A48Y彈簧全啟式安全閥
A48Y-16C帶扳手彈簧全啟式安全閥 帶扳手彈簧全啟式安全閥A48Y-16C的詳細介紹帶扳手彈簧全啟式安全閥A48Y-16C適用于工作溫度≤350℃的蒸汽、空氣等介質(zhì)的設(shè)備和管路上。A44Y型彈簧全啟式安全閥適用于工作溫度≤300℃的空氣、石油 等介質(zhì)的設(shè)備和管路上,作為超壓保護裝置。產(chǎn)品連接法蘭標準PN<6.4MPa按JB/和T-94系列1.2標準。PN≥6.4MPa按JB/和T-94系列2標準安全閥的選用由操作壓力決定安全閥的公稱壓力,由操作溫度決定安全閥的使用溫度范圍,由計算出的安全閥的定壓值決定彈簧或杠桿的定壓范圍,再根據(jù)使用介質(zhì)決定安全閥的材質(zhì)和結(jié)構(gòu)型式,再根據(jù)安全閥泄放量計算出安全閥的喉徑。
結(jié)構(gòu)簡述
1、彈簧全啟式安全閥具有結(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。
A48Y帶扳手彈簧全啟式安全閥適用于工作溫度≤350℃的蒸汽、空氣等介質(zhì)的設(shè)備和管路上。
