A41H-彈簧微(wei)啟封閉(bì)式安全(quan)閥

介質的(de)設備或(huò)管路上(shang),作為超(chāo)壓保護(hù)裝置。連(lián)接法蘭(lan)标準按(an)jb/t……94/系列。
彈(dan)簧微啟(qǐ)封閉式(shì)安全閥(fa)結構簡(jiǎn)述
1、彈簧(huáng)微啟式(shi)安全閥(fa)具有結(jié)構簡單(dan)、密封性(xìng)能好、開(kai)啟💚壓力(li)準确、排(pái)放能力(lì)大、回座(zuo)壓差小(xiao)、調整方(fang)便等特(te)點。
2、噴嘴(zuǐ)型閥座(zuò):閥座為(wéi)位伐爾(er)噴嘴型(xing)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(mi)封面堆(duī)焊🙇♀️钴鉻(ge)鎢硬💋質(zhi)合金,耐(nài)磨抗沖(chong)蝕,壽命(ming)長。
3、熱彈(dàn)性閥瓣(ban):閥瓣設(shè)計為熱(re)彈性結(jie)構,利用(yong)其在介(jiè)質♌壓力(li)⁉️下🍉微小(xiao)的變形(xing),提高密(mì)封能力(li),克服安(an)全閥⁉️在(zài)介質壓(yā)力下臨(lín)近整定(dìng)💰壓力時(shí)的前洩(xie)現象。閥(fá)瓣密封(feng)面采用(yong)先進的(de)激🏃光淬(cuì)火技術(shù),提高了(le)硬度、耐(nài)磨性、抗(kàng)沖👅抗性(xìng)。
4、調節螺(luo)母:通過(guo)調整調(diào)節螺母(mu),調整彈(dan)簧壓縮(suo)量,使⛱️閥(fa)門能❗夠(gou)很方便(bian)、很迅速(sù)地獲得(de)準确的(de)整定壓(yā)力。
5、背壓(yā)調整套(tào):調整閥(fa)瓣背壓(yā)的輔助(zhu)機構,通(tōng)過背壓(yā)調整套(tao)調💋整,可(ke)獲得合(he)适的回(hui)座壓差(chà)。上調時(shí),使閥門(men)背✂️壓降(jiang)低。下調(diao)時👈,使閥(fa)門背壓(ya)提高。 彈(dan)簧微啟(qǐ)封閉式(shì)安全閥(fa)安裝說(shuo)明
1、安全(quán)閥必須(xū)垂直安(ān)裝,并最(zuì)好直接(jie)安裝在(zai)容器或(huo)管道的(de)🔞接頭上(shang)。接頭内(nei)徑應不(bu)小于安(an)全閥的(de)進口通(tōng)徑。
2、安全(quan)閥的出(chu)口必須(xu)裝設适(shì)當的膨(péng)脹節,以(yǐ)防止排(pai)放😘管的(de)🈲熱膨🔆脹(zhang)給安全(quan)閥帶來(lái)不應有(yǒu)的熱應(yīng)力。排放(fàng)管内徑(jing)應比閥(fá)門出口(kǒu)直徑大(dà),長度盡(jin)可能短(duǎn),避免拐(guǎi)彎。排放(fang)管及膨(peng)脹節重(zhong)量㊙️不應(yīng)作用在(zài)安全閥(fá)上,應固(gu)定在建(jiàn)築上。排(pái)放管的(de)中心線(xian)與閥體(tǐ)的中心(xin)線間距(jù)離盡可(kě)能的短(duǎn)。對每台(tai)安全閥(fá)都應單(dan)獨裝設(shè)排放管(guǎn)。
3、消聲器(qì)的出口(kou)處要有(yǒu)足夠的(de)面積,防(fang)止産生(sheng)背壓影(yǐng)響閥門(mén)💰的排放(fang)能力。
