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)哪種閥(fa)(fa)門包(bao)括以上三種閥(fa)(fa)門,如果閥(fa)(fa)體等(deng)(deng)零部件(jian)(jian)(jian)(jian)(jian)是(shi)外購(gou)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)或(huo)鍛件(jian)(jian)(jian)(jian)(jian),進(jin)廠之前(qian)都要(yao)進(jin)行(xing)嚴(yan)厲的(de)(de)(de)查驗,通(tong)過(guo)查驗合格的(de)(de)(de)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)在進(jin)入(ru)車(che)間(jian)(jian)之前(qian)會再次進(jin)行(xing)補焊,意圖是(shi)對鑄(zhu)件(jian)(jian)(jian)(jian)(jian)上的(de)(de)(de)某一些缺點進(jin)行(xing)修補。修補后(hou)的(de)(de)(de)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)進(jin)入(ru)車(che)間(jian)(jian),閥(fa)(fa)體,閥(fa)(fa)蓋或(huo)密(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)(jian)等(deng)(deng)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)分別在特(te)定的(de)(de)(de)機(ji)床(chuang)上進(jin)行(xing)加工(gong)(gong)。其(qi)間(jian)(jian)密(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)根(gen)據密(mi)(mi)(mi)(mi)封(feng)(feng)方(fang)式(shi)(shi)分為硬(ying)(ying)密(mi)(mi)(mi)(mi)封(feng)(feng)和(he)軟密(mi)(mi)(mi)(mi)封(feng)(feng)的(de)(de)(de)加工(gong)(gong),硬(ying)(ying)密(mi)(mi)(mi)(mi)封(feng)(feng)是(shi)指密(mi)(mi)(mi)(mi)封(feng)(feng)副的(de)(de)(de)兩(liang)(liang)邊(bian)均(jun)是(shi)金屬(shu)資料(liao)或(huo)較硬(ying)(ying)的(de)(de)(de)其(qi)它資料(liao)。這(zhe)(zhe)種密(mi)(mi)(mi)(mi)封(feng)(feng)的(de)(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)功能較差(cha),但(dan)耐(nai)(nai)(nai)高(gao)溫(wen),抗磨(mo)(mo)損(sun),機(ji)械(xie)功能好(hao);軟密(mi)(mi)(mi)(mi)封(feng)(feng)是(shi)指密(mi)(mi)(mi)(mi)封(feng)(feng)副的(de)(de)(de)兩(liang)(liang)邊(bian)一側是(shi)金屬(shu)資料(liao),另一側是(shi)有彈性的(de)(de)(de)非(fei)金屬(shu)資料(liao)。這(zhe)(zhe)種密(mi)(mi)(mi)(mi)封(feng)(feng)的(de)(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)功能較好(hao),但(dan)不耐(nai)(nai)(nai)高(gao)溫(wen),易磨(mo)(mo)損(sun),機(ji)械(xie)性較差(cha)。硬(ying)(ying)密(mi)(mi)(mi)(mi)封(feng)(feng)方(fang)式(shi)(shi)的(de)(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)(jian)(jian),和(he)其(qi)他鑄(zhu)件(jian)(jian)(jian)(jian)(jian)一樣,車(che)削加工(gong)(gong)之后(hou)直接進(jin)行(xing)鉆(zhan)銑(xian)刨(bao)插(cha)加工(gong)(gong),去毛刺(ci)打(da)磨(mo)(mo),然(ran)(ran)后(hou)就可以清洗吹干(gan),進(jin)行(xing)防銹處理(li)后(hou)入(ru)庫等(deng)(deng)候拼(pin)裝。軟密(mi)(mi)(mi)(mi)封(feng)(feng)方(fang)式(shi)(shi)的(de)(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)(jian)鑄(zhu)件(jian)(jian)(jian)(jian)(jian)在車(che)削加工(gong)(gong)之后(hou),還必須通(tong)過(guo)堆焊、精加工(gong)(gong)、鉆(zhan)銑(xian)刨(bao)插(cha)加工(gong)(gong)、去毛刺(ci)打(da)磨(mo)(mo)和(he)密(mi)(mi)(mi)(mi)封(feng)(feng)面研磨(mo)(mo)之后(hou),才干(gan)清洗吹干(gan)防銹然(ran)(ran)后(hou)入(ru)庫等(deng)(deng)候拼(pin)裝。軟密(mi)(mi)(mi)(mi)封(feng)(feng)方(fang)式(shi)(shi)的(de)(de)(de)密(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)(jian)必須通(tong)過(guo)堆焊的(de)(de)(de)原因是(shi)為了使密(mi)(mi)(mi)(mi)封(feng)(feng)件(jian)(jian)(jian)(jian)(jian)外表取得(de)耐(nai)(nai)(nai)磨(mo)(mo),耐(nai)(nai)(nai)熱(re)或(huo)耐(nai)(nai)(nai)蝕的(de)(de)(de)特(te)殊功能,添加外表硬(ying)(ying)度和(he)耐(nai)(nai)(nai)磨(mo)(mo)性,提高(gao)壽命運用。
