特點

·底進側出，流路簡單，阻力小，閥體容量大
·雙導向，閥工作穩定性好
·可調范圍大，固有可調比50
·波紋管密封對移動的閥桿形成*的密封，堵絕流體外漏
·采用浮動套連接，安(an)裝(zhuang)方便

氣(qi)動薄膜低(di)(di)溫(wen)調(diao)節閥(fa)是一(yi)種(zhong)在低(di)(di)溫(wen)、深(shen)(shen)冷場合(he)(he)使用(yong)(yong)的調(diao)節閥(fa)。采(cai)用(yong)(yong)長頸閥(fa)蓋保(bao)溫(wen)，配(pei)用(yong)(yong)多彈簧(huang)執(zhi)行機(ji)構(gou)，具有(you)總體(ti)(ti)結構(gou)緊湊、重量(liang)輕、穩(wen)定性(xing)好等優點(dian)。閥(fa)體(ti)(ti)采(cai)用(yong)(yong)精密(mi)(mi)鑄造角形結構(gou)，材料為(wei)鋁合(he)(he)金，具有(you)良好的耐低(di)(di)溫(wen)性(xing)。波紋管(guan)密(mi)(mi)封保(bao)證了調(diao)節閥(fa)在低(di)(di)溫(wen)場合(he)(he)不外漏。因而廣(guang)泛應(ying)用(yong)(yong)于(yu)冶金、空分、制(zhi)氧(yang)、石油(you)、化工(gong)(gong)等低(di)(di)溫(wen)、深(shen)(shen)冷場合(he)(he)。特(te)別適用(yong)(yong)于(yu)精確控制(zhi)低(di)(di)溫(wen)氣(qi)體(ti)(ti)、流體(ti)(ti)（如液氧(yang)、液氬等）的工(gong)(gong)藝參數保(bao)持在給定值。

    氣(qi)動薄膜低溫調節閥本系列產(chan)品(pin)有(you)(you)連接板(ban)安裝(zhuang)型(xing)、浮動套安裝(zhuang)型(xing)兩種(zhong)(zhong)(zhong)，公稱壓(ya)力(li)等(deng)級(ji)為PN0.6MPa，閥體(ti)口徑范圍(wei) DN20～100，適合流體(ti)溫度-60℃～-200℃范圍(wei)內多種(zhong)(zhong)(zhong)檔次(ci)。泄(xie)漏量等(deng)級(ji)有(you)(you)Ⅳ級(ji)和Ⅵ級(ji)二種(zhong)(zhong)(zhong)。流量特性(xing)為線性(xing)或(huo)等(deng)百分比。多種(zhong)(zhong)(zhong)多樣的品(pin)種(zhong)(zhong)(zhong)供(gong)選擇(ze)。
