A47HW帶扳手彈簧微啟式安全閥適用于工作溫度≤350℃的蒸汽、空氣等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的系列
二、結構簡述:
1、彈簧微啟式安全閥具有結構簡單、密封性能好、開啟壓力準確、排放能力大、回座壓差小、調整方便等特點。
2、噴嘴型閥座:閥座為位伐爾噴嘴型閥座,蒸汽流經閥座出口處時達到音速,排放系數大,閥座密封面堆焊鈷鉻鎢硬質合金,耐磨抗沖蝕,壽命長。
3、熱彈性閥瓣:閥瓣設計為熱彈性結構,利用其在介質壓力下微小的變形,提高密封能力,克服安全閥在介質壓力下臨近整定壓力時的前泄現象。閥瓣密封面采用*的激光淬火技術,提高了硬度、耐磨性、抗沖抗性。
4、調節螺母:通過調整調節螺母,調整彈簧壓縮量,使閥門能夠很方便、很迅速地獲得準確的整定壓力。
5、背壓調整套:調整閥瓣背壓的輔助機構,通過背壓調整套調整,可獲得合適的回座壓差。上調時,使閥門背壓降低。下調時,使閥門背壓提高。
三、安裝說明:
1、安全閥必須垂直安裝,并直接安裝在容器或管道的接頭上。接頭內徑應不小于安全閥的進口通徑。
2、安全閥的出口必須裝設適當的膨脹節,以防止排放管的熱膨脹給安全閥帶來不應有的熱應力。排放管內徑應比閥門出口直徑大,長度盡可能短,避免拐彎。排放管及膨脹節重量不應作用在安全閥上,應固定在建筑上。排放管的中心線與閥體的中心線間距離盡可能的短。對每臺安全閥都應單獨裝設排放管。
3、消聲器的出口處要有足夠的面積,防止產生背壓影響閥門的排放能力。
