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。
無論是(shi)哪種(zhong)閥(fa)門包括以上(shang)三種(zhong)閥(fa)門，如果閥(fa)體(ti)(ti)等(deng)零部(bu)件(jian)(jian)(jian)(jian)(jian)(jian)是(shi)外(wai)(wai)購鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)或(huo)鍛件(jian)(jian)(jian)(jian)(jian)(jian)，進(jin)(jin)廠之(zhi)前都要進(jin)(jin)行(xing)(xing)(xing)嚴厲的(de)(de)(de)(de)(de)查驗，通過查驗合格的(de)(de)(de)(de)(de)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)在(zai)進(jin)(jin)入車(che)間(jian)(jian)(jian)之(zhi)前會再次進(jin)(jin)行(xing)(xing)(xing)補焊(han)，意圖是(shi)對鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)上(shang)的(de)(de)(de)(de)(de)某一(yi)些缺點(dian)進(jin)(jin)行(xing)(xing)(xing)修補。修補后(hou)(hou)(hou)的(de)(de)(de)(de)(de)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)進(jin)(jin)入車(che)間(jian)(jian)(jian)，閥(fa)體(ti)(ti)，閥(fa)蓋或(huo)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)等(deng)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)分(fen)別在(zai)特(te)定的(de)(de)(de)(de)(de)機床(chuang)上(shang)進(jin)(jin)行(xing)(xing)(xing)加(jia)工(gong)。其(qi)間(jian)(jian)(jian)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)根據密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)方式(shi)(shi)分(fen)為硬(ying)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)和軟密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)的(de)(de)(de)(de)(de)加(jia)工(gong)，硬(ying)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)是(shi)指(zhi)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)副的(de)(de)(de)(de)(de)兩邊均是(shi)金屬(shu)資(zi)(zi)料或(huo)較硬(ying)的(de)(de)(de)(de)(de)其(qi)它(ta)資(zi)(zi)料。這種(zhong)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)的(de)(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)功能較差,但耐高(gao)溫(wen),抗磨(mo)損(sun),機械功能好；軟密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)是(shi)指(zhi)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)副的(de)(de)(de)(de)(de)兩邊一(yi)側(ce)是(shi)金屬(shu)資(zi)(zi)料,另一(yi)側(ce)是(shi)有彈(dan)性的(de)(de)(de)(de)(de)非(fei)金屬(shu)資(zi)(zi)料。這種(zhong)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)的(de)(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)功能較好,但不耐高(gao)溫(wen),易磨(mo)損(sun),機械性較差。硬(ying)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)方式(shi)(shi)的(de)(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)，和其(qi)他鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)一(yi)樣，車(che)削加(jia)工(gong)之(zhi)后(hou)(hou)(hou)直接進(jin)(jin)行(xing)(xing)(xing)鉆銑刨(bao)插(cha)加(jia)工(gong)，去毛刺(ci)打磨(mo)，然后(hou)(hou)(hou)就可以清(qing)洗吹干(gan)(gan)，進(jin)(jin)行(xing)(xing)(xing)防銹處理(li)后(hou)(hou)(hou)入庫等(deng)候(hou)拼(pin)裝(zhuang)。軟密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)方式(shi)(shi)的(de)(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)在(zai)車(che)削加(jia)工(gong)之(zhi)后(hou)(hou)(hou)，還必須通過堆(dui)焊(han)、精加(jia)工(gong)、鉆銑刨(bao)插(cha)加(jia)工(gong)、去毛刺(ci)打磨(mo)和密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)面(mian)研磨(mo)之(zhi)后(hou)(hou)(hou)，才干(gan)(gan)清(qing)洗吹干(gan)(gan)防銹然后(hou)(hou)(hou)入庫等(deng)候(hou)拼(pin)裝(zhuang)。軟密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)方式(shi)(shi)的(de)(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)必須通過堆(dui)焊(han)的(de)(de)(de)(de)(de)原因是(shi)為了使密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)外(wai)(wai)表取得耐磨(mo)，耐熱或(huo)耐蝕的(de)(de)(de)(de)(de)特(te)殊功能，添加(jia)外(wai)(wai)表硬(ying)度和耐磨(mo)性，提高(gao)壽命運用。
