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)哪種(zhong)閥(fa)門(men)包括以上(shang)三種(zhong)閥(fa)門(men)，如果閥(fa)體等(deng)零部(bu)件(jian)(jian)(jian)(jian)是(shi)外(wai)購鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)或鍛件(jian)(jian)(jian)(jian)，進(jin)(jin)(jin)(jin)(jin)廠之前(qian)(qian)都要進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)(xing)嚴厲(li)的(de)(de)查(cha)驗(yan)，通(tong)(tong)過查(cha)驗(yan)合(he)格的(de)(de)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)在(zai)進(jin)(jin)(jin)(jin)(jin)入車(che)間(jian)之前(qian)(qian)會再次進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)(xing)補焊，意圖是(shi)對鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)上(shang)的(de)(de)某(mou)一(yi)(yi)(yi)些缺點(dian)進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)(xing)修(xiu)(xiu)補。修(xiu)(xiu)補后(hou)(hou)(hou)的(de)(de)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)進(jin)(jin)(jin)(jin)(jin)入車(che)間(jian)，閥(fa)體，閥(fa)蓋或密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)等(deng)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)分別在(zai)特(te)定的(de)(de)機(ji)床上(shang)進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)(xing)加(jia)工。其(qi)間(jian)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)根(gen)據密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方(fang)(fang)式分為硬(ying)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)和軟(ruan)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)的(de)(de)加(jia)工，硬(ying)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)是(shi)指密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)副的(de)(de)兩邊(bian)均是(shi)金(jin)屬資料(liao)或較(jiao)硬(ying)的(de)(de)其(qi)它(ta)資料(liao)。這種(zhong)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)的(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)功(gong)能(neng)較(jiao)差,但(dan)耐(nai)(nai)高(gao)(gao)(gao)溫,抗磨(mo)(mo)損,機(ji)械功(gong)能(neng)好；軟(ruan)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)是(shi)指密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)副的(de)(de)兩邊(bian)一(yi)(yi)(yi)側是(shi)金(jin)屬資料(liao),另一(yi)(yi)(yi)側是(shi)有彈性(xing)的(de)(de)非金(jin)屬資料(liao)。這種(zhong)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)的(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)功(gong)能(neng)較(jiao)好,但(dan)不耐(nai)(nai)高(gao)(gao)(gao)溫,易磨(mo)(mo)損,機(ji)械性(xing)較(jiao)差。硬(ying)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方(fang)(fang)式的(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)，和其(qi)他鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)一(yi)(yi)(yi)樣，車(che)削(xue)加(jia)工之后(hou)(hou)(hou)直接進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)(xing)鉆(zhan)銑刨插(cha)加(jia)工，去(qu)毛刺打磨(mo)(mo)，然后(hou)(hou)(hou)就可(ke)以清(qing)洗(xi)吹(chui)干，進(jin)(jin)(jin)(jin)(jin)行(xing)(xing)(xing)防(fang)銹處理后(hou)(hou)(hou)入庫等(deng)候拼(pin)裝(zhuang)。軟(ruan)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方(fang)(fang)式的(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)(jian)(jian)在(zai)車(che)削(xue)加(jia)工之后(hou)(hou)(hou)，還(huan)必須通(tong)(tong)過堆(dui)焊、精加(jia)工、鉆(zhan)銑刨插(cha)加(jia)工、去(qu)毛刺打磨(mo)(mo)和密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)面(mian)研(yan)磨(mo)(mo)之后(hou)(hou)(hou)，才干清(qing)洗(xi)吹(chui)干防(fang)銹然后(hou)(hou)(hou)入庫等(deng)候拼(pin)裝(zhuang)。軟(ruan)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方(fang)(fang)式的(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)必須通(tong)(tong)過堆(dui)焊的(de)(de)原因是(shi)為了(le)使密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)(jian)(jian)(jian)外(wai)表取得耐(nai)(nai)磨(mo)(mo)，耐(nai)(nai)熱或耐(nai)(nai)蝕的(de)(de)特(te)殊功(gong)能(neng)，添加(jia)外(wai)表硬(ying)度和耐(nai)(nai)磨(mo)(mo)性(xing)，提高(gao)(gao)(gao)壽命運用。
