帶扳手(shou)彈簧微(wei)啟式安(an)全閥說(shuō)明:A47H帶扳(bān)手彈簧(huáng)微啟式(shì)安全閥(fá)适用于(yú)工作溫(wēn)度≤350℃的蒸(zheng)汽、空氣(qi)等介質(zhì)的🏃🏻♂️設備(bèi)或管🔆路(lu)上☀️。作為(wéi)超壓保(bǎo)護裝置(zhì)。連接法(fa)蘭标準(zhǔn)按JB/T-94的系(xi)列 帶扳(ban)🙇🏻手彈簧(huang)微啟式(shì)安全閥(fá)結構簡(jian)述
1、彈簧(huang)微啟式(shì)安全閥(fá)具有結(jié)構簡單(dan)、密封性(xing)能好、開(kai)啟壓力(lì)準确🌐、排(pái)放能力(li)大、回座(zuo)壓差小(xiao)、調整方(fāng)便等特(tè)點。
2、噴嘴(zui)型閥座(zuò):閥座為(wéi)位伐爾(ěr)噴嘴型(xíng)閥座,蒸(zhēng)汽流經(jīng)閥座出(chū)口處時(shi)達到音(yin)速,排放(fang)系數大(dà),閥座密(mì)封面堆(dui)焊钴鉻(ge)鎢硬質(zhi)合金,耐(nài)磨抗沖(chòng)蝕,壽命(ming)長。
3、熱彈(dan)性閥瓣(ban):閥瓣設(shè)計為熱(re)彈性結(jié)構,利用(yong)其在介(jiè)質壓力(lì)🛀🏻下微✊小(xiao)的變形(xing),提高密(mì)封能力(lì),克服安(an)全閥✔️在(zai)介質壓(yā)力下臨(lin)近整定(ding)壓力時(shi)的前洩(xiè)現象。閥(fá)瓣🐕密封(feng)面💯采用(yòng)先進的(de)激光淬(cuì)火技術(shu),提高了(le)硬度、耐(nai)磨性、抗(kàng)沖抗性(xing)。
4、調節螺(luo)母:通過(guò)調整調(diao)節螺母(mu),調整彈(dàn)簧壓縮(suō)量,使✌️閥(fa)門♋能夠(gou)很🌍方便(biàn)、很迅速(su)地獲得(de)準确的(de)整定壓(yā)力。
5、背壓(ya)調整套(tào):調整閥(fa)瓣背壓(yā)的輔助(zhù)機構,通(tong)過背壓(ya)調整套(tao)調整🔅,可(kě)獲得合(he)适的回(hui)座壓差(chà)。上調時(shí),使閥門(mén)背壓降(jiàng)✂️低。下調(diào)時,使閥(fa)門背壓(yā)提高。 帶(dài)扳手彈(dàn)簧❄️微啟(qǐ)式安全(quan)閥安裝(zhuāng)說明
1、安(an)全閥必(bì)須垂直(zhí)安裝,并(bing)最好直(zhi)接安裝(zhuāng)在容器(qi)或☎️管道(dao)的接頭(tou)上。接頭(tóu)内徑應(yīng)不小于(yú)安全閥(fá)的進口(kǒu)通徑。
2、安(ān)全閥的(de)出口必(bi)須裝設(she)适當的(de)膨脹節(jie),以防止(zhǐ)排放管(guan)的熱膨(peng)脹給安(ān)全閥帶(dai)來不應(yīng)有的熱(re)應力。排(pái)放管内(nèi)徑應比(bi)🈲閥門出(chū)口直徑(jing)大,長度(du)盡可能(neng)短,避免(miǎn)拐彎🏃🏻♂️。排(pái)放管及(jí)膨脹節(jiē)重量不(bu)應作用(yòng)在安全(quán)閥💯上,應(ying)固定在(zai)建築上(shang)❓。排放管(guan)的中心(xin)線與閥(fá)體的中(zhong)🤩心線間(jian)距離盡(jìn)可能的(de)短。對每(mei)台安全(quan)📧閥都應(yīng)單獨裝(zhuāng)設排放(fang)管。
3、消聲(shēng)器的出(chu)口處要(yao)有足夠(gòu)的面積(jī),防止産(chan)生背壓(yā)影響閥(fá)💰門的排(pái)放能力(li)。
