style="font-size:16px;">球閥是近年來發(fā)展很快的閥種之一，可以預見隨著球閥制造技術(shù)的進步，將會得到更多的應用。球閥是閥門中的一大分支，小通徑的銅球閥使用。大通徑的法蘭球閥同樣受。球閥結(jié)構(gòu)，球閥性能，球閥原理，以及球閥分類和部分球閥產(chǎn)品，幫助您更好的進行球閥選型。球閥是旋塞閥的改進演變，屬于同一類型，它的關(guān)閉件是球體而不是旋塞。球體繞閥體中心線作90度旋轉(zhuǎn)，可啟閉閥門。球閥主要起切斷、分配和改變介質(zhì)流動方向的作用，設(shè)計成V型開口的球閥還可以做調(diào)節(jié)流量用。球閥有體積小、啟閉迅速、操作方便、安全可靠、使用</span><span style="font-size:16px;">壽命長、適用范圍廣等優(yōu)點，部分取代了閘閥、截止閥、節(jié)流閥、多通道球閥可用來實現(xiàn)介質(zhì)分配與改變介質(zhì)流向。球閥具備旋塞閥的優(yōu)點，同時克服了它的缺點，比如啟閉力矩小，密封性能好。</span>

style="font-size:16px;">球閥是由閥桿帶動作為啟閉件的球體，繞球閥軸線作旋轉(zhuǎn)運動的閥門，可以用于流體的調(diào)節(jié)和控制。球閥問世于20世紀50年代，現(xiàn)在已經(jīng)成為應用為的一大閥類。它的啟閉件是位于閥門中心處的球體，由閥桿帶動旋轉(zhuǎn)實現(xiàn)開閉操作。球閥和蝶閥、旋塞閥一樣都是四分之一轉(zhuǎn)閥，可以快速啟閉，只需要轉(zhuǎn)動90°就可以從全開到全關(guān)。球閥的球體和閥體都由金屬材料制成，如不銹鋼；閥座是較為柔軟的彈性材料，如聚四氟乙烯、氯丁橡膠等。這樣球體可以被壓在閥座上，使閥門得到良好的密封。球閥頂部與閥桿的連接處通常是矩形的，這可以讓我們在不造成球體變形的情況下施加較大的力矩，對閥門的開閉進行控制。球閥的一大優(yōu)點是閥門全開時通過閥門的流體壓降很小，幾乎不受阻礙。球閥可以分為文丘里閥、縮徑球閥</span><span style="font-size:16px;">和全通徑球閥三種，其中全通徑球閥的流道尺寸與管道內(nèi)徑相同，通過閥門的流體壓降非常小。</span> </p><p> <span style="font-size:16px;">球閥的種類，你了解多少？球閥分類方式很多，以下主要介紹四種分類方式。球閥一般是即開即關(guān)使用，密封性也沒有針閥，膜片閥好！如果用在高壓易燃易爆氣體上，氣體流速太快，有一定的風險系數(shù)，球閥通徑比較大，一般和口徑相同，所以截流比較小，通過性比較好！球閥按照操作原理一般分為手動，氣動，電動！(1).按球體結(jié)構(gòu)型式分類：浮動球式、固定球式。主要產(chǎn)品例如：法蘭浮動球閥、固定球兩片式球閥、固定球軟密封球閥、襯氟球閥、固定球不銹鋼高溫球閥等。(2).按球閥流通型式分類：直通式、三通式、四通式、五通式。主要產(chǎn)品例如：直通一片式球閥、三通法蘭球閥等。(3).按閥體裝配形式分類：一體式、二體式、三體式、上裝式。主要產(chǎn)品例如：兩體襯氟球閥、三體不銹鋼球閥、上裝式球閥等。(4).按閥體</span><span style="font-size:16px;">流道直徑分類：全通徑式、縮徑式。主要產(chǎn)品例如：全通徑法蘭球閥、縮徑式球閥等。</span> 安裝完畢后，啟動球閥開、關(guān)數(shù)次，應該動作靈活，受力均勻，球閥工作正常。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
