金屬(shu)纏繞(rao)墊(dian)片(pian)是(shi)目前應用廣泛(fan)的(de)(de)(de)一種(zhong)密(mi)(mi)封(feng)(feng)墊(dian)片(pian),為半(ban)金屬(shu)密(mi)(mi)合(he)墊(dian)中回(hui)彈性的(de)(de)(de)墊(dian)片(pian),由V形或(huo)W形薄鋼帶與各種(zhong)填充料交替纏繞(rao)而成,能(neng)耐(nai)高溫、高壓和(he)適應超低溫或(huo)真空(kong)下的(de)(de)(de)條件使用,通(tong)過改(gai)變(bian)墊(dian)片(pian)的(de)(de)(de)材料組合(he),可解決(jue)各種(zhong)介(jie)質(zhi)對墊(dian)片(pian)的(de)(de)(de)化(hua)學腐蝕問題,其結構密(mi)(mi)度可依據不同的(de)(de)(de)鎖緊(jin)力要求來制作,為加強主(zhu)體和(he)準(zhun)確定位(wei),纏繞(rao)墊(dian)片(pian)設有(you)金屬(shu)內加強環和(he)外定位(wei)環,利用內外鋼環來控制其大壓緊(jin)度,對墊(dian)片(pian)接觸的(de)(de)(de)法(fa)蘭(lan)密(mi)(mi)封(feng)(feng)面(mian)(mian)的(de)(de)(de)表面(mian)(mian)精度要求不高。
回彈性優良的金屬纏(chan)繞墊片(pian)能夠對(dui)管道(dao)系統(tong)的壓力熱循環和(he)振動(dong)進行
自動調整,特別適用于負荷不均勻、接合(he)力(li)(li)易松弛,溫度與壓力(li)(li)周期性變化(hua)、有沖(chong)擊或震動的場合(he)。是閥門(men)、泵、換熱器、塔、人孔、手(shou)孔等法蘭連(lian)接處的靜密封原(yuan)件(jian),廣泛(fan)地用于石化(hua)、機械、電力(li)(li)、冶金、造船、醫藥、原(yuan)子能和宇航(hang)等部門(men)。
在(zai)法蘭(lan)墊外(wai)觀設(she)計上(shang)為了安(an)(an)裝(zhuang)方便,根據墊片口徑大小(xiao),在(zai)墊片外(wai)圍焊(han)上(shang)2~8個定位帶,讓定位帶扣在(zai)法蘭(lan)孔上(shang),以防(fang)安(an)(an)裝(zhuang)時墊片移位或(huo)脫(tuo)落,節約(yue)了輔(fu)助材料及工時.一(yi)般分為以下幾(ji)種類(lei)型:
