style="font-size:16px;">偏心半球閥是一種比較新型的球閥類別，解決了工業(yè)生產(chǎn)中的漿狀、混流液體、灰塵等介質(zhì)在管道輸送中沉淀、易結(jié)垢、阻塞，使閥門關(guān)不嚴等問題。它有著自身結(jié)構(gòu)所獨有的一些優(yōu)越性,開關(guān)輕便,開啟時球與殼體脫離，無任何接觸，啟動扭矩小,轉(zhuǎn)動靈活。關(guān)閉時,半球與閥座的擠切作用能除去密封面上的污物，使閥門順利啟閉，安全系數(shù)高,密封性能好。密封面的偏心結(jié)構(gòu)，使球面能自動補償磨損，能保持閥門的密封，使用壽命長。閥門表面油漆，有常溫和高溫兩種。高溫用耐溫600°C的進口漆，噴涂后,高溫使用不燒漆、炭化、焦化現(xiàn)象、不變色。配以多回轉(zhuǎn)電動執(zhí)行機構(gòu)，可實現(xiàn)對介質(zhì)的調(diào)節(jié)和嚴密切斷。特別適用于鋼鐵業(yè)，鋁業(yè),有纖維、微小固體顆粒的紙漿，煤灰，石油氣等行業(yè)。</span> </p><p> <span style="font-size:16px;">啟閉無摩擦。這一功能完全解決了傳統(tǒng)閥門因密封面之間相互摩擦而影響密封的問題。上裝式結(jié)構(gòu)。對裝在管道上的閥門可直接在線檢查與維修，能有效減少裝置停車，降低成本。單閥座設(shè)計。消除了閥門中腔介質(zhì)因異常升壓而影響使用安全的問題。低扭矩設(shè)計。特殊結(jié)構(gòu)設(shè)計的閥桿，只需配一個小手把閥門就能輕松啟閉。楔形密封結(jié)構(gòu)。閥門是靠閥桿提供的機械力，將球楔壓到閥座上而密封，使閥門的密封性不受管線壓差變化的影響，在各種工況下密封性能都有可靠保證。密封面的自清潔結(jié)構(gòu)。當球體傾離閥座時，</span><span style="font-size:16px;">管線中的流體沿球體密封面成360°均勻通過，不僅消除了高速流體對閥座局部的沖刷，也沖走了密封面上的聚積物，達到自清潔的目的。</span> 偏心半球閥是一種比較新型的球閥類別.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="font-size:16px;">偏心半球閥的工作原理開啟過程在關(guān)閉位置，球體受閥桿的機械施壓作用，緊壓在閥座上。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。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)。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。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)。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°。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°。手</span><span style="font-size:16px;">輪轉(zhuǎn)動的幾圈，閥桿底部的角形平面機械地楔向壓迫球體，使其緊密地壓在閥座上，達到完全密封。</span> 偏心半球閥不允許有外漏，上、下軸端應(yīng)采用至少2道O形密封圈密封.靖遠偏心半球閥批發(fā)</p><p
