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)(shi)(shi)(shi)(shi)哪種閥門包括以(yi)上(shang)三種閥門，如(ru)果閥體等零部件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)是(shi)(shi)(shi)(shi)(shi)外購鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)或(huo)鍛件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)，進(jin)廠之(zhi)前都要進(jin)行嚴厲的(de)(de)(de)(de)(de)(de)查驗，通過查驗合格的(de)(de)(de)(de)(de)(de)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)在(zai)進(jin)入(ru)車間(jian)之(zhi)前會再次(ci)進(jin)行補焊(han)，意圖是(shi)(shi)(shi)(shi)(shi)對鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)上(shang)的(de)(de)(de)(de)(de)(de)某(mou)一(yi)些缺(que)點進(jin)行修補。修補后(hou)的(de)(de)(de)(de)(de)(de)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)進(jin)入(ru)車間(jian)，閥體，閥蓋或(huo)密(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)等鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)分別在(zai)特定的(de)(de)(de)(de)(de)(de)機床(chuang)上(shang)進(jin)行加(jia)(jia)(jia)工。其間(jian)密(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)根據密(mi)(mi)封(feng)(feng)(feng)方(fang)式(shi)分為硬(ying)(ying)密(mi)(mi)封(feng)(feng)(feng)和(he)(he)軟密(mi)(mi)封(feng)(feng)(feng)的(de)(de)(de)(de)(de)(de)加(jia)(jia)(jia)工，硬(ying)(ying)密(mi)(mi)封(feng)(feng)(feng)是(shi)(shi)(shi)(shi)(shi)指密(mi)(mi)封(feng)(feng)(feng)副(fu)(fu)的(de)(de)(de)(de)(de)(de)兩邊(bian)均(jun)是(shi)(shi)(shi)(shi)(shi)金(jin)屬(shu)資料(liao)(liao)或(huo)較硬(ying)(ying)的(de)(de)(de)(de)(de)(de)其它資料(liao)(liao)。這(zhe)種密(mi)(mi)封(feng)(feng)(feng)的(de)(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)(feng)功(gong)(gong)能(neng)較差,但耐高溫,抗磨(mo)(mo)損,機械(xie)功(gong)(gong)能(neng)好；軟密(mi)(mi)封(feng)(feng)(feng)是(shi)(shi)(shi)(shi)(shi)指密(mi)(mi)封(feng)(feng)(feng)副(fu)(fu)的(de)(de)(de)(de)(de)(de)兩邊(bian)一(yi)側是(shi)(shi)(shi)(shi)(shi)金(jin)屬(shu)資料(liao)(liao),另一(yi)側是(shi)(shi)(shi)(shi)(shi)有彈性(xing)的(de)(de)(de)(de)(de)(de)非金(jin)屬(shu)資料(liao)(liao)。這(zhe)種密(mi)(mi)封(feng)(feng)(feng)的(de)(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)(feng)功(gong)(gong)能(neng)較好,但不耐高溫,易磨(mo)(mo)損,機械(xie)性(xing)較差。硬(ying)(ying)密(mi)(mi)封(feng)(feng)(feng)方(fang)式(shi)的(de)(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)，和(he)(he)其他鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)一(yi)樣，車削(xue)加(jia)(jia)(jia)工之(zhi)后(hou)直接進(jin)行鉆(zhan)銑(xian)刨(bao)插加(jia)(jia)(jia)工，去(qu)毛刺(ci)打磨(mo)(mo)，然后(hou)就可以(yi)清(qing)(qing)洗吹(chui)干，進(jin)行防銹處理后(hou)入(ru)庫等候拼(pin)裝(zhuang)。軟密(mi)(mi)封(feng)(feng)(feng)方(fang)式(shi)的(de)(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)在(zai)車削(xue)加(jia)(jia)(jia)工之(zhi)后(hou)，還必(bi)須通過堆焊(han)、精加(jia)(jia)(jia)工、鉆(zhan)銑(xian)刨(bao)插加(jia)(jia)(jia)工、去(qu)毛刺(ci)打磨(mo)(mo)和(he)(he)密(mi)(mi)封(feng)(feng)(feng)面研磨(mo)(mo)之(zhi)后(hou)，才干清(qing)(qing)洗吹(chui)干防銹然后(hou)入(ru)庫等候拼(pin)裝(zhuang)。軟密(mi)(mi)封(feng)(feng)(feng)方(fang)式(shi)的(de)(de)(de)(de)(de)(de)密(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)必(bi)須通過堆焊(han)的(de)(de)(de)(de)(de)(de)原因是(shi)(shi)(shi)(shi)(shi)為了(le)使密(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)(jian)(jian)(jian)外表取得耐磨(mo)(mo)，耐熱或(huo)耐蝕的(de)(de)(de)(de)(de)(de)特殊功(gong)(gong)能(neng)，添加(jia)(jia)(jia)外表硬(ying)(ying)度和(he)(he)耐磨(mo)(mo)性(xing)，提高壽命運用。
