style="font-size:16px;">近年來，隨著氧氣用量的增加，用氧大戶都采用氧氣管道輸送。由于管路長，分布廣，再加上急開或速閉閥門，造成氧氣管道和閥門燃燒的事故時有發(fā)生，所以，分析氧氣管道和冷門存在的隱患、危險，并采取相應的措施是至關重要的。事實上很多未采用閘閥的氧氣管道一樣出現(xiàn)事故，一般都出現(xiàn)在閥門兩側(cè)壓差較大，閥門開啟較快的瞬間，多次事故也表明，著火源和可燃物是終的原因，禁用閘閥不過是控制可燃物的一種手段而已，臨夏閘閥聯(lián)系方式，和定期鐵銹、脫脂、禁油等手段的目的都是一樣的，至于控制流速，臨夏閘閥聯(lián)系方式、做好靜電接地等是消除著火源，臨夏閘閥聯(lián)系方式。個人認為閥門材質(zhì)是因素，在氫氣管道上也出現(xiàn)類似的問題，新規(guī)范已經(jīng)將“禁用閘閥”的字眼去掉了，就是個明證，關鍵得找到原因，很多企業(yè)其實根本不管操作壓力，一律強行采用銅基合金閥，但一樣有的事故出現(xiàn)，所以控制著火源和可燃物，精心維護，緊繃安全這根弦才是**關鍵的。</span>

style="font-size:16px;">彈性閘板閘閥它是楔式單閘板閥的特殊形式。與楔式閘閥比較，在高溫時，密封性能好，閘板受熱后不易被卡住；適用于蒸汽、高溫油品及油氣介質(zhì)，并適用于開關頻繁的部位；不適用于易結(jié)焦的介質(zhì)。雙閘板閘閥密封性能較楔式閘閥好，當密封面的傾斜角度和閥座配合不十分準確時，仍具有較好的密封性能；閘閥閥體的流道可分為，全通徑式和縮徑式兩種。流道孔徑與閥門公稱通經(jīng)，基本相同的為全通徑式；流通孔徑比閥門公稱通經(jīng)小的稱為縮徑式。閘板密封面磨損后，將球面頂心底部的金屬墊更換后即可使用，一般不必堆焊和研磨密封面；適用于蒸汽、高溫油品及油氣介質(zhì)，并適用于開關頻繁的部位；不適用于易結(jié)焦的介質(zhì)。平行式閘閥密封性能較其它形式的閘閥要差；適用于溫度和壓力較低的介質(zhì)；閘板及閥座的密封面的加工及檢修比其他形式的閘閥簡單。</span>
