硬質合金加工閥芯流程與技術要求
閥門是在流體體系中，用來操控流體的方向、壓力、流量的設備是使配管和設備內的介質（液體、氣體、粉末）流動或停止并能操控其流量的設備，閥門的應用范圍很廣所以對于閥門的硬質合金加工顯得尤為重要。
用于流體操控體系的閥門，從簡略的截止閥到極為雜亂的自控體系中所用的各種閥門，其品種和規范相當繁多，所以說法也不完全一致，有的按其用處和效果分類（截斷閥類，調節閥類，止回閥類，分流閥類，安全閥類），有的按其閥體的資料分類（非金屬資料閥門，金屬資料閥門，金屬閥體襯里閥門），不過目前世界、國內常用的分類辦法是既按原理、效果又按結構劃分的辦法，一般分閘閥、截止閥、節流閥、外表閥、柱塞閥、隔膜閥、旋塞閥、球閥、蝶閥、止回閥、減壓閥安全閥、疏水閥、調節閥、底閥、過濾器、排污閥等，硬質合金加工。
