電動直流對焊截止閥概述
      截止閥具有結構緊湊，密封面不易磨損、擦傷；密封性能好，制造與維修方便；啟閉時閥瓣行程小，啟閉時間短；閥門高度小，工藝性能好和適用范圍廣等特點；是一種廣泛使用的截斷閥，用于截斷或接通管路中的介質，一般不用于調節(jié)流量。引進磅級高壓電站截止閥適應于ANSI CLASS 1500-3500LB，工作-29～570度的石油，化工，火力電站等各種工況的管路上，切斷或接通介質．適用介質：水石油，蒸汽等。磅級電站截止閥也稱電站截止閥，電站截止閥主要適用于火力電站各種系統(tǒng)的管路上，切斷或接通管路介質。電站截止閥適用介質∶水、蒸氣等非腐蝕性介質。電站截止閥與其他截止閥產(chǎn)品相比的特點是高溫高壓，*的自密封設計，壓力越高，密封越可靠。
 
電動直流對焊截止閥結構優(yōu)勢與特點：
1，磅級引進高壓電站截止閥產(chǎn)品設計制造按ANSIB16.34,E101標準，可與進口設備直接配套使用．
2，閥門中腔采用自緊式密封結構，內腔壓力越高密封性能越好，支管兩端為對焊接，適應不同的接管要求．
3，引進磅級高壓電站截止閥的閥體，閥蓋有足夠的強度和剛性．通道流暢，流體阻力小．
4，閥瓣和閥座的密封面采用司太立（SLITE）鈷革硬質合金堆焊而成，密封面硬度高，耐磨，耐高溫，耐腐蝕，抗擦傷性能好，使用壽命長．
5，閥桿經(jīng)調質和表面氮化處理，有良好的抗腐蝕性和抗擦傷性．
6，閥蓋填料函深度合理，填料加緩蝕劑，密封可靠，開關平穩(wěn)．
7，級高壓電站截止閥門具有上密封結構，保證閥門開啟運行時不經(jīng)閥桿外漏．
8，電動電站截止閥的開啟和關閉由電動裝備來控制，電動裝置分別配有電機，減速機，轉矩控制機構，現(xiàn)場操作機構，手動，電動切換機構．除就地操作外，還可進行遠距離操作．

用途
焊接連接的截止閥適用于公稱壓力PN20～32MPa及P54/100V-P57/170V ，工作溫度≤540℃（其中P57/170V工作溫度為570℃）的石油 、化工 、水力 、火力電站各種系統(tǒng)的管路中，切斷或接通管路介質,，適用介質為：水、油品、蒸汽等。操作方式有：手動、齒輪傳動、電動等。

    是采用高品質截止閥和高精度電動執(zhí)行器組成。結構合理，性能優(yōu)良，造型美觀，適用的壓力范圍廣，主要用來接通或截斷管路中的介質，具有耐磨、耐高溫，抗擦傷性能好、使用壽命長等優(yōu)點。據(jù)我集團各產(chǎn)品生產(chǎn)工藝的特點，針對各種介質，作閥門選用的一般要求如下： 截止閥具有結構緊湊，密封面不易磨損、擦傷；密封性能好，制造與維修方便；啟閉時閥瓣行程小，啟閉時間短；閥門高度小，工藝性能好和適用范圍廣等特點；是一種廣泛使用的截斷閥，用于截斷或接通管路中的介質，一般不用于調節(jié)流量。 用途 焊接連接的截止閥適用于公稱壓力PN20～32MPa及P54/100V-P57/170V ，工作溫度≤540℃（其中P57/170V工作溫度為570℃）的石油 、化工 、水力 、火力電站各種系統(tǒng)的管路中，切斷或接通管路介質,，適用介質為：水、油品、蒸汽等。操作方式有：手動、齒輪傳動、電動等。
