style="font-size:16px;">采用縮徑式流道（無論是錐管形非均勻縮徑或均勻縮徑），其優(yōu)點是同一規(guī)格的閥門，可減少閘板的尺寸、啟閉力與力矩；缺點是流阻增加，壓降和能耗增大，所以縮孔不宜太大。對錐管形縮徑來說，閥座的內(nèi)徑與公稱通徑之比，通常取。公稱通徑小于250mm的縮徑閥門，其閥座內(nèi)徑一般比公稱通徑降低一檔；公稱通徑等于或大于300mm的縮徑閥門，其閥座內(nèi)徑一般比公稱通徑降低二檔。流道呈錐管形的即是一種非均勻縮徑，這類閥門入口端的孔徑基本上與公稱通徑相同，然后逐漸縮小，至閥座處縮小。閥關(guān)閉時，密封面可以只依靠介質(zhì)壓力來密封，即只依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的，即閥門關(guān)閉時，要依靠外力強行將閘板</span><span

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(guān)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，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(guān)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(guān)鍵的。</span> 法蘭閘閥是連接方式為法蘭的閘閥，這種連接方式比較常見。崇信閘閥生產(chǎn)廠家</p><p style="text-indent:25px">適用介質(zhì)范圍：水、蒸汽、油品、氧化性腐蝕介質(zhì)、酸、堿類煙道氣等；崇信閘閥生產(chǎn)廠家</p><p> <span style="font-size:16px;">一般用于控制流體的啟閉，流體阻力小，密封性能好，介質(zhì)的流向不受限制，開閉所需外力較小，結(jié)構(gòu)長度較短。閥桿有明桿和暗桿之分，明桿式閘閥適用于腐蝕介質(zhì)，在化工工程上基本使用明桿式閘閥。暗桿閘閥主要用于水道上，多用于低壓、無腐蝕性介質(zhì)的場合，如一些鑄鐵和銅閥門。閘板的結(jié)構(gòu)形式包括楔式閘板、平行式閘板。楔式閘板有單閘板，雙閘板之分。平行式閘板多用于油氣輸送系統(tǒng)，在化工裝置中不常用。閘閥是指關(guān)閉件（閘板）沿通道軸線的垂直方向移動的閥門，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。</span>
