style="text-indent:25px">氣動(dòng)球閥是球閥配上氣動(dòng)執(zhí)行器，氣動(dòng)執(zhí)行器的執(zhí)行速度相對(duì)較快，較快的開(kāi)關(guān)速度0.05秒/次，所以通常也叫氣動(dòng)快速切斷球閥。那么氣動(dòng)球閥在選擇上需要考慮到什么因素呢？為避免氣動(dòng)球閥內(nèi)件（閥芯、閥座）表面的磨損、沖蝕及氣蝕，高溫情況下要考慮材料的熱硬度，防止金屬硬度變化。在高壓差***體的大部分能量集中于閥內(nèi)件進(jìn)行釋放，對(duì)閥門(mén)內(nèi)件有超負(fù)載的可能，而高溫下，大部分材料的機(jī)械性能變差，材料變軟，極大影響了閥內(nèi)件的使用壽命。而相同的介質(zhì)，在高溫狀況下，其分子的活動(dòng)性相對(duì)活躍，某些具有一般腐蝕性的介質(zhì)可能對(duì)閥體及閥內(nèi)件金屬材質(zhì)帶來(lái)嚴(yán)重的腐蝕破壞，介質(zhì)以高速的離子狀態(tài)滲入金屬內(nèi)部，使材料的特性發(fā)生改變，如熱膨脹性、晶間腐蝕等，因此，對(duì)材料的選擇，除了性?xún)r(jià)比之外，還應(yīng)考慮多因素下所產(chǎn)生的失效性。因此，應(yīng)正確選擇合適的材料，延長(zhǎng)氣動(dòng)球閥的使用壽命。另外，還要考慮高溫時(shí)效對(duì)材料物理性能的影響，如韌性和晶間腐蝕的變化。當(dāng)使用溫度達(dá)到或超過(guò)熱處理溫度時(shí)，閥內(nèi)件會(huì)產(chǎn)生退火，硬度降低等問(wèn)題，為防止材料硬度發(fā)生變化，較高溫度極限的選擇必須在一個(gè)安全的范圍內(nèi)。</p><p
