截止閥（Globe Valve）的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。電動(dòng)截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。 電動(dòng)截止閥結(jié)構(gòu)圖 主要特點(diǎn)及用途 Chief features and usages |
| 1、結(jié)構(gòu)緊湊、設(shè)計(jì)合理，閥門剛性好，通道流暢，流阻系數(shù)小。 |
| 2、密封面采用不銹鋼和硬質(zhì)合金，使用壽命長 |
| 3、采用柔性石墨填料、密封可靠、操作輕便靈活 |
| 4、驅(qū)動(dòng)方式分手動(dòng)、電動(dòng)、氣動(dòng)、齒輪傳功，結(jié)構(gòu)型式：彈性楔式單閘板、剛性楔式單閘板和雙閘板型式。 |
| 5、廣泛適用于石油化工，火力發(fā)電廠等油品、水蒸汽管路上作接通或截?cái)喙苈分薪橘|(zhì)的啟閉裝置。 |
| 1、Compact structure,neasonnable design,good rigidity,smooth channel,small coefficient of flow resistance. |
| 2、The sealing face uses stainless steel and carbide alloy and is of long duration |
| 3、Using flexible graphite fillings,reliable sealing,light and nimble operation |
| 4、Four driving ways,manually,electrically,air-ioerating and gear-driving,structure type,elastic wedge type with single gate board,right rigi-dwedge type with single or dual-gate board. |
| 5、Widely used as the device of open or close to connect or cut off the medium inside of the pioeline of water,steam or oil goods in steam power plants |
