A47H-帶扳手彈簧微啟式(shì)安全閥
帶(dài)扳手彈(dàn)簧微啟(qǐ)式安全閥說明(míng):A47H帶扳手彈簧微啟式安全閥适(shì)用于工作溫度≤350℃的蒸汽、空氣等(děng)介質的設備或管路上。作為超(chāo)壓保護裝(zhuāng)置。連接法蘭标準按JB/T-94的系(xì)列 帶扳手彈簧微啟式安全閥結構簡述
1、彈簧(huáng)微啟式安全閥具有結構簡單(dān)、密封性能好、開啟壓力準确、排放能力大、回座壓差小、調整方(fāng)便等特點。
2、噴嘴型閥座:閥座為位伐爾噴(pēn)嘴型閥座(zuò),蒸汽流經閥座出口處時達到音速(sù),排放系數大,閥(fá)座(zuò)密封面堆焊钴鉻(gè)鎢硬質合(hé)金,耐磨抗(kàng)沖蝕,壽命長。
3、熱彈性閥瓣:閥瓣設計為熱彈性結構,利用其(qí)在介質壓力下微小的變形,提高密封能力,克服(fú)安全閥在介質壓力下臨近整定(dìng)壓力時的前洩現(xiàn)象。閥瓣密封面采用先進的激光淬火技術,提(tí)高了硬度、耐磨性、抗沖抗性。
4、調節螺(luó)母:通過(guò)調整調節螺母,調整彈簧壓縮量,使閥門能夠很方便、很迅速地獲得準确的整(zhěng)定壓力。
5、背壓調整套:調整閥瓣(bàn)背壓的輔(fǔ)助機構,通過背壓調整套調整,可獲得合(hé)适的回座壓差。上調時,使閥門背壓降低。下調時,使閥門背壓提(tí)高。 帶扳手彈簧微啟式安全閥安裝說明
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。接頭内(nèi)徑應(yīng)不小于安全閥的進(jìn)口通徑。
2、安全閥的出口必須(xū)裝設适當的膨脹節,以防止排放管的熱膨脹給安全(quán)閥帶來(lái)不應有的熱應力。排放(fàng)管内徑應比閥門出口(kǒu)直徑大(dà),長度盡可能短,避免拐彎。排放管及膨(péng)脹節重量不應作用在(zài)安全閥上,應固定在(zài)建築上。排放管的中心線與閥體的(de)中心線間距離盡可能的短。對每台(tái)安全閥都應單獨(dú)裝設排放管(guǎn)。
3、消聲(shēng)器的出口處要有足夠的(de)面積,防止産生背壓影響閥門(mén)的排放能力。
