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)哪種閥門包括(kuo)以上(shang)三種閥門，如果閥體等(deng)零部件(jian)(jian)是(shi)(shi)外(wai)購鑄(zhu)(zhu)件(jian)(jian)或(huo)鍛(duan)件(jian)(jian)，進(jin)(jin)廠之(zhi)前(qian)都要進(jin)(jin)行(xing)嚴厲的(de)(de)(de)(de)查驗，通過查驗合格(ge)的(de)(de)(de)(de)鑄(zhu)(zhu)件(jian)(jian)在(zai)進(jin)(jin)入(ru)車(che)(che)間之(zhi)前(qian)會(hui)再次進(jin)(jin)行(xing)補焊(han)，意圖(tu)是(shi)(shi)對鑄(zhu)(zhu)件(jian)(jian)上(shang)的(de)(de)(de)(de)某一(yi)(yi)些缺點進(jin)(jin)行(xing)修補。修補后(hou)(hou)(hou)的(de)(de)(de)(de)鑄(zhu)(zhu)件(jian)(jian)進(jin)(jin)入(ru)車(che)(che)間，閥體，閥蓋或(huo)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)等(deng)鑄(zhu)(zhu)件(jian)(jian)分別在(zai)特定的(de)(de)(de)(de)機床(chuang)上(shang)進(jin)(jin)行(xing)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)。其間密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)根據密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方(fang)式(shi)(shi)分為(wei)硬密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)和軟(ruan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)，硬密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)是(shi)(shi)指密(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)屬資(zi)料或(huo)較(jiao)硬的(de)(de)(de)(de)其它資(zi)料。這種密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)功能(neng)較(jiao)差(cha)(cha),但(dan)耐高溫,抗磨(mo)(mo)(mo)(mo)損,機械功能(neng)好；軟(ruan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)是(shi)(shi)指密(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)屬資(zi)料,另一(yi)(yi)側(ce)是(shi)(shi)有(you)彈性(xing)(xing)的(de)(de)(de)(de)非金(jin)屬資(zi)料。這種密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)功能(neng)較(jiao)好,但(dan)不(bu)耐高溫,易磨(mo)(mo)(mo)(mo)損,機械性(xing)(xing)較(jiao)差(cha)(cha)。硬密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方(fang)式(shi)(shi)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)，和其他鑄(zhu)(zhu)件(jian)(jian)一(yi)(yi)樣(yang)，車(che)(che)削(xue)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)之(zhi)后(hou)(hou)(hou)直接進(jin)(jin)行(xing)鉆銑刨插加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)，去毛刺打磨(mo)(mo)(mo)(mo)，然后(hou)(hou)(hou)就可以清洗吹干(gan)，進(jin)(jin)行(xing)防銹處理后(hou)(hou)(hou)入(ru)庫等(deng)候拼裝。軟(ruan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方(fang)式(shi)(shi)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)鑄(zhu)(zhu)件(jian)(jian)在(zai)車(che)(che)削(xue)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)之(zhi)后(hou)(hou)(hou)，還必須通過堆(dui)焊(han)、精加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)、鉆銑刨插加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)、去毛刺打磨(mo)(mo)(mo)(mo)和密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)面研磨(mo)(mo)(mo)(mo)之(zhi)后(hou)(hou)(hou)，才干(gan)清洗吹干(gan)防銹然后(hou)(hou)(hou)入(ru)庫等(deng)候拼裝。軟(ruan)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)方(fang)式(shi)(shi)的(de)(de)(de)(de)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)必須通過堆(dui)焊(han)的(de)(de)(de)(de)原因是(shi)(shi)為(wei)了使密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)件(jian)(jian)外(wai)表取得耐磨(mo)(mo)(mo)(mo)，耐熱或(huo)耐蝕的(de)(de)(de)(de)特殊(shu)功能(neng)，添加(jia)(jia)(jia)(jia)外(wai)表硬度和耐磨(mo)(mo)(mo)(mo)性(xing)(xing)，提(ti)高壽命運(yun)用。
