氨用截止閥：J41B氨用截止閥經(jīng)常要用到氧氣、氮氣、氫氣、氬氣等氣體。這些氣體一般都是貯存在的高壓氣體中。使用時通過氨用截止閥使氣體壓力降至實驗所需范圍，再經(jīng)過其它控制閥門細(xì)調(diào)，使氣體輸入使用系統(tǒng)。*J41B氨用截止閥,產(chǎn)品齊全,現(xiàn)貨供應(yīng),!圣核閥門制造(上海)有限公司:4000-678178. 氨用截止閥主要零件材料：零件名稱閥體、閥蓋密封圈填料填料壓蓋閥桿墊片J41B-25C鑄鋼巴氏合金聚四氟乙 烯碳鋼聚四氟乙 烯J41B-25Z灰鑄鐵J41B-25P不銹鋼不銹鋼J41F-25Z灰鑄鐵 碳鋼氨用截止閥性能規(guī)范：公稱壓力PN（MPA）試驗壓力PS（Mpa）適用介質(zhì)適用溫度（℃）2.53.8氨氣、氨液等NH3巴氏合金-40℃+150℃四氟-40℃+200℃4.06.4氨用截止閥主要尺寸及重量：公稱通徑DN（mm）尺 寸（mm）LDD1D2D4bff1Z-φd關(guān)開D3101309060403516244-φ14165185110151309565454016244-φ141651851102015010575555118244-φ141702001202516011585655818244-φ1419721012032180135100786620244-φ1819921314040200145110857620344-φ18248264160502301601251008822344-φ182652951806529018014512011024348-φ183103492208031019516013512126348-φ183403572401003502301901601503034.58-φ233804132801254002702201881763234.58-φ254304513201504803002502182043234.58-φ255054923602006003603102782603434.512-φ25550806400250650425370335313634.512-φ307308804503007504854303903644034.516-φ30-995550本資料出自圣核閥門制造(上海)有限公司http://www.4000678178.com 如需轉(zhuǎn)載請注明。本文關(guān)鍵詞：J41B氨用截止閥本文URL：http://4000678178.com/jiezhifa/155.html
