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,一旦當壓力容器的壓力異常后產生的高壓將克服**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，其泄壓后可自動關閉,無需人手動復位,A41H彈簧微啟封閉式**閥適用于工作溫度≤300℃的石油氣、空氣、水等介質的設備或管路上。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

**閥訂貨主要事項：
**閥介質, 壓力等級,開啟方式（全啟/微啟）設定起跳壓力,確定閥門尺寸,連接方式,標準大耐溫,釋放流量/每小時,閥體材質,內部閥體結構,工作原理,安裝說明等相關技術資料.**閥選型主要依據(jù)就是（起跳壓力及整齊壓力流量溫度）口徑一般設計院會給出,而實際上通過蒸汽壓力,流量及起跳壓力,可以推測出**閥的尺寸.一般會比設計院所選出的口徑小一號，當使用的場合非常重要或環(huán)境比較復雜時,請您盡量提供設計圖紙和詳細參數(shù)，由我們的三精閥門公司專家為您審核把關。感謝您訪問我們的網(wǎng)站【www.cnsjfm.cn】
