻力小，流動特性比較好。②對于要求快速啟閉的場合一般選用球閥。③與蝶閥相比，其重量較大，結(jié)構(gòu)尺寸也比較大，故不宜用于直徑太大的管道。④球閥與旋塞閥相比，開關(guān)輕便，相對體積小，所以可以制成很大口徑的閥門。⑤球閥密封可靠，結(jié)構(gòu)簡單，維修方便，密封面與球面常處于閉合狀態(tài)，不易被介質(zhì)沖蝕。⑥與蝶閥一樣，長期影響它不能在石化生產(chǎn)裝置上應(yīng)用的問題是熱脹或磨損后會造成密封不嚴。軟密封球閥雖有較好的密封性能，但當它用于易燃、易爆介質(zhì)管道上時，尚需進行火災(zāi)安全試驗和防靜電試驗。因此，石化生產(chǎn)裝置上球閥應(yīng)用不多。近年來，許多球閥生產(chǎn)廠開發(fā)出了一些新型結(jié)構(gòu)的球閥，如軌道球閥、偏心球閥等，一些球閥將閥座設(shè)置成金屬彈性閥座，使其在熱脹和磨損的情況下仍有良好的密封。因此，這些球閥已在石化生產(chǎn)裝置上開始應(yīng)用。⑦直通球閥用于截斷介質(zhì)，三通球閥可改變介質(zhì)流動方向或進行分配。文章來自網(wǎng)絡(luò)，由上海澤德水泵整理修改球閥啟閉迅速，便于實現(xiàn)事故緊急切斷。由于節(jié)流可能造成密封件或球體的損壞，一般不用球閥節(jié)流。全通道球閥不適于調(diào)節(jié)</span><span

style="font-size:16px;">球閥的工作原理：A、開啟過程1在關(guān)閉位置，球體受閥桿的機械施壓作用，緊壓在閥座上。2當逆時針轉(zhuǎn)動手輪時，閥桿則反向運動，其底部角形平面使球體脫開閥座。3閥桿繼續(xù)提升，并與閥桿螺旋槽內(nèi)的導(dǎo)銷相互作用，使球體開始無摩擦地旋轉(zhuǎn)。4直至到全開位置，閥桿提升到極限位置，球體旋轉(zhuǎn)到全開位置。B、關(guān)閉過程1關(guān)閉時，順時針旋轉(zhuǎn)手輪，閥桿開始下降并使球體離開閥座開始旋轉(zhuǎn)。2繼續(xù)旋轉(zhuǎn)手輪，閥桿受到嵌于其上螺旋槽內(nèi)的導(dǎo)銷的作用，使閥桿和球體同時旋轉(zhuǎn)90°。3快要關(guān)閉時，球體已在與閥座無接觸的情況下旋轉(zhuǎn)了90°。4手輪轉(zhuǎn)動的</span><span

style="font-size:16px;">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。這種結(jié)構(gòu)，常用于中低壓球閥。球閥的球體是固定的，受壓后不產(chǎn)生移動。固定球球閥都帶有浮動閥座，受介質(zhì)壓力后，閥座產(chǎn)生移動，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，即增強了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。</span>
