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(na)種閥(fa)門(men)包括以(yi)上三種閥(fa)門(men)，如果閥(fa)體等(deng)(deng)零(ling)部件(jian)(jian)(jian)(jian)是(shi)外購鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)或(huo)鍛件(jian)(jian)(jian)(jian)，進(jin)廠之(zhi)(zhi)前都要進(jin)行嚴厲的(de)(de)(de)查(cha)驗，通過(guo)查(cha)驗合格的(de)(de)(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)在(zai)(zai)進(jin)入(ru)車間(jian)之(zhi)(zhi)前會再次進(jin)行補焊，意圖是(shi)對鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)上的(de)(de)(de)某一(yi)些缺點進(jin)行修(xiu)補。修(xiu)補后(hou)的(de)(de)(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)進(jin)入(ru)車間(jian)，閥(fa)體，閥(fa)蓋(gai)或(huo)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)等(deng)(deng)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)分(fen)別在(zai)(zai)特定的(de)(de)(de)機(ji)床上進(jin)行加(jia)工(gong)(gong)。其(qi)(qi)間(jian)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(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)(mi)(mi)封(feng)(feng)方式(shi)分(fen)為硬(ying)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)和(he)(he)軟(ruan)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)的(de)(de)(de)加(jia)工(gong)(gong)，硬(ying)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)是(shi)指密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)副的(de)(de)(de)兩邊均是(shi)金屬(shu)資(zi)(zi)料(liao)(liao)或(huo)較(jiao)(jiao)硬(ying)的(de)(de)(de)其(qi)(qi)它資(zi)(zi)料(liao)(liao)。這(zhe)種密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)的(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)功能較(jiao)(jiao)差,但耐(nai)(nai)高(gao)溫(wen)(wen),抗磨(mo)損,機(ji)械(xie)功能好；軟(ruan)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)是(shi)指密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)副的(de)(de)(de)兩邊一(yi)側是(shi)金屬(shu)資(zi)(zi)料(liao)(liao),另(ling)一(yi)側是(shi)有彈性的(de)(de)(de)非金屬(shu)資(zi)(zi)料(liao)(liao)。這(zhe)種密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)的(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)功能較(jiao)(jiao)好,但不耐(nai)(nai)高(gao)溫(wen)(wen),易磨(mo)損,機(ji)械(xie)性較(jiao)(jiao)差。硬(ying)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)方式(shi)的(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)，和(he)(he)其(qi)(qi)他(ta)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)一(yi)樣，車削(xue)(xue)加(jia)工(gong)(gong)之(zhi)(zhi)后(hou)直接進(jin)行鉆銑(xian)刨(bao)(bao)插加(jia)工(gong)(gong)，去(qu)毛刺打磨(mo)，然后(hou)就可以(yi)清(qing)洗吹干(gan)，進(jin)行防(fang)銹處理后(hou)入(ru)庫等(deng)(deng)候(hou)拼(pin)(pin)裝。軟(ruan)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)方式(shi)的(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)在(zai)(zai)車削(xue)(xue)加(jia)工(gong)(gong)之(zhi)(zhi)后(hou)，還必須通過(guo)堆(dui)焊、精加(jia)工(gong)(gong)、鉆銑(xian)刨(bao)(bao)插加(jia)工(gong)(gong)、去(qu)毛刺打磨(mo)和(he)(he)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)面研(yan)磨(mo)之(zhi)(zhi)后(hou)，才干(gan)清(qing)洗吹干(gan)防(fang)銹然后(hou)入(ru)庫等(deng)(deng)候(hou)拼(pin)(pin)裝。軟(ruan)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)方式(shi)的(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)必須通過(guo)堆(dui)焊的(de)(de)(de)原因是(shi)為了使(shi)密(mi)(mi)(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)外表取得(de)耐(nai)(nai)磨(mo)，耐(nai)(nai)熱(re)或(huo)耐(nai)(nai)蝕(shi)的(de)(de)(de)特殊(shu)功能，添加(jia)外表硬(ying)度和(he)(he)耐(nai)(nai)磨(mo)性，提高(gao)壽命(ming)運用。
