帶扳(ban)手彈(dan)簧微(wei)啟式(shi)安全(quan)閥說(shuo)明：A47H帶(dai)扳手(shou)彈簧(huang)微啟(qi)式安(an)全閥(fa)适用(yong)于工(gong)作溫(wen)度≤350℃的(de)蒸汽(qi)、空氣(qi)等介(jie)質的(de)設備(bei)或管(guan)路上(shang)。作為(wei)超壓(ya)保護(hu)裝置(zhi)。連接(jie)法蘭(lan)标準(zhun)按JB/T-94的(de)系列(lie) 帶扳(ban)㊙️手彈(dan)簧微(wei)啟式(shi)安全(quan)閥結(jie)構簡(jian)述
1、彈(dan)簧微(wei)啟式(shi)安全(quan)閥具(ju)有結(jie)構簡(jian)單、密(mi)封性(xing)能好(hao)、開啟(qi)🥑️壓👹力(li)準🥑️确(que)、排放(fang)能力(li)大、回(hui)座壓(ya)差小(xiao)、調整(zheng)方便(bian)等特(te)點。
2、噴(pen)嘴型(xing)閥座(zuo)：閥座(zuo)為位(wei)伐爾(er)噴嘴(zui)型閥(fa)座，蒸(zheng)汽流(liu)經😮💨閥(fa)座💫出(chu)口處(chu)👀時達(da)到音(yin)速，排(pai)放系(xi)數大(da)，閥座(zuo)密封(feng)面👩🏿❤️💋👨🏽堆(dui)焊钴(gu)鉻鎢(wu)硬質(zhi)合金(jin)，耐磨(mo)抗沖(chong)蝕，壽(shou)命長(zhang)。
3、熱彈(dan)性閥(fa)瓣：閥(fa)瓣設(she)計為(wei)熱彈(dan)性結(jie)構，利(li)用其(qi)在介(jie)🚶🏾♀️➡️質壓(ya)力㊙️下(xia)微👼🏾小(xiao)的變(bian)形，提(ti)高密(mi)封能(neng)力，克(ke)服安(an)全閥(fa)在介(jie)質壓(ya)力下(xia)臨近(jin)整定(ding)壓力(li)時的(de)前洩(xie)現象(xiang)。閥瓣(ban)密封(feng)面采(cai)用先(xian)進的(de)激光(guang)淬火(huo)技術(shu)，提高(gao)了硬(ying)度、耐(nai)磨性(xing)、抗沖(chong)抗性(xing)。
4、調節(jie)螺母(mu)：通過(guo)調整(zheng)調節(jie)螺母(mu)，調整(zheng)彈簧(huang)壓縮(suo)量，使(shi)閥門(men)能夠(gou)很🤑方(fang)便、很(hen)迅速(su)地獲(huo)得準(zhun)确的(de)整定(ding)壓力(li)。
5、背壓(ya)調整(zheng)套：調(diao)整閥(fa)瓣背(bei)壓的(de)輔助(zhu)機構(gou)，通過(guo)背壓(ya)調整(zheng)套調(diao)整，可(ke)獲得(de)合适(shi)的回(hui)座壓(ya)差。上(shang)調時(shi)，使閥(fa)門背(bei)壓降(jiang)低。下(xia)🧛🏾♀️調時(shi)，使閥(fa)門背(bei)壓提(ti)高。 帶(dai)扳手(shou)彈簧(huang)微啟(qi)式🙂↕️安(an)全閥(fa)安裝(zhuang)說明(ming)
1、安全(quan)閥必(bi)須垂(chui)直安(an)裝，并(bing)最好(hao)直接(jie)安裝(zhuang)在容(rong)器或(huo)管道(dao)的接(jie)🧑🏾🎄頭ˇ上(shang)。接頭(tou)内徑(jing)應不(bu)小于(yu)安全(quan)閥的(de)進口(kou)…通徑(jing)。
2、安全(quan)閥的(de)出口(kou)必須(xu)裝設(she)适當(dang)的膨(peng)脹節(jie)，以防(fang)止排(pai)放👯🏾♂️管(guan)的熱(re)膨脹(zhang)給安(an)全閥(fa)帶來(lai)不應(ying)有的(de)熱應(ying)力。排(pai)放管(guan)内徑(jing)👯🏾♂️應比(bi)閥門(men)出口(kou)😌直徑(jing)大，長(zhang)度盡(jin)可能(neng)短，避(bi)免拐(guai)彎🔞。排(pai)放管(guan)及膨(peng)脹節(jie)重量(liang)不應(ying)作用(yong)在安(an)全閥(fa)上，應(ying)固定(ding)在建(jian)築上(shang)。排放(fang)管的(de)中心(xin)線與(yu)🙉閥體(ti)的中(zhong)心線(xian)間距(ju)離盡(jin)可能(neng)的短(duan)。對每(mei)台安(an)全閥(fa)都應(ying)單獨(du)裝設(she)排放(fang)管。
3、消(xiao)聲器(qi)的出(chu)口處(chu)要有(you)足夠(gou)的面(mian)積，防(fang)止産(chan)生背(bei)壓🙂↔️影(ying)響閥(fa)門🥑️的(de)排放(fang)能力(li)。
