style="text-indent:25px">電站閥門的使用要求是：性能好可靠、強度高安全、操作方便靈活、維修簡單。在熱力系統(tǒng)中我們常常遇到由于一個閥門發(fā)生故障造成整個系統(tǒng)或整個機組停止運行。尤其是母管制機組，常常因一個閥門不嚴(yán)密而無法消缺，給企業(yè)帶來不可挽回的損失。同時閥門的檢修質(zhì)量也是降低發(fā)電成本，提高機組熱效率，節(jié)能降耗的重要工作。要重視閥門的檢修質(zhì)量工作。閘閥：是作為截斷介質(zhì)使用，在全開時整個流通直通，此時介質(zhì)運行的壓力損失較小。閘閥通常適用于不需要經(jīng)常啟閉，而且保持閘板全開或全閉的工況。不適用于作為調(diào)節(jié)或節(jié)流使用。對于高速流動的介質(zhì)，閘板在局部開啟狀況下可以引起閘門的振動，而振動又可能損傷閘板和閥座的密封面，而節(jié)流會使閘板遭受介質(zhì)的沖蝕。電站閘閥主要適用于火力電站各種系統(tǒng)的管路上。</p><div

style="text-indent:25px">電站閥門的切斷主要是借助閥瓣移動實現(xiàn)的，且移動具有不同的形式，同時，閥門閥桿啟閉擁有較短的行程，因此，其切斷的可靠性較高。截止閥的閥瓣制作的材質(zhì)為鑄鋼或鍛鋼，在閥瓣打開是將會實現(xiàn)閥座與閥瓣密封面的分離，使得密封面的機械磨損相對較小，具有較好的密封性。電站閥門的密封形式有：接觸密封和非接觸密封兩類。接觸密封指的是根據(jù)密封面的互相緊靠或是接觸，嵌入從而去除間隙的接觸密封，如：閥座密封面、填料或是法蘭密封等等。這些預(yù)留的裝配間隙，無需密封力壓緊密封面的密封式非接觸密封。動密封、靜密封式根據(jù)接觸密副相對運動而劃分的。接觸型和非接觸型統(tǒng)稱為動密封。電站匣閥具有楔形密封結(jié)構(gòu)。北京鉻鉬鋼ＷＣ６電站閥生產(chǎn)廠家</p><p
