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(men)包括以上(shang)三種(zhong)閥(fa)門(men)，如果閥(fa)體等(deng)零(ling)部件(jian)(jian)(jian)(jian)是(shi)外(wai)購鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)或鍛(duan)件(jian)(jian)(jian)(jian)，進(jin)(jin)廠之(zhi)前(qian)都要進(jin)(jin)行(xing)嚴(yan)厲(li)的(de)查(cha)(cha)驗，通過查(cha)(cha)驗合格的(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)在(zai)進(jin)(jin)入(ru)(ru)車(che)間(jian)(jian)之(zhi)前(qian)會再次進(jin)(jin)行(xing)補焊(han)，意圖是(shi)對鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)上(shang)的(de)某一些(xie)缺點進(jin)(jin)行(xing)修(xiu)補。修(xiu)補后的(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)進(jin)(jin)入(ru)(ru)車(che)間(jian)(jian)，閥(fa)體，閥(fa)蓋或密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)等(deng)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)分別(bie)在(zai)特(te)定(ding)的(de)機床上(shang)進(jin)(jin)行(xing)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)。其間(jian)(jian)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)根據密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)方(fang)式(shi)分為硬密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)和軟(ruan)(ruan)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)的(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)，硬密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)是(shi)指密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)副的(de)兩(liang)邊均是(shi)金屬(shu)(shu)資(zi)料或較硬的(de)其它資(zi)料。這種(zhong)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)的(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)功(gong)能(neng)較差,但耐高(gao)溫,抗(kang)磨損(sun),機械功(gong)能(neng)好(hao)；軟(ruan)(ruan)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)是(shi)指密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)副的(de)兩(liang)邊一側(ce)是(shi)金屬(shu)(shu)資(zi)料,另一側(ce)是(shi)有彈性(xing)(xing)的(de)非金屬(shu)(shu)資(zi)料。這種(zhong)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)的(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)功(gong)能(neng)較好(hao),但不耐高(gao)溫,易(yi)磨損(sun),機械性(xing)(xing)較差。硬密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)方(fang)式(shi)的(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)，和其他鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)一樣，車(che)削加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)之(zhi)后直接進(jin)(jin)行(xing)鉆銑刨(bao)插加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)，去毛刺打磨，然(ran)后就可以清洗吹(chui)干(gan)，進(jin)(jin)行(xing)防銹處理后入(ru)(ru)庫等(deng)候拼(pin)裝。軟(ruan)(ruan)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)方(fang)式(shi)的(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)在(zai)車(che)削加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)之(zhi)后，還必須通過堆焊(han)、精加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)、鉆銑刨(bao)插加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)、去毛刺打磨和密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)面研磨之(zhi)后，才干(gan)清洗吹(chui)干(gan)防銹然(ran)后入(ru)(ru)庫等(deng)候拼(pin)裝。軟(ruan)(ruan)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)方(fang)式(shi)的(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)必須通過堆焊(han)的(de)原因是(shi)為了使(shi)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)外(wai)表取得耐磨，耐熱或耐蝕的(de)特(te)殊(shu)功(gong)能(neng)，添加(jia)(jia)(jia)外(wai)表硬度(du)和耐磨性(xing)(xing)，提高(gao)壽命運(yun)用(yong)。
