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)(shi)哪種閥(fa)(fa)門包括以(yi)上(shang)三種閥(fa)(fa)門，如果(guo)閥(fa)(fa)體等(deng)(deng)零部件(jian)(jian)(jian)(jian)(jian)是(shi)(shi)(shi)外(wai)購鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)或鍛件(jian)(jian)(jian)(jian)(jian)，進(jin)廠之前(qian)都要進(jin)行嚴厲的(de)(de)(de)(de)查驗，通過查驗合格的(de)(de)(de)(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)在進(jin)入車(che)間之前(qian)會再次進(jin)行補(bu)焊，意圖是(shi)(shi)(shi)對鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)上(shang)的(de)(de)(de)(de)某(mou)一(yi)(yi)些缺點(dian)進(jin)行修補(bu)。修補(bu)后(hou)的(de)(de)(de)(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)進(jin)入車(che)間，閥(fa)(fa)體，閥(fa)(fa)蓋或密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)等(deng)(deng)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)分別在特定(ding)的(de)(de)(de)(de)機(ji)床上(shang)進(jin)行加工。其間密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)根據密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式分為(wei)(wei)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)(shi)指密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副的(de)(de)(de)(de)兩邊均是(shi)(shi)(shi)金屬資料或較(jiao)硬(ying)(ying)的(de)(de)(de)(de)其它資料。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(jiao)差,但耐(nai)(nai)高溫,抗磨(mo)(mo)(mo)損,機(ji)械功(gong)能好；軟密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)是(shi)(shi)(shi)指密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副的(de)(de)(de)(de)兩邊一(yi)(yi)側(ce)是(shi)(shi)(shi)金屬資料,另一(yi)(yi)側(ce)是(shi)(shi)(shi)有彈性(xing)的(de)(de)(de)(de)非金屬資料。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(jiao)好,但不耐(nai)(nai)高溫,易磨(mo)(mo)(mo)損,機(ji)械性(xing)較(jiao)差。硬(ying)(ying)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)，和(he)其他鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)一(yi)(yi)樣，車(che)削(xue)加工之后(hou)直接進(jin)行鉆(zhan)銑刨插加工，去毛(mao)刺打(da)磨(mo)(mo)(mo)，然后(hou)就(jiu)可(ke)以(yi)清洗吹(chui)干(gan)，進(jin)行防(fang)銹(xiu)處理(li)后(hou)入庫(ku)等(deng)(deng)候拼裝(zhuang)。軟密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄(zhu)(zhu)(zhu)件(jian)(jian)(jian)(jian)(jian)在車(che)削(xue)加工之后(hou)，還必(bi)須(xu)通過堆(dui)焊、精加工、鉆(zhan)銑刨插加工、去毛(mao)刺打(da)磨(mo)(mo)(mo)和(he)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)面研磨(mo)(mo)(mo)之后(hou)，才干(gan)清洗吹(chui)干(gan)防(fang)銹(xiu)然后(hou)入庫(ku)等(deng)(deng)候拼裝(zhuang)。軟密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方式的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)必(bi)須(xu)通過堆(dui)焊的(de)(de)(de)(de)原因是(shi)(shi)(shi)為(wei)(wei)了使密(mi)(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)(jian)外(wai)表取得耐(nai)(nai)磨(mo)(mo)(mo)，耐(nai)(nai)熱或耐(nai)(nai)蝕(shi)的(de)(de)(de)(de)特殊功(gong)能，添加外(wai)表硬(ying)(ying)度和(he)耐(nai)(nai)磨(mo)(mo)(mo)性(xing)，提高壽命運(yun)用。
