彈簧微啟封閉式安全閥產(chǎn)品概述
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(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(kāi),形成了一個(gè)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(dòng)關(guān)閉,無(wú)需人手動(dòng)復(fù)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(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(hù)裝置。連接法蘭標(biāo)準(zhǔn)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
