style="text-indent:25px">球閥的球體是浮動(dòng)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(dòng)球球閥的結(jié)構(gòu)簡(jiǎn)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，在受到較高壓力沖擊時(shí)，球體可能會(huì)發(fā)生偏移。這種結(jié)構(gòu)，一般用于中低壓球閥。球閥的主要特點(diǎn)是本身結(jié)構(gòu)緊湊，密封可靠，結(jié)構(gòu)簡(jiǎn)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，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(zhì)，而且還適用于工作條件惡劣的介質(zhì)，如氧氣、過氧化氫、甲烷和乙烯等，在各行業(yè)得到廣泛的應(yīng)用。球閥閥體可以是整體的，也可以是組合式的。</p><p style="text-indent:25px">卸灰球閥是由截止閥演變而來。它具有相同的旋轉(zhuǎn)90度提動(dòng)作，不同的是旋塞體是球體，有圓形通孔或通道通過其軸線。卸灰球閥的球面和通道口的比例應(yīng)該是這樣的，即當(dāng)球旋轉(zhuǎn)90度時(shí)，在進(jìn)、出口處應(yīng)全部呈現(xiàn)球面，從而截?cái)嗔鲃?dòng)。卸灰球閥的安裝：1)、取掉法蘭端兩邊的保護(hù)蓋，在閥完全打開的狀態(tài)下進(jìn)行沖洗清潔。2）、安裝前應(yīng)按規(guī)定的信號(hào)（電或氣）進(jìn)行整機(jī)測(cè)試（防止因運(yùn)輸產(chǎn)生振動(dòng)影響使用性能），合格后方可上線安裝（接線按電動(dòng)執(zhí)行機(jī)構(gòu)線路圖）。3)、準(zhǔn)備與管道連接前，須沖洗和去除干凈管道中殘存的雜質(zhì)（這些物質(zhì)可能會(huì)損壞閥座和球）。4)、在安裝期間，請(qǐng)不要用閥的執(zhí)行機(jī)構(gòu)部分作為起重的吊裝點(diǎn)，以避免損壞執(zhí)行機(jī)構(gòu)及附件。.5)、本類閥應(yīng)安裝在管道的水平方向或垂直方向。6)、安裝點(diǎn)附近的管道不可有低垂或者承受外力的現(xiàn)象，可以用管道支架或者支撐物來消除管線的偏離。7)、與管道連接后，請(qǐng)用規(guī)定的扭矩交叉鎖緊法蘭連接螺栓。浙江錳特閥門有限公司鍛鋼球閥設(shè)備值得用戶放心。</p><p
