style="font-size:16px;">球閥是一種利用球體繞閥桿的軸線旋轉(zhuǎn)90°實(shí)現(xiàn)開啟和關(guān)閉的目的閥門裝置。在具體的閥門介紹過程中，螺桿風(fēng)機(jī)廠家已經(jīng)單獨(dú)介紹過止回閥、蝶閥、安全閥以及調(diào)節(jié)閥等，***我們再來了解下常見的球閥。球閥由旋塞演變而來，啟閉件是一個(gè)球體，因其結(jié)構(gòu)簡單、密封性好，而且在一定的公稱通徑范圍內(nèi)體積較小、重量輕、材料損耗少，所以是一種實(shí)用性很強(qiáng)、使用很的閥門品種，用于切斷或改變介質(zhì)流量。其公稱通徑從8mm——1200mm，公稱壓力從真空到42MPa，工作溫度從-204℃到815℃。密封性能好；由于硬密封球閥的密封是采用人工研磨，直到閥芯與密封圈完全吻合才能使用。所以他的密封性能是可靠的。開關(guān)輕；由于硬密封球閥的密封圈底部采用彈簧使密封圈與閥芯緊緊抱在一起。</span> </p><p> <span style="font-size:16px;">氣動(dòng)球閥的優(yōu)點(diǎn)：球閥閥桿的密封也比較靠譜，因?yàn)殚y桿并不做升降運(yùn)動(dòng)，而防轉(zhuǎn)動(dòng)運(yùn)以及填料密封不容易遭到破壞;針對(duì)止推軸承，能發(fā)揮減小閥桿摩擦力據(jù)的效果，即便使用了很長一段時(shí)間，仍然能靈活操縱閥桿;防靜電功能不容忽視。在球體、閥體與閥桿之間，約西流體設(shè)計(jì)師會(huì)放入彈簧，可以在閥門啟閉過程中安全導(dǎo)出所產(chǎn)生的靜電;下裝式閥桿，可有效防止閥桿的噴出，比如碰到火災(zāi)等問題，很容易破壞密封性，而這一方法可在閥體間有效形成金屬接觸，確保不泄漏。氣動(dòng)球閥和普通球閥的區(qū)別也有好很多不同的地方，比普通球閥的性能要高，質(zhì)量要好。所以在選購的時(shí)候一般都會(huì)選擇氣動(dòng)球閥。氣動(dòng)球閥的優(yōu)勢出來上面幾點(diǎn)以外，還有很多功能。使用周期長、耐腐蝕性能強(qiáng)。</span>
