產(chǎn)品名稱:A48Y帶扳手彈簧微啟式安全閥 |
|
|
|
產(chǎn)品類別:安全閥 |
|
|
|
|
概述 】 適用于工作溫度≤350℃的蒸汽、空氣等介質(zhì)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。
【結(jié)構(gòu)特點】
1、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。閥瓣密封面采用先進的激光淬火技術,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。
【安裝說明】
1、安全閥必須垂直安裝,并最好直接安裝在容器或管道的接頭上。接頭內(nèi)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?shù)呐蛎浌?jié),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(nèi)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(jié)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(chǎn)生背壓影響閥門的排放能力。
