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)哪種(zhong)閥門(men)包(bao)括以上三種(zhong)閥門(men)，如果閥體等(deng)(deng)零部件(jian)(jian)(jian)是(shi)(shi)外購(gou)鑄(zhu)件(jian)(jian)(jian)或(huo)鍛(duan)件(jian)(jian)(jian)，進(jin)(jin)(jin)廠之(zhi)(zhi)前(qian)都要進(jin)(jin)(jin)行(xing)嚴厲的(de)(de)查驗(yan)，通過(guo)(guo)查驗(yan)合(he)格的(de)(de)鑄(zhu)件(jian)(jian)(jian)在(zai)進(jin)(jin)(jin)入(ru)車(che)間之(zhi)(zhi)前(qian)會(hui)再次(ci)進(jin)(jin)(jin)行(xing)補焊(han)，意圖(tu)是(shi)(shi)對鑄(zhu)件(jian)(jian)(jian)上的(de)(de)某一(yi)些缺點進(jin)(jin)(jin)行(xing)修補。修補后(hou)的(de)(de)鑄(zhu)件(jian)(jian)(jian)進(jin)(jin)(jin)入(ru)車(che)間，閥體，閥蓋或(huo)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)等(deng)(deng)鑄(zhu)件(jian)(jian)(jian)分別在(zai)特(te)定的(de)(de)機(ji)床上進(jin)(jin)(jin)行(xing)加(jia)(jia)(jia)工(gong)。其(qi)間密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)根據(ju)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式分為硬(ying)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)和軟(ruan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)加(jia)(jia)(jia)工(gong)，硬(ying)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)是(shi)(shi)指(zhi)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副的(de)(de)兩邊均是(shi)(shi)金屬(shu)資料(liao)(liao)或(huo)較(jiao)硬(ying)的(de)(de)其(qi)它資料(liao)(liao)。這(zhe)(zhe)種(zhong)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)功(gong)(gong)能較(jiao)差,但耐(nai)高溫(wen),抗磨(mo)損,機(ji)械功(gong)(gong)能好；軟(ruan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)是(shi)(shi)指(zhi)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副的(de)(de)兩邊一(yi)側(ce)是(shi)(shi)金屬(shu)資料(liao)(liao),另一(yi)側(ce)是(shi)(shi)有(you)彈性的(de)(de)非金屬(shu)資料(liao)(liao)。這(zhe)(zhe)種(zhong)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)功(gong)(gong)能較(jiao)好,但不耐(nai)高溫(wen),易(yi)磨(mo)損,機(ji)械性較(jiao)差。硬(ying)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式的(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)，和其(qi)他鑄(zhu)件(jian)(jian)(jian)一(yi)樣，車(che)削(xue)加(jia)(jia)(jia)工(gong)之(zhi)(zhi)后(hou)直接進(jin)(jin)(jin)行(xing)鉆銑刨(bao)插(cha)加(jia)(jia)(jia)工(gong)，去(qu)毛刺打磨(mo)，然后(hou)就可以清洗吹(chui)干(gan)，進(jin)(jin)(jin)行(xing)防銹處理后(hou)入(ru)庫(ku)等(deng)(deng)候(hou)(hou)拼(pin)(pin)裝(zhuang)。軟(ruan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式的(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)在(zai)車(che)削(xue)加(jia)(jia)(jia)工(gong)之(zhi)(zhi)后(hou)，還必須(xu)通過(guo)(guo)堆焊(han)、精加(jia)(jia)(jia)工(gong)、鉆銑刨(bao)插(cha)加(jia)(jia)(jia)工(gong)、去(qu)毛刺打磨(mo)和密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)面(mian)研(yan)磨(mo)之(zhi)(zhi)后(hou)，才干(gan)清洗吹(chui)干(gan)防銹然后(hou)入(ru)庫(ku)等(deng)(deng)候(hou)(hou)拼(pin)(pin)裝(zhuang)。軟(ruan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式的(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)必須(xu)通過(guo)(guo)堆焊(han)的(de)(de)原因(yin)是(shi)(shi)為了(le)使密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)外表(biao)取得耐(nai)磨(mo)，耐(nai)熱或(huo)耐(nai)蝕的(de)(de)特(te)殊功(gong)(gong)能，添加(jia)(jia)(jia)外表(biao)硬(ying)度(du)和耐(nai)磨(mo)性，提高壽命運用。
