A41H/Y-16C彈簧封閉式安全閥 不銹鋼安全閥
概述
A41H/Y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。公稱壓力:1.6MPa-10.0MPa,A41Y-P/R型適用于工作溫度≤200℃有腐蝕性介質(zhì)的設(shè)備或管路上,作為超壓保護裝置。當設(shè)備和管路內(nèi)壓力超過允許值時,閥門自動開啟,繼而全量排放;當壓力降低到規(guī)定值時,閥門自動關(guān)閉,保證設(shè)備和管路安全運行。連接法蘭標準按JB/T……94/系列。
A41H/Y-16C彈簧封閉式安全閥 不銹鋼安全閥結(jié)構(gòu)簡述
1、A41H/Y彈簧微啟式安全閥具有結(jié)構(gòu)簡單、密封性能好、開啟壓力準確、排放能力大、回座壓差小、調(diào)整方便等特點。
2、噴嘴型閥座:閥座為位伐爾噴嘴型閥座,蒸汽流經(jīng)閥座出口處時達到音速,排放系數(shù)大,閥座密封面堆焊鈷鉻鎢硬質(zhì)合金,耐磨抗沖蝕,壽命長。
3、熱彈性閥瓣:閥瓣設(shè)計為熱彈性結(jié)構(gòu),利用其在介質(zhì)壓力下微小的變形,提高密封能力,克服安全閥在介質(zhì)壓力下臨近整定壓力時的前泄現(xiàn)象。閥瓣密封面采用*的激光淬火技術(shù),提高了硬度、耐磨性、抗沖抗性。
4、調(diào)節(jié)螺母:通過調(diào)整調(diào)節(jié)螺母,調(diào)整彈簧壓縮量,使閥門能夠很方便、很迅速地獲得準確的整定壓力。
5、背壓調(diào)整套:調(diào)整閥瓣背壓的輔助機構(gòu),通過背壓調(diào)整套調(diào)整,可獲得合適的回座壓差。上調(diào)時,使閥門背壓降低。下調(diào)時,使閥門背壓提高。
