安全閥:A41H彈簧微啟封閉式安全閥 |
|
A41H彈簧微啟封閉式安全閥詳細信息: |
彈簧式安全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)生的高壓將克服安全閥的彈簧壓力,所以閉鎖裝置被頂開,形成了一個泄壓通道,將高壓泄放掉。
區(qū)別于一般的全啟式安全閥,其泄壓后可自動關(guān)閉,無需人手動復(fù)位
A41H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不銹鋼安全閥適用于工作溫度≤200℃有腐蝕性介質(zhì)的設(shè)備或管路上,作為超壓保護裝置。連接法蘭標(biāo)準(zhǔn)按JB/T……94/系列1。
