详细介绍: Q41B氨用球阀
Q41B氨气专用球阀专为液氨、氨气、燃气的管路或装置设计。填料采用聚四氟乙烯,密封可靠、绝对物外漏。密封副材料采用聚四氟乙烯或尼龙对阀体本体材料,为软密封,密封可靠。液氨专用球阀适用于液氨气管路系统,作为启闭装置。
主要用途:
氨用球阀在阀体材料上选用耐腐蚀钢(碳素钢添加耐蚀合金元素),可耐燃气、液氨腐蚀,低温可至-40℃-+120℃。阀体全部采用精铸,防止阀门耐腐蚀性能差、壳体易穿孔的缺点。主要适用于冷冻、制冷、化工、石油、食品、冶炼、液化气等单位使用。
使用范围:
☆通经范围:DN15~DN300
☆压力范围:1.6MPa~4.0MPa
☆温度范围:-40℃~120℃
☆介质范围:丙烷、炳烯、甲醇、乙烷、煤气、液氨、液化天然气等低温介质
