氣動法(fa)蘭連接(jiē)金屬密(mì)封蝶閥(fá)是引進(jìn)德國MAK公(gōng)司技術(shu)開發的(de)新一代(dai)蝶閥産(chan)品。産品(pin)性能已(yi)優于國(guó)内外領(lǐng)🔞先水平(píng),廣泛适(shì)用于😍冶(yě)金、石油(yóu)、化工、電(dian)力、市政(zhèng)建設等(děng)工業管(guan)道上作(zuò)截斷或(huò)調節介(jiè)質流量(liang)之用。
D643H氣(qì)動法蘭(lan)連接金(jin)屬密封(feng)蝶閥主(zhǔ)要有如(rú)下特點(diǎn):
1. 結構尺(chi)寸短、體(ti)積小、重(zhòng)量輕、操(cāo)作輕便(bian)。
2. 采用整(zhěng)軸結構(gòu),蝶闆為(wéi)桁架式(shi)結構,蝶(die)闆強度(du)高、過流(liú)🏃♀️面積大(dà)、流🌐阻小(xiao)、節省能(néng)源。
3. 獨特(te)的角偏(pian)心設計(ji):本蝶閥(fá)在傳統(tong)的雙偏(pian)心結構(gou)基礎上(shang)配🈚置獨(du)特的角(jiǎo)偏心設(shè)計,充分(fèn)利用凸(tū)輪效💚應(ying),從而實(shí)現閥門(men)開啟時(shi),閥座與(yǔ)密封圈(quān)瞬時脫(tuō)離🔆,在90度(dù)行程上(shang)完全消(xiao)除摩擦(ca)磨損。
4.彈(dan)性金屬(shu)對金屬(shǔ)密封:蝶(die)閥閥座(zuo)表面堆(duī)焊耐溫(wēn)、耐蝕♋合(hé)金㊙️材料(liao),密封圈(quan)由T形密(mi)封環兩(liang)側多層(céng)不鏽鋼(gang)✍️片組成(chéng)。在外加(jiā)轉矩的(de)作用下(xià).彈性密(mi)封圈與(yu)金屬閥(fa)座之間(jiān)的接觸(chù)角産💔生(shēng)輕微的(de)契塊效(xiao)應,使得(de)密封圈(quān)發生柔(rou)動和徑(jìng)向壓縮(suo),使🧡得閥(fá)座360度周(zhou)圈均勻(yun)密封比(bi)壓,從而(er)實現用(yong)最🏃🏻♂️小的(de)轉矩實(shí)現最嚴(yán)密的🐕關(guān)閉。
