Conflat 法兰 (CF) 硼硅酸盐玻璃适配器 3/4 英寸至 CF 2-3/4 英寸、Schott 8250、Kovar 至不锈钢真空配件
用于将硼硅酸盐玻璃组件连接到金属


这些硼硅酸盐玻璃至 Kovar Conflat 适配器真空配件的法兰尺寸为 ConFlat (CF) 2-3/4 英寸至 3/4 英寸硼硅酸盐玻璃。 这些 ConFlat (CF) 2-3/4 英寸至 3/4 英寸管硼硅酸盐玻璃适配器用于密封 Kovar 金属或钼,并常用于以下应用:高度电绝缘、发射管、图像放大器管、氦氖激光器、光纤包层管、臭氧发生器、进入玻璃外壳的电镀导体和其他电子零件,例如真空管、阀门、X 射线管和微波管以及一些灯泡。Kovar 是一种镍钴铁合金,成分与 Fernico 1 相同,设计为具有与硼硅酸盐玻璃基本相同的热膨胀特性(30 至 200°C 之间为 ~5 × 10−6 /K,800°C 时为 ~10 × 10−6 /K),以允许两种材料在一定温度范围内紧密的机械连接。

Kovar 的发明是为了满足对可靠的玻璃-金属密封的需求,这种密封是电子设备(如灯泡、真空管、阴极射线管)以及化学和其他科学研究中的真空系统所必需的。大多数金属无法密封到玻璃上,因为它们的热膨胀系数与玻璃不同,因此当接头在制造后冷却时,由于玻璃和金属的差异膨胀率而产生的应力会导致接头破裂。

ConFlat (CF) 法兰用于超高真空应用。这些配件使用铜垫圈和刀口法兰来实现高真空密封,可在低至 10-13 托 (10-11 Pa) 的条件下运行,并可加热到 450 °C 进行烘烤。北美法兰尺寸以英寸为单位,按法兰外径表示:1-1/3(“mini conflat”)、2¾、4½、6、8、10、12、13¼、14 和 16½。在欧洲和亚洲,尺寸以毫米为单位,按管内径表示:DN16、DN40、DN63、DN100、DN160、DN200、DN250。这些真空配件由硼硅酸盐 Schott 8250 玻璃制成,密封在 Kovar 金属上,并焊接到耐腐蚀不锈钢真空配件上。


3/4 英寸硼硅酸盐玻璃适配器至 Conflat CF 2-3/4 英寸
CF 法兰尺寸:CF 2-3/4 英寸不锈钢
硼硅酸盐玻璃尺寸:3/4 英寸外径
过渡金属:Kovar
常见尺寸:A= 玻璃直径 3/4 英寸 B= 长度 3.94 英寸
