A41H-彈簧微啟封閉(bì)式安全閥
彈簧微啟封閉式安全閥說(shuō)明:A41H彈簧微啟封閉式安全閥适用于工作(zuò)溫度≤300℃的石油氣、空氣、水等介質(zhì)的設備或管路上。A41y-p/r型(xíng)适(shì)用于工作溫度≤200℃有腐蝕性
介質的設(shè)備或管路上(shàng),作為超壓保護裝置(zhì)。連接法蘭标準按jb/t……94/系列。
彈簧微啟封閉式安全閥結構簡述
1、彈簧微啟式安全閥具有結構簡單、密封性能好(hǎo)、開啟壓力準确(què)、排放能力大(dà)、回(huí)座壓差小、調整(zhěng)方便等特點。
2、噴嘴型閥座:閥座為位伐(fá)爾噴嘴型閥座,蒸汽流經閥座出口處時達到音速,排(pái)放系數大,閥座密封面堆焊钴鉻鎢硬質合金,耐磨抗沖蝕,壽(shòu)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(yā)力下微小的變形,提高(gāo)密封能(néng)力,克服安全閥(fá)在(zài)介質壓力下臨近整定壓力時的前洩現象。閥瓣密封面采用先進的激光淬火技術,提高(gāo)了硬度、耐(nài)磨性、抗沖抗(kàng)性(xìng)。
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(huò)得準确的整定壓力。
5、背壓調整(zhěng)套:調整閥瓣背壓的輔助機構,通(tōng)過背壓調整套調(diào)整,可獲得合适的回(huí)座壓差。上調時,使閥門背壓降低。下調時,使閥門背壓提高。 彈簧微(wēi)啟封閉式(shì)安全閥安(ān)裝說明
1、安全閥必須垂直安裝,并最好直接安(ān)裝在容(róng)器或管道的接頭(tóu)上。接頭内徑應不(bú)小于安全閥的進口通徑。
2、安全(quán)閥的出口必須裝設适(shì)當的膨脹節,以防止排放管的(de)熱膨脹給安全(quán)閥帶來不(bú)應有的熱(rè)應力。排放管内徑應比(bǐ)閥門出口直徑大,長度盡可能短,避免拐彎。排放管及(jí)膨(péng)脹節重量不應作用在安全(quán)閥上(shàng),應固定在建築上。排放管的中心線與閥體的中(zhōng)心(xīn)線(xiàn)間距離盡可能的短。對每台(tái)安全閥都應(yīng)單獨(dú)裝設排(pái)放管。
3、消聲器的出口處要有足夠的(de)面積,防止産生背壓影(yǐng)響閥門的排(pái)放能(néng)力。
