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(lun)是(shi)(shi)哪種閥門(men)包(bao)括以(yi)(yi)上(shang)三種閥門(men)，如果閥體等零部件(jian)是(shi)(shi)外(wai)購鑄(zhu)(zhu)(zhu)(zhu)件(jian)或(huo)鍛件(jian)，進(jin)(jin)(jin)廠(chang)之(zhi)(zhi)前都要(yao)進(jin)(jin)(jin)行嚴厲的(de)(de)查(cha)驗，通(tong)過查(cha)驗合(he)格(ge)的(de)(de)鑄(zhu)(zhu)(zhu)(zhu)件(jian)在進(jin)(jin)(jin)入車間之(zhi)(zhi)前會再(zai)次(ci)進(jin)(jin)(jin)行補(bu)(bu)(bu)焊(han)，意(yi)圖是(shi)(shi)對鑄(zhu)(zhu)(zhu)(zhu)件(jian)上(shang)的(de)(de)某一(yi)些缺點進(jin)(jin)(jin)行修補(bu)(bu)(bu)。修補(bu)(bu)(bu)后(hou)的(de)(de)鑄(zhu)(zhu)(zhu)(zhu)件(jian)進(jin)(jin)(jin)入車間，閥體，閥蓋(gai)或(huo)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)等鑄(zhu)(zhu)(zhu)(zhu)件(jian)分(fen)別在特定(ding)的(de)(de)機(ji)床上(shang)進(jin)(jin)(jin)行加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)。其(qi)間密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)鑄(zhu)(zhu)(zhu)(zhu)件(jian)根據(ju)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方式(shi)分(fen)為(wei)硬密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)和軟(ruan)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)的(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)，硬密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)是(shi)(shi)指密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)副的(de)(de)兩(liang)邊均(jun)是(shi)(shi)金屬資(zi)(zi)料(liao)或(huo)較硬的(de)(de)其(qi)它資(zi)(zi)料(liao)。這(zhe)種密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)的(de)(de)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)功能(neng)(neng)較差,但(dan)耐(nai)高(gao)溫(wen),抗磨(mo)(mo)損,機(ji)械功能(neng)(neng)好(hao)；軟(ruan)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)是(shi)(shi)指密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)副的(de)(de)兩(liang)邊一(yi)側(ce)是(shi)(shi)金屬資(zi)(zi)料(liao),另一(yi)側(ce)是(shi)(shi)有彈性(xing)的(de)(de)非金屬資(zi)(zi)料(liao)。這(zhe)種密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)的(de)(de)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)功能(neng)(neng)較好(hao),但(dan)不耐(nai)高(gao)溫(wen),易磨(mo)(mo)損,機(ji)械性(xing)較差。硬密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方式(shi)的(de)(de)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)鑄(zhu)(zhu)(zhu)(zhu)件(jian)，和其(qi)他鑄(zhu)(zhu)(zhu)(zhu)件(jian)一(yi)樣，車削加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)之(zhi)(zhi)后(hou)直接進(jin)(jin)(jin)行鉆銑(xian)刨插(cha)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)，去毛(mao)刺打磨(mo)(mo)，然后(hou)就可以(yi)(yi)清(qing)(qing)洗吹干(gan)(gan)，進(jin)(jin)(jin)行防銹處理(li)后(hou)入庫等候拼(pin)裝。軟(ruan)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方式(shi)的(de)(de)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)鑄(zhu)(zhu)(zhu)(zhu)件(jian)在車削加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)之(zhi)(zhi)后(hou)，還必須通(tong)過堆焊(han)、精加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)、鉆銑(xian)刨插(cha)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)、去毛(mao)刺打磨(mo)(mo)和密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)面(mian)研磨(mo)(mo)之(zhi)(zhi)后(hou)，才干(gan)(gan)清(qing)(qing)洗吹干(gan)(gan)防銹然后(hou)入庫等候拼(pin)裝。軟(ruan)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方式(shi)的(de)(de)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)必須通(tong)過堆焊(han)的(de)(de)原因是(shi)(shi)為(wei)了使(shi)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)外(wai)表取得耐(nai)磨(mo)(mo)，耐(nai)熱或(huo)耐(nai)蝕的(de)(de)特殊功能(neng)(neng)，添加(jia)(jia)(jia)外(wai)表硬度和耐(nai)磨(mo)(mo)性(xing)，提高(gao)壽命運用。
