style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="張掖焊接球閥聯(lián)系人,焊接球閥" src="https://tyunfile.71360.com/UploadFile/gscyhwz/637316412136728515/4689270.png"></div><p> <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。浮動球球閥的結構簡單，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。這種結構，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> </p><p> <span style="font-size:16px;">球閥的工作原理是靠旋轉(zhuǎn)閥桿來使閥門暢通或閉塞。球閥開關輕便，體積小，可以做成很大口徑，密封可靠，結構簡單，維修方便，密封面與球面常在閉合狀態(tài)，不易被介質(zhì)沖蝕，在各行業(yè)得到普遍的應用。球閥和旋塞閥是同屬一個類型的閥門，只有它的關閉件是個球體，球體繞閥體中心線作旋轉(zhuǎn)來達到開啟、關閉的一種閥門。球閥的主要選用原則：石油、天然氣的輸送主管線、需要清掃管線的，又需埋設在地下的，選用全通徑、全焊接結構的球閥;埋設在地上的，選擇全通徑焊接連接或法蘭連接的球閥;支管，選用法蘭連接、焊接連接，全通徑或縮徑的球閥。一、石油、天然氣的輸送主管線，需要清掃管線的，又需埋設在地下的，選用全通徑、全焊接結構的球閥;埋設在地上的，選擇全通徑焊接連接或法蘭連接的球閥;</span><span

style="font-size:16px;">氣動球閥的特點：氣動球閥主要用于截斷或接通管路中的介質(zhì)，亦可用用于流體的調(diào)節(jié)與控制，氣動球閥與其它閥門種類相比，具有角行程輸出扭矩，開啟迅速、平穩(wěn)可靠，等以下一些優(yōu)點。1、流體阻力小、氣動球閥是所有閥門分類中流體阻力小的一種，即使是縮徑氣動球閥，其流體阻力也相當小。2、止推軸承減小閥桿磨擦力矩，可使閥桿長期操作平穩(wěn)靈活。3、閥座密封性能好，采用聚四氟乙烯等彈性材料制成的密封圈，結構易于密封，而且氣動球閥的閥封能力隨著介質(zhì)壓力的增高而增大。4、閥桿密封可靠，由于閥桿只作彷轉(zhuǎn)動運而不做升降運動，閥桿的填料密封不易破壞，且密封能力隨著介質(zhì)的壓力增高而增大。5、由于聚四氟乙烯等材料具有良好的自潤滑性，與球體的磨擦損失小，故氣動球閥的使用壽命長。6、下裝式閥桿和閥桿頭部凸階防止閥桿噴出，如火災造成閥桿密封破壞，凸階與閥體間還可形成金屬接觸，確保閥桿密封。</span>

style="font-size:16px;">不銹鋼球閥的特點有哪些？操作方便。不銹鋼球閥只需要旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動扭矩就能迅速關閉嚴密。也就是說，從全開到全關也就只需旋轉(zhuǎn)90度，是非常方便于遠距離的控制的。5.維修方便。不銹鋼球閥的閥體可以整體的，也可以是組合式的，而且整體結構也是比較簡單的。另外，其密封圈一般都是活動的，拆卸更換的時候都是比較方便的。6.可靠性強。不銹鋼球閥的密封性是非常好的，在全開或者全關的時候，球體和閥座的密封面都是與介質(zhì)隔離的，介質(zhì)通過的時候，也是不會引起閥門密封面的侵蝕，其可靠性是比較強的。不銹鋼球閥的幾個常規(guī)特點。當然，不銹鋼球閥的特點遠遠不止這些，而且隨著球閥技術的不算進步，其優(yōu)點還會逐漸增多的，我們應該不斷學習掌握這些優(yōu)點，這樣對于我們正確使用不銹</span><span
