對焊式高壓截止閥的結(jié)構(gòu)長度按E101的規(guī)定。閥體焊接坡口按ANSI B16.25的規(guī)定或按用戶提供的尺寸。

對焊式高壓截止閥產(chǎn)品介紹：
電站截止閥也稱電站截止閥，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(shè)計，壓力越高，密封越可靠。由于性能技術(shù)特性、工況的特殊使產(chǎn)品也形成了其他產(chǎn)品所替代不了的特點。制造驗收技術(shù)條件按日本火力發(fā)電用閥門標(biāo)準(zhǔn)E101的規(guī)定。磅級電站截止閥的結(jié)構(gòu)長度按E101的規(guī)定。閥體焊接坡口按ANSI B16.25的規(guī)定或按用戶提供的尺寸。閥蓋填料函嘗試合理，填料加緩蝕劑，密封可靠，開關(guān)平穩(wěn)。閥門具有上密封結(jié)構(gòu),保證閥門開啟運行時閥桿處不會外漏。

對焊式高壓截止閥應(yīng)用范圍：
電站截止閥適用于Class1500～3500Lb、工作溫度-29～570℃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(zhì)。適用介質(zhì)為：水、油品、蒸汽等非腐蝕性介質(zhì)。

對焊式高壓截止閥結(jié)構(gòu)特點：
1.產(chǎn)品設(shè)計制造按ASME B16.34、E101標(biāo)準(zhǔn)，可與進口設(shè)備配備使用。
2.閥門中腔采用壓力自緊式密封結(jié)構(gòu)，內(nèi)腔壓力越高密封性能越好。
3.支管兩端為對焊連接，適應(yīng)不同的接管要求。
4.閥瓣、閥座的密封面采用slite 司太立鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫，抗擦傷性能好、使用壽命長。
5.閥蓋填料函嘗試合理,填料加緩蝕劑,密封可靠,開關(guān)平穩(wěn)。
6.閥門具有上密封結(jié)構(gòu),保證閥門開啟運行時閥桿處不會外漏。
7.電動截止閥的開啟和關(guān)閉由電動裝置來控制，電動裝置分別配有電機、減速器、轉(zhuǎn)矩控制機構(gòu)，現(xiàn)場操作機構(gòu)，手動、電動切換機構(gòu)。除就地操作外，還可進行遠距離操作。
