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)閥門包(bao)括以上三種(zhong)閥門，如果閥體等(deng)(deng)零部件(jian)(jian)(jian)(jian)(jian)是(shi)外(wai)購(gou)鑄件(jian)(jian)(jian)(jian)(jian)或(huo)(huo)鍛件(jian)(jian)(jian)(jian)(jian)，進(jin)(jin)(jin)廠之(zhi)前都要進(jin)(jin)(jin)行(xing)嚴(yan)厲的(de)(de)查(cha)驗(yan)，通(tong)過(guo)查(cha)驗(yan)合(he)格的(de)(de)鑄件(jian)(jian)(jian)(jian)(jian)在(zai)(zai)進(jin)(jin)(jin)入車(che)間之(zhi)前會再次進(jin)(jin)(jin)行(xing)補(bu)焊(han)，意圖是(shi)對鑄件(jian)(jian)(jian)(jian)(jian)上的(de)(de)某一些缺(que)點進(jin)(jin)(jin)行(xing)修補(bu)。修補(bu)后(hou)(hou)的(de)(de)鑄件(jian)(jian)(jian)(jian)(jian)進(jin)(jin)(jin)入車(che)間，閥體，閥蓋或(huo)(huo)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)等(deng)(deng)鑄件(jian)(jian)(jian)(jian)(jian)分別在(zai)(zai)特定的(de)(de)機(ji)床上進(jin)(jin)(jin)行(xing)加工(gong)(gong)。其間密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄件(jian)(jian)(jian)(jian)(jian)根據密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)方(fang)式(shi)分為硬密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)和軟(ruan)(ruan)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)的(de)(de)加工(gong)(gong)，硬密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)是(shi)指(zhi)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)副的(de)(de)兩(liang)邊(bian)均(jun)是(shi)金(jin)屬(shu)資料(liao)(liao)或(huo)(huo)較(jiao)硬的(de)(de)其它資料(liao)(liao)。這種(zhong)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)的(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)功(gong)能較(jiao)差(cha)(cha),但耐(nai)(nai)(nai)(nai)高(gao)溫(wen),抗(kang)磨(mo)損,機(ji)械功(gong)能好(hao)；軟(ruan)(ruan)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)是(shi)指(zhi)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)副的(de)(de)兩(liang)邊(bian)一側是(shi)金(jin)屬(shu)資料(liao)(liao),另一側是(shi)有彈性(xing)的(de)(de)非金(jin)屬(shu)資料(liao)(liao)。這種(zhong)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)的(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)功(gong)能較(jiao)好(hao),但不耐(nai)(nai)(nai)(nai)高(gao)溫(wen),易(yi)磨(mo)損,機(ji)械性(xing)較(jiao)差(cha)(cha)。硬密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)方(fang)式(shi)的(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄件(jian)(jian)(jian)(jian)(jian)，和其他鑄件(jian)(jian)(jian)(jian)(jian)一樣，車(che)削加工(gong)(gong)之(zhi)后(hou)(hou)直接進(jin)(jin)(jin)行(xing)鉆銑刨(bao)插加工(gong)(gong)，去毛刺打磨(mo)，然后(hou)(hou)就可以清洗(xi)吹干，進(jin)(jin)(jin)行(xing)防銹(xiu)處理后(hou)(hou)入庫等(deng)(deng)候(hou)拼(pin)裝(zhuang)。軟(ruan)(ruan)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)方(fang)式(shi)的(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄件(jian)(jian)(jian)(jian)(jian)在(zai)(zai)車(che)削加工(gong)(gong)之(zhi)后(hou)(hou)，還必須通(tong)過(guo)堆(dui)焊(han)、精加工(gong)(gong)、鉆銑刨(bao)插加工(gong)(gong)、去毛刺打磨(mo)和密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)面(mian)研磨(mo)之(zhi)后(hou)(hou)，才干清洗(xi)吹干防銹(xiu)然后(hou)(hou)入庫等(deng)(deng)候(hou)拼(pin)裝(zhuang)。軟(ruan)(ruan)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)方(fang)式(shi)的(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)必須通(tong)過(guo)堆(dui)焊(han)的(de)(de)原因是(shi)為了使密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)外(wai)表(biao)取得耐(nai)(nai)(nai)(nai)磨(mo)，耐(nai)(nai)(nai)(nai)熱或(huo)(huo)耐(nai)(nai)(nai)(nai)蝕(shi)的(de)(de)特殊(shu)功(gong)能，添(tian)加外(wai)表(biao)硬度和耐(nai)(nai)(nai)(nai)磨(mo)性(xing)，提(ti)高(gao)壽命運用。
