style="text-indent:25px">真空閥門毛坯的制造工藝及檢驗：真空閥門使用在流體管路上，它本身承受各種溫度、壓力的介質(zhì)的沖刷和腐蝕，若毛坯存在極小的缺陷也會發(fā)生滲漏，而造成介質(zhì)的損失和浪費。當輸送有毒有害、易燃、易爆或放射性介質(zhì)時，閥門滲漏往往會引起中毒火災(zāi)或污染等重大事故，并迫使系統(tǒng)或工廠停產(chǎn)。為了確保閥門的安全可靠性，除了在出廠前以公稱壓力的1.25～1.5倍的試驗壓力對閥門進行強度試驗外，對毛坯的外部質(zhì)量和內(nèi)部質(zhì)量要求也很嚴格。真空閥門的鑄件毛坯是結(jié)構(gòu)較復雜的薄壁殼體件，鑄件要求表面光潔、鑄字清晰，特別是要有致密的組織，不得有氣孔、縮孔、疏松、裂紋和包砂等缺陷。為了滿足上述要求，鑄造時需采取一系列工藝措施，如選用高耐火度的造型材料并控制型砂水分，造型時應(yīng)分層打?qū)嵰员ＷC砂型硬度，采用合理的澆冒口系統(tǒng)及嚴格控制澆注速度和溫度等?？傊Ｓ捎诩夹g(shù)要求較高，閥門毛坯的鑄造工藝比一般鑄件復雜。真空閥門毛坯除進行尺寸、位置精度及外觀檢查外，有的還要進行金相組織、化學成分、力學性能、耐腐蝕性能和無損探傷等多項檢驗，以排除導致閥門殼體滲漏的缺陷。濟南高壓真空閥門真空閥門缺件后，不能拆動補西，應(yīng)配齊閥件，為下步運用發(fā)明良好條件，保證閥門處于完好狀況。</p><div
