style="font-size:16px;">閘閥的啟閉件是閘板，閘板的運(yùn)動(dòng)方向與流體方向相垂直，閘閥只能作全開(kāi)和全關(guān),不能作調(diào)節(jié)和節(jié)流。閘板有兩個(gè)密封面,常用的模式閘板閥的兩個(gè)密封面形成楔形、楔形角隨閥門參數(shù)而異,通常為50,介質(zhì)溫度不高時(shí)為2°52'。楔式閘閥的閘板可以做成一個(gè)整體，叫做剛性閘板;也可以做成能產(chǎn)生微量變形的閘板,以改善其工藝性,彌補(bǔ)密封面角度在加工過(guò)程中產(chǎn)生的偏差,這種閘板叫做彈性閘板。閘閥的種類,按密封面配置可分為楔式閘板式閘閥和平行閘板式閘閥,楔式閘板式閘閥又可分為:單閘板式、雙閘板式和彈性閘板式;平行閘板式閘閥可分為單閘板式和雙閘板式。按閥桿的螺紋位置劃分，可分為明桿閘閥和暗桿閘閥兩種。閘閥關(guān)閉時(shí),密封面可以只依靠介質(zhì)壓力來(lái)密封,即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來(lái)保證密封面的密封，這就是自密封。大部分閘閥是采用強(qiáng)制密封的,即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座,以保證密封面的密封性。</span> </p><p> <span style="font-size:16px;">近年來(lái)，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(zhǎng)，分布廣，再加上急開(kāi)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(kāi)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(guò)是控制可燃物的一種手段而已，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(wèn)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，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>
