A41H彈簧微啟封閉式安全閥
安全閥是一種由進(jìn)口靜壓開啟的自動(dòng)泄壓防護(hù)裝置,它是壓力容器最為重要的安全附件之一,它的功能是:當(dāng)容器內(nèi)壓力超過某一定值時(shí),依靠介質(zhì)自身的壓力自動(dòng)開啟閥門,迅速排出一定數(shù)量的介質(zhì)。當(dāng)容器內(nèi)的壓力降到允許值時(shí),閥又自動(dòng)關(guān)閉,使容器內(nèi)壓力始終低于允許壓力的上限,自動(dòng)防止因超壓而可能出現(xiàn)的事故,所以安全閥又被稱為壓力容器的最終保護(hù)裝置。
安全閥常見故障及原因
【安全閥漏氣】(1)閥芯與閥座接觸面不嚴(yán)密;(2)閥芯與閥座接觸面有臟物;(3)閥桿偏斜。
【安全閥到規(guī)定壓力時(shí)不開啟】(1)閥芯與閥座粘住,可做手動(dòng)排氣試驗(yàn)排除;(2)彈簧式安全閥的彈簧調(diào)整壓力過大,應(yīng)重新調(diào)整;(3)杠桿式安全閥的重錘向后移動(dòng),應(yīng)將重錘移到原來定壓的位置上,用限動(dòng)螺絲緊固。
【安全閥不規(guī)定壓力時(shí)開啟】(1)彈簧式安全閥的彈簧調(diào)整壓力不夠、彈簧失效或彈力不足,應(yīng)重調(diào)或重?fù)Q安全閥;(2)杠桿式安全閥重錘向前移動(dòng),應(yīng)將重錘移到原來定壓的位置上,用限動(dòng)螺絲緊固。
A41H彈簧微啟封閉式安全閥:
A41H彈簧微啟封閉式安全閥適用于工作溫度≤300℃的石油氣、空氣、水等介質(zhì)的設(shè)備或管路上。A41Y-P/R型適用于工作溫度≤200℃有腐蝕性介質(zhì)的設(shè)備或管路上,作為超壓保護(hù)裝置。連接法蘭標(biāo)準(zhǔn)按JB/T……94/系列1。
