防爆铠装电缆隔爆密封接头规格介绍

铠装电缆隔爆密封接头
一、 结构和性能(Structure and function)
该系列铠装电缆隔爆密封接头结构形式分Ⅰ、Ⅱ型两种。Ⅰ型为一端外螺纹、另一端夹紧装置，Ⅱ型为一端外螺纹，另一端内螺纹。接头体内还通过夹紧置防止电缆拔脱，内装两道弹性密封垫使电缆引出同时阻隔爆炸气体的进、出。主要用于橡胶电缆和塑料电缆进、出防爆技术要求高的引入装置中。其防爆标志为ExdⅡC

There exist two structures(Ⅰ、Ⅱ)among the series of isolated explosion & seal joint with armoured cable. I tape: one end is external screw, the other clamp. Ⅱ tape one end is external screw. The other internal screw. The joint body has clamp which can prevents cables from being pulled out. Two elastic & sealing filler strips are fixed inside that can make cables spread out and separate exploding gases from going in & out .. the structures are mainly applied in the rubber & plastecs cable devices where explosion-proof technology ids of high requirements which are marked with ExdⅡC,  

防爆密封接头的材质是铜合金，黄铜镀镍，不锈钢由于铜与优质不锈钢的良好导热性能及几乎不含碳的特质，使接头与物体摩擦或撞击时，短时间内产生的热量被吸收及传导，另一原因由于铜与不锈钢本身相对较软，摩擦和撞击时有很好的退让性，不易产生微小金属颗粒，于是我们几乎看不到火花，因此来达到防爆的效果。

　主要适用范围是：石油精炼和石油化学工业、煤矿、油田、天然气化学工业、化纤工业、油漆工业、肥料工业、各种药品工业。石油轮和液化石油气的车辆、经营易燃易爆品的仓库、电解车间、通讯机装配车间、要求接头不生锈、耐磨抗磁的场所等。
