彈簧微啟封閉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,一旦當壓力容器的壓力異常后產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。
彈簧微啟封閉式安全閥區(qū)別于一般的全啟式安全閥，其泄壓后可自動關閉,無需人手動復位,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、水等介質的設備或管路上。A41Y-P/R不銹鋼安全閥適用于工作溫度≤200℃有腐蝕性介質的設備或管路上,作為超壓保護裝置。連接法蘭標準按JB/T……94/系列1。
Scope of application（SANJING VALVE）
A41H type are used for the equipment and pipeline of the petroleum gas air water etc medium what are working temperature are less than ≤300℃ A41Y-P/R type are used for the equipment and pipeline of the quality with corrode medium what the wirking temperatrue are less than 200℃ Take for extra pressure devices Flange connecting dimentsions of comply with Standard series first of JB/T...94
