style="text-indent:25px">氣動(dòng)閥門常見的問題有哪些？氣動(dòng)止回閥</p><p style="text-indent:25px">氣動(dòng)閥門是由旋塞閥演變而來。它具有相同的旋轉(zhuǎn)90度動(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。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)。本類閥門在管道中可任意位置安裝。氣動(dòng)球閥只需要用氣動(dòng)執(zhí)行器用氣源旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動(dòng)力矩就能關(guān)閉嚴(yán)密。完全平等的閥體內(nèi)腔為介質(zhì)提供了阻力很小、直通的流道。通常認(rèn)為球閥較適宜直接做開閉使用。球閥的主要特點(diǎn)是本身結(jié)構(gòu)緊湊，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。球閥閥體可以是整體的，也可以是組合式的。氣動(dòng)球閥克服了現(xiàn)有氣動(dòng)球閥在現(xiàn)有的工作環(huán)境下使用壽命短、易損壞的缺點(diǎn),氣動(dòng)球閥包括閥座和閥體,產(chǎn)品的閥座布置在閥體中,閥座由對位聚苯制成。氣動(dòng)止回閥</p><p
