style="font-size:16px;">選擇球閥的時候要注意以下幾點：使用壽命長：已應用于石油、化工、發(fā)電、造紙、原子能、航空、火箭等各部門，以及人們日常生活中。氣動球閥結構簡單緊湊，密封可靠，維修方便，密封面與球面常在閉合狀態(tài)，不易被介質沖蝕，易于操作和維修，適用于水、溶劑、酸和天然氣等一般工作介質，主要用于截斷或接通管路中的介質，亦可用于流體的調節(jié)與控制。氣動球閥與其它種類閥門相比，具有角行程輸出扭矩，開啟迅速、平穩(wěn)可靠，適用***，氣動閥門的原理：即以壓縮空氣（空氣壓縮機）為動力來源，通過電磁閥轉換驅動氣動執(zhí)行器，氣動執(zhí)行器驅動閥門，實現閥門開關。蒸汽閥門：由壓縮空氣驅動的閥門。在目前市場經濟環(huán)境下，在購買氣動閥門時只規(guī)定規(guī)格、類別和壓力以滿足采購要求的做法并不完善，因為氣動閥門制造商都是以產品競爭為目的統(tǒng)一設計氣動閥門的理念下。不同的創(chuàng)新，形成了自己的企業(yè)標準和產品個性。因此，有必要在購買氣動閥門時提出詳細的技術要求，并作為氣</span><span style="font-size:16px;">動閥門采購合同的附件與制造商取得一致。</span> </p><p> <span style="font-size:16px;">球閥球體型式(1).浮動球與固定球結構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，因此具有結構簡單，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，但是結構復雜，工藝繁瑣，價格高。固定球的幾種結構型式和性能：①進口端密封：閥門關閉時填料和大部分閥體不受內壓，缺點是閥體轉矩大且閥桿軸承受壓力大。②出口端密封：如果進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閉時內腔都處于介質壓力作用下。③前后雙密封：兩閥座前后端**切斷，關閉時進出口端同時受壓，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部沉積物，但是中腔有介質且應設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。但是結構復雜。⑤軌道式球閥：閥桿上有導軌和導向銷的相互作用，但閥座結構單向密封，適用于惡劣</span><span

style="font-size:16px;">電磁球閥以電磁鐵的推力為動力，推動鋼球閥芯運動來實現油路通斷和切換的。電磁球閥的密封性能好，反應速度快，換向頻率高，對工作介質粘度的適應范圍廣；沒有滑閥所需承受的液壓卡緊力，換向和復位所需的力量小，可用于高壓系統(tǒng)；靠球式閥芯密封換向，抗污染能力強。但目前電磁球閥可供選用的機能少，規(guī)格較小。電磁球閥主要應用在高壓小流量系統(tǒng)中，或在大流量系統(tǒng)中作先導控制元件使用。電磁球閥的使用過程與選擇球閥密切相關。所以在選購球閥的時候要注意球閥的性能與型號。對球閥的質量也要多多注意，不然在后期的使用中會產生很多的問題，也會浪費很多的時間。所以為了使用方便，在前期的過程中要注意選擇好球閥的品質與性能。把球閥的安裝規(guī)范要多多注意。</span>
