防爆鎧裝電纜隔爆密封接頭規(guī)格介紹

鎧裝電纜隔爆密封接頭
一、 結(jié)構(gòu)和性能(Structure and function)
該系列鎧裝電纜隔爆密封接頭結(jié)構(gòu)形式分Ⅰ、Ⅱ型兩種。Ⅰ型為一端外螺紋、另一端夾緊裝置，Ⅱ型為一端外螺紋，另一端內(nèi)螺紋。接頭體內(nèi)還通過夾緊置防止電纜拔脫，內(nèi)裝兩道彈性密封墊使電纜引出同時(shí)阻隔爆炸氣體的進(jìn)、出。主要用于橡膠電纜和塑料電纜進(jìn)、出防爆技術(shù)要求高的引入裝置中。其防爆標(biāo)志為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,  

防爆密封接頭的材質(zhì)是銅合金，黃銅鍍鎳，不銹鋼由于銅與優(yōu)質(zhì)不銹鋼的良好導(dǎo)熱性能及幾乎不含碳的特質(zhì)，使接頭與物體摩擦或撞擊時(shí)，短時(shí)間內(nèi)產(chǎn)生的熱量被吸收及傳導(dǎo)，另一原因由于銅與不銹鋼本身相對(duì)較軟，摩擦和撞擊時(shí)有很好的退讓性，不易產(chǎn)生微小金屬顆粒，于是我們幾乎看不到火花，因此來達(dá)到防爆的效果。

　主要適用范圍是：石油精煉和石油化學(xué)工業(yè)、煤礦、油田、天然氣化學(xué)工業(yè)、化纖工業(yè)、油漆工業(yè)、肥料工業(yè)、各種藥品工業(yè)。石油輪和液化石油氣的車輛、經(jīng)營(yíng)易燃易爆品的倉庫、電解車間、通訊機(jī)裝配車間、要求接頭不生銹、耐磨抗磁的場(chǎng)所等。
