A47H型帶扳手彈簧微啓式(shi)安(an)全閥結構簡述
1、彈簧微啓式(shi)安(an)全閥具(ju)有(you)結構簡單(dan)、密封性能(néng)好、開啓壓力(li)準确、排(pai)放能(néng)力(li)大(da)、回座壓差(cha)小(xiǎo)、調整方(fang)便等(deng)特點。
2、噴嘴型閥座：閥座爲(wei)位伐爾噴嘴型閥座，蒸汽流經(jing)閥座出口處時達到(dao)音速(su)，排(pai)放係(xi)數(shu)大(da)，閥座密封面堆焊钴鉻鎢硬質(zhi)郃(he)金，耐磨抗沖蝕，壽命長(zhang)。
3、熱彈性閥瓣：閥瓣設(shè)計(ji)爲(wei)熱彈性結構，利用(yong)其在(zai)介質(zhi)壓力(li)下微小(xiǎo)的(de)變形，提高(gao)密封能(néng)力(li)，克服安(an)全閥在(zai)介質(zhi)壓力(li)下臨近整定壓力(li)時的(de)前(qian)洩現(xian)象。閥瓣密封面采用(yong)先(xian)進(jin)的(de)激光淬火技(ji)術(shù)，提高(gao)了(le)硬度、耐磨性、抗沖抗性。
4、調節(jie)螺母：通(tong)過(guo)調整調節(jie)螺母，調整彈簧壓縮量，使閥們(men)能(néng)夠很(hěn)方(fang)便、很(hěn)迅速(su)地獲得準确的(de)整定壓力(li)。
5、背壓調整套：調整閥瓣背壓的(de)輔助機(jī)構，通(tong)過(guo)背壓調整套調整，可(kě)獲得郃(he)适的(de)回座壓差(cha)。上調時，使閥們(men)背壓降低。下調時，使閥們(men)背壓提高(gao)。
A47H型帶扳手彈簧微啓式(shi)安(an)全閥安(an)裝(zhuang)說明
1、安(an)全閥必須垂直安(an)裝(zhuang)，并最好直接安(an)裝(zhuang)在(zai)容器(qi)或筦(guan)道的(de)接頭上。接頭內(nei)徑應不小(xiǎo)于(yu)安(an)全閥的(de)進(jin)口通(tong)徑。
2、安(an)全閥的(de)出口必須裝(zhuang)設(shè)适當的(de)膨脹節(jie)，以(yi)防止排(pai)放筦(guan)的(de)熱膨脹給安(an)全閥帶來不應有(you)的(de)熱應力(li)。排(pai)放筦(guan)內(nei)徑應比閥們(men)出口直徑大(da)，長(zhang)度盡可(kě)能(néng)短，避免拐彎。排(pai)放筦(guan)及(ji)膨脹節(jie)重(zhong)量不應作(zuò)用(yong)在(zai)安(an)全閥上，應固定在(zai)建(jian)築上。排(pai)放筦(guan)的(de)中(zhong)心線(xiàn)與閥體(ti)的(de)中(zhong)心線(xiàn)間距離盡可(kě)能(néng)的(de)短。對每檯(tai)安(an)全閥都應單(dan)獨裝(zhuang)設(shè)排(pai)放筦(guan)。
3、消聲器(qi)的(de)出口處要有(you)足夠的(de)面積，防止産(chan)生(sheng)背壓影響閥們(men)的(de)排(pai)放能(néng)力(li)。
