碳化硅燒嘴中管螺紋接頭的主要制作材料為不銹鋼，螺紋連接方式可分為內(nèi)螺紋連接和外螺紋連接。這種接頭多用于連接建筑、水利工程、橋梁建筑的管道。壓力表的接頭和接觸液體的零件都是由黃銅制成，主要用于測(cè)量對(duì)銅和銅合金無(wú)腐蝕性、無(wú)性，且不易結(jié)晶和沉淀的氣體或液體壓力。碳化硅燒嘴的這種儀表要求垂直安裝，負(fù)荷穩(wěn)定。電磁閥也是一種碳化硅燒嘴配件，具有內(nèi)螺紋連接口。電磁閥的閥體通常是由不銹鋼和黃銅制造的，它的活塞結(jié)構(gòu)特別，耐磨度高，并且在工作時(shí)不會(huì)產(chǎn)生任何的噪音。加熱爐常用的有焰燒嘴有套管式燒嘴、低壓渦流式燒嘴、扁縫渦流式燒嘴、環(huán)縫渦流式燒嘴、平焰燒嘴等。</p><div
