style="text-indent:25px">電站焊接截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿閥座的中心線作直線運(yùn)動。閥桿的運(yùn)動形式，（通用名稱：暗桿），也有升降旋轉(zhuǎn)桿式，（通用名稱：明桿）截止閥是指關(guān)閉件（閥瓣）沿閥座中心線移動的閥門。 1、焊接截止閥使用維護(hù)的目的，在于延長高真空擋板閥壽命和保證啟閉可靠。 2、閥桿螺紋，經(jīng)常與閥桿螺母摩擦，要涂一點(diǎn)黃干油、二硫化鉬或石墨粉，成都自密封截止閥廠家，起潤滑作用。 3、如果長期閑置高真空擋板閥，也要定期轉(zhuǎn)動手輪，對閥桿螺紋添加潤滑劑，以防咬住，成都自密封截止閥廠家。 4、焊接截止閥要經(jīng)常檢查并保持高真空擋板閥另部件完整性。如手輪的固定螺母脫落，成都自密封截止閥廠家，要配齊、不能湊合使用，否則會磨園閥桿上部的四方，逐漸失去配合可靠性，乃至不能開動。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">電站焊接截止閥是由于開閉過程中密封面之間摩擦力小，比較耐用，開啟高度不大，制造容易，維修方便，不僅適用于中低壓，而且適用于高壓。它的閉合原理是，依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質(zhì)流通。焊接截止閥適用于工作溫度≤425℃和≤550℃，工作介質(zhì)為水、空氣、蒸汽的管路上，作為起閉裝置。尤其適用于火電廠汽機(jī)冷凝和真空負(fù)壓系統(tǒng)，起到真空密封隔離作用。焊接截止閥適用于公稱壓力PN1.6～10.0MPa,工作溫度0～450℃的火力電站回水冷凝系統(tǒng)及石油、化工要求與大氣隔離的系統(tǒng)管道上，切斷或接通管路中的介質(zhì)。</p><div

電站截止閥主要特點(diǎn)及用途: </p> <p> 1、閥門與管路連接采用焊接式結(jié)構(gòu)。 </p> <p> 2、密封面不易磨損、擦傷、密封性能好、壽命長。 </p> <p> 3、結(jié)構(gòu)緊湊、啟閉性好、高度小、維修方便。 </p> <p> 4、適用于水、蒸汽、油品管路上，具有耐高溫、耐高壓的特點(diǎn)。 </p> <p> 電站閥結(jié)構(gòu)優(yōu)勢 </p> <p> 1.采用壓力自緊式密封，閥體支管兩端為焊接連接。 </p> <p> 2.閥坐、閥瓣密封面采用鈷基硬質(zhì)合金等離子噴焊而成，耐磨、抗擦傷性能好。 </p> <p> 3.閥桿經(jīng)抗腐蝕性氮化處理，有良好的抗腐蝕性和抗擦傷性。 </p> <p> <br /> </p></p><br /><p>文章來源地址:
