style="font-size:16px;">球閥是近年來(lái)發(fā)展很快的閥種之一，可以預(yù)見(jiàn)隨著球閥制造技術(shù)的進(jìn)步，將會(huì)得到更多的應(yīng)用。球閥是閥門(mén)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(lèi)和部分球閥產(chǎn)品，幫助您更好的進(jìn)行球閥選型。球閥是旋塞閥的改進(jìn)演變，屬于同一類(lèi)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(mén)。球閥主要起切斷、分配和改變介質(zhì)流動(dòng)方向的作用，設(shè)計(jì)成V型開(kāi)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(zhǎng)、適用范圍廣等優(yōu)點(diǎn)，部分取代了閘閥、截止閥、節(jié)流閥、多通道球閥可用來(lái)實(shí)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(diǎn)，同時(shí)克服了它的缺點(diǎn)，比如啟閉力矩小，密封性能好。</span> 球閥只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動(dòng)力矩就能關(guān)閉嚴(yán)密。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="吳忠球閥銷(xiāo)售廠家,球閥"

style="font-size:16px;">選用球閥應(yīng)遵循的原則：⑴球閥的流阻小，其通道幾乎與管道相等，故適合于對(duì)流阻比較敏感的介質(zhì)工況;⑵閥門(mén)的重量重，價(jià)格也比較高，而且閥門(mén)尺寸越大，此特點(diǎn)越明顯，所以大尺寸情況下選用球閥時(shí)，應(yīng)考慮經(jīng)濟(jì)性;⑶對(duì)于小口徑閥門(mén)，雖然軟密封球閥價(jià)格會(huì)比較便宜，但受溫度和壓力的限制，高溫高壓時(shí)不能使用;⑷固定球閥有密閉閥腔，當(dāng)用于低溫介質(zhì)工況或可能發(fā)生氣化的介質(zhì)工況條件下要有泄放裝置，或改用截止閥、蝶閥等;⑸適合用于有通球要求的管路切斷;⑹可以做襯里;⑺適宜用于壓力脈動(dòng)介質(zhì)工況和可能產(chǎn)生汽蝕的介質(zhì)工況;適宜用于高壓氧氣工況;適宜用于可能產(chǎn)生沖刷或沖刷腐蝕的介質(zhì)工況;⑻適用于多通道結(jié)構(gòu)，即一個(gè)閥門(mén)可以獲得2-4個(gè)不同的通道，可減少閥門(mén)的用量。</span> 冶金系統(tǒng)中的氧氣管路系統(tǒng)中，宜選用經(jīng)過(guò)嚴(yán)格脫脂處理，法蘭連接的固定球球閥。吳忠球閥銷(xiāo)售廠家</p><p style="text-indent:25px">球閥的一大優(yōu)點(diǎn)是閥門(mén)全開(kāi)時(shí)通過(guò)閥門(mén)的流體壓降很小，幾乎不受阻礙。吳忠球閥銷(xiāo)售廠家</p><p> <span
