mso-hansi-font-family:"Times New Roman"">详细说明:
mso-hansi-font-family:"Times New Roman"">型号：DA21F-25T/P
mso-hansi-font-family:"Times New Roman"">一概述：
mso-hansi-font-family:"Times New Roman"">低温安全阀在设备和管路上作为超压保护装置，制造过程将零件浸入低温-196 mso-hansi-font-family:"Times New Roman"">℃的液氮中保冷2 "Times New Roman"">至6小时后取出自然处理，重复循环2 mso-hansi-font-family:"Times New Roman"">次，减少温差和金相组织改变而产生变形，提高阀门在低温时的密封性。用于易燃介质的阀门需防静电设计。
mso-hansi-font-family:"Times New Roman"">靠、起跳压力稳定等特点。
mso-hansi-font-family:"Times New Roman"">二. "Times New Roman"">规范：
mso-hansi-font-family:"Times New Roman"">公称通径：DN25mm
mso-hansi-font-family:"Times New Roman"">公称压力：PN2.5MPa
mso-hansi-font-family:"Times New Roman"">适用介质：LO2 "Times New Roman"">、LN2、LAR mso-hansi-font-family:"Times New Roman"">、LNG "Times New Roman"">等
mso-hansi-font-family:"Times New Roman"">适用温度：-196℃-+80℃
mso-hansi-font-family:"Times New Roman"">三. "Times New Roman"">材质：
mso-hansi-font-family:"Times New Roman"">阀体、阀座：铜/ "Times New Roman"">不锈钢
mso-hansi-font-family:"Times New Roman"">阀顶、阀杆、弹簧：不锈钢
