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)哪種閥門包括(kuo)以上(shang)三種閥門，如果閥體等(deng)零部件(jian)(jian)(jian)是(shi)(shi)外(wai)購鑄件(jian)(jian)(jian)或鍛(duan)件(jian)(jian)(jian)，進(jin)(jin)廠之前(qian)都(dou)要(yao)進(jin)(jin)行(xing)(xing)(xing)嚴(yan)厲的(de)(de)(de)(de)查(cha)驗(yan)，通過查(cha)驗(yan)合格的(de)(de)(de)(de)鑄件(jian)(jian)(jian)在進(jin)(jin)入(ru)車(che)(che)(che)間(jian)(jian)之前(qian)會再次進(jin)(jin)行(xing)(xing)(xing)補(bu)焊(han)，意圖(tu)是(shi)(shi)對鑄件(jian)(jian)(jian)上(shang)的(de)(de)(de)(de)某(mou)一(yi)(yi)些缺點進(jin)(jin)行(xing)(xing)(xing)修補(bu)。修補(bu)后(hou)的(de)(de)(de)(de)鑄件(jian)(jian)(jian)進(jin)(jin)入(ru)車(che)(che)(che)間(jian)(jian)，閥體，閥蓋或密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)等(deng)鑄件(jian)(jian)(jian)分(fen)別在特(te)定的(de)(de)(de)(de)機床上(shang)進(jin)(jin)行(xing)(xing)(xing)加工。其間(jian)(jian)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)鑄件(jian)(jian)(jian)根據密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式(shi)分(fen)為硬(ying)(ying)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)和(he)軟密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)加工，硬(ying)(ying)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)是(shi)(shi)指密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副的(de)(de)(de)(de)兩邊(bian)均是(shi)(shi)金(jin)屬(shu)(shu)資料(liao)(liao)或較硬(ying)(ying)的(de)(de)(de)(de)其它資料(liao)(liao)。這種密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)功(gong)能較差,但耐高(gao)溫,抗磨(mo)損,機械功(gong)能好；軟密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)是(shi)(shi)指密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副的(de)(de)(de)(de)兩邊(bian)一(yi)(yi)側(ce)是(shi)(shi)金(jin)屬(shu)(shu)資料(liao)(liao),另一(yi)(yi)側(ce)是(shi)(shi)有彈性的(de)(de)(de)(de)非金(jin)屬(shu)(shu)資料(liao)(liao)。這種密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)功(gong)能較好,但不耐高(gao)溫,易(yi)磨(mo)損,機械性較差。硬(ying)(ying)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式(shi)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)鑄件(jian)(jian)(jian)，和(he)其他鑄件(jian)(jian)(jian)一(yi)(yi)樣，車(che)(che)(che)削(xue)加工之后(hou)直接進(jin)(jin)行(xing)(xing)(xing)鉆銑(xian)(xian)刨(bao)插加工，去毛(mao)刺打(da)磨(mo)，然(ran)后(hou)就(jiu)可(ke)以清(qing)洗吹(chui)干(gan)，進(jin)(jin)行(xing)(xing)(xing)防銹處理(li)后(hou)入(ru)庫等(deng)候(hou)拼裝。軟密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式(shi)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)鑄件(jian)(jian)(jian)在車(che)(che)(che)削(xue)加工之后(hou)，還必(bi)須通過堆(dui)焊(han)、精(jing)加工、鉆銑(xian)(xian)刨(bao)插加工、去毛(mao)刺打(da)磨(mo)和(he)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)面研磨(mo)之后(hou)，才干(gan)清(qing)洗吹(chui)干(gan)防銹然(ran)后(hou)入(ru)庫等(deng)候(hou)拼裝。軟密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式(shi)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)必(bi)須通過堆(dui)焊(han)的(de)(de)(de)(de)原因是(shi)(shi)為了使密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)外(wai)表取得耐磨(mo)，耐熱(re)或耐蝕(shi)的(de)(de)(de)(de)特(te)殊功(gong)能，添加外(wai)表硬(ying)(ying)度(du)和(he)耐磨(mo)性，提高(gao)壽命運用。
