異(yi)徑(jing)三(san)通管(guan)件的(de)生產(chan)工藝:在管(guan)道(dao)上(shang)安置頂(ding)(ding)出(chu)裝置,其(qi)裝置包括(kuo)金屬(shu)棒(bang),頂(ding)(ding)壓(ya)器,換向(xiang)器,支架等;將金屬(shu)棒(bang)加(jia)(jia)熱,利(li)用千斤頂(ding)(ding)及金屬(shu)棒(bang)向(xiang)外頂(ding)(ding)出(chu)時,管(guan)壁材料自然(ran)向(xiang)外翻(fan)出(chu)形(xing)成(cheng)的(de)異(yi)徑(jing)三(san)通毛坯;然(ran)后將一定長(chang)度(du)相應(ying)規格的(de)管(guan)段焊接在頂(ding)(ding)出(chu)形(xing)成(cheng)的(de)異(yi)徑(jing)三(san)通毛坯上(shang),生產(chan)出(chu)最終產(chan)品.在管(guan)道(dao)要(yao)加(jia)(jia)工異(yi)徑(jing)三(san)通處(chu)上(shang)作標記,并將標記處(chu)打(da)穿。

普通橡(xiang)膠(jiao)墊片(pian)適(shi)用于(yu)(yu)溫(wen)度低(di)于(yu)(yu)120℃的(de)(de)(de)場合;石(shi)棉(mian)(mian)橡(xiang)膠(jiao)墊片(pian)適(shi)用于(yu)(yu)對(dui)水蒸氣溫(wen)度低(di)于(yu)(yu)450℃,對(dui)油類溫(wen)度低(di)于(yu)(yu)350℃,壓力低(di)于(yu)(yu)5MPa的(de)(de)(de)場合,對(dui)于(yu)(yu)一般的(de)(de)(de)腐蝕性(xing)介質,最常用的(de)(de)(de)是耐酸石(shi)棉(mian)(mian)板(ban)(ban)(ban).在高壓設備及管道(dao)中,采用銅(tong),鋁,10號鋼,不(bu)銹鋼制成的(de)(de)(de)透鏡型或其他形狀的(de)(de)(de)金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)墊片(pian)。大多數墊片(pian)是從(cong)非金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)板(ban)(ban)(ban)裁下來的(de)(de)(de),或由專業工廠按規定尺寸(cun)制作,其材料(liao)為石(shi)棉(mian)(mian)橡(xiang)膠(jiao)板(ban)(ban)(ban),石(shi)棉(mian)(mian)板(ban)(ban)(ban),聚乙烯板(ban)(ban)(ban)等(deng);也有用薄金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)板(ban)(ban)(ban)(白鐵皮,不(bu)銹鋼)將石(shi)棉(mian)(mian)等(deng)非金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)材料(liao)包(bao)裹起(qi)來制成的(de)(de)(de)金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)包(bao)墊片(pian)。

異徑三(san)(san)通管(guan)件加工(gong)(gong)方法適應不(bu)同(tong)規格的管(guan)道(dao)上異徑三(san)(san)通管(guan)件加工(gong)(gong);其(qi)專(zhuan)用加工(gong)(gong)設備,結構簡單(dan),造價低(di)廉(lian),制造異徑三(san)(san)通管(guan)件不(bu)需要另(ling)外(wai)的注(zhu)(zhu)塑(su)機和的注(zhu)(zhu)塑(su)模具,可降低(di)此類管(guan)件的生(sheng)產(chan)成本,提高生(sheng)產(chan)效率.使(shi)管(guan)子(zi)與管(guan)子(zi)相互連接(jie)的零件,連接(jie)于(yu)管(guan)端。

還有(you)(you)一(yi)(yi)種(zhong)(zhong)用(yong)薄鋼(gang)帶與(yu)石(shi)棉帶一(yi)(yi)起(qi)繞(rao)(rao)制而成(cheng)的(de)纏繞(rao)(rao)式墊片(pian).高(gao)壓(ya)墊片(pian)與(yu)密封(feng)(feng)面的(de)接(jie)觸寬度非常窄(線接(jie)觸),密封(feng)(feng)面與(yu)墊片(pian)的(de)加工光(guang)潔度較高(gao).異徑法蘭密封(feng)(feng)面的(de)型式有(you)(you)三種(zhong)(zhong):平面型密封(feng)(feng)面,適(shi)(shi)(shi)用(yong)于(yu)壓(ya)力(li)(li)不高(gao),介(jie)質無毒的(de)場(chang)(chang)合;凹凸密封(feng)(feng)面,適(shi)(shi)(shi)用(yong)于(yu)壓(ya)力(li)(li)稍高(gao)的(de)場(chang)(chang)合;榫槽密封(feng)(feng)面,適(shi)(shi)(shi)用(yong)于(yu)易燃(ran),易爆(bao),有(you)(you)毒介(jie)質及壓(ya)力(li)(li)較高(gao)的(de)場(chang)(chang)合.墊片(pian)是一(yi)(yi)種(zhong)(zhong)能產生(sheng)塑性(xing)變形,并具有(you)(you)一(yi)(yi)定強度的(de)材料制成(cheng)的(de)圓環(huan)。
