**閥是一種由進口靜壓開啟的自動泄壓防護裝置,它是壓力容器*為重要的**附件之一,它的功能是:當容器內壓力超過某一定值時,依靠介質自身的壓力自動開啟閥門,迅速排出一定數量的介質。當容器內的壓力降到允許值時,閥又自動關閉,使容器內壓力始終低于允許壓力的上限,自動防止因超壓而可能出現的事故,所以**閥又被稱為壓力容器的*終保護裝置。
**閥常見故障及原因
【**閥漏氣】(1)閥芯與閥座接觸面不嚴密;(2)閥芯與閥座接觸面有臟物;(3)閥桿偏斜。
【**閥到規定壓力時不開啟】(1)閥芯與閥座粘住,可做手動排氣試驗排除;(2)彈簧式**閥的彈簧調整壓力過大,應重新調整;(3)杠桿式**閥的重錘向后移動,應將重錘移到原來定壓的位置上,用限動螺絲緊固。
【**閥不規定壓力時開啟】(1)彈簧式**閥的彈簧調整壓力不夠、彈簧失效或彈力不足,應重調或重換**閥;(2)杠桿式**閥重錘向前移動,應將重錘移到原來定壓的位置上,用限動螺絲緊固。
41h型適用于工作溫度≤300℃的石油氣、空氣、水等介質的設備或管路上。a41y-p/r型適用于工作溫度≤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。
結構簡述
1、彈簧微啟式**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**閥在介質壓力下臨近整定壓力時的前泄現象。閥瓣密封面采用先進的激光淬火技術,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。
安裝說明
1、**閥必須垂直安裝,并*好直接安裝在容器或管道的接頭上。接頭內徑應不小于**閥的進口通徑。
2、**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**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**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**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。
