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(shí)有發(fā)生，所以，分析氧氣管道和冷門存在的隱患、危險(xiǎn)，并采取相應(yīng)的措施是至關(guān)重要的。事實(shí)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，臨夏閘閥多少錢，禁用閘閥不過是控制可燃物的一種手段而已，臨夏閘閥多少錢，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、做好靜電接地等是消除著火源。個(gè)人認(rèn)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(gè)明證，關(guān)鍵得找到原因，很多企業(yè)其實(shí)根本不管操作壓力，一律強(qiáng)行采用銅基合金閥，臨夏閘閥多少錢，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(hù)，緊繃安全這根弦才是**關(guān)鍵的。</span>

style="font-size:16px;">閘閥是指關(guān)閉件（閘板）沿通道軸線的垂直方向移動(dòng)的閥門，在管路上主要作為切斷介質(zhì)用，即全開或全關(guān)使用。一般，閘閥不可作為調(diào)節(jié)流量使用。它可以適用低溫壓也可以適用于高溫高壓，并可根據(jù)閥門的不同材質(zhì)。但閘閥一般不用于輸送泥漿等介質(zhì)的管路中。閘閥和蝶閥在管道使用中都是起開關(guān)，調(diào)節(jié)流量的作用。當(dāng)然在蝶閥和閘閥的選配過程中還是有方法的。在供水管網(wǎng)中為了降低管道覆土深度，一般口徑較大管道選配蝶閥，對覆土深度影響不大的，力求選配閘閥，但是同樣規(guī)格的閘閥價(jià)格又比蝶閥的價(jià)格高。至于口徑的分界線應(yīng)各地按具體情況考慮。從近十年使用情況而言，蝶閥出現(xiàn)的故障比閘閥高，因此在條件許可的情況下，擴(kuò)大閘閥的使用范圍是值得關(guān)注的。</span>
