彈簧微啟封閉式**閥指依靠彈簧的彈性壓力而將閥的瓣膜或柱塞等密封件閉鎖，一旦當(dāng)壓力容器的壓力異常后產(chǎn)生的高壓將克服**閥的彈簧壓力，所以閉鎖裝置被頂開，形成了一個(gè)泄壓通道，將高壓泄放掉。
彈簧微啟封閉式**閥區(qū)別于一般的全啟式**閥，其泄壓后可自動(dòng)關(guān)閉，無需人手動(dòng)復(fù)位，A41H彈簧微啟封閉式**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不銹鋼**閥適用于工作溫度≤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。
