style="font-size:16px;">由于球閥的閥座密封圈通常采用塑料制成，故在選擇球閥的結構和性能上，要考慮球閥的耐火和防火，特別是在石油、化工、冶金等部門，在易燃、易爆介質的設備和管路系統(tǒng)中使用球閥，更應注意耐火和防火。球閥分有：浮動球球閥、固定球球閥、軌道球閥、V型球閥、三通球閥、不銹鋼球閥，浮動球球閥、鑄鋼球閥、鍛鋼球閥、卸灰球閥、抗硫球閥、卡套球閥、焊接球閥。球閥與旋塞閥的工作原理一樣，都是靠旋轉閥芯來使閥門打開或關閉。球閥的閥芯是一個帶孔的球，當該孔的中心軸線與閥門進出口的中心軸線重合時，閥門打開；當旋轉該球90°，使該孔的中心軸線與閥門進出口的中心軸線垂直時，閥門關閉。球閥的使用在工程上是常見的配件，所以在選擇球閥的時候也要選擇性價比好的球閥會更好。</span>

style="font-size:16px;">球閥是一種利用球體繞閥桿的軸線旋轉90°實現(xiàn)開啟和關閉的目的閥門裝置。在具體的閥門介紹過程中，螺桿風機廠家已經(jīng)單獨介紹過止回閥、蝶閥、安全閥以及調節(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，因其結構簡單、密封性好，而且在一定的公稱通徑范圍內體積較小、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> </p><p> <span style="font-size:16px;">球閥已***應用于石油、化工、液化氣、給排水、食品、制藥、發(fā)電、造紙、城建、礦產(chǎn)、鍋爐蒸汽系統(tǒng)、市政、原子能、航空、火箭等各部門，以及人們日常生活中。球閥主要用于接通或阻斷管路介質，尤以用在要求迅速開閉的部位更佳，如應急卸荷等處。由于其具有結構簡單，零件少，重量輕，密封性能好等優(yōu)點，球閥的主要結構：主要由閥體、閥蓋、密封閥座、球體和閥桿等組成。帶孔的球體是球閥的問芯，球體受閥桿的轉動來控制啟閉，旋轉即是全程的開關。球閥可分為浮動球閥和固定球閥兩大類。浮動球閥的特點是球體可以自由浮動。根據(jù)密封座結構不同又分為固定密封座和帶活動密封座兩種。固定密封閥座的浮動球閥，結構如圖所示，在閥體內裝有兩個氟塑制成的固定密封閥座，在兩間座之間夾緊一個由碳鋼或不銹鋼制成的浮動球，球體上有圓形通孔，開后時，通道打開;當閥桿轉動時，球孔垂直于閥門的通道，靠介質的壓力將球體緊壓在后面的閥座上，保證閥門的密封。</span> 在低溫（深冷）裝置和管路系統(tǒng)中也可選用球閥。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="寧夏焊接球閥價格報價,焊接球閥"

style="font-size:16px;">固定球閥的優(yōu)勢1、密封緊急注脂救護：由于介質中的異物或火災造成閥座密封意外失效，注脂閥提供了與注脂的快速連接，方便快捷地將密封脂注入到閥座密封部位，緩解泄漏。2、可靠的閥桿密封和低操作力矩：除了設置標準密封套圈外，填料壓蓋上也設置了“O”型密封圈，雙重密封保證了閥桿密封的可靠性；增設的石墨填料和密封脂注入使火災后的閥桿泄漏降至比較低。閥桿滑動軸承和止推軸承使閥門操作輕便。3、全通徑或縮徑：可根據(jù)需要選用全通徑或縮徑結構。全通徑閥門流量孔徑與管線內徑一致，便于管線清掃。4、閥桿可加長：根據(jù)安裝或操作的需要，可對閥門閥桿進行加長。加長桿球閥，特別適用于城市煤氣等需要埋地鋪設管線的場合。加長閥桿尺寸按客戶需要確定。5、操作靈活：采用具有小摩擦系數(shù)和良好自潤滑性的閥座和閥桿軸承，**地減少了閥門的操作扭矩。因此即使在沒有提供密封潤滑脂的情形下，也能夠長期靈活自如地對閥門進行操作。</span>

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緊浮動閥座，無論閥門處于全開或全關狀態(tài)時，上下游側的閥座使流體阻斷，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時的安全性非常重要。3、防火安全結構：閥門都具備防火安全功能，其設計、制造均遵循API607和API6FA規(guī)范要求。固定球閥圖片固定球閥結構圖固定球閥。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
