安全閥的選用原則:
1、蒸汽鍋爐安全閥,一般選用敞開(kāi)全啟式彈簧安全閥0490系列;
2、液體介質(zhì)用安全閥,一般選用微啟式彈簧安全閥0485系列;
3、空氣或其他氣體介質(zhì)用安全閥,一般選用封閉全啟式彈簧安全閥;
4、液化石油氣汽車槽車或液化石油氣鐵路罐車用安全閥,一般選用全啟式內(nèi)裝安全閥;
5、采油井出口用安全閥,一般選用先導(dǎo)式安全閥;
6、蒸汽發(fā)電設(shè)備的高壓旁路安全閥,一般選用具有安全和控制雙重功能的先導(dǎo)式安全閥
7、若要求對(duì)安全閥做定期開(kāi)啟試驗(yàn)時(shí),應(yīng)選用帶提升扳手的安全閥。當(dāng)介質(zhì)壓力達(dá)到開(kāi)啟壓力的75%以上時(shí),可利用提升扳手將閥瓣從閥座上略為提起,以檢查安全閥開(kāi)啟的靈活性;
8、若介質(zhì)溫度較高時(shí),為了降低彈簧腔室的溫度,一般當(dāng)封閉式安全閥使用溫度超過(guò)300℃及敞開(kāi)式安全閥使用溫度超過(guò)350℃時(shí),應(yīng)選用帶散熱器的安全閥;
9、若安全閥出口背壓是變動(dòng)的,其變化量超過(guò)開(kāi)啟壓力的10%時(shí),應(yīng)選用波紋管安全閥;
10、若介質(zhì)具有腐蝕性時(shí),應(yīng)選用波紋管安全閥,防止重要零件因受介質(zhì)腐蝕而失效。
11、安全閥的安裝和維護(hù)應(yīng)注意以下事項(xiàng)施工、安裝要點(diǎn)
1)、安裝位置、高度、進(jìn)出口方向必須符合設(shè)計(jì)要求,注意介質(zhì)流動(dòng)的方向應(yīng)與閥體所標(biāo)箭頭方向*,連接應(yīng)牢固緊密。
2)、閥門安裝前必須進(jìn)行外觀檢查,閥門的銘牌應(yīng)符合現(xiàn)行國(guó)家標(biāo)準(zhǔn)《通用閥門標(biāo)志》GB 12220的規(guī)定。對(duì)于工作壓力大于1.0 MPa及在主干管上起到切斷作用的閥門,安裝前應(yīng)進(jìn)行強(qiáng)度和嚴(yán)密性能試驗(yàn),合格后方準(zhǔn)使用。強(qiáng)度試驗(yàn)時(shí),試驗(yàn)壓力為公稱壓力的1.5倍,持續(xù)時(shí)間不少于5min,閥門殼體、填料應(yīng)無(wú)滲漏為合格。嚴(yán)密性試驗(yàn)時(shí),試驗(yàn)壓力為公稱壓力的1.1倍;試驗(yàn)持續(xù)的時(shí)間符合GB 50243的要求.1.各種安全閥都應(yīng)垂直安裝。
12、安全閥出口處應(yīng)無(wú)阻力,避免產(chǎn)生受壓現(xiàn)象。
13、安全閥在安裝前應(yīng)專門測(cè)試,并檢查其官密封性。
14、對(duì)使用中的安全閥應(yīng)作定期檢查。
