style="font-size:16px;">球閥球體型式(1).浮動球與固定球結(jié)構(gòu)型式和性能比較圖如圖所示。浮動球可以自由地在閥座中浮動，因此具有結(jié)構(gòu)簡單，重量輕等優(yōu)點，但是必須要有足夠的輕度來承受高的密封比壓、以及操作扭矩大、不適用高壓及大口徑閥門。固定球的閥球不會移動，整體渾然天成，因此扭矩小，密封性能好，適用大口徑高壓環(huán)境，但是結(jié)構(gòu)復(fù)雜，工藝繁瑣，價格高。固定球的幾種結(jié)構(gòu)型式和性能：①進(jìn)口端密封：閥門關(guān)閉時填料和大部分閥體不受內(nèi)壓，缺點是閥體轉(zhuǎn)矩大且閥桿軸承受壓力大。②出口端密封：如果進(jìn)口端密封失敗可以使用出口端密封從而提高閥門密封可靠性，減小球體支撐軸的載荷，適用于高壓工況，但是流通截面積減少且關(guān)閉時內(nèi)腔都處于介質(zhì)壓力作用下。③前后雙密封：兩閥座前后端**切斷，關(guān)閉時進(jìn)出口端同時受壓，閥門中腔和兩端通道可以被相互切斷，適用于高要求工況，可以通過泄壓閥沖洗閥體內(nèi)部沉積物，但是中腔有介質(zhì)且應(yīng)設(shè)置防止異常升壓裝置。④油封式：在密封面間壓注特制的潤滑油，形成一層油膜，增強密封性能且減小扭矩摩擦。但是結(jié)構(gòu)復(fù)雜，景泰焊接球閥銷售廠家。⑤軌道式球閥：閥桿上有導(dǎo)軌和導(dǎo)向銷的相互作用，但閥座結(jié)構(gòu)單向密封，適用于惡劣</span><span

style="font-size:16px;">球閥的結(jié)構(gòu)大體上主要由閥體、球體、閥座密封圈、閥桿以及驅(qū)動裝置等組成：由于它的啟閉件是球體，在管路中截流時，介質(zhì)容易對球體的邊緣造成沖蝕，所以球閥只做全開或全關(guān)，同時它還具有以下特點：1、不受安裝方向的限制，介質(zhì)的流向可任意。流體阻力小，全通徑的球閥基本沒有流阻。通道平整光滑，不易沉積介質(zhì)。2、密封性能好。球閥有兩個密封面，閥座密封圈一般采用聚四氟乙烯等材料，密封性好，而且球閥的密封力隨著介質(zhì)壓力的增加而增大，高真空及高壓力均可使用。3、球閥啟閉迅速、輕便。從全開到全關(guān)只要旋轉(zhuǎn)90°。4、閥桿密封可靠，球閥啟閉時閥桿只做旋轉(zhuǎn)運動，因此閥桿的填料密封不易被破壞，其密封力也會隨著介質(zhì)壓力的增加而增大。5、球閥的啟閉只做90°轉(zhuǎn)動，容易實現(xiàn)自動化控制和遠(yuǎn)距</span><span

style="font-size:16px;">球閥是一種利用球體繞閥桿的軸線旋轉(zhuǎn)90°實現(xiàn)開啟和關(guān)閉的目的閥門裝置。在具體的閥門介紹過程中，螺桿風(fēng)機廠家已經(jīng)單獨介紹過止回閥、蝶閥、安全閥以及調(diào)節(jié)閥等，***我們再來了解下常見的球閥。球閥由旋塞演變而來，啟閉件是一個球體，因其結(jié)構(gòu)簡單、密封性好，而且在一定的公稱通徑范圍內(nèi)體積較小、重量輕、材料損耗少，所以是一種實用性很強、使用很的閥門品種，用于切斷或改變介質(zhì)流量。其公稱通徑從8mm——1200mm，公稱壓力從真空到42MPa，工作溫度從-204℃到815℃。密封性能好；由于硬密封球閥的密封是采用人工研磨，直到閥芯與密封圈完全吻合才能使用。所以他的密封性能是可靠的。開關(guān)輕；由于硬密封球閥的密封圈底部采用彈簧使密封圈與閥芯緊緊抱在一起。</span>
